The scientists, members of the Mars Upper Atmosphere
Network (Muan, held a meeting in Nicosia this week during which they discussed international co-operation for future exploration missions to Mars.
During Cassini's "Grand Finale" plunge into Saturn's innermost ring and upper atmosphere
in 2017, the mass spectrometer aboard the probe sampled chemicals at altitudes between Saturn's rings and atmosphere.
The signal of the gas, according to a (https://phys.org/news/2018-05-helium-exoplanet-atmosphere.html) release from the University, was so massive that the scientists now believe the upper atmosphere
of WASP-107b could be going up to thousands of kilometers into space.
We should only detect emission from water molecules if the part of the upper atmosphere
they're in is hotter than the gas that lies below--if the gas below were hotter, the water would absorb some of its glow, an effect not seen here.
"The spacecraft and instruments continue to work well, and we're building up a picture of the structure and composition of the upper atmosphere
, of the processes that control its behavior, and of how loss of gas to space occurs," said Bruce Jakosky, MAVEN's principal investigator from the University of Colorado's Laboratory for Atmospheric and Space Physics in Boulder.
Now the real work begins for the $671 million mission, the first dedicated to studying Mars' upper atmosphere
The probe is different from past NASA missions because it focuses not on the dry surface but on the mysteries of the never-before-studied upper atmosphere
. Much of MAVEN's year-long mission will be spent circling the planet 6,000 kilometers (3,800 miles) above the surface.
29 ( ANI ): A NASA spacecraft that is going to explore Mars' upper atmosphere
in unprecedented detail is undergoing final preparations for a scheduled 1:28 p.m.
Prof Aylward first acknowledged that advances in modelling had been the result of efforts by not only himself but also his many co-workers, the subject having begun after World War II when rockets able to probe the upper atmosphere
became available for research.
Summary: The exact whereabouts of the six-tonne Upper Atmosphere
Research Satellite which crashed to Earth on Saturday is still unknown.
