Really Rocket Science

You've seen Back to the Future and the De Lorean time machine, but what is a flux capacitor?

It's the Y-shaped flashing light device (powered by 1.21 jigowatts) that turns a sports car into a time machine. How does/did it work? "Doc" couldn't even explain it:

It is not described in the films exactly how the flux capacitor worked beyond that of a typical plot device or a typical deus ex machina device, though Doc mentioned at one point that the stainless steel body of the DeLorean has a direct and influential effect on the "flux dispersal", though he was interrupted before he could finish the explanation. The flux capacitor required 1.21 gigawatts of electricity to operate.

You can make your very own Flux Capacitor (but, PLEASE, do not toss it in your car, cross your fingers, and go 88 mph in a parking lot). Instructables has the instructions. Not a lot of electronics experience is needed, and most of the equipment is available at your local hardware store and Radio Shack. The Flux is housed in an ordinary fuse box.

Too complicated? You can buy one here for $250. A small price to pay for time travel capabilities. And this (more-expensive) dealer will even provide a time-travel, money back guarantee (read closely):

This item may be expensive, but can you place a price on time travel? NOTE: Special return policy: If you are not 100% satisfied, you may return this product for a full refund, in no LESS than 30 days before you purchase it!

Once you have have your Flux, get started on the rest of the De Lorean time machine:

Earlier this year, the USS Erie successfully shot down an errant satellite in a real-world mission.

And, later today, the ship and its sea-based missle defense system will get a chance to prove itself again:

The test, off Kauai, is the latest test of the military's sea-based missile defenses, called the Aegis ballistic missile defense program.

The military will fire a Scud-like missile, which has a range of a few hundred miles, from a decommissioned amphibious assault ship, the USS Tripoli.

USS Lake Erie, a Pearl Harbor-based Navy cruiser, will fire two interceptor missiles at the target with the intention of shooting it down in its final seconds of flight.

If all goes well, the intercept should occur within the Earth's atmosphere, or within 100 miles of the Earth's surface.

The Aegis system accomplished a similar task once before: two years ago, the Lake Erie shot down a missile fired from the Pacific Missile Range Facility on Kauai in its final stage of flight.

In February, the ship successfully shot down a U.S. spy satellite in the Aegis' system's first real-world mission.

The satellite had lost power and become uncontrollable, creating worries it would break up and spread debris over several hundred miles if it fell to earth.

The Hawaii-based, Star Bulletin has more details.

The Navy said yesterday that on Tuesday the mission, named Stellar Scorpion, was blessed at the Barking Sands missile facility by "Uncle Tom" Takahashi, who named the Lake Erie's two interceptor missiles "the crashing sound of the ocean" and "the ear of the earth," respectively.

Being a decommissioned helicopter-carrier, the USS Tripoli (photo above) seems like a pretty odd choice to be involved in this exercise. The "Semper Princeps" (Always First), as they call it, has been around since 1964, and decommissioned (but strangely still very active) since 1995:

She was decommissioned in 1995 and as of 2004, she was on loan to the Army, but remained laid up at Mare Island Naval Shipyard. In December 2006, the ship was towed to Pearl Harbor, Hawaii, where it now has a high-tech role as a launch platform with the nation's developing ballistic missile defense program. Three times the ship was towed some 100 miles off shore and used to launch small ballistic missiles, which are then intercepted by Terminal High Altitude Area Defense Missiles, test-fired from the Pacific Missile Range Facility. The last test in the series was performed October 26, when the ship fired a "scud-like" missile, which was successfully intercepted. The ship will be towed back to the San Francisco Bay Area for the winter. Kaua'i lacks a suitable land-based launch site, and the costs of building one would far exceed the approximately $600,000 per year it costs to use the old warship, so the vessel will return to Pearl Harbor for a second series of tests in late spring 2008.

