The crew of the International Space Station was forced to activate back-up oxygen generating equipment on Wednesday after the ISS’s main supply system broke down.Russian engineers are struggling to repair the main “Elektron” oxygen supply system, which is located in the Russian Zvezda living module. The system converts water into hydrogen and oxygen.

Both Russian and U.S. officials say the crew is in no danger. Secondary oxygen supplies should last for at least 100 days and a shuttle mission is scheduled to bring fresh supplies to the station in early June.

Michelle Delio writes in wired.com that antigravity devices are being developed that could eventually change the world as we know it. The devices are known as “lifters.” When charged with a small amount of electrical power, they levitate, apparently able to resist Earth’s gravitational forces.

Currently, the devices can only levitate themselves. But developer Tim Ventura and others are working to convert electrical current into a force that can lift and move planes, trains and rocket ships. If that proves possible, the technology that powers lifters could extend the ability to explore space and drastically cut the use of fossil fuels on Earth.

Scientists have long suspected this may be true, but haven?t been able to test it until 911, when the FAA grounded commercial flights nationwide for three days following the terrorist air attacks. They have now discovered that the American climate was noticeably different during those three days.
