Solar conjunction halts communications between Mars missions and NASA


NASA’s Perseverance rover captured this view of the situation the place it will likely be parked throughout Mars photo voltaic conjunction.

Robotic explorers investigating Mars are presently out of contact with house companies on Earth after hitting an enormous communications roadblock.

Mission controllers at NASA received’t ship any instructions to its fleet of orbiters and rovers, together with Perseverance and Curiosity, for the following 10 days because of the Mars photo voltaic conjunction.

The phenomenon happens each two years when Mars and Earth are unfavorably positioned on reverse sides of the solar as they journey alongside their particular person orbits.

Throughout the roughly two-week interval, the new, energized gasoline frequently spewed by the solar from its outer ambiance can intervene with the radio indicators that NASA makes use of to speak with its Martian robotic explorers.


A Mars photo voltaic conjunction happens each two years when the solar strikes between Mars and Earth.

If engineers try to ship instructions to any of the Martian spacecraft throughout this time, the messages could get combined up — and that gamble isn’t well worth the danger of rovers or orbiters receiving corrupted communication that would endanger them.

A deliberate communications drop began Saturday and is in place till November 25. For a few these days, mission controllers anticipate a whole blackout. Nevertheless, they anticipate to obtain common well being updates from the varied spacecraft.

The slowdown is a pleasant break for the individuals who dedicate their time to engaged on Mars missions, nevertheless it doesn’t imply the work utterly stops. The robotic fleet will nonetheless function — albeit with out the shut supervision they normally obtain.

“Our mission groups have spent months making ready to-do lists for all our Mars spacecraft,” mentioned Roy Gladden, supervisor of the Mars Relay Community at NASA’s Jet Propulsion Laboratory in Pasadena, California, in an announcement. “We’ll nonetheless be capable to hear from them and test their states of well being over the following few weeks.”

Mars rovers and orbiters on autopilot

The Curiosity rover, which lately marked 4,000 sols (about 11 Earth years) on the Martian floor, discovered an appropriate parking spot inside its exploration web site of Gale Crater. About 2,300 miles (3,700 kilometers) away, Perseverance additionally settled right into a spot in Jezero Crater.

Each rovers acquired the prolonged lists of instructions previous to the communications blackout that may maintain them busy, together with duties resembling monitoring modifications within the Martian climate, floor circumstances and radiation.

Perseverance will take the chance to survey surrounding rocks and use its cameras to identify clouds and dirt devils. Weaker and smaller than tornadoes on Earth, mud devils are swirling vortices of air that raise and transfer mud round on the pink planet.

The Ingenuity helicopter, which has largely served because the Perseverance rover’s aerial scout, may also lie low and received’t conduct any flights throughout this time. As an alternative, the chopper will examine the motion of sand utilizing its shade digital camera. Whereas the task appears like a easy job, sand might be one of many greatest and most difficult obstacles to Mars missions.

In the meantime from above, the Mars Reconnaissance and Odyssey orbiters will proceed taking photos of the pink planet’s floor, whereas MAVEN (brief for Mars Atmospheric and Unstable Evolution) will monitor interactions between the solar and the Martian ambiance.

As soon as the conjunction interval is over, the robotic fleet will share the collected information, and the Mars missions and their groups will resume their regular cadence of exploring the pink planet.
