Decades of radiation-based scientific theory challenged

Surprisingly, exposure to a high background radiation might actually lead to clear beneficial health effects in humans, according to Ben-Gurion University of the Negev and Nuclear Research Center Negev (NRCN) scientists. This is the first large-scale study which examines the two major sources of background radiation (terrestrial radiation and cosmic radiation), covering the entire U.S. populatio How asteroid dust helped us prove life's raw ingredients can evolve in outer space

Scientists have long known that certain ingredients are needed to support life, especially water and key organic chemicals like carbon. In recent years, both ingredients have been found on giant asteroids and other celestial bodies.
But, until now, no study had delivered conclusive evidence, based on extraterrestrial samples, to show how and when organic matter was made on the rocks that g SpaceX aims to nail landing of Starship on fourth attempt

SpaceX plans another attempt to fly and land the company's Starship moon and Mars rocket as early as Monday from Boca Chica, Texas.
The rocket company had filed for "no-fly" notices during daylight hours from Friday through Monday around the SpaceX launch facility in the community about 180 miles south of Corpus Christi.

NASA analysis: Earth is safe from asteroid Apophis for 100-plus years
Write a comment
The near-Earth object was thought to pose a slight risk of impacting Earth in 2068, but now radar observations have ruled that out.
After its discovery in 2004, asteroid 99942 Apophis had been identified as one of the most hazardous asteroids that could impact Earth.
Raspberry Pi-powered cybersecurity for future missions, tested on Space Station

One of the cheapest experiments ever flown in orbit has finished operating after 22 months on the International Space Station. Running on a Raspberry Pi Zero costing just a few Euros, ESA’s CryptIC payload was exploring cryptography techniques running on off-the-shelf hardware, to ensure cybersecurity for future low-cost space missions.

Apophis impact ruled out for the first time
Write a comment
New observations of asteroid Apophis – thought to pose a slight risk of impacting Earth in 2068 – rule out any chance of impact for at least a century. After 17 years of observations and orbit analysis, ESA is removing the enormous asteroid from its Risk List.
Light show over US sky likely SpaceX debris re-entering atmosphere
Write a comment
A spectacular display of lights that streamed across the night sky over the US Pacific Northwest was probably debris from a SpaceX mission re-entering the atmosphere, the National Weather Service (NWS) said.
"While we await further confirmation on the details, here's the unofficial information we have so far. The widely reported bright objects in the sky were the debris from a Falcon 9 rocket 2nd stage," NWS Seattle tweeted.
Videos posted on social media showed a thick cluster of glowing dots with blazing trails of light moving slowly across the sky before fizzling out, with users speculating the phenomenon might be a meteor shower or even, jokingly, an alien invasion.
Local media reported multiple sightings just after 9 pm local time, with videos posted online from Washington state and Oregon.
NWS Seattle said the sight was more likely to be caused by space debris rather than a meteor or similar object because the latter would be moving far faster, a conclusion backed up by several meteorologists quoted by local media.
Jonathan McDowell from Harvard's Center for Astrophysics also pointed to the Falcon 9 rocket stage as the source of the firework-like display.
