Daniel Barringer, an entrepreneur and mining engineer who had discovered Meteor Crater in 1891, had postulated that it had been caused by the impact of a meteor. About the same time, G. K. Gilbert, the chief geologist of the USGS, examined the crater and announced that it had been created by an explosive venting of volcanic steam. A majority of scientists accepted Gilbert's explanation of the cause of the crater, This theory remained as conventional wisdom until Shoemaker's investigations a half century later.[၈]


Astrogeology and Apollo

[ပလေဝ်ဒါန် | ပလေဝ်ဒါန် တမ်ကၞက်]
Shoemaker training astronauts at Brooks Camp, Katmai National Park[၁၀]

For his Ph.D. degree at Princeton (1960), under the guidance of Harry Hammond Hess, Shoemaker studied the impact dynamics of Barringer Meteor Crater.  Shoemaker noted Meteor Crater had the same form and structure as two explosion craters created from atomic bomb tests at the Nevada Test Site, notably Jangle U in 1951 and Teapot Ess in 1955. In 1960, Edward C. T. Chao and Shoemaker identified shocked quartz (coesite) at Meteor Crater, proving the crater was formed from an impact generating extremely high temperatures and pressures.  They followed this discovery with the identification of coesite within suevite at Nördlinger Ries, proving its impact origin.[၁၁]

In 1960, Shoemaker directed a team at the USGS center in Menlo Park, California, to generate the first geologic map of the Moon using photographs taken by Francis G. Pease.  Shoemaker also helped pioneer the field of astrogeology by founding the Astrogeology Research Program. He was prominently involved in the Lunar Ranger missions to the Moon, joining the television imaging team of Harold Urey and Gerard Kuiper, which turned into a preparatory mission for the future manned landing.  Shoemaker was then chosen to be the principal investigator for the Surveyor program's television experiment, and then the lunar geology principal investigator for Apollo 11, Apollo 12, and Apollo 13.[၁၁]:85-86,92-97,101,119,136

Shoemaker was also involved in the training of the American astronauts.  He himself was a possible candidate for an Apollo Moon flight and was set to be the first geologist to walk on the Moon but was disqualified due to being diagnosed with Addison's disease, a disorder of the adrenal gland.  Shoemaker would train astronauts during field trips to Meteor Crater and Sunset Crater near Flagstaff.[၁၂] He was a CBS News television commentator on the early Apollo missions, especially the Apollo 8 and Apollo 11 missions, appearing with Walter Cronkite during live coverage of those flights.[၁၃]


According to David H. Levy, just before the manned Moon landings,

"With humanity about to set forth upon this new world, geologists and astronomers were divided as to whether the lunar surface was a result of volcanic forces from beneath, or cosmic forces from above.  In 1949, Ralph Baldwin had articulated that the Moon's craters were mostly of impact origin and Gene Shoemaker revived the idea again around 1960.  He saw craters on the Moon as logical impact sites that were formed not gradually, in eons, but explosively, in seconds."[၁၁]:58-59


He was awarded the John Price Wetherill Medal from the Franklin Institute in 1965.


Coming to Caltech in 1969, he started a systematic search for Earth orbit-crossing asteroids, which resulted in the discovery of several families of such asteroids, including the Apollo asteroids. Shoemaker advanced the idea that sudden geologic changes can arise from asteroid strikes and that asteroid strikes are common over geologic time periods.  Previously, astroblemes were thought to be remnants of extinct volcanoes  — even on the Moon.

Comet Shoemaker–Levy 9

[ပလေဝ်ဒါန် | ပလေဝ်ဒါန် တမ်ကၞက်]

In 1993, he co-discovered Comet Shoemaker–Levy 9 using the 18-inch Schmidt camera at Palomar Observatory.  This comet was unique in that it provided the first opportunity to observe the planetary impact of a comet.  Shoemaker–Levy 9 collided with Jupiter in July 1994. The resulting impact caused a massive "scar" on the face of Jupiter.

Death

[ပလေဝ်ဒါန် | ပလေဝ်ဒါန် တမ်ကၞက်]

Shoemaker spent much of his later years searching for and finding several previously unnoticed or undiscovered impact craters around the world.

Shoemaker died on July 18, 1997 during one such expedition in a head-on car collision on the remote Tanami Track, a few hundred kilometers northwest of Alice Springs, Australia. Shoemaker's wife Carolyn was severely injured in the crash.[၁၄][၁၅][၁၆][၁၇][၁၈][၁၉][၂၀][၄]


On July 31, 1999, some of his ashes were carried to the Moon by the Lunar Prospector space probe in a capsule designed by Carolyn Porco.[၂၁][၂၂] He is the only person whose ashes have been buried on any celestial body outside Earth.[၂၃]

The brass foil wrapping of Shoemaker's memorial capsule is inscribed with images of Comet Hale–Bopp ("the last comet that the Shoemakers observed together"),[၂၂] the Barringer Meteor Crater, and a quotation from Shakespeare's Romeo and Juliet reading


And, when he shall die

Take him and cut him out in little stars

And he will make the face of heaven so fine

That all the world will be in love with night

And pay no worship to the garish sun.[၂၁][၂၄]

The fatal crash had happened when Hale-Bopp was still visible to the naked eye, having passed perihelion and having moved into the southern celestial hemisphere.

Awards and tributes

[ပလေဝ်ဒါန် | ပလေဝ်ဒါန် တမ်ကၞက်]

  • Special Award, American Association of Petroleum Geologists, 1997.
  • Shoemaker Award, Texas Section of the American Institute of Professional Geologists, awarded posthumously, 1997.


On July 24, 1997, a memorial for Dr. Eugene Shoemaker and Dr. Jurgen Rahe was presented in the U.S. House of Representatives by California representative George E. Brown, Jr. The memorial was published in the Congressional Record. The memorial credited Shoemaker with being either the discoverer or co-discoverer of 820 asteroids and comets during his career.[lower-alpha     ၄] [၂၆]


A ring-like topographic feature in Western Australia, an astrobleme previously named the "Teague ring" was renamed "Shoemaker Crater" in honor of Eugene M. Shoemaker.


The Near Earth Asteroid Rendezvous space probe was renamed "NEAR Shoemaker" in his honor. It arrived at asteroid 433 Eros in February 2000, and landed on the asteroid after a year of orbital study. He was previously honored with the asteroid 2074 Shoemaker, discovered and named by his colleague, Eleanor F. Helin.[၂၇]
