Rocket Roundup for April 28, 2021

Apr 30, 2021 | Crewed Space, Daily Space, Exoplanets, Mars, Random Space Fact, Rockets, ROSCOSMOS, Soyuz, Space China, Space History, Spacecraft, SpaceX

This week, the entire team gathers to share stories on Crew-2, another OneWeb launch, NROL-82, and a Chinese launch. Plus, this week in rocket history, we look back at the launch of NASA’s TESS on April 18th, 2018.

End-Permian Extinction Lasted Ten Times Longer on Land Than Water

The biggest mass extinction event on Earth occurred at the end of the Permian period, resulting in the extinction of 95% of marine life and 80% of terrestrial life. Now, scientists have found that the terrestrial portion of the event lasted nearly ten times as long as the ocean version. Plus, a spaghettified star, the search for Moon Trees, all about Mars, and new works on dark matter and dark energy.

Percy Rover’s MOXIE Extracts Oxygen From Atmosphere

In another first for NASA’s Perseverance rover, a cube-shaped instrument called MOXIE, or Mars Oxygen In-Situ Resource Utilization Experiment, has successfully converted some of Mars’ atmospheric carbon dioxide into oxygen. Plus, a wild roundup of stories including exoplanets, sky maps, fast radio bursts, meteorites, and the problem with symmetry.

Rocket Roundup for April 21, 2021

Apr 23, 2021 | Blue Origin, Crewed Space, Daily Space, Earth, Mars, Random Space Fact, Rockets, ROSCOSMOS, Soyuz, Space History, Spacecraft

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

Apr 22, 2021 | Asteroids, Bennu Mapper, Climate Change, Daily Space, Earth, Fast Radio Bursts, Mars, Neutron Stars / Pulsars, OSIRIS-REx, Spacecraft, Star Forming Region, Stars, Supernovae

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

Apr 20, 2021 | Cosmology, Dark Matter, Earth, Galaxies, Physics, Supermassive Black Holes

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.
