Saturday’s CSExtra includes the latest reporting on a spacewalk under way early Saturday aboard the International Space Station for repairs to the external cooling system. Also, new commentary on NASA’s future. A NASA satellite captures images of a large chunk of glacier that has broken away from Greenland. NASA works with Japan and Europe on spacecraft that monitor the Earth and study Mars.
1. From Spaceflightnow.com: NASA astronauts Doug Wheelock and Tracy Caldwell Dyson begin a six to seven hour spacewalk outside the International Space Station early Saturday to repair the external cooling system. Half of the cooling system shut down on July 31. The two astronauts will replace a pump module assembly that experienced an electrical short. The task will require a second spacewalk on Aug. 11. Saturday’s spacewalk was scheduled to begin about 7 a.m., EDT.

2. From Spacepolitics.com: Mike Griffin, the previous NASA administrator, addresses the annual Mars Society convention in Dayton, Ohio with critical words for the Obama administration’s space plans. “We’re not going anywhere and we’re going to spend a lot of money doing it” says Griffin. The former administrator says the U.S. needs a government as well as commercial system for placing astronauts in orbit around the Earth.

A. From Florida Today: A breakdown of the Senate version of a NASA authorization bill that passed unanimously late Thursday. U.S. Sen. Bill Nelson, a Florida Democrat and a chief architect of the legislation, terms the passage “a near miracle.” The measure must be merged with a House version and signed by the President before it becomes law. The measure would fund a new heavy lift rocket and a multi purpose crew spacecraft for deep space missions as well as investments in commercial space transportation systems for trips to Earth orbit by astronauts.
