Space Rider

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.ESA's reusable Space RIDER capsule would carry equipment to orbit and back

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, launched on 11 February 2015. The cost of this phase, not including the launcher, is at least US$36.7 million. 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.

History

The European Space Agency has a program called Future Launchers Preparatory Programme (FLPP), which made a call for submissions for a reusable spaceplane. 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.

Funding was initially approved by the ESA in 2016, with the project to be led by the Italian Aerospace Research Centre (CIRA). 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. In late November 2019, the project was fully approved by ESA and will be funded mostly by Italy, 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. The Italian Space Agency (ASI) subsequently contracted with Virgin Galactic for a suborbital research flight on SpaceShipTwo for research related to Space Rider. The first flight of Space Rider is currently scheduled for late 2024.

In April 2018, ESA released an Announcement of Opportunity (AoO) to fly small payloads on Space Rider's maiden flight. By June 2019, the project was advancing towards the Critical Design Review (CDR) at the end of 2019. 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.

On completion of the two-month long maiden mission, Space Rider will return to Earth with the payloads stowed in its cargo bay. This qualification flight of Space Rider will take place in 2024 followed by several missions to demonstrate a range of capabilities and orbits, before handing over the project to the private sector. By 2025, the ESA plans to privatise the Space Rider, with Arianespace the likely operator.

Design

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). The design team considered the trade-offs of using only a lifting body and also using optional wings or vertical fins.
