The Programme for Reusable In-orbit Demonstrator in Europe (PRIDE) is an Italian Space Agency programme that aims to develop a reusable robotic spaceplane named Space Rider in collaboration with the European Space Agency.
The PRIDE programme was approved at the ESA Ministerial Council in Naples, Italy on 21 November 2012 under the parent ESA programme called Future Launchers Preparatory Programme (FLPP). The Space Rider spaceplane will be similar to, but smaller and cheaper than, the Boeing X-37. It will be launched in 2025 [2] by the Vega C rocket, operate robotically in orbit, and land automatically on a runway. [3]
The European Space Agency has a program called Future Launchers Preparatory Programme (FLPP), which made a call for submissions for a reusable spaceplane. [4] [5] One of the submissions was by the Italian Space Agency, that presented their 'Programme for Reusable In-orbit Demonstrator in Europe' (PRIDE program) which went ahead to develop the prototype named Intermediate eXperimental Vehicle (IXV) and the consequential Space Rider spaceplane that inherits technology from its prototype IXV. [6]
The PRIDE programme was initially funded by the European Space Agency (ESA) on 21 November 2012, at the ESA Ministerial Council in Naples, Italy. [7] The project was created with the objective of creating a small uncrewed spaceplane that was also affordable and reusable. During the initial design stage the vehicle was referred to as PRIDE-ISV; the suffix ISV stands for Innovative Space Vehicle. The PRIDE development team began industrial activities in September 2015. The first launch of the Space Rider production spaceplane is expected around 2022. [8] [9]
The Intermediate eXperimental Vehicle (IXV) was developed to serve as a prototype spaceplane to validate ESA's preliminary work. It was launched on 11 February 2015 [10] [11] [12] and flown to 412 km (256 mi) altitude. It was then brought down under a parasail for a splashdown on the Pacific Ocean. [13]
With affordability in mind, the Space Rider spaceplane is based on technologies developed and tested on the IXV. [6] The Space Rider is also a lifting body without wings or vertical fins. For landing, it will deploy a parasail and land on a field. [14]
The Space Rider spaceplane will be capable of carrying a 300 kg payload into orbit. It will be equipped with solar panels, allowing for two months in-orbit operations. Vega will be used as a launch vehicle. [15]
The Space Rider will be used as an orbital test platform for re-usable launcher stages, Earth observation, robotic exploration, servicing of orbital infrastructures, and microgravity experiments. [6] [15]
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.
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.
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.
ASTOS is a tool dedicated to mission analysis, Trajectory optimization, vehicle design and simulation for space scenarios, i.e. launch, re-entry missions, orbit transfers, Earth observation, navigation, coverage and re-entry safety assessments. It solves Aerospace problems with a data driven interface and automatic initial guesses. Since 1989, with the support of the European Space Agency, it has developed, and improved this trajectory optimization environment to compute optimal trajectories for a variety of complex multi-phase Optimal control problems. ASTOS is being extensively used at ESA and aerospace industry community to calculate mission analysis, optimal launch and entry trajectories and was one of the tools used by ESA to assess the risk due to the ATV 'Jules Verne' re-entry. ASTOS is compatible with Windows and Linux platforms and is maintained and commercialized by Astos Solutions GmbH.
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.
Avatar is a concept study for a robotic single-stage reusable spaceplane capable of horizontal takeoff and landing, by India's Defence Research and Development Organisation. The mission concept is for low cost military and commercial satellite space launches.
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.
European eXPErimental Re-entry Test-bed (EXPERT) is a European Space Agency aerothermodynamics research programme. It was planned that vehicle will be launched on a Russian Volna launch vehicle and will provide knowledge and experience in the design and development of re-entry vehicles. As of 2012, one element in a European Space Agency push to develop vehicles capable of re-entry has been pushed back until at least 2013 as the agency seeks a launch alternative to the Russian submarine-launched Volna rocket which was withdrawn. One of its main goals was to test materials for ESA's Intermediate eXperimental Vehicle (IXV), an unmanned, delta-winged plane launched in 2015 aboard ESA's new Vega small-satellite launcher. Currently EXPERT remains in storage conditions in Turin.
The Crew Module Atmospheric Re-entry Experiment (CARE) is an experimental test vehicle for the Indian Space Research Organisation's future ISRO orbital vehicle called Gaganyaan. It was launched successfully on 18 December 2014 from the Second Launch Pad of the Satish Dhawan Space Centre, by a LVM3 designated by ISRO as the LVM 3X CARE mission. Total cost of mission was ₹155 crore. Cost of launch vehicle and CARE module was ₹140 crore and ₹15 crore.
The Space Rider is a planned uncrewed orbital lifting body spaceplane aiming to provide the European Space Agency (ESA) with affordable and routine access to space. Contracts for construction of the vehicle and ground infrastructure were signed in December 2020. Its maiden flight is currently scheduled for the third quarter of 2025.
Miura 5 is a two-stage European orbital recoverable launch vehicle currently under development by the Spanish company PLD Space. In a standard two-stage configuration, it will have a length of 34 m, be capable of inserting 1000 kg of payload into a low Earth orbit (LEO), featuring an optional kick stage that can circularize the orbits of satellites.
Atmospheric Reentry Experimental Spaceplane (ARES) is a robotic spaceplane concept. The project merged with the French Dassault Aviation VEHRA programme to produce a concept called Dassault Ares Spaceplane.
The Smart Upper Stage for Innovative Exploration (SUSIE) is a proposal for a reusable spacecraft designed by ArianeGroup. It is capable of manned operations, carrying up to five astronauts to low Earth orbit (LEO), or alternatively functioning as an automated freighter capable of delivering payloads of up to seven tons. It is envisioned to be launched on the Ariane 64 launch vehicle for European Space Agency (ESA) missions.
The Intermediate eXperimental Vehicle (IXV), under ESA's Future Launchers Preparatory Programme (FLPP), is the step forward from the successful Atmospheric Reentry Demonstrator flight in 1998, establishing Europe's role in this field.
It will navigate through the atmosphere within its reentry corridor before descending, slowed by a multistage parachute, for a safe splashdown in the Pacific Ocean some 100 minutes after liftoff.
