every week I become a little bit more of a "if LLMs are 10x better at writing software, where is all the 10x better / faster software" truther – at Scenic Oaks, TX

The worst unit is decibel: It isn't even a unit, isn't defined consistently across fields, hides an arbitrary reference scale and is named after Alexander Bell but spelled 'bel'

You have no idea how much it means for me to have the opportunity to save the Earth with the guy who lambasted James Cameron for using Papyrus.

Type of thing you scoff at if you’ve never operated satellites and solemnly nod at if you have
According to a NASA report Lunar Trailblazer failed because the software pointed the solar panels *away* from the Sun.
The NASA panel says Lockheed did not properly test the solar panel pointing software before launch.

🚀 LEO Express 3 is officially underway!
Mira has successfully launched aboard the Transporter-15 rideshare mission from Vandenberg Space Force Base.
Following separation from SpaceX’s Falcon 9, we’ve received initial telemetry data and confirmed two-way comms, as well as deployment of the solar arrays. The vehicle is healthy and we are moving through commissioning procedures.
Stay tuned for mission milestones as Mira’s journey unfolds: impulsespace.com/updates/leo…

Built in-house. Tested to fly.
The Mira flying on our LEO Express 3 mission is undergoing exhaustive functional testing to validate each of its subsystems ahead of launch, including:
⚙️ Vacuum
⚙️ Vibration
⚙️ Light to battery end-to-end

We need to:
1) Gather all of the people who mistakenly think space can't cool things off
2) Gather all of the people who mistakenly think space instantly freezes things solid
3) Lock them together in a TVAC chamber until they come to equilibrium

Haven Demo moves into the Thermal Vacuum chamber (TVAC), where we simulate the extreme temperatures and vacuum conditions of space. This test allows our team to replicate vehicle operations in space and gain valuable insights that will help us prepare for Haven Demo being in-orbit.

I would be totally on board with this movement being called McMaster Deco

We're pleased to announce our multi-launch agreement with @SES_Satellites, a global content and connectivity provider, to use our Helios kick stage to transport SES's satellites from Low Earth Orbit (LEO) directly to high-energy orbits in hours. (1/3)

guys I think the rockets really don't like lockheed

Two burns. One orbit apart. 🔥
Mira completed two burns just a single orbit apart — a first for the vehicle. This rapid turnaround boosts flexibility, allowing multiple orbital adjustments to fit into minutes or hours, depending on burn magnitudes.
Precision and responsiveness: that’s how we deliver mission success. 🛰️🚀
