Remembering Astronaut Ronald E. McNair

Published on Jan 27, 2013

On January 28, 1986, NASA Challenger mission STS-51-L ended in tragedy when the shuttle exploded 73 seconds after takeoff.  On board was physicist Ronald E. McNair, who was the second African American to enter space. But first, he was a kid with big dreams in Lake City, South Carolina.

From NASA biography:

Graduated from Carver High School, Lake City, South Carolina, in 1967; received a bachelor of science degree in Physics from North Carolina A&T State University in 1971 and a doctor of philosophy in Physics from Massachusetts Institute of Technology in 1976.

Graduated magna cum laude from North Carolina A&T (1971); named a Presidential Scholar (1967-1971), a Ford Foundation Fellow (1971-1974), a National Fellowship Fund Fellow (1974-1975), a NATO Fellow (1975); winner of Omega Psi Phi Scholar of the Year Award (1975), Los Angeles Public School Systems Service Commendation (1979), Distinguished Alumni Award (1979), National Society of Black Professional Engineers Distinguished National Scientist Award (1979), Friend of Freedom Award (1981), Whos Who Among Black Americans (1980), an AAU Karate Gold Medal (1976), five Regional Blackbelt Karate Championships, and numerous proclamations and achievement awards.

While at Massachusetts Institute of Technology, Dr. McNair performed some of the earliest development of chemical HF/DF and high-pressure CO lasers. His later experiments and theoretical analysis on the interaction of intense CO2 laser radiation with molecular gases provided new understandings and applications for highly excited polyatomic molecules.

In 1975, he studied laser physics with many authorities in the field at Ecole Dete Theorique de Physique, Les Houches, France. He published several papers in the areas of lasers and molecular spectroscopy and gave many presentations in the United States and abroad.

Following graduation from MIT in 1976, he became a staff physicist with Hughes Research Laboratories in Malibu, California. His assignments included the development of lasers for isotope separation and photochemistry utilizing non-linear interactions in low-temperature liquids and optical pumping techniques. He also conducted research on electro-optic laser modulation for satellite-to-satellite space communications, the construction of ultra-fast infrared detectors, ultraviolet atmospheric remote sensing, and the scientific foundations of the martial arts.

Selected as an astronaut candidate by NASA in January 1978, he completed a 1-year training and evaluation period in August 1979, qualifying him for assignment as a mission specialist astronaut on Space Shuttle flight crews.

He first flew as a mission specialist on STS 41-B which launched from Kennedy Space Center, Florida, on February 3, 1984. The crew included spacecraft commander, Mr. Vance Brand, the pilot, Commander Robert L. Gibson, and fellow mission specialists, Captain Bruce McCandless II, and Lt. Col. Robert L. Stewart. The flight accomplished the proper shuttle deployment of two Hughes 376 communications satellites, as well as the flight testing of rendezvous sensors and computer programs. This mission marked the first flight of the Manned Maneuvering Unit and the first use of the Canadian arm (operated by McNair) to position EVA crewman around Challengers payload bay.

Included were the German SPAS-01 Satellite, acoustic levitation and chemical separation experiments, the Cinema 360 motion picture filming, five Getaway Specials, and numerous mid-deck experiments — all of which Dr. McNair assumed primary responsibility. Challenger culminated in the first landing on the runway at Kennedy Space Center on February 11, 1984. With the completion of this flight, he logged a total of 191 hours in space.

Dr. McNair was assigned as a mission specialist on STS 51-L. Dr. McNair died on January 28, 1986 when the Space Shuttle Challenger exploded after launch from the Kennedy Space Center, Florida, also taking the lives of the spacecraft commander, Mr. F.R. Scobee, the pilot, Commander M.J. Smith (USN), mission specialists, Lieutenant Colonel E.S. Onizuka (USAF), and Dr. J.A. Resnik, and two civilian payload specialists, Mr. G.B. Jarvis and Mrs. S. C. McAuliffe.

Normalizing Risks

Today:  The Challenger 25th Anniversary

Many fire fighters and paramedics working today were not yet alive when one of the most stunning events in the history of American spaceflight occurred on this day in 1986: the space shuttle Challenger exploded just over a minute after take-off killing all aboard.

The flight crew knew they were in trouble as Michael Smith uttered the now famous “uh-oh” when he saw indications of an ominous pressure drop on his instrument panel as Challenger cleared the pad. Challenger was being propelled downrange by the three main engines and two solid rocket boosters that would burn out and separate from the spacecraft as it climbed out to earth orbit.

Challenger was launched that bitter cold Florida morning amidst a heated discussion involving some Morton Thiokol contractors and others about the safety and reliability of seals between sections of the solid rocket booster stacks. The concern was that the frigid cold would affect their ability to correctly expand and seal the gaps in the rocket motor as it ignited and pressurized in a fraction of a second.

Remember this about Challenger: Booster seals had repeatedly failed to seal completely in prior launches, occasionally causing hot gas exposure to the secondary seal and some damage to the booster itself but a rocket motor had never failed catastrophically or contributed to a major emergency. Because of this, NASA had accepted or “normalized” increasing levels of risk. They came to see seal damage as normal and part of most launches. It was not normal—it was an indication of a basic design flaw waiting for an unfortunate confluence of factors. Those factors came together on January 28th, 1986.

Multiple smoke puffs are visible in the photo above (arrows). They began at .836 seconds
and continued through 2.500 seconds,occurring about 4 times a second. Upward motion
of the vehicle caused the smoke to drift downward and blur into a single cloud.

Within seconds both seals failed and hot exhaust gases and eventually a jet of flame shot from the motor and impinged on the main fuel tank. Challenger exploded shortly thereafter.
