But before Starship gets off the ground, Musk has given spacefaring fans a glimpse of the hexagonal heatshield tiles that will eventually protect the craft from searing heat.
Musk explained that the hottest parts of the heatshield, glowing white in the short video above, reached a maximum temperature of around 1650 Kelvin (approx. 2,500 degrees Fahrenheit, approx. 1,375 degrees Celsius). He suggested this could withstand the extreme temperatures associated with returning to Earth, but it is slightly lower than the temperatures NASA’s Space Shuttles were built to withstand (approx. 1,500 degrees Celsius).
On March 12, the Raptor rocket engine — which will eventually help power Starship to the moon and beyond —, where SpaceX are gearing up for Starship’s first test “hops”. The hops will test the takeoff and landing capabilities of a Starship prototype, affectionately known as “Starhopper”, and the Raptor engine.
On Friday, a Twitter user, Austin Barnard, snapped photos of the Raptor engine affixed to the Starhopper for the first time. With all of the machinery in place, Musk believes the test .
