A NASA spacecraft on Mars is headed for a dusty demise.
The Insight lander is losing power because of all the dust on its solar panels. NASA said Tuesday it will keep using the spacecraft's seismometer to register marsquakes until the power peters out, likely in July. Then flight controllers will monitor InSight until the end of this year, before calling everything off.
Since landing on Mars in 2018, InSight has detected more than 1,300 marsquakes; the biggest one, a magnitude 5, occurred two weeks ago. NASA's two other functioning spacecraft on the Martian surface -- rovers Curiosity and Perseverance -- are still going strong thanks to nuclear power. The space agency may rethink solar power in the future for Mars, said planetary science director Lori Glaze, or at least experiment with new panel-clearing tech or aim for the less-stormy seasons.
The InSight team anticipated this much dust buildup, but hoped a gust wind of wind or dust devil might clean off the solar panels. That has yet to happen, despite several thousand whirlwinds coming close.
