Toren Altair brings news that NASA and the Ad Astra Rocket Company finalized a Space Act Agreement earlier this week to test the Variable Specific Impulse Magnetoplasma Rocket (VASIMR) on the International Space Station. The agreement hinges on a series of requirements for the thruster's performance and efficiency in ground-based tests. "The primary technical objective of the project is to operate the VASIMR VF-200 engine at power levels up to 200 kW. Engine operation will be restricted to pulses of up to 10 minutes at this power level. Energy for these high-power operations will be provided by a battery system trickle-charged by the ISS power system. These tests will mark the first time that a high-power, steady-state electric thruster will be used as part of a manned spacecraft." Reader clarkes1 points out related news of a runway trial for Virgin Galactic's WhiteKnightTwo, the mothership that is designed to carry SpaceShipTwo from the ground to 50,000 feet. A very brief video shows the oddly-shaped plane moving down a runway under its own power.

Matt_dk writes to point out the upcoming tenth anniversary of the International Space Station in two days' time. "On 20 November 1998, a Russian Proton rocket lifted off from the Baikonur Cosmodrome for a historic mission: It was carrying the first module of the International Space Station ISS, named Zarya (Russian for 'dawn'). This cargo and control module, which weighs about 20 tonnes and is almost 13 meters long, provides electrical power, propulsion, flight path guidance and storage space. The launch of the module... heralded a new era in space exploration, as, for the first time ever, lasting cooperation in space was achieved between Russia, the US, Europe, Canada and Japan. Over the next ten years, many other modules were brought into orbit, and ISS developed into the largest human outpost in space. Since that time, the building blocks, transported by Russian launch vehicles or the US Space Shuttle, have expanded the ISS to the size of a soccer pitch and a current total mass of about 300 tons."

A refrigerator-sized tank of toxic ammonia, tossed from the international space station last year, is expected to hit earth tomorrow afternoon or evening. The 1,400-pound object was deliberately jettisoned — by hand — from the ISS's robot arm in July 2007. Since the time of re-entry is uncertain, so is the location. "NASA expects up to 15 pieces of the tank to survive the searing hot temperatures of re-entry, ranging in size from about 1.4 ounces (40 grams) to nearly 40 pounds (17.5 kilograms). ... [T]he largest pieces could slam into the Earth's surface at about 100 mph (161 kph). ...'If anybody found a piece of anything on the ground Monday morning, I would hope they wouldn't get too close to it,' [a NASA spokesman] said."

leighklotz writes "The international amateur satellite organization AMSAT is reporting live reception of TV images directly from the orbiting ISS via the ARISS-SSTV project. The images are said to be preparations for the upcoming visit to the ISS by Richard Garriot (W5KWQ), which will provide images from space as part of the Windows on Earth project."

Toren Altair writes "Soyuz TMA-13 with ISS Expedition Crew 18 and Richard Garriott successfully launched from Baikonur Cosmodrome at 7:01 UT (3:01 EDT). The Soyuz capsule will dock to the ISS in two days. Garriott will return to Earth with Expedition 17 crew members, Commander Sergei Volkov and Flight Engineer Oleg Kononenko on October 23." With the extra attention on this launch, the Russians have gone out of their way to say that the return of the Soyuz vehicle will be safe, after a couple of different malfunctions in the past year. Garriott is in space partly for recreation, and partly as a promotion for his latest MMO, Tabula Rasa. He took with him a hard drive filled with information about humanity, as well as DNA sequences from Tabula Rasa players and various celebrities (including Stephen Colbert and Stephen Hawking) to 'preserve' that data in case of a disaster on Earth. Garriott will also spend time running and participating in experiments. Coverage of the Soyuz mission is ongoing at NASATV.

