    Mobile Lunar and Planetary Base Architectures

    Space 2003 AIAA 2003-6280 23 - 25 September 2003, Long Beach, California Mobile Lunar and Planetary Bases Marc M. Cohen, Arch.D. Advanced Projects Branch, Mail Stop 244-14, NASA-Ames Research Center, Moffett Field, CA 94035-1000 TEL 650 604-0068 FAX 650 604-0673 [email protected] ABSTRACT This paper presents a review of design concepts over three decades for developing mobile lunar and planetary bases. The idea of the mobile base addresses several key challenges for extraterrestrial surface bases. These challenges include moving the landed assets a safe distance away from the landing zone; deploying and assembling the base remotely by automation and robotics; moving the base from one location of scientific or technical interest to another; and providing sufficient redundancy, reliability and safety for crew roving expeditions. The objective of the mobile base is to make the best use of the landed resources by moving them to where they will be most useful to support the crew, carry out exploration and conduct research. This review covers a range of surface mobility concepts that address the mobility issue in a variety of ways. These concepts include the Rockwell Lunar Sortie Vehicle (1971), Cintala’s Lunar Traverse caravan, 1984, First Lunar Outpost (1992), Frassanito’s Lunar Rover Base (1993), Thangavelu’s Nomad Explorer (1993), Kozlov and Shevchenko’s Mobile Lunar Base (1995), and the most recent evolution, John Mankins’ “Habot” (2000-present). The review compares the several mobile base approaches, then focuses on the Habot approach as the most germane to current and future exploration plans.

  • Water on the Moon, III. Volatiles & Activity

    Water on the Moon, III. Volatiles & Activity

    Water on The Moon, III. Volatiles & Activity Arlin Crotts (Columbia University) For centuries some scientists have argued that there is activity on the Moon (or water, as recounted in Parts I & II), while others have thought the Moon is simply a dead, inactive world. [1] The question comes in several forms: is there a detectable atmosphere? Does the surface of the Moon change? What causes interior seismic activity? From a more modern viewpoint, we now know that as much carbon monoxide as water was excavated during the LCROSS impact, as detailed in Part I, and a comparable amount of other volatiles were found. At one time the Moon outgassed prodigious amounts of water and hydrogen in volcanic fire fountains, but released similar amounts of volatile sulfur (or SO2), and presumably large amounts of carbon dioxide or monoxide, if theory is to be believed. So water on the Moon is associated with other gases. Astronomers have agreed for centuries that there is no firm evidence for “weather” on the Moon visible from Earth, and little evidence of thick atmosphere. [2] How would one detect the Moon’s atmosphere from Earth? An obvious means is atmospheric refraction. As you watch the Sun set, its image is displaced by Earth’s atmospheric refraction at the horizon from the position it would have if there were no atmosphere, by roughly 0.6 degree (a bit more than the Sun’s angular diameter). On the Moon, any atmosphere would cause an analogous effect for a star passing behind the Moon during an occultation (multiplied by two since the light travels both into and out of the lunar atmosphere).

    Moon Landings - Luna 9

    Age Research cards 7-11 years Moon landings - Luna 9 About Credit-Pline On the 3 February 1966, Luna 9 made history by being the first crewless space mission to make a soft landing on the surface of the Moon. It was the ninth mission in the Soviet Union’s Luna programme (the previous five missions had all experienced spacecraft failure). The Soviet Union existed from 1922 to 1991 and was the largest country in the world; it was made up of 15 states, the largest of which was the Russian Republic, now called Russia. The Space Race is a term that is used to describe the competition between the United States of America and the Soviet Union which lasted from 1955 to 1969, as both countries aimed to be the first to get humans to the Moon. Working scientifically The Luna 9 spacecraft had a mass of 98kg (about outwards to make sure the spacecraft was stable the same as a baby elephant) and it carried before it began its scientific exploration. communication equipment to send information back to Earth, a clock, a heating system, a power The camera on board took many photographs of source and a television system. The spacecraft the lunar surface including some panoramic included scientific equipment for two enquiries: images. These images were transmitted back to one to find out what the lunar surface was like; Earth using radio waves. Although the Soviet and another to find out how much dangerous Union didn’t release these photographs to the rest radiation there was on the lunar surface.

    Update on the Qualification of the Hakuto Micro-Rover for the Google Lunar X-Prize John Walker, Nathan Britton, Kazuya Yoshida, Shimizu Toshiro, Louis-Jerome Burtz, Alperen Pala 1 Introduction 1.1 Commercial off the shelf components in space robotics missions In the past several years, due to the proliferation of cubesat and micro-satellite mis- sions, several companies have started offering off-the-shelf space-ready hardware[3]. These products offer a welcome reduction in cost but do not solve a major prob- lem for space robotics designers: available space-ready controllers are years behind COTS microprocessors and microcontrollers in terms of performance and power consumption. For applications involving human safety or critical timing, the extra cost and difficulty of using certified space-ready hardware is justifiable. But for some low-cost missions that require high performance, terrestrial com- ponents are increasingly being qualified and integrated. The University of Tokyo’s HODOYOSHI 3 and 4 satellites have integrated readily available COTS FPGAs and microcontrollers and protected them with safeguards against Single Event Latch-up (SEL)[9]. This paper presets a lunar rover architecture that uses many COTS parts, with a focus on electrical parts and their function in and survival of various tests.

The elemental data of the AXS allow us to not only classification but also quantification of surface rocks on the Moon. The AXS is a compact low-weight instrument for elemental analysis based on the principle of X-ray fluorescence spectrometry using an X-ray spectrometer and two (four) pyroelectric crystals as X-Ray Generators (XRG). This paper introduces the current status of the pre-project to develop an AXS for the SELENE-2 Rover including the investigations on the generation of X-ray flux of the XRG, required surface roughness for the XRS measurement, and a thermal design of the AXS.
