Sun temporarily halts communications between NASA and Mars missions –

A Mars solar conjunction occurs every two years when the sun moves between Mars and Earth.

(CNN) — Robotic explorers investigating Mars are presently out of contact with area 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 subsequent 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.

Through the roughly two-week interval, the new, energized fuel regularly spewed by the solar from its outer environment can intrude with the radio indicators that NASA makes use of to speak with its Martian robotic explorers.

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

A deliberate communications drop began Saturday and is in place till November 25. For a few these days, mission controllers count on an entire blackout. Nonetheless, they count on to obtain common well being updates from the assorted spacecraft.

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

The slowdown is a pleasant break for the individuals who dedicate their time to engaged on Mars missions, but it surely doesn’t imply the work fully stops. The robotic fleet will nonetheless function — albeit with out the shut supervision they often 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 a press release. “We’ll nonetheless be capable of hear from them and examine their states of well being over the subsequent few weeks.”

Mars rovers and orbiters on autopilot

The Curiosity rover, which just lately marked 4,000 sols (about 11 Earth years) on the Martian floor, discovered an appropriate parking spot inside its exploration website 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 akin to monitoring adjustments 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 elevate and transfer mud round on the pink planet.

The Ingenuity helicopter, which has largely served because the Perseverance rover’s aerial scout, can even lie low and received’t conduct any flights throughout this time. As an alternative, the chopper will examine the motion of sand utilizing its coloration digicam. Whereas the task feels like a easy job, sand might be one of many largest 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 observe interactions between the solar and the Martian environment.

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