A NASA Mars orbiter has been busy since it arrived at the Red Planet late last month.

NASA’s Mars Atmosphere and Volatile EvolutioN mission (MAVEN for short) is designed to probe Mars’ thin atmosphere, to help scientists understand what caused the planet to change from a warm, wet world long ago to the cold and dry one it is today. The spacecraft entered into orbit around Mars on Sept. 21, and it has already beamed back some amazing new data about Mars’ upper atmosphere, researchers said.

In MAVEN’s first few weeks of instrument testing at the Red Planet, scientists have already created some of the most complete maps of atomic hydrogen, oxygen, carbon and ozone in the Martian atmosphere ever made. One of MAVEN’s instruments even collected data as energetic particles blasted out by a massive solar eruption made it to Mars.

MAVEN is still in the “commissioning phase” of its mission, meaning that the probe hasn’t started collecting science full-time. The new data were gathered as the spacecraft’s ground controllers began turning on its instruments after it arrived at Mars.

“What we’re seeing so far is really just a tantalizing teaser of what’s to come,” MAVEN principal investigator Bruce Jakosky, of the Laboratory for Atmospheric and Space Physics at the University of Colorado, Boulder, said during a NASA news conference today.

Scientists working with MAVEN weren’t able to see exactly how the solar energetic particles (SEPs) affected Mars’ atmosphere on Sept. 29 because the instruments necessary for that kind of observation weren’t functioning in tandem at that time. MAVEN researchers expect, however, that the spacecraft’s instruments will be ready to observe the atmosphere during the next Mars-directed solar event.

“After traveling through interplanetary space, these energetic particles of mostly protons deposit their energy in the upper atmosphere of Mars,” SEP instrument lead Davin Larson, of the University of California, Berkeley’s Space Sciences Laboratory, said in a statement. “An SEP event like this typically occurs every couple weeks. Once all the instruments are turned on, we expect to also be able to track the response of the upper atmosphere to them.”

Scientists think that solar weather events could be partially responsible for the loss of the Martian atmosphere over time.

Ground controllers are now moving MAVEN into its lower, science orbit in order to take more observations of the planet’s upper atmosphere and find out how some of it might be escaping into outer space. The probe should begin its primary science mission in about two weeks, NASA officials said.

The $671 million MAVEN mission is also gearing up to watch a comet make a close flyby of the Red Planet on Oct. 19.

Comet Siding Spring is set to give Mars a close shave when it flies 87,000 miles (140,000 kilometers) by the planet. NASA’s fleet of spacecraft on and around Mars are planning to make observations of the comet’s flyby. MAVEN should be able to see how the comet’s flyby might affect the Martian atmosphere, researchers have said.

About Earth Changes Media w/ Mitch Battros

Mitch Battros is a scientific journalist who is highly respected in both the scientific and spiritual communities due to his unique ability to bridge the gap between modern science and ancient text. Founded in 1995 – Earth Changes TV was born with Battros as its creator and chief editor for his syndicated television show. In 2003, he switched to a weekly radio show as Earth Changes Media. ECM quickly found its way in becoming a top source for news and discoveries in the scientific fields of astrophysics, space weather, earth science, and ancient text. Seeing the need to venture beyond the Sun-Earth connection, in 2016 Battros advanced his studies which incorporates our galaxy Milky Way - and its seemingly rhythmic cycles directly connected to our Solar System, Sun, and Earth driven by the source of charged particles such as galactic cosmic rays, gamma rays, and solar rays. Now, "Science Of Cycles" is the vehicle which brings the latest cutting-edge discoveries confirming his published Equation.
