Really Rocket Science

Nice setting: a calm evening along the coast in French Guiana. Suddenly, there's a huge clap and a rocket appears on the horizon. Awesome.

That's what it's like in the Department of French Guiana. Here's the official story...

After its 6:41 p.m. liftoff from the Spaceport, the vehicle’s cryogenic upper stage was injected with the following provisional orbital parameters:
- Perigee: 249.9 km. for a target of 249.7 km.
- Apogee: 35,972 km. for a target of 35,958 km.
- Inclination:  2.00 deg. for a target of 2.00 deg.

During tonight’s launch, the Arabsat-5A satellite was deployed first during the flight sequence, being released from atop Ariane 5’s payload “stack” at 26 min. into the mission.  Produced by Astrium and Thales Alenia Space on a turnkey contract for the Arabsat telecommunications operator, the satellite had a mass at liftoff of about 4,940 kg.

Arabsat-5A carries 24 Ku-band transponders and 28 C-band transponders for telecommunications and TV broadcasting services over the Middle East and Africa.  Astrium provided the Eurostar 3000 spacecraft platform and was responsible for satellite integration, while Thales Alenia Space supplied the payload.

This mission marked another milestone in Arianespace’s 25-year relationship with the Saudi Arabia-based Arabsat telecommunications operator, which began with the launch of Arabsat 1A in 1985 on an Ariane 3 vehicle. A total of seven Arabsat satellites have been launched by Arianespace during the past 25 years.

The COMS satellite passenger was separated from Ariane 5 at 32 min. into tonight’s flight, completing this second heavy-lift mission of 2010.  The multi-purpose COMS spacecraft for South Korea’s KARI (Korea Aerospace Research Institute) is fitted with three payloads for meteorological observation, ocean surveillance and experimental broadband multimedia communications services.

Liftoff mass of the COMS Astrium-built Eurostar 3000 platform was 2,460 kg., and its communications payload came from the Electronics and Telecommunications Research Institute (ETRI) in Korea.  COMS continues a collaboration that started with Arianespace’s launch of the Kitsat A and Kitsat B scientific microsats in 1992 and 1993 for Korea’s Satellite Technology Research Center (SaTReC), and was followed by the 1999 launch of the KOREASAT 3 communications satellite for Korea Telecom.

 Yeah, the video!

Holding the new iPhone 4 can cause interference between the GSM and WiFi antennae, so naturally the Net is abuzz with this "problem." Hey, it doesn't take a rocket scientist to figure this one out.

Brilliant Scotchtape solution from Kit Eaton, and costs almost nothing, via Fast Company...

1. Get about an inch of scotch tape off the reel (that's Sellotape if you're in the U.K.).
2. Cut it carefully so that you make a rectangle something over a half-inch long and just tall enough to exceed the iPhone 4's height (about 0.4 inches should do it).
3. Align the piece of tape so that it's covering a section of the lower left metal side of the iPhone 4, some below the thin black plastic line and some above.
4. Stick it around the phone's metal edge, making sure that all of the back of the edge's metal strip is covered--you may even be able to leave the front uncovered, as it's the back where your hand will rest. The main thing is to ensure that it's unlikely that your palm will touch the metal on both sides of the black plastic line.

 
Result: Your iPhone 4's twin antennas are now insulated against skin short-circuiting in the "problem corner". You don't even have to use scotch tape--make a statement and do it in bright red electrician's tape, if you feel better for it. 

 It's about time the geniuses at 3M got some attention.

Oh, and the new iPhone? It's lovely; held one yesterday.

NASA won a Webby Award, which second-man-on-the-moon Buzz Aldrin accepted on their behalf. I love their approach: no more that five words. You've got to choose your words carefully, as Buzz did: "Humanity. Colonization. Phobos. Monolith. Mars!"

And Jake from CollegeHumor.com's "Jake and Amir," who changed his speech when he realized who he was standing next to offstage: "Holy f*cking sh*t, Buzz Aldrin!"

I think space is cool again, thanks to the general public's curiosity and fascination with space. Let's not forget the "we could use the money elsewhere" critics, as they've got a valid point.

Then there's the British metal band Iron Maiden, who opened a new tour in Texas. Yeah, they paid a visit to Johnson Space Center and got to play with the Space Shuttle Simulator.

　これまで応援していただいた皆様に感謝いたします。

　引き続き、豪州において地球に帰還したカプセルの回収作業を進めてまいります

In other words, via JAXA...

Hayabusa separated the capsule at 7:51 p.m. and reentered the atmosphere at 10:51 p.m. on June 13th, 2010 (JST).
Hayabusa was launched on May 9th, 2003 by M-V rocket and operated for approximately seven years. During its operation, JAXA was able to achieve the difficult mission including Hayabusa's sample capture attempt after its touchdown on the asteroid named Itokawa, and Hayabusa’s return to the earth overcoming many hardships. JAXA would like to appreciate every support to JAXA leading this mission to a great success.

The Hayabusa capsule has just returned to Woomera, Australia. As the next step, JAXA will move forward to the capsule recovery.

So what did it look like on the ground? Somebody from Wakayama University Institute for Education on Space was pretty excited to capture it on video, on the ground in Australia...

One of the leaders in the "Asian Space Race" suffered a loss today. The news via the BBC...

The Korea Space Launch Vehicle 1 is thought to have blown up 137 seconds after take-off, said science minister Ahn Byong-man.