CR0WTR0B0T writes "Richard Garriott, AKA Lord British, will be part of three experiments on the International Space Station. 'Garriott has a ticket to the space station because he is an orbital spaceflight client of Space Adventures, the only company that provides commercial human space missions ... Garriott will be the first person in space who has had photorefractive keratectomy eye surgery. NASA has approved the PRK procedure for astronauts but has not yet been able to test its effects. Garriott will help scientists figure out if visual acuity of a PRK patient changes in orbit as inner eye pressure increases by up to 50% during space flights.' Mostly, NASA wants to know if he can heal himself or provide resurrection to the other astronauts in case the experiments goes awry."

Toren Altair writes "Space Adventures announced today that Charles Simonyi, Ph.D., intends to train with the Soyuz TMA-14 crew in preparation for a spring mission in 2009 to the International Space Station. Simonyi flew his first space mission in 2007. He would be the first space tourist to repeat the experience. Space Adventures' sixth orbital spaceflight participant, Richard Garriott, son of NASA astronaut Owen Garriott, is currently scheduled to launch to the ISS on October 12 of this year."

jerryasher writes "In a leaked memo, NASA Administrator Mike Griffin discusses 'the jihad' to prematurely terminate the Shuttle and what that means for the International Space Station. One implication: there may come a long interval when only our Russian Allies are aboard the Space Station. Add that bit of irony to your new cold war kit and then wonder why Griffin discusses why we wouldn't sabotage the Space Station, and how and why the memo got leaked in the first place."

Grant Henninger writes "Rejoice! The next time you have an extra $20 million and decide to visit the International Space Station you won't need to leave the window to tell all your friends how cool it is. The ISS now has a new Wi-Fi network, so all you'll need to do is fire up Twitterrific and announce how much better you are than your Earth-based friends."

Matt Amato writes "With the recent discussion of the ISS having to dodge some space junk, many people's attention has once again focused on the amount of stuff in orbit around our planet. What many people don't know is that USSTRATCOM tracks and publishes a list of over 13,000 objects that they currently monitor, including active/retired satellites and debris. This data is meaningless to most people, but thanks to Analytical Graphics, it has now been made accessible free of charge to anyone with a copy of Google Earth. By grabbing the KMZ, you can not only view all objects tracked in real-time, but you can also click on them to get more information on the specific satellite, including viewing its orbit trajectory. It's an excellent educational tool for the space-curious. Disclaimer: I not only work for Analytical Graphics, but I'm the one that wrote this tool as a demo."

Kligat writes "For the first time since 2003, the International Space Station has utilized the rockets on the European Space Agency's Automated Transfer Vehicle to dodge leftover remnants of a defunct satellite. The Russian Cosmos-2421 was launched in June 2006 to track Western Navy vessels and is believed by NASA to have exploded — 'likely due to a self-destruct command issued by Russian officials' according to the article — leaving 500 pieces of space debris. Ordinarily, the rockets on the ATV are used to take the ISS away from Earth's atmosphere and reduce drag. In this case, the 5-minute firing caused the ISS to move downward because it was already near the top of its acceptable range. Estimated probability of impact was 1 in 72, and an avoidance maneuver is called for if the probability is greater than 1 in 10,000. The space junk was predicted to pass the ISS within just a mile."

chrb writes "BBC News is reporting that laptops taken to the International Space Station by NASA astronauts are infected with the Gammima.AG worm. The laptops have no net connection; officials suspect the worm may have been transferred via a USB flash drive owned by an astronaut. NASA have said this isn't the first time computer viruses had travelled into space."

mknewman writes "Sen. Bill Nelson, one of NASA's biggest proponents on the Hill, is openly questioning how Russia's military intervention in Georgia will affect our access to the space station after the Shuttle is retired in 2010. Currently, NASA is able to use Soyuz vehicles for crew access and lifeboat operations thanks to an exemption from the Iran Non-Proliferation Act. The exemption expires in 2011, only one year after the Shuttle is due to head to the museums."

