Four astronauts headed to the International Space Station on Sunday where they will oversee the arrivals of two new rocketships during their half-year stint.
SpaceX's Falcon rocket blasted off from Kennedy Space Center, carrying NASA's Matthew Dominick, Michael Barratt and Jeanette Epps and Russia's Alexander Grebenkin.

Government scientists have cooked up a new concept for how to potentially cool an overheating Earth: Fiddle with the upper atmosphere to make it a bit drier.
Water vapor — water in its gas form — is a natural greenhouse gas that traps heat, just like carbon dioxide from burning coal, oil and gas. So researchers at the National Oceanic and Atmospheric Administration and NASA figure if they can just inject ice high up in the air, water vapor in the upper atmosphere would get a bit drier and that could counteract a small amount of the human-caused warmth.

Turkey's first astronaut returned home to a hero's welcome Monday, portrayed as a symbol of the country's advances in technology and aerospace.
Alper Gezeravci was greeted by bouquet-laden children at Ankara's Esenboga Airport as he returned from a private three-week mission to the International Space Station. In return, he handed out Turkish flags he had carried with him into space.

A handful of centuries-old sponges from deep in the Caribbean are causing some scientists to think human-caused climate change began sooner and has heated the world more than they thought.
They calculate that the world has already gone past the internationally approved target of limiting global warming to 1.5 degrees Celsius (2.7 degrees Fahrenheit) since pre-industrial times, hitting 1.7 degrees (3.1 degrees Fahrenheit) as of 2020. They analyzed six of the long-lived sponges — simple animals that filter water — for growth records that document changes in water temperature, acidity and carbon dioxide levels in the air, according to a study in Monday's journal Nature Climate Change.

An asteroid as big as a skyscraper will pass within 1.7 million miles of Earth on Friday.
Don't worry: There's no chance of it hitting us since it will pass seven times the distance from Earth to the moon.

According to Elon Musk, the first human received an implant from his computer-brain interface company Neuralink over the weekend.
In a Monday post on X, the platform formerly known as Twitter, Musk said that the patient received the implant the day prior and was "recovering well." He added that "initial results show promising neuron spike detection."

Turkey's first astronaut along with a Swede and Italian launched Thursday to the International Space Station on a chartered SpaceX flight.
The Falcon rocket blasted off from NASA's Kennedy Space Center in late afternoon, carrying the three men, all with military pilot experience and representing their homelands. Their escort on the trip: A retired NASA astronaut who now works for the company that arranged the private flight.

The first U.S. moon landing attempt in more than 50 years appeared to be doomed after a private company's spacecraft developed a "critical" fuel leak just hours after Monday's launch.
Pittsburgh-based Astrobotic Technology managed to orient its lander toward the sun so the solar panel could collect sunlight and charge its battery, as a special team assessed the status of what was termed "a failure in the propulsion system."

The first U.S. lunar lander in more than 50 years rocketed toward the moon Monday, launching private companies on a space race to make deliveries for NASA and other customers.
Astrobotic Technology's lander caught a ride on a brand new rocket, United Launch Alliance's Vulcan. The Vulcan streaked through the Florida predawn sky, putting the spacecraft on a roundabout route to the moon that should culminate with an attempted landing on Feb. 23.

Scientists anticipated the eruption of a volcano in southwestern Iceland for weeks, so when it happened on Monday night, it was no surprise. The region had been active for more than two years and thousands of small earthquakes rattled the area in recent weeks.
Here is a look at what happened and what may be ahead:
