A Total Lunar Eclipse is Coming With a Flower Blood Moon – How to See the Night Sky Spectacle

in Astronomy 787 views

Night sky fans, on May 15-16 look up to see the blood-red spectacle that is a total lunar eclipse.

A lunar eclipse occurs when the full moon slips into the Earth’s shadow—and those watching from South America and the eastern side of North America are in for quite the show.

If you’re an eclipse hunter living in North America’s west, or in Africa or Europe – you’ll also get to experience real beauty in the shape of not a total, but a partial lunar eclipse.

Such an eclipse can be a wonder to see, as it gives viewers the chance to witness the Japanese Lantern Effect—according to Farmer’s Almanac, in such moments the surface of the moon appears the color of glowing copper, gradating down to a beautiful “uneclipsed yellow sliver.”

To get precise times for the eclipse spectacular where you are, TimeandDate.com has you covered. Of course, as this is a lunar rather than a solar eclipse, you don’t need to worry about damaging your eyes by looking up.

NASA Develops ‘Lunar Backpack’ to Aid New Moon Explorers

in Uncategorized 212 views

Imagine a mountaineering expedition in a wholly uncharted environment, where the hikers had the ability to generate a real-time 3D map of the terrain.

NASA researchers and their partners have developed a remote-sensing mapping system set to aid explorers in the most isolated wilderness imaginable: the airless wastes at the South Pole of the Moon.

The Kinematic Navigation and Cartography Knapsack (KNaCK) is a mobile lidar scanner—a remote sensing method that uses light detection and ranging laser light to measure range.

Donned like a hiker’s backpack, it makes use of an innovative type of lidar called frequency modulated continuous wave (FMCW) lidar in order to provide Doppler velocity and range for millions of measurement points per second. These measurement points instantly create a real-time navigation system, delivering to the explorer a 3D “point cloud” or high-resolution map of the surrounding terrain.

Think of it as a superpowered version of laser range finders used by surveyors or the highly sensitive proximity alarms that help smart cars avoid collisions, said planetary scientist Dr. Michael Zanetti, who leads the KNaCK project at NASA’s Marshall Space Flight Center in Huntsville, Alabama.

“Basically, the sensor is a surveying tool for both navigation and science mapping, able to create ultra-high-resolution 3D maps at centimeter-level precision and give them a rich scientific context,” Zanetti said. “It also will help ensure the safety of astronauts and rover vehicles in a GPS-denied environment such as the Moon, identifying actual distances to far-off landmarks and showing explorers in real time how far they’ve come and how far is left to go to reach their destination.”

Probing shadow lands

That’s a key challenge as Artemis-era explorers prepare to undertake the first modern missions to the Moon, and the first ever to its South Pole. The Sun never rises more than 3 degrees above the lunar horizon there, leaving much of the terrain in deep shadow. That makes distances to various points of interest difficult to eyeball.

Initiated in 2020 with funding by NASA’s Early Career Initiative, the KNaCK project has partnered with Torch Technologies Inc. of Huntsville to develop the backpack prototype and associated navigation algorithms that permit accurate mapping without GPS.

Using KNaCK during rover excursions and when traveling on foot, explorers could precisely map the topography of the landscape, including deep ravines, mountains, and caves. Lidar even works in pitch blackness, relieving astronauts of the need to haul cumbersome lighting rigs everywhere they go.
