Haven-1 is a planned space station in low Earth orbit that is currently in development by American aerospace company Vast.{{Cite web |first1=Mike |last1=Wall |date=10 May 2023 |title=Vast Space to launch 1st private station on SpaceX rocket in 2025 |url=https://www.space.com/vast-space-private-station-spacex-launch-2025 |access-date=11 May 2023 |website=Space.com |language=en}} The station is expected to launch no earlier than May 2026 atop a SpaceX Falcon 9. The first mission to Haven-1, Vast-1, is expected to launch a crew of four astronauts on board a Crew Dragon spacecraft to the space station for thirty days.{{Cite web |last=Foust |first=Jeff |date=10 May 2023 |title=Vast announces plans for first commercial space station |url=https://spacenews.com/vast-announces-plans-for-first-commercial-space-station/ |access-date=11 May 2023 |website=SpaceNews |language=en}} More launches are expected to occur using Crew Dragon to shuttle astronauts to and from Haven-1 over the course of its lifespan.{{Cite web |url=https://bloomberg.com/press-releases/2023-05-10/vast-announces-the-haven-1-and-vast-1-missions |first=Vast |last=Space |publisher=Bloomberg |date=10 May 2023 |title=Vast Announces the Haven-1 and Vast-1 Missions |access-date=12 June 2023}}

The station will be unable to sustain itself over a long period of time and will rely on the Crew Dragon for long-term missions by using its life support systems.{{Cite web |url=https://reuters.com/technology/space/space-startup-partners-with-spacex-launch-commercial-space-station-2023-05-11 |first=Joey |last=Roulette |publisher=Reuters |date=11 May 2023 |title=Space startup partners with SpaceX to launch commercial space station |access-date=12 June 2023}} Using Dragon, the station will be capable of sustaining 4-crew missions with 24/7 communication facilities, up to 1,000 watts of power, up to 150 kg of preloaded cargo mass, and science, research, and in-space manufacturing opportunities for up to 30 days.{{Cite web |url=https://travelandleisure.com/spacex-space-station-vast-7498165 |first=Alison |last=Fox |date=15 May 2023 |publisher=Travel + Leisure |title=SpaceX Just Revealed Plans to Launch Its First Commercial Space Station — and You Can Reserve Your Seat Now |access-date=12 June 2023}}

The crews aboard the station will also conduct experiments in an attempt to mimic lunar gravity.{{Cite web |url=https://www.fool.com/investing/2023/05/20/private-space-stations-are-coming-in-2025/ |first=Rich |last=Smith |date=20 May 2023 |publisher=The Motley Fool |title=Private Space Stations Are Coming in 2025 |access-date=12 June 2023}}
