"Fat Earth Theory' - How Earth's Shape Changes Spacecraft Orbits
A follow on the small effect of the oblateness of the earth is enough to make satellite orbits precess around the planet. And furthermore how this effect can be exploited for a special class of orbits called sun synchronous orbits.
Rimworld has firmly established itself as the nearest thing to a sci-fi version of Dwarf Fortress with a developer who just keeps adding new features and a modding community that more than keeps up. It's now been launched on steam with full workshop support for the price of $29.99

In 2018 I visited Hawaii's Big Island and saw a huge lava lake on the summit of Kilauea, days after I left the activity got so intense the park was closed. There were earthquakes and then a new set of volcanic fissures opened up under the neighborhood of Leilani Estates. Ultimately Fissure 8 would effuse record amounts of lava in a very short time, creating rivers of lava that reached the sea, covering many homes and also creating new land before the eruption ceased.
So when I went back to Hawaii this year I really wanted to get as close as possible to the site of this event. As it turns out, there are tours that take you onto the devastation zone, some are pricey professional operations, others are locals who add their own experiences and you can literally rent a vacation home that's right next to the cooling lava flows.
Thanks to Melissa at Fissure 8 tours for giving the neighborhood level view of this.

Lots of the imagery here was created by the USGS and you can track the latest views of Kilauea from their site:

The pilots of Virgin Galactic's VSS Unity reached an altitude of 82.7km this morning, which is high enough for the FAA to award them commercial astronaut wings.
