As of today (Feb. 4, 2016) the MAVEN spacecraft has been in orbit around Mars for 500 days!

MAVEN’s orbit gives it the most comprehensive view of the Martian atmosphere to date. Circling the red planet every 4.5 hours on an elliptical path, MAVEN passes close to the north and south poles at an inclination of 75 degrees. This allows MAVEN to gather a north-south swath of data with each pass. At the same time, Mars itself rotates eastward beneath MAVEN, giving the orbiter longitudinal coverage. The combination of MAVEN’s orbit and Mars’ daily rotation provides a complete picture of the Martian atmosphere every day.

Cgi bullshit. Why don't you guys provide original video for the #nasatards?

Ancient regions on Mars bear signs of abundant water—such as features resembling valleys and deltas, and minerals that only form in the presence of liquid water. Scientists think that billions of years ago, the atmosphere of Mars was much denser and warm enough to form rivers, lakes, and perhaps even oceans of water. As the planet cooled and lost its global magnetic field, the solar wind and solar storms eroded away to space a significant amount of the planet’s atmosphere, turning Mars into the cold, arid desert we see today.

The goal of MAVEN is to determine how much of Mars’ atmosphere and water have been lost to space, and how these processes have changed the climate on the Red Planet over its history.

Mars vs Earth facts

‪#‎MAVEN‬ is the first mission devoted to understanding the ‪#‎Martian‬ upper atmosphere. In its first year of science operations, MAVEN identified the process that appears to have played a key role in the transition of the Martian climate from an early, warm, and wet environment that might have supported surface life to the cold, arid planet Mars is today.

MAVEN measurements indicate that the solar wind strips away gas at a rate of about 100 grams (equivalent to roughly 1/4 pound) every second and that atmospheric erosion increases significantly during solar storms.

Did you know that ‪#‎Mars‬' atmosphere is 100 times less dense than Earth's and that it is composed of 96% CO₂ and 2% Argon?

NASA will provide details of key science findings from the agency’s ongoing exploration of ‪#‎Mars‬ during a news briefing at 2 p.m. EST on Thursday, Nov. 5 in the James Webb Auditorium at NASA Headquarters in Washington.

The event will be broadcast live on NASA Television and the agency's website: http://www.nasa.gov/nasatv.

The news conference participants will be:
-- Michael Meyer, lead scientist for the Mars Exploration Program at NASA Headquarters
-- Bruce Jakosky, ‪#‎MAVEN‬ principal investigator at the Laboratory for Atmospheric and Space Physics (LASP) at the University of Colorado Boulder 
-- Jasper Halekas, MAVEN Solar Wind Ion Analyzer instrument lead at the University of Iowa 
-- Yaxue Dong, MAVEN science team member at LASP 
-- Dave Brain, MAVEN co-investigator at LASP

A brief question-and-answer session will take place during the event with media on site and by phone. Members of the public also can ask questions during the briefing on social media using ‪#‎askNASA‬.

MAVEN data have enabled researchers to determine the rate at which the #Martian atmosphere currently is losing gas to space via stripping by the solar wind. The findings reveal that the erosion of #Mars’ atmosphere increases significantly during solar storms. 

MAVEN measurements indicate that the solar wind strips away gas at a rate of about 100 grams (equivalent to roughly 1/4 pound) every second. Atmospheric erosion increases significantly during solar storms, so #MAVEN scientists have concluded that the loss rate was much higher billions of years ago when the sun was young and more active.

This is terrible for us wishing to study and learn BUT it is also beautiful because we can learn from it

Today, Mars is a global desert with an atmosphere far too thin to support bodies of flowing water, but evidence shows that Mars was considerably wetter in the ancient past. Scientists think that climate change on Mars was caused by the loss of an early, thick atmosphere, and MAVEN is investigating whether it was driven into space.

One of the prime suspects is the solar wind, a stream of electrically charged particles continuously blowing outward from the Sun. Unlike Earth, Mars lacks a global magnetic field to deflect the incoming solar wind. Instead, charged particles from the Sun crash into the Mars upper atmosphere, and can accelerate Martian ions into space. Now, for the first time, MAVEN has observed this process in action–by measuring the velocity of ions escaping from Mars.

This animation compares simulations of ion escape with MAVEN’s observations of oxygen ion flux. The results closely fit the expected pattern, with the most energetic ions (in red) accelerated in a plume above ‪#‎Mars‬, while the majority of escaping ions (green) are lost along the “tail” region in the wake of the solar wind. ‪#‎MAVEN‬’s observations confirm that the solar wind is a significant contributor to atmosphere loss on Mars, and they bring scientists closer to solving the mystery of the ancient Martian climate.

MAVEN Navigation Update

As the ‪#‎MAVEN‬ spacecraft orbits ‪#‎Mars‬, its elliptical orbit precesses and incurs changes over time. In order for scientists to acquire the data they need from Mars' upper atmosphere, the spacecraft must remain within a specific corridor around Mars. The team regularly monitors and models MAVEN's orbit to ensure that targeted densities are maintained throughout the mission

The MAVEN navigation team performs Orbit Trim Maneuvers (OTMs) about once every two weeks in order to maintain the targeted atmospheric density corridor.

The last OTM, performed on Dec. 29 (on orbit number 2429), lowered the periapsis altitude by 11.3 km to near 139 km, where the density of Mars’ atmosphere is 0.17 kg/km³. The orbit period for MAVEN is currently 4 hours 31.2 minutes with an Earth to MAVEN distance of 1.69 A.U.

A solar storm approaches Mars in this artist’s concept. The Red Planet is thought to have lost much of its atmosphere to such extreme space weather.

Story
Tagline
The Mars Atmosphere and Volatile EvolutioN (MAVEN) mission is the first mission devoted to understanding the Martian upper atmosphere. The goal of MAVEN is to determine the role that loss of atmospheric gas to space played in changing the Martian climate through time. Where did the atmosphere – and the water – go?
Introduction
The Mars Atmosphere and Volatile EvolutioN Mission (MAVEN) launched on Nov. 18, 2013 and entered Mars orbit on Sept. 21, 2014 to begin exploring the planet’s upper atmosphere, ionosphere and interactions with the sun and solar wind.
Bragging rights
The second in NASA's Mars Scout missions, MAVEN will determine how much of the Martian atmosphere has been lost over time by measuring the current rate of escape to space and gathering enough information about the relevant processes to allow extrapolation backward in time.
