Michael John Smith (April 30, 1945 – January 28, 1986), usually known as Mike Smith, was an American astronaut—pilot of the Space Shuttle Challenger when it was destroyed during the STS-51-L mission. All seven crew members died.

Smith was born in Beaufort, North Carolina. He graduated from the United States Naval Academy in 1967 and subsequently attended the U.S. Naval Postgraduate School at Monterey, California. He completed naval aviation jet training at Naval Air Station Kingsville, Texas, receiving his aviator wings in May 1969. He was then assigned to the Advanced Jet Training Command (VT-21) where he served as an instructor from May 1969 to March 1971. During the 2-year period that followed, he flew A-6 Intruders and completed a tour during the Vietnam War while assigned to Attack Squadron 52 (VA-52) aboard the USS Kitty Hawk (CV-63). In 1974, he graduated from U.S. Naval Test Pilot School and was assigned to the Strike Aircraft Test Directorate at NAS Patuxent River, Maryland, to work on the A-6E TRAM and Cruise missile guidance systems. He returned to the U.S. Naval Test Pilot School in 1976 and completed an 18-month tour as an instructor. From Patuxent River, he was assigned to Attack Squadron 75 (VA-75), where he served as maintenance and operations officer while completing two Mediterranean deployments aboard the USS Saratoga. He flew 28 different types of civilian and military aircraft, logging 4,867 hours of flying time. He was promoted posthumously by Congress to the rank of Captain, and has had a Chair named in his honor at the Naval Postgraduate School.

Astronaut career

Smith was selected for the astronaut program in May 1980; he served as a commander in the Shuttle Avionics Integration Laboratory (SAIL), Deputy Chief of Aircraft Operations Division, Technical Assistant to the Director, Flight Operations Directorate, and was also assigned to the Astronaut Office Development and Test Group. In addition to being pilot on the Challenger, he had been slated to pilot a future Shuttle mission (STS-61-N) which had been scheduled for the Fall of 1986.

Smith's voice was the last one heard on the Challenger voice recorder, saying "Uh,oh". The Shuttle broke up 73 seconds into the flight, and at an altitude of 48,000 feet (14.6 km).

While analyzing the wreckage, investigators discovered that several electrical system switches on Smith's right-hand panel had been moved from their usual launch positions. Fellow Astronaut Richard Mullane wrote, "These switches were protected with lever locks that required them to be pulled outward against a spring force before they could be moved to a new position." Later tests established that neither the force of the explosion, nor the impact with the ocean could have moved them indicating that Smith made the switch changes, presumably in a futile attempt to restore electrical power to the cockpit after the crew cabin detached from the rest of the orbiter.

Recognition

Smith was posthumously awarded the Congressional Space Medal of Honor in 2004, along with all astronauts lost in the Challenger and Columbia accidents. He also received the Defense Distinguished Service Medal (posthumous), the Navy Distinguished Flying Cross, 3 Air Medals, 13 Strike/Flight Air Medals, the Navy Commendation Medal with "V" Device, the Navy Unit Citation, and the Vietnam Cross of Gallantry with Silver Star.

The Michael J. Smith Field airfield in his home town of Beaufort, North Carolina is named after Smith.

Smith was portrayed by Brian Kerwin in the 1990 TV movie Challenger.
