  • Why does NASA have a "master sniffer"?

    Q: Why does NASA have a "master sniffer"?

    A: NASA needs a few good noses. Astronauts can't ventilate their spacecraft while in orbit, so it's up to chief George Aldrich and his team of sniffers to make sure each object doesn't give off an unpleasant smell. More importantly, they look for fumes that could be dangerous or deadly to astronauts in space.

  • Q: How do space probes work?

    A: Space probes carry instruments into space to make measurements that cannot be made on Earth. Temperature, spectrum, magnetic fields and radiation comprise just a few of the types of phenomena measured. Space probes ride atop a rocket and then separate and set a course based on instructions from Earth-based operators and pre-programmed instructions on board. On arrival, the instruments start taking measurements and transmitting them back to Earth.
