On Friday, local time, the U.S. Government Accountability Office (GAO) rejected the protest against the blue origin of the space company owned by Amazon founder Jeff Bezos, It also said that NASA only awarded the contract of lunar manned lander to Elon Musk's space exploration technology company SpaceX, which complies with relevant regulations < p > Kenneth Patton, executive deputy general counsel of Gao, wrote in a statement: "when NASA decided to award the contract to only one company, it did not violate the procurement law or other relevant regulations. The evaluation of all three bidding proposals is reasonable and in accordance with applicable procurement laws, regulations and announcement provisions. " The protest was jointly filed by blue origin and dynetics, a U.S. defense contractor < p > GAO's ruling supports NASA's unexpected decision in April to award the contract for the lunar manned lander worth about $2.9 billion only to SpaceX. SpaceX once competed with blue origin and dynetics for the two contracts expected to be signed, but NASA finally chose SpaceX because the U.S. Congress allocated less money for the project than expected < p > NASA said that the Gao's ruling would allow the agency to "set a timetable for the first manned lunar landing in more than 50 years". "NASA will provide the latest progress of Artemis, manned landing system and human return to the moon as soon as possible," the agency said. We will continue to work with the Biden administration and Congress to ensure funding for the return of the United States to the moon through cooperation with U.S. business partners. " < p > the spokesman of blue origin said: "we still believe that NASA's decision has fundamental problems, but due to the limited jurisdiction of Gao, the agency is unable to help solve these problems. We will continue to advocate signing two direct suppliers because we believe this is the right solution. The manned landing system project now needs competition, which is the best solution for NASA and our country. " < p > GAO's ruling resolved the dispute over NASA's manned landing system project, which is one of the last key parts of NASA's plan to return American astronauts to the lunar surface. Prior to the recent contract award, NASA had awarded nearly $1 billion in concept development contracts, including $135 million for SpaceX, $253 million for dynetics and $579 million for blue origin < p > when choosing SpaceX for the next round of development, Nasa decided to provide financial support for SpaceX's starship project. The company has always tested the spacecraft prototype at its development facility in Boca Chica, Texas. NASA plans that when its capsule reaches lunar orbit, astronauts will use interstellar spacecraft to transfer from the agency's Orion spacecraft to the lunar surface < p > shortly after NASA announced the news in April, blue origin and dynetics protested to Gao respectively to challenge NASA's bidding procedures and decisions. Blue origin condemned the process as "flawed" and said NASA "moved the goal post at the last minute". The company also revealed that its bid was about twice that of SpaceX ($5.99 billion). NASA later revealed that dynetics' bid was higher, reaching $8.5 billion < p > the impact of blue origin and dynetics' protest is that NASA has been unable to promote the development of manned landing system with SpaceX, and the project is basically at a standstill until Gao makes a decision. Shortly after his first manned flight to space aboard the blue origin spacecraft, Bezos wrote in a letter to NASA earlier this week that he was willing to exempt NASA from the contract cost of up to $2 billion for the lunar manned lander < p > Bezos wrote in his letter: "we are ready to help NASA reduce technical risks, solve budget constraints and put Artemis program back on a more competitive, credible and sustainable development path. Without competition, NASA's short-term and long-term moon landing ambitions will be delayed, and will eventually pay more costs, which is not in the national interest. " Linda mills, a blue origin executive, said that Bezos "did not change the offer" after the Gao issued the ruling& nbsp; （ Small) < / P > < p >
