“猎鹰”-9火箭将ORBCOMM公司卫星送入错误轨道

这错误……

这好比是搭便车结果半道被甩下来，人家自己到目的地了

基本就废了吧？…

也不一定，本来就是带有试验性质的卫星，现在定性这次发射是“部分失败”，如果通过星上发动机变轨成功，那么可以定性为“部分成功”

发动机死火使得推力不足 分离时轨道太低 卫星自己的燃料也不足以使其变轨到预定轨道。。。

也就是说过几个月就坠入大气层烧毁？

SpaceX这次的危机公关一味隐瞒，透明度太差了。

什么情况？

甩货太随意了？

三峡大坝引起的蝴蝶效应

就算成功升上正常轨道
之后修正姿态及轨道的燃料亦耗尽
变成太空垃圾
有机会撞太空站

主要对接任务能完成吗？

没有通过星上发动机变轨成功的可能。
这颗卫星已经登记为太空垃圾，掉下来之前可以发点余热

还吹呢，少一台发动机没事！

这个东西打载人飞船，谁敢坐啊

大航海时代好像也很常见。

最新消息，这个卫星已经坠入大气层烧毁。看来报道的230x350公里轨道也是错误的。

主要任务是完成了， 次要任务遇上了ISS的禁飞区， 软件没有后著， 也有传说不够燃料了。

保险公司会赔么？或者说这货有买保险么？

再入变轨啊

难得你这么忠心耿耿，可惜不得要领。
这卫星通讯传感系统均正常，卫星的主人抓紧这四天的宝贵时间进行各种测试，试验，时间就是金钱，怎么可能当催命鬼启动让它加速坠落？？？

的确是完成测试了， 再玩下去， 保险就不赔了。

Orbcomm declared its OG2 prototype spacecraft a total loss Oct. 11 after the second-generation communications satellite that flew as a secondary payload on SpaceX's first cargo mission to the International Space Station (ISS) was dropped into a lower orbit than intended.

The New Jersey-based satellite messaging services provider said it had filed a claim against an insurance policy that covered the spacecraft for up $10 million, which Orbcomm said would largely offset the expected cost of the satellite and its launch.

“We appreciate the complexity and work that SpaceX put into this launch,” Orbcomm CEO Marc Eisenberg said in an Oct. 11 statement. “SpaceX has been a supportive partner, and we are highly confident in their team and technology.”

An anomaly that crippled one of the SpaceX Falcon 9 Merlin 1C engines during the Oct. 7 launch did nothing to disrupt the rocket's primary mission of lofting SpaceX's Dragon cargo vessel to the ISS. But Orbcomm says it was responsible for the the total loss of the OG2 satellite, which was to expected to fly before SpaceX launches the full constellation of 18 second-generation Orbcomm spacecraft on Falcon 9 vehicles over the next two years.

Orbcomm Oct. 11 that telemetry and command capability had been established with OG2 and several critical system verifications were performed before it reentered the atmosphere Oct. 10. The solar array and communications payload antenna deployed and engineers verified the performance of various components of both the OG2 satellite bus and the communications payload.

“The OG2 satellite bus systems including power, attitude control, thermal and data handling were also tested to verify proper operation,” Orbcomm said. “The unique communications payload, which incorporates a highly reprogrammable software radio with common hardware for both gateway and subscriber messaging, also functioned as expected.”

Orbcomm says the data will allow it to focus on completing and launching the OG2 satellites as the primary mission payloads on two planned Falcon 9 launches, the first in mid-2013 and the second in 2014, directly into their operational orbit.

“Had Orbcomm been the primary payload on this mission, as planned for the upcoming launches, we believe the OG2 prototype would have reached the desired orbit,” the company said.

你抄的文章，包括加红色的一段，没有变轨加速坠落，完成测试的意思。

Orbcomm 说OG2已离轨(也就是total loss)，不过在轨时已经基本完成并通过星上各个系统的测试。Orbcomm 将向保险商追讨多达1000万美元的赔偿。

一个芯级就敢装9台发动机，活该……

请不要玩文字游戏， 文章写明“完成测试”， 的确没有写“变轨加速坠落”。

否定og2远拱点到达300km是没有意思及不智， 这就必需同时否认龙成功入轨这个现实。

两天轨道存留， 出于近拱点200km区出现大阻力， 使远拱点高度急速下降。

另一个原因是og2本身重量低及大横切面面积。 就是火箭芯级这样密度较高的物体， 最多也是多留一两天。

og2本身有轨道调姿， 若有需要可以把近拱点推高一点点， 延长留在空间的日子来完成测试， 很明显没有这个必要。

og2最后有没有使用再入变轨， 那就不得而知。
