Are chemical rockets or solar sails better to return resources from asteroids?

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).
Orion back at Kennedy Space Center so NASA can dissect Artemis I mission

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.
