HERACLES (Human-Enhanced Robotic Architecture and Capability for Lunar Exploration and Science) is a planned robotic transport system to and from the Moon by Europe (ESA), Japan (JAXA) and Canada (CSA) that will feature a lander called the European Large Logistic Lander (EL3, or Argonaut), a Lunar Ascent Element, and a rover. [2] The lander can be configured for different operations such as up to 1.5 tons of cargo delivery, [3] sample-returns, or prospecting resources found on the Moon. [4]
The system is planned to support the Artemis program and perform lunar exploration using the Lunar Gateway space station as a staging point.
As of 2023, the HERACLES project has been superseded by the European Large Logistics Lander (EL3) project, and is no longer active. [5]
The HERACLES architecture was outlined by 2015. [6] ESA approved the HERACLES project in November 2019. [3] [7] Its first mission is expected to launch in 2030. [8] The project will be the next phase of ESA's exploration program Terrae Novae (known as European Exploration Envelope Programme (E3P) before 2021). [9]
The HERACLES transport system will leverage the Lunar Gateway as a staging point. [10] The architecture involves dispatching the EL3 lunar lander from Earth aboard an Ariane 64 [11] : slides 7, 9 and 10 [12] [2] which would land on the Moon with a disposable descent module.
The EL3 lander will have a landing mass of approximately 1,800 kg (4,000 lb) [13] and will be capable of transporting a Canadian robotic rover to explore, prospect potential resources, and load samples up to 15 kg (33 lb) on the ascent module. [14] The rover would then traverse several kilometers across the Schrödinger basin on the far side of the Moon to explore and collect more samples to load on the next EL3 lander. [15] [13] The ascent module would return each time to the Lunar Gateway, where it would be captured by the Canadian robotic arm and samples transferred to an Orion spacecraft for transport to Earth with the returning astronauts. [16] The ascent module would then be refueled and paired with a new descent module dispatched from Earth.
The second and third landings would each have 500 kg (1,100 lb) payload available for alternate uses such as testing new hardware, demonstrating technology and gaining experience in operations. The 4th or 5th lander mission will provide a sample return. [13]
The project will require the development of a reusable lunar ascent engine, four of which could be clustered to power a reusable crewed or robotic lander in the future. Later missions will include a pressurised rover driven by astronauts and an ascent module for the crew to return to Earth. [13] [16]
The key objectives of HERACLES include: [14]
The HERACLES EL3 lander concept will consist of the Lunar Descent Element (LDE), which will be provided by Japan's JAXA, [1] the ESA-built Interface Element that will house the rover, and the European Lunar Ascent Element (LAE) that will return the samples to the Lunar Gateway. [14]
The rover, to be developed by the Canadian Space Agency (CSA), will have a mass of 330 kg (730 lb) and will feature a "radioisotope power system" that will permit operations during the long and frigid lunar nights. [14] The total spacecraft mass will be ≈8,500 kg (18,700 lb) including fuel, with a payload of ≈1,500 kg (3,300 lb). [1]

Nammo have been awarded a contract to evaluate engine performance requirements and 'find' the best engine design. [17] The engine may be fed by electrically driven pumps, from low pressure propellant tanks, which may enable in-space refueling. [17]
A lander is a spacecraft that descends towards, then comes to rest on the surface of an astronomical body other than Earth. In contrast to an impact probe, which makes a hard landing that damages or destroys the probe upon reaching the surface, a lander makes a soft landing after which the probe remains functional.
A lunar lander or Moon lander is a spacecraft designed to land on the surface of the Moon. As of 2024, the Apollo Lunar Module is the only lunar lander to have ever been used in human spaceflight, completing six lunar landings from 1969 to 1972 during the United States' Apollo Program. Several robotic landers have reached the surface, and some have returned samples to Earth.
The physical exploration of the Moon began when Luna 2, a space probe launched by the Soviet Union, made a deliberate impact on the surface of the Moon on September 14, 1959. Prior to that the only available means of lunar exploration had been observations from Earth. The invention of the optical telescope brought about the first leap in the quality of lunar observations. Galileo Galilei is generally credited as the first person to use a telescope for astronomical purposes, having made his own telescope in 1609, the mountains and craters on the lunar surface were among his first observations using it.
The following outline is provided as an overview of and topical guide to space exploration.
A rover is a planetary surface exploration device designed to move over the rough surface of a planet or other planetary mass celestial bodies. Some rovers have been designed as land vehicles to transport members of a human spaceflight crew; others have been partially or fully autonomous robots. Rovers are typically created to land on another planet via a lander-style spacecraft,tasked to collect information about the terrain, and to take crust samples such as dust, soil, rocks, and even liquids. They are essential tools in space exploration.
SELENE-2, or the Selenological and Engineering Explorer 2, is a cancelled Japanese robotic mission to the Moon that would have included an orbiter, a lander and a rover. It was intended as a successor to the 2007 SELENE (Kaguya) lunar orbiter.
Planetary Transportation Systems (PTS), formerly known as PTScientists and Part-Time Scientists, is a Berlin-based aerospace company. They developed the robotic lunar lander "ALINA" and seek to land on the Moon with it. They became the first German team to officially enter the Google Lunar X-Prize competition on June 24, 2009, but failed to reach the finals in 2017 for lack of a launch contract. During the summer of 2019, the company filed for bankruptcy, and the ALINA project was put on hold. In July 2021, PTS was selected with ArianeGroup to build ESA's ASTRIS kick-stage.