The rocket lifted off from Goheung's Naro Space Centre at 1701 (0801 GMT).

But contact was lost as the rocket reached an altitude of 70 kilometres (44 miles).

"Looking from the bright flash seen on the camera mounted on the tip of the rocket, it appears [the KSLV-1] exploded in flight during the first-stage ignition," said Mr Ahn.

Pictures on South Korean television appear to show the rocket's final moments, with the cameras following a white speck on its downward trajectory into the sea.

Sure, there's media attention on the World Cup in South Africa. The latest of Adidas is entertaining (above), and Nike broke viewing records with its spot...

Shaw Direct Satellite TV will be broadcasting the the CBC's FIFA World Cup in 3D-TV throughout Canada. ESPN will be using an OC-12 fiber connection and use MPEG-4 encoding for their main feed from South Africa. This list goes on and on.

So who's at the source of all this worldwide broadcasting? Host Broadcast Services, that's who. And it's complicated. With more cameras and tech than ever before. TV Technology gives us the detail...

HBS crew at the IBC can browse the servers in the OB trucks, while also ingesting up to 18 live video feeds coming from the venues to the IBC. HBS packages the content into a fully formatted programme feed for wholesale delivery to Media Rights Licensees.

The EVS equipment tally at the HBS Production facility is 50 HD XT[2] servers, totaling 1900 hours @ 108 Mbps (DVCPro HD), plus another 1100 hours of hi-res media in an XStore[2] storage platform. 140 IPDirectors are for logging, browsing and content management. 6 XF[2] units are for removable storage. 32 Xedio Media Dispatchers are for P2 file selection, clipping and transfer.

3. IBC Johannesburg — MRL Production — this other half of the IBC comprises the studio and production facilities set up individually by each of the visiting broadcasters, as well the home broadcaster, SABC. Deemed “Media Rights Licensees”, the abbreviated form “MRL” is now the common term to describe the visiting broadcasters and those who stayed at home but nonetheless paid for the rights to rebroadcast the FIFA World Cup matches in their geographical zone.

Collectively, the MRL’s in the IBC will be making good use of 60 EVS HD XT[2] servers, 30 IPDirectors and 20 XF[2] sets of removable storage.

4. Distribution — now somewhat more complicated than it used to be due to the emergence of web and mobile video distribution pipelines in addition to the traditional terrestrial, satellite and cable outlets. Extremely fast turnaround of packaged clips is part of the system design. The HBS promise is to deliver craft edited clips for mobile devices within three minutes after the live action. 

Something to think about as you watch.

The guys at EepyBird.com are at it again. This time it's a car powered by Coke Zero and Mentos. The video was seen 2 million time in its first week.

Wired went behind the scenes for this story...

Fritz Grobe and Stephen Voltz are the guys behind the famous video of a Mentos-and-Diet Coke, Bellagio-style fountain, which they estimate has been seen by more than 120 million people. Four years later, they’re back with a rocket car powered by nothing but Mentos and Coke Zero. The video, which debuted this week, shows the duo’s efforts to set a land-speed and distance record for a vehicle powered by nothing but erupting, minty, fizzy soda.

The video was directed by Rob Cohen (director of The Fast and the Furious). Two dimensions not enough? There’s even a 3-D rocket car video you can watch on YouTube, if you have a pair of red-and-cyan 3-D glasses.

Wired sat down with Grobe and Voltz shortly after a recent performance at Maker Faire to find out how they built their 900-pound vehicle. It contains 108 2-liter bottles of Coke Zero, 648 Mentos, an elaborate-looking system of PVC pipes and pistons, and a complicated rig for dropping all those mint candies into all those bottles at the same time. In this exclusive Wired.com video, the duo explain how they made the magic happen.

More like 520 days. Six guys, locked up in a box for about a year and a half, starting 3 June 2010.

Let's see if Letterman picks up on this "top 10" list for his show. More on this mission from the ESA...

Very cool technology being developed by Ad Astra Rocket Company: using plasma engines to reach Mars in 39 days. Hammer-down: space truckin at 110,000 MPH.

Excellent piece in SpaceflightNow.com on the VASIMR engine...

The company's main project is the Variable Specific Impulse Magnetoplasma Rocket, or VASIMR, a highly-efficient space engine running on electricity and argon gas instead of conventional solid or liquid propellants.

Franklin Chang-Diaz, the project's chief architect, says the VASIMR engine is the most flight-ready high-power electric propulsion system anywhere in the world.

"It is transformational technology that we are developing," Chang-Diaz said. "It always has been my view that chemical approach to space transportation really was not going to get us very far."
 
Chemical rocket engines require spacecraft to carry all of its propellant during its mission. The VASIMR engine burns small amounts of argon gas, one of the most stable elements on the periodic table. But one of the most revolutionary features of the VASIMR design is its reliance on electricity, a renewable resource in space.

"It's very robust, but in order to get beyond the moon, and move on to Mars and beyond, we really need completely new transportation technology," Chang-Diaz said. "We view the VASIMR as the workhorse for that transportation infrastructure."

Electrically-powered plasma rockets could cut travel times for missions across the solar system. One concept championed by Chang-Diaz involves a 39-day mission to Mars, but it assumes leaps in nuclear energy production in space. 

Yeah, it works alright. Watch this engine test...

Here's a video clip about the company...

And a simulation of the trip to Mars...
