"Gregory Errol Chamitoff (born 6 August 1962) is a Canadian-born American engineer and former NASA astronaut. He has been to space twice, spending 6 months aboard the ISS across Expedition 17 and 18 in 2008, and another 15 days as part of STS-134 in 2011. STS-134 was the last of Space Shuttle Endeavour which delivered the Alpha Magnetic Spectrometer and completed the US Orbital Segment.
In 2008, Chamitoff voted from outer space; he also conducted a live-from-space satellite chat with students attending school in London." - (en.wikipedia.org 17.12.2023)
