Celebrating 60 Years of NASA, Where Art and Science Meet

To have a good time NASA’s sixtieth anniversary this yr, the company partnered with the Nationwide Symphony Orchestra to current a live performance in Washington entitled “NSO Pops: Area, the Subsequent Frontier.” NASA mission photos complemented performances of space-inspired music within the Kennedy Heart’s live performance corridor, together with Claude Debussy’s “Clair de Lune” (“Moonlight”), with a video of the Moon created by NASA science visualizer Ernie Wright.

At NASA’s Goddard Area Flight Heart in Greenbelt, Maryland, Wright works within the Scientific Visualization Studio, utilizing NASA knowledge to create correct visuals of celestial our bodies. Wright made the lunar imagery accompanying “Clair de Lune” with knowledge from the Lunar Reconnaissance Orbiter (LRO).

Since its 2009 launch, LRO has harvested knowledge on the Moon’s radiation, chemistry, temperature and topography. The form of the lunar terrain is measured by LRO’s laser altimeter, LOLA (Lunar Orbiter Laser Altimeter). “The precept behind measuring the topography of the Moon is pretty simple,” stated Noah Petro, LRO venture scientist. “We hearth a laser from the spacecraft to the floor of the Moon, and measure the time it takes that pulse to go from spacecraft to floor and again.”

The longer the laser takes to bounce again to LRO, the farther away the lunar floor. Over a few years, a topographic map of the complete Moon is constructed up, creating essentially the most correct map of a celestial physique’s topography ever created. Wright then makes use of this map and photos of the Moon in the identical 3D visualization software program most well-liked by animators equivalent to these at Pixar to make digital fashions. “What Ernie has finished is that he drapes the pictures on high of the topography,” Petro stated.

Topography was Wright’s largest problem. “The factor concerning the Moon is that the shadows are every little thing. For those who don’t do this effectively, you’ve just about misplaced the sport — there aren’t vibrant colours like on the Earth or Jupiter or Saturn,” Wright stated.

Wright’s video shows breathtaking views of lunar landmarks, starting with a dawn dragging shadows throughout the floor and ending with sunsets lengthening the darkness alongside the identical geography. The music, Wright stated, is “melancholy, solitary and contemplative, as should you’re alone, strolling by way of a backyard within the moonlight.” The consequence, with serene music that breathes in time with crisp visuals, is a perspective on our Moon that Debussy may have solely dreamed of when he tried to seize the essence of the physique that dominates the evening sky.

About Ernie Wright

Names of lunar landmarks are calmly penciled on one of Wright’s paper sheet music copies of “Clair de Lune” (or “Clair,” as he refers to it). Wright comes from a musical household, however he swears the reward handed him over. “I can barely learn music,” Wright stated, laughing. “And it wasn’t till I had listened to ‘Clair’ a couple of instances earlier than I assumed, ‘Oh, I can observe that.’”

Wright’s job exists on the confluence of laborious knowledge and pure magnificence. His formal background is in laptop science, and he has his personal yard telescope. “I have a look at stuff, I learn Sky & Telescope journal,” he stated.

For the previous 10 years at Goddard, nevertheless, data of astronomy and planetary and Earth sciences has turn into essential for Wright. Communication with scientists is an integral half of the work being finished by these within the Scientific Visualization Studio at Goddard.

“We now have to talk to the scientists credibly and perceive what they’re saying,” Wright stated. “We have to attain as much as their stage of understanding and pull down what we have to convey to different folks.”

Wright makes a speciality of using knowledge from NASA missions, equivalent to LRO, and representing them visually. A lot of the work he does lies in group of the info in order that it may be understood by the 3D animation software program he makes use of.

Wade Sisler, govt producer in Goddard’s Workplace of Communications, got here to Wright with the proposal that visuals accompany the music for “Clair de Lune.” “Ernie’s work was legendary at NASA,” Sisler stated. Wright had additionally crafted lunar visualizations for what can be Goddard’s viral “Tour of the Moon in 4K” video, so Sisler stated that asking Wright to assist “simply appeared pure.” The video grew to become “a shifting Ansel Adams portrait. The richness of the tones and the dynamic vary within the scenes made it so lovely and so totally different,” Sisler stated.

Wright’s work isn’t restricted to pleasing visible shows. Ten years in the past, one of Wright’s first initiatives at NASA concerned the seek for lunar water. LRO’s sister mission, the Lunar Crater Statement and Sensing Satellite tv for pc (LCROSS), was a spacecraft designed to collide with the Moon. The impression needed to be seen by way of Earth-based telescopes: astronomers would analyze the emitted mild to search for the presence of water. Wright was known as upon to assist the observatories by visualizing potential impression websites, particularly in shadowed areas the place water ice could possibly be discovered.

“They have been making this choice as they have been flying to the Moon,” Wright stated. “They have been relying rather a lot on LRO’s preliminary knowledge to information them to the perfect location. I used to be in a position to make use of that knowledge to render the shadows at their candidate websites, and that performed a job of their choice.”

Wright’s work, used for each artistry and analysis, is important to enhance our understanding of the Moon. There’s an inescapable distinction between his cutting-edge methodology and the primordial nature of the 4.5 billion-year-old celestial physique pictured. The Moon conjures up tributes by these equivalent to Claude Debussy and Ernie Wright, which in flip spark the creativeness of these their works attain.
