A tool bag slipped away from an astronaut repairing the joint of a solar panel of the International Space Station on Tuesday. The tool bag the size of a small backpack floated away as the spacewalking Heide Stefanyshyn-Piper was wiping away lubricants from her gloves and a camera. The lubricant accidentally leaked from a grease gun.

A discarded Space Station fridge crashed into the Tasman Sea between Australia and New Zealand Nov. 1. Last year, Space Station astronaut Clay Anderson was left with no choice other than to toss the 1,400-pound ammonia tank into space because there was no room left on the shuttle to fly the broken fridge back to Earth, according to the United Kingdom's Daily Mail. It took more than one year for the fridge to penetrate Earth's atmosphere.

Two astronauts aboard the orbiting International Space Station (ISS) have cast their votes for the U. S. presidential elections. ISS Commander E. Michael Fincke and flight engineer Greg Chamitoff filled up an electronic absentee ballot for their choice of candidates using a laptop computer on Monday, according to James Hartsfield, a spokesman at NASA's Johnson Space Center in Houston.

To upgrade airport security equipment, the Transportation Security Administration is selling advertising spaces on plastic bins, carts and stainless steel tables where passengers place their bags for screening. TSA spokesman Sterling Payne said it is part of a 12-month experiment which would permit the placement of advertising materials in selected airport items at 14 American airports including Los Angeles, Denver and Seattle-Tacoma. For the sold ad spaces, TSA already raised $435,000 which it used to purchase new checkpoint gadgets.

A refrigerator-size tank thrown from the space station in July 2007 will fall on Earth on Sunday, the U. S. space agency NASA said Friday. NASA and the U. S. Space Surveillance Network, which tracks objects in space, is monitoring the movement of the 1,400-pound ammonia tank to determine where it will impact and caution people on the ground. Mike Suffredini, NASA's space station program manager, however, assured that there is "a very low likelihood that anybody will be impacted by it," according to Msnbc. com.
