HiRISE isn’t just amazing for capturing the Martian surface, here’s Jupiter seen from Mars as we wait for the release of data on interstellar comet 3I/ATLAS

NASA's just-launched ESCAPADE mission is trying out a novel trajectory to Mars, one that's slower but allows much more flexible launch dates. The flight path also provides a bonus science session at the L2 equilibrium point near Earth. 🧪🔭

Avi Loeb's calculations about 3I/ATLAS are 100% wrong because he has never understood that dust in the tail(s) responds to solar radiation pressure. Solar wind shapes the ion tail. But the radiation pressure is about 1000 times larger than the solar wind ram pressure, for particles that feel it.

My view is this: I think the deal stinks. Now, if it passes and they successful protect ACA subsidies in December, then I'll gladly admit I was wrong. If they don't, then I think that there is not real point in supporting except for trying to replace it from the inside. They're just a useful foil.

LOL, I was thinking Voyager 2. But I accidentally wrote Voyager 1. An edit feature would be nice.

The jagged boulders behind the Viking 2 lander, seen in 1977. No lander will likely ever have to land with the limited data on the nature of the surface that the Vikings had to deal with, and Viking 2 was really lucky to touch down here safely.

The map of "Luna Incognita," the sliver of the moon near the south pole missed by the missions of the 1960s and 70s, produced by the Association of Lunar and Planetary observers around 1990, which combined spacecraft and telescopic images. I was involved in the the final verification phase of it.

Saturn from the Hubble Space Telescope in June of 2018. The color data used here extends from near UV to near IR, which is why the intensity of the features on the Saturnian disk seems more pronounced.
