Topic: Dust Storm
Last year, a fleet of NASA spacecraft got a detailed look at the life cycle of the 2018 global dust storm that ended the Opportunity rover’s mission. And while scientists are still puzzling over the data, two papers recently shed new light on a phenomenon observed within the storm: dust towers, or concentrated clouds of dust that warm in sunlight and rise high into the air. ![]() Side-by-side movies shows how the 2018 global dust storm enveloped the Red Planet, courtesy of the Mars Color Imager (MARCI) camera onboard NASA’s Mars Reconnaissance Orbiter (MRO). This global dust storm caused NASA’s Opportunity rover to lose contact with Earth. (NASA/JPL-Caltech/MSSS) «Read the rest of this article» Sections: Technology | No Comments
NASA’s Mars Reconnaissance Orbiter finishes 60,000 trips around Mars
Since entering orbit on March 10th, 2006, the spacecraft has been collecting daily science about the planet’s surface and atmosphere, including detailed views with its High Resolution Imaging Science Experiment camera (HiRISE). HiRISE is powerful enough to see surface features the size of a dining room table from 186 miles (300 kilometers) above the surface. ![]() This still from an animation shows NASA’s Mars Reconnaissance Orbiter soaring over Mars. The spacecraft has been in Mars orbit for 13 years, and just completed 60,000 trips around the planet. (NASA/JPL-Caltech) «Read the rest of this article» Sections: Technology | No Comments
NASA’s Mars InSight Lander to learn from Dust Cleanings
Dust clearings are also expected for Mars’ newest inhabitant, the InSight lander. Because of the spacecraft’s weather sensors, each clearing can provide crucial science data on these events, as well – and the mission already has a glimpse at that. ![]() This is NASA InSight’s second full selfie on Mars. Since taking its first selfie, the lander has removed its heat probe and seismometer from its deck, placing them on the Martian surface; a thin coating of dust now covers the spacecraft as well.

NASA ponders whether Dust Storms responsible for Water Loss on Mars
The global Martian dust storm of summer 2018 — the one that blotted out sunlight for weeks and put NASA’s beloved Opportunity rover out of business — offered an unprecedented learning opportunity. For the first time, humans had eight spacecraft orbiting Mars or roving its surface — the largest cadre of robotic explorers ever to watch a global dust storm unfold. ![]() This is an image of a May 11th, 2016, selfie of NASA’s Curiosity Mars rover at a drilled sample site called “Okoruso.” (NASA/JPL-Caltech/MSSS) «Read the rest of this article» Sections: News | No Comments
Last Photos from NASA’s Opportunity Rover on MarsNASA Jet Propulsion Laboratory
“This final panorama embodies what made our Opportunity rover such a remarkable mission of exploration and discovery,” said Opportunity project manager John Callas of NASA’s Jet Propulsion Laboratory in Pasadena, California. ![]() This image is a cropped version of the last 360-degree panorama taken by the Opportunity rover’s Panoramic Camera (Pancam) from May 13 through June 10, 2018. The view is presented in false color to make some differences between materials easier to see. (NASA/JPL-Caltech/Cornell/ASU) «Read the rest of this article» Sections: Technology | No Comments
Six Things to Know About NASA’s Mars Opportunity RoverNASA Jet Propulsion Laboratory
1. Opportunity was a twin. The Mars Exploration Rovers mission featured two identical, golf-cart-sized, solar-powered rovers: Spirit and Opportunity. Spirit landed at Gusev Crater on January 4th, 2004. Opportunity landed on the opposite side of Mars at Meridiani Planum on January 24th, 2004 PST (January 25th EST). Both rovers were managed for NASA by NASA’s Jet Propulsion Laboratory in Pasadena, California. ![]() his infographic highlights NASA’s twin robot geologists, the Mars Exploration Rovers (MER) Spirit and Opportunity.

NASA’s Opportunity Mars Rover Mission EndsNASA Headquarters
The Opportunity rover stopped communicating with Earth when a severe Mars-wide dust storm blanketed its location in June 2018. After more than a thousand commands to restore contact, engineers in the Space Flight Operations Facility at NASA’s Jet Propulsion Laboratory (JPL) made their last attempt to revive Opportunity Tuesday, to no avail. The solar-powered rover’s final communication was received June 10th. ![]() The dramatic image of NASA’s Mars Exploration Rover Opportunity’s shadow was taken on sol 180 (July 26, 2004), by the rover’s front hazard-avoidance camera as the rover moved farther into Endurance Crater in the Meridiani Planum region of Mars.

NASA’s Opportunity Rover has been on Mars for 15 YearsNASA Jet Propulsion Laboratory
The golf-cart-sized rover was designed to travel 1,100 yards (1,006 meters) and operate on the Red Planet for 90 Martian days (sols). It has traveled over 28 miles (45 kilometers) and logged its 5,000th Martian day (or sol) back in February of 2018. ![]() An artist’s concept portrays the NASA Mars Opportunity Rover on the surface of Mars.

NASA lists Five Things you should know about InSight’s Mars LandingNASA’s Jet Propulsion Laboratory
On November 26th, 2018 NASA will try to safely set a new spacecraft on Mars. InSight is a lander dedicated to studying the deep interior of the planet – the first mission ever to do so. ![]() This is an illustration showing a simulated view of NASA’s InSight lander about to land on the surface of Mars. This view shows the underside of the spacecraft. (NASA/JPL-Caltech) «Read the rest of this article» Sections: Technology | No Comments
NASA explains How a Tiny Curiosity Motor Identified a Massive Martian Dust StormWritten by Lonnie Shekhtman
NASA’s Mars Reconnaissance Orbiter (MRO) provided the earliest insights on May 30th when it observed an accumulation of dust in the atmosphere near Perseverance Valley, where NASA’s Opportunity rover is exploring. ![]() Globes from May 28th and July 1st show a global dust storm completely obscuring the surface of Mars.
