spacex's dragon spacecraft was successfully launched again, and the two astronauts trapped on the international space station were able to return home.
at 1:17 pm eastern time on saturday, the crew-9 mission (the ninth time to transport rotating astronauts to the international space station) in cooperation with the national aeronautics and space administration (nasa) and spacex was successfully launched. american astronaut nick hague and russian astronaut alexander gorbunov will be sent to the international space station on the crew dragon spacecraft. two astronauts, butch wilmore, are unable to return to earth due to a boeing starliner spacecraft failure. er and suni williams will also return to earth on the spacecraft in february next year.

transporting rotating astronauts to the international space station
at 1:17 pm eastern time on saturday, the spacex crew dragon spacecraft aboard american astronaut nick hague and russian cosmonaut alexander gorbunov successfully launched from cape canaveral, florida, usa. the crew dragon spacecraft will be sent to the international space station.

according to spacex’s official website, the dragon spacecraft supporting this mission has previously performed crew-4, ax-2 and ax-3 missions to and from the international space station. during the next six months of their mission, the two astronauts will conduct more than 200 scientific experiments and technology demonstrations to prepare for human exploration of areas beyond low-earth orbit and benefit humans on earth.
musk said before the launch: "the spacex dragon spacecraft will send nasa astronauts to the international space station!"
it is worth mentioning that nasa selected boeing and spacex to develop spacecraft in 2014 to transport astronauts to the international space station. under fixed-price contracts (one-time payments), nasa paid boeing up to $4.2 billion to develop the spacecraft and spacex $2.6 billion. however, spacex successfully sent the first batch of astronauts into space as early as 4 years ago. it has carried out a total of 9 missions to transport astronauts to and from the international space station, and has also won more contracts. boeing, which has a larger budget, did not carry out its first manned mission until june this year, and it needs spacex to help them clean up the "mess".
2 astronauts trapped
return to earth in february next year
after months of safety turmoil and numerous challenges, boeing's new-generation astronaut capsule, starliner, set off from the international space station on september 6 without a crew and embarked on its return to earth. return. this unusual journey marked another attempt by boeing in the field of commercial manned spaceflight, although it failed to carry astronauts home as planned. "she's on her way home." astronaut suni williams sent these mixed feelings back to the ground via radio at the moment starliner left.
according to previous reports, butch wilmore and suni williams have been at the international space station this year since arriving on starliner on june 6. during the docking process, the spacecraft suffered multiple helium leaks and thruster failures — the tiny engines the spacecraft uses to maneuver in space. after months of analysis and testing, nasa decided it was too risky to return them to earth on starliner.
sunie williams said earlier this month: "we miss our families all the time. i miss my two dogs; i miss my friends. there are so many people on the planet sending us messages, and every being together in person will make you feel at home." it is understood that their original mission was expected to last 8 to 10 days, but now they have been waiting on the international space station for more than three months.
with the successful launch of spacex, the two astronauts trapped on the international space station finally waited for the spacecraft to take them home. it is understood that spacex's crew-9 mission was originally planned to carry a crew of four, but due to a technical failure of boeing's starliner, nasa withdrew two crew members to make room for the two astronauts previously trapped on the international space station. . astronauts zena cadman and stephanie wilson abandoned the mission so that their colleagues could return to earth.
"we'll make it up and schedule them for the next mission opportunity," ken bowersox, nasa's associate administrator for space operations, said of zena cadman and stephanie wilson at a news conference the day before launch. shi said. "we really understand how hard it is to abandon a mission and wait a little longer."
it is reported that the manned dragon spacecraft will dock with the international space station around 5:30 pm eastern time on sunday. according to the plan, the two astronauts on this mission and the two astronauts stranded on the international space station will return to earth in february next year.
