MAY 10, 2023
LONG BEACH, CALIFORNIA
SCHEDULED TO BE THE WORLD’S FIRST COMMERCIAL SPACE STATION, HAVEN-1 AND SUBSEQUENT HUMAN SPACEFLIGHT MISSIONS WILL ACCELERATE ACCESS TO SPACE EXPLORATION.
LONG BEACH, Calif. — May 10, 2023 — Vast, a pioneer in space habitation technologies, announced today their plans to launch the world’s first commercial space station, called Haven-1. Scheduled to launch on a SpaceX Falcon 9 rocket to low-Earth orbit no earlier than August 2025, Haven-1 will initially act as an independent crewed space station prior to being connected as a module to a larger Vast space station currently in development. The mission will be quickly followed by Vast-1, the first human spaceflight mission to Haven-1 on a SpaceX Dragon spacecraft. The vehicle and its four-person crew will dock with Haven-1 for up to 30 days while orbiting Earth. Vast also secured an option with SpaceX for an additional human spaceflight mission to Haven-1.
This represents the first time in history that a commercial space station company has both a contracted launch for its space station and a visiting human spaceflight mission.
“Vast is thrilled to embark on this journey of launching the world's first commercial space station, Haven-1, and its first crew, Vast-1,” said Jed McCaleb, CEO of Vast. “We are grateful to SpaceX for this exciting partnership that represents the first steps in Vast’s long-term vision of launching much larger, artificial gravity space stations in Earth orbit and beyond.”
“A commercial rocket launching a commercial spacecraft with commercial astronauts to a commercial space station is the future of low-Earth orbit, and with Vast we’re taking another step toward making that future a reality,” said Tom Ochinero, Senior Vice President of Commercial Business at SpaceX. “The SpaceX team couldn’t be more excited to launch Vast’s Haven-1 and support their follow-on human spaceflight missions to the orbiting commercial space station.”
Vast’s long-term goal is to develop a 100-meter-long multi-module spinning artificial gravity space station launched by SpaceX’s Starship transportation system. In support of this, Vast will explore conducting the world’s first spinning artificial gravity experiment on a commercial space station with Haven-1.
Vast is selling up to four crewed seats on the inaugural mission to Haven-1. Expected customers include domestic and international space agencies and private individuals involved in science and philanthropic projects. Visit vastspace.com/reserve for more details.
SpaceX will also provide crew training on Falcon 9 and the Dragon spacecraft, emergency preparedness, spacesuit and spacecraft ingress and egress exercises, as well as partial and full mission simulations including docking and undocking with Haven-1 for return to Earth.

That would make sense but limits the share of Earth surface which is visible for the crew.

Edit: Also should include this, seems that Dragon will be helping out with the life support onboard stationQuoteThe partnership with SpaceX is the key to making this mission happen. Not only will the 3.8-meter-wide Haven-1 module launch inside a Falcon 9 rocket, but part of its life-support systems will also be provided by the Crew Dragon spacecraft when the vehicle is docked.

Makes sense to have it at ISS inclination, means all of the Dragon flight paths abort/recovery zones etc are the same as for an ISS launch and are already well-established.

This weight estimate is not much more than the Crew Dragon (12,500 kg on Wikipedia) without the limitations of a crew launch trajectory could these even be a RTLS?
A space station with a RTLS would really be something. -

This suspiciously looks like Dragon XL, but could be different.

Probably quite different. Among other things, Dragon XL needs to have an "active mode" IDSS port, while Haven-1 needs to have a "passive mode" IDSS port. While an "active/passive" port is possible, the active-mode HW is somewhat complex and heavy. And that's just the end of the RPOD. Dragon XL must be the active spacecraft for the entire RPOD, with an appropriate set of thrusters and software. -

I don't know about that, but it does look like SpaceX was helping or at very least inspiring aspects of the design. -

