MONTREAL, CANADA - Delaying NASA's next crewed moon mission was the right choice for risk, says one of the crew on board. Artemis 2 astronaut Jeremy Hansen, with the Canadian Space Agency (CSA), said he and his three NASA astronaut crewmates stand behind the agencies' decision to delay their round-the-moon mission at least nine months to September 2025.

Geminid meteors may be 10 times older than we thought

(NASA/JPL-Caltech/IPAC)

The rocks making up the Geminid meteor shower that occurs towards the end of every year may have been born through a chaotic event 18,000 years ago, a new study suggests -potentially making the meteoroids about 10 times older than previously estimated.

20 people in space! Humanity quietly tied a record

(NASA TV)

Not everyone will recognize the 20-person record, however, because Virgin Galactic flights get just 55 miles (88 kilometers) or so above Earth at their highest point. That's high enough to reach space according to NASA and the U.S. military, which set the boundary at 50 miles (80 km) up. But the international community generally goes with the "Kármán line," which lies at an altitude of 62 miles (100 km).

Sunspot 15 times wider than Earth is facing our way

(NASA/SDO and the AIA, EVE, and HMI science teams)

A sunspot so large it was seen from the surface of Mars is now facing Earth. The gargantuan sunspot group AR3576 from end to end stretches for more than 124,274 miles (200,000 kilometers) and contains at least four dark cores each larger than Earth, according to Spaceweather.com. It was imaged by NASA's Perseverance Rover from the surface of Mars just last week.

Here's what it's like taking a VR spacewalk

(Canadian Space Agency)

I, untrained as a spacewalking astronaut, felt literally lost in space as I fumbled around NASA's Gateway station circling the moon. I could see the Earth. Canadarm3 was doing its robotic arm thing right in front of me. I could even peek inside the empty crew modules.
