It is always thrilling to see relics of human exploration out there on other worlds. Today, the Lunar Reconnaissance Orbiter Camera team posted some new photos of two defunct spacecraft: the Luna 17 lander and the Lunokhod 1 rover. I've posted images of the two craft before, but the ones released today are much better.

It's always awe-inspiring to see our great world as just a tiny spot within vast space. The latest spacecraft to get such a view of Earth and the Moon is the Jupiter-bound Juno.

Here's a very pretty picture to start off the week: a really gorgeous fresh crater on the lunar farside. There's nothing particularly unusual about this crater; it's just recent and fresh so there's a mesmerizing amount of detail in the feathery patterns of the ejecta that fans outward from it.

In a paper recently published in the Journal of Geophysical Research, Georgiana Kramer and several coauthors performed a careful comparison of two data sets that seem like they're measuring the same things, so you'd think that the measurements they took would match between the two instruments. But they don't quite match.
