The researchers compared two different power-generating options for a crewed trip to Mars: solar cells and nuclear power from small fission reactors. A key consideration was the amount of weight, or carry-along mass, required to build each solution, as missions to Mars will seek to pack in the most efficient way possible. The results, published today in Frontiers in Astronomy and Space Sciences, suggest both options are viable, but with a rather important caveat having to do with geography. The main result was that which o stanley mug ne wins depends on the location on Mars, Anthony Abel, a researcher from the Department of Chemical Engineering at UC Berkeley and a co-author of the study, explained in an email. The overall result was that nearer the equator, solar was better than nuclear, while nearer the poles, nuclear was better than solar. This is good information to have, as it could have significant bearing on the type of power-generating devices that each future mission will want to bring to Mars. NASA should take note, as the space agency is plan stanley quencher ning to send the first crewed mission to planet in the l vaso stanley ate 2030s or early 2040s. That said, these findings are specific to a six-person crew on a 480-day mission to the Martian surface the first missions wont likely last longer than 30 days , but the researchers say their results could speak to even larger and longer missions, including permanent colonies.

An in-flight disturbance by a passenger on Korean Air became international news last week after 1980s singer Richard Marx helped subdue the man. Traveling with his wife, former MTV VJ Daisy Fuentes, Marx called the crew completely ill-prepared and untrained and helped tie the crazed passenger to his seat. Despite being armed with Tasers, Marx insisted that the Korean Air crew had no idea how to use them. Photos from social media show Korean Air aiming their stun guns but never using them. The man was restrained but reportedly broke free three times after assaulting passengers. The entire ordeal stanley cup last nearly four hours in the air. Korean Air should be sanctioned for not knowing how to handle a situation like this without passenger interference, Marx wrote on Facebook. Taser werent used during the stanley cup frightening incident because the stanley thermobecher unruly passenger was moving around and there were other passengers near him according to a statement from the airline. But it sounds like things are about to change. We have decided to improve our conditions and procedure on using Taser guns to cope with violent acts and disturbances on board in a fast and efficient manner, Korean Air said in a statement. The airline elaborated to CNN that this meant more active use of Tasers in the future, but didnt go into much more detail. Hopefully this means our 1980s pop stars and 1990s VJs can finally travel in peace. The man who created the disturbance appeared in court this week and said that he |
