https://spacenews.com/spacex-l3harris-win-space-development-agency-contracts-to-build-missile-warning-satellites/This reminds me of SpaceX winning part of the DoD Space Development Agency Tracking Layer Tranche 0 LEO missile warning satellite contracts (along with L3 Harris) using the Starlink satellite bus. These aren't supposed to launch until September 2022 at the earliest (also on Falcon 9 along with LEO communication Transport Layer Tranche 0 satellites, by Lockheed Martin and York Space Systems, but to polar orbit from Vandenberg), but I can see SpaceX sending some test satellites up to orbit either at their own plans or by some unique US Government requirements earlier to mid-inclination LEO.
SpaceX Falcon 9 B1061-9 launches Globalstar FM-15 from SLC-40.Overview:https://www.nasaspaceflight.com/2022/06/spacex-globalstar-falcon-9/Livestream:youtube.com/watch?v=W40YFNse9TE…
Staging 1-2. Thunderstorms below!
Falcon 9 B1061-9 lands on SpaceX Drone Ship "Just Read the Instructions".Three Falcon 9 launches, three recoveries, in 36 hours!Now up to 126 successful Falcon booster recoveries.
SES-2 is complete and that's an interesting setup on the front end of the Second Stage.
S/C Sep for Globalstar FM-15 (the other passenger is a mystery). Three successful missions in under two days.
Falcon 9 streaks to orbit at 12:27 a.m. EDT this morning with the Globalstar FM15 satellite
Just after midnight #SpaceX launches a spare #GlobalStar satellite towards orbit from launch complex 40!📸 by me for @SpaceflightNow
Congrats to SpaceX Falcon team for executing 3 flawless launches in 2 days!
Quote from: gongora on 06/19/2022 04:45 amAnyone want to explain what this "parking orbit" has to do with launching a Globalstar sat? Looks like the mission profile could be:1. Direct injection into a 533 x 533km orbit (1:34:51 period)2. Release payload 'X'3. SES2 to raise apogee to a 533 x 1200km (ΔV about 174 m/s)4. SES3 to circularise at 1200 x 1200km (ΔV about 170 m/s)5. Release Globalstar.

There was a 4th second stage burn for disposal, since a debris zone was specified in the Pacific. This burn would be required, since a 1200 km circular orbit will take forever to decay naturally, much more than the 25 years that is the standard limit for space debris minimization