Out in the bush, you need an airplane to get around effectively. You can get by with a snowmoble in the winter, but how much can you cover in a day? Alaska is a big state, spanning 663,267 square miles (that's 367 million acres, cowboy). Since the early 1970s, Alaska's telephone system has been using satellite, primary using AT&T Alascom's Aurora satellites (currently Aurora III; co-named AMC-8). Pretty extensive network, highlighted by the Alyeska Pipeline:

When Galaxy 18 launched in May, we didn't think they'd be cutting over some of the services from the Galaxy 10R spacecraft so quickly.  End-of-life for G10R was originally projected to be 2015, but after a XIPS problem, it was cut short. One of the big customers on that bird, GCI, moved nine transponders of traffic yesterday:

GCI announced today that it successfully transitioned all of its rural telecommunication services last night to the Galaxy 18 satellite. This satellite will provide long-distance, Internet, distance education and telehealth services throughout rural Alaska for the next 14 years.

“The success of last night means rural Alaskans will stay connected to the most advanced network in Alaska,” said Ron Duncan, GCI president and CEO. “It also provides major businesses in Alaska and carriers in the lower 48 states the ability to directly touch customers virtually anywhere in Alaska.”

GCI owns nine transponders on Galaxy 18 and will take possession of a tenth transponder in approximately two weeks. GCI will lease the transponder capacity from Intelsat. However, GCI will be required to account for this arrangement as a capital lease. This will result in a capital lease obligation, and corresponding long-term asset, in the approximate amount of $98 million.

Hmm. At that price, it seems to work out to approximately $58,000 per month per transponder, and that ain't a bad price. I suppose if the oil keeps pumping, there will always be money to pay for satcom services. Keep us rocket scientists busy for years.

Here's where the oil ends up, in Valdez:

Longtime readers here at Really Rocket Science know that we're always impressed with next generation technology.

Today, this press release from AFS Trinity Power Corporation caught our eye: 

 Two XH-150 prototypes are returning this week to the Seattle area after being unveiled at the North American International Auto Show in Detroit and then traveling to cities across the U.S. to demonstrate the car to carmakers, government officials and the driving public, including a ride-and-drive demonstration on Earth Day for members of Congress in the Nation's Capital.

Road tests of the XH-150 at Michelin's Laurens Proving Grounds in South Carolina prior to the Detroit unveiling demonstrated extreme fuel economy without sacrificing performance. Test reports indicated the XH-150 traveled 41.9 miles without burning an once of fuel in a mixed urban/highway driving cycle, achieved all-electric highway speed of 87 MPH, accelerated faster to 60 MPH than comparable gasoline-only models (11.6 seconds) and, in full hybrid mode, delivered zero to 60 in just 6.9 seconds.  Along with dramatically reducing vehicle emissions, the XH-150 is expected to significantly reduce the cost of operating a car. It uses only one dollar of off-peak electricity to provide enough power for the average driver's 40 miles of daily driving and can achieve 150 miles per gallon during a typical 340 mile week. No other hybrid or plug-in hybrid of which AFS Trinity is aware has demonstrated the ability to achieve such fuel economy, range,  highway speed and acceleration.

The Governor of Washington, along with local and state officials, will be tooling near South Lake Union in Seattle today to celebrate the homecoming of the incredible vehicle.

So what's it like? Check out these videos and these images for more on just how normal the future actually looks.

With the launch of STS-124, a great site for kids from NASA, featuring Buzz Lightyear, is up. And Buzz Lightyear's in space, too:

Seven astronauts who will fly into orbit aboard space shuttle Discovery will have comfortable seats for the climb into space. An eighth space ranger won't have a seat at all. In fact, he will be packed tight inside a box and won't even get to enjoy the ride up.

But it's nothing veteran spaceman Buzz Lightyear can't overcome.

The good news is that he'll have some sports shows to listen to, along with a host of jerseys that have been to the Champs Elysees in Paris for the Tour de France and to the Super Bowl.

More accustomed to soaring among the galaxies on fold-out wings and a backpack rocket, Lightyear will take to space on Discovery’s STS-124 mission stowed inside a locker in Discovery's crew compartment. The 12-inch-tall action figure is flying as part of a partnership between NASA and Disney Parks to encourage students to pursue studies in science, technology and mathematics, one of NASA’s main educational goals.

Disney’s Youth Educational Series and NASA have developed an online program known as the Space Ranger Education Series. It includes fun educational games for students, as well as materials for educators to download and integrate into their classroom curriculum.

