Tomorrow, one way or another, the ESA’s Rosetta mission is coming to an end. In a final maneuver, the craft will attempt to land on the surface of the comet, following in the footsteps of the Philae lander, though hopefully with more success. The video shows the final orbit plan, and really highlights how amazing mission scientists are to be able to plan a landing site when the comet is rotating so quickly, relative to the craft’s motion. You can follow the link to watch the live broadcast of the event here. The mission will end around 7:20am EST tomorrow,...
In the past year or so it’s been interesting to see space agencies and companies produce movie-type trailers for scientific expeditions. The technology is there, and it is a proven way to inspire the general public. It also creates an opportunity to create some of the amazing science being done, even if it’s just a small taste. Space X has been candid about wanting to colonize Mars, and yesterday they released a trailer to give some inspiration to all of us. It shows a system that utilizes their nearly-established system of landing and reusing rockets, as well as refueling in...
Here is a map of the nations of the world that use the two systems of measurement. Metric shown in blue and imperial shown in red. While it’s not always good to go with the crowd, there is a reason why more nations use the metric system. An often-cited passage from the book Wild Thing by Josh Bazell: “In metric, one milliliter of water occupies one cubic centimeter, weighs one gram, and requires one calorie of energy to heat up by one degree centigrade—which is 1 percent of the difference between its freezing point and its boiling point. An amount...
