Astronauts stranded in space: Unexpected eight-month stay highlights risks of space exploration

Astronauts Butch Wilmore and Suni Williams took off for the International Space Station in June. The test flight aboard Boeing's Starliner was supposed to last a week, but they have yet to return.
Helium leaks and issues with the control thrusters were discovered with the spacecraft, making a safe return to Earth impossible, according to NASA.
Instead, the pair will return to Earth with the crew of an upcoming SpaceX mission, which means they will not be back until February.
But a weeklong trip turning into an eight-month journey is par for the course when it comes to space exploration, Northeastern University experts say.
New Horizons spacecraft measurements shed light on the darkness of the universe

Just how dark is deep space? Astronomers may have finally answered this long-standing question by tapping into the capabilities and distant position of NASA's New Horizons spacecraft, by making the most precise, direct measurements ever of the total amount of light the universe generates.
More than 18 years after launch and nine years after its historic exploration of Pluto, New Horizons is more than 5.4 billion miles (7.3 billion kilometers) from Earth, in a region of the solar system far enough from the sun to offer the darkest skies available to any existing telescope—and to provide a unique vantage point from which to measure the overall brightness of the distant universe.

The Copernicus Sentinel-2C satellite is set for liftoff on 4 September on the last Vega rocket from Europe’s Spaceport in Kourou, French Guiana.
This recording is of a media briefing held on 29 August 2024 to offer journalists the possibility to learn more about the Sentinel-2 mission and the last flight of Vega, Europe’s nimble rocket specialising in launching small scientific and Earth observation spacecraft such as to sun-synchronous polar orbits, following the Sun.
The Sentinel-2 mission is based on a constellation of two identical satellites, Sentinel-2A and Sentinel-2B, flying in the same orbit but 180°

Florida Tech astrobiologist Manasvi Lingam has asked life's biggest questions from a young age. Though he can't recall his exact queries, he says his interests were perfectly consistent with those of other children: dinosaurs and aliens.
On bus rides with his family, he would pepper his parents with questions about the mysteries of the universe. On long walks with his grandfather, he would Locked in a glacier, viruses adapted to survive extreme weather

Ancient viruses preserved in glacial ice hold valuable information about changes in Earth's climate, a new study suggests. For decades, the Guliya Glacier, located above 6000 metres in the far northwestern Tibetan Plateau, has been one of the richest archives available to scientists to investigate large-scale paleoclimate shifts.

Scientists have been exploring the potential of injecting sulfur dioxide into the stratosphere as a method to reflect solar heat and mitigate the effects of global warming. However, there is a growing need to ensure that these solar geoengineering strategies are assessed not only for their cooling potential but also for their technical viability and possible ecological and societal impacts.
