You Can Now Get Your Own Copy of the Voyager 'Golden Record'

For more than 40 years, the spacecrafts Voyager 1 and Voyager 2 have taken the music, words, images, and sounds of Earth deeper into space thanks to the Golden Record, a copy of which was sent into space with each probe. This mix tape—a 12-inch, gold-plated copper disk—from us to the universe was famously put together by a team lead by Carl Sagan that was tasked with creating a snapshot of our world that aliens could understand—as long as they brought their own record player, as the probes, launched in 1977, lacked them.

Last year, a Kickstarter campaign offered a remastered, 40th-anniversary edition vinyl box set to project backers. The campaign aimed for $198,000; it raised $1,363,037. Now, anyone with $50 will be able to get a copy of Earth's interstellar playlist. You can now order the set from OZMA Records (via Light in the Attic Records). This is big: Even Sagan himself was turned down when he asked NASA for a copy.

The set includes a full-color hardcover book with two CDs of all the audio content and all the images that were encoded in analog on the record, scanned from a set of original slides. Science journalist Timothy Ferris, the original producer of the Voyager Interstellar Record, as it's officially called, penned an original essay for the book. Images beamed back to Earth from the Voyager probes are included too.

Among the tracks you'll hear are a Pygmy girls' initiation song from Zaire (now the Democratic Republic of the Congo), the Queen of the Night aria, no. 14, from Mozart's The Magic Flute, and the gospel blues song "Dark Was the Night" by Blind Willie Johnson. Sounds include volcanoes, laughter, footsteps, Morse code, wind, crickets, a tame dog, and a kiss between a mother and a child. Some of the images from 1977 depict a tropical island, a foot race, skyscrapers and mud-brick homes, and a trio of people licking, eating, and drinking.

"I remember sitting around the kitchen table making these huge decisions about what to put on and what to leave off," Ann Druyan, the creative director of the Golden Record and Sagan's wife, told NASA's ScienceCast. "We couldn't help but appreciate the enormous responsibility to create a cultural Noah's Ark with a shelf life of hundreds of millions of years."

Voyager 1 and Voyager 2 are now far from Earth: Voyager 2 on the periphery of our solar system in what's known as the heliosheath, and Voyager 1, far beyond it, 13 billion miles away—the most-distant object humans have ever sent into space. The probes still talk to us every day, sending back data. One day, perhaps, they'll talk to someone else Out There.

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.
