Pasadena, CA – Seasonal dark streaks on Mars that have become one of the hottest topics in interplanetary research don’t hold much water, according to the latest findings from a NASA spacecraft orbiting Mars.
The new results from NASA’s Mars Odyssey mission rely on ground temperature, measured by infrared imaging using the spacecraft’s Thermal Emission Imaging System (THEMIS). They do not contradict last year’s identification of hydrated salt at these flows, which since their 2011 discovery have been regarded as possible markers for the presence of liquid water on modern Mars.

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.

Greenbelt, MD – On August 21st, 2016, contact was reestablished with one of NASA’s Solar Terrestrial Relations Observatories, known as the STEREO-B spacecraft, after communications were lost on October 1st, 2014.
Over 22 months, the STEREO team has worked to attempt contact with the spacecraft. Most recently, they have attempted a monthly recovery operation using NASA’s Deep Space Network, or DSN, which tracks and communicates with missions throughout space.
NASA’s Stennis Space Center
Bay St. Louis, MS – NASA engineers successfully conducted a development test of the RS-25 rocket engine Thursday, August 18th at NASA’s Stennis Space Center near Bay St. Louis, Mississippi. The RS-25 will help power the core stage of the agency’s new Space Launch System (SLS) rocket for the journey to Mars.
A variety of NASA officials and contractor representatives, as well as social and traditional media members, gathered to watch the 420-second test of RS-25 engine No. 0528. NASA is developing the SLS to send humans further into deep space than they have ever traveled, including on the journey to Mars.

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.

Pasadena, CA – In an extensive airborne survey, a NASA-led team has analyzed a previously identified “hot spot” of methane emissions in the Four Corners region of the United States, quantifying both its overall magnitude and the magnitudes of its sources. The study finds that just 10 percent of the individual methane sources are contributing half of the emissions.
Scientists from NASA’s Jet Propulsion Laboratory and Caltech, both in Pasadena, California; the National Oceanic and Atmospheric Administration (NOAA), Boulder, Colorado; and the University of Michigan, Ann Arbor, used two JPL airborne spectrometers to identify and measure more than 250 individual sources of methane.

Pasadena, CA – Like cosmic ballet dancers, the stars of the Pleiades cluster are spinning. But these celestial dancers are all twirling at different speeds. Astronomers have long wondered what determines the rotation rates of these stars.
By watching these stellar dancers, NASA’s Kepler space telescope during its K2 mission has helped amass the most complete catalog of rotation periods for stars in a cluster. This information can help astronomers gain insight into where and how planets form around these stars, and how such stars evolve.

Washington, D.C. – Using public data collected by NASA’s Kepler mission, astronomers have catalogued the planet candidates that may be similar to our third rock from the sun. The tabulation of candidates will help astronomers focus their research efforts in the search for life.
The analysis, led by Stephen Kane, an associate professor of physics and astronomy at San Francisco State University in California, highlights 20 candidates in the Kepler trove that are less than twice the size of Earth and orbit their star in the conservative habitable zone — the range of distances where liquid water could pool on the surface of an orbiting planet.

Greenbelt, MD – Launched five years ago on August 5th, 2011, NASA’s Juno mission maneuvered into orbit around Jupiter on July 4th, 2016, joining a long tradition of discovery at the gas giant.
One of the brightest objects in the night sky, Jupiter has enthralled humans since ancient times. Today, scientists believe that learning more about the planet may be the key to discovering our solar system’s origins and formation.

Pasadena, CA – As Curiosity marks its fourth anniversary (in Earth years) since landing on Mars, the rover is working on collecting its 17th sample. While Curiosity explores Mars, gamers can join the fun via a new social media game, Mars Rover.
On their mobile devices, players drive a rover through rough Martian terrain, challenging themselves to navigate and balance the rover while earning points along the way. The game also illustrates how NASA’s next Mars rover, in development for launch in 2020, will use radar to search for underground water.
