7. In Links Through Space the OUTER SPACE series this week we propose light reading about space. Strange objects in space and I don't mean cosmic blobs or black holes in terminal phase, but rather things that humans have sent or brought with them into Space.
8. Tranquility Base blog - Back in the 1960s, there were 17 astronauts trained by the U.S. Air Force's military space program. After this program was cancelled in 1969, seven astronauts were transferred to NASA, eventually flying on the space shuttle. What happened to the other ten?
9. The Electric Solar Wind Sail (E-sail) is a relatively straightforward system for propellantless propulsion around the solar system by using the solar wind. Here are details of the ESTcube-1 test of a 10 meter long wire that will be the first test in space of this new technology. It will go up in 2013 and then a 100 meter long system on another cubesat will go up in 2014. Then a satellite with more longer wires will try to get away from the Earth's magnetosphere to actually capture the solar wind
10. The first Spacex tests of the Grasshopper reusable rocket have begun with a modest flight and landing of 6 feet altitude. Next up with 100 feet of flight and other progressive tests
