NASA will host a media teleconference at 2 p.m. EDT on Thursday, September 29, to discuss new data and images from the first spacecraft to orbit Mercury.

Calibrated data from all seven of MESSENGER's science instruments, plus radio science data from the spacecraft telecommunications system, are included in this release.

Today the MESSENGER spacecraft emerged unscathed from the second of four "hot seasons" expected to occur during its one-year primary mission in orbit around Mercury.

Louise Prockter, a planetary scientist at the Johns Hopkins University Applied Physics Laboratory (APL) in Laurel, Md., has been elected a fellow of the Geological Society of America.

MESSENGER Co-Investigator Louise Prockter has been elected a fellow of the Geological Society of America (GSA).

A Johns Hopkins Applied Physics Laboratory (APL) instrument that will delve into the dynamics of the solar system’s largest planetary magnetic field was launched today aboard NASA’s Juno spacecraft.

The Johns Hopkins University Applied Physics Laboratory (APL) in Laurel, Md., is advising the Missile Defense Agency as MDA develops a plan for streamlined production and fielding of a future space-borne sensor known as the Precision Tracking Space System (PTSS).

Seven years ago, on August 3, 2004, MESSENGER left Earth aboard a three-stage Boeing Delta II rocket to begin a journey that would take it more than 15 laps through the solar system, through six planetary flybys, and ultimately into orbit around Mercury.

The MESSENGER spacecraft continued to fine-tune its orbit around Mercury yesterday afternoon when mission controllers at the Johns Hopkins University Applied Physics Laboratory (APL) in Laurel, Md., successfully executed the second orbit-correction maneuver of the mission.

Scott Murchie of the Johns Hopkins University Applied Physics Laboratory (APL) in Laurel, Md., principal investigator for the Compact Reconnaissance Imaging Spectrometer for Mars (CRISM) instrument, has been awarded the NASA Distinguished Public Service Medal, the highest honor that NASA bestows to an individual working outside the government. Additionally, both the CRISM instrument and science teams were awarded the NASA Public Service Group Achievement Award.
