NASA-sponsored small satellites will soon have dedicated rides to space, thanks to a new, light-duty rocket program called Venture Class Launch Services, or VCLS.
Neil deGrasse Tyson to Receive Cosmos Award for Outstanding Public Presentation of Science
Famed astrophysicist Neil deGrasse Tyson will accept The Planetary Society’s Cosmos Award for Outstanding Public Presentation of Science in Pasadena, California on October 24, 2015.
Charon in 3D
Last week, the pile of New Horizons LORRI camera raw image releases included nine frames from a high-resolution mosaic on Charon. Together with the color MVIC view, they make a 3D global photo of Pluto's moon. Other recently released goodies include a global backlit color image of Pluto and the first image that resolves the tiny moon Styx.

Telerobotics: Unifying Human and Robotic Spaceflight
Telerobotics—with humans nearby—just might be the perfect unification of human and robotic spaceflight. Two groups at NASA and ESA are working to make this fledgling technology commonplace.
How do you pronounce "Ryugu?"
With some help from astronomer Elizabeth Tasker and a group of astronomy graduate students from the University of Hokkaido, I learn how.
Mars Orbiter Mission update: A year at Mars
A couple of weeks ago, there was a flurry of rumor that ISRO was ready to announce some results from its Mars Orbiter Mission's methane sensor. The Indian space agency held a press event for the one-year-in-orbit anniversary of Mars Orbiter Mission and released a book containing mission photos, but did not unveil any new scientific results.

Historically, human spaceflight was described using the words
Hayabusa2's target asteroid has a name!
JAXA announced today the results of the naming contest for Hayabusa2. The target of the sample-return mission, formerly known as 1999 JU3 and still numbered 162173, is now named 162173 Ryugu.
New Horizons releases new color pictures of Charon, high-resolution lookback photo of Pluto
Now that New Horizons is regularly sending back data, the mission is settling into a routine of releasing a set of captioned images on Thursdays, followed by raw LORRI images on Friday. The Thursday releases give us the opportunity to see lovely color data from the spacecraft's Ralph MVIC instrument. This week, the newly available color data set covered Charon.
