在spaceX的測試廠房被搞壞了。
黑傑克計劃或21點計劃是要在低軌商業衛星上搭載低成本的探測載荷，形成星間組網探測能力和任務自動規劃、自主管理能力，面向低軌預警、目標探測、高超目標對抗等應用領域。
這次搞壞的兩顆是風險降低（試驗驗證）衛星，用來測試雷射星間鏈路和任務自主管控（好像叫什麼坑老闆技術，什麼boss來著，我之前寫過）技術的。
DARPA satellites damaged at processing facility ahead of SpaceX launch

The satellites are part of the Blackjack program, an effort led by DARPA and the Air Force Research Laboratory to deploy a constellation of small satellites in low-Earth orbit.
WASHINGTON — Two satellites from the Defense Advanced Research Projects Agency that were part of an upcoming SpaceX rideshare mission have been damaged at the payload processing facility, the agency confirmed Jan. 6.
The mishap happened on Jan. 4 at SpaceX’s launch processing facility at Cape Canaveral, Florida. DARPA’s satellites were scheduled to fly to orbit on a Falcon 9 rocket as part of the Transporter-1 mission, SpaceX’s first dedicated rideshare mission scheduled to launch Jan. 14.
The Transporter-1 rideshare flight will take dozens of small satellites to a sun-synchronous orbit for commercial and government customers.
The satellites are part of the Blackjack program, an effort led by DARPA and the Air Force Research Laboratory to deploy a constellation of small satellites in low-Earth orbit.
DARPA Program Manager Stephen Forbes said Jan. 6 in a statement to SpaceNews that the satellites sustained damaged and the agency is evaluating the next steps.
「DARPA and its government partners are currently working with launch provider SpaceX to execute their root cause, corrective action process and assess damage to the satellites,」 Forbes said.
The two satellites are experiments known as Mandrake 1 and Mandrake 2 which DARPA describes as 「risk reduction」 flights to prove advanced technologies such as satellite constellation autonomy and optical inter-satellite links in advance of the actual deployment of Blackjack satellites.
According to an industry source the mishap happened while the satellites were being stacked and the payload separation system was accidentally released. SpaceX did not respond to questions on what caused the mishap.
