Haven-1 is a planned space station in low Earth orbit that is currently in development by American aerospace company Vast. [1] The station is expected to launch no earlier than August 2025 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. [2] More launches are expected to occur using Crew Dragon to shuttle astronauts to and from Haven-1 over the course of its lifespan. [3]
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. [4] 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. [5]
The crews aboard the station will also conduct experiments in an attempt to mimic the amount of gravity the Moon has. [6]
Haven-1's propulsion system is being built and provided by Impulse Space. [7] The propulsion system will consist of a storable propellant combination, nitrous oxide and ethane, propellant tanks, fluid lines, valves, sensors, control electronics and software, and Saiph thrusters as a reaction control thruster. [8] The station will also contain a dome for photography and viewing of the Earth for tourists, in addition to always-on internet through onboard Wi-Fi and resting rooms. [9]
In mid-February, Vast announced that it was partnering with El Segundo-based company AnySignal, Irvine-based company TRL11, and Singaporean company Addvalue for the providing of radio frequency and Inter-satellite Data Relay System (IDRS) connectivity, as well as advanced onboard video solutions for use in Haven-1.

Spacecraft propulsion is any method used to accelerate spacecraft and artificial satellites. In-space propulsion exclusively deals with propulsion systems used in the vacuum of space and should not be confused with space launch or atmospheric entry.
In spacecraft propulsion, a Hall-effect thruster (HET) is a type of ion thruster in which the propellant is accelerated by an electric field. Hall-effect thrusters are sometimes referred to as Hall thrusters or Hall-current thrusters. Hall-effect thrusters use a magnetic field to limit the electrons' axial motion and then use them to ionize propellant, efficiently accelerate the ions to produce thrust, and neutralize the ions in the plume. The Hall-effect thruster is classed as a moderate specific impulse space propulsion technology and has benefited from considerable theoretical and experimental research since the 1960s.
An ion thruster, ion drive, or ion engine is a form of electric propulsion used for spacecraft propulsion. An ion thruster creates a cloud of positive ions from a neutral gas by ionizing it to extract some electrons from its atoms. The ions are then accelerated using electricity to create thrust. Ion thrusters are categorized as either electrostatic or electromagnetic.
A spacecraft is a vehicle that is designed to fly in outer space and operate there. Spacecraft are used for a variety of purposes, including communications, Earth observation, meteorology, navigation, space colonization, planetary exploration, and transportation of humans and cargo. All spacecraft except single-stage-to-orbit vehicles cannot get into space on their own, and require a launch vehicle.
The Variable Specific Impulse Magnetoplasma Rocket (VASIMR) is an electrothermal thruster under development for possible use in spacecraft propulsion. It uses radio waves to ionize and heat an inert propellant, forming a plasma, then a magnetic field to confine and accelerate the expanding plasma, generating thrust. It is a plasma propulsion engine, one of several types of spacecraft electric propulsion systems.
A plasma propulsion engine is a type of electric propulsion that generates thrust from a quasi-neutral plasma. This is in contrast with ion thruster engines, which generate thrust through extracting an ion current from the plasma source, which is then accelerated to high velocities using grids/anodes. These exist in many forms. However, in the scientific literature, the term "plasma thruster" sometimes encompasses thrusters usually designated as "ion engines".
A cold gas thruster is a type of rocket engine which uses the expansion of a pressurized gas to generate thrust. As opposed to traditional rocket engines, a cold gas thruster does not house any combustion and therefore has lower thrust and efficiency compared to conventional monopropellant and bipropellant rocket engines. Cold gas thrusters have been referred to as the "simplest manifestation of a rocket engine" because their design consists only of a fuel tank, a regulating valve, a propelling nozzle, and the little required plumbing. They are the cheapest, simplest, and most reliable propulsion systems available for orbital maintenance, maneuvering and attitude control.
