NASA’s Martian Fleet is low with the sun between Earth and the Red Planet

“Although our missions to Mars are not as active in the next few weeks, they will still let us know their state of health,” said Roy Gladden, head of the Mars Relay Network at NASA’s Jet Propulsion Laboratory in Southern California. “Each mission was given homework to do until they heard from us again.”

Here’s how some of those Mars missions will spend that time:

  • Perseverance will take meteorological measurements with its MEDA (short for Mars Environmental Dynamics Analyzer) sensors, will search for dust devils with its cameras (although it will not move its mast, or “head”), will run its RIMFAX (Radar Imager for Mars’ Subsurface Experiment) and capture new sounds with its microphones.
  • The Ingenuity Mars helicopter will remain stationary at its location 575 feet (175 meters) from Perseverance and communicate its status weekly to the rover.
  • The Curiosity rover will perform meteorological measurements using its REMS (Rover Environmental Monitoring Station) sensors, perform radiation measurements with its RAD (Radiation Assessment Detector) and DAN (Dynamic Albedo of Neutrons) sensors, and search for devils of dust with its suite of cameras.
  • The InSight stationary lander will continue to use its seismometer to detect tremors like the large earthquakes it recently captured.
  • NASA’s three orbiters – Odyssey, Mars Reconnaissance Orbiter and MAVEN – will all continue to relay some data from the agency’s surface missions to Earth, in addition to gathering their own science.

While a limited amount of scientific data will reach Earth during the conjunction, the spacecraft will retain most of it until after the moratorium. (This means there will be a temporary pause in the flow of raw images available from Perseverance, Curiosity, and InSight.)

Then, they’ll transmit their remaining data to NASA’s Deep Space Network, a massive Earth-based radio antenna system run by JPL. Engineers will spend about a week downloading the information before normal spacecraft operations resume. If the teams monitoring these missions determine that any of the scientific data collected has been corrupted, they can usually have that data retransmitted.
