Venus Volcanism is Erupting in the Literature

Another big topic of discussion at LPSC seemed to be Venus. I say "seemed" because I’m sure the actual big topic of discussion was proposed budget cuts, which could be as much as 50%, but there was no definitive information on budget cuts, so that is more a big topic for gossip than for actual fact-based discussion. So let’s look at Venus. The most recent missions to Venus were Japan’s Venus Climate Orbiter, which studied the Venusian cloud cover from 2015 to 2024, and ESA’s Venus Express, which also studied Venus’s atmosphere, and orbited from 2006 to 2015. Together, these 2 missions...

Calculating Pluto’s Oceans

While amazing data is the start of amazing research, it takes a lot of calculations and models to truly understand what the data mean.  Nine years after the New Horizons mission flew past Pluto and discovered it has mountains of ice, and a strangely cracked landscape,...

Lucy’s Discovered Dinkinesh Throws Rocks

We often find ourselves saying that science moves at that rate of technology. With new telescopes and spacecraft we can get new views on the universe. And some of them are weirdly unexpected. Back in November 2023, the Lucy mission flew past the asteroid Dinkinesh on...
