Instead of following accounts that post space images without proper credit, or flat out get the captions/credit wrong like the example @doug_ellison notes here, follow these folks instead: A thread. (1/n)

China's Zhurong rover released its first images from the surface of Mars! It touched down in Utopia Planitia, in the northern plains of Mars.

Let's take a little tour of Utopia Planitia today.

Michael Byers: Since the 2007 Chinese anti-satellite weapon test, not a single nation has tried a similar test b/c nations realize that generating more space debris harms EVERYONE, not just the nation whose satellite was targeted. #OSI2018

More info: space.com/19450-space-ju… The overarching theme of this panel has revolved around "Kessler Syndrome": Density of objects in low Earth orbit increases → collisions b/t objects cause a cascade effect → collisions generate space debris that increase the likelihood of further collisions. #OSI2018
