Really Rocket Science - Observation

Bella Lancio di Razzi

Mon, 27 Oct 2008 05:51:57 -0700

Yes, the Delta rocket is still working. This time for the Italian COSMO/SKYMED-3 and the United Launch Alliance:

A United Launch Alliance Delta II rocket, on behalf of Boeing Launch Services, successfully launched the third Italian-built Constellation of Small Satellites for Mediterranean Basin Observation or COSMO-SkyMed 3 satellite at 7:28 p.m., October 24. ULA successfully launched the first two Cosmo satellites on Delta II vehicles June 7, 2007 and Dec. 8, 2007.
"ULA is pleased to have successfully launched the third of four critical Earth observation systems in this series for Boeing and Thales Alenia Space," said Jim Sponnick, ULA vice president, Delta Product Line. "With this 43rd successful commercial launch, the Delta II system continues its record of mission success, which is unparalleled in the U.S. space industry. This achievement is due to the hard work of our professional engineers and technicians along with the tremendous support we receive from our government, industry, and supplier mission partners. We look forward to many more Delta II launches in the years ahead."
Blasting off from Space Launch Complex 2, it marked the fifth successful Delta II vehicle launch procured by The Boeing Company through its commercial launch business. The ULA Delta II 7420-10 configuration vehicle featured an ULA first stage booster powered by a Pratt & Whitney Rocketdyne RS-27A main engine and four Alliant Techsystems (ATK) strap-on solid rocket boosters. An Aerojet AJ10-118K engine powered the second stage. The payload was encased by a 10-foot-diameter composite payload fairing.
ULA began processing the Delta II launch vehicle in Decatur, Ala., nearly two years ago. In February, the 1st stage arrived from Decatur followed by the 2nd stage in August. The vehicle was erected on its stand at the pad Sept. 16, with solid rocket booster installation completed Sept. 19. Hundreds of ULA technicians, engineers, and management worked to prepare the vehicle for the COSMO-3 mission.
Developed by Thales Alenia Space, Italia for the Italian Space Agency and the Italian Ministry of Defense, COSMO-3 is the third of the four COSMO-SkyMed satellites. Each satellite is equipped with a high-resolution Synthetic Aperture Radar operating in X-band and is one of a constellation of four radar satellites. The overall objective of the program is global Earth observation and relevant data responding to the needs of the military and scientific community, as well as to the public demand for environmental control.

Bread & Satellites

Wed, 15 Oct 2008 06:25:50 -0700

If you've spent some time in Ann Arbor, Michigan, you may have come across a Zingerman's -- a host of specialty foods delis, restaurants and related businesses. They're known for having one of the best mail-order breads in the U.S.

The University of Michigan's Student Space Systems Fabrication Laboratory is working on a micro-satellite about the size of a loaf of bread. The story, via Space Daily, gives us more:

U.S. scientists say they are developing a satellite about the size of a loaf of bread that will be deployed to study space weather.
The National Science Foundation-funded project called Radio Explorer, or RAX, is being led by the University of Michigan and the SRI International Corp., a California independent research and technology development organization.
The satellite, called CubeSat, is to be the first free-flying spacecraft, and will be built, in part, by members of the university's Student Space Systems Fabrication Laboratory.
CubeSats are approximately 4-inch cube-shaped devices that launch from inside a P-Pod -- a special rocket attachment developed by California Polytechnic State University and Stanford University.
The RAX satellite will essentially be made of three CubeSats and will measure the energy flow in the Earth's ionosphere, where solar radiation turns regular atoms into charged particles.
"This project will help us better understand space weather processes, how the Earth and sun interact and how this weather produces noise in space communication signals -- noise that translates to lower quality telecommunications capabilities and error in GPS signals," said Assistant Professor James Cutler, a co-principal investigator with physicist Hasan Bahcivan of SRI.

