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.

A Change is Gonna Come
by Meredith Grey
"...Change; we don't like it, we fear it, but we can't stop it from coming. We either adapt to change, or we get left behind. It hurts to grow, anybody who tells you it doesn't is lying. But here's the truth: Sometimes the more things change, the more they stay the same. And sometimes, oh, sometimes change is good. Sometimes change is everything...."

about Eyesight Myth and Fact
Myth: Staring at a computer screen all day is harmful to the eyes.
Fact: Spending the day staring at a screen can tire or strain your eyes, but it will not hurt them. Make sure lighting doesn't create a glare on your screen. When spending long periods at your keyboard, take a break now and then to rest your eyes to reduce fatigue. Also, don't forget to blink. Your eyes need to stay lubricated to feel comfortable.
