Day has turned to night for NASA’s Opportunity rover on Mars.
A huge dust storm that’s now 14-million square miles wide, covering a full quarter of the red planet, has blotted out the sun above Perseverance Valley, Opportunity’s home.
And there’s a good chance the hardest-working rover on Mars won’t make it through the storm.
If you were standing next to the 5-foot-tall rover and looked up into the sky, you wouldn’t be able to see the sun. Dust would be whipping around as Opportunity sits on the rusty ground, with all but its mission clock turned off, waiting for the storm to end.