The grants from the National Science Foundation, who use a less-imaginative "half gallon carton of milk" metaphor, hopes to develop more student interest in space, too:

The National Science Foundation (NSF) has awarded a grant to SRI International, an independent non-profit research and development organization based in Menlo Park, Calif., to carry out the first space weather CubeSat mission.
CubeSats are tiny satellites with dimensions of 10��10��10 centimeters, weighing about 1 kilogram, and typically using commercial off-the-shelf electronics components.
Developed through joint efforts, California Polytechnic State University and Stanford University introduced CubeSats to academia as a way for universities throughout the world to enter the realm of space science and exploration.
According to atmospheric scientists, CubeSats have the potential to be excellent platforms for technology development and small science missions, and promote student involvement in design, fabrication and flight missions.
"One of the goals is to help train future space scientists and aerospace engineers," said Therese Moretto Jorgensen, program director in NSF's Division of Atmospheric Sciences. "CubeSats will also help answer questions in space weather such as the cause of disturbances in the ionosphere, and the rise and decay of the Earth's radiation belts during geomagnetic storms."

SRI International's team will include many, including support from NASA:

“SRI is excited about the NSF contract, and working in collaboration with the University of Michigan,” said Hasan Bahcivan, research physicist at SRI International. “This program provides a cost effective way to support space weather and atmospheric research. It is also well positioned to provide excellent training opportunities for students that hope to become engineers or scientists. We expect 20 to 30 students to take significant roles in the design, development, and science operations of the satellite.”
The project’s mission is designed to remotely explore small-scale ionization structures in the form of plasma turbulence that occurs in response to intense electrical currents in the space environment. The structures can adversely impact communication and navigation signals by perturbing the refractive index along the signal propagation paths. By utilizing signals from powerful transmitters on the ground and receiving the scattered signals in space, researchers are achieving effective and powerful space-based radar to probe these structures, which would be expensive to accomplish via a stand-alone satellite radar.
"We have a multidisciplinary, cross-departmental team working on the project, that includes several engineers and faculty, and a large number of undergraduate and graduate students," said James Cutler, an assistant professor in the Aerospace Engineering Department at the University of Michigan. "My research laboratory will be partnering with several space-related classes and the Student Space Systems Fabrication Laboratory (S3FL) to build and fly RAX."
The first launch opportunity for the NSF satellite program will be with the Department of Defense Space Test Program, and is scheduled for December 2009 aboard a Minotaur-4 launch vehicle out of Kodiak, Alaska. Commissioning and launch support for the mission will be provided by NASA Goddard Space Flight Center Wallops Flight Facility.

This is the kind of government support we need to develop the future of rocket science.

Looks Like Kutztown

Fri, 10 Oct 2008 12:30:48 -0700

GeoEye-1's first image released of Kutztown University in Pennsylvania:

GeoEye, Inc. (NASDAQ: GEOY), a premier provider of satellite, aerial and geospatial information, released today the first, color half-meter ground resolution image taken from its GeoEye-1 satellite. The satellite has been undergoing calibration and check-out since it was launched on Sept. 6 from Vandenberg Air Force Base in Calif. The Company will begin selling GeoEye-1 imagery products later this fall.
The Kutztown University image shows the campus, which includes academic buildings, parking lots, roads, athletic fields and the track-and-field facility. The image was collected at 12:00 p.m. EDT on Oct. 7, 2008 while GeoEye-1 was moving north to south in a 423-mile-high (681 km) orbit over the eastern seaboard of the U.S. at a speed of four-and-one-half miles per second. GeoEye-1 was built by General Dynamics Advanced Information Systems in Gilbert, Ariz. The imaging system was built by ITT in Rochester, NY.

Smile For The Satellite

Thu, 02 Oct 2008 13:30:58 -0700

Chelyabinsk is one happy town. They've come a long way from being "the most contaminated spot on the planet."

Here's an interesting story from Slashdot:

Citizens of the Russian town Chelyabinsk calculated when the satellite, QuickBird, which takes images for Google Earth and Google Maps, would cross above their city and used people to make a giant smiley face. A rock concert on the main square attracted many people and everyone got a yellow cape. It looks like someone at Google was quicker than usual to put up the new data. Maybe Google likes the idea of an entire town working hard to get its 15 minutes of fame. The article has a screenshot of Google Maps and images taken directly at the event."

