 An agitated passenger who claimed to have a bomb in his backpack was shot and killed by a federal air marshal Wednesday after he bolted franti stanley us cally from a jetliner that was boarding for takeoff, officials said. No bomb was found.It was the first time since the Sept. 11 attacks that an air marshal had shot at anyone, Homeland Security Department spokesman Brian Doyle said. Another federal official said there was no apparent link to terrorism.Marshals ndash; who often fly in teams ndash; regularly train with weapons in aircraft mockups to learn how to shoot safely in very confined and congested spaces, reports CBS News correspondent Bob Orr. All of a sudden he ran through the aisle, waving his arms,  passenger Mary Gardner said on CBS News  The Early Show. Shortly after the gentleman went through first class and out the door, his wife returned back toward coach, apologizing, that her husband was sick and she had to collect her bags,  added passenger Michael Beshears, who describes the passenger s wife  stanley website as  borderline hysterical.          Shortly after the shots rang out she was moving back toward mdash; I think she was attempting to get to the jetway,  Beshears told co-anchor Hannah Storm.  And I have to commend the flight attendant for stopping her there in our row.

 NASA just announced what the Mars 2020 rover will carry to the Martian surface, and one of them sounds like pure sci-fi: MOXIE, a machine that su stanley trinkflaschen cks in carbon dioxide from the Martian atmosphere and pumps out pure oxygen for use in rocket fuel鈥攐r someday, for humans to breathe.     The Mars Oxygen In-Situ Resource Utilization Experiment  MOXIE  is one of seven instruments NASA will strap to the 2020 rover, totaling approximately $130 million in value. Mars Exploration Project lead scientist Michael Meyer didn ;t dance around the possibilities this device could open up: It   extremely useful for future production of rocket fuel, or for when humans explore Mars. It   a real step forward in helping future human exploration of Mars, being able to produce oxygen on the surface of Mars. Of course, when NASA lands the device on Mars in 2020, it will serve mainly as a test device, exploring how the Martian atmosphere, gravity, and other environmental conditions affect oxygen production. As NASA   Bill Gerstenmaier explained: We ;re not so much using the oxygen, but seeing can we generate it, what   the production rate, what   the efficiency. Those are the general kinds of things we ;re looking at with this in-situ device. If you can make propellant for a craft   ascent stage to get off Mars, that really changes the mission design. Or if you can cache and store oxygen before a crew arrives, and  stanley isolierkanne have a habitable en stanley cup becher vironment when we get
