更重要的一点是，Mars 2020还着眼于将来。它计划展开一场超时空接力赛：采集火星岩石和土壤样品，存储起...
For more than a year, scientists and aerospace engineers have been awaiting NASA’s decision on how to rescue the troubled Mars Sample Return mission, which aspires to bring Martian rocks and soil to Earth but was halted amid dismay over the project’s cost and glacial timeline....
NASA to Send Sample-Return Mission to Earth-Bound Asteroid [Video]Robin Lloyd
An independent review board concluded last year that NASA’s Mars sample return mission could cost as much as US$11 billion, more than the cost of launching the James Webb Space Telescope. In a report released today, a separate NASA review team concluded that even if the agency spent that ...
NASA原计划通过多阶段任务实现样本返回:一辆“火星升空航天器”(Mars Ascent Vehicle, MAV)将样本从火星表面发射到轨道,再由环绕火星的“地球返回轨道器”(Earth Return Orbiter, ERO)接手,最终带回地球。听起来天衣无缝,但2024年的一次审查却让NASA傻了眼——整个计划的成本高达110亿美元,成功率却低于预期,最糟的...
NASA has released a cinematic animation showing some of the key moments from the upcoming Mars Sample Return (MSR) mission. Mars Sample Return: Bringing Mars Rock Samples Back to Earth The complex uncrewed mission involves multiple spacecraft and is set to launch in 2033. ...
NASA established the independent review board in May 2023 to closely examine the Mars Sample Return program. The board estimated the total cost of the mission to be between $8 billion and $11 billion. The Martian samples would like...
In short, the approach taken jointly by NASA and ESA with MSR has been focused on returning the best possible samples, Hamilton said, "and that could end up meaning that MSR is not the first Mars sample return mission." China scoops ...
NASA is prepping for an ambitious extraterrestrial mission. In concert with the European Space Agency, NASA plans to launch rock samples from Mars (currently being collected by the Perseverance rover) and send them to Earth, an endeavor aptly named the "Mars Sample Return Campaign." The U.S....
A "selfie" shot by NASA's Perseverance Mars rover, which has been exploring Jezero crater and collecting rock and soil samples from an ancient lakebed and river channel for eventual return to Earth by a Mars Sample Return Mission. NASA is currently studying two options to lower the cost an...