They did pretty good:

This isn't the first time that Google Earth or Google Maps has captured something interesting from space. Longtime readers of Really Rocket Science will recall the Ipod that fell to Earth, which we wrote about way back in March of 2006:

But there's more to be seen than "Ipods" and smiley faces in the world of Google Earth. GoogleSightSeeing.com -- whose tag line is "Why Bother Seeing the World for Real?" has a great series of blog posts on cool sights that you can see right from your computer desk. Be sure to check out this map of global points of interest.

Pentagon's BASIC Approved

Wed, 17 Sep 2008 20:05:45 -0700

Via the AP:

The Pentagon has approved plans to buy and launch two commercial-class imagery satellites to complement its classified constellation of spy satellites.

The Pentagon will also increase the amount of imagery purchased from private companies operating similar satellites already in the sky.

The decision last week caps months of wrangling between the Air Force, the National Reconnaissance Office, and the National Intelligence Directors Office and the Office of the Secretary of Defense over which agency would buy the satellites for about $1.7 billion. The satellites are to be launched around 2012. The NRO will head satellite acquisition, according to Pentagon documents obtained by The Associated Press.

But critics of the program say the Pentagon is spending billions to recreate and compete with private companies like GeoEye of Dulles, Va., and DigitalGlobe of Longmont, Colo., which are expected to put four new satellites into orbit by 2013. On its face the decision conflicts with the president's national security space policy, which directs the government to buy as much commercial imagery as possible to help the companies withstand competition from subsidized foreign satellite companies.

Purchasing the imagery from the companies may also be less expensive. The GeoEye 1 satellite was launched on Sept. 6 for $502 million, including the satellite, launch, insurance and four ground stations, according to company spokesman Mark Brender. It is expected to begin taking 16-inch resolution imagery this weekend.

The Pentagon may decide to turn over operation of the new satellites to the private companies, the internal document notes.

The new satellites will comprise the Broad Area Space-Based Imagery Collection satellite system, or BASIC. They will also have 16-inch resolution. They could be used to spy on enemy troop movements, spot construction at suspected nuclear sites or alert commanders to militant training camps. Their still images would be pieced together with higher resolution secret satellites into one large mosaic.

The new satellite system is meant to bridge what intelligence agencies fear will become a gap caused by the cancellation in September 2005 of a major component of the Future Imagery Architecture system overseen by the National Reconnaissance Office. The primary contractor, The Boeing Co., headquartered in Chicago, ran into technical problems developing the satellite and spent nearly $10 billion, blowing its budget by $3 billion to $5 billion before the Pentagon pulled the plug, according to industry experts and government reports.

A single satellite can visit one spot on Earth once or twice every day. BASIC's additional satellites will allow multiple passes over the same sites, alerting U.S. government users to potential trouble, humanitarian crises or natural disasters such as floods.

Maybe now we'll be able to see license plates from space.

Google Maps is about to get even better

Tue, 09 Sep 2008 05:36:47 -0700

The GeoEye-1 satellite – the world's highest resolution, commercial Earth-imaging satellite - was launched on Saturday.

You’ll soon be able to check out the satellite’s images for yourself:

ars technica In return for undisclosed terms, Google got two considerations: its logo on the side of the launch vehicle, and exclusive use of the mapping images that the satellite produces.

The satellite maker, General Dynamics Advanced Information Systems, says the GeoEye-1 cost $500 Million to build and launch and its imaging services could be sold for anything from environmental mapping to agriculture and defense. Funding for the project came from commercial satellite company GeoEye and the Defense Department’s National Geospacial-Intelligence Agency

Predicting Space Weather

Mon, 21 Jul 2008 09:59:27 -0700

On reading that title, you might be asking yourself “why in the world would I need to predict space weather?” Well, I’ll tell you. Space weather – the range of high-energy radiation, such as X-rays and gamma rays, that constantly bombard the Earth's atmosphere – affects the performance of some of your favorite gadgets, like GPS and satellite TV.

With this camera, scientists can predict changes is space weather, allowing for communications companies to compensate for electromagnetic interruptions to their signals. Never again will your Planet of the Apes marathon be spoiled by a bad signal. Oh, and it’ll help the military predict and plan for interruptions in their communications too.

