Understanding how efficient solar flares release their energy
Friday, 28 January 2022 07:26
New findings published Jan. 27 in the journal Nature Astronomy have called into question decades of theoretical understanding used by astrophysicists to interpret an observational phenomenon central to understanding energy released during powerful eruptions from the Sun, known as solar flares.

Armed with a new statistical analysis of stellar flares on hundreds of distant stars, scientists are beginning to understand the likelihood that remote "exoplanets" might sustain life in our galaxy, research at the University of Colorado Boulder suggests.
The most-intense flares, which are more complex than previously observed, could have implications for the viability of life on nearby pl Hat-trick for Exolaunch with SpaceX Transporter Missions
Friday, 28 January 2022 07:26
In its third dedicated rideshare mission with SpaceX, Exolaunch, the leading global provider of launch, in-space logistics and deployment services, successfully integrated and launched 29 small satellites from customers across the globe. The company's rideshare clusters aboard the SpaceX Transporter-3 mission were an amalgamation of microsats, cubesats (up to 16U) and PocketQubes.

NASA said Thursday it aims to survey the crater formed when the remains of a SpaceX rocket are expected to crash into the Moon in early March, calling the event "an exciting research opportunity."
The rocket was deployed in 2015 to put a NASA satellite into orbit and its second stage, or booster, has been floating in the cosmos ever since, a common fate for such pieces of space technology. Space Power to revolutionize satellite power using laser beaming
Friday, 28 January 2022 07:26
The University of Surrey and Space Power are tackling the problem of powering satellites in Low Earth Orbit (LEO) during their eclipse period when they cannot see the sun. By collaborating on a space infrastructure project, the joint team will develop new technology which uses lasers to beam solar power from satellites under solar illumination to small satellites orbiting closer to Earth during What wintering squirrels can teach astronauts
Friday, 28 January 2022 07:26
When bears and ground squirrels hibernate in winter, they stop eating, lasting until spring simply on the fat reserves they've stored up in their bodies. Usually, this sort of prolonged fasting and inactivity would significantly reduce the mass and function of muscle, but hibernators don't suffer this fate. How they avoid it, however, has been a mystery.
