"MAVEN has made tremendous discoveries about the Mars upper atmosphere and how it interacts with the sun and the solar wind," said Bruce Jakosky, MAVEN principal investigator from the University of Colorado, Boulder. MAVEN has used measurements of the isotopes in the upper atmosphere (atoms of the same composition but having different mass) to determine how much gas has been lost through time.

One of the most intense Martian dust storms ever observed is being studied by a record number of NASA spacecraft. Here is a countdown of the top 10 discoveries from the mission.
Transforming the inhospitable Martian environment into a place astronauts could explore without life support is not possible without technology well beyond today’s capabilities. MAVEN is studying the entire region from the top of the upper atmosphere all the way down to the lower atmosphere so that the connections between these regions can be understood. June 16, 2017 The two-month campaign began February 11 and ended April 5. This results due to the lack of an intrinsic Martian magnetic field and the occurrence of small regions of magnetized crust that can affect the incoming solar wind on local and regional scales. These measurements suggest that 2/3 or more of the gas has been lost to space.2.

The goal of the mission is to determine the role that loss of atmospheric gas to space played in changing the Martian climate through time. "These are allowing us to understand not just the behavior of the atmosphere today, but how the atmosphere has changed through time.

These aurorae are caused by an influx of particles from the sun ejected by different types of solar storms. A type of Martian aurora first identified by NASA’s MAVEN spacecraft in 2016 is actually the most common form of aurora occurring on the Red Planet, according to new results from the mission.

The goal of the mission is to determine the role that loss of atmospheric gas to space played in changing the Martian climate through time.

MAVEN is studying the entire region from the top of the upper atmosphere all the way down to the lower atmosphere so that the connections between these regions can be understood.MAVEN's principal investigator is based at the University of Colorado's Laboratory for Atmospheric and Space Physics, Boulder. Five years after NASA’s MAVEN spacecraft entered into orbit around Mars, data from the mission has led to the creation of a map of electric current systems in the Martian atmosphere.

The Mars atmosphere has been stripped away by the sun and the "We're excited that MAVEN is continuing its observations," said Gina DiBraccio, MAVEN project scientist from NASA's Goddard Space Flight Center in Greenbelt, Maryland. "It's now observing a second Martian year, and looking at the ways that the seasonal cycles and the solar cycle affect the system.

MAVEN made the first direct observations of a layer of metal ions in the Martian ionosphere, resulting from incoming interplanetary dust hitting the atmosphere. This layer is always present, but was enhanced dramatically by the close passage to Mars of Comet Siding Spring in October 2014.7.

Auroras appear on Earth as ghostly displays of colorful light in the night sky, usually near the poles. “MAVEN has made tremendous discoveries about the Mars upper atmosphere and how it interacts with the sun and the solar wind,” said Bruce Jakosky, MAVEN principal investigator from the University of Colorado Boulder. MAVEN observed the full seasonal variation of hydrogen in the upper atmosphere, confirming that it varies by a factor of 10 throughout the year. Your opinions are important to us. Imaging of the distribution of gaseous nitric oxide and ozone in the atmosphere shows complex behavior that was not expected, indicating that there are dynamical processes of exchange of gas between the lower and upper atmosphere that are not understood at present.9.

Artist's Concept of MAVEN Encountering Plasma Layers at Mars The source of the hydrogen ultimately is water in the lower atmosphere, broken apart into hydrogen and oxygen by sunlight.
