Wind power will work on Mars, study finds
Posted by Klaus Baldauf in categories: energy, space
Wind power on Mars makes it possible for any rover or other craft to collect power at the poles or other areas on the planet that donât get constant sunlight.
NASA â National Aeronautics and Space Administration literally saved us from a planet-wide apocalypse.

NASA uses earth as laboratory to study distant worlds
Posted by Narendra Malewar in category: space
New study uses Earth as a stand-in for an exoplanet, and shows that even with very little light â as little as one pixel â it is still possible to measure key characteristics of distant worlds.

Could Electricity-Producing Bacteria Help Power Future Space Missions?
Posted by Klaus Baldauf in categories: biotech/medical, space
Humans arenât the only ones who have harnessed the power of electricity. Some bacteria do this, too, by producing structures that extend from their surface like wires to transfer electrons over distances. Now, scientists at NASAâs Ames Research Center in Californiaâs Silicon Valley are exploring this phenomenon to see if they can make use of these special microbes to perform essential functions on future space missions â from generating electricity to treating wastewater or producing medicines. With an experiment launching to the International Space Station, researchers will see whether the microbes work the same in space as they do on Earth.
To appreciate the rare abilities of the bacterium in question, called Shewanella oneidensis MR-1, you have to know what moving electrons around has to do with life. The transfer of electrons from one molecule to another is essential to all organisms, because it allows for the production of energy they need to survive. One reason that humans depend on oxygen is that this energy-producing chain reaction inside our cells is powered by transferring electrons to molecules of oxygen. The same goes for anything else that breathes oxygen, including Shewanella. But what makes this microorganism special is that it also has a back-up system that kicks in when the environment is low on oxygen. Shewanella keeps calm and carries on producing energy by using metals, like iron and manganese, instead.

The Quest to Find a Trillion-Dollar Nuclear Fuel on the Moon
Posted by Klaus Baldauf in categories: nuclear energy, space
Indiaâs space program wants to go where no nation has gone before -â to the south side of the moon. And once it gets there, it will study the potential for mining a source of waste-free nuclear energy that could be worth trillions of dollars.