The project – the Global-Scale Observations of the Limb and Disk – is known by a catchy acronym: GOLD.

The GOLD Camera will fly on an SES AMERICOM satellite. Physicist Richard Eastes, who leads the GOLD project, says this is the first time that a NASA instrument has flown on a commercial communications satellite.

This is the second “hosted” payload for an AMERICOM spacecraft just this month. The other was for the Air Force’s CHIRP (Commercially Hosted Infrared Payload).

Russian Hide-N-Seek

Wed, 16 Jul 2008 13:31:03 -0700

As Mark Twain said, "Always tell the truth. That way, you don't have to remember what you said." The Russian Defence Ministry's Information and Public Relations Directorate ought to make a note of it.

Back in April, Red Orbit reported they denied a major satellite malfunction:

"In connection with reports published in some mass media alleging that the Kosmos-2421 satellite has disintegrated, we would like to report that its planned flight programme has been fulfilled. After switching off its on-board equipment, the satellite was taken out of service in accordance with the established procedure", reads the directorate's report received by Interfax-AVN today.
According to the Defence Ministry, "the Kosmos-2421 satellite remains in its orbit, the parameters of which correspond to the predicted ones, and is under steady observation by means of the national system of space control".
The ministry added that there are three more space objects in orbits close to Kosmos-2421. "One of them is a stage vehicle of a carrier rocket, and the other two - fragments of a launch [vehicle]", the report says. [Passage omitted on "a NASA website" report on the alleged disintegration of the satellite; background]
Originally published by Interfax-AVN military news agency website, Moscow, in Russian 1431 15 Apr 08.

Well, according to NASA's Orbital Debris Quarterly News, that's not entirely true:

Late in the first quarter of 2008, the U.S. Space Surveillance Network (SSN) detected a significant fragmentation of Cosmos 2421 (International Designator 2006-026A, U.S. Satellite Number 29247), which produced approximately 300 detectable debris (see ODQN, Vol. 12, Issue 2). Two more fragmentation events of the same spacecraft during April-June added another 200 or more large debris (greater than 5 cm) to the near-Earth space environment, once again raising questions about the peculiar nature of this satellite class.

You can count on our friends at U.S. Strategic Command's Space Surveillance Network to keep an eye on them.

First Storm of the Season

Mon, 07 Jul 2008 11:53:09 -0700

It's officially hurricane season and Bertha is gearing up to be the year's first storm.

Whether you might find yourself in the eye of the storm or you're just intrigued by extreme weather, you're sure to appreciate the fun tools that the National Weather Service puts out for the public. This one lets you track the storm's movements. And this one shows wind speeds.

How do they get all the data for these cool images? Why satellites, of course. And the NOAA has a full arsenal. But how does all the information coming from those satellites turn into something we can understand, like this animation of the season's first hurricane?

With Giovanni it's simple. And no, that isn't the name of an Italian tropical storm guru...

Giovanni is actually an acronym for the GES-DISC (Goddard Earth Sciences Data and Information Services Center) Interactive Online Visualization ANd aNalysis Infrastructure.

In other words, it's a web-based application developed by NASA that is available to anyone with a computer and a bit of spare time. But beware, for those of us who've lost hours tooling around on Google Earth, this can become a bit addictive...

Shake, Shake, Shake

Wed, 11 Jun 2008 08:54:32 -0700

Mobile Satellite Ventures is proposing a system to help predict earthquakes in the U.S. Naturally, it's a satellite-based system:

Mobile Satellite Ventures (MSV) today announced that it has joined with the Central United States Earthquake Consortium (CUSEC) to form a new satellite mutual aid radio talkgroup (SMART) dedicated to the preparation for and response to earthquakes throughout the central United States.
CUSEC is a partnership of the federal government and eight states most affected by earthquakes in the central U.S. including Alabama, Arkansas, Illinois, Indiana, Kentucky, Mississippi, Missouri and Tennessee. The organization serves as the coordinating hub for the multi-state region and as a partnership of organizations to mediate disasters and save lives caused by earthquakes in the central U.S.

