An international team of researchers has conducted a long-term experiment aboard the International Space Station to test the effect of space radiation on mouse embryonic stem cells. Their findings will contribute to helping scientists better assess the safety and risks related to space radiation for future human space flights.
The team published their findings in the journal Heliyon on August 18, 2022.
In their study, the team performed a direct quantitative measurement of the biological effect of space radiation by launching frozen mouse embryonic stem cells from the ground to the International Space Station, exposing them to space radiation for over four years, and quantifying the biological effect by examining chromosome aberrations.

If there ever was life on Mars - and that's a huge "if" - conditions during the planet's infancy most likely would have supported it, according to a study led by University of Arizona researchers. Dry and extremely cold, with a tenuous atmosphere, today's Mars is extremely unlikely to sustain any form of life at the surface.

Virgin Orbit, a US company which provides launch services for satellites, has announced that the first orbital space mission from the UK will blast off from Cornwall. The rocket, which will carry nine satellites, along with a launch aircraft have been delivered by an RAF C-17 - a military, heavy-lift strategic transport plane.
This is primed to be a new phase for the UK and its involvement

Curiosity is focused on wrapping up the drill campaign at the Canaima site before hitting the road again. Curiosity started out with an unexpected 10% surplus in energy known as a "power gift." This two-sol plan will allow Curiosity to complete the Canaima drilling activities before driving away along the Mount Sharp Ascent Route (MSAR).
One planned activity is to analyze the Canaima drill

Increasing levels of CO2 in the Earth's atmosphere will result in a long-term decline in air density at high altitudes, according to new research from British Antarctic Survey. Such decreased density will reduce drag on objects orbiting in the upper atmosphere, between 90 and 500 km altitude, extending the lifetime of space debris and elevating the risk of collisions between debris and satellite

When the sun goes down and lights go on - or not - a multitude of data can be gathered by satellite from the night sky, giving insights into the dynamic human activities happening at the surface.
With remote sensing, things like land use changes, urban development, and forest management can be reliably and accurately measured by daylight. At nighttime, we can gather different kinds of data
