NASA is operating its Mars Curiosity rover from workers’ home offices

The coronavirus pandemic has led millions of people around the world to swap their regular office for a home-based alternative.

NASA, for example, last month instructed all of its employees nationwide to work from home in an effort to protect them against the virus and also to help slow its spread.

So how is it working out for, say, the team tasked with operating the Mars Curiosity rover? You’d think it’d need access to all of its advanced equipment to operate a vehicle currently more than 120 million miles from Earth, but, with some careful preparation, the job is getting done.

In an interesting piece on its website, NASA has shed some light on how its Curiosity rover team has been working over the last few weeks, sharing details on how it carried out a particular task using the distant rover.

Usually based at NASA’s Jet Propulsion Laboratory in Southern California, the team is currently dispersed, with each member working from home. NASA said that a recent task involving the rover drilling a rock sample marked the first time the vehicle’s operations had been planned and executed by a team working entirely off-site.

Most of the computer kit could be set up at home, but some parts — for example the high-tech goggles that help the team to work out where to drive Curiosity — had to be left at the base as they need extra computing power to operate. The workaround? 3D glasses. “Although not as immersive or comfortable as the goggles, they work just as well for planning drives and arm movements,” NASA said.

Programming each sequence of actions for Curiosity usually involves as many as 20 people at the Jet Propulsion Laboratory, developing and testing commands while chatting with dozens of others located elsewhere.

“We’re usually all in one room, sharing screens, images, and data,” said Alicia Allbaugh, who leads the team. “People are talking in small groups and to each other from across the room.” But now, working remotely, they’re doing the same job by holding several video conferences at the same time while also using messaging apps to communicate. Science operations team chief Carrie Bridge says she can find herself monitoring as many as 15 chat channels at once.

The system works well, though a day’s planning tends to take one or two hours more than it normally would. NASA said that while the extra time for planning can reduce how many commands it sends to the rover each day, Curiosity is pretty much as scientifically productive as ever.

The team took a while to get used to working together remotely, but Bridge said she always knew everyone would pull together to make it happen.

“It’s classic, textbook NASA,” she said. “We’re presented with a problem and we figure out how to make things work. Mars isn’t standing still for us; we’re still exploring.”

How will NASA keep Mars astronauts safe from cosmic radiation? Here’s the plan
AstroRad Vest

The Artemis I mission, which recently completed a historic test flight around the moon, didn't have any astronauts on board -- but it did have two very special passengers: Helga and Zohar, a pair of highly anatomically detailed dummy torsos, one of which wore a special radiation shielding vest for the journey. Their mission? Measure radiation exposure in deep space and determine whether a vest can help protect astronauts from the unseen dangers of space.

Mars Express orbiter has relayed data from seven different Mars missions
An artist's impression of Mars Express. The spacecraft left Earth for Mars on 2 June 2003. It reached its destination after a six-month journey, and has been investigating the planet since early 2004.

When a rover is exploring the surface of Mars, it doesn't send data straight back to Earth. That's for two reasons: Firstly, it would require a large, powerful antenna which would be cumbersome and expensive to add, and secondly, because of the rotations of Earth and Mars any location on the surface would be pointing in the wrong direction some of the time.

So, to get data back from Mars surface missions, we use a network of Mars orbiters, which collect data from rovers and landers and relay it back to Earth. Known as the Mars Relay Network, these orbiting spacecraft take on relay duties in addition to their scientific roles observing the red planet. Recently, one of these orbiters, the European Space Agency (ESA)'s Mars Express set a new record for relaying data from seven different Mars surface missions.

Curiosity rover investigates salty region of Mars for clues of life
NASA's Curiosity Mars rover used its Mast Camera, or Mastcam, to capture this panorama of a hill nicknamed Bolívar and adjacent sand ridges on Aug. 23, the 3,572nd Martian day, or sol, of the mission.

When it comes to hunting for evidence of ancient life on Mars, some key features that scientists want to explore are areas with high levels of sulfate minerals. These salts form in the presence of water, so even though Mars is dry today, finding these minerals now indicates that there was once water in the region. And areas of water are places where life is most likely to have developed. So it's an exciting time when a Mars rover reaches an area high in sulfates, and the Curiosity rover recently arrived at one such location on Mount Sharp in the Gale Crater.

The sulfates had been identified from orbit by the Mars Reconnaissance Orbiter years ago as a key target for Curiosity to explore, and the rover has already identified a variety of rock types and salt minerals in the area including magnesium sulfate, calcium sulfate, and sodium chloride or table salt.
