SpaceX introduces team to test Dragon for manned space flight

Recently, SpaceX “announced it has assembled a team of independent experts to help the company create a safe spacecraft for NASA astronauts.”

And, one of them, Edward Lu, is on Google+:

“I’m looking forward to peeking under the hood of the SpaceX Dragon, and helping them successfully launch humans into orbit!”

More on the company’s initiatives:

The company is already building its Falcon 9 rockets and Dragon capsules to deliver cargo to the International Space Station and has a $1.6-billion contract to do just that for NASA 토이스토리2 다운로드.

SpaceX plans to send its unmanned Dragon capsule to dock with the International Space Station on April 30 from Cape Canaveral, Fla., in a demonstration flight for NASA 빠른 성경 듣기. If successful, SpaceX would be the first private company to accomplish the feat.

Now that the space shuttle is retired, SpaceX wants in on the potentially multibillion-dollar job of ferrying astronauts to and from the station 요 화경 다운로드. To do that, SpaceX needs to make sure its capsule — which is built to fit up to seven people — is safe.

The independent “safety advisory panel” is composed of leading human spaceflight safety experts:

  • Leroy Chiao, former NASA astronaut, former International Space Station commander 윈도우 8 1 다운로드.
  • G. Scott Hubbard, former director of NASA Ames Research Center, Stanford University professor of aeronautics and astronautics, sole NASA representative on the Columbia Accident Investigation Board 다운로드.
  • Dr. Richard T. Jennings, former chief of medicine for NASA Johnson Space Center, University of Texas Medical Branch professor at the Aerospace Medicine Center 다운로드.
  • Capt. Mark Kelly, former NASA astronaut, former Space Shuttle commander, retired Navy captain.
  • Edward Lu, former NASA astronaut 매드 게임즈 타이쿤.

More about SpaceX, including their manifesto: “transparency, low prices, and worldwide dominance for the future of space travel.”

 

In 2010, the second flight of Falcon 9 orbits the first operational Dragon spacecraft under the NASA COTS program, and SpaceX becomes the first private company to recover a spacecraft from Earth orbit—a feat previously only accomplished by a few nations.