I would describe this as cool and interesting, but aspirational, immature, and unlikely.
The video clip show Haven-1 firing attitude control thrusters.
However, it is not clear how these would be refueled.
On the ISS this function is primarily served by Progress vehicles, which bring fuel, and with their constant presence serve to both reboost the ISS and to desaturate the momentum storing devices, which there are Control Moment Gyros (CMGs).
With a single docking port Vast needs some alternative way to bring fuel, perhaps transferring something from the trunk of the Dragon to the exterior of Haven-1.
A 500 km orbit will reduce the need for reboosting, but will increase the frequency of Collision Avoidance Maneuvers (CAMs).
While Dragon can serve this purpose while attached, there has to be some system for doing this in the intervals when it is not, but there is no such system visible. This will increase the need to refuel the thrusters.
Not only will there be more CAMs than at the ~415 km altitude of the ISS, but there will be a lot more impacts from small, untrackable debris.
They can't leave that "Vistadome" exposed on the end.
Haven-1 may need some Whipple shields over much of the exterior, too.
The solar panels appear to be fixed with respect to the body of Haven.
They might have one degree of freedom, rotation about the hinge, but even Blue Reef went away from that, finally adding a second degree of freedom.
Speaking of Blue Reef's solar panels, no thermal radiator is shown.
Maybe they can get away with a flush panel like Crew Dragon, but that would go against shielding the exterior and be quite limited.
And rotating for simulating "lunar gravity"?
The video suggests this rotation would be axial.
Let's suppose that's for berths just inside the pressure vessle, which would be at most 2 meters from the axis.
w=sqrt(1.625 m/s²/2m)=0.9/sec
so it would have to rotate in 2*pi/0.9=7.0 sec or almost 9 RPM.
Doesn't that seem pretty fast?
And wouldn't it be hard to maintain rotation about the axis with the smallest moment of inertial?
Meanwhile the power generation would be reduced by a factor of 2*Pi and any thermal radiators might get sunlight on them.Makes sense to have it at ISS inclination, means all of the Dragon flight paths abort/recovery zones etc are the same as for an ISS launch and are already well-established.
I disagree. The 51.6 degrees inclination of the ISS is specifically to overfly the launch site for Soyuz and Progress, and comes at significant expense in terms of launch capacity, weather restrictions for aborts, days of contunuous solar illumination which would get worse at 500 km, and others. Given all the stuff Vast has to design, designing new abort scenarios is a minor addition.
I truly wish Vast luck in their endeavors, but am not adding these flights to the my personal version of the manifest.
edit: I was unaware, or forgot that there is an existing thread on the Vast station. -

SPACEX TO LAUNCH VAST’S COMMERCIAL SPACE STATION AND FIRST HUMAN SPACEFLIGHT MISSION
Vast announced today that SpaceX will launch what is expected to be the world’s first commercial space station, known as Vast Haven-1, quickly followed by two human spaceflight missions to said space station. Scheduled to launch on a Falcon 9 rocket to low-Earth orbit no earlier than August 2025. Haven-1 will be a fully-functional independent space station and eventually be connected as a module to a larger Vast space station currently in development.
Upon launch of Haven-1, Falcon 9 will launch Vast’s first human spaceflight mission to the commercial space station, Vast-1. Dragon and its four-person crew will dock with Haven-1 for up to 30 days while orbiting Earth. Vast also secured an option for an additional human spaceflight mission to the station aboard a Dragon spacecraft.
The Vast-1 crew selection process is underway and the crew will be announced at a future date. Once finalized, SpaceX will provide crew training on Falcon 9 and the Dragon spacecraft, emergency preparedness, spacesuit and spacecraft ingress and egress exercises, as well as partial and full mission simulations including docking and undocking for return to Earth.
Vast’s long-term goal is to develop a 100-meter-long multi-module spinning artificial gravity space station launched by SpaceX’s Starship transportation system. In support of this, Vast will explore conducting the world’s first spinning artificial gravity experiment on a commercial space station with Haven-1.
This new partnership between Vast and SpaceX will continue to create and accelerate greater accessibility to space and more opportunities for exploration on the road to making humanity multiplanetary. -

I assumed that they intend to put it into the same plane as ISS to allow the crew of each station to use the other station as an emergency refuge with a minimal delta-V maneuver.Makes sense to have it at ISS inclination, means all of the Dragon flight paths abort/recovery zones etc are the same as for an ISS launch and are already well-established.

I suspect Haven will be much like Skylab, fully fueled for its operational lifetime at launch. Yeah, that dome is definitely going to have to have a MMOD cover.
However, keep in mind, Haven is not the end game for Vast - they are planning a much, much larger space station. This is likely to end up being like Tiangong 1/2, a precursor module visited only a few times before they launch the big multimodule space station. -

twitter.com/rocketrepreneur/status/1656395197847334912QuoteAgreed. I don't think what they're trying to do is particularly crazy. The timeline is ambitious, but it looks like they may be trying to leverage a lot of subsystems from SpaceX's Dragon for this first module.

One of the reasons to really like this concept is it's lack of ambition. That's a good thing! All of the mega-amazing designs for complex orbital facilities serviced by spaceplanes look great in renders, but are unlikely to ever be funded and/or technically feasible with current level technology. This one looks very doable, which means still challenging and the possibility of failure is high (space is hard), but achievable. Only requires two regular-stick F9 launches to make use of it at least one time is nice too, that's about as cheap from a launch perspective as you can get.
