The Automated Transfer Vehicle (ATV) Jules Verne will undock from the International Space Station (ISS) on September 5th to begin three weeks of autonomous flight, setting it up for a suicidal re-entry on September 29th. The ATV has been loaded with refuse and unwanted equipment from the ISS set to burn up in the Earth's upper atmosphere marking the end of the life of Europe's most advanced space vehicle. To record the event, both NASA and the European Space Agency will be photographing and videoing the descent…

During a Russian weather observation campaign, cosmonaut Oleg Kononenko took photographs above the South Ossetia region of Georgia soon after the Russian military action in the area on August 9th. According to NASA's ISS Daily Report, Kononenko was monitoring the "after-effects of border conflict operations in the Caucasus" and his orders from Moscow instructed him to carry out this task for humanitarian reasons. Some sources are suspicious of this possible orbital reconnaissance opportunity, citing that the 1998 ISS international agreement enforces the rule that the space station can only be used for civilian activities. However, NASA has stated that the Russian space agency Roscosmos admitted to the photography request, saying that the images were required to monitor serious water management issues and not intended for military purposes…

Could this be the first space-borne computer virus ever discovered? It would appear that the International Space Station, orbiting at over 330 km (180 miles) above the planet, is not immune to software problems more commonly associated with computers down here on Earth. Over the last few days, astronauts on board the ISS have been tracking down a fairly benign gaming worm used by hackers to gather personal information. Although this type of virus is not considered a threat to space station operations, it does raise some questions about how the virus got up there and why the station's computers were not protected.

The conflict between Georgia and Russia over the disputed region of South Ossetia may have huge consequences for NASA's ability to send astronauts to the International Space Station in the future. The US has criticised the Russian military action, prompting concerns for the future NASA use of the Russian Soyuz space vehicle. This comes at a particularly critical time, as concerns were already high due to the Shuttle decommissioning in 2010. The US is only allowed to use Soyuz up until 2011 as that is when the exemption from the Iran Non-Proliferation Act runs out. If US-Russian relations turn even more sour, an extension to the exemption may not be allowed, freezing the US out of any involvement with routine manned access into space. US Senator Bill Nelson (Democrat), an outspoken critic of the government's funding of the US space program, has brought these concerns to light blaming the Bush administration for an over reliance on Russia for future space access…

NASA Administrator Michael Griffin has announced his intentions to send an advanced spaceship propulsion prototype to the International Space Station for advanced testing. The Variable Specific Impulse Magnetoplasma Rocket (Vasimir) is currently in an experimental phase, but Griffin hopes that a scale model will be ready for one of the remaining Shuttle-ISS missions before 2010. The Vasimir concept bridges the gap between conventional (fuel hungry, high thrust) rockets and economical (fuel efficient, low-thrust) ion engines. Vasimir achieves this by using an ingenious method of ionizing and heating a neutral gas fuel…

A huge piece of space debris, weighing 1400 lb (635 kg) and the size of two refrigerators, is gradually falling to Earth, giving observers on the ground a great opportunity to see it. The junk was jettisoned from the International Space Station (ISS) in 2007 and it is expected to re-enter the atmosphere later this year or early 2009. The Early Ammonia Servicer (EAS) was dropped from the ISS after a seven hour spacewalk and pushed in the opposite direction of the space station's orbit shortly before a re-boost by a Soyuz resupply vehicle. This ensured the EAS would pose no danger to the ISS or crew on future orbits. Now the container is beginning its final few months in space and the bets are on as to where it will crash to Earth…

The International Space Station (ISS) is the jewel in the crown of human ingenuity and a testament to the incredible engineering mankind is capable of. The modular human outpost began construction in 1998 and it is hoped the final configuration will be complete by 2010. Apart from orbiting the Earth and the occasional re-boost by the docked Automated Transport Vehicle (ATV) "Jules Verne," the ISS is going nowhere in a hurry. But wait a minute, isn't that what the ISS is all about? Isn't it simply an orbital science outpost? Well it is, but could it be something a bit more dynamic? Some critics cite the ISS as the most expensive waste of time the international collaboration of space agencies have ever been committed to; after all, who needs more zero-G experiments?

Solution: Attach a rocket and a steerage system and behold, we have a huge interplanetary transport vehicle, capable of travelling to the Moon and possibly to Mars. Who needs the Constellation Program anyway…

Two cosmonauts at the International Space Station conducted a spacewalk on Thursday and performed the delicate operation of removing an explosive bolt from the Soyuz capsule attached to the station. Ten explosive bolts in all on the Soyuz break the connections between the spacecraft's crew capsule and its propulsion module during descent back to Earth. Engineers suspect one bad bolt delayed the compartment's jettison during landings in October 2007 and April 2008, leading to steep, high-G descents, causing the capsule to land off-course and hit the ground harder than it should. Sergei Volkov and Oleg Kononenko removed the bolt located in the same spot as the ones diagnosed as being faulty on the other capsules. They placed it inside a blast-proof canister, which will be returned home aboard the Soyuz when the crew completes its mission in October.

