Orbital Express Launch Ltd., or Orbex, is a United Kingdom-based [4] aerospace company that is developing a small commercial orbital rocket called Prime. Orbex is headquartered in Forres, Moray, in Scotland and has subsidiaries in Denmark and Germany. Orbex may build its future launch complex, Sutherland spaceport, on the A' Mhòine peninsula in the county of Sutherland, northern Scotland, if and when deemed necessary. [5] [6]
The company was founded in 2015 as Moonspike Ltd., with the goal of crowdfunding a private spacecraft mission to the Moon. [7] A Kickstarter campaign running from 1 October to 1 November 2015 raised less than £79,000 out of a goal of £600,000, rendering Moonspike ineligible for the funds. [8] Moonspike was renamed Orbital Express Launch Ltd. in 2016, with the company now aiming to provide commercial launch services of nano- and microsatellites, especially CubeSats, to polar and Sun-synchronous low Earth orbits. [9] In July 2018, Orbex secured £30 million in public and private funding for the development of its orbital rocket system, named Prime. [1] [10] In October 2022 Orbex closed a £40.4 million Series C funding round. [11] [12] Orbex has opened a factory for Prime in Forres, Scotland that employs 150 people. [3] Currently, the company is working on developing the Prime vehicle, while preparing for the initial launch from SaxaVord Spaceport. [5]
Orbex initially intended to share the Sutherland spaceport in northern Scotland with Lockheed Martin, who at the time did not have a launch vehicle, but their strategic shareholding in Rocket Lab led to speculation that they would launch with the Rocket Lab Electron rocket, but since the two vehicles (Electron and Prime) use different propellants, the two companies would have separate launch pads while sharing some common infrastructure. The planning application for the site, however, includes only one launchpad. Lockheed Martin then moved their launch plans to a competing site, SaxaVord Spaceport, in the Shetland Isles. [1] [13] [14] Orbex also plans to launch from a future spaceport in the Portuguese Azores. [15] [16]
In April 2024, it was reported that the company received $20.7 million in a Series D funding round, with the bulk of the funds going towards development of the Prime launch vehicle. [17] In November 2024, Orbex announced that the first launch of Prime would be conducted from SaxaVord Spaceport instead of Sutherland. [5]

Orbex is currently developing a light launch vehicle called Prime,and its booster (first stage) is planned to be reusable. [18] [19] The rocket's diameter is 1.45 m (4 ft 9 in), [20] and will use a non-toxic bi-propellant consisting of liquid oxygen and propane. One cited advantage of using propane is that it remains liquid at cryogenic temperatures,which enables a design where a central carbon-fibre tank of propane is surrounded by an outer tank of liquid oxygen,creating a light structural mass. [1] First stage reuse is planned to be achieved by a combination of a parachute and four ‘petals’which will fold out prior to atmospheric reentry to induce drag and passively reorient the vehicle. [21] It will be capable of launching payloads up to 150 kilograms (330 lb) to a standard 500 km Sun-synchronous orbit. [1] [19]
The maiden flight of Prime is expected to occur in 2025, [3] subject to the availability of SaxaVord Spaceport and a Civil Aviation Authority launch licence, [22] for Surrey Satellite Technology Ltd. [3] [23] Orbex also announced it was chosen by nanosatellite startup Astrocast to launch their communications satellites. [24]
Unst is one of the North Isles of the Shetland Islands,Scotland. It is the northernmost of the inhabited British Isles and is the third-largest island in Shetland after Mainland and Yell. It has an area of 46 sq mi (120 km2).
Remote Radar Head Saxa Vord or RRH Saxa Vord,is a Royal Air Force radar station located on the island of Unst,the most northern of the Shetland Islands in Scotland. As of July 2019 it is once more a fully operational radar station,after closure in 2006. The station's motto Praemoneo de Periculis reflects its role. RAF Saxa Vord is further north than Saint Petersburg in Russia,and on the same latitude as Anchorage,Alaska. The station was named after Saxa Vord,which is the highest hill on Unst at 935 ft (285 m). It holds the unofficial British record for wind speed,which in 1992 was recorded at 197 mph (317 km/h) —just before the measuring equipment blew away.

A space tug is a type of spacecraft used to transfer spaceborne cargo from one orbit to another orbit with different energy characteristics. The term can include expendable upper stages or spacecraft that are not necessarily a part of their launch vehicle. However,it can also refer to a spacecraft that transports payload already in space to another location in outer space,such as in the Space Transportation System concept. An example would be moving a spacecraft from a low Earth orbit (LEO) to a higher-energy orbit like a geostationary transfer orbit,a lunar transfer,or an escape trajectory.
Electron is a two-stage,partially reusable orbital launch vehicle developed by Rocket Lab,an American aerospace company with a wholly owned New Zealand subsidiary. Electron services the commercial small satellite launch market. It's the third most launched small-lift launch vehicle in history. Its Rutherford engines are the first electric-pump-fed engine to power an orbital-class rocket. Electron is often flown with a kickstage or Rocket Lab's Photon spacecraft. Although the rocket was designed to be expendable,Rocket Lab has recovered the first stage twice and is working towards the capability of reusing the booster. The Flight 26 (F26) booster has featured the first helicopter catch recovery attempt. Rocket Lab has,however,abandoned the idea of catching Electron.
Vector Launch,Inc. is an American space technology company which aims to launch suborbital and orbital payloads. Vector Launch declared bankruptcy in December 2019 and re-emerged in October 2020.
Relativity Space Inc. is an American aerospace manufacturing company headquartered in Long Beach,California. Relativity Space is developing manufacturing technologies,launch vehicles,and rocket engines for commercial orbital launch services. The company is notable for manufacturing most of their Terran 1 and Terran R rocket parts using 3D printing. As of April 2024,Terran R is on track for initial launch in 2026.
The Sutherland spaceport,also known as Space Hub Sutherland or UK Vertical Launch (UKVL) Sutherland,is a planned spaceport to be located in Sutherland in Scotland. It would be one of the first vertical launch capable spaceports in the United Kingdom,and operated by a commercial entity. The spaceport is intended to support the Orbex Prime launch vehicle. The spaceport will be located on the A' Mhòine peninsula northwest of Tongue village,Sutherland,Scotland. Groundbreaking occurred on 5 May 2023. In December 2024,Orbex announced that the project had been put on hold.

SaxaVord Spaceport,previously known as Shetland Space Centre,is a UK spaceport located on the Lamba Ness peninsula on Unst,the most northerly of the inhabited Shetland Islands off the coast of Scotland. The site is near the RAF Saxa Vord radar station and the settlement of Skaw.
A floating launch vehicle operations platform is a marine vessel used for launch or landing operations of an orbital launch vehicle by a launch service provider:putting satellites into orbit around Earth or another celestial body,or recovering first-stage boosters from orbital-class flights by making a propulsive landing on the platform.
Rocket Factory Augsburg AG (RFA) is a German NewSpace start-up located in Augsburg. It was founded in 2018 with the mission to build rockets just like cars. Its multistage rocket,RFA One,is currently under development. As of November 2023,it had been scheduled to launch during the summer of 2024;however,an anomaly during a first stage static fire test in August 2024 resulted in destruction of the stage,and the launch has been postponed.
