We don’t fully know the answer. But every crew that resides on the International Space Station provides us information that we use to adjust our protocols and that extends that period of time. Let’s take a closer look.
Deep-space radiation is a serious but largely unquantified threat to astronauts making a long trip to Mars. A new study in mice is discouraging: Space-like levels of radiation exposure damaged their neurons, giving the mice cognitive problems.
NASA is taking the hunt for life on other worlds to the next level.
NASA’s Dawn spacecraft has spent a month in the shadow of Ceres. But now, the highest resolution images of the dwarf planet to date reveal its north pole.
Leaving the cozy confines of Earth’s atmosphere for life aboard the ISS is an exceedingly rare experience reserved for just a handful of astronauts. But thanks to NASA and GoPro, now you can share in the breathtaking views/sheer terror that astronaut Terry Virts enjoyed during a recent hour-long spacewalk.
Our sun has only been around for 4.5 billion years — which means it missed the cute early years of the Milky Way galaxy. If you were standing on a planet 10 billion years ago, when the Milky Way was relatively young, the night sky would have looked very different.
NASA is certain: We’re not alone in this universe.
Speaking at a public panel on Tuesday in Washington D.C., NASA scientists discussed the likelihood of finding organic life in our solar system. Given the surprising number of oceans residing throughout our celestial home, they say “it’s definitely not an if, it’s a when.”
