   Explorer 1 – the first U.S satellite Artist's impression of Explorer 1. Credit: NASA/JPL On February 1, 1958, Explorer 1 was launched on an adapted Jupiter C (also called Juno I) rocket from LC-26A at the Cape Canaveral Missile Test Center, becoming the first U.S. satellite. It carried instrumentation for the study of cosmic rays, micrometeorites, and for monitoring of the satellite's temperature. Explorer 1 was the first spacecraft to detect the Van Allen radiation belt. Explorer I satellite installed atop the Jupiter-C launch vehicle. Credit: NASA    Launched late on January 31, 1958 (10:48 p.m. EST, or 03:48 UTC on February 1),  Explorer 1 was the first satellite launched by the United States. Following the launch of the Soviet Union’s  Sputnik 1  on October 4, 1957, the U.S. Army Ballistic Missile Agency was directed to launch a satellite using its Jupiter C rocket developed under the direction of Dr. Wernher von Braun  (1912–1977) .

  Mercury-Redstone 2  Ham – t he first hominid in space A three-year-old chimpanzee, named Ham, in the biopack couch for the MR-2 suborbital test flight. Credit: NASA Mercury-Redstone 2 (MR-2) was launched on a suborbital flight at 16:55 UTC on January 31, 1961, from LC-5 at Cape Canaveral, Florida. The mission was to test the Mercury capsule and the launch vehicle before launching the first American astronaut. The capsule carried a chimpanzee named Ham, the first hominid in space. The capsule and Ham landed safely in the Atlantic Ocean 16 minutes and 39 seconds after launch.    Officially, Ham was known as “Number 65” before his flight, and only renamed "Ham", after the Holoman Aerospace Medical Center, upon his successful return to Earth. He was taught to pull levers in response to the flashing light. Ham was born in July 1957 and was 3 years 8 months old at launch.  The objectives of MR-2 were to: (1) obtain physiological and performance data on a primate in ...

Onizuka, Sharon Christa McAuliffe, Gregory Jarvis and Judith A. Resnik. Credit: NASA On January 28, 1986, 1986, a catastrophic structural failure 73 seconds after liftoff of the Space Shuttle, mission STS-51-L, destroyed the orbiter OV-099 Challenger killing all seven crew members – Francis R. "Dick" Scobee (1939–1986), Michael J. Smith (1945–1986), Ellison S. Onizuka (1946–1986), Judith A. Resnik (1949–1986), Ronald E. McNair (1950–1986), Gregory B. Jarvis (1944–1986) and S. Christa McAuliffe (1948–1986).    The disaster was caused by the failure of the two redundant O-ring seals in a joint in the Space Shuttle's right solid rocket booster (SRB). The record-low temperatures of the launch reduced the elasticity of the rubber O-rings, reducing their ability to seal th...

White II (1930–1967), the astronaut who had performed the first United States extravehicular activity during the Gemini program; and Roger B. Chaffee (1935–1967), an astronaut preparing for his first space flight. ...
