Bad weather on Monday forced SpaceX to postpone the latest launch of its massive prototype Starship rocket, key to founder Elon Musk's dreams of colonizing Mars and NASA's plans to return astronauts to the moon.

SpaceX is now aiming to launch its Starship Flight 10 test mission on Monday (Aug. 25) at 7:30 p.m. EDT (2330 GMT) after a one-day delay.

In space, Starship will attempt to deploy mock Starlink satellites and reignite an engine along its suborbital path around the globe. Atmospheric reentry over the Indian Ocean will test its exterior steering flaps and an array of experimental heat shield tiles as the ship blazes through intense friction and heat.
