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.”

See the passing of a day on Mars with the Curiosity rover

While many of us are on vacation this week between Christmas and New Year, the Curiosity rover on Mars is getting back to work after taking time off last month. In November, NASA's Mars missions paused for two weeks during an event called the Mars solar conjunction, when the sun is directly between Earth and Mars.

That means that any communications signals passing between the two planets would have to pass close to the harsh solar environment, where they would likely be degraded. To avoid any risk of garbled communications sending dangerous signals to the rovers, NASA stopped sending commands to both its Curiosity and Perseverance rovers until the solar conjunction passed.

NASA stops speaking to its Mars robots, but they haven’t fallen out
NASA's Perserverance Mars rover.

NASA’s Mars robots receive their commands from the mission team at the Jet Propulsion Laboratory in Southern California, but for the next few weeks, communications will fall silent.

This is due to that massive fireball in the sky -- aka the sun -- coming between Earth and Mars. The celestial event is known as solar conjunction and happens every couple of years.

The Curiosity rover reaches a milestone on Mars
Curiosity Rover

NASA's Curiosity rover, which is currently exploring Mars' Gale Crater, recently marked an impressive milestone: 4,000 days on Mars. The rover landed more than a decade ago on August 5, 2012, and since then it has continued to explore the area, collect rock samples, and make its way up the epic slopes of Mount Sharp.

The 4,000 days are measured in mission time, which is calculated in martian days or sols. Due to the differing rates of rotation of Earth and Mars, a day on Mars is slightly longer than a day on Earth, by about 40 minutes. And also, due to the difference distances between Earth and Mars and the sun, a martian year is longer too - at 668 sols, equivalent to 687 Earth days. Those working on Mars rover missions, especially the rover drivers, have to operate on Mars time, so their schedules are out of sync with typical Earth working hours and they generally work on 90-sol shifts to allow them time to readjust to Earth schedules.
