Solar Power in a Future Martian Lifestyle
An artist’s concept of a future biomanufacturing lab on Mars, powered by photovoltaic (solar power) technology. It will also synthesize food and medicines, and manufacture other needed materials, while recycling waste. (Credit: Davian Ho.)
Sometime in the next couple of decades, humans will head to Mars for long-term missions of more than 400 days. Such lengthy stays mean building Martian cities, complete with safe habitats, labs, and other infrastructure. Future Martians will have to do a lot to survive. They’ll build their cities, make their own food, distill water, create fuel, manufacture medicines, and create other supplies. To do that, they’ll use manufacturing facilities that they bring along. That all requires power. Lots of it. As we all know, Mars is noticeably lacking in obvious ways to make electricity. So, what will our intrepid explorers do to generate power for their new lives on the Red Planet?

Titan is an Alien World, but Surprisingly Familiar
Saturn’s largest moon, Titan, is a fascinating and mysterious world, a world literally shrouded in mystery due to thick clouds that cameras imaging in the visible spectrum cannot penetrate. This was made apparent when NASA’s Pioneer 11 became the first spacecraft to fly past Titan in 1979, and then NASA’s Voyager 1 and 2 in 1980 and 1981, respectively. All three spacecraft were equipped with cameras that were unable to penetrate Titan’s atmosphere of thick clouds, although atmospheric data from Voyager 1 suggested Titan might be the first body, aside from Earth, where liquid might exist on its surface.
A New Kind of Stellar Explosion Has Been Discovered: Micronovae
The most energetic explosions in the Universe come from stars called supernovae. These galactic bombs have the energy of about 1028 mega-tons. After they detonate, the only thing left behind is either a neutron star or black hole. Another type of stellar explosion is known as a nova which has much less energy and covers the surface of a white dwarf.
