Jack Schmidt

Harrison Hagan Schmitt (born July 3, 1935) is an American geologist, and former NASA astronaut, university professor, and politician, who is the most recent living person – and only person without a background in military aviation – to have walked on the Moon.

Born July 3, 1935, in Santa Rita, New Mexico, Schmitt grew up in nearby Silver City, and is a graduate of the Western High School (class of 1953).

He received a B.S. degree in geology from the California Institute of Technology in 1957 and then spent a year studying geology at the University of Oslo in Norway, as a Fulbright Scholar.

He received a Ph.D. in geology from Harvard University in 1964, based on his geological field studies in Norway.

Before joining NASA as a member of the first group of scientist-astronauts in June 1965, he worked at the U.S. Geological Survey's Astrogeology Center at Flagstaff, Arizona, developing geological field techniques that would be used by the Apollo Crews.

Following his selection, Schmitt spent his first year at Air Force UPT learning to become a jet pilot.

Upon his return to the astronaut corps in Houston, he played a key role in training Apollo Crews to be geologic observers when they were in lunar orbit and competent geologic field workers when they were on the lunar surface.

After each of the landing missions, he participated in the examination and evaluation of the returned lunar samples and helped the crews with the scientific aspects of their mission reports.

Schmitt spent considerable time becoming proficient in the CSM and LM systems.

In March 1970 he became the first of the scientist-astronauts to be assigned to space flight, joining Richard F. Gordon Jr. (Commander) and Vance Brand (Command Module Pilot) on the Apollo 15 backup crew.

The flight rotation put these three in line to fly as prime crew on the third following mission, Apollo 18.

When Apollo 18 and Apollo 19 were canceled in September 1970, the community of lunar geologists supporting Apollo felt so strongly about the need to land a professional geologist on the Moon, that they pressured NASA to reassign Schmitt to a remaining flight.

As a result, Schmitt was assigned in August 1971 to fly on the last mission, Apollo 17, replacing Joe Engle as Lunar Module Pilot.

In December 1972, as one of the crew on board Apollo 17, Schmitt became the first member of NASA's first scientist-astronaut group to fly in space.

As Apollo 17 was the last of the Apollo missions, he also became the twelfth and second-youngest person to set foot on the Moon and the second-to-last person to step off of the Moon (he boarded the Lunar Module shortly before commander Eugene Cernan).

Schmitt also remains the only professional scientist to have flown beyond low Earth orbit and to have visited the Moon.

He was influential within the community of geologists supporting the Apollo program and, before starting his own preparations for an Apollo mission, had been one of the scientists training those Apollo astronauts chosen to visit the lunar surface.

Schmitt landed on the Moon with commander Gene Cernan in December 1972.

Schmitt claims to have taken the photograph of the Earth known as The Blue Marble, one of the most widely distributed photographic images in existence.

While on the Moon's surface, Schmitt – the only geologist in the astronaut corps – collected the rock sample designated Troctolite 76535, which has been called "without doubt the most interesting sample returned from the Moon".

Among other distinctions, it is the central piece of evidence suggesting that the Moon once possessed an active magnetic field.

As he returned to the Lunar Module before Cernan, Schmitt is the next-to-last person to have walked on the Moon's surface.

Schmitt resigned from NASA in August 1975 to run for election to the United States Senate as a member from New Mexico.

On August 30, 1975, Schmitt resigned from NASA to seek election as a Republican to the United States Senate representing New Mexico in the 1976 election.

Schmitt campaigned for fourteen months, and his campaign focused on the future.

As the Republican candidate in the 1976 election, he defeated Democratic incumbent Joseph Montoya.

In the Republican primary, held on June 1, 1976, Schmitt defeated Eugene Peirce.

In the election, Schmitt opposed two-term Democratic incumbent Joseph Montoya.

He defeated Montoya 57% to 42%.

He served one term and, notably, was the chairman of the Science, Technology, and Space Subcommittee of the United States Senate Committee on Commerce.

In the 1982 election, Schmitt was defeated by Democrat Jeff Bingaman.

He sought a second term in 1982, facing state Attorney General Jeff Bingaman.

Bingaman attacked Schmitt for not paying enough attention to local matters; his campaign slogan asked, "What on Earth has he done for you lately?"

This, combined with the deep recession, proved too much for Schmitt to overcome; he was defeated, 54% to 46%.

Since the death of Cernan in 2017, Schmitt is the most recent person to have walked on the Moon who is still alive.

After the completion of the Apollo 17 mission, Schmitt played an active role in documenting the Apollo geologic results and also took on the task of organizing NASA's Energy Program Office.

On April 29, 2018, the Schmitt Space Communicator SC-1x named in his honor was carried aboard the Blue Origin New Shepard crew capsule in a project partly funded by NASA.

It launched the first commercial two-way data and wi-fi hotspot service in space and sent the first commercial Twitter message from space.

The three-pound device was developed by Solstar, which Schmitt joined as an advisor, and launched 66 miles above the Earth's surface as a technology demonstration.

The device was admitted to the Smithsonian National Air and Space Museum.
