Quasars Help Pinpoint the End of Reionization Epoch
Using the radiation signatures of quasars, scientists have determined when the era of reionization ended in our universe – about 1.1 billion years after the Big Bang. Plus, an update on NASA’s MAVEN spacecraft, new Hubble and Chandra images, and This Week in Rocket History is the TIROS-5 weather satellite.

Rocket Roundup for March 24, 2021
In this week’s Rocket Roundup, host Annie Wilson presents one Russian launch and Rocket Lab’s “They Go Up So Fast”. Plus, this week in rocket history, we look back at Voskhod 2, which launched from the Baikonur Cosmodrome in Kazakhstan on March 18, 1965.
Iceland Has a New Volcanic Fissure Erupting in Fagradalsfjall
After much “will it / won’t it” over the last few weeks in the wake of increased (and then decreased) seismic activity, an eruption in Iceland finally started with a brand new fissure near Fagradalsfjall. No lives are threatened, so Pamela is ecstatic. Plus, arctic methane, a new basalt type, spiders on Mars, Titan’s atmosphere, and an interview with PSI scientist Dr. Nick Castle about volcanoes
LPSC: Studying Microorganisms Trapped in Salt as Martian Analog
We interview a pair of scientists who have examined microorganisms embedded in halite crystals to determine the feasibility of finding similar evidence of past life in return samples from Mars. Plus, ‘Oumuamua, Bennu, Ryugu, winds on Jupiter and a space jellyfish.
LPSC: Water on Mars Never Left After All
New research shows that most of the water once thought to have escaped Mars is actually still trapped in the minerals in the crust. And life may still be present and accessible on the red planet. Plus, a cosmic lens, Bennu, volcanoes, more news from LPSC 2021, and our weekly What’s Up.
Rocket Roundup for March 17, 2021
In this week’s Rocket Roundup, host Annie Wilson presents not one but two SpaceX Starlink launches as well as two Chinese launches. Plus, this week in rocket history, we look back at the Gemini 8 mission, which launched March 16th, 1966.
LPSC: All the Planetary News You Can Handle
Monday was the first day of the Lunar and Planetary Science Conference, and we are going to spend at least the next two weeks sharing as much science as possible. The conference is taking place virtually this year, and of course, Mars is the big focus. Plus icy worlds, volcanic worlds, and exoplanets, and we’re bringing you a little of everything.