And the interview with Buzz Aldrin is priceless.

No, the title of this post isn't a reference to the velocity of our Kerouacian prose -- it's what you could be doing if you took a train between Paris, Brussels, Amsterdam and Cologne:

 The first commercial application of the European Space Agency (ESA) “Broadband on Trains” initiative officially launched May 14 on six high-speed Thalys trains... Passengers on the trains equipped with “Thalysnet” have continuous Internet connectivity while traveling at 300 km/h via a satellite 36,000 km above the trains.

The satellite link uses a low profile tracking antenna on the train to provide a two-way connection to the Ku-band satellite system and a hub station connected to the Internet backbone. Terrestrial wireless is used to maintain a connection when the train is traveling through tunnels. The total bandwidth from the satellite shared among users on the train is 2 Mbps down and 512 Kbps up. Bandwidth across all trains in the fleet is allocated on demand according to the usage level.

The tracking antenna truly is low-profile. If a train passes you at high speed, you'd be hard pressed to see the little nub whizzing by you:

The ESA initiative to bring broadband to trains started nearly two and a half years ago; as of May of this year, Thalysnet is officially and commercially available to train passengers: 

Thalysnet... was developed by a consortium lead by Nokia Siemens Networks, which combines satellite communications with conventional wireless data technologies to provide a continuous Internet connection on board trains travelling across national borders at 300 km/h. One of the companies in the consortium is the UK-based 21Net, which carried out a pilot project in 2005 under the European Space Agency's Broadband to Trains initiative.

21Net worked with leading railway operators such as RENFE (Spain) and SNCF (France), along with Thalys, to develop a solution combining bi-directional satellite communications with terrestrial wireless technologies.

With soaring gas prices leading to an increase in public transport usage here in the US, could an American equivalent of Thalysnet be far behind? 

First it was soaring gas prices, then the cost of food – now it appears that the price of natural gas will surge fast.

The consequence? The cost of heating your home will be a lot more expensive next winter (especially if you're in Wisconsin). What to do?

Well, if you're in Iceland, just dig a hole. An amazing 90% of homes are heated with geothermal energy. Of course, with my luck, I picked this unheated, sod-roofed backpackers hostel/shack (highly-recommended, btw) on my recent stay in Iceland. Chilly nights.

But, if you're still States-side, the geothermal option probably won't work. So beyond simple conservation, let's start by finding a simple and energy-free way to heat our water – the sun!

Way back in 1984, Mother Earth News brought us the plans for building an integral passive solar water heater (IPSWH):

For the do-it-yourselfer searching for an inexpensive, easy-to-build solar water-heating system, the integral passive solar water heater (IPSWH, pronounced ipswah ) is a dream come true. All you need to get going on this down-to-earth water warmer is a discarded electric water heater tank rescued from the local dump, a homemade plywood box to house it in, a can of flat black paint, a sheet or two of used window glass or clear plastic, a few common plumbing fittings and some pipe and insulation. Combine all that with some spare hours of satisfying sawing, hammering and wrench-turning, and you'll have an ongoing supply of hot water provided virtually free from that friendly furnace in the sky.

The article gives a good how-to on the building process, and a fairly exhaustive explanation on the different types of active and passive solar water heaters. And just three months ago came Mother Earth's modern update. Among the findings: the solar water heater payoff could be dramatic, especially considering rising energy costs:

Solar water-heating systems have minimal—sometimes zero—operating costs, and maintenance costs only about $2 per month. When all costs for purchase, installation, maintenance and operation are taken into account, a solar water heater usually pulls even with an electric heater after just eight and a half years, and equals a gas heater in about 15 years. From then on, through the expected 40-year life of the solar system, you've got FREE hot water.

When you're ready to roll-up your sleeves, Instructables has the how-to pictures and directions. Build it Solar posts some other plans, including a pretty wild idea to use the energy from composting to heat water. And this enviro-solution is just a damn good excuse to throw a party (instructions are available here).

But, despite all the fun ideas, this is one of the few DIY projects that I encourage you to get some help. If you really want to save some money, reduce your CO2 output, and keep the system cooking for 40+ years, I'd skip the bottles and buy a system.

