I don't know what to make of this change, but I worry that in this "rush, rush" environment we may trample, metaphorically and literally, on potentially great science.

NASA directive might increase the odds of contaminating Mars
The new push loosens U.S. regulations for sterilizing spacecraft bound for the Red Planet and calls for modernizing the science of “planetary protection”

10 years since Rosetta ended, time flies ! And now @ESA's next mission to a small body (Hera) is about to reach its destination. Many of us who were involved with Rosetta are working on Hera. It's a great family of scientists, engineers, and space missions :) #PlanetaryScience
Ten years ago one daring spacecraft made a final descent 🥹
On 30 September 2016, the Rosetta mission concluded with a controlled impact onto Comet 67P/Churyumov–Gerasimenko, taking one last image.
