MESSENGER Mission Updates

  • MESSENGER Data from Second Full Mercury Solar Day in Orbit Released by Planetary Data System  →

    09.11.12 - Late last week, the Planetary Data System (PDS) released data collected during MESSENGER's seventh through twelfth month in orbit around Mercury. PDS archives and distributes all of NASA's planetary mission data. With this release, images and measurements are now available to the public for the second full Mercury solar day of MESSENGER orbital operations.

  • MESSENGER Team Mourns the Loss of Neil Armstrong  →

    08.27.12 - The news of Neil Armstrong's death this weekend left many members of the MESSENGER team mourning his loss and reflecting on his legacy. Armstrong died on August 25, at the age of 82. He commanded the Apollo 11 spacecraft that landed on the Moon on July 20, 1969; and an estimated 600 million people witnessed, by television or radio, as he became the first man to set foot on its surface.

  • International Astronomical Union Approves Names for Nine Mercury Craters  →

    08.09.12 - The International Astronomical Union (IAU) recently approved a proposal from the MESSENGER Science Team to assign names to nine impact craters on Mercury. The IAU has been the arbiter of planetary and satellite nomenclature since its inception in 1919. In keeping with the established naming theme for craters on Mercury, all of the newly designated features are named after famous deceased artists, musicians, or authors or other contributors to the humanities.

  • MESSENGER Marks 8th Anniversary of Launch  →

    08.03.12 - The MESSENGER spacecraft launched eight years ago today — on August 3, 2004 — embarking on a six-and-a-half year journey to become the first spacecraft to orbit Mercury. The spacecraft's 4.9-billion mile (7.9-billion kilometer) cruise to history included 15 trips around the Sun, a flyby of Earth, two flybys of Venus, and three flybys of Mercury.
