Resource Prospector is a cancelled mission concept by NASA of a rover that would have performed a survey expedition on a polar region of the Moon. The rover was to attempt to detect and map the location of volatiles such as hydrogen, oxygen and lunar water which could foster more affordable and sustainable human exploration to the Moon, Mars, and other Solar System bodies. [2] [3]
The mission concept was still in its pre-formulation stage, [2] when it was scrapped in April 2018. [4] [5] The Resource Prospector mission was proposed to be launched in 2022. [4] [5] Its science instruments will be flown on several commercial lander missions contracted with NASA's new Commercial Lunar Payload Services program. The VIPER rover is developed as a successor of Resource Prospector.
In February 1976, the Soviet lander Luna 24 sent a sample of lunar soil to Earth, where it was found to contain about 0.1% water. [6] [7] Data obtained by the Lunar Reconnaissance Orbiter (LRO), Chandrayaan-1, and the Lunar Crater Observation and Sensing Satellite (LCROSS), revealed that lunar water is distributed widely (if thinly) across the Moon's surface. [3] [8]
The Resource Prospector mission concept proposes a NASA-led collaboration that seeks international space agencies and private industry partners to maximize the value. [2] However, it is unclear if the use of lunar resources is permitted under the 1967 Outer Space Treaty signed by the United States, Russia, and 90 other countries. [9]
Hydrogen and oxygen can be used to make vital consumables, but also, to make rocket fuel, and basic materials required for in-space manufacturing. [2] The technical process is called in situ resource utilization or ISRU. The rover would have used a drill to extract samples of the lunar soil from as deep as one meter below the surface. [2] The Taiwanese National Chung-Shan Institute of Science and Technology was responsible for developing the rover's sensor system. [10]
In September 2015, the rover prototype underwent field testing, [11] and in May 2016, the prototype rover underwent thermal vacuum and thermal testing at NASA's Johnson Space Center in Houston, Texas. [12] [9] Before its cancellation, NASA officials were exploring various launch options, including to fly it as a secondary payload on board the second flight of the Space Launch System, called the Artemis 2 in 2022. [9] Another reported launch option was the Falcon Heavy rocket. [9]
The Resource Prospector team was notified on 23 April 2018 to cease all work on the project by the end of May 2018. The concept was going to be submitted for a major design review by the end of 2018 for funding, development and launch. [4] [5] This rover was the only mission in conceptual development by NASA to explore the surface of the Moon in situ. [4] Apparently, the cancellation stemmed from the program being moved to another Division with an insufficient budget to fund this mission. [13] [4] US$100 million were already spent on the rover's instruments over ten years. [14] Scientists involved in the Lunar Exploration Analysis Group sent a letter on 26 April 2018 to the NASA administrator, James Bridenstine laying their case to reverse the decision, [13] and remarked that other nations are preparing landers to stake claim on the natural resources on the south polar region of the Moon. [13]
In a 3 May 2018 statement, NASA officials explained that lunar surface exploration will continue in the future, but using commercial lander services under a new Commercial Lunar Payload Services (CLPS) program. [15] [16] Some of these commercial landers will be equipped with the ice drill and scientific instruments developed for the Resource Prospector. [14] [16] NASA officials stated that under this program, Resource Prospector instruments will go forward in an expanded lunar surface campaign, instead of the original two weeks. [17]
Preliminary studies call for a rover of about 300 kg (660 lb), that would measure 1.4 m x 1.4 m x 2 m. [1] It was suggested to be launched with a Falcon 9 rocket. [1] The mission life would have been between 6 and 14 Earth days. [1]
The motivation and purpose of the mission was to characterize the nature and distribution of lunar water and other volatiles in lunar polar sub-surface materials, and to demonstrate in situ resource utilization (ISRU) processing of lunar soil by heating samples in an oven and isolating the resulting volatiles. [1]
The conceptual payload includes: [9] [1] [18]
The drill, NSS and NIRVSS spectrometers will be launched in 2022 on board the VIPER rover.
Lunar water is water that is present on the Moon. Diffuse water molecules in low concentrations can persist at the Moon's sunlit surface, as discovered by the SOFIA observatory in 2020. Gradually, water vapor is decomposed by sunlight, leaving hydrogen and oxygen lost to outer space. Scientists have found water ice in the cold, permanently shadowed craters at the Moon's poles. Water molecules are also present in the extremely thin lunar atmosphere.
In space exploration, in situ resource utilization (ISRU) is the practice of collection, processing, storing and use of materials found or manufactured on other astronomical objects that replace materials that would otherwise be brought from Earth.
NASA proposed several concept moonbases for achieving a permanent presence of humans on the Moon since the late 1950s. Research and exploration of the Moon has been a large focus of the organization since the Apollo program. NASA's peak budget was in 1964-1965, when it comprised 4% of all federal spending in service of the Apollo Moon landing project. Though lunar landings ever since the conclusion of the Apollo program in 1972 have ceased, interest in establishing a permanent habitation on the lunar surface or beyond low Earth orbit has remained steady. Recently, renewed interest in lunar landing has led to increased funding and project planning. NASA requested an increase in the 2020 budget of $1.6 billion, in order to make another crewed mission to the Moon under the Artemis program by 2025, followed by a sustained presence on the Moon by 2028. A crew was selected for the planned crewed mission, Artemis II, in April 2023.
