Take an Ultra-Detailed Tour of the Moon With This NASA Video

A new video will give you a tour of the Moon as you've never seen it, courtesy of NASA's Lunar Reconnaissance Orbiter. The 4K-resolution visualization posted by NASA's Goddard Space Flight Center, spotted over at CBS, was created using image data collected by the spacecraft since it began orbiting the Moon in 2009.

NASA narrates a guided tour that explores features like the Moon's South Pole, the famous Tycho Crater, the Aristarchus Plateau, and the Apollo 17 landing site in the Taurus-Littrow Valley.

The high resolution of the imagery allows you to clearly see things like the mysterious 328-foot-wide boulder on top of Tycho Crater's central peak and the Apollo 17 lunar lander and rover that still sit on the surface of the Moon.

The video explains the importance of the sites pictured and what the LRO data can tell us about the Moon's structure and characteristics, like how studying shadows on the Moon's North Pole can help us scope out sites for future solar power generators. Gravity measurements from the Orientale Basin may reveal the structure of the lunar crust there, and temperature readings and reflectance could alert us to potential water ice at the South Pole.

Take your own personal tour of the Moon in the video below.

NASA Has a Plan to Stop the Next Asteroid That Threatens Life on Earth

An asteroid colliding catastrophically with Earth within your lifetime is unlikely, but not out of the question. According to NASA, objects large enough to threaten civilization hit the planet once every few million years or so. Fortunately, NASA has a plan for dealing with the next big one when it does arrive, Forbes reports.

According to the National Near-Earth Object Preparedness Strategy and Action Plan [PDF] released by the White House on June 21, there are a few ways to handle an asteroid. The first is using a gravity tractor to pull it from its collision course. It may sound like something out of science fiction, but a gravity tractor would simply be a large spacecraft flying beside the asteroid and using its gravitational pull to nudge it one way or the other.

Another option would be to fly the spacecraft straight into the asteroid: The impact would hopefully be enough to alter the object's speed and trajectory. And if the asteroid is too massive to be stopped by a spacecraft, the final option is to go nuclear. A vehicle carrying a nuclear device would be launched at the space rock with the goal of either sending it in a different direction or breaking it up into smaller pieces.

Around 2021, NASA will test its plan to deflect an asteroid using a spacecraft, but even the most foolproof defense strategy will be worthless if we don’t see the asteroid coming. For that reason, the U.S. government will also be working on improving Near-Earth Object (NEO) detection, the technology NASA uses to track asteroids. About 1500 NEOs are already detected each year, and thankfully, most of them go completely unnoticed by the public.

Stephen Hawking’s Memorial Will Beam His Words Toward the Nearest Black Hole

An upcoming memorial for Stephen Hawking is going to be out of this world. The late physicist’s words, set to music, will be broadcast by satellite toward the nearest black hole during a June 15 service in the UK, the BBC reports.

During his lifetime, Hawking signed up to travel to space on Richard Branson’s Virgin Galactic spaceship, but he died before he ever got the chance. (He passed away in March.) Hawking’s daughter Lucy told the BBC that the memorial's musical tribute is a “beautiful and symbolic gesture that creates a link between our father's presence on this planet, his wish to go into space, and his explorations of the universe in his mind.” She described it as "a message of peace and hope, about unity and the need for us to live together in harmony on this planet."

Titled “The Stephen Hawking Tribute,” the music was written by Greek composer Vangelis, who created the scores for Blade Runner and Chariots of Fire. It will play while Hawking’s ashes are interred at Westminster Abbey, near where Isaac Newton and Charles Darwin are buried, according to Cambridge News. After the service, the piece will be beamed into space from the European Space Agency’s Cebreros Station in Spain. The target is a black hole called 1A 0620-00, “which lives in a binary system with a fairly ordinary orange dwarf star,” according to Lucy Hawking.

Hawking wasn't the first person to predict the existence of black holes (Albert Einstein's general theory of relativity accounted for them back in the early 1900s), but he spoke at length about them throughout his career and devised mathematical theorems that gave credence to their existence in the universe.

Actor Benedict Cumberbatch, a friend of the Hawking family who portrayed the late scientist in the BBC film Hawking, will speak at the service. In addition to Hawking's close friends and family, British astronaut Tim Peake and several local students with disabilities have also been invited to attend.
