Where is Mercury Now

We bid a fond farewell to the MESSENGER spacecraft on April 30th, 2015

"Our craft set a record for planetary flybys, spent more than four years in orbit about the planet closest to the Sun, and survived both punishing heat and extreme doses of radiation. Among its other achievements, MESSENGER determined Mercury’s surface composition, revealed its geological history, discovered that its internal magnetic field is offset from the planet’s center, taught us about Mercury’s unusual internal structure, followed the chemical inventory of its exosphere with season and time of day, discovered novel aspects of its extraordinarily active magnetosphere, and verified that its polar deposits are dominantly water ice. A resourceful and committed team of engineers, mission operators, scientists, and managers can be extremely proud that the MESSENGER mission has surpassed all expectations and delivered a stunningly long list of discoveries that have changed our views not only of one of Earth’s sibling planets but of the entire inner solar system," said Sean Solomon, MESSENGER’s Principal Investigator.

Media and Public Event: MESSENGER’s Top 10 Science and Engineering Accomplishments

After more than 10 years in operation, the MErcury Surface, Space ENvironment, GEochemistry, and Ranging (MESSENGER) spacecraft will impact the surface of Mercury later this month at a speed of more than 3.91 kilometers per second (8,750 miles per hour), marking the end of operations for the hugely successful Mercury orbiter. At this media and public event, scientists and engineers discussed the mission’s accomplishments, provided the Top 10 scientific discoveries, as well as the technological innovations that grew out of the mission. Watch the full briefing and access supporting materials [HERE].

About the MESSENGER Education and Public Outreach website

In developing this site, educators, scientists, and engineers are working together to bring the exciting science of MESSENGER to everyone. Here you will find a wealth of resources about the planet Mercury and about the MESSENGER mission. If you are a student or teacher make sure you check out the special sections containing educational materials and opportunities.

The MESSENGER Education and Public Outreach Team

The MESSENGER education and public outreach program is conducted by a dedicated team of individuals and organizations with a long track record in space science education in both formal (classroom) and informal (museum and science center) settings. Read about the partner organizations here and meet the team that makes it all happen here.
