Rocket Roundup for April 21, 2021
In this week’s Rocket Roundup, host Pamela Gay presents a suborbital Blue Origin launch, the return of Soyuz MS-17, a hovering Ingenuity drone, and an Earth Day special on Earth observatories. Plus, this week in rocket history, we look back at STS-31, which launched from the Kennedy Space Center on April 24th, 1990.
Star Formation Occurs in Competitive Environment
A survey of the stellar nursery in the Orion Nebula Cluster provides evidence that stars compete for material and their size depends on what they gather rather than their initial core size. Plus, NASA mission updates, fast radio bursts, neutron stars, visible novae, and mountain building in the Andes.
Another Potential Dark Matter Particle Isn’t Found
Researchers looked for a slowdown in black hole rotational speeds due to the collection of ultralight bosons, but they found nothing, eliminating the hypothetical particle from the list of possible dark matter particles. Plus, neutrino hunting, neutron stars, a space hurricane, and our review of some delightfully nerdy apparel.
Exoplanetary Atmospheres and How to Understand Them
Today’s news examines many of the ways in which scientists are trying to understand Earth’s atmosphere as well as the atmospheres of exoplanets, mostly in the hopes of figuring out the best way to tell if there is life on another world. Plus, sixty years of fusion power and this week’s What’s Up.
X-ray Surges Found Along With Radio Bursts From Crab Nebula
Data analyzed from the NICER telescope aboard the ISS contains evidence of X-ray boosts accompanying radio burst detections, releasing more energy than expected as “giant radio pulses”. Plus, machine learning, intraterrestrial life, all the volcanoes, and updates on SN15 and Ingenuity.
Rocket Roundup for April 14, 2021
In this week’s Rocket Roundup, host Annie Wilson presents *checks notes* yet another Starlink launch from SpaceX, a Chinese launch, a crewed Russian launch, and the resulting capsule shuffle at the ISS. Plus, this week in rocket history, we celebrate the launch of Vostok 1 and cosmonaut Yuri Gagarin, the first human to travel into outer space, on April 12th, 1961.
