On April 30, 2015, after more than ten years in space – four of those in orbit – MESSENGER‘s mission and operational life came to its conclusive (and expected) end when it impacted the surface of Mercury. While the spacecraft’s approximate impact location was predicted by mission engineers (it was out of sight of Earth at the time)…

Goodbye, MESSENGER. You May Be Gone But You Won’t Be Forgotten!
At 3:34 p.m. EDT (19:34 UTC) today, April 30, 2015, after more than ten years in space – and four of them in orbit – the MESSENGER spacecraft’s operational life came to a conclusive end when it impacted the surface of Mercury, as planned. After revealing the surface of the innermost planet like no mission ever…
An Oblique View of Abedin Is One of MESSENGER’s Final Scenes
The 72-mile (116-km) -wide crater Adedin is seen at an oblique angle in this mosaic made from images acquired by NASA’s MESSENGER spacecraft. The angle highlights the crater’s central peak complex which surrounds a shallow depression that could have a volcanic origin, as well as fine cracks in the floor of its basin and a…
MESSENGER Gets Up Close and Personal With Mercury
Mercury’s ready for its close-up, Mr. MESSENGER! At an incredible 5 meters per pixel, the image above is one of the highest-resolution images of Mercury’s surface ever captured. It was acquired on March 15 with the MESSENGER spacecraft’s MDIS (Mercury Dual Imaging System) instrument and shows an 8.3-km (5.2-mile) -wide section of the planet’s north polar region, speckled…
MESSENGER Gets It “Donne”
Named after the 17th-century English metaphysical poet, Mercury’s Donne crater was captured in this image by NASA’s MESSENGER spacecraft. The 53-mile (83-km) -wide crater features a large, rounded central peak and numerous lobate scarps lining its floor. What are lobate scarps? Find out more here.
Success! Mercury has a new satellite named MESSENGER!
During a week of not-so-great news in the world (to understate things by quite a lot) it’s nice to report something good: the MESSENGER spacecraft has successfully established orbit around the planet Mercury, beginning its new 12-month mission of mapping and researching the innermost planet of our solar system! After traveling nearly 5 billion miles…
MESSENGER’s Day in the Sun
After 7 years and almost 5 billion of miles of traveling around the blistering inner solar system NASA’s MESSENGER spacecraft is finally ready for the moment it was created for: orbital insertion around Mercury, the innermost planet! At 9pm EDT tomorrow MESSENGER will attempt to establish orbit and if successful will become the first spacecraft…
NASA Announces Two New Exploration Missions
Happy New Year! Just four days into 2017 NASA announced its pick for two new Discovery missions to explore our solar system: one to investigate a few of the “Trojan” asteroids that Jupiter has gathered into its orbit with its mighty gravity, and another to visit the remains of an ancient planet’s metallic core! “These are true…

Pencil This In: Mercury’s Surface is Darkened by Graphite
Monochromatic and covered in craters, Mercury may outwardly resemble our Moon but the similarities abruptly end there. Ever since the MESSENGER spacecraft entered orbit around Mercury in 2011, and indeed even since Mariner 10‘s flyby in 1974, peculiar “dark spots” observed on the planet’s surface have intrigued scientists as to their composition and origin. Now, thanks to high-resolution spectral…

And if you love space, these are the ones you’ll want. Produced by Starry Messenger Press in conjunction with The Planetary Society, the 2016 Year in Space calendar…
Here’s Your Chance to Name a Crater on Mercury!
On March 18, 2011, MESSENGER became the first human-made spacecraft to enter orbit around Mercury. Now almost four years, eight billion miles, and over 260,000 images later, MESSENGER is nearing the end of its operational life. To commemorate the many achievements of the mission, scientists from NASA and the MESSENGER teams at the Johns Hopkins…
