NASA Selects 2 Missions to Study ‘Lost Habitable’ World of Venus

Poor Trident :(. I was sure that Trident and one Venusian mission would be picked, but now it looks like we aren’t going to visit Triton and Neptune again for another couple of decades, and we have lost a chance to see Triton’s plumes for at least a century (they go dormant at a certain point of Neptune’s orbit.)


as an undergraduate who hopes to study Venus, it’s hard to put into words how this makes me feel. Venus is finally getting the attention it deserves. When you step back and think about it, it’s shocking how little we know about our closest planet. Nasa hasn’t sent a mission since Magellan was launched in the 80s. The surface is mapped to a dismal resolution of 100 metres per pixel – enough to resolve mountains and hills but not much else. Nobody’s landed on Venus since the USSR’s last lander in the 80s. *We don’t even know what rock Venus’s surface is made out of.* Did Venus once have oceans like Mars and Earth? are volcanoes erupting on Venus now? Does Venus’s atmosphere have life **today**? We never checked. Now compare this to Mars, which has been the focus of ~a dozen missions over the past 20 years. With Nasa’s Mars missions we have gloriously detailed 25 cm/pixel orbital imagery, we have 3 rovers driving around looking for signs of life etc etc. Venus scientists have been waiting half a lifetime for this announcement today. There are soooo many questions to answer and new places to explore. Because we know so little about Venus, these missions will be extraordinarily scientifically productive, because of the leap in technology since we last visited. Frankly, it’ll be as if we’re discovering a new planet from scratch. and I can’t wait 😀


Happy they chose DAVINCI+. But I’m sad that they didn’t choose TRIDENT over VERITAS.


The phosphine findings must have influenced this, right? But wasn’t a lot of doubt cast on those findings recently? I know there was a lot of talk about the two Venus missions out of the four being a shoo-in originally after those findings.


That’s good. Venus is lonely and needs a friend since he doesn’t have a happy little moon to keep him company.
