Fallen Astronaut Sculpture Dimensions

Prior to his Apollo 15 lunar mission, astronaut David Scott met Belgian painter and printmaker Paul Van Hoeydonck at a dinner party. It was there agreed that Van Hoeydonck would create a small statuette for Scott to place on the Moon, though their recollections of the details differ. Scott’s purpose was to commemorate those astronauts and cosmonauts who had lost their lives in the furtherance of space exploration, and he designed and separately made a plaque listing fourteen American and Soviet names. Van Hoeydonck was given a set of design specifications: the sculpture was to be lightweight but sturdy, capable of withstanding the temperature extremes of the Moon; it could not be identifiably male or female, nor of any identifiable ethnic group. According to Scott, it was agreed Van Hoeydonck’s name would not be made public, to avoid the commercial exploitation of the US government’s space program. Scott got permission from top NASA management prior to the mission to take the statue aboard his spacecraft, but did not disclose it publicly until a post-mission press conference.

At last, on July 1, 2004, the Cassini spacecraft fired off its breaking rocket, glided into orbit around Saturn, and started taking pictures that left scientists in awe. It wasn't as if they hadn't been prepared for such wonders. The weeks leading up to Cassini's arrival at Saturn had served to intensify their already heated anticipation. It seemed as if each approach-picture taken was more enticing than the one preceding it. "Titan is a very active moon. We already know that about its geology and exotic hydrocarbon cycle. Now we can add another analogy with Earth and Mars: the active dust cycle, in which organic dust can be raised from large dune fields around Titan's equator," Dr. Sebastien Rodriguez explained in a September 24, 2018 NASA Jet Propulsion Laboratory (JPL) Press Release. Dr. Rodriguez is an astronomer at the Universite Paris Diderot, France, and the paper's lead author. The JPL is in Pasadena, California. "We developed new operations methods for INMS for Cassini's final flight through Enceladus' plume. We conducted extensive simulations, data analyses, and laboratory tests to identify background sources of hydrogen, allowing us to quantify just how much molecular hydrogen was truly originating from Enceladus itself," explained Dr. Rebecca Perryman in the April 13, 2017 SwRI Press Release. Dr. Perryman is INMS operations technical lead.
