It was only in the early 1960s that NASAвЂ™s Mariner missions fully disproved LowellвЂ™s theories.This guide will walk you through setting up News Rover to work with UseNetServer news servers. American astronomer Percival Lowell, working in the late 1890s, popularized the idea that there were signs of Martian canals on the surface. Rice said that for decades, many people believed there was life on Mars. вЂњI describe it as being constantly jet-lagged for three months,вЂќ she said. In 2012, when the Curiosity rover landed, she was one of a team of scientists at the Jet Propulsion Laboratory in Pasadena, Calif., who kept their work schedules correlated with the Mars orbiter, so that they could be ready to pore over the data as soon as it arrived. at Cornell in 2012, where her thesis examined signs of water at the Gusev and Eberswalde craters on Mars.

In graduate school at Cornell, she was trained on how to work with some of the earlier Mars rovers. Rice, who went to high school at Forest Ridge School of the Sacred Heart in Bellevue, first became interested in Mars while majoring in astrophysics at Wellesley College in Massachusetts.

Layers of rocks are expected to offer hints as to why its climate changed so dramatically. The rover is now at the base of Mount Sharp, and scientists believe the mountain contains clues to 3 billion years of MarsвЂ™ history. All of the data needed to guide the decision on the landing is available on NASAвЂ™s website, she said. Next quarter, sheвЂ™s going to put her students to work on an assignment to pick out a prospective landing site for the 2020 rover - work that Mars scientists will actually be doing next year. вЂњThe only way you have that certainty is to repeat the experiment multiple times.вЂќ вЂњIf we found some bio-signature, the implications would be so profound, we would want to be absolutely sure it wasnвЂ™t an instrument calibration,вЂќ she said.

Rice said scientists must perform experiments on Martian rocks in an earthbound lab so they can be repeated and verified.

That rover will collect samples of rocks and store them on the planet, so that a subsequent mission can retrieve them and return them to Earth. The next rover, planned for 2020, will try to answer whether there are signs of life on Mars, Rice said. ThatвЂ™s how scientists deduce the mineral composition of the rocks the rover encounters. A big part of RiceвЂ™s graduate work was searching in databases for spectral patterns of Earth rocks, and matching those patterns to the rocks found on Mars. The roverвЂ™s photographs show rock colors both visible and invisible to the human eye. The rover team spends much of its time comparing photos of Mars to similar-looking geological formations on Earth to try to deduce what happened on the planetвЂ™s surface. вЂњWeвЂ™ve found really compelling evidence that the roverвЂ™s landing site on Mars not only had water, but water that was not too salty, not too acidic, and that had the kinds of nutrients that might have been able to sustain life,вЂќ she said. And Rice says the evidence is strong that Mars once had an environment more like EarthвЂ™s - moist and warm, with an atmosphere that was robust enough to sustain liquid water at the surface. Rather, the rover was designed to explore whether parts of Mars could have been habitable at some point. вЂњBut a door that we thought had been closed actually is not.вЂќД¬uriosity isnвЂ™t designed to detect life on Mars, and if it found some remnants of ancient life, scientists might not even recognize it as such, Rice said. вЂњItвЂ™s definitely not evidence for life on Mars and it doesnвЂ™t necessarily make it more likely that there is,вЂќ Rice said.
