Four-man Space X Crew Dragon spacecraft wraps up six-month stay in orbit_我的网站

一 |     Two NASA astronauts, a Russian cosmonaut and a United Arab Emirates astronaut undocked from the International Space Station Sunday and headed for an overnight splashdown off Florida's East Coast early Monday to wrap up a six-month stay in orbit.Strapped into their SpaceX Crew Dragon "Endeavour" spacecraft, Crew-6 commander Stephen Bowen, pilot Woody Hoburg, cosmonaut Andrey Fedyaev and UAE crewmate Sultan Alneyadi undocked from the station's forward Harmony module at 7:05 a.m. ET to kick off a 17-hour flight back to Earth.

             

"Before we get busy, we just want to say wow!" mission control radioed a few minutes before undocking. "Can you believe it's already time to leave? We can't. ... You've done an incredible job, and to say it's been a pleasure to support you guys in this mission would be an understatement."      "Thank you very much," Bowen replied. "It's been a real pleasure and an honor to be here for this expedition. We're coming up on 23 years of continuous occupation of the International Space Station, which is absolutely amazing. Just a real privilege to be a part of it."If all goes well, the Crew Dragon will execute a 16-minute de-orbit thruster firing starting at 11:24 p.m. ET. The "burn" will slow the spacecraft by 252 mph, just enough to drop it back into the lower atmosphere on a southwest-to-northeast trajectory.                 Splashdown in the Atlantic Ocean east of Jacksonville, Florida, is expected at 12:17 a.m. ET Monday."We're definitely looking forward to our return, and for me as a rookie flyer, the final part of that unique life experience (of) decelerating from 17,500 miles an hour down to hopefully a great splashdown," Hoburg said last week.A SpaceX team will be standing by to pull the spacecraft aboard a company recovery ship and assist the crew members getting out of the cabin as they begin readjusting to the unfamiliar tug of gravity after a half year in weightlessness.Before departing the space station, Bowen, a former submariner, said he most looked forward to "the nice ocean air and peaceful calm seas. That'll be really nice to get back to."                      Hoburg said he was looking forward to a "real shower." Alneyadi said he couldn't wait to rejoin friends and family, along with enjoying "a real hot cup of coffee." As for Fedyaev, "I think my dream is a bed for good sleeping. I can lay on one side. Another side. My back. Sleeping!"After initial medical checks aboard the recovery ship, all four fliers will be flown to shore by helicopter. A NASA jet then will carry them back to Houston and the Johnson Space Center for debriefing and reunions with friends and family.Left behind in orbit were three Soyuz crew members -- station commander Sergey Prokopyev, Dmitri Petelin and NASA astronaut Frank Rubio -- and four Crew Dragon fliers launched August 26 to replace Bowen and company: Crew-7 commander Jasmin Moghbeli, European Space Agency astronaut Andreas Mogensen, Japanese astronaut Satoshi Furukawa and cosmonaut Konstantin Borisov.

             

Prokopyev, Petelin and Rubio were launched to the station last September and are wrapping up a marathon 371-day mission.They originally planned to spend six months in space, but their Soyuz ferry ship was disabled by a major coolant leak last December. The Russians opted to send up a replacement spacecraft, and the crew's mission was extended an additional six months.A fresh Soyuz crew — commander Oleg Kononenko, Nikolai Chub and NASA astronaut Loral O'Hara — is scheduled for launch from the Baikonur Cosmodrome in Kazakhstan on Sept.15.Prokopyev, Petelin and Rubio will undock and return to Earth 12 days later. In so doing, Rubio will set a new U.S. record for the longest single spaceflight by an American astronaut.                      Launched atop a SpaceX Falcon 9 rocket on March 2, the Crew-6 fliers will have spent 185 days and 22 hours off planet, circling the globe 2,976 times while traveling 78.9 million miles through space. At splashdown, Bowen, the only space veteran on the crew, will have logged 227 days in space across four missions.Over the course of their mission, the Crew-6 astronauts welcomed seven visiting vehicles, including two unpiloted Cargo Dragon spacecraft, two Russian Progress supply ships, a Northrop Grumman Cygnus cargo carrier and two piloted Crew Dragons.They also carried out three spacewalks. Bowen and Hoburg ventured outside twice to install new roll-out solar blankets and Alneyadi joined Bowen for a third excursion to retrieve a failed antenna package and to carry out other maintenance."It's certainly been the experience of a lifetime, and a real honor to get to spend six months, six incredibly short-feeling months, living and working aboard this incredible orbiting outpost," Hoburg said before departing the station. "I think we got a lot done."

。    BEIRUT -- Iran’s foreign minister on Saturday called on Israel to stop its attacks on Gaza, warning that the war might expand to other parts of the Middle East if Hezbollah joins the battle, and that would make Israel suffer “a huge earthquake.”Hossein Amirabdollahian told reporters in Beirut that Lebanon’s Hezbollah group has taken all the scenarios of a war into consideration and Israel should stop its attacks on Gaza as soon as possible.Israel considers Hezbollah its most serious immediate threat, estimating it has some 150,000 rockets and missiles, including precision-guided missiles that can hit anywhere in Israel. The group, which has thousands of battle-hardened fighters who participated in Syria’s 12-year conflict, also has different types of military drones.Hezbollah fighters have been on full alert along Lebanon’s borders with Israel following last Saturday’s attack by the militant Palestinian group Hamas that left hundreds of Israeli civilians and soldiers dead.On Saturday, the Israeli military said an Israeli drone strike along the border with Lebanon killed a “cell” that was trying to infiltrate into Israel. On Friday, Hezbollah said its fighters fired several rockets at four Israel positions along the border. On Saturday afternoon, Hezbollah fighters fired a barrage of rockets and shells at Israeli positions in the disputed Chebaa Farms. Israeli troops fired back on nearby areas in southern Lebanon. Amirabdollahian discussed during a meeting in Beirut Saturday the situation in Gaza and the region with the top Hamas official in exile, Saleh Arouri, and the leader of the Palestinian Islamic Jihad group, Ziad Nakhaleh, according to Hezbollah's Al-Manar TV.Hamas officials have repeatedly said that last Saturday’s attack on southern Israel that killed over 1,300 civilians and troops was the work of the Palestinian group and Iran had nothing to do with it. Hamas officials did not respond to calls by The Associated Press to confirm and give details about the meeting. Amirabdollahian left Beirut Saturday afternoon following a tour that took him to Iraq, Syria and Lebanon, where Tehran enjoys wide influence.Amirabdollahian said he met Friday Hezbollah leader Sayyed Hassan Nasrallah, who briefed him on the group’s conditions in Lebanon.“I know about the scenarios that Hezbollah has put in place,” Amirabdollahian said. “Any step the resistance (Hezbollah) will take will cause a huge earthquake in the Zionist entity.”Amirabdollahian added: “I want to warn the war criminals and those who support this entity before it's too late to stop the crimes against civilians in Gaza, because it might be too late in few hours.”With an eye toward Hezbollah, U.S. President Joe Biden has warned other players in the Middle East not to join the conflict and has sent American warships to the region and vowed full support for Israel.The Iranian foreign minister said he will be contacting U.N. officials in the Middle East because “there is still an opportunity to work on an initiative (to end the war) but it might be too late tomorrow.”The possibility of a new front in Lebanon brings back bitter memories of a vicious monthlong war between Hezbollah and Israel in 2006 that ended in a stalemate and a tense detente between the two sides.。
