SpaceX launches mission to return stranded astronauts

SpaceX launches rescue mission to return stranded astronauts

A SpaceX rocket soared into the sky Saturday with two passengers on board, leaving two seats empty to return American astronauts who have been stranded for months on the International Space Station, NASA said.
The Falcon 9 rocket took off at 1:17 pm (1717 GMT) from Cape Canaveral, Florida. It used a new launch pad, the pad's first use for a crewed mission.
"Congrats to @NASA and @SpaceX on a successful launch," NASA chief Bill Nelson said in a post on X. "We live in an exciting period of exploration and innovation in the stars."
On board were NASA astronaut Nick Hague and Russian cosmonaut Alexander Gorbunov.
When they return from the space station in February, they will bring back two space veterans—Butch Wilmore and Suni Williams—whose stay on the ISS was prolonged for months by problems with their Boeing-designed Starliner spacecraft.

Fireworks forecast if comet survives risky sun flypast

A comet is expected to risk having its tail clipped on Friday by flying perilously close to the sun, promising fireworks next month should it survive the fraught flypast.
Astronomers believe the Tsuchinshan-ATLAS comet has been hurtling headfirst through the void of space towards the center of the solar system for millions of years.
Named for the Chinese observatory and South African program which detected and confirmed its existence in 2023, the ball of rock and ice may have formed at a distance up to 400,000 times that between Earth and the sun, models suggest.
Up till now, you had to be in the southern hemisphere to hope to see it with the naked eye.
But on Friday evening it is projected to cross as close to the sun as it will get, before returning towards Earth.

Lunar dust dynamics: Unveiling the charging properties and particle behavior of Chang'e-5 samples in an electric field

A study published in Engineering has shed new light on the behavior of lunar regolith particles under the influence of an external electric field, a discovery that could revolutionize space exploration and lunar resource utilization. The research, conducted by a collaborative team of scientists from the Qian Xuesen Laboratory of Space Technology, Tsinghua University, and other institutions, focuses on the charging properties and particle dynamics of lunar samples brought back by China's Chang'e-5 mission.
Scientists begin testing space thruster that could boldly go where no one has gone before

Deep space exploration might no longer be confined to sci-fi after scientists began testing a rocket thruster which promises to boldly go further than ever before.
Astro engineers from the University of Southampton are trialing a new propulsion system which can power spaceships through the stars using any type of metal as fuel.
They say this means crafts fitted with the technology could fly indefinitely by refilling their tanks using minerals harvested from asteroids or far-off moons.
Lead scientist Dr. Minkwan Kim, from the University of Southampton, has been tasked with testing the propulsion system in his labs to measure its thrust.
He said the tech could help spaceships and probes travel to regions of the universe previously thought unreachable.
Dr. Kim added, "Spacecraft have limited amounts of fuel because of the enormous cost and energy it takes to launch them into space.
"But these new thrusters are capable of being powered by any metal that can burn, such as iron, aluminum or copper.
