We finished ENOS! 🚨🚨 ENOS is currently on its way toward Vandenberg Space Force Base for Launch later this Fall. It will orbit for approximately 2 months, before initiating its reentry that ends with a splashdown off the coast of Florida, where the satellite will be recovered. ENOS is built for reusability, and will be the first reusable satellite ever! 🚀 Read more about it here: lnkd.in/ejvKtM4W

Thank you for covering our upcoming Launch @Genevaexpat & @BreakingDefense! breakingdefense.com/2026/07/reditu…

Thank you for covering our first Spacecraft! @demarest_colin & @axios

@anu_bonth Reditus High Enthalpy Ablative

@StefReditus What does RHEA stand for?

Got some questions about ENOS a bunch, so answering them here. ENOS is large, as in, a person could fit inside large. See a behind-the-scenes picture of it here for scale. We built ENOS in 15 months from clean sheet, with a team of 12 FTEs, lean teams go fast! Our team built our own TPS-solution in-house, it's called RHEA.

@anu_bonth @ReditusSpace A couple, the payloads are primarily on the in-space-manufacturing side

@StefReditus @ReditusSpace Flying any fun payloads?

@anu_bonth @ReditusSpace Thank you! Few things more important than iteration speed!

@Douglas__Gorman @ReditusSpace Yes it will! That's exactly right!

The reentry guy strikes again! The idea of reusing a reentry vehicle is so simple, yet it has the potential to fundamentally change the economics of Earth return. If @ReditusSpace pulls this off, it could make the future of in-space manufacturing affordable and routine.

Huge Milestone! 🚀 They grow up so fast 🥹

There's never been a better time to build a startup based in atoms not bits. Hardware here contains many sub-sectors, but robotics and defense-related hardware are the fastest growing.

Segment from SpaceX's S-1: "we believe that over time each of these markets could eventually represent multi-trillion-dollar economic opportunities. These new markets include long haul point-to-point terrestrial travel, space tourism, in-orbit manufacturing, asteroid mining, energy production and manufacturing on the Moon and Mars, and passenger and cargo transportation to the Moon and Mars"

Today is the deadline to apply for YC Summer 2026. If you're still hesitating: the companies that change the world don't wait until they're 100% ready. Applying is sometimes literally the first step.

For the first time since the 70s, people are now on the way to the Moon again! 🚀🚀

Godspeed Artemis II! 🚀 ~15 Minutes until Launch! Humans back to the moon - It has been too long.

Couldn't have said it better!

@garrytan 🚀

YC is the YC for space tech

This box will ship the first reusable satellite ever in a couple months! 🚀 🚀

rentahuman.ai Clawdbots can now commision people for physical tasks, I feel like this is getting slightly creepy.

@BrantTracVC Hahaha hell yeah @BrantTracVC ! Awesome!🚀

Do you really believe a guy with a Puffer Vest and 3 years at Bain can pick winners better than a Deep Learning Algorithm? Goodbye Puffer Vest. Hello Tiger Sweater. Welcome to Trac.Vc

1 Million Satellites! Seems like we're doing this. WILD.
