Astronauts exploring the Moon will need all the help they can get, and scientists have spent lots of time and plenty of money coming up with different systems to do so. Two of the critical needs of any long-term lunar mission are food and oxygen, both of which are expensive to ship to the Moon from Earth. So, a research team from the Technical University of Munich spent some of their time analyzing the effectiveness of using local lunar resources to build a photobioreactor (PBR), the results of which were recently published in a paper in Acta Astronautica.

You can design the wheels for NASA's next moon vehicle with the 'Rock and Roll Challenge
NASA is calling on the public to help shape the future of lunar exploration by designing the next generation of wheels capable of navigating the moon's harsh terrain.
Simulating Ice Worlds in the Lab
What do extreme icy moons in the Solar System and unruly water behavior have to do with each other? That's what scientists at University of Sheffield in England wanted to know. So, they simulated conditions at Europa and Enceladus in the lab. Europa orbits Jupiter and Enceladus circles Saturn. Both have frozen surfaces and internal oceans of salty water. That water plays a huge role in resurfacing and reshaping these icy moons. That process is called cryovolcanism and it shows that water behaves much differently "out there" than it does here on Earth, where it freezes below 0 C and boils above 100 C.

Modeling Planet Formation With Water Tornadoes
Sometimes the easiest way to understand the physics of a phenomenon is to make a physical model of it. But how do you make a model of a system as large as, say, a protoplanetary disc? One technique, suggested in a recent paper in the Monthly Notices of the Royal Astronomical Society Letters by researchers at the Max Planck Institute for Astrophysics and the University of Greifswald, would be familiar to any grade schooler who took a science class - spin water around in a circle really fast.
Mysterious boost to Earth's spin will make Aug. 5 one of the shortest days on record
A strange shift in Earth's rotation is making our days milliseconds shorter — and scientists are racing to understand why.
Training robots from space

This summer, a team of robots explored a simulated martian landscape in Germany, remotely guided by an astronaut aboard the International Space Station. This marked the fourth and final session of the Surface Avatar experiment, a collaboration between ESA and the German Aerospace Center (DLR) to develop how astronauts can control robotic teams to perform complex tasks on the Moon and Mars.
