SpaceX发射的太空军全球定位系统卫星可能会打破记录

周二,SpaceX将尝试自5月30日NASA历史性地将宇航员送入国际空间站以来的第三次发射,同时还将首次发射猎鹰9号。


计划用猎鹰9号火箭将一颗新的美国太空部队GPS卫星送入轨道,这将是该公司在2020年的第11次发射。如果继续以每周一次的速度进行发射,埃隆•马斯克(Elon Musk)的SpaceX将很容易创造一年内发射次数最多的公司纪录。


这也是SpaceX在发射一颗军用卫星后首次尝试着陆并回收其猎鹰9号火箭。据SpaceNews报道,该公司在2018年发射 了另一颗军用GPS卫星,当时美国空军认为SpaceX无法执行所需的飞行轨道,也无法让第一级助推器着陆。


此后,该公司与美国军方就修改其GPS任务要求和发射成本进行了谈判,以允许SpaceX在周二发射卫星后尝试第一级着陆。


美国佛罗里达州卡纳维拉尔角空军基地的发射窗口为下午12:55(太平洋时间3:55)。一旦直播开始,我们将把它嵌入到这篇文章中,这样你就可以回来观看直播。直播在节目播出前15分钟开始。


SpaceX还计划在上周执行其第二次Starlink拼车任务,但发射最终被推迟,新的发射日期尚未宣布。


“团队需要额外的时间来进行发射前检查,但猎鹰9号和卫星都很健康,”SpaceX在周五发射前几个小时发推文说。


这将是佛罗里达州肯尼迪航天中心一系列星链任务中的第三次。


最新的一系列任务始于5月30日历史性的成功将NASA宇航员送入轨道,紧接着是6月的两次发射。


2018年是SpaceX迄今为止最活跃的一年,发射 了21次。现在,该公司有望在2020年打破这一记录,如果所有计划都得以实现,该公司全年可能发射38次。根据今年早些时候提交给美国联邦航空管理局(Federal Aviation Administration)的一份文件草案,该公司希望继续在日程表上增加发射次数,目标是在2023年完成70次飞行任务。


许多发射将是Starlink任务,因为SpaceX希望在未来十年将其数万颗小型卫星送入轨道。该公司已经开始进行拼车,为一些商业有效载荷和一批星链“小鸟”腾出空间。


下一次星链发射将是第二次星链共享,这次是由提供高清卫星图像的“黑色天空”公司发射的两颗地球观测微型卫星。


这将是仅在6月份就发射的第三次星链,使这个不断增长的星座的规模达到近600颗卫星,更接近马斯克所说的800个飞行路由器的门槛,这将允许一些有限的宽带服务开始。

On Tuesday, SpaceX will attempt its third launch since its historic flight of NASA astronauts to the International Space Station May 30, while also aiming for a Falcon 9 first.

The planned mission to lift a new US Space Force GPS satellite to orbit atop a Falcon 9 rocket will be the company's 11th launch of 2020. Continuing this near weekly pace of launches would allow Elon Musk's commercial space startup to pretty easily set a company record for most launches in a year.

It will also be the first time SpaceX attempts to land and recover its Falcon 9 rocket following the launch of a military satellite. The company launched another military GPS satellite in 2018, and at the time the US Air Force determined SpaceX would not be able to perform the needed flight trajectory and also land the first-stage booster, according to SpaceNews.

Since then, the company and the US military have negotiated changes in its GPS mission requirements and the cost of launch to allow for SpaceX to attempt landing its first stage after lofting the satellite on Tuesday.

The launch window from Cape Canaveral Air Force Station in Florida opens at 12:55 p.m. PT (3:55 Florida time). Once the livestream becomes available, we will embed it in this post so you can come back and watch the feed, which starts about 15 minutes before launch.

SpaceX had also scheduled its second Starlink ride-share mission for last week, but the launch was ultimately postponed, and a new date for that blast-off has yet to be announced.

"Team needed additional time for prelaunch checkouts, but Falcon 9 and the satellites are healthy," SpaceX tweeted a couple of hours before the scheduled launch time Friday.

Already postponed from Tuesday and Thursday, it will be the third in a series of Starlink missions from the Kennedy Space Center in Florida.

The latest string of missions started with its historic success sending NASA astronauts to orbit on May 30, followed by two Starlink launches in June.

SpaceX had its most active year so far in 2018 with 21 launches and is now on pace to eclipse that mark in 2020, perhaps hitting 38 launches for the year total if all its plans pan out. The company hopes to continue packing its calendar with more lift-offs, aiming for 70 missions in 2023, according to a draft filing with the Federal Aviation Administration from earlier this year.

Many of the launches will be Starlink missions, as SpaceX looks to put tens of thousands of its small satellites in orbit this decade. The company has begun conducting ride-share launches, making room for a few commercial payloads alongside a batch of Starlink birds.

The next Starlink launch is set to be the second Starlink ride share, this time with two Earth-observing microsatellites for Black Sky, a company that provides high-def satellite imagery.

This would have been the third Starlink launch in June alone, bringing the size of the growing constellation to nearly 600 satellites and closer to the threshold of 800 flying routers that Musk has said would allow for some limited broadband service to begin.
