Two images from a Mast Camera (Mastcam) on NASA’s Curiosity corsair depicting windy changes given a informal Mars dirt charge widespread to turn tellurian and descended in aspiring on Curiosity’s plcae in Gale Crater. The left picture shows a Duluth cavalcade site on May 21, 2018 (Sol 2058); a right picture is a same site on Jun 17 (Sol 2084). Both images have been white offset and contrast-enhanced. The pink in a right picture is due to Mars’ dust. Image around NASA/JPL-Caltech/MSSS.

It’s cold and comforting when inlet does what we expect. And – most as a seasons on Earth change in a unchanging approach – so anniversary dirt storms are a underline of Mars’ circuit around a sun, occurring around a time a universe is closest to a object (Mars’ perihelion, or closest point, comes about each dual Earth-years and will come this year on Sep 16). Sometimes a dirt storms sojourn regional, though not so with a charge seen to be distracted on Mars given early June. Now a charge of little dirt particles has engulfed most of Mars and is strictly planet-encircling or global. NASA’s Opportunity corsair had to postpone scholarship operations early in a storm. Its solar panels contingency by now be blanketed with dust, and indeed – as of a latest NASA refurbish on Opportunity – there is still no vigilance perceived from a rover. Across a planet, NASA’s Curiosity corsair – that has been investigate Martian dirt during Gale Crater – is approaching to sojourn mostly unblushing by a dirt given it runs on a nuclear-powered battery. Especially now that a charge has widespread over Curiosity’s location, this corsair is in a good position to investigate a ongoing Mars dirt charge from a ground. NASA said on Jun 20:

Dust has usually increasing over Curiosity’s location, some-more than doubling over a weekend. The sunlight-blocking haze, called tau, is now above 8.0 during Gale Crater — a top tau a goal has ever recorded. Tau was final totalled nearby 11 over Opportunity, thick adequate that accurate measurements are no longer probable for Mars’ oldest active rover.

For NASA’s tellurian scientists examination from a ground, Curiosity offers an rare window to answer some questions. One of a biggest is: because do some Martian dirt storms final for months and grow massive, while others stay tiny and final usually a week?

Scott D. Guzewich, an windy scientist during NASA Goddard Space Flight Center in Greenbelt, Maryland, is streamer Curiosity’s dirt charge investigation. He pronounced of a doubt above:

We don’t have any good idea.

Curiosity is now a usually active corsair on Mars’ surface, though differently a swift of booster – both NASA qualification and from other countries – are in circuit around Mars. I’ve counted 8 sum stream missions during Mars during Wikipedia’s list of missions to Mars page, with a ninth mission, Insight Mars, launched as recently as May 5 and streamer for a Nov 2018 alighting on Mars.

With all these conceivable robots orbiting Mars, or creeping opposite a surface, NASA forked out that this will be a initial time we’ve been means to collect:

… a resources of dirt information both from a aspect and from space. The final charge of tellurian bulk that enveloped Mars was in 2007, 5 years before Curiosity landed there.

Stay tuned! There’s expected to be some-more about a Mars dirt charge ahead.

A self-portrait taken by NASA’s Curiosity corsair taken on Jun 15, 2018 (Sol 2082). A Martian dirt charge has reduced object and prominence during a rover’s plcae in Gale Crater. In this image, Curiosity is confronting a void rim, about 18.6 miles (30 kilometers) divided from where it stands inside a crater. Daily photos prisoner by a Mast Camera, or Mastcam, uncover a sky removing hazier. This sun-obstructing wall of mist isabout 6 to 8 times thicker than normal for this time of season. Image around NASA/JPL-Caltech.

Bottom line: The dirt charge distracted on Mars has now strictly turn planet-encircling or global. The Curiosity corsair – now a usually active corsair on Mars’ aspect – is investigate a Martian dust, that has widespread to a location. Across a planet, a solar-powered Opportunity corsair has left silent. Look for updates on Opportunity here.
