His writings claim that advanced civilizations exist or once existed on the Moon, Mars and on some of the moons of Jupiter and Saturn, and that NASA and the United States government have conspired to keep these facts secret. He has advocated his ideas in two published books, videos, lectures, interviews, and press conferences. His views have never been published in peer-reviewed journals.
A popular planetarium lecturer at the Springfield Science Museum, Hoagland produced a program called "Mars: Infinity to 1965" to coincide with the Mariners 3 and 4 missions. Charles Renaud produced a radio program for WTIC (AM) in Hartford, Connecticut, The Night of the Encounter, which covered the July 14, 1965 Mariner 4 flyby of the planet Mars.[note 3] Hoagland was interviewed for the program at the Springfield Science Museum by WTIC announcer Dick Bertel.
In 1976, Hoagland, an avid Star Trek fan, initiated a letter-writing campaign that successfully persuaded President Gerald Ford to name the first Space Shuttle the Enterprise, replacing the previously slated name for the prototype vehicle, Constitution.[note 4] The Enterprise was rolled out for public display on September 17, 1976, Constitution Day.
Hoagland authored the book The Monuments of Mars: A City on the Edge of Forever, and co-authored the book Dark Mission: The Secret History of NASA, which was ranked 21st on November 18, 2007 on The New York Times Best Seller list for paperback nonfiction.
Hoagland runs The Enterprise Mission website, which he describes as "an independent NASA watchdog and research group, the Enterprise Mission, attempting to figure out how much of what NASA has found in the solar system over the past 50 years has actually been silently filed out of sight as classified material, and therefore totally unknown to the American people."
While Hoagland makes frequent reference to his receipt of the "International Angstrom Medal for Excellence in Science" in August 1993, the organization that awarded the medal, The Angstrom Foundation Aktiebolag, founded by Lars-Jonas Ångström, was not authorized by Uppsala University or the Royal Swedish Academy of Sciences to make use of the academy's Anders Jonas Ångström memorial medal. The academy has long authorized only Uppsala University to use their medal for the Ångström's Prize (Ångströms premium), awarded yearly by Uppsala professors to physics students. Mr. Ångström stated in May 2000 that although his award to Hoagland was a mistake, he acted with good faith and with good intentions.
On December 9, 2007 Hoagland wrote that the problems NASA was then having with the Engine Cut-off (ECO) low-fuel sensors in the Space Shuttle main fuel tank were due to what he called the "torsion field," which he claimed would never be resolved by conventional engineering.[self-published source] On February 7, 2008, STS-122 launched successfully. In the postlaunch press conference mission managers reported that the ECO sensors had performed flawlessly. The problem had been traced to an external tank feed-through connector — and corrected using perfectly conventional engineering. The mission ended, as planned, on February 20 — and was called a complete success. Hoagland also asserts that the orbital parameters of spin-stabilized satellites are influenced by an anti-gravity field in addition to the energy imparted by their launch rockets, which has been kept secret for fifty years until revealed by himself in August 2008.[self-published source]
During Coast to Coast AM, on May 21, 2009, Hoagland stated that NASA is destroying evidence of life on Mars through the heating of soil samples to high temperatures by the various rovers and landers, which has killed "Martians."[self-published source]
On December 2, 2010, Hoagland said that the Space Shuttle Discovery mission STS-133, then on the launch pad, would be the first post-Newtonian mission.[self-published source] He explained that the spacecraft would be powered to orbit by "... energy ... coming from space, i.e., free energy, hyperdimensional physics, torsion [field] physics ... ," although he did not explain what he meant by that and was not pressed by host George Noory. STS-133 was delayed by needed repairs to the external tank, but launched successfully, and conventionally, on February 24, 2011.
Hoagland released the recording[self-published source] of a National Press Club news conference held on October 30, 2007 in which Hoagland and Ken Johnston, a former NASA employee who worked in the Lunar Receiving Laboratory during the Apollo missions, announced that Johnston was ordered to destroy Apollo lunar images and data 40 years ago. Johnston states that he secretly preserved these Apollo images in a private album of "about 1000 old NASA photos and other memorabilia" from his time at NASA,[self-published source] and some of these images were printed and discussed along with Johnston's story in Dark Mission.[self-published source] In December 2007, Project Camelot released a three-part interview with Hoagland.[self-published source] In it, he discussed "the secret history of NASA," and elaborated on his various claims about the Moon. He also discussed a variety of additional topics, such as "hyperdimensional physics," ancient monuments, the Vatican, consciousness, and the year 2012.
Many scientists have responded to Hoagland's claims and assertions. Professional astronomer Phil Plait described Hoagland as a pseudoscientist and his claims as ridiculous. Prof. Ralph Greenberg asserted that the logic of Hoagland's deductions from the geometry of Cydonia Mensae is flawed and says that he is not a trained scientist in any sense. The claim that the crashing of the Galileo orbiter into Jupiter caused a "mysterious black spot" on the planet has since been disputed by both NASA and Plait. There is photographic evidence that a similar "black spot" was present in imagery of Jupiter taken in 1998. A second image referenced by Plait shows a dark ring which looks similar to the spot Hoagland cited. In 1995, Malin Space Science Systems, NASA prime contractor for planetary imaging, published a paper critiquing claims that the "city" at Cydonia is artificial, the claimed mathematical relationships, and — very specifically — denying any claims about concealing questionable data from the public.
In October 1997, Hoagland received the Ig Nobel Prize for Astronomy "for identifying artificial features on the moon and on Mars, including a human face on Mars and ten-mile high buildings on the far side of the moon." The prize is a parody award given for outlandish or "trivial" contributions to science.

^A private award presented to Hoagland by Lars-Jonas Ångström in Washington, D.C., August 1993; not to be confused with the long-established Ångström's Prize (Ångströms premium), awarded yearly by professors at Uppsala University to physics students.
^The WTIC radio program, A Night of Encounter (submission title), was submitted by WTIC President Paul W. Morency as an entry for a Peabody Award, but it did not win. Contrary to what Hoagland states on his biography page, the program was not nominated for the award since there is no intermediate level of competition. All winners are chosen directly from the entire field of accepted entries. The entry form, along with an archival 7" 45 rpm gramophone audio recording of the program, are currently being held at the Hargrett Rare Book and Manuscript Library at the University of Georgia Libraries in Athens, Georgia. WTIC announcer Dick Bertel hosted the program and interviewed Hoagland. The program also featured a conversation between Hoagland and astronomer Dr. Robert S. Richardson, associate director of the Griffith Observatory.
^In "Why 'Enterprise?'", The Enterprise Mission credits the 1976 Space Shuttle letter-writing campaign as being "organized by Richard C. Hoagland and a small group of associates, including White House consultant, Jerome Glenn." Glenn is the co-founder and Director of The Millennium Project, a think tank. His résumé posted on his organization's website mentions that he was "instrumental in naming the first Space Shuttle the Enterprise."