MSV is expected to shake things up with their new satellite, MSV-1, expected to launch in 2009 and based on Boeing's GeoMobile platform (like Thuraya, but bigger). Wait a minute: where's California? They have their own earthquake people. But central U.S.? There was an earthquake measuring 5.2 on the Richter Scale in the Wabash Valley on 18 April 2008, via The Southern Illinoisan:

An earthquake centered in southern Illinois rocked people awake across the Midwest early Friday, surprising residents unaccustomed to such seismic activity.
The quake just before 4:37 a.m. was centered 6 miles from West Salem, Ill., and 66 miles west of Evansville, Ind.
Initially pegged as a 5.4 earthquake, the U.S. Geological Survey revised its estimate to give it a value of 5.2.
West Salem is in Edwards County, and dispatcher Lucas Griswold says the sheriff's department received several calls about the earthquake but only reports of minor damage and no injuries.
``Oh, yeah, I felt it. It was interesting,'' Griswold said. ``A lot of shaking.''

Meanwhile, on the other side of the world, Australian Broadcasting is reporting a new satellite system for predicting earthquakes using ionospheric dimpling:

The theory suggests that much of earth's rock has soaked up water, which has later been exposed to extreme heat and pressure inside the earth. Those conditions break apart the water and create the electrically conductive crystals that exist inside most rocks, as well as byproducts such as oxygen.
As pressure builds before an earthquake, the oxygen molecules inside the rocks undergo chemical reactions, creating a positive electrical charge that radiates out toward the earth's surface.
"It's similar to how an electrical charge radiates through a battery," says Freund.
The charge creates a subtle fluorescent, infrared glow and a magnetic field one to two weeks before a major earthquake.
That light shines into space, the theory goes, where satellites can register the change.
Low-resolution thermal cameras aboard the proposed satellites would scan the earth to detect earthquake precursors, says Eves.
The positively charged magnet creates a dimple, up to 20 kilometres deep, in the earth's atmosphere by attracting negatively charged ions from as far away as 600 kilometres above the surface of the Earth.
To detect this ionospheric dimpling, the satellites would monitor the existing Global Positioning Satellite System with three small GPS antennas on its side. As each GPS satellite comes up over the horizon, its signal would pass through the ionosphere. Any dimpling would change that signal.
The theory is not without skeptics.
"As far as I know, there is no published research to suggest that this will work," says Dr Mike Blanpied, who is with the United States Geologic Survey's Earthquake Hazards Program.

This early-warning system was reported by the Wall Street Journal last month:

Early in May, NASA earth scientists monitoring infrared images of the earth noticed unusual patterns in southwestern China. One sent an email to colleagues, noting: Something is happening in Sichuan province.
For Friedemann Freund, a chemist-turned-NASA geophysics researcher, it was more support for his simple, though hotly contested theory: Earthquakes are the culmination of drawn-out physical processes that can be tracked sometimes more than a week ahead of the main event.

The main idea: Rocks put under enough pressure -- for example, when tectonic plates shift -- turn into batteries. The resulting electrical currents can travel miles into the earth, Dr. Freund says. The infrared images observed by NASA, for example, were concentrated several hundred miles from the epicenter of the roughly 8.0 magnitude earthquake that struck on May 12, killing at least 34,000 people.
Dr. Freund describes his discovery as simple, made at 2 p.m. on a Friday afternoon in early 2005 just before he and his graduate students finished packing up a temporary laboratory they had been using. For experiment No. 167, one for the road, they decided to use a copper contact to test whether a squeezed rock emitted a current. It did.
"This is something that should have been discovered 50 years ago," he said.
Certainly, people have tried. For more than a century, researchers have debated the pursuit of the "holy grail" of earthquake prediction. There is still no widespread support for linking electromagnetic signals, infrared emissions or atmospheric changes to an approaching quake.

Satellites are used to communicate seismic data, and transmitting videos, of course. The prospect of being able to predict such events many days in advance seems like a real possibility. Count on the Smithsonian to present it, probably based on a published piece by Dr. Ouzounov of George Mason University.

Volcanoes

Tue, 20 May 2008 10:37:34 -0700

Earlier this month a volcanic eruption in Chile wowed the world, and produced one of the most magnificent natural images ever.

