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.
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.
Historically, human spaceflight was described using the words "manned" and "unmanned," but NASA has shifted to using gender-neutral words to describe human space exploration, even though the Associated Press has not. A recent discussion on Twitter among science writers and scientists highlighted some alternatives.
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.
This is the first in a series of posts in which scientists share favorite planetary science plots. For my #FaveAstroPlot, I explain what you can see when you look at how asteroid orbit eccentricity and inclination vary with distance from the Sun.
Last Friday I posted an image containing 18 samples of terrain, all shown at the same scale. Were you able to figure out which square was which? Here are the answers.
