On Thursday evening, US Eastern time, Elon Musk, CEO of SpaceX, delivered a speech at Starbase, Texas, introducing the latest progress in starship development < p > musk pointed out that the starship is designed to fly three times a day. Theoretically, the spacecraft can be launched again every six to eight hours, the booster can take off again in an hour, and it only takes six minutes to reach space and return < p > musk disclosed the technical specifications of the Starship: it can put 100 to 150 tons of payload into orbit, and may carry 200 tons of propellant into orbit to refuel other starships in space. He said it was necessary to go to Mars < p > this is also an important part of SpaceX's variant starship developed for NASA's human landing system (HLS). As part of Artemis III, the third mission of Artemis' return to the moon program, the spacecraft will return American astronauts to the lunar surface in 2025 < p > musk calls the launch tower and launch system "zero stage", which is as important as the first and second stages. He also revealed that it took SpaceX 13 months to build the launch tower at Starbase. The launch tower can not only support rocket launch, but also "catch" the Starship when it returns from orbit to help complete the recovery < p > musk also introduced the super heavy booster. From the perspective of thrust, it will be the largest launch vehicle ever to enter orbit. The thrust is more than twice that of NASA Saturn 5 rocket, which helped humans land on the moon. Musk said that the super heavy booster will be the largest of all aircraft. Of course, it must be able to fly < p > musk said: "the super heavy booster was originally 70 meters high, but then the team removed an additional part and accidentally reduced its height to 69 meters." < p > musk introduced the heat shield of the starship in detail. "It's the largest heat shield in the world," he said, noting that it was produced by a small factory in Florida called bakery. "We need a heat shield that can withstand extreme temperatures but can't be ridiculously expensive, and the team has achieved that goal," Musk said < p > at present, one factor hindering the entry of interstellar spacecraft into orbit is environmental assessment. Musk was asked when he might conduct an orbital test flight, but he seemed to deliberately avoid the essence of the problem. "We don't know much about the FAA evaluation. We only know a rough idea. It may be approved in March. That's all we know," he said Musk later added that he was confident that the Starship would enter orbit by the end of this year < p > musk said that SpaceX will use starships to carry out Star chain missions and manned space missions with NASA, but did not give a timetable for when these missions are expected to be carried out. He mentioned the dearmoon mission, which is expected to fly around the moon in 2023. However, it is unclear whether this timetable will be achieved. In less than 24 months, there seems to be a lot of work to be done < p > < p > musk reiterated his commitment to developing starships, the most important of which is to make humans a multi planetary species. "In the long run, it is very important and necessary for us to become a multi planetary species and eventually surpass the solar system," he said < p > musk also pointed out another reason, that is, in order to inspire mankind, he believes that there are too many problems to be solved on earth. "I totally agree that more than 99% of the resources should be used to solve the problems on earth. But one day, we can turn Mars into a planet like earth," Musk said < p > musk also talked about many theoretically possible things, but did not explain in detail how difficult some tasks will be to perform. He said it would take a lot of work to transform Mars. This sounds exciting and encouraging, but it will take decades At the same time, musk urged mankind to act quickly. "Frankly speaking, today's civilization feels a little fragile," he said
