Your help would be greatly appreciated by NASA scientists as they attempt to resolve a fundamental mystery about Mars' atmosphere.
Through its citizen science platform Zooniverse, NASA has organized a project that utilizes citizen science. 'Cloudspotting on Mars' allows people to identify clouds on the red planet.
The information could help researchers understand why the atmosphere is only 1% as dense as Earth's, despite evidence that the planet used to have a much thicker atmosphere.
“Marek Slipski, a postdoctoral researcher at NASA's Jet Propulsion Laboratory, said in a press release, 'We want to learn what triggers the formation of clouds, particularly water ice clouds that can reveal how much water vapour is in the atmosphere during different seasons.'
Cloudspotting on Mars can help you do that. Mars Reconnaissance Orbiter (MRO), which has been studying Earth's neighbour since 2006, has 16 years of data. With its Mars Climate Sounder instrument, the orbiter studies the atmosphere in infrared light.
Measurements taken with this instrument show clouds to be in the form of arches. Public participation will allow the team to more efficiently study where clouds occur in the atmosphere by marking the arches.
Humans can spot them much more easily by eye, according to the space agency. The project could also help the scientists create better algorithms that could potentially perform this work in the future. Participants in the project attend periodic webinars where scientists explain how the data will be used.
Mars was probably covered by lakes and rivers billions of years ago, indicating that the atmosphere was thicker back then.
There are several theories as to how it lost its atmosphere over time. A number of mechanisms may be lofting water high into the atmosphere, where solar radiation breaks it into its two component elements, oxygen and hydrogen.
Hydrogen is light, so it would just drift away into space. In addition to having clouds of ice, Mars also has clouds of carbon dioxide, or dry ice. By understanding where and how these clouds appear, scientists hope to gain a better understanding of Mars' middle atmosphere (50 to 80 kilometres above the surface).
