Pollution isn’t just Earth’s problem anymore. Despite not having established a permanent lunar residency, humans have already managed to dump 400,000 pounds of trash on the Moon . Much of this debris has been left behind over the twelve trips by humans to the lunar surface. Earthbound scientists figured out long ago that bringing the lunar visitors home would be cheaper and simpler if as much equipment as possible were left behind. Add in debris accumulated over unmanned missions and we have ourselves something of a lunar junkyard orbiting overhead. It’s important to remember that the trash we have left behind on the Moon does not exist in a vacuum. There is an enormous amount of space waste floating around our planet. Over 21,000 pieces of trash, from spacecraft fragments to disabled satellites, orbit the Earth. Most of the Moon’s trash was the result of crashed spacecraft , of which there are over 70. The remainder of the debris is a mish-mash oddly documenting humanity’s short lunar tenure. Because it is easier to return to Earth with as little weight as possible, each moon landing has permanently dropped a 22,700-pound Lunar Lander on the surface, as well as other modules, craft, or miscellaneous materials associated with that particular mission. Waste from low-gravity golf games as well as literal human waste (all 96 bags of it) litter the Moon’s face.

A small aluminum memorial left by the crew of Apollo 15 to honor fallen astronauts stands on the silent lunar landscape. The feather dropped in Apollo 15’s “hammer-feather drop” experiment also remains. Even though the Apollo 1 mission never made it to the Moon, as it was shut down prematurely after three astronauts were killed during a training exercise, a patch from the unlaunched mission found its way to the lunar surface too.

Saturn’s biggest moon has enough energy to power a US-sized space colony

Feeling like you’ve had enough of this planet? Saturn’s biggest moon , Titan, is an attractive option for a space colony, according to new research. Amanda Hendrix of the Planetary Science Institute and Yuk Yung of the California Institute of Technology (Caltech) say the moon has enough energy sources to power a settlement the size of the United States. Saturn is home to 53 moons. But Titan, the largest, possesses its own atmosphere , which according to NASA is rare for a moon. It turns out Titan could also have an abundance of energy sources, according to Hendrix and Yung. They say there are options for solar power , wind power , hydropower , and nuclear power on the moon. They drew on the information we know about Titan and mathematics based on technologies we currently have on Earth.

Tidal power could also potentially energize some of the colony as experts have observed strong tides on the moon. In particular, an area called the Throat of Kraken, which John Hopkins University planetary scientist Ralph Lorenz likened to the Strait of Gibraltar, could be the perfect location for a settlement. Lorenz, who was not involved with the research, told New Scientist, “We’re pretty sure there’s a very strong flow of liquid back and forth every Titan day. If you want reliable power that you know is going to be accessible, that’s where I would go.” Hendrix and Yung did say they overlooked some details, because there’s still a lot we don’t know about Titan, but view their research as a first step. Their study was published in the Journal of Astrobiology and Outreach this week. Via ScienceAlert Images via Wikimedia Commons and NASA/JPL-Caltech/USGS
