In this decade, multiple space agencies and commercial space entities will be taking us back to the Moon. But unlike the Apollo Era, the goal of these programs is not “footprints and flags,” but to establish the necessary infrastructure to keep going back. In particular, NASA, the ESA, Roscosmos, and China are all planning on establishing outposts that will allow for scientific research and a sustained human presence.

The ESA is currently showcasing what its outpost will look like at the 17th annual Architecture Exhibition at the La Biennale di Venezia museum in Venice. It’s known as the International Moon Village, which was designed by the architecture firm Skidmore, Owings & Merrill (SOM) with technical support from the ESA. This same company recently unveiled a prototype of the skeletal metal component that will one day be part of the Village’s lunar habitats.

Conceptual Design for a Lunar Habitat

Between now and the end of this decade, multiple space agencies plan to send astronauts to the Moon for the first time since the Apollo Era. But whereas Apollo was a “footprints and flags” affair, the current proposals for lunar exploration call for the creation of infrastructure that allow for a sustained human presence there. In addition to NASA’s Artemis Program, the ESA is also working on a plan to create an “International Moon Village.”

For years, the ESA has released teasers as to what this “successor to the International Space Station” (ISS) might look like, the latest of which is on display at the La Biennale di Venezia museum in Venice. As part of the 17th International Architecture Exhibition, the architecture firm Skidmore, Owings & Merrill (SOM) showcased their design (with technical support from the ESA) for a semi-inflatable lunar habitat that could facilitate long-term lunar settlement.

Astronaut Pee Will Help Build Bases on the Moon

In the next few decades, NASA, the European Space Agency (ESA), China, and Russia all plan to create outposts on the lunar surface that will allow for a permanent human presence. These proposals seek to leverage advances in additive manufacturing (aka. 3-D printing) with In-Situ Resource Utilization (ISRU) to address the particular challenges of living and working on the Moon.

For the sake of their International Moon Village, the ESA has been experimenting with “lunacrete” – lunar regolith combined with a bonding agent to create a building material. But recently, a team of researchers conducted a study (in cooperation with the ESA) that found that lunacrete works even better if you add a special ingredient that the astronauts make all by themselves – urine!

ESA is Going to Test Two Rovers Working Together to Explore the Moon

The ESA has spent the past few years working towards the creation of an international lunar base, something that will serve as a spiritual successor to the International Space Station (ISS). To accomplish this, they have enlisted the help of other space agencies and contractors to develop concepts for space habitats and construction methods as well as ways to provide robotic and logistical support.

Recently, the ESA’s Technology Development Element (TDE) signed on with the French technology developer COMEX to create the TRAILER robotic system. This two-year project will test a new mission architecture where two rovers work in tandem (and with the help of astronauts) for the sake of exploring the lunar surface and building a permanent outpost on the Moon.

How Do We Settle on the Moon?

Welcome back to our series on Settling the Solar System! Today, we take a look at the closest celestial neighbor to Earth. That’s right, we’re taking a look at the Moon!

Chances are, we’ve all heard about it more than once in our lifetimes and even have some thoughts of our own on the subject. But for space agencies around the world, futurists, and private aerospace companies, the idea of colonizing the Moon is not a question of “if”, but “when” and “how”. For some, establishing a permanent human presence on the Moon is a matter of destiny while for others, it’s a matter of survival.

Not surprisingly, plans for establishing a human settlement predate both the Moon Landing and the Space Race. In the past few decades, many of these plansa have been dusted off and updated thanks to plans for a renewed era of lunar exploration. So what would it take to establish a permanent human presence on the Moon, when could it happen, and are we up to that challenge?