Have a great weekend!

We'll miss Harvey Korman, the actor/comedian who passed away recently. He was the voice of The Great Gazoo on The Flintstones.

We blogged about the character before, although we got the name wrong (oops).

As reported in the Wall Street Journal and Aviation Week, among other major publications, China is importing "ITAR-free" satellites and other space technologies from a European company, thereby evading U.S. export controls that are intended to safeguard our national security. China is also developing its Long March 5 rocket that will be capable not only of delivering people to the moon, but also landing nuclear payloads anywhere in the United States.

That's from a Senate Hearing (webcast) earlier this month. For those unfamiliar, ITAR (International Traffic in Arms Regulations) is a set of regulations that prohibit Americans or American companies from sharing or selling information or materials pertaining to defense and military related technologies. There is a balance to be found here: since lots of American technology is adapted from military technology, it can be difficult to sell non-militay products internationally (like satellite launch vehicles) and to collaborate with International partners on products that include proprietary military technology. Wikipedia does a nice job describing the controversy:

There is an open debate between the Department of State and the industries and academia regulated by ITAR concerning how harmful the regulatory restrictions are for U.S. businesses and higher education institutions. The Department of State insists that ITAR has limited effect and provides a security benefit to the nation that these sectors must bear. Every year the Department of State can cite multiple arrests of ITAR violators by U.S. Immigration and Customs Enforcement agents. However, many companies and institutions within the affected areas argue that ITAR is stifling U.S. trade and science. Companies argue that ITAR is a significant trade barrier that acts as a substantial negative subsidy, weakening U.S. industries' ability to compete [4]. U.S. companies point to announcements in Europe by EADS and Alcatel promoting their "ITAR-free" satellites and defense items.[5] Higher education institutions argue that ITAR prevents the best international students from studying and contributing in the U.S. and prevents cooperation on international scientific projects.

Currently, officials at the Department of State dismiss the burden on industry and educational institutions as minor compared to the security provided by ITAR. They also view the announcements of "ITAR-free" items as anecdotal and not systemic.

Now that we've got the background, back to the Senate hearing: China is importing "ITAR-free" space technology from European countries. It's a perfect example of the controversy: the U.S., worried about national security implications, limits technology sharing/selling to China. But, when Europe fills the gap, it just cuts at traditional U.S. superiority in the space/satellite technology market. Just this Tuesday, with the Berlin Air Show as the backdrop, OHB presented the European Space Agency with a plan (subscription-only) to develop ITAR-free spacecraft:

BERLIN — European governments have agreed that a new commercial telecommunications satellite design they are financing will permit customers to order a version without U.S.-built parts covered by the now-infamous U.S. technology export regime known as ITAR, government and industry officials said here May 27.

Officials said that while the first Small GEO platform, being tailored for Spanish satellite-fleet operator Hispasat, will feature U.S. parts, future versions that are not subject to ITAR, or U.S. International Traffic in Arms Regulations, will be available upon customer request. ITAR rules treat satellites and many of their components as weapons for export-control purposes and allow the U.S. State Department to veto those who can purchase the satellite, and where it can be launched from.

"Customers will be able to choose which version they want, although the ITAR-free version will be a little bit more expensive," said Manfred Fuchs, founder and president of OHB System of Bremen, Germany, which is prime contractor for the Small GEO program.

Led by Germany and Spain, nine European Space Agency (ESA) governments — France notably is absent — are contributing 190 million euros ($299 million) to design the Small GEO and develop the first model. Hispasat is the first customer and has agreed to spend more than 50 million euros of its own to pay for the satellite's launch and insurance. The first Small GEO model, called Hispasat AG1, will be fitted with a Ku- and Ka-band telecommunications payload and is scheduled for launch in 2012. OHB and Hispasat signed a preliminary contract for the satellite May 27 here at the Berlin air show, ILA 2008. A final construction contract is expected to follow in September.

Industry and government officials said OHB presented ESA with a list of components and technologies that would be needed for the Small GEO platform and asked which were available in Europe. All major subsystems will be built by European contractors. But several individual components will be purchased in the United States.

