SpaceX has launched a new browser-based simulator that provides an idea of what it would be like to manually control the docking process of its Crew Dragon spacecraft, the first human-carrying spaceship the company has made. Crew Dragon actually docks with the International Space Station (ISS) fully autonomously, but astronauts are able to take over manual control, should that prove necessary, and this simulator provides what SpaceX says is the “actual interface” that astronauts would use in that instance.
