    FIRST AMERICAN SATELLITE
    January 31, 1958 - United States

    The United States entered the space age by launching the first successful orbiting satellite, Explorer-I, four months after the Soviet launch of Sputnik on 4 Oct 1957. Explorer-I measured cosmic radiation, and led to the discovery of the Van Allen radiation belt. Its instrumentation included temperature sensors, a micrometeorite impact microphone, and a ring of micrometeorite erosion gauges. Data from these instruments were returned by a 60-mW transmitter operating on 108.03 MHz and a 10-milliwatt transmitter operating on 108.00 MHz. Explorer-I was 80-inch long, 6-in diam, weighed 31-lb with 18-lb of payload and was delivered into orbit using a Jupiter-C rocket. The orbit had a period of 114.9 minutes.

    FIRST PRIMATE IN SPACE
    January 31, 1961 - U.S. launched a 4-year-old male chimpanzee

    The U.S. launched a 4-year-old male chimpanzee named Ham on a Mercury-Redstone 2 rocket into suborbital flight to test the capabilities of the Mercury capsule. During his 16.5 minute suborbital flight, Ham experienced about 7 minutes of weightlessness, reached an altitude of 108 miles and a speed of 13,000 mph. He was wired to medical sensors to monitor his vital signs. During flight, Ham performed some simple tasks such as pulling levers when a light came on for a reward of banana pellets. Ham was recovered safely 1,425 miles downrange. This was a test flight before risking the lives of human beings. Now, after Ham's successful flight, NASA was ready to launch the first Mercury astronaut, Alan Shepard, into sub-orbital flight three months later.

    More vehicles are stolen on New Year's Day than any other holiday throughout the year. (So does that mean thieves are having their last fling before changing their ways or are they trying for a big score to start the New Year?)
