Just lately, NASA established potential touchdown websites close to the south pole of the moon for upcoming crewed missions of its Artemis program. However how will astronauts survive and thrive within the harsh lunar atmosphere?
One new proposal may assist them accomplish that. The Austrian firm PneumoCell (opens in new tab) has developed the PneumoPlanet inflatable habitat idea for the moon, which may include as much as 16 greenhouses and home as much as 32 astronauts.
“PneumoPlanet is an ultra-light inflatable construction coated by regolith that can function self-sufficiently by producing and recycling its personal oxygen and meals utilizing solar energy,” Philipp Gläser, a postdoctoral researcher on the Berlin Technical College and a co-author on a examine outlining the PneumoPlanet idea, advised House.com in an electronic mail.

“It could due to this fact function a everlasting lunar outpost enabling varied future missions to make use of it as a base,” Gläser added. “The habitat protects in opposition to cosmic radiation and micrometeorites, conserving the crew protected and permitting for longer mission durations.”
PneumoPlanet has acquired funding from the European Space Agency. The brand new examine suggests the habitat be situated close to one of many lunar poles, the place daylight is extra plentiful given the moon’s extraordinarily slight axial tilt. Ideally, PneumoPlanet could be arrange near a “completely shadowed area” (PSR), a polar crater ground that has been in darkness for eons and due to this fact may harbor giant quantities of water ice.
The architect and lead designer of PneumoPlanet is Thomas Herzig, who can also be the founder and CEO of PneumoCell. Herzig stated he is captivated with PneumoPlanet and its potential for helping future lunar astronauts, stressing that no different habitat idea gives what PneumoPlanet can when it comes to the general design, particularly pertaining to the greenhouse.
“All the hassle and power for 3D printing of huge partitions and ceilings shouldn’t be obligatory,” Herzig advised House.com in an electronic mail. “Crucial innovation lies within the mirrors that mirror the seen daylight in an optimum wavelength vary right into a greenhouse, whereas all of the dangerous particle radiation is saved out. Inside that greenhouse, we will self-sufficiently produce oxygen and meals in a pure manner from pure daylight solely, and the greenhouse is also a pure residing space for the crew.”
As Herzig states in a promotional video (opens in new tab), PneumoPlanet’smirrors will likely be hoisted with carbon fiber tubes on a rotating magnetic ring that can observe the course of daylight. This may permit pure daylight to go by a clear foil and enter the greenhouses with 65 kilowatts of power, which is equal to 265 watts per sq. meter — supreme for photosynthesis to happen, Herzig stated. With people scheduled to return to the lunar floor within the subsequent few years with the Artemis missions, may PneumoPlanet be a viable instrument for his or her habitat?
“Whereas a number of good renderings of moon habitats have been launched to draw the eye of the general public, till now, no everlasting and sustainable moon base is a part of the deliberate Artemis mission[s],” Herzig stated.
He described the present big-picture plan for Artemis, which includes constructing a small moon-orbiting space station referred to as Lunar Gateway to ship astronauts to the floor and having them sleep in a rover there for a number of days. Nevertheless, NASA has outlined plans to ascertain some infrastructure doubtlessly close to PSRs on the lunar floor, together with a four-person habitat, as a part of its Artemis Base Camp outpost. Herzig additionally famous that the Gateway won’t have the identical advantages of safety from cosmic radiation because the Worldwide House Station, because the latter orbits inside Earth’s magnetic discipline.
“I feel it’s a pity to place all that effort right into a lunar space station, as a substitute of constructing one thing on the moon, the place you should use the assets of the moon, present higher security and luxury for the crew and conduct experiments and industrial processes on the moon,” Herzig stated. “However because the Artemis mission has been delayed so many occasions, possibly NASA will change their thoughts about Lunar Gateway and a everlasting moon base in future.”
The venture is described in a paper (opens in new tab) revealed in December 2022 within the journal Planetary and House Science. Extra particulars might be discovered at PneumoCell’s website (opens in new tab).
