POPS'Interplanetary internet' passes first test The new protocol is somewhat different from the one that forms the backbone of the internet, called TCP/IP. On Earth, if some data is lost between a sender and a recipient, the two communicate back and forth until all the information is sent. That 'handshake' works well on Earth, where the network is almost always continuously connected, says Adrian Hooke, team leader at NASA Headquarters in Washington, DC. But in space, probes pass behind planets and out of range, power outages are common, and distances between planets vary as the planets move in their orbits. In addition, at distances not far beyond the Moon, the time required to beam data between a sender and a recipient makes back-and-forth communication between the two inefficient, says Hooke.

POPSA Solar Prominence Unfurls On September 29, this magnificent eruptive solar prominence lifted away from the Sun's surface, unfurling into space over the course of several hours. Suspended in twisted magnetic fields, the hot plasma structure is many times the size of planet Earth and was captured in this view by the Sun-watching STEREO (Ahead) spacecraft.

POPSSattelite that will measure gravity of Earth. "Most people are taught at school that the acceleration due to gravity at the Earth's surface is 9.8m per second squared - but, in truth, this figure varies around the planet depending on the nature of the material underfoot." "By combining the gravity data with information about sea-surface height gathered by other spacecraft, scientists will be able to track the direction and speed of ocean currents. "If we want to improve our climate models then we need to improve our knowledge of how the oceans move, and Goce will help us do that," mission scientist Dr Mark Drinkwater, from the European Space Agency (Esa), told BBC News.

POPS China Attempted To Blind U.S. Satellites With Laser Not quite sharks with laserbeams, but cool tech none the less. Intersting that the US seems to be ok with the practice. Granted the atricle says "attempted", but the state dept. also hinted in the article that china has been devloping this for years. How long before they can blind the spy satalites?
