According to foreign media reports, NASA announced a new contract under the tipping point contract award on October 14 local time. It is reported that the focus of these awards is to promote the development of commercial space technology. At the same time, NASA is preparing for its Artemis Project, which aims to achieve permanent residence on the surface of the moon for the first time in human history. Meanwhile, it will use the surface of the moon for scientific experiments and eventually move to Mars. < / P > < p > among these awards, SpaceX’s “starship” launch vehicle platform also won an award to demonstrate a key air refueling technology, the core of the platform’s operation. < / P > < p > currently, the starship is being developed at the SpaceX plant in boccachka, Texas, which will replace the company’s existing launch vehicle. At present, SpaceX mainly relies on Falcon 9 block 5 to deliver payloads to the international space station (ISS), low earth orbit (LEO) and other destinations. The Rockets use the company’s Merlin 1D engine, which produces about 845 kN of thrust and a power cycle of a gas generator. < / P > < p > Falcon 9 will be replaced by a starship with a completely different propulsion system. The system will use SpaceX’s new Raptor rocket engine, which is expected to produce a thrust of about 2200 kn and a more efficient staged combustion power cycle than Merlin. < / P > < p > more importantly, SpaceX also plans to refuel the spacecraft with a customized and improved model after take-off. This will enable the launch system to undertake deep space and lunar missions, as it will replace the fuel required for the rocket to leave earth orbit — the fuel that makes up the main weight of the rocket. < / P > < p > this refueling system attracted NASA’s attention because the agency chose to include SpaceX in its tipping point program. Specifically, SpaceX has signed a $53.2 million contract with NASA to transfer cryogenic propellant between the spacecraft’s fuel tanks. < / P > < p > SpaceX uses supercooled liquid oxygen as fuel for its Merlin engine on Falcon 9, and the company will continue to use this fuel on starships. In addition, most of NASA’s $370 million tipping point bonus is related to fuel management. < / P > < p > in addition to SpaceX, the joint launch Alliance (ULA) won a $86.2 million contract to test fuel transfer from fuel tank to fuel tank, and Lockheed Martin won a $98.7 million contract to demonstrate a space demonstration mission using liquid hydrogen to test fuel management technology.
