Altair (spacecraft)

Altair (spacecraft)

The Altair spacecraft, previously known as the Lunar Surface Access Module or LSAM, was the planned lander spacecraft component of NASA's cancelled Project Constellation. Astronauts would have used the spacecraft for landings on the Moon, which is intended to begin around 2019. The Altair spacecraft was planned to be used both for lunar sortie and lunar outpost missions. On February 1, 2010, U.S. President Barack Obama announced a proposal to cancel the Constellation program (except the Orion spacecraft and Altair), to be replaced with a re-scoped program, effective with the U.S. 2011 fiscal year budget.
