On Feb. 3rd, astronauts onboard the International Space Station will hurl an empty spacesuit overboard.
The spacesuit is the satellite -- SuitSat for short.
"Some Russian partners in the ISS program had an idea: Maybe we can turn old spacesuits into useful satellites," explains Frank Bauer of NASA's Goddard Space Flight Center.
Scientsits have equipped an outdated Russian Orlon spacesuit with three batteries, a radio transmitter, and internal sensors to measure temperature and battery power. As it circles Earth, it will transmit its condition to the ground.
To listen to SuitSat, all you will need is a big antenna and a radio receiver that you can tune to 145.990 MHz FM. "A police band scanner or a hand-talkie ham radio would work just fine," added Bauer.

I've uploaded on Flickr the images i took at the retrospective dedicated to Antwerp-based artist Panamarenko. Funky aeroplanes, air balloons, inflatable vehicles, flying saucers, weird cars and backpacks that Daedalus could have engineered...
Extremes of temperature can cause small cracks to open in the superstructure of spacecraft, as can impacts by micrometeroids. Cracks build up, weakening the spacecraft until a catastrophic failure becomes inevitable.
To replicate the human process of healing small cracks before they can open up into anything more serious, the team replaced a few percent of the fibres running through a resinous composite material with hollow fibres containing adhesive materials. Ironically, to make the material self-repairable, the hollow fibres had to be made of an easily breakable substance: glass. "When damage occurs, the fibres must break easily otherwise they cannot release the liquids to fill the cracks and perform the repair," says Christopher Semprimoschnig, at the European Space Technology Research Centre.
In the airless environment of space, the mechanical "veins" have to be filled with resin and a hardener that leak out and mix when the fibres are broken. Both must be runny enough to fill the cracks quickly and harden before it evaporates.
"We have taken the first step but there is at least a decade to go before this technology finds its way onto a spacecraft," says Semprimoschnig.

An "hyperspace" engine that could make interstellar space travel a reality by flying into other dimensions is being investigated by the US government.
The hypothetical device could potentially allow a spacecraft to travel to Mars in three hours and journey to a star 11 light years away in just 80 days.
The engine would create an intense magnetic field that, according to ideas developed by Burkhard Heim in the 1950s, would produce a gravitational field and result in thrust for a spacecraft.
Also, if a large enough magnetic field was created, the craft would slip into a different dimension, where the speed of light is faster. Switching off the magnetic field would result in the engine reappearing in our current dimension.
The US air force has expressed an interest in the idea and scientists working for the American Department of Energy - which has a device known as the Z Machine that could generate the kind of magnetic fields required to drive the engine - say they may carry out a test if the theory withstands further scrutiny.
Professor Jochem Hauser believes that a working engine could be tested in about five years.
"But this thing is not around the corner; we first have to prove the basic science is correct and there are quite a few physicists who have a different opinion," warned the scientist.
The project is the first step towards discovering whether mankind can survive for generations in space and establish permanent homes elsewhere in the solar system.
"Genes are prone to change in increased and lowered gravity. While on earth it is possible to increase gravity by spinning the flies in a centrifuge, it is much harder to reduce it. The only place to do that is in space," explains the scientist.
The first generation of flies will be launched as eggs before hatching on the International Space Station.
Scientists at the space agency have constructed a special insect habitat where the flies (normal ones but also some mutants who do not sense gravity) will live and where they can be watched by 24 digital cameras using computer tracking normally employed by the police to follow suspects.
The flies will then be frozen before being sent back to earth, where the researchers can analyse which genes have become more active or less active while in orbit.
Scientists believe that if the genetic changes from space travel accumulate from generation to generation, then settlers on other planets may kickstart another round of human evolution.

The video game would be used for the training of counter space tactics, techniques, and procedures (TTPs). The game environment should recreate four key tasks: detect, identify, track, and disrupt activities from space vehicles.
The environment will need to have object models to simulate interactions between satellites and ground stations, model track data, display raw sensor data, and have the capability for multiple players to participate and to provide command and control and other tactical and operational information and interaction to the game.
