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

A |     8月26日讯 《体坛周报》记者马德兴撰文谈到青训话题，文章表示，真正的青训需要很多年，而互联网最擅长制造的却是“一个下午的天才”。在采访过程中，清华附中马约翰体育特长班的办公室主任及竞赛主管陈广虽然没有多言，但提到了一点担忧，就是现在的年轻球员过早地进入到了公共舆论场。

B |     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."

。或许是碍于目前的身份，陈广并没有就此话题展开。但是，他所提及的这一点却让记者深有同感。同样是采访青少年足球，十多年前与80后、85后、90后等青少年球员接触，与如今接触05后、06后甚至更小的青少年球员，记者的感受完全不同。如今的青少年球员所关注的、在意的东西与10多年前的小球员的关注点相比，已经发生了巨大甚至可以说是根本性的变化。现实社会中，短视频、社交媒体、比赛集锦、自媒体账号等等，可以让一个十四五岁的孩子在真正成为职业球员之前就拥有大量关注度，一段精彩的过人短视频可能会收获十几万的点赞；一场比赛可能制造一个“天才少年”；一支少年队也可能通过精心包装，变成一个具有巨大流量的IP。但是，这种变化某种程度上正在侵蚀着青少年球员培养过程中最需要的东西——专注。过去，教练、老师或家长会告诉孩子：“低头做人，脚踏实地做事。”现在却很难要求一个孩子“两耳不闻窗外事”。记者曾亲历过这样的事情，而且不止一两次。在某国少队的训练场边，记者亲耳听到小球员小声告诉身边的队友：“马记者来看咱们训练了，在拍东西呢，赶紧好好表现。”乍一听，好像这没有什么，一切都很正常，而且球员们训练状态显得很兴奋、很不错。但实际上，球员们真正在意的并不是训练本身，而是关注自己的视频、形象；关心自己是否能出现在记者的镜头之中；关注别人怎么评论；关注曝光度等等。他们的视线早就不在每天最枯燥的技术改进上。这其实就是全新时代下，青训工作中所需要面对的一个全新课题，即如何让球员们更专注。所以，当陈广主任提及自己的担心时，记者才感同身受。可以这么说，清华附中今天最需要的，并不是更多的“神话”。当校园球队已能够培养国字号球员时，最危险的反而可能是把“人才培养”重新变成“流量生产”，真正的青训需要很多年；而互联网最擅长制造的却是“一个下午的天才”。这也是记者在采访完陈广后深感另一个很值得关注与思考的东西。