The eruption actually came from a volcanic caldera, Chaitén. The eruption forced the evacuation of nearby towns, merged two massive craters, and increased the possibility of even more activity. You can watch video (in Spanish) of the disaster here.

But beyond YouTube recaps of eruptions, you can discover images of the volcanoes, active and dormant, around the world. The Italian Government has publicly accessible webcams of volcanoes. And this site has mapped, photographed, and documented every volcano in the world (including Chaitén). Pretty amazing.

Satellites are keeping tabs too. This site has satellite images of some of the world's largest volcanoes, including some very close to home.

But, of course, Volcanoes are not limited to Earth. Jupiter has some of the our galaxy's more active volcanic activity:

Before the Voyager probes visited Jupiter, if you had described Io to a literary critic it would have been declared overwrought science fiction. Jupiter's strange moon is literally bursting with volcanoes. Dozens of active vents pepper the landscape with volcanic rings the size of California. The volcanoes themselves are the hottest spots in the solar system with temperatures exceeding 1800 K (1527 C) about 1/3 the temperature of the surface of the Sun. The plumes which rise as much as 500 kilometers into space are so large they can be seen from Earth by the Hubble Space Telescope. Confounding common sense, these high-rising ejecta seem to be made up of, not blisteringly hot lava, but frozen sulfur dioxide. For a world dominated by fiery volcanoes, it's curious that Io is also very, very cold. The ground just around the volcanic vents is literally sizzling, but most of Io's surface is 150 degrees or more below 0 C.

What powers the tremendous volcanic activity? Tides! But the tides on Io are not like ocean tides we're familiar with on Earth. The gravitational fields of Jupiter and its large moons Europa and Ganymede cause tidal bulges in the solid crust of Io that are as high as 100 meters (330 feet). As Io orbits the giant planet, the bulge moves, flexes the crust, and heats Io's interior like a paper clip bent rapidly back and forth. Infrared observations have shown that the thermal energy released by Io's hot spots is on the order of 125 trillion watts which is about 2.5 W/m2. By contrast the moon's outward heat flow is 0.02 W/m2 and the Earth's average heat flow is 0.06 W/m2.

A year ago, NASA's New Horizons probe captured a number of amazing images, showing massive plumes of ash, believed to be a result of Volcanic activity.

Britain - a space power?

Mon, 03 Mar 2008 13:58:52 -0800

Well, sort of. With a little investment, the Brits could be an important player in space exploration and business:

Britain can play an important role in space exploration by exploiting its skills in the satellite sector rather than joining the competition in manned space flights, according to David Williams, head of Avanti, a satellite communications company. "There aren't unlimited resources - we have to prioritise in areas where we have an economic advantage," he said.

Britain should be creating the communications infrastructure that will be needed as exploration expands deeper into space, he said. Countries such as the US, China, India and Russia, as well as the European Space Agency, are working on deep-space exploration. "If mankind is going to exploit the resources of the solar system, you are going to have to travel over very long distances and you are going to have to communicate over very long distances and you will need a network of data-relay satellites. The UK has a big advantage. We have the opportunity to control the space internet, which is going to be this network of data-relay satellites."

As The Guardian explains, these hopes are part of the government's space strategy, drawn up by the British National Space Centre, which aims to double the number of British companies involved in the space business by 2012. Unfortunately, a trip to the moon is NOT part of the plan:

However, many space enthusiasts will be disappointed to learn that the plan has little to say about long-held aspirations for a British astronaut, though officials are to launch a review of the costs and possible benefits of human spaceflight.

In the 1960s ministers opted out of all crewed space missions, a stance governments have maintained since, but last year several key groups of experts, including the Commons science committee and a panel commissioned by the BNSC, warned that Britain risked being left behind if it did not end its long-standing opposition.

The failure to back a British astronaut dismayed some experts who believe Britain has missed any chance of being involved in European and Nasa plans to send humans back to the moon.

"There's no commitment at all from this strategy. We're the only developed nation that doesn't have an astronaut, despite the fact that we're the fifth largest economy," said Nick Spall of the British Interplanetary Society, who has been leading a campaign for a British astronaut.

