SuitSat (also known as RadioSkaf, Radio Sputnik, and AMSAT-OSCAR 54) is a retired Russian Orlan spacesuit with a radio transmitter mounted on its helmet. SuitSat-1 was deployed in an ephemeral orbit around the Earth on February 3, 2006. The idea for this novel satellite was first formally discussed at an AMSAT symposium in October 2004, although the ARISS-Russia team is credited with coming up with the idea as a commemorative gesture for the 175th anniversary of the Moscow State Technical University.

SuitSat-1

In a move originally planned for December 6, 2005, SuitSat-1 entered its own independent orbit just after 23:05 UTC on February 3, 2006 when it was taken on a spacewalk from the International Space Station by Valery Tokarev and Bill McArthur as part of an unrelated EVA. Voice messages recorded by the teams involved, and by students from around the globe, were continuously broadcast in a number of languages from the SuitSat, along with telemetry data. The signal begun transmission approximately 15 minutes after SuitSat-1 was jettisoned and was relayed by equipment onboard the ISS. Anyone receiving the transmission could log an entry on the tracker at suitsat.org, detailing when and where they heard it.

However, the SuitSat-1 mission was not a total success. There were very few reports that actually confirmed the receiving of the transmission. NASA TV later announced that SuitSat ceased functioning after only two orbits due to battery failure, but there were reports suggesting that SuitSat-1 continued transmitting, though far weaker than expected.

The official designation for SuitSat is AMSAT-OSCAR 54, though it was nicknamed "Ivan Ivanovich" or "Mr. Smith". The radio transmitter used a frequency of 145.990 MHz.

The last confirmed signal report from SuitSat-1 was the report of KC7GZC on 2006-02-18, all later reports indicate that no signal was received when SuitSat-1 was due to pass over.

On 7 September, 2006, at 16:00 GMT, Suitsat re-entered the Earth's atmosphere over the Southern Ocean at 110.4° East latitude and 46.3°South longitude. It was over a point some 1400 km south-southwest of Cape Leeuwin (Augusta), Western Australia.

SuitSat-2

SuitSat-2, another spacesuit satellite, is currently in development. This satellite will contain experiments built by students and other equipment. Unlike SuitSat-1, the batteries on SuitSat-2 will be charged by solar panels, and is predicted to have a lifetime up to six months. Originally planned to launch in October 2007, the project has been delayed to a later date.

Notes

In the science fiction novel "Have Spacesuit Will Travel" by Robert A. Heinlein, the protagonist's spacesuit is named "Oscar".