Gaganyaan is an Indian crewed orbital spacecraft intended to be the formative spacecraft of the Indian Human Spaceflight Programme. The spacecraft is being designed to carry three people, and a planned upgraded version will be equipped with rendezvous and docking capabilities. In its maiden crewed mission, the Indian Space Research Organisation (ISRO)'s largely autonomous 5.3-metric ton capsule will orbit the Earth at 400 km altitude for up to seven days with a two- or three-person crew on board. The first crewed mission was originally planned to be launched on ISRO's LVM3 rocket in December 2021. As of October 2023, it is expected to be launched by 2025.
The SpaceX Draco is a hypergolic liquid rocket engine designed and built by SpaceX for use in their space capsules. Two engine types have been built to date: Draco and SuperDraco.
The Boeing Starliner is a class of two partially reusable spacecraft designed to transport crew to the International Space Station (ISS) and other low-Earth-orbit destinations. It is manufactured by Boeing, with the Commercial Crew Program (CCP) of NASA as the anchor customer. The spacecraft consists of a reusable crew capsule and an expendable service module.
Since the founding of SpaceX in 2002, the company has developed four families of rocket engines — Merlin, Kestrel, Draco and SuperDraco — and is currently developing another rocket engine: Raptor, and after 2020, a new line of methalox thrusters.
Dragon 2 is a class of partially reusable spacecraft developed and manufactured by American aerospace manufacturer SpaceX, primarily for flights to the International Space Station (ISS). SpaceX also launches private missions, such as Inspiration4 and Axiom Space Missions. There are two variants of the Dragon spacecraft: Crew Dragon, a spacecraft capable of ferrying four crewmembers, and Cargo Dragon, a replacement for the original Dragon 1 used to carry freight to and from space. The spacecraft consists of a reusable space capsule and an expendable trunk module. The spacecraft launches atop a Falcon 9 Block 5 rocket and the capsule returns to Earth through splashdown.
SuperDraco is a hypergolic propellant rocket engine designed and built by SpaceX. It is part of the SpaceX Draco family of rocket engines. A redundant array of eight SuperDraco engines provides fault-tolerant propulsion for use as a launch escape system for the SpaceX Dragon 2, a passenger-carrying space capsule.
NASA's Pathfinder Technology Demonstrator (PTD) Project is a series of tech demonstrations of technologies aboard a series of nanosatellites known as CubeSats, providing significant enhancements to the performance of these versatile spacecraft. Each of the five planned PTD missions consist of a 6-unit (6U) CubeSat with expandable solar arrays.
Starship HLS is a lunar lander variant of the Starship spacecraft that is slated to transfer astronauts from a lunar orbit to the surface of the Moon and back. It is being designed and built by SpaceX under the Human Landing System contract to NASA as a critical element of NASA's Artemis program to land a crew on the Moon.
The Commercial Crew Program (CCP) provides commercially operated crew transportation service to and from the International Space Station (ISS) under contract to NASA, conducting crew rotations between the expeditions of the International Space Station program. American space manufacturer SpaceX began providing service in 2020, using the Crew Dragon spacecraft, and NASA plans to add Boeing when its Boeing Starliner spacecraft becomes operational no earlier than 2025. NASA has contracted for six operational missions from Boeing and fourteen from SpaceX, ensuring sufficient support for ISS through 2030.
Crew Dragon C204 was part of Crew Dragon flight vehicle SN 2-1 manufactured and operated by SpaceX and used by NASA's Commercial Crew Program. Used in the uncrewed Demo-1 mission, it was launched atop a Falcon 9 rocket on 2 March 2019, arriving at the International Space Station on 3 March 2019. It was the first orbital test flight of the Dragon 2 spacecraft. The spacecraft was unexpectedly destroyed on 20 April 2019 during a separate test when firing the SuperDraco engines at Landing Zone 1.
Impulse Space was founded in 2021 by Tom Mueller, employee No.1 at SpaceX and engineer of the Merlin and Draco rocket engines that power the Falcon9 and Dragon spacecraft. The company develops in-space transportation services for satellites that fly to Low Earth Orbit then need to reach other orbits.