"The government has missed a huge trick in terms of being able to offer inspiration to young people. In particular the chances of the UK contributing to a return to the moon, from a human spaceflight point of view, are very limited now. If we don't have an astronaut with spaceflight experience we won't get a look in on either of those missions."

Instead of "catching up" with other national manned space programs, Britain is going to try to conquer what it beleives to be an emerging focus of space research – climate change and disaster warning/relief:

The threat of climate change to planet Earth is to become the cornerstone of Britain's role in the heavens, following an extensive review of space policy. British experts will develop satellites and other sophisticated technology capable of gazing back at Earth and taking the pulse of the planet from orbit, by monitoring melting ice sheets, dying rainforests and violent storms, under plans to be published by the government today.

The satellites will help create an early warning system for natural disasters, including hurricanes and tsunamis, and help to police international carbon-cutting agreements, such as pledges to avoid deforestation in some of the world's environmental hotspots.

The move is at the heart of the government's space strategy, drawn up by the British National Space Centre, which aims to double the number of British companies involved in the space business by 2012.

Under the plans Britain will become home to a major new European Space Agency facility based at Harwell in Oxfordshire. It will be dedicated to understanding climate change from space and developing robotics for space exploration. Britain is the only major contributor to the ESA that does not yet have its own facility.

According to BNSC officials, Earth observation from space is prioritised to help Britain become a hub for expertise in environmental science and disaster relief. During the 1990s natural disasters killed half a million people and caused £380bn of damage. Some 80% of those disasters were weather related, the report states.

It says: "Global satellite-based monitoring systems underpin our understanding of the health of the planet, alert us to dangers and speed up our responses. Satellites have a significant role in accurately assessing changes in sea [level] and temperature, the melting ice caps, and the effects of solar activity on the Earth and its environment."

Host My Payload

Wed, 27 Feb 2008 09:24:05 -0800

Very interesting news from California this morning about Space Systems/Loral and Northrop Grumman's Space Technology division getting together to go after U.S. government business. Building spacecraft for fully-funded government projects can be more profitable than going after commercial projects. Sounds like a simple agreement:

"The agreement with Northrop Grumman will allow SS/L to cost-effectively add capacity to address increased near-term commercial satellite opportunities," said Pat DeWitt, chief executive officer, Space Systems/Loral. "The agreement will also streamline the process for our companies to collaborate on providing the world's best satellites for both civil and defense applications."
"The resulting strategic agreement will be important to increasing our competitiveness. These initiatives will present win-win opportunities for both companies and our U.S. government customers," said Alexis Livanos, corporate vice president and president of the company's Space Technology sector. "For some of our mission areas, we believe that assured access to SS/L's 1300 bus and bus subsystems would improve our cost and delivery schedule competitiveness. In addition, hosted payloads hold the promise of providing us greater ability and flexibility to rapidly respond to our government customers' evolving needs."

Some of these new opportunities included "hosted payloads" where specialized instruments or entire subsystems can be added on to a satellite bus whose primary mission is paying most of the build cost. Given the importance of the role space plays in today's C4ISR systems (Command, Control, Communications, Computers, Intelligence, Surveillance and Reconnaissance), and the expected ends-of-life of the spacecraft currently in orbit, we'll need a bunch of new launches in the short term. Factor in programs being behind schedule -- with some going way over budget -- and you might conclude we have a problem, Houston. Intelsat General is going after this market, too.

Northrop Grumman is involved in a new moon mission for NASA, the LCROSS (Lunar CRater Observation and Sensing Satellite):

Ready, Aim

Tue, 19 Feb 2008 19:30:58 -0800

We've been following this story for a few weeks now, and it is astounding how much attention has been paid to it. A top-secret U.S. observation satellite that's out of control is set to be shot out of the sky precisely so it brings no harm to the public. Over the Pacific Ocean, for example, would be a good location. Now the U.S. Navy has issued a "notice to airmen," signaling just that:

