Haven Demo: The Road to Haven-1

Vast is the only operational commercial space station company to have flown and operated its own spacecraft in orbit, validating key technologies for the world's first commercial station. https://t.co/E0Ye5aVw0D

Thank you Prime Minister @primeministerGR for choosing @astrovenator to become the first Greek astronaut. Adrianos will join @thom_astro and @astro_ales for @NASA’s 6th private astronaut mission to the @Space_Station in partnership with @ESA, @CNES, and the Hellenic Space Center. https://t.co/S98pVg8d6X

French President @emmanuelmacron and Greek Prime Minister @kmitsotakis announced @astrovenator will join Vast-PAM-1 astronauts @Thom_astro and @astro_ales. The mission is scheduled for 2027 to the @Space_Station in partnership with @NASA. https://t.co/JbEi0smOXS

[NASA Administrator Jared Isaacman @NASAAdmin]

Congratulations to Greece on its upcoming private astronaut mission and first trip to the @Space_Station.

As an Artemis Accords partner, Greece is already helping shape the future of exploration. With this mission, it is contributing to the creation of a sustainable LEO economy.

Un nouveau membre d’équipage rejoint la mission que je vais commander vers l’ISS en juillet 2027, Adrianós Golémis 🇬🇷. Nous sommes maintenant 3 européens 🇪🇺avec Aleš Svoboda 🇨🇿… Il nous reste une place : des volontaires ?

ESA will implement an astronaut mission to the International @Space_Station for Greece with @vast 🇬🇷👨‍🚀

@esa project astronaut Adrianos Golemis is planned to serve as mission specialist and, pending approval, become the first Greek astronaut in space. He would join ESA astronaut @Thom_astro as commander and ESA project astronaut @astro_ales as pilot on a mission planned for 2027.

At the International Space Summit in Paris, French President @EmmanuelMacron and Hellenic Republic Prime Minister @kmitsotakis announced @Astrovenator as our third member of the private astronaut mission to the International Space Station. They were joined by fellow crew members @Thom_astro and @astro_ales as well as Ambassador of the Czech Republic to France and Monaco Jaroslav Kurfürst, President of @CNES François Jacq, and our CEO @maxhaot. https://t.co/S98pVg8d6X

[Vast @vast]

Vast and @esa, on behalf of Greece, have signed an agreement for Vast’s private astronaut mission to the International Space Station in partnership with @NASA. @astrovenator is slated to serve as a mission specialist, becoming the first Greek astronaut. https://t.co/JbEi0smOXS

We design and manufacture laser retroreflector arrays in-house for Haven-1. Each array has three corner-cube retroreflectors mounted to an aluminum hub that reflect light back to visiting spacecraft, providing range and orientation during rendezvous and docking.

[Vast @vast]

An intricate tubing system, consisting of more than 300 assemblies, will move oxygen, water, coolant, and propellant throughout Haven-1. Each one is designed, bent, welded, inspected, and tested, then installed on the flight vehicle at our Long Beach headquarters.

[Vast @vast]

We design, build, and qualify Haven-1's cold plates in-house. Waste heat conducts from avionics devices into the plate, transfers to a pumped fluid loop, and the external radiator rejects it to space. These same thermal control systems will be scaled to Vast Satellite and future stations.

[Vast @vast]

Our space stations and satellites use fluid systems to transport oxygen, water, coolant, and fuel. We manufacture, test, and integrate these systems in-house with the speed, precision, and scale required to build next-generation space infrastructure, starting with Haven-1.

[Vast @vast]

We’re building safe, human-centered space stations with the support of our astronaut advisors @astro_feustel, @astro_megan, and @astro_suni. Insight from experienced crew is essential to our vision of a sustainable and continuous human presence in space. https://t.co/eDLtkvNEdg

Our wet trash system is one of several life-support systems aboard Haven-1. The system manages wet waste containment with integrated odor control and vacuum venting. It’s part of a comprehensive support system designed to keep crews safe in space.

Happy National Intern Day to the 2026 Vast class.

Over 60 students from all over the U.S. are working on the future of human spaceflight, contributing to engineering, software, manufacturing, and more. Summer 2027 applications open in September: https://t.co/VfGmr2AgxY

Vast was featured on @FoxNews’ primetime show @myviewfnc. CEO @MaxHaot and Founder @jedmccaleb hosted @laraleatrump at our Long Beach HQ, sharing a look at how we’re building Haven-1, scheduled to be the world’s first commercial space station and America’s next space station.

[Vast @vast]

We design and build Haven-1's critical power system in house, lowering cost and lead times. Here, a string of our fault-tolerant 15 kW power system is configured for hardware-in-the-loop (HITL) testing, enabling end-to-end validation using flight-identical hardware.

Our food packaging, specialized utensils, and deployable table were designed with input from our Astronaut advisors, @astro_feustel and @astro_suni. The table can be easily disassembled and stowed away, while the packaging and utensils are made for practical use in microgravity.
