Pasadena, CA – Beginning this month, NASA is launching a suite of six next-generation, Earth-observing small satellite missions to demonstrate innovative new approaches for studying our changing planet.
These small satellites range in size from a loaf of bread to a small washing machine and weigh from a few to 400 pounds (180 kilograms). Their small size keeps development and launch costs down as they often hitch a ride to space as a “secondary payload” on another mission’s rocket — providing an economical avenue for testing new technologies and conducting science.

Pasadena, CA – The next target for NASA’s New Horizons mission — which made a historic flight past Pluto in July 2015 — apparently bears a colorful resemblance to its famous, main destination.
NASA’s Hubble Space Telescope data suggests that 2014 MU69, a small Kuiper Belt object (KBO) about a billion miles (1.6 billion kilometers) beyond Pluto, is as red, if not redder, than Pluto. This is the first hint at the surface properties of the far-flung object that New Horizons will survey on January 1st, 2019.

Huntsville, AL – Scientists using NASA’s Chandra X-ray Observatory have made the first detections of X-rays from Pluto. These observations offer new insight into the space environment surrounding the largest and best-known object in the solar system’s outermost regions.
While NASA’s New Horizons spacecraft was speeding toward and beyond Pluto, Chandra was aimed several times on the dwarf planet and its moons, gathering data on Pluto that the missions could compare after the flyby. Each time Chandra pointed at Pluto – four times in all, from February 2014 through August 2015 – it detected low-energy X-rays from the small planet.
From 9:00am to 11:00am and again from 1:00pm to 3:00pm, hummingbirds were banded by Cyndi Routledge, a master bander who has completed the five-year course taught by the Department of the Interior.
Information gathered at the banding is sent to Laurel, Maryland where a huge data base on hummingbirds is located under the auspices of the United States Geological Survey.

Pasadena, CA – New findings using data from NASA’s Mars Reconnaissance Orbiter show that gullies on modern Mars are likely not being formed by flowing liquid water. This new evidence will allow researchers to further narrow theories about how Martian gullies form, and reveal more details about Mars’ recent geologic processes.
Scientists use the term “gully” for features on Mars that share three characteristics in their shape: an alcove at the top, a channel, and an apron of deposited material at the bottom.

“We’ve just crossed the boundary into Jupiter’s home turf,” said Juno Principal Investigator Scott Bolton of Southwest Research Institute, San Antonio. “We’re closing in fast on the planet itself and already gaining valuable data.”

Greenbelt, MD – New findings based on a year’s worth of observations from NASA’s Van Allen Probes have revealed that the ring current – an electrical current carried by energetic ions that encircles our planet – behaves in a much different way than previously understood.
The ring current has long been thought to wax and wane over time, but the new observations show that this is true of only some of the particles, while other particles are present consistently.
Using data gathered by the Radiation Belt Storm Probes Ion Composition Experiment, or RBSPICE, on one of the Van Allen Probes, researchers have determined that the high-energy protons in the ring current change in a completely different way from the current’s low-energy protons.
Washington, D.C. – NASA’s MESSENGER mission has unveiled the first global digital elevation model (DEM) of Mercury, revealing in stunning detail the topography across the entire innermost planet and paving the way for scientists to fully characterize Mercury’s geologic history.
The global topographic model is among three new products from the Planetary Data System (PDS), a NASA-funded organization that archives and distributes all of NASA’s planetary mission data to the public.

Pasadena, CA – Volcanoes erupted beneath an ice sheet on Mars billions of years ago, far from any ice sheet on the Red Planet today, new evidence from NASA’s Mars Reconnaissance Orbiter suggests.
The research about these volcanoes helps show there was extensive ice on ancient Mars. It also adds information about an environment combining heat and moisture, which could have provided favorable conditions for microbial life.
Sheridan Ackiss of Purdue University, West Lafayette, Indiana, and collaborators used the orbiter’s mineral-mapping spectrometer to investigate surface composition in an oddly textured region of southern Mars called “Sisyphi Montes.”
Washington, D.C. – A year ago, Pluto was just a bright speck in the cameras of NASA’s approaching New Horizons spacecraft, not much different than its appearances in telescopes since Clyde Tombaugh discovered the then-ninth planet in 1930.
But this week, in the journal Science, New Horizons scientists have authored the first comprehensive set of papers describing results from last summer’s Pluto system flyby.
