The final countdown for the space shuttle Endeavour
In short: As the STS-134 mission approaches, a six-member crew has arrived at Kennedy Space Center. This is not just any flight; it is the shuttle's final journey to the International Space Station, carrying a massive scientific payload and marking the end of an era in space exploration.
The crew of the space shuttle Endeavour, commanded by veteran astronaut Mark Kelly, recently arrived at NASA's Kennedy Space Center in Florida. To undertake their concluding launch preparations and a dress rehearsal, the six-person crew departed from their Houston headquarters situated by the Johnson Space Center. This period includes the Terminal Countdown Demonstration, a traditional practice session essential to every shuttle flight, and specialized training where pilot Greg H. Johnson and Kelly practice shuttle landing techniques using a modified Gulfstream jet. The crew landed their T-38 aircraft in successive groups from 5:07 p.m. to 5:24 p.m. EDT. This early arrival from Houston preceded their scheduled training period.
The STS-134 mission carries significant scientific and logistical weight. A primary objective is the delivery of the Alpha Magnetic Spectrometer, a $1.5 billion astrophysics experiment, to the International Space Station. Alongside this massive instrument, the shuttle will transport various spare supplies. The mission profile is intensive, with the crew planning four separate spacewalks to perform upgrades to the station during their two-week stay. The mission's duration is expected to last approximately two weeks. During this time, the crew will work to enhance the station's capabilities.
This mission represents a poignant moment in NASA's history. Following Endeavour's flight, NASA plans only one more shuttle mission: the STS-135 flight of the shuttle Atlantis, scheduled for June. The retirement of the shuttle orbiters to museums is part of a broader strategic transition. NASA is moving away from the shuttle program to focus on a new era of exploration, specifically aimed at sending astronauts to Mars and an asteroid. The STS-135 mission of Atlantis is the only remaining flight in the program. Once complete, the orbiters will be moved to museums.