CheshireCatCO writes "When Cassini makes its closest approach (50 km) during the flyby of the moon Enceladus next Monday 11 August, the spacecraft will be zipping by too quickly to turn and image in the usual way. So the Cassini team will be trying something new: a 'skeet-shoot' of the surface. The spacecraft will start to spin before the closest approach to the south pole so that when the best resolution is possible, the moon will drift through the field of view slowly enough to acquire unsmeared images. Of interest are the eruption-sites on the surface that give rise to the plume extending thousands of kilometers into space and producing Saturn's E ring. This flyby will be optimized for the imaging instruments (ISS, VIMS, CIRS, and UVS) in contrast with the March flyby, which was designed for the fields-and-particles instruments."

TnGoastiiaiu submitted a space.com story that expands on coverage we've had earlier about improvements being made to the ISS to increase crew capacity. He writes "ISS gets new recycling gear that transforms human waste to drinking water. Some of the water will be used to get Oxygene, too. This way it will soon be possible to host more crew members. " Also, someone needs to smack the webmaster over there for putting a background texture behind the text. It's pretty unreadable along the left hand side of the screen.

Sallust writes "Flightglobal has an interesting article about the testing of a new electrically powered plasma engine called the Vasimir. It's being developed by former astronaut Franklin Chang-Diaz and promises to greatly reduce the time and fuel required for interplanetary journeys. According to the article: 'The Vasimir involves the injection of a gas such as hydrogen into an engine that turns it into a plasma. That plasma is then energised further using radio signals as it flows through the engine, a process controlled by electromagnetic waves from superconducting magnets. Accelerated and heated through this process the plasma is focused and directed as exhaust by a magnetic nozzle. Vasimir is many times more efficient than conventional chemical rockets and far less fuel is needed.' The developers are finalising an agreement with NASA to fit a scaled-down version of the engine to the ISS to conduct operational tests. There is also a concept video on YouTube suggesting a journey time for a manned craft to Mars on the order of 60-70 days."

Toren Altair sends us this excerpt: "Space Exploration Technologies Corp. (SpaceX) conducted the first nine engine firing of its Falcon 9 launch vehicle at its Texas Test Facility outside McGregor on July 31st. A second firing on August 1st completed a major NASA Commercial Orbital Transportation Services (COTS) milestone almost two months early. At full power, the nine engines consumed 3,200 lbs of fuel and liquid oxygen per second, and generated almost 850,000 pounds of force — four times the maximum thrust of a 747 aircraft. This marks the first firing of a Falcon 9 first stage with its full complement of nine Merlin 1C engines. Once a near term Merlin 1C fuel pump upgrade is complete, the sea level thrust will increase to 950,000 lbf, making Falcon 9 the most powerful single core vehicle in the United States. The Falcon 9 will launch SpaceX's spaceship Dragon with up to 7 humans from 2009 on." We discussed SpaceX when it won the NASA competition to provide low cost commercial transport to the ISS, and also when it launched an earlier design. Basic specs for Falcon 9 are available, as well as a more technical paper (PDF).

schliz writes "Space flight planners have unveiled a new spaceship design for a joint EU/Russian trip to the Moon. The EU will be building the crew capsule, using technology developed for the automatic cargo system used to supply the International Space Station." First one to link to decent pics (the article has none) wins undying gratitude and a warm feeling inside.

schliz writes "NASA is talking to Japan's space agency about using one of its spacecraft for servicing missions to the International Space Station, according to Japanese media reports. NASA has been considering various options to maintain its commitment to the Space Station after the Space Shuttle is retired from service in 2010. According to Japanese newspaper Yomiuri Shimbun, 'unofficial negotiations' between NASA and the Japan Aerospace Exploration Agency (Jaxa) began in February."

jmichaelg writes "Michael Benson is proposing that NASA send the ISS to the moon instead of leaving it in low earth orbit. (While we're at it, we should re-brand it as the 'International Space Ship.') He points out that it's already designed to be moved periodically to higher orbits so instead of just boosting it a few miles, strap on some ion engines and put it in orbit around the moon instead of the earth. That would provide an initial base for the astronauts going to the moon and give the ISS a purpose other than performing yet more studies on the effect of micro gravity on humans. Benson concludes: 'Let's begin the process of turning the ISS from an Earth-orbiting caterpillar into an interplanetary butterfly.'"
