Yes, there will be macaroni and cheese on Mars
A team of scientists at Washington State University have developed a unique packaging method that effectively triples the shelf life of ready-to-eat macaroni and cheese. Now we know what’s on the menu for the Mars voyage. By our current best estimates, the trip to Mars will only take about seven to nine months. That’s not so bad, but the astronauts will likely want to return. And they also have to account for the fact that Earth and Mars have two different orbits. This means that the shortest route (per the Hohmann transfer plan) to Mars only happens once every 26 months. Astronauts could be looking at more than three years away from a habitable environment, a person tends to get hungry in that time. Hard Fork Summit is coming Join us in Amsterdam on October 15-17 Find out more Unfortunately, there aren’t that many food products cleared for space. For starters, NASA requires food have a shelf life of five years before it can be considered for the program. That … [Read more...] about Yes, there will be macaroni and cheese on Mars
New California lab seeks cure to deadly citrus disease
Amy Taxin, Associated Press Updated 5:22 pm CDT, Thursday, September 26, 2019 California citrus growers, packers and researchers gather for the opening of a new secure lab dedicated to the search for a cure for a deadly citrus-killing disease in Riverside, Calif., Thursday, Sept. 26, 2019. Growers hope the lab will speed up the search for a cure to the disease, which is spread by a tiny insect and has ravaged groves in Florida and abroad. The lab will be run through a partnership with University of California, Riverside. less California citrus growers, packers and researchers gather for the opening of a new secure lab dedicated to the search for a cure for a deadly citrus-killing disease in Riverside, Calif., Thursday, Sept. 26, ... more Photo: Amy Taxin, AP Photo: Amy Taxin, AP Image 1 of / … [Read more...] about New California lab seeks cure to deadly citrus disease
To find the best parking spot, do the math
The next time you're hunting for a parking spot, mathematics could help you identify the most efficient strategy, according to a recent paper in the Journal of Statistical Mechanics. It's basically an optimization problem: weighing different variables and crunching the numbers to find the optimal combination of those factors. In the case of where to put your car, the goal is to strike the optimal balance of parking close to the target—a building entrance, for example—without having to waste too much time circling the lot hunting for the closest space. Paul Krapivsky of Boston University and Sidney Redner of the Santa Fe Institute decided to build their analysis around an idealized parking lot with a single row (a semi-infinite line), and they focused on three basic parking strategies. A driver who employs a "meek" strategy will take the first available spot, preferring to park as quickly as possible even if there might be open spots closer to the entrance. A driver … [Read more...] about To find the best parking spot, do the math
Radar installed to better watch unstable Mont Blanc glacier
Colleen Barry and Charlene Pele, Associated Press Updated 12:44 pm CDT, Thursday, September 26, 2019 The Planpincieux glacier located in the Alps on the Grande Jorasses peak of the Mont Blanc massif, is seen from Val Ferret, a popular hiking area on the south side of the Mont Blanc, near Courmayeur, northern Italy, Wednesday, Sept. 25, 2019. Italian officials sounded an alarm Wednesday over climate change due to the threat that the fast-moving melting glacier is posing to the picturesque valley near the Alpine town of Courmayeur, the glacier, which spreads 1,327 square kilometers (512 square miles) across the mountain, has been moving up to 50 centimeters (nearly 20 inches) a day less The Planpincieux glacier located in the Alps on the Grande Jorasses peak of the Mont Blanc massif, is seen from Val Ferret, a popular hiking area on the south side of the Mont Blanc, near Courmayeur, northern ... more Photo: … [Read more...] about Radar installed to better watch unstable Mont Blanc glacier
