- 3561 - SPACE - ongoing missions in 2022? - Eight interplanetary spacecraft have a go to continue their missions at Mars, the moon, and asteroids. These eight science missions hold substantial potential to continue bringing new discoveries.
--------------------- 3561 - SPACE - ongoing missions in 2022?
-
---------------- 1) MARS - Curiosity rover, the Mars Science Laboratory (MSL), landed on Mars in 2012 and will explore for another three years. It has spent several years climbing Mount Sharp (Aeolis Mons) after landing on the Red Planet's Gale Crater. It is on a long-term hunt to understand how water, and potential conditions for life, arose in that region of the planet.
-
- MSL will climb to higher elevations, exploring the critical sulfate-bearing layers which give unique insights into the history of water on Mars.
-
---------------- 2) MOON -Lunar Reconnaissance Orbiter (LRO) has been in operation since 2009, and will work for another three years. It is best-known for mapping surface detail of the moon in high-definition, tracking down landing missions (or crashes) past and present, and seeking preserves of ice water on the moon.
-
- NASA will be using its data in planning for its Artemis moon-landing program that plans boots on the surface no earlier than 2025. LRO will continue to study the surface and geology of the moon.
-
- The evolution of LRO's orbit will allow it to study new regions away from the poles in unprecedented detail, including the permanently shadowed craters near the poles where water ice may be found.
-
---------------------- 3) ASTEROID - The Origins, Spectral Interpretation, Resource Identification, Security-Regolith Explorer (OSIRIS-REx) mission will have another stop after dropping off pieces of asteroid Bennu at Earth in 2023.
-
- The spacecraft, in flight since 2016, will be redirected to visit Apophis, a near-Earth asteroid that was once deemed a slight threat to Earth in 2068.
-
- The asteroid will safely come within 20,000 miles of Earth in 2029. NASA plans to study changes in the asteroid caused by its close flyby of Earth, and use the spacecraft’s gas thrusters to attempt to dislodge and study the dust and small rocks on and below Apophis’ surface.
-
- OSIRIS-Rex will pivot to analyzing samples from Bennu after their return.
-
----------------------- 4) The Mars Atmosphere and Volatile EvolutioN mission (MAVEN) launched in November 2013 to look at changes in the atmosphere of the Red Planet. It is suspected that gradual erosion of the atmosphere over the eons led to less running water at the surface of Mars, when pressure dropped.
-
- The extended mission over another three years plans to study the interaction between Mars' atmosphere and magnetic field during the upcoming solar maximum. MAVEN's observations as the sun's activity level increases toward the maximum of its 11-year cycle will deepen our understanding of how Mars' upper atmosphere and magnetic field interact with the sun.
-
---------------------- 5) MARS - InSight Mars landed on Mars in 2018 and has been useful in getting information on "marsquakes" to learn more about the planet's interior and how that evolved over the eons.
-
- The spacecraft has been working well, aside from the failure of a below-surface probe known as a "mole" and gradual dust buildup on its solar panels. Given its shaky power status, the mission has a few more months tacked on its mission until the end of 2022.
-
- The extended mission will continue InSight's seismic and weather monitoring if the spacecraft remains healthy. Due to dust accumulation on its solar panels, InSight's electrical power production is low, and the mission is unlikely to continue operations for the duration of its current extended mission unless its solar panels are cleared by a passing 'dust devil' in Mars’ atmosphere.
-
---------------- 6) KUIPER BELT - New Horizons in the Kuiper Belt launched in 2006 and has visited two worlds so far: dwarf planet Pluto in 2015, and the Kuiper Belt object Arrokoth (2014 MU69) in 2019. The mission is expected to fly as far as 63 astronomical units in its next three years.
-
- The New Horizons spacecraft can potentially conduct multi-disciplinary observations of relevance to the solar system, and NASA's heliophysics and astrophysics divisions.
-
---------------------- 7) MARS - The Mars Odyssey spacecraft started work in 2001 and continues to work well in its third decade in space. While NASA warned the mission is running low on propellant, it hopes to squeeze another three years from the mission. Besides being a remote scientist, Odyssey serves as a relay for other Mars spacecraft on the surface in sending their communications back to Earth.
-
- Mars Odyssey's extended mission will perform new thermal studies of rocks and ice below Mars’ surface, monitor the radiation environment, and continue its long-running climate monitoring campaign.
-
----------------- 8) MARS - Mars Reconnaissance Orbiter has been in service since 2005 and provides a long-term view of the surface of the Red Planet. It charts changes in sand dunes, ice caps and other features and also keeps an eye on missions on the Red Planet.
-
- Aside from the loss of one instrument (the Compact Reconnaissance Imaging Spectrometer for Mars, or CRISM) due to a loss of coolant that shut down one of the two spectrometers, the mission should operate for another three years. MRO will continue its relay services for surface missions, too.
-
- MRO will study the evolution of Mars’ surface, ices, active geology, and atmosphere and climate. It will continue to provide important data relay service to other Mars missions.