"It was more a matter of cost and time than anything else," a European industry official involved in the selection said. "This is a new satellite design and we already have enough challenges without adding the complication of making it ITAR-free from the outset."

If you've been in the satcom business for a while, you remember Loral's problems with selling satellite technology to China about 10 years ago. The story made the front page of the New York Times 10 years ago:

The documents paint a fascinating portrait of the intense struggles surrounding Mr. Clinton last February as he weighed whether to allow the satellite launching and ignore the pleas of prosecutors and the probable outrage from some in Congress.

A top State Department official had warned White House staff members that the satellite company, Loral Space and Communications, engaged in ''unlawful'' and ''criminal'' activity by providing valuable help to the Chinese rocket program.

And the chairman of the company, Bernard L. Schwartz, combed a White House dinner on Feb. 5, looking for Samuel R. Berger, the national security adviser, to plead for a decision on the satellite launching, a decision worth tens of millions of dollars to the company.

As it all played out, with the company arguing it needed an immediate decision, the senior White House staff were concluding that the President's broader strategy of engaging China should not be endangered by blocking the launching.

The impact of that scandal was far-reaching and still affects how satellite technology is exported -- or not.  The spacecraft in question, Chinasat 8, was never delivered. What ever became of it? Space Systems/Loral sold it to Bermuda-based ProtoStar, modified it and just shipped it to Kourou for launch next month:

"Space Systems/Loral has been able to deliver a satellite customized to our requirements in a timely and professional manner," said Philip Father, chief executive officer of ProtoStar. "We have worked closely with SS/L throughout this project and are very impressed with the passion and commitment of all the engineers and technicians who have been involved."

The satellite, which was designed to meet the needs of both emerging and existing direct-to-home (DTH) operators in the Asian market as well as other broadband communication needs in the region, was completed for ProtoStar less than 17 months after the contract was signed. It is the first in a fleet of multiple satellites ProtoStar plans to launch that will enable its in-country partners to offer advanced satellite television services and powerful two-way broadband Internet access.
 
"ProtoStar I is the third satellite that SS/L has shipped for launch this year," said John Celli, president and chief operating officer of Space Systems/Loral. "It is rewarding to see the tangible evidence of our ability to deliver within commercial schedule constraints and to help our customers meet business plan requirements."

Space Systems/Loral was able to deliver the satellite in just over a year because the project involved modifications to an existing satellite, which ProtoStar purchased from its previous owner. SS/L then tailored the spacecraft to meet the defined power and footprint/coverage requirements of ProtoStar’s customers.

Now we read of the Protostar-1 satellite is not fully coordinated in Asia, causing quite a bit of friction, via Satellite Finance (subscription):

Confusion has broken out in the Asian satellite industry as Protostar-1 nears its launch at the end of June. Other Asian operators have expressed fears that Protostar-1 has not been properly configured to avoid interfering with the signals of other satellites close to its orbital slot at 98.5° East.

Speaking to SatelliteFinance, Peter Jackson, CEO of AsiaSat, said: "The Ku band is an issue, but it's the C-Band on the Protostar satellite that's going to be the real problem, it is going to interfere with a number of satellites. I know that the Chinese national operator has a problem because they are only a half a degree away with Chinasat 22, and Thuraya has a problem because they have a satellite right at 98.5°. New Skies will have issues as well."

Protostar is understood to be launching the satellite to the orbital slot belonging to Singapore. The Chinese Radio Regulatory Department has written to the Infocomm Development Authority in Singapore to express its concerns.

Jackson said that AsiaSat has had contact with Protostar over the issue, but that they have not been able to come to any definitive understanding on the matter. "When AsiaSat 4 launched we had to make changes to accommodate Thaicom, it's just the way it works," he said. "I'd be very surprised if Singapore allows them launch as it stands. I know that if it were Hong Kong that was in the same position it would definitely not allow it."

Protostar could not be reached for comment on the issue. Protostar-1 is an SS/L built satellite with 16 Ku band transponders and 36 C-Band transponders, and its primary purpose is to provide capacity for DTH platforms in Asia.

This should be interesting. The co-passenger for next month's launch is expected to be BADR-6 for Arabsat.
