human brain: Opportunity rover accomplished its mission and then some! It lasted far longer than we could’ve ever hoped. This should be celebrated, Opportunity did really well.

monkey brain: BUT SHE DIED ALL ALONE AND IN THE DARK AND ON A PLANET ALL THE WAY OUT IN SPACE AWAY FROM HOME!!! DOES SHE KNOW HOW PROUD OF HER WE ARE?! DID SHE THINK WE FORGOT ABOUT HER?! I LOVE HER AND I WANT HER TO BE HAPPY AND TO THRIVE AND I JUST WANT TO HUG HER AND LET HER KNOW HOW MUCH I CARE ABOUT HER!!! WE DIDN’T FORGET ABOUT YOU, OPPY!!! WE LOVE YOU SO MUCH AND I WOULD KILL ANYONE AND EVERYONE JUST FOR YOU TO HAVE PASSED AMONG FRIENDS AND FAMILY HERE ON EARTH!!!

international friends: here’s the deal. South African scientists have been tracking the COVID genome and keeping an eye out for mutations. Most places in the world aren’t doing so. When we announce a new variant, it’s not necessarily from South Africa, we just publicised the fact that we detected it here. And yet, because we’re a country in the Global South, it doesn’t matter that our scientists are incredible and are doing the world a service by tracking and reporting these things, because our ordinary citizens are being blacklisted because of it and being prevented from entering other countries and placed on red lists for no reason
