In Case You Missed It: Poop for the Ages

Back in July 2019, Vox had a great article about the waste astronauts left behind on the Moon. In the article, “Apollo Astronauts Left Their Poop on the Moon. We Gotta Go Back for That Shit.,” we learn about approximately 96 bags of human waste left behind on the moon. The topic is relevant today because (1) we are talking about returning to the Moon under the Artemis mission and (2) we probably want to learn more about the lifespan of this waste before we continue to deposit it on the Moon, Mars, and elsewhere. So maybe it is time to revisit the poop.

Earlier, The Atlantic had another article that listed much more human debris on the Moon than just the 96 bags (of urine, feces, and vomit, mind you). Here is the incomplete list:

  • more than 70 spacecraft, including rovers, modules, and crashed orbiters;
  • 5 American flags;
  • 2 golf balls;
  • 12 pairs of boots;
  • TV cameras;
  • film magazines;
  • 96 bags of urine, feces, and vomit;
  • numerous Hasselbad cameras and accessories;
  • several improvised javelins;
  • various hammers, tongs, rakes, and shovels;
  • backpacks;
  • insulating blankets;
  • utility towels;
  • used wet wipes;
  • personal hygiene kits;
  • empty packages of space food;
  • a photograph of Apollo 16 astronaut Charles Duke’s family;
  • a feather from Baggin, the Air Force Academy’s mascot falcon, used to conduct Apollo 15’s famous “hammer-feather drop” experiment;
  • a small aluminum sculpture, a tribute to the American and Soviet “fallen astronauts” who died in the space race—left by the crew of Apollo 15;
  • a patch from the never-launched Apollo 1 mission, which ended prematurely when flames engulfed the command module during a 1967 training exercise, killing three U.S. astronauts;
  • a small silicon disk bearing goodwill messages from 73 world leaders, and left on the moon by the crew of Apollo 11;
  • a silver pin, left by Apollo 12 astronaut Alan Bean;
  • a medal honoring Soviet cosmonauts Vladimir Komarov and Yuri Gagarin; and
  • a cast golden olive branch left by the crew of Apollo 11.

In the 2022 movie Moonshot, we sent Martian trash back to Earth. But that was not the case with the Moon. And now China and Russia are clamoring to do the same in the near future. Will the Moon someday be marked with more trash heaps than craters?

One might argue that explorers throughout time have had to leave something behind. Think of the piles of trash as well as corpses left on the top of Mount Everest. The great sea explorers also left plenty of men, material, and ships at the bottom of the sea where they would remain unclaimed.

But the interesting part of the Vox story is the potential of life remaining in that trash and even producing new life. If such biological material can seed new life, then who can say whether the Earth was simply a rest stop for aliens on their way somewhere else, and we are the product of their poop.

One more thing. If we do manage to let the Earth slip away from us and flip into another Venusian nightmare, the Moon poop may be the only human biology for a future alien to analyze. We sent the Voyager and other spacecraft out into the void with recordings and data, but no one thought about adding a biological component. Well, now we have that surviving piece on the Moon should it be needed. If we can figure out what a Tyrannosaurus was eating millions of years ago, maybe future visitors can figure out what the astronauts were eating in 20th century Texas.

Intense stuff, and worth reading about when you have a moment.

Space Stories: Chinese Lunar Nuclear Station, Helium Exoplanets, and the UAE Lunar Rover

Here are some recent stories of interest.

—Republic World: “China Plans Development Of New Nuclear System To Power Its Bases On Moon By 2028“

China is developing a nuclear system that will be used to power its lunar station planned to be developed on the Moon’s South Pole. Wu Weiren, chief designer of the Chinese lunar exploration programme, told Chinese broadcaster CCTV that this new system will fulfill the ‘high-power energy demands’ of the station, the South China Morning Post (SCMP) reported. Notably, the station is being developed by the China National Space Administration (CNSA) and the Russian space agency Roscosmos and is expected to complete by 2028.

—University of Chicago: “Many Planets Could Have Atmospheres Rich in Helium, Study Finds“

For centuries, no one knew if we were alone in the universe—or if there were even other planets like ours. But thanks to new telescopes and methods in the past decades, we now know there are thousands and thousands of planets out there circling faraway stars, and they come in all sorts of shapes and sizes—large and small, rocky and gaseous, cloudy or icy or wet. A study by scientists with the University of Chicago, the University of Michigan and the University of Maryland suggests another for the list: planets with helium atmospheres. Moreover, the discovery may suggest a new step in our understanding of planet evolution. Their simulations found that it’s likely that helium would build up in the atmospheres of certain types of exoplanets over time. If confirmed, this would explain a decades-long puzzle about the sizes of these exoplanets.

