Launching rockets into space is a dangerous, risky task for everyone. Making NASA makes things even more complicated, so NASA has some pretty strict guidelines on how to prepare for takeoff when your own astronauts fly into space.
One of the big rules of NASA is that the rockets that do the pushing must be refueled before the astronauts climb aboard. It is a safety precaution to prevent accidents during the refueling process that could lead to injury or even death. NASA takes this very seriously. Well, for the first time ever, NASA could relax their requirements just a little bit because of SpaceX.
In a new blog post, NASA reveals that it has reached an agreement with SpaceX that would make it possible for corporate rockets to be fueled with the crew already aboard. SpaceX has been doing things this way for some time, and the company's rockets are usually refueled for less than an hour before they fly into space. That would not usually work well with NASA, but the administration gives SpaceX a chance to prove it's safe.
Here 's how NASA sees it all:
If all goes according to plan, more. Www.components.oerlikontextile.com/…/tabid-1848/ The Competitive OVERRAP Pressure Vessels from Falcon 9,. known as COPVs, helium is loaded onto the launch pad prior to the arrival of the astronaut and checked for stable configuration. The astronauts will then board the spacecraft about two hours before launch when the launch system is in a dormant state. After the ground crews leave the launch pad, the takeoff systems are activated approximately 38 minutes before takeoff, just before fuel starts. SpaceX startup controllers then charge kerosene and compressed liquid oxygen in rocket levels about 35 minutes before launch.
However, NASA is not prepared to simply give SpaceX the ability to do things this way without proving that this is possible. The tentative agreement is based on the ability of SpaceX to demonstrate that refueling the missile is safe after loading the crew, and it will have to complete five test runs of the process before NASA will involve its astronauts.
Of course, the first order from SpaceX is actually that its manned rocket configuration is ready, and that takes some time.
