question: The Mars One organization's proposal to establish a human colony on Mars is advocated by what famous Astronaut?
answer: Buzz Aldrin
context: Title: The Waters of Mars
  Passage: "The Waters of Mars" is the third episode of the 2008–2010 specials of British science fiction television series "Doctor Who", broadcast on BBC One on 15 November 2009.  It aired on BBC America on 19 December 2009 and was released on DVD and Blu-ray in the UK on 11 January 2010 and in the US on 2 February 2010.  The story is set on Mars in the year 2059 where the Doctor encounters the first human colony, Bowie Base One.  This is commanded by Captain Adelaide Brooke who turns out to be a pivotal character in the history of humanity.  The Doctor must decide whether to use his knowledge of her fate to change history.  According to "Doctor Who" writer and producer Russell T Davies, the special is closely linked to the next two episodes but is not the first part of a three-part story.  The special was dedicated to Barry Letts, the former writer and producer of "Doctor Who" who died in October 2009.  The episode won the 2010 Hugo Award for Best Dramatic Presentation, Short Form.
  Title: Martian Time-Slip
  Passage: Martian Time-Slip is a 1964 science fiction novel by American writer Philip K. Dick.  The novel uses the common science fiction concept of a human colony on Mars.  However, it also includes the themes of mental illness, the physics of time and the dangers of centralized authority.
  Title: Mars Society
  Passage: The Mars Society is an American worldwide volunteer-driven space-advocacy non-profit organization dedicated to promoting the human exploration and settlement of the planet Mars.  Inspired by "The Case for Mars" conferences which were hosted by The Mars Underground at the University of Colorado Boulder, the Mars Society was established by Dr. Robert Zubrin and others in 1998 with the goal of educating the public, the media and government on the benefits of exploring Mars, the importance of planning for a humans-to-Mars mission in the coming decades and the need to create a permanent human presence on the Red Planet.
  Title: Mars analog habitat
  Passage: A Mars analog habitat is one of several historical, existing or proposed research stations designed to simulate the physical and psychological environment of a Martian exploration mission.  These habitats are used to study the equipment and techniques that will be used to analyze the surface of Mars during a future manned mission, and the simulated isolation of the volunteer inhabitants allows scientists to study the medical and psychosocial effects of long-term space missions.  They are often constructed in support of extensive Mars analogs (see List of Mars analogs).  However, sometimes existing natural places are also valued as Mars analogs, such as a high Earth altitude where the pressure is equal to the pressure at the surface of Mars or a certain cave.  Manned Mars habitats are featured in most human Mars missions; an alternative may be terraforming or telepresence.
  Title: Mars One
  Passage: The Mars One organization has proposed to land the first humans on Mars and establish a permanent human colony there by 2035.
  Title: Mars to Stay
  Passage: Mars to stay missions propose astronauts sent to Mars for the first time should intend to stay.  Unused emergency return vehicles would be recycled into settlement construction as soon as the habitability of Mars becomes evident to the initial pioneers.  Mars to Stay missions are advocated both to reduce cost and to ensure permanent settlement of Mars.  Among many notable Mars to Stay advocates, former Apollo astronaut Buzz Aldrin has been particularly outspoken, suggesting in numerous forums "Forget the Moon, Let’s Head to Mars!"  and, in June 2013, Aldrin promoted a manned mission "to homestead Mars and become a two-planet species."  In August 2015, Aldrin, in association with the Florida Institute of Technology, presented a "master plan", for NASA consideration, for astronauts, with a "tour of duty of ten years", to colonize Mars before the year 2040.  The Mars Underground, Mars Homestead Foundation, Mars One, and Mars Artists Community advocacy groups and business organizations have also adopted Mars to Stay policy initiatives.
  Title: Mars Direct
  Passage: Mars Direct is a proposal for a human mission to Mars which purports to be both cost-effective and possible with current technology.  It was originally detailed in a research paper by Martin Marietta engineers Robert Zubrin and David Baker in 1990, and later expanded upon in Zubrin's 1996 book "The Case for Mars".  It now serves as a staple of Zubrin's speaking engagements and general advocacy as head of the Mars Society, an organization devoted to the colonization of Mars.
  Title: Mars Analogue Research Station Program
  Passage: The Mars Analog Research Station Program (MARS) is an international effort spearheaded by The Mars Society to establish a network of prototype research centers where scientists and engineers can live and work as if they were on Mars, to develop the protocols and procedures that will be required for human operations on Mars, and to test equipment that may be carried and used by human missions to the Red Planet.
  Title: Australia Mars Analog Research Station
  Passage: Australia Mars Analogue Research Station (MARS-Oz) is a station in Australia where the Mars Society will conduct geological exploration under constraints similar to those found on Mars.  In 1998, the United States Mars Society agreed to work with Mars Society Australia, a non-profit organization dedicated to the eventual human settlement on the Red Planet, which allowed this project to be administrated in Australia. <ref name="SAO/NASA Astrophysics Data System (ADS)"> </ref> Led by project manager David Willson, this will be the fourth Mars Analogue Research Station Program.  The three previous stations were built in Devon Island in Arctic Canada in July 2000, a desert near Hanksville, Utah, and the Adler Planetarium in Chicago.  The main objective behind the research is to anticipate and resolve conflicts that will arise on a Martian exploration by having a group of scientists and engineers work together and live in an analogue Mars environment.
  Title: Nili Patera dune field
  Passage: Nili Patera is a dune field on Mars.  It is located on top of a lava bed, at the site of an ancient volcano, the Nili Patera caldera of Syrtis Major, near the Martian equator, and it is one of the most active dune fields of Mars.  Its location coordinates on Mars are 8.7° N latitude, 67.3° E longitude.  It is being actively studied by the HiRISE camera, onboard the Mars Reconnaissance Orbiter, at the rate of one image every six weeks.  The study of the movement of the dunes provides information regarding wind variation as a function of time and furthers the study of surface erosion characteristics of the Martian landscape.  This information can then be used for the development and design of future Mars expeditions.  The dunes of the Patera field are of the barchan type and their study by HiRISE was the first one to establish dune and ripple movement of a minimum of 1 m on Mars.  The Patera dune field, was also the first to be investigated using the COSI-Corr software, which was originally developed to analyse the movement of earthbound dunes.  The research results from the evidence provided by the monitoring of the Nili Patera field, indicate sand fluxes of the order of several cubic metres per metre per year, similar to the flux observed at the sand dunes of Victoria Valley in Antarctica.
