Travellers to Mars Need to Avoid the Dust
Many health problems are faced by astronauts who spend significant amounts of time in space. But perhaps one of the most insidious is the danger to their mental health. In particular, a prolonged sense of loneliness that could crop up as part of a long-term deep space mission could have dire consequences. A recent paper from Matthieu Guitton, the editor-in-chief of the journal Computers in Human Behavior: Artificial Humans and a researcher at the CERVO Brain Research Center in Quebec, proposes one potential solution to that risk - social robots.
One of the common misconceptions about black holes is that they devour not only matter, but also the history of that matter. So when a black hole forms, you can only guess how it came to be. That isn't entirely true. Informational history is only lost when matter crosses the event horizon, and perhaps not even then. The material surrounding a black hole still has a rich history. In a recent study, astronomers have used that history to uncover the origins of a black hole system.
All of the ways you've heard that deep space wants to kill us — and how plausible or likely each scenario is.

The post The tragic termination of the Diabetes Prevention Program Outcomes Study first appeared on Science-Based Medicine.Could microbes survive in the permanently shadowed regions (PSRs) of the Moon? This is what a recent study presented at the 56th Lunar and Planetary Science Conference hopes to address as a team of researchers from the United States and Canada investigated the likelihood of long-term survival for microbes in the PSR areas of the Moon, which are craters located at the poles that don’t see sunlight due to the Moon’s small axial tilt. This study has the potential to help researchers better understand unlikely locations where they could find life as we know it throughout the solar system.
What can a sample return mission from Jupiter’s volcanic moon, Io, teach scientists about planetary and satellite (moon) formation and evolution? This is what a recent study presented at the 56th Lunar and Planetary Science Conference hopes to address as an international team of more than two dozen scientists discussed the benefits and challenges of a mission to Io with the goal of sampling its volcanic plumes that eject from its surface on a regular basis.
It’s getting a little harder to be the first humans to achieve something but, if all goes to plan, a team of four private astronauts are expected to head off into a polar orbit around Earth aboard the SpaceX Dragon capsule today (31 March) at 9:46pm ET and take the crew over the North and South Poles of Earth. Financed by Chun Wang, a Malta-based investor, they are planning a series of experiments, including attempting to grow oyster mushrooms in microgravity, which could eventually become a source of food for space missions.
Astronomers suspect that Europa has cryovolcanoes, regions where briny water could erupt through Europa's ice shell, throwing water—and hopefully organic molecules—into space. NASA's Europa Clipper and ESA's JUICE mission are on their way and will be able to scan the surface of the icy moon for signs of cryovolcanism. What should they be looking for? Pockets of brine just below the surface could be active for 60,000 years and should be warmer than their surroundings.
