SpaceX could attempt a key demonstration for NASA during the third test flight of its towering Starship rocket, according to the federal agency. The propellant transfer demonstration would require that the rocket reach orbit as one of the demo's goals. "NASA and SpaceX are reviewing options for the demonstration to take place during an integrated flight test of Starship and the Super Heavy rocket. However, no final decisions on timing have been made," NASA spokesperson Jimi Russell said in a statement to CNBC. SpaceX CEO Elon Musk said shortly after November's flight test that hardware for a third Starship launch "should be ready to fly in 3 to 4 weeks."
