Exercise Keeps Astronaut Hearts in Fighting Shape for the Journey to Mars (opens the original)
Read excerpt
Getting a human body to Mars will take a toll on it. NASA and other space agencies have been concerned for years that the 6-9 month travel time to get to the Red Planet could have such a deleterious impact on human anatomy that any crewed mission would fail before it even began. But a new study, co-led by Dr. Benjamin Levine of the University of Texas Southwestern Medical Center and published in the journal Circulation, eases some of that concern by claiming that, given a sufficient exercise reg
Older Alien Worlds Might Still Be Stuck in the Slime Age (opens the original)
Read excerpt
There’s an active debate in the astrobiology community of where to use our best telescopes to look for our best chance of seeing alien life. That debate has been going on for decades, and will continue for some time to come, but now there’s another option up for consideration. A new paper in the International Journal of Astrobiology by Dr. Christopher Doughty of Northern Arizona University talks about how the total amount of carbon a planet is able to bring into the service of biology is a good
ESA And JAXA's Planetary Defense Mission Powers On For The First Time (opens the original)
Read excerpt
There’s a once-in-a-millennia astronomical opportunity coming up in about three years, and space agencies are rushing to make sure they’re ready for it. On Friday April 13th, 2029, the asteroid 99942 Apophis will fly within 32,000km of the Earth’s surface. The cruise liner sized piece of rock won’t hit us, but it should put on a great show, and, given the date it will pass by, is sure to cause panic amongst some parts of western civilization. One of the missions planned to watch this historic ev
Why the World’s Biggest Radio Telescope Had to Tweak Nature’s Perfect Sunflower Spiral (opens the original)
Read excerpt
Scientists love taking inspiration from nature. The evolutionary processes that have created such a diverse panoply of life on Earth can be a great source of ideas in solving technical problems. One such example is the pattern of sunflower seeds - they are arranged in a mathematically optimized pattern known as a Vogel spiral, and the international team building the Square Kilometer Array (SKA) in Australia decided to lay out their antennas in a similar pattern. But, as they report in a paper re
A 1,000°C Lunar Microreactor Could Power the Next Era of Moon Bases (opens the original)
Read excerpt
As humanity continues to move towards a permanent settlement on the Moon, we still have at least one big hurdle to face - the lunar night, which lasts for roughly fourteen days straight and can drop temperatures to a bone-chilling -223°C. In order to survive those conditions, we need a power source that doesn’t come and go with the Sun, or rely on non-existent stock of coal, gas or wind. In other words, we need nuclear power, and a new paper, available in pre-print on arXiv by Julius Mercz of th