Explosive bolts that help detach the Russian Soyuz capsule from the International Space Station may be the source of the problems the spacecraft has encountered during the last two landings. Investigative space journalist and Jim Oberg at MSNBC, who is one of the best experts on the inner workings of the Russian space program recently wrote a very interesting article detailing Russian engineers' plans to fix the problem: have two Russian cosmonauts conduct a spacewalk on July 10 to remove one of the explosive bolts and bring it inside the space station. The bolts, Oberg says, packs twice the explosive force of an M-80 firecracker when ignited, and the cosmonauts will be handling the bolts directly during what will be a very delicate, if not dramatic, operation.

Last week's record re-boost from ESA's Automated Transfer Vehicle (ATV) pushed the International Space Station 7 kilometres (4.3 miles) higher to an orbit of 345 kilometres (214 miles) above Earth. This was the second re-boost carried out by the ATV, a mission (dubbed "Jules Verne") that has surpassed all expectations. In fact, the ATV has not only passed each and every mission objective perfectly, it has gone above and beyond the call of duty…

Always a beautiful sight, the space shuttle Discovery touched down safely at 11:15 a.m. EDT, on Saturday, June 14, 2008, at the Kennedy Space Center in Florida. During the 13-day mission, Discovery and the crew of STS-124 delivered the new component Kibo, the Japanese Experiment Module, to the International Space Station. Mission managers say Discovery looks to be in good shape following the mission, and the crew is doing well, too. Even Garrett Reisman, who spent over 90 days on the ISS, joined the rest of the crew in walking around on the runway and surveying the shuttle. After a successful mission, its always fun to look back at some of the great images, so here's a few…

Space is a very dangerous place to be, whether you're a human or a transistor. Highly energetic particles may hit astronauts, causing damage to their DNA, but as computers become more and more powerful (yet more and more sensitive); the hazards to unprotected circuitry are increasing. There are many examples of satellites and robotic space missions getting hit by energetic particles, sometimes with crippling results. Not only are millions of dollars at stake, lives are put at risk too. Now, using a new technique and material, Northwestern University scientists have developed a new type of transistor with a twist and it is currently being tested on the International Space Station…

This could be a bit of a tricky (and amusing) situation for astronauts on board the International Space Station (ISS). Space Shuttle Discovery astronaut Mark Kelly mentioned a minor technicality with the new Kibo laboratory during an in flight interview last Friday: It might be too spacious. Surely this is a good thing right? It is, and it isn't. On the one hand the lab provides a large volume for four astronauts to work in comfortably, but on the other hand, if you get stuck in the middle, you may not be able to reach the sides. This could result in a rather frustrating situation where one of the astronauts may become "stranded" in zero-G…

The crew of the STS-124 mission has been busy installing equipment on the International Space Station, fixing a toilet, and trying out the latest robotic arm that's part of the shiny new Kibo module. The image above shows some of the new additions to the station, which just keeps growing in size with every mission. The mass of modules shown are: the Japanese Pressurized Module (left), the Japanese Logistics Module (top center), the Harmony node (center), the Destiny laboratory (right) of the ISS, and the forward section of Space Shuttle Discovery that is docked to the station.

It has been a very good day for the crew on board the International Space Station. Not only has the brand new Japanese Kibo science laboratory been activated, much to the crew's relief, the faulty toilet has also been fixed. Russian flight engineer Oleg Kononenko was able to replace the broken urine collection pump in a 2 hour repair job yesterday (Wednesday) and specialists in Moscow checked his work to verify it was working fine. Although this may sound like a bit of minor news, it was make-or-break time for the ISS as if the repair was unsuccessful, this may have seriously hindered the manned presence on the station (and besides, we haven't even had time to play with Kibo yet!)…

The brand new Japanese science laboratory was attached to the International Space Station today (Tuesday). Space Shuttle Discovery's STS-124 mission launched on May 31st (Saturday) has quickly gotten down to business, unloading the huge 11.2 meter-long lab using the station's robotic arm. This is the second component of Kibo (Japanese for "Hope") to be attached to the station, the first was a logistics module sent to the station by Endeavour in March. The third and final part of the lab, a facility that will allow outdoor experiments be exposed to space, will be delivered some time next year. The lab will be "switched on" and ready for occupation tomorrow (Wednesday) at 20:52 GMT.

