The Space Rider (Space Reusable Integrated Demonstrator for Europe Return) is a planned uncrewed orbital lifting body spaceplane aiming to provide the European Space Agency (ESA) with affordable and routine access to space. [5] [6] [7] Contracts for construction of the vehicle and ground infrastructure were signed in December 2020. [8] Its maiden flight is currently scheduled for the third quarter of 2025. [4]
Development of Space Rider is being led by the Italian Programme for Reusable In-orbit Demonstrator in Europe (PRIDE programme) in collaboration with ESA, and is the continuation of the Intermediate eXperimental Vehicle (IXV) experience, [2] [9] launched on 11 February 2015. The cost of this phase, not including the launcher, is at least US$36.7 million. [10] At the ESA Ministerial Council held in Seville in November 2019, the development of the Space Rider was subscribed by the participating member states with an allocation of €195.73 million. [11]
The European Space Agency has a program called Future Launchers Preparatory Programme (FLPP), which made a call for submissions for a reusable spaceplane. [12] One of the submissions was by the Italian Space Agency, that presented their own Programme for Reusable In-orbit Demonstrator in Europe (PRIDE programme) which went ahead to develop the precursor called Intermediate eXperimental Vehicle (IXV) and the resulting Space Rider. [2]
Funding was initially approved by the ESA in 2016, with the project to be led by the Italian Aerospace Research Centre (CIRA). [10] Thales Alenia Space and Lockheed Martin were tasked with completing the design by 2019. In November 2017, the ESA approved funding to Thales Alenia Space and Avio to build reentry and service modules, respectively. [13] In late November 2019, the project was fully approved by ESA and will be funded mostly by Italy, [14] [15] and in December 2020, ESA signed contracts with co-prime contractors Thales Alenia Space and Avio for delivery of the Space Rider flight model, which in turn manage a consortium of more than 20 European companies operating in the space sector. [2] The Italian Space Agency (ASI) subsequently contracted with Virgin Galactic for a suborbital research flight on SpaceShipTwo for research related to Space Rider. [16] The first flight of Space Rider is currently scheduled for the third quarter of 2025. [4]
In April 2018, ESA released an Announcement of Opportunity (AoO) to fly small payloads on Space Rider's maiden flight. [17] By June 2019, the project was advancing towards the Critical Design Review (CDR) at the end of 2019. [7] An industrial reorganisation followed the ESA Ministerial Council held in 2019. To deal with it a design bridging phase was put in place with the System CDR planned in mid-2022. [1]
On completion of the two-month long maiden mission, Space Rider will return to Earth with the payloads stowed in its cargo bay. [17] This qualification flight of Space Rider will take place in 2025 [4] followed by several missions to demonstrate a range of capabilities and orbits, before handing over the project to the private sector. [18]
By 2025, the ESA plans to privatise the Space Rider, with Arianespace the likely operator. [19]
On June 20 2023, the Space Rider programme proceeded into Phase D of its development, allowing qualification and production to commence. [20]
The Space Rider design inherits technology developed for the earlier Intermediate eXperimental Vehicle, also within the Programme for Reusable In-orbit Demonstrator in Europe (PRIDE). [2] [10] [13] The design team considered the trade-offs of using only a lifting body and also using optional wings or vertical fins. [9] It was then decided in 2017 that the design should optimise the internal volume of the Vega rocket fairing, so its aerodynamic shape will be a simple lifting body, as tested on its predecessor, the IXV. [9] 3-axis control is achieved by the use of rear flaps. [9]
Space Rider will have the potential to allow experiments in microgravity, such as exposure of materials to outer space and in-orbit validation of technologies, as well as deployment of small satellites. [17]
In 2019, some parafoil guided landing tests will[ needs update ] be performed by dropping a full-scale model from helicopters or balloons. [10]
Space Rider is designed to launch atop the Vega-C launch vehicle from Guiana Space Centre. [4] The spacecraft is being designed to conduct missions up to two months long in low Earth orbit with up to 600 kg [1] of cargo. [3] [21] The re-entry module itself is a testbed for entry technologies as the IXV precursor was, so future improvements are envisioned, [22] including point-to-point flights, even "space tourism". [10]
Activities for Phase-B2/C, covering the Preliminary Design Review (PDR) started on 25 January 2018, [23] and the Critical Design Review (CDR) begin in late 2019. [7] An industrial reorganisation followed the ESA Ministerial Council held in 2019. To deal with it a design bridging phase was put in place with the System CDR planned in mid-2022. [1]
Space Rider's service module is a modified version of the Vega-C AVUM+, which will extend the time that can be spent in orbit by at least two months before Space Rider returns with its cargo to Earth to land on the ground. [24] The service module will provide power, attitude control and deorbit capability, and it will separate from the spacecraft just before atmospheric reentry. [7]
Upon atmospheric entry, the lifting body shape will decelerate the spacecraft to subsonic speed (below Mach 0.8), when one or two drogue parachute will be deployed at about 15–12 km altitude to slow it further (to Mach 0.18 - 0.22) [21] Then, a controllable gliding parachute called parafoil will be deployed to begin the controlled descent phase for a nearly horizontal touchdown (≈35 m/s) using no wheels. [21] The landing concept is similar to the NASA X-38 landing system. [21]
The baseline landing site is the Guiana Space Centre. [1] For orbits with inclination >37°, landings could be performed at the Portuguese Santa Maria Island in the Azores archipelago.

