description MAVEN Overview
MAVEN, short for Mars Atmosphere and Volatile Evolution, is a NASA orbiter launched in 2013 and placed into orbit around Mars in 2014. It studies the planet's upper atmosphere, ionosphere, and interaction with the solar wind using instruments that measure particles, fields, and atmospheric composition. Its observations help scientists investigate how atmospheric gas escaped to space and how Mars changed from a wetter ancient environment into the colder, drier planet observed today.

help MAVEN FAQ
What does the MAVEN spacecraft stand for?
MAVEN stands for Mars Atmosphere and Volatile Evolution, a NASA orbiter launched in 2013. It was placed into orbit around Mars in 2014 to study the planet's upper atmosphere, ionosphere, and interactions with the solar wind.
What is the main scientific objective of the MAVEN mission?
The primary goal of MAVEN is to determine how Mars lost its early atmosphere and liquid water over billions of years. By measuring the current rate at which atmospheric gases escape to space, scientists hope to understand the planet's climate history.
How does NASA's MAVEN communicate with Earth?
MAVEN is equipped with a high-gain antenna that allows it to act as a crucial data-relay station for other missions on the Martian surface. It has successfully transmitted data back to Earth from rovers like Curiosity and Perseverance.
When did MAVEN arrive at Mars?
The spacecraft was successfully launched from Earth in November 2013. It then traveled through space for ten months before officially inserting itself into Mars' elliptical orbit in September 2014.
