Our vehicle Mira has successfully deployed our payload! Thank you @TrustPointGPS for flying on LEO Express-1 💫Mira still has secondary missions to complete— stay tuned for more!#MiraFirstFlight #ImpulseSpace
A wonderful hour long interview/chat with Tom Mueller with some great info about the company and how things are going with the first vehicle in orbit.edit/gongora: tweaked URL
Proud to have joined Jake and Anthony on the Off-Nominal Podcast!We got into my work in space propulsion, my time at SpaceX, and how I have learned to embrace trying new things; you have to be optimistic when faced with new challenges.When we recorded the podcast, Impulse had just launched our new craft, Mira. Since then, we made successful contact and can communicate with the craft!Give the podcast a listen and let me know what you think!offnom.com/episodes/132
🔥 LEO Express-1 mission update: Mira has #Impulse! Yesterday marked a major milestone as we executed a flawless first-time firing of all eight 5lb (22N) Saiph thrusters on our orbital transfer vehicle, Mira. Hats off to our team for their engineering preparation and a well-tested system.
Here's a snapshot of LEO Express-1 achievements so far:🕔 From a blank-sheet design to an operational spacecraft in-space in under 15 months⭐️ Our in-house developed thrusters, valves, ignitors, pressure transducers, star trackers, cameras, core avionics, and lightweight composite overwrapped pressure vessel (COPV) tanks all hit TRL 9🌈 Ground-up builds of new flight software (FSW) and guidance, navigation, and control (GNC) capabilities.🌱 Rapid propellant loading using green propellants from a domestic supply chain☀️ Autonomous sun pointing and system checkouts post-deployment⚡️Power positive operations✚ Attitude control through 16x reaction control thrusters🛰️ Successful deployment of a customer's 3U CubeSat🔥 First-try ignition of all eight bi-propellant Saiph thrusters👨🚀 All operated from our sparkly-new Mission Control center
Introducing #Helios, our new high-performance kick stage. Helios is designed to transfer 5+ tons from LEO to GEO in under 24 hours, dramatically cutting customer launch costs and time to operations.Check the design specs 👉 impulsespace.com/updates/impuls…
The fuel choice is partly a nod to the reusable future of spaceflight that Impulse Space hopes to tap into. "SpaceX needs 1,000 [metric] tons to refuel Starship," he said. "Just give us a sip. We'll take our 14 tons, and we'll be glad to pay for it. And we can continue to reuse these."

If the kickstage is hidden inside the faring and somewhat tucked into the interstage, why bother constructing it with a skin, could they save some weight without it? Would look ugly but it works for the Soyuz-2 Fregat.
It will be interesting to see if SpaceX itself introduces something like this. They may have their own methane thrusters ready to go as part of the HLS landing method.I would have thought a smaller thruster would be preferable to a single thruster. You could gang them together for engine-out capability.

What is "F9-5500", why the 5500 after Falcon 9?
Quote from: TheKutKu on 01/17/2024 07:50 pmWhat is "F9-5500", why the 5500 after Falcon 9?The only thing I can come up with is that SpaceX lists their reusable GTO capacity as 5.5t
Anyone done the math on what mission profiles you could throw with this to the outer planets on a FH yet?
