  • Lunar Base Camp Is the First Step Towards the Establishment of a Permanent Lunar Base for Long Duration Human Exploration
    Background NASA and international partners are planning the next steps of human exploration by establishing assets near the Moon, where astronauts will build the systems that are needed for deep space exploration. The space near the Moon offers an excellent environment for testing the systems that are needed for extended exploration missions to other destinations like Mars. To support these missions, NASA is working with commercial partners to develop hardware to support missions around the Moon that are more ambitious than ever before. The first phase of this development effort will utilize current technologies to allow astronauts to gain operational experience spending weeks, rather than days, away from Earth. These missions will enable NASA to develop the techniques and systems that will solve the challenges that astronauts will face when traveling to Mars and other exploration destinations. Although NASA is focusing on Mars exploration as its long term mission planning goal, there are a plethora of exploration missions that can be conducted in cis-lunar space that can extend our knowledge of the solar system and prepare for those future missions. NASA and its international partners are keenly interested in the exploration of the lunar surface and the potential utilization of lunar resources. Establishment of a permanent lunar surface base could provide both experience for astronauts and potential resources that can be utilized to support future Mars missions. The deployment of a lunar base camp is the first step towards the establishment of a permanent lunar base for long duration human exploration. This Request for Proposal seeks an innovative idea and engineering design to commercially procure a fully functional lunar base camp for a planned lunar expedition in 2031.

DOI:10.11728/cjss2018.05.591 China’s Planning for Deep Space Exploration and Lunar Exploration before 2030∗ XU Lin ZOU Yongliao JIA Yingzhuo (State Key Laboratory of Space Weather, National Space Science Center, Chinese Academy of Sciences, Beijing 100190) Abstract The current lunar exploration has changed from a single scientific exploration to science and resource utilization. On the basis of the previous lunar exploration, Chinese scientists and technical experts have proposed an overall plan to preliminarily build a lunar research station on the lunar South Pole by several missions before 2035, exploring of the moon, as well as the use of lunar platforms and in-site utilization of resources. In addition, China will also explore Mars, asteroids and Jupiter and its moons.

  • The Orion Spacecraft As a Key Element in a Deep Space Gateway
    The Orion Spacecraft as a Key Element in a Deep Space Gateway A Technical Paper Presented by: Timothy Cichan Lockheed Martin Space [email protected] Kerry Timmons Lockheed Martin Space [email protected] Kathleen Coderre Lockheed Martin Space [email protected] Willian D. Pratt Lockheed Martin Space [email protected] July 2017 © 2014 Lockheed Martin Corporation Abstract With the Orion exploration vehicle and Space Launch System (SLS) approaching operational status, NASA and the international community are developing the next generation of habitats to serve as a deep space platform that will be the first of its kind, a cislunar Deep Space Gateway (DSG). The DSG is evolvable, flexible, and modular. It would be positioned in the vicinity of the Moon and allow astronauts to demonstrate they can operate for months at a time well beyond Low Earth Orbit. Orion is the next generation human exploration spacecraft being developed by NASA. It is designed to perform deep space exploration missions, and is capable of carrying a crew of 4 astronauts on independent free-flight missions up to 21 days, limited only by consumables. Because Orion meets the strict requirements for deep space flight environments (reentry conditions, deep-space communications, safety, radiation, and life support for example) it is a key element in a DSG and is more than just a transportation system. Orion has the capability to act as the command deck of any deep space piloted vehicle. To increase affordability and reduce the complexity and number of subsystem functions the early DSG must be responsible for, the DSG can leverage these unique deep space qualifications of Orion.

  • The Future of Deep Space Exploration
    The Potomac Institute for Policy Studies CEEDS Center Presents The Future of Deep Space Exploration Potomac Institute for Policy Studies The Future of Deep Space Exploration or decades, the US has led the charge in space exploration. American astronauts were the first to land Fon the moon. NASA’s Pioneer, Galileo, Voyager, NEAR, and Cassini-Huygens missions continued to forge ahead: first to fly by Saturn, Uranus, and Neptune; first to orbit Jupiter and Saturn; first to land on an asteroid and first to land on Titan. These are but a few of the achievements of American deep space exploration over the last five decades. So what efforts are continuing today, and what does the future look like? On October 16, 2019, the Potomac Institute for Policy Studies’ (PIPS) Center for Enterprise, Exploration, and Defense in Space (CEEDS) held a seminar titled: “The Future of Deep Space Explora- tion” to examine and discuss issues related to the next steps in the manned and unmanned exploration of our solar system. It is important to first understand why it is beneficial to continue space exploration. The exploration of space has been a beacon of US leadership since the first moon landing. It has increased American prestige and allowed the US to be the de facto leader in developing the norms of space operations. Space exploration is the perfect opportunity for international collaboration to strengthen partnerships. Like the expedition of Lewis and Clarke, it is the first step in a greater move into the solar system. Without exploration, there can be no return trips, and certainly no permanent home elsewhere in space.

Space Telescope Science Institute, 3700 San Martin Dr., Baltimore MD 21218. ―― In press in Icarus ―― Abstract From observations by the Hubble Space Telescope, Keck II Telescope, and Gemini North Telescope, we have determined the mutual orbit of the large transneptunian object (174567) Varda and its satellite Ilmarë. These two objects orbit one another in a highly inclined, circular or near-circular orbit with a period of 5.75 days and a semimajor axis of 4810 km. This orbit reveals the system mass to be (2.664 ± 0.064) × 1020 kg, slightly greater than the mass of the second most massive main-belt asteroid (4) Vesta. The dynamical mass can in turn be combined with estimates of the surface area of the system from Herschel Space Telescope thermal + 0.50 −3 observations to estimate a bulk density of 1.24−0.35 g cm . Varda and Ilmarë both have colors similar to the combined colors of the system, B–V = 0.886 ± 0.025 and V–I = 1.156 ± 0.029.
