First SpaceX, Now Impulse + Pathfinder #0049 with Tom Mueller

Shying away from the limelight is an art Tom Mueller has perfected. The SpaceX founding member and mastermind behind Impulse Space is not a frequent podcast flier, with only one previous episode in the wild (that we could find). However, Mueller recently agreed to jump into the hot seat on the Pathfinder pod.
Mueller is best known for his instrumental role at SpaceX as propulsion CTO, but he’s now turned his sights to his new venture, Impulse Space. Founded in 2021, Impulse aims to provide reliable and economical in-space transportation services. The company services include GEO/GTO/LEO logistics, in-orbit servicing, spacecraft life extension, active debris removal, and situational awareness.
The company plans to operate within Earth’s orbit and beyond, including lunar and Mars missions, which Mueller believes will open the gateway to space resource transportation, asteroid mining, in-space manufacturing, and propellant depots.
Tech and commercial traction: Mueller shared that their initial vehicle offerings include:
Mira, which will be used to transport payloads in LEO and perform on-orbit services
Helios, which will be a kick stage for transporting large satellites to GEO and beyond Earth’s orbit to the Moon and Mars
Last summer, the company announced a partnership with Relativity to launch the first private mission to Mars and just last week Orbit Fab announced that it would use a vehicle developed by Impulse Space for an in-orbit refueling demonstration.
A sneak peek…
In addition to Impulse’s origin story, Mo and Tom discuss:
Building propulsion systems
Initial target markets
Engineering thrusters vs engines
Mira’s first mission this October
Lessons learned (and memorable stories) from SpaceX
And much more…

Debt limit deal could keep NASA budget flat

The debt limit deal reached late Saturday night contains both good and bad news for NASA.
The plan from President Joe Biden and Speaker Kevin McCarthy (R-CA), which is expected to get a vote in the House on Wednesday, would keep non-defense spending roughly flat in fiscal year 2024, with a 1% bump in 2025, according to White House officials.
By the numbers:
$27.2B = NASA’s fiscal 2024 budget request
$25.4B = NASA’s fiscal 2023 funding
It’s important to note that the debt limit deal sets the cap on government-wide non-defense spending, not on specific agencies. So it will be up to appropriators to decide how much of the non-defense pie goes to NASA, and they could either impose more significant cuts or grant some relief. But if the proposed plan is applied evenly to the space program:
The bad news: A flat fiscal 2024 budget would be $25.4B, putting the space agency about $1.8B under its request. The agency’s budget request included plus-ups for the human landing system for Artemis moon missions, space technology, biological and physical science programs, and Earth science, according to a Planetary Society analysis.
The good news: A flat budget for 2024 would be better for the space agency than two plans proposed by the GOP that would further curtail NASA’s budget. The House passed a bill this month that would cap fiscal 2024 spending at fiscal 2022 levels. If all agencies absorbed that cut equally, that would have meant $24B for the space agency.
But Republicans were also considering a plan to make even deeper cuts to non-defense discretionary spending to protect defense spending, which would amount to a 22 percent cut to non-defense agencies. For NASA, that would mean a budget of about $19.8B.
