The Washington Monument Is Transforming Into a Full-Scale Saturn V Rocket for the 50th Anniversary of the Apollo 11 Moon Landing

Where better to celebrate the 50th anniversary of the first Moon landing than in front of a revered national monument that also happens to resemble a giant rocket?

Next week, DCist reports, the Smithsonian National Air and Space Museum will project an image of the 363-foot-tall Saturn V rocket that launched Buzz Aldrin, Neil Armstrong, and Michael Collins into space on July 16, 1969, onto the 555-foot-tall Washington Monument. Underneath the monument, flanked by screens playing a 17-minute program about the Moon landing, will be a 40-foot-wide replica of the iconic Kennedy Space Center countdown clock that NASA has called “one of the most-watched timepieces in the world.”

Projecting an image onto an irregular object is a little more complicated than doing so on a run-of-the-mill, rectangular movie screen. The process is called projection mapping, which uses augmented reality to conform the projection to the object, making it seem like the projection is actually just part of the object. 59 Productions, the company behind this program, also created the video design for London’s 2012 Olympic Games opening ceremony and won a 2015 Tony Award for the video design of Christopher Wheeldon’s stage revival of An American in Paris.

So who exactly has to approve transforming one of our nation’s most famous monuments into a really tall, skinny optical illusion? In this case, the House of Representatives, the Senate, the secretary of the interior, and the president himself. Both houses of Congress unanimously passed the bipartisan resolution, H.J. Res. 60 [PDF], in mid-June, and the president signed it on July 5.

According to Ellen Stofan, director of the Smithsonian National Air and Space Museum, the larger-than-life nature of the setting befits the occasion. “The Washington Monument is a symbol of our collective national achievements and what we can and will achieve in the future,” she told DCist. “It took 400,000 people from across the 50 states to make Apollo a reality. This program celebrates them, and we hope it inspires generations too young to have experienced Apollo firsthand to define their own moonshot.”

You can see the Saturn V projection from 9:30 p.m. to 11:30 p.m. on July 16, 17, and 18. The best view is on the National Mall in front of the Smithsonian Institution Building (also known as the “Castle”) between 9th and 12th streets. The entire program, titled “Apollo 50: Go for the Moon,” will run at 9:30 p.m., 10:30 p.m., and 11:30 p.m. on Friday, July 19, and Saturday, July 20.

A Super Pink Moon—the Biggest Supermoon of 2020—Is Coming In April

The sky has already given us several spectacular reasons to look up this year. In addition to a few beautiful full moons, we’ve also gotten opportunities to see the moon share a “kiss” with Venus and even make Mars briefly disappear.

In early April, avid sky-gazers are in for another treat—a super pink moon, the biggest supermoon of 2020. This full moon is considered a supermoon because it coincides with the moon’s perigee, or the point in the moon’s monthly orbit when it’s closest to Earth. According to EarthSky, the lunar perigee occurs on April 7 at 2:08 p.m. EST, and the peak of the full moon follows just hours later, at 10:35 p.m. EST.

How a supermoon is different.

Since the super pink moon will be closer to Earth than any other full moon this year, it will be 2020’s biggest and brightest. It’s also the second of three consecutive supermoons, sandwiched between March’s worm moon and May’s flower moon. Because supermoons only appear about 7 percent bigger and 15 percent brighter than regular full moons, you might not notice a huge difference—but even the most ordinary full moon is pretty breathtaking, so the super pink moon is worth an upward glance when night falls on April 7.

The meaning of pink moon.

Despite its name, the super pink moon will still shine with a normal golden-white glow. As The Old Farmer’s Almanac explains, April’s full moon derives its misleading moniker from an eastern North American wildflower called Phlox subulata, or moss pink, that usually blooms in early April. It’s also called the paschal moon, since its timing helps the Catholic Church set the date for Easter (the word paschal means “of or relating to Easter”).

Are Any of the Scientific Instruments Left on the Moon By the Apollo Astronauts Still Functional?

C Stuart Hardwick:

The retroreflectors left as part of the Apollo Lunar Ranging Experiment are still fully functional, though their reflective efficiency has diminished over the years.

This deterioration is actually now delivering valuable data. The deterioration has multiple causes including micrometeorite impacts and dust deposition on the reflector surface, and chemical degradation of the mirror surface on the underside—among other things.

As technology has advanced, ground station sensitivity has been repeatedly upgraded faster than the reflectors have deteriorated. As a result, measurements have gotten better, not worse, and measurements of the degradation itself have, among other things, lent support to the idea that static electric charge gives the moon an ephemeral periodic near-surface pseudo-atmosphere of electrically levitating dust.

No other Apollo experiments on the moon remain functional. All the missions except the first included experiment packages powered by radiothermoelectric generators (RTGs), which operated until they were ordered to shut down on September 30, 1977. This was done to save money, but also because by then the RTGs could no longer power the transmitters or any instruments, and the control room used to maintain contact was needed for other purposes.

Because of fears that some problem might force Apollo 11 to abort back to orbit soon after landing, Apollo 11 deployed a simplified experiment package including a solar-powered seismometer which failed after 21 days.
