Jim Brittenstein (Jim Bridenstine), director of NASA, said in an interview on Monday that he was sceptical about the timing. Due to delays in the delivery of the Commercial Crew project, NASA may have to buy more spaceship tickets from Russia to ensure that American astronauts can travel to the space station. Commercial Crew program, including Crew Dragon and Boeing's capsule, which has also been delayed for several years.
NASA hopes that the private sector will develop spacecraft to replace the Space Shuttle project, which ended in 2011.
In 2014, SpaceX received a $2.6 billion contract, while Boeing received a $4.2 billion contract. NASA originally predicted that the two companies' spaceships would be completed by 2017.
SpaceX's Crew Dragon manned spacecraft successfully completed its test flight in March this year. The company had planned to carry astronauts in July, but an accident occurred in a manned module ground test earlier this year.
Musk said 95 percent of SpaceX's resources have been invested in the development of the Dragon spacecraft and Falcon rockets. The, Crew Dragon manned spacecraft will travel to the Florida launch site for its first manned test flight in November.
"If there is any way to speed up the preparatory process, I will do my best." Musk said of Crew Dragon's progress.
Last week, Brittenstein spoke to Musk on Twitter, expecting the latter to speed up the manned spacecraft project. "I look forward to SpaceX's statement tomorrow. At the same time, commercial manned spaceships are several years late. NASA wants Musk to follow the progress of the project as much as it does with American taxpayer investments. It's time to deliver. "
In an interview with CNN, Musk responded: "Is he talking about Commercial Crew or Space Launch System (SLS)?" The latter is a deep space exploration rocket that Boeing is developing for NASA.
The project was also delayed for many years and overspent by hundreds of millions of dollars.
Briddens said he was aware that many NASA contractors had failed to deliver on time, and he hoped to hold them accountable for delays in delivery.
Brendence questioned the timing of Crew Dragon's progress because the updated emergency abort system had not yet been tested. Musk said the new system would be finally tested in October.
Briddens says Boeing faces similar challenges and hopes to complete its first test flight in a few months.
