Crew Dragon will change into the primary business spacecraft to hold people to the area station

Elon Musk’s firm SpaceX is about to launch its area automobile – the Crew Dragon – with astronauts onboard for the primary time. Right here, we reply some frequent questions concerning the mission.

Why is a non-public firm launching Nasa astronauts?

Nasa has been planning at hand over the transport of crew to the Worldwide House Station (ISS) for the reason that early 2000s. After the Columbia area shuttle broke up throughout its return to Earth in 2003, the area company centered on growing a substitute spaceship that would journey to the Moon. Involving non-public companies within the switch of crew and cargo to the ISS was a needed step to afford that programme. In 2014, entrepreneur Elon Musk’s firm SpaceX and aerospace large Boeing have been introduced as winners of a Nasa contract for crew transport providers. SpaceX is launching its spacecraft first; the Crew Dragon spacecraft will raise off on Wednesday atop a Falcon 9 rocket from Florida’s Kennedy House Middle.

What’s SpaceX?

SpaceX is an American firm that gives business and authorities launch providers on its Falcon 9 and Falcon Heavy rockets. Entrepreneur Elon Musk based the corporate in 2002, with the aim of lowering area transportation prices, enabling the colonisation of Mars. SpaceX was the primary non-public firm to routinely return rocket phases to Earth beneath propulsive energy in order that they may very well be re-flown reasonably than being discarded. It has been conducting common flights of cargo to the ISS, and can now goal to start launching astronauts. Musk’s firm can be growing a much bigger spacecraft to hold people – known as Starship – which may start the method of settling Mars.

Who’s Elon Musk?

Born in South Africa, Elon Musk made greater than $160m from the sale of on-line fee service PayPal to eBay. His want to see humanity change into a real space-faring civilisation was a driving issue behind the founding of SpaceX. However he has additionally been concerned in founding quite a lot of different corporations akin to the electrical automotive producer Tesla. He additionally conceived a challenge known as Hyperloop, a high-speed transportation system utilizing pods that journey by way of a system of tubes. His vibrant persona and way of life made him the inspiration for Robert Downey Jr’s interpretation of Marvel Comics character Tony Stark. Musk isn’t any stranger to controversy: his tweets have triggered lawsuits and led to him being pressured out because the chairman of Tesla (although he remained as CEO).

Why is the launch so vital?

Because the retirement of the area shuttle in 2011, Nasa has been paying Russia tens of thousands and thousands of {dollars} to launch its astronauts on the Soyuz spacecraft. The Crew Dragon launch from Florida marks the primary launch of people from US soil in 9 years. As such, it’s seen as essential for restoring American status in human spaceflight. This may also be the primary time a non-public firm has launched astronauts into orbit.

What’s the Crew Dragon?

The Crew Dragon is the spacecraft that may transport astronauts to the ISS on Wednesday. It’s a modern evolution of the Dragon spacecraft which was constructed to ferry cargo to the orbiting outpost. The Crew Dragon is designed to hold a most of seven passengers, however Nasa flights will carry 4, with the remainder of the area taken up by provides. It’s geared up with thrusters that allow it to manoeuvre in area and can dock – or connect – to the area station beneath autonomous management. In contrast to earlier spacecraft designed for people, the crew cabin options touchscreen controls rather than bodily buttons.

Who’re the astronauts flying to area?

Bob Behnken and Doug Hurley are Nasa astronauts. They have been chosen in 2000 and have every flown to area twice on the area shuttle. They’re among the many most skilled members of Nasa’s astronaut corps and each skilled as check pilots – which has been essential for placing the brand new spacecraft by way of its paces. Hurley has spent a complete of 28 days and 11 hours in area, whereas Behnken has collected a complete of 29 days and 12 hours, together with 37 hours of spacewalking time. Each males are additionally married to astronauts.

What are the astronauts there to do?

Spacecraft designed to hold astronauts should undergo a course of that ensures they will function safely. This launch is basically the ultimate step in that validation course of. As soon as in orbit, Behnken and Hurley will check the Crew Dragon’s environmental management system, the shows and controls and the manoeuvring thrusters. They are going to monitor the autonomous docking system through the method to the area station and can change into members of the ISS crew. On the orbiting outpost, they may proceed performing assessments on the Crew Dragon together with different duties associated to the area station. When it is time to return to Earth, the Crew Dragon will parachute down into the Atlantic Ocean. The capsule and crew will then be recovered by a ship known as Go Navigator.

What if one thing goes improper through the launch?

The Crew Dragon has a built-in abort system, designed to save lots of the lives of its crew within the occasion of an emergency. If there’s an issue throughout lift-off, akin to a rocket engine cut-off, the Crew Dragon will hearth engines to propel the automobile and its occupants freed from the rocket. The capsule will then parachute all the way down to security. SpaceX efficiently carried out a check of its in-flight abort system on 19 January 2020.

What about these spacesuits?

The flight fits that Behnken and Hurley will put on within the capsule look very totally different to earlier designs. In stark distinction to the cumbersome pumpkin-coloured fits and spherical helmets acquainted from the area shuttle period, SpaceX’s fits are slimline, white, one-piece numbers with modern, 3D-printed helmets. Every one is customized made for the astronaut. In the event that they appear like one thing from a science fiction film, that is most likely as a result of their look was devised by Hollywood costume designer Jose Fernandez, who has labored on the Batman, X-Males and Thor motion pictures. However the fits additionally should be sensible; they’re designed to maintain the crew alive within the occasion of a cabin depressurisation – the place the air is misplaced from the within of the spacecraft.

What occurs subsequent?

If the Crew Dragon Demo-2 mission is profitable, SpaceX will proceed with the six “operational” missions to the ISS they’re required to fly beneath their $2.6bn contract with Nasa. Boeing holds an analogous deal, value $4.2bn, to move crew to the area station utilizing its CST-100 Starliner automobile.