A lifting body is a fixed-wing aircraft or spacecraft configuration in which the body itself produces lift. In contrast to a flying wing, which is a wing with minimal or no conventional fuselage, a lifting body can be thought of as a fuselage with little or no conventional wing. Whereas a flying wing seeks to maximize cruise efficiency at subsonic speeds by eliminating non-lifting surfaces, lifting bodies generally minimize the drag and structure of a wing for subsonic, supersonic and hypersonic flight, or spacecraft re-entry. All of these flight regimes pose challenges for proper flight safety.
The Automated Transfer Vehicle, originally Ariane Transfer Vehicle or ATV, was an expendable cargo spacecraft developed by the European Space Agency (ESA), used for space cargo transport in 2008–2015. The ATV design was launched to orbit five times, exclusively by the Ariane 5 heavy-lift launch vehicle. It effectively was a larger European counterpart to the Russian Progress cargo spacecraft for carrying upmass to a single destination—the International Space Station (ISS)—but with three times the capacity.
Hermes was a proposed spaceplane designed by the French Centre National d'Études Spatiales (CNES) in 1975, and later by the European Space Agency (ESA). It was superficially similar to the American Boeing X-20 Dyna-Soar and the larger Space Shuttle.
A reusable launch vehicle has parts that can be recovered and reflown, while carrying payloads from the surface to outer space. Rocket stages are the most common launch vehicle parts aimed for reuse. Smaller parts such as rocket engines and boosters can also be reused, though reusable spacecraft may be launched on top of an expendable launch vehicle. Reusable launch vehicles do not need to make these parts for each launch, therefore reducing its launch cost significantly. However, these benefits are diminished by the cost of recovery and refurbishment.
Vega is an expendable launch system in use by Arianespace jointly developed by the Italian Space Agency (ASI) and the European Space Agency (ESA). Development began in 1998 and the first launch took place from the Guiana Space Centre on 13 February 2012.
A spaceplane is a vehicle that can fly and glide like an aircraft in Earth's atmosphere and maneuver like a spacecraft in outer space. To do so, spaceplanes must incorporate features of both aircraft and spacecraft. Orbital spaceplanes tend to be more similar to conventional spacecraft, while sub-orbital spaceplanes tend to be more similar to fixed-wing aircraft. All spaceplanes to date have been rocket-powered for takeoff and climb, but have then landed as unpowered gliders.
The Boeing X-37, also known as the Orbital Test Vehicle (OTV), is a reusable robotic spacecraft. It is boosted into space by a launch vehicle, then re-enters Earth's atmosphere and lands as a spaceplane. The X-37 is operated by the Department of the Air Force Rapid Capabilities Office, in collaboration with United States Space Force, for orbital spaceflight missions intended to demonstrate reusable space technologies. It is a 120-percent-scaled derivative of the earlier Boeing X-40. The X-37 began as a NASA project in 1999, before being transferred to the United States Department of Defense in 2004. Until 2019, the program was managed by Air Force Space Command.
Hopper was a proposed European Space Agency (ESA) orbital spaceplane and reusable launch vehicle. The Hopper was a FESTIP system study design.
The Advanced Reentry Demonstrator (ARD) was a European Space Agency (ESA) suborbital reentry vehicle. It was developed and operated for experimental purposes, specifically to validate the multiple reentry technologies integrated upon it and the vehicle's overall design, as well as to gain greater insight into the various phenomenon encountered during reentry.

The Intermediate eXperimental Vehicle (IXV) is a European Space Agency (ESA) experimental suborbital re-entry vehicle. It was developed to serve as a prototype lifting body orbital return vehicle to validate the ESA's work in the field of reusable orbital return vehicles.
Thales Alenia Space is a joint venture between the French technology corporation Thales Group (67%) and Italian defense conglomerate Leonardo (33%). The company is headquartered in Cannes, France.
The Future Launchers Preparatory Programme (FLPP) is a technology development and maturation programme of the European Space Agency (ESA). It develops technologies for the application in future European launch vehicles (launchers) and in upgrades to existing launch vehicles. By this it helps to reduce time, risk and cost of launcher development programmes.
Started in 2004, the programmes initial objective was to develop technologies for the Next Generation Launcher (NGL) to follow Ariane 5. With the inception of the Ariane 6 project, the focus of FLPP was shifted to a general development of new technologies for European launchers.
FLPP develops and matures technologies that are deemed promising for future application but currently do not have a sufficiently high technology readiness level (TRL) to allow a clear assessment of their performance and associated risk. Those technologies typically have an initial TRL of 3 or lower. The objective is to raise the TRL up to about 6, thus creating solutions which are proven under relevant conditions and can be integrated into development programmes with reduced cost and limited risk.
The Italian Aerospace Research Centre is a consortium established in July 1984 to promote the growth and success of the aerospace industry in Italy. The majority of CIRA share capital is held by government organizations: the Italian Space Agency (ASI) and the National Research Council of Italy.
