NASA reports that it’s got a robust sample from the surface of the asteroid Bennu. There is one snafu; gaps in the collecting lid is causing some loss of the pristine material.

This white paint could reduce the need for air conditioning
“We’re not moving heat from the surface to the atmosphere. We’re just dumping it all out into the universe, which is an infinite heat sink,” said Xiangyu Li, a postdoctoral researcher at the Massachusetts Institute of Technology who worked on this project as a Ph.D. student in Ruan’s lab.
WEST LAFAYETTE, Ind. — What if paint could cool off a building enough to not need air conditioning?
Purdue University engineers have created white paint that can keep surfaces up to 18 degrees Fahrenheit cooler than their ambient surroundings – almost like a refrigerator does, but without consuming energy.
According to the researchers, the paint would replace the need for air conditioning by absorbing nearly no solar energy and sending heat away from the building. Without the building heating up, air conditioning wouldn’t have to kick on.
Moment the Moon blocks NASA observation satellite’s view of the Sun during lunar transit
Astronomers observing Earth’s sun caught the moon photobombing their footage. The moon passed between NASA’s Solar Dynamics Observatory and the giant ball of gas during its lunar transit.
Incredible moment NASA’s OSIRIS-Rex makes touchdown on asteroid Bennu
On Wednesday NASA released incredible video and images showing the moment OSIRIS-REx touched down on the asteroid Bennu, more than 200 million miles away from Earth, Tuesday night.
Clues emerge about NASA’s ‘exciting’ Moon announcement
Nasa has provoked excitement across the world with the promise that it will reveal a “new discovery about the Moon” in a major announcement.
The space agency gave no details on what the announcement might be, apart from indicating that it “contributes to NASA’s efforts to learn about the Moon in support of deep space exploration” and had been made with Sofia, a converted Boeing 747 that works as a flying observatory.
But clues have begun to emerge about what the announcement could be about to reveal.
NASA Shares Photos from ‘Touch-and-Go’ with Asteroid Bennu 200 Million Miles Away
Photos of touching down on an asteroid.
On Tuesday, October 20th, NASA made history when the OSIRIS-REx mission successfully completed a “touch-and-go” sample collection maneuver with asteroid 101955 Bennu over 200 million miles away from Earth. And now, we have the timelapse to prove it.
NASA shared a total of 82 images from spacecraft’s SamCam imager covering the approach, the touchdown at sample sight Nightingale, and the “back-away burn.” The slideshow was captured over the course of approximately five minutes, and covers everything from about 82 feet (25 meters) above the asteroid, through the back-away burn, and up until the craft achieved an altitude of approximately 43 feet (13 meters), kicking up a lot of material along the way.
