Mars rovers give scientists a ground-level view of the red planet – peek inside their NASA control room

(THE CONVERSATION) Lights blink on as I enter the Rover Operations Center at NASA’s Jet Propulsion Laboratory in Pasadena, California, at 7:30 a.m. I’m the primary to reach, though I already really feel late.

Someday in the course of the evening on Earth, the Curiosity rover completed its day exploring on Mars and beamed its newest assortment of pictures and measurements to a Mars orbiter zooming by overhead. The orbiter relayed the information to Earth, the place it now waits on servers right here and at companion establishments across the globe.

As soon as our rover operations shift kicks off at 8:15 a.m., a number of dozen engineers and scientists may have simply three hours to test the well being of the rover, analyze the brand new science knowledge and agree on the subsequent set of rover actions. Then we’ll spend one other 4 hours turning these plans into rover instructions for tomorrow, ensuring they’re protected and match inside the rover’s accessible time and power. Not lengthy after that, the Solar will rise on Mars, and Curiosity will look towards Earth, anticipating its subsequent directions.

As Curiosity’s project scientist, it’s my job to make sure that what emerges from this rush is a set of measurements that advance the mission’s science aims and hold it on observe to realize what our staff promised NASA and, in the end, the general public. It’s a seemingly overwhelming job given every little thing that should occur within the subsequent seven hours. However after repeating it over a thousand instances since Curiosity landed in 2012, our staff has gotten fairly good at it.

NASA created Curiosity to seek for proof of historic liveable environments, akin to these with liquid water and the chemical substances, vitamins and power sources required for all times. The investigation referred to as for a long-lived, cellular spacecraft that might permit scientists on Earth to just about discover an area space on Mars, choose and purchase rock samples, and analyze them in onboard laboratories.

JPL responded with the car-size, drill-equipped Curiosity rover. NASA added a collection of scientific devices and a science staff from america and world wide.

NASA despatched Curiosity to Mars’ Gale Crater to climb Aeolis Mons, a mountain whose 3 miles (5 kilometers) of sedimentary rock layers maintain a file of environmental circumstances from about 3.5 billion years in the past. The proof means that again then a thicker, historic ambiance sheltered flowing streams and sparkling lakes.

Curiosity has climbed by means of a vertical half-mile (1 kilometer) of rock layers thus far, discovering clay-rich, mudstone layers that give manner at greater elevations to youthful sandstones stuffed with salty minerals. Our staff decided that lakes endured for millions of years earlier than the local weather turned arid and sand dunes overtook the lakes, though groundwater often breached the floor to supply streams that wove among the many dunes.

Samples Curiosity drilled from the lake sediments include small organic – meaning carbon-based – molecules, the raw materials for potential life. The affiliation of moist environments, natural molecules and a mixture of chemical substances related to those who microbes harness for power on Earth allowed our staff to conclude that circumstances in Gale had been as soon as capable of supporting life. Figuring out conclusively whether life actually took hold would require bringing such rocks again to laboratories on Earth.

As my colleagues arrive within the constructing and on-line, I’m misplaced within the newest pictures. Curiosity is effectively into the upper and drier strata of Aeolis Mons, but the rocks have salts, scours and other signs of ancient water. These pictures recommend that even perhaps Mars’ dry interval offered habitats for all times.

Throughout our earlier shift, I requested the engineers who plan the rover’s path to take it into an space that seems exceptionally easy and flat on pictures taken from orbit. After years of rough offroad driving, they had been excited to open up the throttle and let the rover drive 120 toes (37 meters) throughout this Martian “parking zone” – a reasonably lengthy distance for Curiosity.

What I’m now’s taking my breath away. As a substitute of easy slabs, each floor across the rover is textured by small polygons, every a number of inches throughout, as if somebody lined Mars in honeycomb wallpaper. Our geologists suspect that the polygons define fractures that shaped by means of drying, like cracks in mud do, or by means of thermal cycles, or compression.

My pc display exhibits the realm in entrance of Curiosity lined by dots, every one representing a candidate goal for the rover to watch with its cameras, its laser spectrometer, or the sensors on its arm. There are manner too many dots, which isn’t a nasty downside to have. A science staff member educated to reasonable the day’s dialogue begins to slender the checklist. Distinguished school, postdocs and college students from world wide take turns advocating for his or her goal.

The talk facilities on what set of pictures and chemical measurements will finest assist distinguish how the polygons shaped. I’m the tiebreaker if our staff can’t shortly attain consensus, however that’s hardly ever wanted. It’s Friday, so the three days of actions we plan for the rover at the moment will happen over the weekend, and the outcomes will arrive for our subsequent shift on Monday. Curiosity works weekends.

In a while, I stroll into the adjoining room the place a robotics engineer visualizes in 3D how Curiosity’s five-jointed arm will attain the successful rock targets. I sit down subsequent to a different engineer who’s simulating the rover’s subsequent drive. We agree that the terrain forward is tough: no extra parking zone, all curbs. We talk about how she would possibly steer the rover across the rock obstacles to achieve the subsequent science waypoint.

By midday, the science staff’s function in operations is completed, however my colleagues linger on-line to debate the newest knowledge in additional element. In the meantime, the rover and instrument operators start changing the day’s scientific requests into a whole lot of instructions that have to be despatched to NASA’s Deep Space Network in a number of hours. There’s nonetheless lots to do, however the staff is within the homestretch for the day.

On Mars, the horizon is beginning to brighten. Earlier than too lengthy, Curiosity will likely be anticipating to listen to from us.
