Michael Richard Clifford (October 13, 1952 – December 28, 2021) was a United States Army officer and NASAastronaut. Clifford was a Master Army Aviator and logged over 3,400 hours flying in a wide variety of fixed and rotary winged aircraft. He retired from the U.S. Army at the rank of lieutenant colonel. He logged six hours of spacewalk time over three Space Shuttle missions. He was also one of the first people to conduct a spacewalk while docked to an orbiting space station: that spacewalk was conducted during STS-76, while docked at the Russian space station Mir.
As a military officer, Clifford was assigned to the Johnson Space Center in July 1987.[1] As a Space Shuttle Vehicle Integration engineer, his duties involved engineering liaison for launch and landing operations of the Space Shuttle Program; he was involved in design certification and integration of the Shuttle Crew Escape System, and was an executive board member of the Solid Rocket Booster Postflight Assessment Team.[12] Clifford was selected to join NASA Astronaut Group 13 in July 1990.[13] He also served in a variety of technical assignments. From April to August 1991, Clifford was assigned to the Astronaut Office Mission Development Branch where he participated in the design, development, and evaluation of Shuttle payloads and crew equipment having extravehicular activity (EVA) interfaces.[1] From May 1994 to September 1995, he served as lead for space station vehicle/assembly issues.[1] A veteran of three space flights, Clifford flew as a mission specialist on STS-53 in 1992,[14]STS-59 in 1994,[15] and STS-76 in 1996.[16] He has logged 665 hours in space, including a 6-hour spacewalk.[11][17]
STS-53
Flying on the crew of STS-53 which launched from the Kennedy Space Center, Florida, on December 2, 1992, aboard the Space Shuttle Discovery,[14] Clifford became the first member of his 1990 astronaut class. NASA Astronaut Group 13, to reach space.[4] On this mission, he was responsible for a number of experiments, including the Fluid Acquisition and Resupply Experiment (FARE) which he performed with Guion Bluford and Jim Voss[18] He also conducted the Battlefield Laser Acquisition Sensor Test (BLAST) on a novel laser energy detector for the U.S. military.[19][20] After 116 orbits of the Earth, Clifford returned with the rest of the STS-53 crew, which landed at Edwards Air Force Base, California, on December 9, 1992.[14]
STS-59
For his next spaceflight, he served aboard Space Shuttle Endeavour on the STS-59 Space Radar Laboratory (SRL) mission, which launched on April 9, 1994.[15] In this mission, Clifford and five other astronauts worked around the clock on imaging projects using SRL imaging radars, including Spaceborne Imaging Radar, Synthetic-aperture radar, and a carbon monoxide (CO) sensor known as Measurement of Air Pollution from Satellites (MAPS), to collect data on the Earth's surface and atmosphere.[21][22] The mission concluded on April 20, 1994, with a landing at Edwards Air Force Base after orbiting the Earth 183 times.[15]
He was diagnosed with Parkinson's disease a few months after STS-59 by NASA medical staff and Dr. Joseph Jankovic, a neurologist in Houston. At the time, symptoms were mild and limited to the right arm, which was not swinging naturally.[23][24]
STS-76
Despite the Parkinson's diagnosis,[23] Clifford was selected to serve aboard Space Shuttle Atlantis on STS-76, which launched on March 22, 1996. While docked at the Russian space station Mir, Clifford performed a six-hour spacewalk with fellow astronaut Linda M. Godwin to mount experiment packages on the Mir docking module.[16] This was the first spacewalk ever conducted by a NASA crew while a Space Shuttle is docked to an orbiting space station.[11][25] Prior to the spacewalk, he woke up to music composed by his two sons.[26] Following 145 orbits of the Earth, he returned as Atlantis landed at Edwards Air Force Base in California on March 31, 1996.[16]
After the STS-76 mission, Clifford decided that he should not fly, because he did not know how fast the Parkinson's disease was going to progress.[27]
Post-NASA career
Clifford resigned from the astronaut corps and left NASA in January 1997[2] to join Boeing's Defense and Space Group as flight operations manager for the International Space Station Program.[28] He later oversaw Boeing's shuttle program till it was winding down.[29] After about 13 years, he left Boeing in September 2011.[23]
He was diagnosed with Parkinson's disease in 1994 when he was 42 years old.[23] He suspected that exposures to pesticides used in farms and other chemicals used on car engines since he was a youngster contributed to the early onset of his illness.[8] After retirement from his space career in 1997, he became an advocate for Parkinson's disease awareness and encouraged other patients of the disease to live life to its fullest.[33] Filmmaker Zach Jankovic, son of Dr. Joseph Jankovic who helped diagnose Clifford, made a documentary detailing Clifford's experiences with the disease; the short film entitled The Astronaut's Secret won the American Academy of Neurology Foundation's 2012 annual "Neuro Film Festival" competition[34] and was released in 2014.[35][36]
Clifford died from complications of Parkinson's on December 28, 2021, at the age of 69.[2][4][11][29][37]

As a youngster, Mr. Clifford said, he worked in a gas station using degreasers to clean car engines. He also worked on a farm where he used pesticides and in fields where DDT was sprayed. Then, as an aviator, he cleaned engines readying them for test flights. But at none of these jobs was he protected from exposure to hazardous chemicals that are readily inhaled or absorbed through the skin. Now Mr. Clifford, a lifelong nonsmoker, believes that his close contact with these various substances explains why he developed Parkinson's disease at such a young age. Several of the chemicals have strong links to Parkinson's, and a growing body of evidence suggests that exposure to them may very well account for the dramatic rise in the diagnosis of Parkinson's in recent decades.
