Cleveland, OH – When human explorers embark on the journey to Mars, they need to know the natural conditions of the red planet before they arrive. That’s why NASA sends rovers to the surface of Mars to photograph the landscape and operate scientific experiments to understand the habitat for humans or other kinds of life.
One of those future rover missions may host the Martian Aqueous Habitat Reconnaissance Suite (MAHRS), a set of five instruments that can take surface measurements in the search for habitable environments.

Pasadena, CA – The puzzling appearance of an ice cloud seemingly out of thin air has prompted NASA scientists to suggest that a different process than previously thought — possibly similar to one seen over Earth’s poles — could be forming clouds on Saturn’s moon Titan.
Located in Titan’s stratosphere, the cloud is made of a compound of carbon and nitrogen known as dicyanoacetylene (C4N2), an ingredient in the chemical cocktail that colors the giant moon’s hazy, brownish-orange atmosphere.

Pasadena, CA – After more than 12 years studying Saturn, its rings and moons, NASA’s Cassini spacecraft has entered the final year of its epic voyage. The conclusion of the historic scientific odyssey is planned for September 2017, but not before the spacecraft completes a daring two-part endgame.
Beginning on November 30th, Cassini’s orbit will send the spacecraft just past the outer edge of the main rings. These orbits, a series of 20, are called the F-ring orbits. During these weekly orbits, Cassini will approach to within 4,850 miles (7,800 kilometers) of the center of the narrow F ring, with its peculiar kinked and braided structure.

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.

Pasadena, CA – New scenes from a frigid alien landscape are coming to light in recent radar images of Saturn’s largest moon, Titan, from NASA’s Cassini spacecraft.
Cassini obtained the views during a close flyby of Titan on July 25th, when the spacecraft came as close as 607 miles (976 kilometers) from the giant moon. The spacecraft’s radar instrument is able to penetrate the dense, global haze that surrounds Titan, to reveal fine details on the surface.

Greenbelt, MD – Early in the morning of September 1st, 2016, NASA’s Solar Dynamics Observatory, or SDO, caught both Earth and the moon crossing in front of the sun. SDO keeps a constant eye on the sun, but during SDO’s semiannual eclipse seasons, Earth briefly blocks SDO’s line of sight each day – a consequence of SDO’s geosynchronous orbit.
On September 1st, Earth completely eclipsed the sun from SDO’s perspective just as the moon began its journey across the face of the sun. The end of the Earth eclipse happened just in time for SDO to catch the final stages of the lunar transit.

Pasadena, CA – A lonely 3-mile-high (5-kilometer-high) mountain on Ceres is likely volcanic in origin, and the dwarf planet may have a weak, temporary atmosphere. These are just two of many new insights about Ceres from NASA’s Dawn mission published this week in six papers in the journal Science.
“Dawn has revealed that Ceres is a diverse world that clearly had geological activity in its recent past,” said Chris Russell, principal investigator of the Dawn mission, based at the University of California, Los Angeles.

Pasadena, CA – Each year, NASA funds a handful of futuristic concepts to push forward the boundaries of space exploration. These early-stage proposals are selected with the hope of developing new ideas into realistic proofs-of-concept.
From August 23rd to 25th, the NASA Innovative Advanced Concepts (NIAC) symposium will host presentations on 28 proposals, including five from NASA’s Jet Propulsion Laboratory, Pasadena, California.

Edwards, CA – Some interns get coffee. Others might make copies. Not at NASA Armstrong Flight Research Center in California, where a group of students successfully flew a prototype of an aircraft that could one day fly in the Martian atmosphere and send its findings back to Earth.
Called the Preliminary Research Aerodynamic Design to Land on Mars, or Prandtl-M, the small, remotely piloted glider aircraft flew August 11th at Armstrong. It continues an effort that began last year with a mostly different group of students.
Washington, D.C. – Jupiter’s volcanic moon Io has a thin atmosphere that collapses in the shadow of Jupiter, condensing as ice, according to a new study by NASA-funded researchers. The study reveals the freezing effects of Jupiter’s shadow during daily eclipses on the moon’s volcanic gases.
“This research is the first time scientists have observed this remarkable phenomenon directly, improving our understanding of this geologically active moon,” said Constantine Tsang, a scientist at the Southwest Research Institute in Boulder, Colorado. The study was published August 2nd in the Journal of Geophysical Research.
