Starship Super Heavy
— Elon Musk (@elonmusk) June 25, 2021
Musk responded to the question with a casual "Starship Super Heavy". Musk's other big company SpaceX is planning to send a huge transportation system into deep space which is called Starship. The other half of Starship is the massive rocket booster that will help launch it into orbit called Super Heavy.
The next test flight of the Space transportation system that is built to carry payloads and humans into space will take place in a few weeks. Recently, SpaceX President Gwyne Shotwell said the company is "shooting for July" when asked about a possible launch date.
Shotwell also added that the engineers were on "the cusp of flying that system" but cautiously said that they knew it was difficult and he was hoping that they "make it".
This will be the maiden test for the Starship Super Heavy if it ends up happening in July. The spaceship is built to accommodate 100 crew members and cargo. The booster will be powered by 31 Raptor engines and Starship will have the benefit of 6 Raptor engines for travel and upright landings.
