Microsat-R was intercepted at an altitude of ~300 kilometers, and there is still debris reaching 1,400 kilometers higher (and 8 other pieces 700 kilometers higher). Those pieces regularly pass through the orbital regimes of the ISS, low-orbiting weather satellites, nearly all satellites in sun-synchronous orbits, and a ton of LEO communications satellites.

Doug Messier has a hell of a read over on Parabolic Arc about the Firefly saga over the last three years. We’ve heard bits and pieces of this before, but there’s a ton in here about investors, some Vulcan (Stratolaunch) involvement I had not heard previously, and a bunch of accusations in both directions.

It’s been a hell of a last day or two for NASA and Boeing. I wanted to share a handful of thoughts I’ve had since launch.

All week, I’ve been appearing on the AGI YouTube channel alongside T.S. Kelso of CelesTrak. As we head into the weekend and a long holiday, find some time to settle in and learn about CelesTrak.

Jake and Anthony are joined by Marina Koren of The Atlantic to discuss the very Off-Nominal-esque Apollo 12 mission, regional Pennsylvania sayings, and to deliberate on and announce the 2019 Off-Nominal Award winner!

This is definitely an improvement over the status quo, which is that you can launch a single satellite and that covers your spectrum rights for thousands more that you may never launch.

When I was at IAC, I heard that this would be flying on the back of Centaur. That made sense, as ULA was a partner in Nanoracks’ Outpost program. But after this announcement, I went looking, and ULA hasn’t appeared in anything related to Outposts in months.

Last week, NASA announced the addition of SpaceX, Blue Origin, Sierra Nevada, Tyvak, and Ceres Robotics to the list of Commercial Lunar Payload Services providers. That brings the total number of providers to 14.
