Solar cells made of moon dust could power future space exploration
The same dirt that clings to astronauts’ boots may one day keep their lights on. In a study published in Device, researchers created solar cells made out of simulated moon dust. The cells convert sunlight into energy efficiently, withstand radiation damage, and mitigate the need for transporting heavy materials into space, offering a potential solution to one of space exploration’s biggest challenges: reliable energy sources.
Moon dust may help astronauts power sustainable lunar cities. Here’s how.
Constructing solar arrays out of moon dust would reduce launch costs and make lunar bases more plausible, according to a new study. Continue ReadingMoon dust may help astronauts power sustainable lunar cities. Here’s how.
Megaroc: The British manned space program that almost was
As World War II drew to a close, the Allies were eager to get their hands on one of the most technologically amazing yet terrifying weapons in Nazi Germany’s armamentarium: the V-2 rocket. A long-range, liquid-fueled supersonic guided missile, the V-2 could carry a 2,000-pound (910 kilograms) warhead a staggering 200 miles (320 kilometers) fromContinue reading “Megaroc: The British manned space program that almost was” The post Megaroc: The British manned space program that almost was appeared first on Astronomy Magazine.
