It’s been known for a while that NASA’s InSight Lander was coming to the top of its operations on Mars after 4 years of service. And it looks as if its final communication with Earth has just taken place.
The flexibility of the lander to take care of power has been impacted by a gradual build-up of dust on the lander’s two 7-feet-wide solar panels.
In a tweet tinged with sadness, InSight’s Twitter account this week posted what’s more likely to be its last image from the red planet before the robot finally shuts down.
“My power’s really low, so this will be the last image I can send,” InSight said within the tweet. “Don’t worry about me though: my time here has been each productive and serene. If I can keep talking to my mission team, I’ll — but I’ll be signing off here soon. Thanks for staying with me.”

In one other tweet shared at the top of November, InSight said: “I’ve been lucky enough to live to tell the tale two planets. 4 years ago, I arrived safely at the second, to the delight of my family back on the primary. Due to my team for sending me on this journey of discovery. Hope I’ve done you proud.”
NASA said on Wednesday that it should officially declare the mission over when InSight misses two consecutive communication sessions with the spacecraft orbiting Mars — a part of the Mars Relay Network — as long as the explanation for the missed communication is the lander itself. After that, the space agency said its Deep Space Network will keep listening out for some time, “just in case.”
InSight launched from Vandenberg Air Force Base in California on May 5, 2018, reaching Mars six months afterward November 26.
Unlike other Mars rovers corresponding to Perseverance and Curiosity, InSight has no wheels and so stayed in the identical spot on at Elysium Planitia for the whole thing of its mission.

NASA said that unlike the missions still being undertaken by the rovers, InSight’s science activities were designed to be “more like a marathon than a sprint.”
The space agency added how over the past 4 years, “the lander data has yielded details about Mars’ interior layers, its liquid core, the surprisingly variable remnants beneath the surface of its mostly extinct magnetic field, weather on this a part of Mars, and numerous quake activity.”
Bruce Banerdt, principal investigator of the InSight mission, said earlier this yr that certainly one of the robot’s legacies is that it “really proves the strategy of seismology for planetary science,” adding: “We’ve been in a position to map out the inside Mars for the primary time in history.”
