As we return from our mini-break, we bring you some highlights of stories that happened while we were away, including black holes spiraling toward each other, the possible origin of a fast radio burst, and more information on the demise of the dinosaurs. Plus, Erik Madaus brings us updates on quite a few rocket launches.
Today, our view on the universe gets itself an update thanks to the combined efforts of theorists and observers. From a new understanding of how galaxies can lose their dark matter, to how white dwarfs can be resurrected into helium-burning stars, we have the weird, the wonderful, and in the case of a new lunar tracking system, we even have a touch of the mundane. Plus, this week in rocket history, we look back at STS-82 which serviced the Hubble Space Telescope.
Observers tracking a piece of space debris that is expected to impact the far side of the Moon early in March have now corrected the origin of the object, which isn’t from SpaceX but is from a Chinese Long March 3B involved in the Chang’e 5TI mission. Plus, asteroid 16 Pysche, craters in Wyoming, more launches, and an interview with Katharine Hesse from the TESS mission.
For decades, scientists have been trying to work out just how the Earth got all its water, and the prevailing theory was that comets and asteroids brought it, and we have evidence for that mechanic; however, a new hypothesis has provided evidence that the water was already here, locked away in hydrous minerals in a very iron-poor core. Plus, magnetic fields, subatomic particles, life on the ocean floor, a geology mystery solved, and this week in rocket history covers a space shuttle mission with some really neat science.
Recent observations of twelve different stellar streams around the Milky Way have revealed the effects of dark matter, similar to how lights on a Christmas tree reveal the shape of the tree in dark. Plus, globular clusters, volcanoes, and an interview with Dr. Cathy Olkin from the Southwest Research Institute’s Lucy mission.
The Rocket Roundup team takes a look back at the rockets that launched in 2021, with a review of the statistics and some highlights (including that one telescope that could have ruined Christmas).
