The Coldest Days of the Year in Cape Canaveral, Florida: January 28th, 1986

Onizuka and payload specialist Gregory B. Jarvis. On January 28, 1986, this was the coldest day NASA tried to launch a manned spaceship. In fact, it is 36 degrees Fahrenheit, about 15 degrees lower than any previous launch temperature. The takeoff time for Challenger 51-L flight was delayed twice in the morning and all operations and systems seemed to be managed. An "icing" team was sent to the launch pad to remove the ice remaining on the launch pad.

January 28, 1986, NASA planned to launch the Challenger Space Shuttle from the Kennedy Space Center in Cape Canaveral, Florida. The launch was postponed several times. This work attracted a lot of public interest, mainly because the staff included civilians, a teacher of New Hampshire State as Krista McAuliffe. On the eve of the launch, NASA held a long telephone conference with engineers at Morton Thiokol, a contractor who manufactured the Challenger's solid rocket motor. Among them is the old man Allan McDonald of the launch site of Morton Thiokol. Florida is unusually cold - it is expected to be 18 degrees celsius overnight - so McDonald's and other Morton Thiokol engineers recommend to postpone the release again. They explained that the cold weather could damage rubber O-rings and prevent hot gases from escaping the shuttle booster. These boosters have never been tested at less than 53 degrees, and morning forecasts require a much lower temperature than this value.

On Tuesday 40 years ago, car size equipment was launched from Cape Canaveral, Florida. After 35 years, it became the first and only man-made object to enter the space between stars. On the way, travelers explore (2) to make headlines about Jupiter, Saturn and Titan flight. When Voyager was launched, Fran Bagenal was a student and wrote a doctoral dissertation on data from detectors around Jupiter. Professor of astrophysics and planetary science at the University of Colorado Boulder, and former chairman of the NASA External Earth Evaluation Group also participated in Galileo, Deepspace 1, Newvision, and Juno Mission.