Astrobotic Technology inc., commonly referred to as Astrobotic is an American private company that is developing space robotics technology for lunar and planetary missions. It was founded in 2007 by Carnegie Mellon professor Red Whittaker and his associates with the goal of winning the Google Lunar X Prize. The company is based in Pittsburgh, Pennsylvania. Their first launch occurred on January 8, 2024, as part of NASA's Commercial Lunar Payload Services (CLPS) program. The launch carried the company's Peregrine lunar lander on board the first flight of the Vulcan Centaur rocket from Florida's Space Force Station LC-41. The mission was unable to reach the Moon for a soft or hard landing. On June 11, 2020, Astrobotic received a second contract for the CLPS program. NASA will pay Astrobotic US$199.5 million to take the VIPER rover to the Moon, targeting a landing in November 2024.
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.
Lunar Flashlight was a low-cost CubeSat lunar orbiter mission to explore, locate, and estimate size and composition of water ice deposits on the Moon for future exploitation by robots or humans.
Lunar IceCube is a NASA nanosatellite orbiter mission that was intended to prospect, locate, and estimate amount and composition of water ice deposits on the Moon for future exploitation. It was launched as a secondary payload mission on Artemis 1, the first flight of the Space Launch System (SLS), on 16 November 2022. As of February 2023 it is unknown whether NASA team has contact with satellite or not.
Luna 27 is a planned lunar lander mission by the Roscosmos with collaboration by the European Space Agency (ESA) to send a lander to the South Pole–Aitken basin, an area on the far side of the Moon. Its objective will be to detect and characterise lunar polar volatiles. The mission is a continuation of the Luna-Glob programme.
Artemis 3 is planned to be the first crewed Moon landing mission of the Artemis program and the first crewed flight of the Starship HLS lander. Artemis 3 is planned to be the second crewed Artemis mission and the first American crewed lunar landing since Apollo 17 in December 1972. In December 2023, the Government Accountability Office reported that the mission is not likely to occur before 2027; as of January 2024, NASA officially expects Artemis 3 to launch no earlier than September 2026 due to issues with the valves in Orion's life support system.
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 was extended to add support for large payloads starting after 2025.
ispace Inc. is a public Japanese company developing robotic spacecraft and other technology to compete for both transportation and exploration mission contracts from space agencies and other private industries. ispace's mission is to enable its clients to discover, map, and use natural lunar resources.
The Intuitive Machines Nova-C, or simply Nova-C, is a class of lunar landers designed by Intuitive Machines (IM) to deliver small payloads to the surface of the Moon. Intuitive Machines was one of three service providers awarded task orders in 2019 for delivery of NASA science payloads to the Moon. The IM-1 lunar lander, named Odysseus, was launched by a SpaceX Falcon 9 rocket on 15 February 2024, reached lunar orbit on 21 February, and landed on the lunar surface on 22 February. This marked the inaugural Nova-C landing on the Moon and the first American spacecraft to perform a soft landing on the Moon in over 50 years. It is the first spacecraft to use methalox propulsion to navigate between the Earth and the Moon.
McCandless Lunar Lander, also known as the McCandless Lunar Delivery Service, is a concept for a robotic lunar lander proposed as one of the commercial cargo vehicles for NASA's Commercial Lunar Payload Services (CLPS). The lander was proposed to NASA for funding by the aerospace company Lockheed Martin, and it is based on the successful Mars landers Phoenix and InSight.
The Artemis program is a Moon exploration program that is led by the United States' NASA and was formally established in 2017 via Space Policy Directive 1. The Artemis program is intended to reestablish a human presence on the Moon for the first time since Apollo 17 in 1972. The program's stated long-term goal is to establish a permanent base on the Moon to facilitate human missions to Mars.
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 2026. It is envisaged to explore the permanently shadowed regions on the Moon. JAXA is likely to provide the H3 launch vehicle and the rover, while ISRO would be providing the lander.
The Moon bears substantial natural resources which could be exploited in the future. Potential lunar resources may encompass processable materials such as volatiles and minerals, along with geologic structures such as lava tubes that, together, might enable lunar habitation. The use of resources on the Moon may provide a means of reducing the cost and risk of lunar exploration and beyond.
VIPER is a lunar rover developed by NASA, and currently planned to be delivered to the surface of the Moon in November 2024. The rover will be tasked with prospecting for lunar resources in permanently shadowed areas in the lunar south pole region, especially by mapping the distribution and concentration of water ice. The mission builds on a previous NASA rover concept called Resource Prospector, which was cancelled in 2018.
Polar Resources Ice Mining Experiment-1 (PRIME-1) is a robotic NASA experiment that is designed to search for water ice on the Moon at a permanently shadowed location near Shackleton Crater, close to the lunar south pole. PRIME-1 is scheduled for launch on a Falcon 9 in late 2024 as part of the Commercial Lunar Payload Services (CLPS) program on the Nova-C IM-2 mission.
Lunar Trailblazer is a planned small lunar orbiter, part of NASA's SIMPLEx program, that will detect and map water on the lunar surface to determine how its form, abundance, and location relate to geology. Its mission is to aid in the understanding of lunar water and the Moon's water cycle. Lunar Trailblazer is currently slated to launch in 2024 as a secondary payload on the IM-2 mission. The Principal Investigator (PI) of the mission is Bethany Ehlmann, a professor at Caltech.
