In July 2011, NASA's Space Shuttle launched Atlantis from Florida to the International Space Station, the last time humans traveled to space from American soil. The long drought should soon be over as SpaceX prepares to send two NASA astronauts to the ISS in a purpose-built Crew Dragon capsule. This historic mission has passed a critical readiness assessment and its launch is scheduled for Wednesday, May 27.
The mission, known as Demo-2,. With NASA and SpaceX are finally ready to fly. We've collected everything you need to know about the launch and when and where to tune.
Demo-2: The basics
Demo-2 is part ofwhich involves two commercial aerospace companies, SpaceX and Boeing, that build and launch capsule capsules designed to transport astronauts to and from the ISS.
SpaceX has a history of cargo and cargo launches, but this will be the first time people have been sent off this rock.
When: The launch is scheduled for Wednesday, May 27 at 1:33 PM. PT / 4: 33 p.m. ET.
If the weather doesn't cooperate or any other factor interferes, SpaceX has reserved backup times at 12:22 PM. PT / 3: 10 p.m. ET on Saturday, May 30, or at noon PT / 3 p.m. ET on Sunday, May 31.
Where: The Falcon 9 rocket and Crew Dragon capsule will launch from Launch Complex 39A at NASA & # 39; s Kennedy Space Center in Florida. The historic launch pad has previously hosted Apollo and space shuttle missions.
Why: NASA & # 39; s Commercial Crew Program aims to end the US dependence on Russian spacecraft for transferring astronauts to the ISS. NASA has been buying seats on Soyuz capsules since the end of the shuttle program.
This is also part of a wider NASA push for commercial partnerships. "By encouraging the industry to provide human transportation services to and from Earth orbit, NASA can expand its focus on building spacecraft and rockets for deep space missions," said the space agency.
The Spacecraft: The SpaceX Crew Dragon is the human transport version of the Dragon 2 capsule used to transport cargo to the ISS. Although there will be only two astronauts on board by the end of May, the capsule can be configured to carry up to seven passengers.
The Rocket: SpaceX & # 39; s proven Falcon 9 rocket accompanies Crew Dragon during launch. NASA & # 39; s iconic throwback. Falcon 9s have successfully launched dozens of SpaceX missions.
The Falcon 9 booster is reusable and will attempt to land on a SpaceX droneship stationed in the Atlantic Ocean.
The crew: NASAin 2018. Both have been on space in various shuttle missions, with Hurley on the 2011 last flight of the space shuttle Atlantis flew. They .
The Target: If SpaceX succeeds during Demo-2, NASA Crew will certify Dragon for regular flights back and forth to the ISS. The space agency is already looking ahead to this outcome and has assignedthat could launch by the end of the year if all goes well.
NASA announced on May 22. that Demo-2 had passed the flight readiness assessment and was allowed to go.
How to see the Demo-2 mission live
NASA provides streaming coverage of pre-launch, launch and ISS docking activities via NASA TV. The timing of the launch will depend on good weather conditions, both at the launch site and in the ocean, where the crew's capsule would fall in an emergency during the launch.
Prelaunch coverage begins at 7:15 PM PT on May 27 ahead of the scheduled 13:33 PT takeoff time. NASA TV provides continuous coverage from launch to docking. Crew Dragon's arrival in the ISS is scheduled for Thursday, May 29 at 8:29 AM PT. SpaceX will also launch a webcast.
SpaceX Founder Elon Musk tweeted on May 22 that he would be watching the mission control event in Florida. Musk described the mission as the "culmination of a truly incredible amount of work by SpaceX and NASA engineers, along with the support of all countries of the International Space Station."
Discovery and Science Channel will offer a different perspective. of the procedure with its Space Launch Live event from 11am PT. The lineup includes singer Katy Perry and YouTube star and former NASA engineer Mark Rober, along with both former and current NASA astronauts. "Our live special offers both incredible launch access and expert insight from SpaceX founder and chief engineer Elon Musk and other leading aerospace professionals," Discovery said in a May 20 release.
NASA views the SpaceX Demo-2 mission as the beginning of "a new era of human spaceflight".
NASA awarded the original Commercial Crew Program contracts to SpaceX and Boeing in 2014 with a view to launching astronauts in 2017. Delays are common during the development of spacecraft and both SpaceX and Boeing have suffered their share of the hiccups. Boeing is still working on a series of.
SpaceXin early 2019 and paving the way for Demo-2. It's called Demo-2 because it's still technically a "demonstration" rather than a full-fledged space mission. It marks the final test for SpaceX and its Crew Dragon capsule and allows Elon Musk's aerospace company to achieve a human-rated certification of its spacecraft.
Demo-2 will also be the first time a two-headed crew has been launched from the United States since the space shuttle Columbia left for space, during the programme's fourth mission in 1982.
Meet the astronauts
Behnken and Hurley were preflight quarantined on May 13. Prior quarantines were standard procedure prior to the coronavirus pandemic, but NASA will add some additional steps to the process. "Hurley and Behnken, as well as those in direct and close contact with the crew, will be tested for the virus twice as a precaution," NASA said in a statement in May.
Bob Behnken: NASA selected an experienced Air Force pilot Behnken as an astronaut in 2000. He last visited space during a shuttle mission in 2010. He spent 708 hours in space, of which 37 included. through spacewalks.
Behnken tweeted on May 12 that he needed to get approval from his young son before launch.
Doug Hurley: Hurley, a retired Marine, was also selected as a veteran in 2000 of two space missions, it was last orbiting Earth in 2011 during NASA's last shuttle mission. That adds some poetry to Hurley & # 39; s dedication to Demo-2. He was one of the last astronauts to launch from American soil and will be among the first to redo it.
Hurley shared the drawing of his own son from Crew Dragon at the end of April.
NASA has not yet determined how long Behnken and Hurley remain on the ISS. "They will conduct tests on Crew Dragon in addition to conducting research and other tasks with the space station's crew," NASA said. The astronauts return on Crew Dragon and splash in the Atlantic Ocean, where they are greeted by a SpaceX salvage vessel.
May 27 marks an important milestone in space history. It's not just about the patriotic undertone of launching American astronauts from American soil with an American missile.
SpaceX and NASA will pick up a fallen thread in human spaceflight, filling the void left by the space shuttle's collapse. We are quite good at sending robot explorers to faraway places in the solar system, but the stakes are always higher when human lives are involved. The world will watch.
