EVSN: Escape Velocity Space News ·

2022/02/17

Today our view on the universe gets itself an update thanks to the combined efforts of theorists and observers. From new understanding of how galaxies can lose their darkmatter, 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.

Space Junk Hitting the Moon is not From SpaceX

EVSN: Escape Velocity Space News ·

2022/02/15

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.

EVSN: Escape Velocity Space News ·

2022/02/09

SpaceX launched another 49 Starlink satellites last week, but a geomagnetic storm caused by solar activity kept the satellites offline, and 40 of them failed to reach their final orbits after exiting safe mode. They are now deorbiting and breaking up in the Earth’s atmosphere. Plus, asteroid systems, Eta Carina, and this week in rocket history, we look back at Mir Expedition 2.

Mars Could Have Supported Life Longer Than Thought

EVSN: Escape Velocity Space News ·

2022/02/08

A NASA-funded simulation of early Mars revealed that the climate three billion years ago on the red planet was very similar to Earth now, with a stable ocean in the northern hemisphere. This new timeline would have given life another 500 million years to develop. Plus, a dwarf galaxy, Saturn’s aurorae, a Soyuz launch, and an interview with Dr. Adam Szabo, mission scientist for the Parker Solar Probe.

Moons May Be Beneficial to Life Beyond Earth

EVSN: Escape Velocity Space News ·

2022/02/05

New simulations find that to form a moon with a similar size ratio to our own system, certain types of planets are needed. And that type of moon-planet system could then be beneficial to the rise of life on the planet. Plus, a Starlink launch, puffy planets, and training astronauts underwater for spacewalks.

2022/01/27

Scientists using the Murchison Widefield Array in Australia recently discovered an extremely bright source of radio waves, releasing bursts of energy three times an hour. That timing makes the object behave unlike anything else seen to date, leaving the research team with a new mystery to unravel. Plus, everything else is about water today, all over the solar system, and we present this week’s What’s Up segment.

2022/01/26

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

The Curious Case of the Brown Dwarfs at 14 Herculis

EVSN: Escape Velocity Space News ·

2022/01/26

A dynamical analysis of the 14 Herculis system has revealed the existence of two brown dwarf planets orbiting in completely misaligned, eccentric orbits.