A lunar rover or Moon rover is a space exploration vehicle designed to move across the surface of the Moon. The Apollo program's Lunar Roving Vehicle was driven on the Moon by members of three American crews, Apollo 15, 16, and 17. Other rovers have been partially or fully autonomous robots, such as the Soviet Union's Lunokhods, Chinese Yutus, Indian Pragyan, and Japan's LEVs. Five countries have had operating rovers on the Moon: the Soviet Union, the United States, China, India, and Japan.
The European System Providing Refueling Infrastructure and Telecommunications (ESPRIT) is an under construction module of the Lunar Gateway. It will provide refueling through additional xenon and hydrazine capacity for use in the Power and Propulsion Element's ion engines and hydrazine thrusters. It will also provide additional communications equipment, a habitation area, and storage. It will have a launch mass of approximately 10,000 kg (22,000 lb), a length of 6.4 m (21 ft), and a diameter of 4.6 m (15 ft). ESA awarded two parallel design studies for ESPRIT, one mostly led by Airbus in partnership with Comex and OHB and one led by Thales Alenia Space. The construction of the module was approved in November 2019. On 14 October 2020, Thales Alenia Space announced that they had been selected by ESA to build the ESPRIT module.
Chang'e 6 was the sixth robotic lunar exploration mission by the China National Space Administration (CNSA) and the second CNSA lunar sample-return mission. Like its predecessors in the Chinese Lunar Exploration Program, the spacecraft is named after the Chinese moon goddess Chang'e. It was the first lunar mission to retrieve samples from the far side of the Moon; all previous samples were collected from the near side.
The Lunar Gateway, or simply Gateway, is a space station which is planned to be assembled in orbit around the Moon. The Gateway is intended to serve as a communication hub, science laboratory, and habitation module for astronauts as part of the Artemis program. It is a multinational collaborative project: participants include NASA, the European Space Agency (ESA), the Japan Aerospace Exploration Agency (JAXA), the Canadian Space Agency (CSA), and the Mohammed Bin Rashid Space Centre (MBRSC). The Gateway is planned to be the first space station beyond low Earth orbit.
Martian Moons eXploration (MMX) is a robotic space probe set for launch in 2026 to bring back the first samples from Mars' largest moon Phobos. Developed by the Japan Aerospace Exploration Agency (JAXA) and announced on 9 June 2015, MMX will land and collect samples from Phobos once or twice, along with conducting Deimos flyby observations and monitoring Mars's climate.
Commercial Lunar Payload Services (CLPS) is a NASA program to hire companies to send small robotic landers and rovers to the Moon. Most landing sites are near the lunar south pole where they will scout for lunar resources, test in situ resource utilization (ISRU) concepts, and perform lunar science to support the Artemis lunar program. CLPS is intended to buy end-to-end payload services between Earth and the lunar surface using fixed-price contracts. The program achieved the first landing on the Moon by a commercial company in history with the IM-1 mission in 2024. The program was extended to add support for large payloads starting after 2025.
The Artemis program is a Moon exploration program led by the United States' National Aeronautics and Space Administration (NASA), formally established in 2017 via Space Policy Directive 1. It is intended to reestablish a human presence on the Moon for the first time since the Apollo 17 mission in 1972. The program's stated long-term goal is to establish a permanent base on the Moon to facilitate human missions to Mars.
Artemis IV is a planned mission of the NASA-led Artemis program. The mission will include the fourth use of a Space Launch System (SLS) launch vehicle, will send an Orion spacecraft with four astronauts to the Lunar Gateway space station, install a new module on the Gateway, and conduct the second lunar landing of the Artemis program.
Artemis V is the fifth planned mission of NASA's Artemis program and the first crewed flight of the Blue Moon lander. The mission will launch four astronauts on a Space Launch System rocket and an Orion to the Lunar Gateway and will be the third lunar landing of the Artemis program. In addition, Artemis V will also deliver two new elements to the Gateway Space Station.
The Lunar Polar Exploration Mission (LUPEX), is a planned joint lunar mission by the Indian Space Research Organisation (ISRO) and Japan Aerospace Exploration Agency (JAXA). The mission would send an uncrewed lunar lander and rover to explore the south pole region of the Moon no earlier than 2028. It is envisaged to explore the permanently shadowed regions and to determine the quantity and quality of water on the Moon. JAXA is likely to provide the H3 launch vehicle and the rover, while ISRO would be providing the lander.
The Lunar I-Hab is designed as a habitat module of the Lunar Gateway station, to be built by the European Space Agency (ESA) in collaboration with the Japan Aerospace Exploration Agency, or JAXA. The I-HAB will have a maximum launch mass of 10,000 kg (22,000 lb) and provide a habitable volume of 10 m3 (350 cu ft).
Argonaut or European Large Logistics Lander (EL3) is a class of lunar landers designed by the European Space Agency in partnership with Airbus to deliver payloads to the surface of the Moon. The lander is being designed with a versatile set of uses in mind, including use as a power station, support for a rover, cargo delivery, and infrastructure delivery. It is envisioned to launch on an Ariane 64 launch vehicle. As of July 2024, Argonaut Mission 1 is expected to be launched in 2031.
