SpaceX Demo-2 astronaut mission to ISS: Every thing it is advisable to know

SpaceX Demo-2 astronaut mission to ISS: Every thing it is advisable to know

This artist’s impression exhibits Crew Dragon docking to the ISS.


In July 2011, NASA’s House Shuttle Atlantis launched from Florida to the Worldwide House Station with 4 astronauts onboard. That was the final time people traveled to area from US soil. The lengthy drought ought to quickly be over as SpaceX prepares to ship two NASA astronauts to the ISS inside a purpose-built Crew Dragon capsule on Might 27. 

The mission, generally known as Demo-2, was initially deliberate to launch in 2019, however has had its justifiable share of setbacks. With security checks on the capsule full, nonetheless, NASA and SpaceX are lastly able to fly. We have rounded up all the things it is advisable to know concerning the historic launch and when and the place you possibly can tune in.

Demo-2: The fundamentals

Demo-2 is a part of NASA’s Business Crew Program, which includes two industrial spaceflight corporations, SpaceX and Boeing, constructing and launching crew capsules designed to ferry astronauts to and from the ISS. 

SpaceX has a historical past of cargo and payload launches, however this would be the firm’s first time sending people off this rock. 

Now taking part in:
Watch this:

SpaceX set to to take its first astronauts into area


When: The launch is scheduled for Wednesday, Might 27, at 1:33 p.m. PT/4:33 p.m ET.

The place: The Falcon 9 rocket and Crew Dragon capsule will blast off from Launch Complicated 39A at NASA’s Kennedy House Middle in Florida. The historic launch pad has beforehand hosted Apollo and area shuttle missions.

Why: NASA’s Business Crew Program is aimed toward ending the US reliance on Russian spacecraft for ferrying astronauts to the ISS. NASA has been shopping for seats on Soyuz capsules because the finish of the shuttle program. 

That is additionally a part of a broader NASA push for industrial partnerships. “By encouraging trade to supply human transportation providers to and from low-Earth orbit, NASA can develop its give attention to constructing spacecraft and rockets for deep area missions,” the area company mentioned

The Crew Dragon capsule arrived on the launch web site in February 2020 for closing preparations.


The spacecraft: The SpaceX Crew Dragon is the human transportation model of the Dragon 2 capsule that has been used to hold cargo to the ISS. Whereas solely two astronauts can be on board on the finish of Might, the capsule might be configured to hold as much as seven passengers.

The rocket: SpaceX’s confirmed Falcon 9 rocket will escort Crew Dragon by way of the launch. NASA’s iconic throwback “worm” brand is emblazoned on the facet of the rocket. Falcon 9s have efficiently launched dozens of SpaceX missions.

The Falcon 9 booster is reusable and can try to land on a SpaceX droneship stationed within the Atlantic Ocean.

The crew: NASA assigned astronauts Bob Behnken and Doug Hurley to Crew Dragon again in 2018. Each have been to area on completely different shuttle missions, with Hurley flying on the ultimate flight of the area shuttle Atlantis in 2011. They can be sporting spacesuits designed in-house by SpaceX.

The objective: If SpaceX passes muster throughout Demo-2, then NASA will certify Crew Dragon for normal flights backwards and forwards to the ISS. The area company is already looking forward to this final result and has assigned astronauts to the primary Crew Dragon operational mission, which might launch earlier than the top of the 12 months if all goes nicely.

Learn how to watch the Demo-2 mission stay

NASA will present streaming protection of prelaunch, launch and ISS docking actions by way of NASA TV. 

Prelaunch protection begins at 9:15 a.m. PT on Might 27 forward of the scheduled 1:33 p.m. PT liftoff time. NASA TV will present steady protection from launch by way of docking. Crew Dragon’s arrival on the ISS is about for 8:29 a.m. PT on Thursday, Might 28. 

Making historical past

NASA is viewing the SpaceX Demo-2 mission because the daybreak of “a brand new period of human spaceflight.”  

NASA awarded the unique Business Crew Program contracts to SpaceX and Boeing in 2014 with an eye fixed to launching astronauts in 2017. Delays are widespread throughout spacecraft improvement and each SpaceX and Boeing bumped into their share of hiccups. Boeing continues to be working by way of a sequence of technical points that cropped up throughout a check flight of its Starliner car in late 2019.

SpaceX, nonetheless, efficiently accomplished the Demo-1 uncrewed spherical journey to the ISS in early 2019 and a essential in-flight abort check firstly of the 12 months, setting the stage for Demo-2. It is known as Demo-2 as a result of it is nonetheless, technically, a “demonstration” slightly than a full-fledged area mission. It marks the ultimate check for SpaceX and its Crew Dragon capsule and can permit Elon Musk’s spaceflight firm to realize human-rated certification of its spacecraft. 

Demo-2 will even be the primary time a two-person crew launched from the US because the area shuttle Columbia departed for area, on the fourth mission of this system in 1982.

Meet the astronauts  

Behnken and Hurley entered preflight quarantine on Might 13. Prelaunch quarantines had been already customary process previous to the coronavirus pandemic, however NASA will add some additional steps to the method. “Hurley and Behnken, in addition to these in direct, shut contact with the crew can be examined twice for the virus as a precaution,” NASA mentioned in a press release in Might.   

NASA astronauts Bob Behnken and Doug Hurley can be SpaceX’s first human passengers once they launch on the Demo- mission.


Bob Behnken: NASA chosen Behnken, an skilled Air Power pilot, as an astronaut in 2000. He final visited area on a shuttle mission in 2010. He has spent 708 hours in area, with 37 of these taken up by spacewalks. 

Behnken tweeted on Might 12 that he needed to get approval from his younger son earlier than launch.

Doug Hurley: Hurley, a retired Marine, was additionally chosen as an astronaut in 2000. A veteran of two area missions, he was final in orbit in 2011 on NASA’s closing shuttle mission. That provides some poetry to Hurley’s task to Demo-2. He was one of many final astronauts to launch from US soil and can be one of many first to do it once more. 

Hurley shared his personal son’s drawing of Crew Dragon in late April.

NASA has not but determined precisely how lengthy Behnken and Hurley will stay on the ISS. “They may carry out assessments on Crew Dragon along with conducting analysis and different duties with the area station crew,” mentioned NASA. The astronauts will return on Crew Dragon and splash down within the Atlantic the place they are going to be greeted by a SpaceX restoration vessel. 

Might 27 is about to mark a serious milestone in area historical past. It is not simply concerning the patriotic overtones of launching American astronauts from American soil utilizing an American rocket. 

SpaceX and NASA are set to select up a dropped thread in human spaceflight, filling the void left by the retirement of the area shuttles. We’re fairly good at sending robotic explorers to far-flung locations within the photo voltaic system, however the stakes are at all times increased when human lives are concerned. The world can be watching.
