OSIRIS-REx Views The Earth During Flyby
September 26, 2017 – NASA’s OSIRIS-REx spacecraft took this color composite image of Earth using its MapCam camera on September 22, 2017. This image was taken just hours after the spacecraft completed its Earth Gravity Assist at a range of approximately 106,000 miles (170,000 kilometers). MapCam is part of the OSIRIS-REx Camera Suite (OCAMS) operated by the University of Arizona. Read More
Eclipse 2017: A Celestial Achievement For Public Libraries
September 26, 2017 – 2.1 million pairs of eclipse glasses were distributed free through public libraries in the U.S. for the solar eclipse event on August 21, 2017. 7,100 organizations, including public library branches, bookmobiles, tribal libraries, library consortia, and state libraries, received a package of free safe-viewing glasses, plus a 24-page information booklet on how best to do public outreach programs about the eclipse. This was the single largest distribution of free glasses in the entire country and reached more people with glasses and information than any other educational effort for the 2017 eclipse. It is projected that this library eclipse project allowed 6 million people to observe the event safely. Read More

End Of Mission Blues With Dr. Storrie-Lombardi
Dr. Lisa Storrie-Lombardi returns to the show to discuss NuSTAR, Spitzer, and what it feels like to end a mission you’ve been working on for decades. Cassini’s Grand Finale has us reflecting on the upcoming demise of the Spitzer Space Telescope.
NASA’s Near-Earth Asteroid CubeSat Goes Full Sail
NASA’s Near-Earth Asteroid Scout, a small satellite the size of a shoebox, designed to study asteroids close to Earth, performed a full-scale solar sail deployment test at ManTech NeXolve’s facility in Huntsville, Alabama, Sept. 13. The test was performed in an indoor clean room to ensure the deployment mechanism’s functionality after recent environmental testing.
Video: Experiencing “Mars” Through HI-SEAS

Want to learn more about life on a simulated Mars mission? Hear from Josh Ehrlich – a Lockheed Martin engineer on the Orion spacecraft who traded in tech for a trowel as the resident botanist of the fifth Hawaii Space Exploration Analog and Simulation (HI-SEAS) study. The video journal was recorded just days before the mission ended Sept. 17, 2017.
A series of parabolic flights from Zero Gravity Corporation (ZERO-G) in March 2017 enabled researchers to test and validate the performance of two technologies from NASA’s Jet Propulsion Laboratory (JPL): Comet Sample Verification System and Biosleeve Gesture Control Interface for Telerobotics.
Helicopter Test For Jupiter Icy Moons Radar
A long radar boom that will probe below the surface of Jupiter’s icy moons has been tested on Earth with the help of a helicopter. ESA’s Jupiter Icy Moons Explorer, Juice, is scheduled for launch in 2022, arriving seven years later. It will study Jupiter’s turbulent atmosphere and vast magnetic fields, as well as the planet-sized moons Ganymede, Europa and Callisto.
Internship And Postdoc Opportunities At NASA Ames
The Kepler/K2 Science Center at NASA Ames is now accepting applications for paid internships via the NASA Internships Portal. The program enables students to gain experience in the scientific operations of a high-profile space photometry mission. PhD and graduate students already using Kepler or K2 data as part of their research projects are particularly encouraged to apply. Also at NASA Ames, the NASA Postdoctoral Program is accepting applications to work on high-resolution imaging of K2 and TESS exoplanet host stars with Steve Howell and the analysis of transiting planets to be observed by JWST with Tom Greene.

Scientists are already building the next generation’s ChemCam with impressive upgrades and brand new spectral capabilities for the NASA Mars 2020 rover, named for the year of its scheduled launch. In addition to a faster LIBS system, the SuperCam will feature an entirely new conduction-cooled laser system to provide the non-destructive analysis ability of Raman spectroscopy, capable of detecting carbon-based signatures of organic materials.
We conducted an extensive search for dust or debris rings in the Pluto-Charon system before, during, and after the New Horizons encounter in July 2015. Methodologies included attempting to detect features by back-scattered light during the approach to Pluto (phase angle α ∼ 15◦), in situ detection of impacting particles, a search for stellar occultations near the time of closest approach, and by forward-scattered light imaging during departure (α ∼ 165◦). An extensive search using the Hubble Space Telescope (HST) prior to the encounter also contributed to the final ring limits.
Cosmic Kittens: Saturn Features Get Feline Names
If you know anything about Saturn, you probably know that it’s a planet surrounded by rings. But did you know that it’s also surrounded by cats? NASA’s Cassini spacecraft, which plunged into Saturn on Sept. 15, has discovered at least 60 “kittens” orbiting in Saturn’s F ring. These features aren’t actually young cats, but Cassini scientists have been naming them after kittens, mostly just for fun.

Soft, frisbee-like robots may one day be flying around asteroids, according to a University of Colorado scientist who won a NASA innovation grant to study the idea. Jay McMahon tells Colorado Matters the “soft bot” could adhere to an asteroid using something called van der Waals principles — relatively weak forces that allow a gecko to climb walls, for example.
