The payload roundup for Transporter missions is always interesting and is a good quick health check on the small sat industry.

  • Planet, Spire, Iceye constellation deployments
  • 2x D-Orbit tugs, Impulse’s 3rd Mira tug, Varda’s 5th capsule
  • a ton of stuff I haven’t heard of, including 8x IRIDE imaging sats

Blue Skies Space’s Mauve commercial UV telescope that sells tasking time is interesting.

ESA’s HydroGNSS mission to measure GPS signals off water and weather is cool.