02/062 (A0038/08) - AIRSPACE CARF NR. 90 ON EVELYN STATIONARY RESERVATION WITHIN AN AREA BNDD BY 3145N 17012W 2824N 16642W 2352N 16317W 1909N 16129W 1241N 16129W 1239N 16532W 1842N 17057W 2031N 17230W 2703N 17206W SFC-UNL. 21 FEB 02:30 2008 UNTIL 21 FEB 05:00 2008. CREATED: 18 FEB 12:51 2008

The Register explains what this means:

A "CARF" (Central Altitude Reservation Function) designation indicates a NOTAM intended to keep commercial and private flights clear of military operations, and SFC-UNL means the height band of this warning zone reaches from the surface to "unlimited" altitude - in other words all the way into space. The UTC time referred to is the same as UK time, so the zone exists from 0230 to 0500 on Thursday morning for British readers.
As will be evident, the barred area is a cool 1,400 miles long and nearly 700 miles wide at the surface, giving the US Navy plenty of elbow room to fire their interceptor missiles up into the descending spacecraft's path.
Reports have it that three US Aegis air-defence warships, the cruiser Lake Erie and the destroyers Decatur and Russell, will be waiting for the satellite west of Hawaii. Each ship carries a specially modified Standard SM-3 interceptor, originally intended for defence against lower-flying ballistic missile warheads. The three interceptors are on separate ships in case of a technical issue with the Aegis radar and fire-control system.
As it passes over the firing area, the satellite will be approximately 3,000 miles and ten minutes out from the western coast of Canada, the next land it will pass over. The satellite has much more mass than the soaring "exo-atmospheric kill vehicle" it will smack into, so this gives some idea of the onward track the wreckage might follow in the event of a hit.

Google Earth kmz file by Alan Clegg is worth a look.

What can we expect on Thursday? Take a look at this Japanese test from last December:

Uncontrolled Re-entry by Spy Satellite

Wed, 30 Apr 2008 20:01:50 -0700

Apparently, a spy satellite is no longer in control and could crash to earth very soon. Today's New York Times has some detail:

Specialists who follow spy satellite operations suspect it is an experimental imagery satellite built by Lockheed Martin and launched from Vandenberg Air Force Base in California in December 2006 aboard a Delta II rocket. Shortly after the satellite reached orbit, ground controllers lost the ability to control it and were never able to regain communication.

Of course, somebody has to think of the worst. This report from Canadian TV picks up on the hydrazine threat:

Gordon Johndroe, a spokesman for the U.S. National Security Council, said appropriate government agencies are monitoring the situation.
"Numerous satellites over the years have come out of orbit and fallen harmlessly," he said. "We are looking at potential options to mitigate any possible damage this satellite may cause."
It's unknown whether the U.S. may attempt to destroy the spy satellite before it re-enters the atmosphere.
"It's not all that easy," said Atwood. "You're not going to shoot it down, you're just going to explode it into a million pieces that are ultimately going to fall on the Earth."
An anonymous government source told AP that the satellite contains a rocket fuel called hydrazine, which is a toxic chemical and can be harmful to anyone exposed to it.

One of the news "sources" cited a launch out of Vandenburgh AFB on a Delta II rocket. Probably the NROL-21, a classified NRO spacecraft. Judging from its orbit (353 km x 380 km, 58.5°), it's probably an experimental radar, according to Gunther:

NROL 21 is the cover-name for one-off classified satellite. Although nothing is known about the mission, the orbit hints for an experimental radar reconnaisance satellite.
A few weeks after launch reports emerged, that grond stations were unable to communicate with an expensive experimental U.S. spy satellite launched last year by the U.S. National Reconnaissance Office (NRO). Efforts were said to be continuing to reestablish communication with the classified satellite, which cost hundreds of millions of dollars, but "the prognosis is not great at this point," said the defense official, who asked not to be identified.The official said the problems were substantial and involved multiple systems, adding that U.S. officials were working to reestablish contact with the satellite because of the importance of the new technology it was meant to test and demonstrate. An other source said the satellite had been described to him as "a comprehensive failure."
In August 2007 the satellite has been declared a complete loss and will be allowed to decay from orbit.

I doubt the re-entry will be as pretty as the launch was...

It certainly will not have an on-board camera like the launch did (fast forward to 2:35 -- that's when the action begins):
