Perseverance rover begins trek to seek life on Mars

With the fiery flash of a rocket launch, NASA’s Perseverance rover headed out today for what’s expected to be a decade-long campaign to store up and bring back Martian samples that may hold evidence of alien life.

United Launch Alliance’s Atlas 5 rocket lifted off from Cape Canaveral Air Force Station in Florida at 7:50 a.m. ET (4:50 a.m. PT), sending the rover into space for a seven-month cruise to Mars.

Due to the COVID-19 pandemic, access to the area surrounding the launch pad was restricted, but hundreds of thousands of people watched the liftoff via streaming video. And as if the pandemic wasn’t enough of a challenge, in the minutes before launch, a magnitude-4.2 earthquake rattled through NASA’s Jet Propulsion Laboratory in Pasadena, Calif., where the rover mission is managed.

Mission managers said the complications had no effect on the countdown.

“This is all about perseverance,” NASA Administrator Jim Bridenstine said during the buildup to liftoff. “Going to Mars is all about persevering in general. Doing it now is more persevering than ever before.”

Mars mission puts working from home to the ultimate test

The launch of NASA’s Mars Perseverance rover marks the start of a seven-month-long journey involving tens of millions of miles of travel — but it also marks the end of an eight-year-long journey involving millions of miles of travel on the part of scientists and engineers across the country.

And perhaps the biggest marvel is that, in the end, most of them got the rover and its scientific instruments ready for launch while working from home.

Working from home has been a tough thing to manage for many of the businesses affected by the coronavirus pandemic and social-distancing restrictions. It’s been tough for NASA as well.

“Putting a spacecraft together that’s going to Mars, and not making a mistake — it’s hard, no matter what. Trying to do it during the middle of a pandemic, it’s a lot harder,” Matt Wallace, the mission’s deputy project manager at NASA’s Jet Propulsion Laboratory in Pasadena, Calif., said during a pre-launch briefing.

Fortunately, NASA and its partners could draw upon decades’ worth of experience in remote operations. “When the pandemic came along, it didn’t make that much difference in the way I operate, because I was already used to working remotely with JPL,” said the University of Washington’s Tim Elam, who’s part of the science team for the rover’s X-ray fluorescence spectrometer.

Once the rover is on its way, working remotely will become even more routine. “Pasadena is about the same distance away from Mars that Seattle is,” Elam joked.

It’s the summer of Mars: Check your Red Planet IQ

It’s been more than two years since the most recent launch to Mars, but traffic to the Red Planet is due to pick up dramatically in the next couple of weeks.

The United Arab Emirates could start things off as soon as Sunday (July 19) with the launch of its first-ever interplanetary probe, the Hope orbiter. Liftoff from Japan’s Tanegashima Space Center is set for as early as 5:58 p.m. ET (1:58 a.m. UAE time July 20), with a Japanese H-2A rocket providing the ride.

The UAE is an up-and-comer in the space business, as evidenced by last year’s first space mission by an Emirati astronaut. This Mars mission celebrates the Emirates’ 50th anniversary as a nation, and is being carried out by the Mohammed bin Rashid Space Centre in collaboration with a variety of U.S. research institutions.

The car-sized Hope orbiter is designed to provide a weather-satellite style view of the Martian atmosphere over the course of its two-year-long primary mission. Hope’s launch has been delayed a couple of times due to unfavorable weather in Japan, but once liftoff takes place, it should be clear sailing to orbital insertion at Mars next February.

China is next up with its Tianwen-1 orbiter, lander and rover. The spacecraft should be sent on its way from the Wenchang Spacecraft Launch Site atop a Long March 5 rocket sometime next week.

Assuming all goes as advertised, Tianwen-1’s landing platform will touch down on a Martian plain known as Utopia Planitia next February. The rover will roll off the platform, take pictures, analyze rock samples and use a radar instrument to hunt for pockets of subsurface water.

Meanwhile, the orbiter will be snapping high-resolution pictures from above and serving as a communications relay. Tianwen (which means “Questioning the Heavens”) is China’s first Mars mission and could lay the groundwork for a sample return mission in the late 2020s.

NASA is also preparing for a sample return mission. On July 30, it’s due to launch the Mars Perseverance rover from Cape Canaveral Air Force Station in Florida atop a United Launch Alliance Atlas 5 rocket.

Perseverance takes advantage of the same basic chassis design and plutonium-powered batteries used for the Curiosity rover, which is still in operation eight years after landing on Mars. But its instruments are optimized to look for the chemical signs of ancient microbial life.

After the one-ton, SUV-sized rover makes its February touchdown in Jezero Crater, one of its primary tasks will be to collect promising samples of Martian rock and soil for eventual return to Earth. Perseverance is also packing a mini-helicopter called Ingenuity, which could become the first powered aircraft to fly on another planet.

There’s a reason why all these spacecraft are due for takeoff this summer, heading for a landing next February. Because of the orbital relationship between Earth and Mars, the optimal opportunity for a trip to the Red Planet comes every 26 months.

NASA’s Mars InSight lander took advantage of the 2018 opportunity, and now it’s time once again for Mars-bound missions to lift off — or wait for the next turn in 2022.

There’ll be a lot more on the Red Planet menu in the next few weeks, and this Mars IQ test should serve as an appetizer. Are you a space cadet or a Mars commander? If you’ve read this story, you should get at least the first quiz question right…

Mars rover carries monument to COVID-19 medics

When NASA’s Perseverance rover lands in Mars’ Jezero Crater next February, it’ll be carrying a tribute to the medical community and their work to quell the coronavirus pandemic.

A 3-by-5-inch aluminum plaque, showing planet Earth being supported by the ancient staff-and-serpent symbol of the medical profession, will grace the left side of the rover chassis.

Matt Wallace, the mission’s deputy project manager at NASA’s Jet Propulsion Laboratory, said the plaque recognizes the sacrifices that have been made by medical workers — and also by members of the mission team, who had to go to extraordinary lengths to keep the $2.4 billion project on track for launch as early as July 20.
