Official documents, followed by an announcement from NASA, show that the space agency will expand 8 of its planetary missions due to "their productivity and their scientific potential to deepen our knowledge and understanding of the solar system and beyond" according to them.

NASA's green wave missions to expand are Mars Odyssey, Mars Reconnaissance Orbiter, MAVEN, Mars Science Laboratory (Curiosity Rover), InSight lander, Lunar Reconnaissance Orbiter, OSIRIS-REx, and New Horizons.

In an announcement, the US space agency NASA says it has decided to extend most missions by 3 years.

However, there are exceptions.

For example, OSIRIS-REx missions will continue for the next 9 years and InSight will only continue until the end of this year, but it is not a final decision.

NASA plans to further expand the InSight mission to Mars if the spacecraft's electric power allows for longer operations.

The proposal to extend these missions was approved by 50 reviewers with two coordinating independent presidents overseeing the process.

In the end, it was decided that 8 NASA planetary missions (mentioned above) have the potential to bring more scientific data, can work, and will be able to answer more questions about the solar system.

These extensions to the 8 planetary missions will not only mean less money spent and more scientific data but also important programmatic benefits for NASA, some of these missions promise multidivisional scientific benefits across NASA's Scientific Mission Direction (SMD).

These extensions are welcomed by scientists.

In addition, the extra years that these missions will have will help us better understand the planet Mars, which will have an effect on NASA's initiatives for future missions.

"Extended missions provide us with the opportunity to leverage NASA's large investments in exploration, allowing continued science operations at a cost far lower than developing a new mission," said Lori Glaze, director of the Planetary Science Division at NASA Headquarters in Washington. "Maximizing taxpayer dollars in this way allows missions to obtain valuable new science data, and in some cases, allows NASA to explore new targets with totally new science goals."

What do scientists say about each mission?

  • OSIRIS-APEX (Principal Investigator: Dr. Daniella DellaGiustina, University of Arizona): The Origins, Spectral Interpretation, Resource Identification, Security-Regolith Explorer (OSIRIS-REx) mission is currently on its way back to Earth to deliver the samples of asteroid Bennu that it collected in 2020. Dante Lauretta, OSIRIS-REx PI, will remain in place for the primary mission, while DellaGiustina begins her role as the newly named PI for OSIRIS-APophis EXplorer (OSIRIS-APEX). With a new name to reflect the extended mission's new goals, the OSIRIS-APEX team will redirect the spacecraft to encounter Apophis, an asteroid roughly 1,200 feet (roughly 370 meters) in diameter that will come within 20,000 miles (32,000 kilometers) of Earth in 2029. OSIRIS-APEX will enter orbit around Apophis soon after the asteroid's Earth flyby, providing an unprecedented close-up look at this S-type asteroid. It 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.
  • MAVEN (Principal Investigator: Dr. Shannon Curry, University of California, Berkeley): The Mars Atmosphere and Volatile Evolution (MAVEN) mission 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.
  • InSight (Principal Investigator: Dr. Bruce Banerdt, JPL): Since landing on Mars in 2018, the Interior Exploration using Seismic Investigations, Geodesy and Heat Transport (InSight) mission has operated the only active seismic station beyond Earth. Its seismic monitoring of "marsquakes" has provided constraints on Mars' interior, formation, and current activity. The extended mission will continue InSight's seismic and weather monitoring if the spacecraft remains healthy. However, 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.
  • Lunar Reconnaissance Orbiter (LRO) (Project Scientist: Dr. Noah Petro, GSFC): 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 Regions (PSRs) near the poles where water ice may be found. LRO will also provide important programmatic support for NASA's efforts to return to the Moon.
  • Mars Science Laboratory (MSL) (Project Scientist: Dr. Ashwin Vasavada, JPL): The Mars Science Laboratory and its Curiosity rover have driven more than 16 miles (27 km) on the surface of Mars, exploring the history of habitability in Gale Crater. In its fourth extended mission, MSL will climb to higher elevations, exploring the critical sulfate-bearing layers that give unique insights into the history of water on Mars.
  • New Horizons (Principal Investigator: Dr. Alan Stern, SwRI): New Horizons flew past Pluto in 2015 and the Kuiper Belt object (KBO) Arrokoth in 2019. In its second extended mission, New Horizons will continue to explore the distant solar system out to 63 astronomical units (AU) from Earth. The New Horizons spacecraft can potentially conduct multidisciplinary observations of relevance to the solar system and NASA's Heliophysics and Astrophysics divisions. Additional details regarding New Horizons' science plan will be provided at a later date.
  • Mars Odyssey (Project Scientist: Dr. Jeffrey Plaut, JPL): 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. The Odyssey orbiter also continues to provide unique support for real-time data relay from other Mars spacecraft. The length of Odyssey's extended mission may be limited by the amount of propellant remaining aboard the spacecraft.
  • Mars Reconnaissance Orbiter (MRO) (Project Scientist: Dr. Rich Zurek, JPL): MRO has provided a wealth of data regarding the processes on Mars' surface. In its sixth extended mission, MRO will study the evolution of Mars' surface, ices, active geology, and atmosphere and climate. In addition, MRO will continue to provide important data relay service to other Mars missions. MRO's CRISM instrument will be shut down entirely, after the loss of its cryocooler has ended the use of one of its two spectrometers.
