NASA's Next Mars Rover May Have Flying Sidekick NASA is considering sending a miniature helicopter to Mars to serve as an aerial scout for its Mars 2020 rover. The helicopter, which is intended primarily as a technology demonstrator, would be the first vehicle to traverse through the thin Martian atmosphere. Flying on Mars is a challenge. The planet's atmospheric pressure is just one percent that of Earth's so the aircraft needs relatively big blades compared to the size of its body. RELATED: Drone Invasion: A New Way to Explore Mars "The way any of these helicopters work is the rotor blades spin up and they produce lift because of the density of the atmosphere. The Crisis in Higher Education A hundred years ago, higher education seemed on the verge of a technological revolution. The spread of a powerful new communication network—the modern postal system—had made it possible for universities to distribute their lessons beyond the bounds of their campuses. Anyone with a mailbox could enroll in a class. Frederick Jackson Turner, the famed University of Wisconsin historian, wrote that the “machinery” of distance learning would carry “irrigating streams of education into the arid regions” of the country. Sensing a historic opportunity to reach new students and garner new revenues, schools rushed to set up correspondence divisions.
What is the theory that underpins <em>our</em> moocs? If you’re even casually aware of what is happening in higher education, you’ve likely heard of massive open online courses (MOOCs). They have been covered by NY Times, Chronicle of Higher Education, TV programs, newspapers, and a mess or blogs. While MOOCs have been around since at least 2008, the landscape has changed dramatically over the past 10 months. In this timeframe, close to $100 million has been invested in corporate (Udacity) and university (EDx and Coursera) MOOCs . Harvard plans to boldly go with 'Spocs' Image copyright Harvard X Keep up, keep up. If you've only just caught on to the concept of online university courses called Moocs, then you're in danger of falling behind again. Harvard, one of the world's most influential universities, is moving on to Spocs - which stands for small private online courses. Nothing to do with Star Trek and sombre Vulcans, but plenty to do with ambitions "to boldly go".

Chinese Satellite Is One Giant Step for the Quantum Internet Cai Yang/Xinhua via ZUMA Wire China’s 600-kilogram quantum satellite contains a crystal that produces entangled photons. China is poised to launch the world’s first satellite designed to do quantum experiments. A fleet of quantum-enabled craft is likely to follow. First up could be more Chinese satellites, which will together create a super-secure communications network, potentially linking people anywhere in the world. A Quick Guide To The History Of MOOCs This Is How Students Use School Websites 8.45K Views 0 Likes It's important to have a proper appearance online.

What is a MOOC? What are the different types of MOOC? xMOOCs and cMOOCs The acronym “MOOC” has been in vogue recently, with lots of discussion about organisations like udacity, coursera and edX. The acronym stands for “Massive Open Online Course.” These organisations provide one interpretation of the MOOC model. They focus on concise, targeted video content – with short videos rather than full-length lectures to wade through – and use automated testing to check students’ understanding as they work through the content. These MOOCS have been dubbed “xMOOCs”. Whilst they include discussion forums, and allow people to bounce ideas around and discuss learning together, the centre of the course is the instructor-guided lesson.
