* Orbit Fab's first depot, called Tanker-001 Tenzing, is scheduled to launch in 2023.

* The depot will store water, which can be used as fuel for spacecraft.

* Orbit Fab is also developing a depot that will store cryogenic fuels, such as liquid oxygen and liquid hydrogen, which can be used for more powerful rockets.

Orbit Fab's depots will be located in high Earth orbit, where they will be accessible to a variety of spacecraft. The depots will be equipped with robotic arms that will allow them to refuel spacecraft without the need for human intervention.

The ability to refuel spacecraft in orbit will have a number of benefits. It will allow satellites to extend their missions, and it will make it possible for spacecraft to travel to more distant locations. It will also reduce the cost of space missions by eliminating the need to launch large amounts of fuel into space.

Orbit Fab is one of several companies that are developing space fuel depots. Other companies include Airbus, Boeing, and Lockheed Martin. The development of space fuel depots is a key step in the development of a space-based economy.