Countdown for the next space shuttle mission, STS-124 will begin today, Wednesday May 28 at 3:00 pm EDT. Launch is scheduled for Saturday, May 31 at 5:02 pm EDT. The mission will deliver Japan's Kibo pressurized module to the station, as well as some last minute, very important equipment: parts to repair a balky toilet on board the space station. The pump that separates the solids from the gas wastes for the toilet has been working only sporadically. The replacement parts are being flown in from Russia today, hand-carried in a diplomatic pouch, and will be added to the payload on board space shuttle Discovery. "Clearly, having a working toilet is a priority for us," said NASA's Scott Higginbotham, mission manager in the International Space Station and Spacecraft Processing Directorate. STS-124 is the 123rd flight of the space shuttle, the 26th flight to the station and the 35th flight for space shuttle Discovery.

The next few evenings will provide excellent opportunities for observing the International Space Station in the night skies above both Europe and North America. Beginning this evening, May 21 through May 23 the ISS will pass over from two to four times per night, depending on your location. Because of the station's current orientation and flight path, it will be highlighted almost constantly by sunlight as it flies over these continents, and thus visible to Earthlings below. If you've never had the opportunity to see the space station fly over your backyard, this is a great chance to do so, given your specific area is free from cloud cover. And for those of you that have seen the ISS before, you know what a spectacular (and sometimes spine-tingling) sight it is. It's unusual to get such a clear view of the ISS across such a wide spectrum of countries. And how, you ask, can you find out when the station will be flying over your house?

Right now, the crews on board the International Space Station consist of three people. But by late next year, the crew size will grow to six. That means more food, more water and ultimately more waste. But NASA has been working on a recycling system to transform urine and other liquid wastes into water that can be used in space for drinking, food preparation and washing. Agency officials say the water from the system will be cleaner than U.S. tap water. Not only does this help manage wastes on board the station, but its also a cost-saving measure. Water is heavy and launching it on board the shuttle or Progress re-supply ship is expensive.

On Tuesday, to help out with the 50-year anniversary of the National Aeronautics and Space Administration, clips from 100 hours of restored archive footage of NASA missions were made public. At the screening, John Glenn, America's first astronaut to orbit the Earth, watched the clips and had time to reminisce over the administration's "Glory Years". He also had a very strong message for the policy makers: Extend the Shuttle program and re-commit to a long-term investment in the International Space Station. As a former Marine, Mercury astronaut, pilot and US senator, that's a hard message to ignore…

For the first time since docking with the International Space Station (ISS) on April 3rd, the Automated Transfer Vehicle (ATV) "Jules Verne" has been awoken and instructed to carry out an impressive task: push the ISS to a higher orbit. The robotic supply vessel, currently attached to the station's Zvezda module carried out a 12 minute 20 second burn of its main engines. This is the first time an ESA spaceship has carried out such a task and it appears to have performed flawlessly, lifting the 280 tonne station 4.5 km (2.8 miles) to a new altitude of 342 km (213 miles). In true ESA style, they've even released a cool video simulation of the event…

Now the dust has settled news sources appear to be coherently reporting the events that unfolded early Saturday morning. As several readers have shown concern that reporting on the Soyuz ballistic re-entry makes us opposed to Russian efforts in space, I hope these points clearly show that this is not the case. In actuality, without the Russian Soyuz fleet of personnel/cargo supply spacecraft, much of the international community's plans for space would be scuppered. So, what do we know happened after the Soyuz descent capsule undocked from the space station in the early hours of Saturday?

First, Russian space officials tried to cover up the emergency landing of the Soyuz descent capsule on Saturday. Then they blamed the crew for changing their flight plan without communicating with mission control. Compounding the problem, an official cited a bad omen as a contributing factor to the hard landing. Within a couple of days, the truth behind the Soyuz "ballistic re-entry" began to come to light. Today, even more shocking revelations are being reported, including how the escape hatch nearly failed during the uncontrolled, fiery re-entry…

The facts behind the "ballistic re-entry" of the Soyuz descent capsule are beginning to come to light. According to several news sources, after the capsule made an unusual steep descent through the atmosphere, putting it at least 400km off-target, the parachute was set alight causing a small bush fire on landing. The crew, who had to wait upside down, reported smoke inside the capsule. Although the Russian space agency overseeing the rescue helicopters reported that the crew were safely on the ground, in reality they were struggling to find their location. Russian cosmonaut Yuri Malenchenko had to unhook himself from the askew craft, get outside and use a satellite phone to confirm they were alive and well. Tough questions are now being asked as to why mission control lost track of the capsule in the first place and why they covered up the reality of the landing till so long after the event…
