When NASA's Magnetospheric Multiscale (MMS) mission launched from Cape Canaveral Air Force Station, Florida, on Thursday, March 12, it delivered a four-spacecraft experiment into Earth orbit that will study an important phenomenon called magnetic reconnection. Aboard each of those spacecraft is an Energetic Ion Spectrometer (EIS) instrument, designed and built by the Johns Hopkins University Applied Physics Laboratory (APL) in Laurel, Maryland.

These two infrared images of C/2013 (Comet Siding Spring) were taken by the Compact Reconnaissance Imaging Spectrometer for Mars (CRISM) aboard NASA’s Mars Reconnaissance Orbiter (MRO) on Oct. 19, 2014. Comet Siding Spring — an Oort Cloud comet that may contain material from the formation of the solar system some 4.6 billion years ago — was making its first voyage through the inner solar system. CRISM and many other instruments and spacecraft combined to provide an unprecedented data set for an Oort Cloud comet.

Scientists have detected magmatic water — water that originates from deep within the Moon's interior — on the surface of the Moon. These findings, published in the August 25 issue of Nature Geoscience, represent the first such remote detection of this type of lunar water, and were arrived at using data from NASA's Moon Mineralogy Mapper (M3).

The Johns Hopkins University Applied Physics Laboratory (APL) and the Armed Forces Health Surveillance Center (AFHSC) have released the Suite for Automated Global Electronic bioSurveillance (SAGES), a collection of flexible, open-source software products developed for electronic disease surveillance in all settings.

Scientists have created the first global topographic map of Saturn's moon Titan, giving researchers a valuable tool for learning more about one of the most Earthlike and interesting worlds in the solar system.