—Astronomy.com: “China and United Arab Emirates Plan Lunar Rover Mission“

The United Arab Emirates’ fledgling space program took another step forward last month, securing an agreement to collaborate on China’s planned Chang’e 7 lunar mission, set to land near the Moon’s south pole in 2026. The Mohammed bin Rashid Space Center (MBRSC) in Dubai will build a small robotic rover, which will hitch a ride on the Chang’e 7 lander, according to the agreement signed Sept. 16 between MBRSC and the China National Space Administration (CNSA).

Gift Ideas: Lego Lunar Research Base

While we await the Artemis III crew landing on the Moon and related lunar base, you might want to create your own mission with the Lego Lunar Research Base (shown above), which has “NASA-inspired” details. The playset has almost 800 Lego pieces, so you can build it yourself (to NASA specs, of course).

The playset comes with a “… lunar lander, VIPER rover and a domed accommodation module with laboratories, garage and air lock, plus 6 astronaut minifigures. I’m assuming the rocket that gets the astronaut minifigures to the Moon is sold separately.

And below is the Lego International Space Station is you are looking for something more traditional (and less expensive).

It’s great to see that Lego is allowing kids to build their own space missions at home.

Some of you may have played with Star Wars and Star Trek sets as kids, but at least these latest Lego set have a ring of credibility. Star Wars helped you destroy the galaxy, whereas Star Trek seemed more interest in exploration and at least had the veneer of Artemis CXXV.

I checked on whether Chinese and Russian kids with have their own space playsets and found the Russian Roscosmos Soyuz MS spacecraft (still a concept) and China’s Jiuquan Satellite Launch Center (made by a Lego copycat), both shown below.

The Jiuquan Satellite Launch Center playset comes with a Long March 2F rocket and an authentic warning sign stating, “Those stealing secrets will be caught, once they’re caught they will be killed [decapitated].”

Maybe even reality is not always the best model for play.

Extra: You can find more Lego space models at the NASA gift shop.

Space Mission: ESA’s Euclid Telescope

To follow up on the previous post, Russia also lost out on launching the European Space Agency’s (ESA) Euclid spacecraft. Russia was supposed to launch it on a Soyuz-ST/Fregat rocket this December, but the country’s invasion of Ukraine led to a change in plans. SpaceX will now be launching the spacecraft next year.

Euclid was designed to study dark energy and dark matter, and make a 3D-map of the Universe. The project includes scientists from 14 countries: Austria, Denmark, France, Finland, Germany, Italy, Netherlands, Norway, Spain, Switzerland, Portugal, Romania, the UK, and the US.

Euclid hopes to answer the following questions:

  • How did the Universe originate? What were the conditions just after the Big Bang, and how did these give rise to the large-scale structures we see today?
  • Why is the Universe expanding at an accelerating rate today?
  • Is dark energy – a term often used to signify the mysterious force behind this cosmic acceleration – real? If so, is it a constant energy density intrinsic to and spread throughout space, or a new force of nature that slowly evolves as the Universe expands?
  • What is the nature of dark matter, and how do neutrinos possibly contribute? Are there other as-yet-undetected massive particles in the Universe?

Once launched, Euclid will operate in the Sun-Earth Lagrange point 2 (L2), which is where the James Webb Space Telescope is located as well as ESA’s Gaia spacecraft. Gaia, launched in December 2013, is currently mapping the stars in the Milky Way galaxy. It seems L2 is the place to be.

NASA is contributing infrared flight detectors for one of Euclid’s two science instruments. You can read more about the NASA contribution here.

Has Russia Lost its Space Mojo?

Marina Koren’s article in The Atlantic, titled “The Russian Space Program Is Falling Back to Earth,” has plenty to say about the state of Russia’s space program. Her assessment is pretty bleak outside of the continued collaboration related to the International Space Station (ISS).

She notes:

Beyond the ISS, though, Russia’s space portfolio isn’t all that grandiose these days. Although cosmonauts fly into orbit regularly, Russia does not have a rover on the far side of the moon, as China has, or orbiters around Mars, as India and the United Arab Emirates have. It does not have a fleet of space telescopes like the U.S has. The Soviet Union was the first to send a human being to space, decades ago, and its early accomplishments are a distinct point of national pride. But the Russian space program has stalled for years, plagued by sparse budgets. And that was before Vladimir Putin’s onslaught on Ukraine: Some of the space plans the country still had in the works are falling apart. Now the Russian space effort may be more adrift than ever.

The Russian invasion of Ukraine may be the last straw. It led to the cancellation of various collaborative space projects with other nations. For instance, back in March the European Space Agency (ESA) was forced to suspend its joint ESA/Roscosmos ExoMars Rover mission to Mars.

China seems to be pulling ahead of Russia in the space race, with Russia taking a back seat on future projects, such as a Moon base or new space station. On the ground, Russia has shown it is not up to a war with Ukraine, making its role as a military power questionable. The article notes that Russia’s status as a space power is now also in question.

And shooting down another nation’s satellites will not be seen as a sign of strength in either the military or space arena.
