Lights blink on as I enter the Rover Operations Heart at NASA’s Jet Propulsion Laboratory in Pasadena, California, at 7:30 a.m. I’m the primary to reach, regardless that I already really feel late.
Someday throughout the night time on Earth, the Curiosity rover completed its day exploring on Mars and beamed its newest assortment of photos and measurements to a Mars orbiter zooming by overhead. The orbiter relayed the info to Earth, the place it now waits on servers right here and at associate 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 examine 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 secure and match throughout the rover’s obtainable time and vitality. Not lengthy after that, the Solar will rise on Mars, and Curiosity will look towards Earth, anticipating its subsequent directions.
As Curiosity’s undertaking 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 attain what our staff promised NASA and, finally, the general public. It’s a seemingly overwhelming activity given the whole lot 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 Curiosity undertaking scientist Ashwin Vasavada guides this tour of the rover’s view of the Martian floor. NASA created Curiosity to seek for proof of historic liveable environments, similar to these with liquid water and the chemical substances, vitamins and vitality sources required for all times. The investigation known as for a long-lived, cell spacecraft that may 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 the US and around the globe.
NASA despatched Curiosity to Mars’ Gale Crater to climb Aeolis Mons, a mountain whose 3 miles (5 kilometers) of sedimentary rock layers maintain a report of environmental situations from about 3.5 billion years in the past. The proof means that again then a thicker, historic environment sheltered flowing streams and glowing lakes.
Curiosity has climbed by way of a vertical half-mile (1 kilometer) of rock layers to this point, discovering clay-rich, mudstone layers that give approach at greater elevations to youthful sandstones stuffed with salty minerals. Our staff decided that lakes persevered for thousands and thousands of years earlier than the local weather grew to become 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 natural – which means carbon-based – molecules, the uncooked supplies for potential life. The affiliation of moist environments, natural molecules and a mixture of chemical substances comparable to people who microbes harness for vitality on Earth allowed our staff to conclude that situations in Gale had been as soon as able to supporting life. Figuring out conclusively whether or not life truly took maintain 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 photos. Curiosity is effectively into the upper and drier strata of Aeolis Mons, but the rocks have salts, scours and different indicators of historic water. These photos recommend that maybe even 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 clean and flat on photos taken from orbit. After years of tough offroad driving, they had been excited to open up the throttle and let the rover drive 120 ft (37 meters) throughout this Martian “parking zone” – a reasonably lengthy distance for Curiosity.
