If and when we ever get an asteroid mining industry off the ground, one of the most important decisions to be made in the structure of any asteroid mining mission would be how to get the resources back to where all of our other infrastructure is—somewhere around the Earth.

That decision typically will focus on one of two propulsion methodologies—chemical rockets, such as those we already use to get us into space in the first place, or solar sails, which, while slower and unable to get us into orbit, don't require any fuel. So which propulsion methodology is better for these future missions? A study by researchers at the University of Glasgow looked at those two scenarios and came out with a clear-cut answer—solar sails.

When answering these types of theoretical questions, it is essential to impose limits on the answers. For example, billions of asteroids exist in the solar system, so it's more realistic to only look at those known as near-Earth asteroids (NEAs).

The Orion space capsule from Artemis I has come full circle, having launched from Kennedy Space Center, traveled 1.4 million miles in space and around the moon, splashed back down to Earth in the Pacific Ocean, and now journeyed 2,500 miles over land for its return to Florida.

After Orion was recovered at sea on Dec. 11, it made its way to Naval Base San Diego before heading by truck to arrive at KSC on Dec. 30. It now sits at NASA's Multi Payload Processing Facility, still sealed tight from its celestial journey.

The passengers have been waiting patiently to get out of the capsule. Since they're just mannequins, though, they can wait a little longer.

The most human-looking of the three, named Commander Moonikin Campos in deference to the late Arturo Campos who helped NASA bring the Apollo 13 crew safely back to Earth, was joined by two partial-body mannequins named Zohar and Helga. Their presence will help NASA determine just what sort of radiation levels and other flight stresses humans will face during the first crewed flight of Orion on Artemis II.

If you lift your eyes to the sky Friday night, you can catch the first full moon of 2023—the wolf moon.

The full moon can best be seen at 6:08 p.m. EST on Friday and will appear full through Sunday morning, according to NASA.

"Look for the moon to rise from the northeastern horizon around sunset that evening," according to the Old Farmer's Almanac.

This is the first of 13 full moons in 2023, the Old Farmer's Almanac said.

The moon is also known as a micromoon, because the moon, which circles the Earth in an elliptical orbit, is farther from the Earth, said Space.com.

Why is it called the wolf moon?

The first full moon of the year is known as the wolf moon because historically it was believed during the winter wolves howled more at night because they were hungry, the Old Farmer's Almanac said.

The name has stuck even though there are doubts about the accuracy of the wolf moon moniker.

Why is it also called a micromoon?

For this full moon, the moon will be about 250,000 miles from Earth.

Final preparations were under way Monday for the first rocket launch from UK soil, catapulting it into the "exclusive" club of nine nations able to send crafts into Earth's orbit.

A repurposed Boeing 747 carrying the 70-foot (21-meter) rocket containing nine satellites will take off from a spaceport in Cornwall, southwest England, at 2216 GMT.

The rocket will detach from the aircraft at a height of 35,000 feet over the Atlantic Ocean to the south of Ireland before later discharging the satellites.

The aircraft will then return to Spaceport Cornwall, a consortium that includes Virgin Orbit and the UK Space Agency, at Cornwall Airport Newquay.

The launch will be the first from UK soil. UK-produced satellites have previously had to be sent into orbit via foreign spaceports.

"Joining that really exclusive club of launch nations is so important because it gives us our own access to space... that we've never had before here in the UK," Spaceport Cornwall chief Melissa Thorpe told BBC television on Monday.

Over 2,000 people are expected to watch the launch named "Start Me Up" after the Rolling Stones song.
