Mars' moons: Phobos and Deimos orbiter
 

Phobos And Deimos & Mars Environment (PADME) is a low-cost NASA Mars orbiter mission concept that would address longstanding unknowns about Mars' two moons Phobos and Deimos and their environment. [1] [2] [3] [4] [5]

Contents

The PADME mission competed for Discovery Program funding, but lost to the Psyche and Lucy missions. [3] [4] [5] [6] The Principal Investigator is Anthony Colaprete. Other principals include Pascal Lee (Deputy Principal Investigator) and Butler Hine (Project Manager). [1] [5]

Objectives

The origin of Mars' moons, which were discovered by astronomer Asaph Hall, remains unknown. PADME would advance the scientific understanding of the origin of Phobos and Deimos by studying: [3] [5]

In addition, PADME would assess potential resources (water, organics, regolith) and potential hazards (dust) that Phobos and Deimos might present for future human exploration in Mars orbit. [3] [4] [5]

Mission

Once in Mars orbit, PADME would carry out 16 flybys of Phobos followed by 9 flybys of Deimos. [5] Flybys would take place at two-week intervals. Flyby altitudes at closest approach to Phobos and Deimos would be ~2 km. [5] Following completion of its primary mission, PADME could remain in high Mars orbit for long-term monitoring of the martian system and search for potential additional moonlets around Mars. Alternatively, PADME could be made to escape Mars and eventually fly by a Near-Earth Object (NEO). [5]

NASA Ames Research Center would design, develop, build, and test the PADME spacecraft, and manage mission operations. [1] [3] [4] [5] The proposal is to employ the proven Modular Common Spacecraft Bus (MCSB), previously used by the LADEE Moon orbiter. [1] [5] Major partners include the SETI Institute, Jet Propulsion Laboratory, NASA Goddard Space Flight Center, and University of Colorado's Laboratory for Atmospheric and Space Physics. [3] [4] [5]

Scientific payload

The PADME mission has four science instruments plus a radio science experiment which uses the spacecraft's radio communications system. [5]

The orbiter could also carry an optional laser communications experiment. [5]

Proposed launch

PADME could launch on a Medium-lift class launch vehicle. The spacecraft would fit within all Atlas V, Delta IV, and Falcon 9 launch vehicle fairings. If selected, PADME would have been launched in August 2020 and reached Mars seven months later, by March 2021. [5]

International participation

PADME includes the participation of scientists from Belgium, France, Italy, and Japan. [3] [4] [5]

The Mariner program was conducted by the American space agency NASA to explore other planets. Between 1962 and late 1973, NASA's Jet Propulsion Laboratory (JPL) designed and built 10 robotic interplanetary probes named Mariner to explore the inner Solar System - visiting the planets Venus, Mars and Mercury for the first time, and returning to Venus and Mars for additional close observations.

Phobos is the innermost and larger of the two natural satellites of Mars, the other being Deimos. The two moons were discovered in 1877 by American astronomer Asaph Hall. It is named after Phobos, the Greek god of fear and panic, who is the son of Ares (Mars) and twin brother of Deimos.

<span class="mw-page-title-main">Deimos (moon)</span> Smallest and outer moon of Mars

Deimos is the smaller and outer of the two natural satellites of Mars, the other being Phobos. Deimos has a mean radius of 6.2 km (3.9 mi) and takes 30.3 hours to orbit Mars. Deimos is 23,460 km (14,580 mi) from Mars, much farther than Mars's other moon, Phobos. It is named after Deimos, the Ancient Greek god and personification of dread and terror.

<span class="mw-page-title-main">Exploration of Mars</span> Overview of the exploration of Mars

The planet Mars has been explored remotely by spacecraft. Probes sent from Earth, beginning in the late 20th century, have yielded a large increase in knowledge about the Martian system, focused primarily on understanding its geology and habitability potential. Engineering interplanetary journeys is complicated and the exploration of Mars has experienced a high failure rate, especially the early attempts. Roughly sixty percent of all spacecraft destined for Mars failed before completing their missions, with some failing before their observations could even begin. Some missions have been met with unexpected success, such as the twin Mars Exploration Rovers, Spirit and Opportunity, which operated for years beyond their specification.

<i>Nozomi</i> (spacecraft) Failed Mars orbiter

Nozomi was a Japanese Mars orbiter that failed to reach Mars due to electrical failure. It was constructed by the Institute of Space and Astronautical Science, University of Tokyo and launched on July 4, 1998, at 03:12 JST with an on-orbit dry mass of 258 kg and 282 kg of propellant. The Nozomi mission was terminated on December 31, 2003.

The Discovery Program is a series of Solar System exploration missions funded by the U.S. National Aeronautics and Space Administration (NASA) through its Planetary Missions Program Office. The cost of each mission is capped at a lower level than missions from NASA's New Frontiers or Flagship Programs. As a result, Discovery missions tend to be more focused on a specific scientific goal rather than serving a general purpose.

The two moons of Mars are Phobos and Deimos. They are irregular in shape.

The Lunar Atmosphere and Dust Environment Explorer was a NASA lunar exploration and technology demonstration mission. It was launched on a Minotaur V rocket from the Mid-Atlantic Regional Spaceport on September 7, 2013. During its seven-month mission, LADEE orbited the Moon's equator, using its instruments to study the lunar exosphere and dust in the Moon's vicinity. Instruments included a dust detector, neutral mass spectrometer, and ultraviolet-visible spectrometer, as well as a technology demonstration consisting of a laser communications terminal. The mission ended on April 18, 2014, when the spacecraft's controllers intentionally crashed LADEE into the far side of the Moon, which, later, was determined to be near the eastern rim of Sundman V crater.

The Modular Common Spacecraft Bus (MCSB) is a fast-development, low-cost, general purpose spacecraft platform. Its modular design is intended to reduce the cost, complexity, and lead time on missions by providing a reliable, well-characterized system that can carry a variety of payloads. According to NASA, "the spacecraft is roughly one tenth the price of a conventional uncrewed mission and could be used to land on the Moon, orbit Earth, or rendezvous with near-Earth objects."
