LUNAR NETWORK TRACKING ARCHITECTURE for LUNAR FLIGHT Shane B
LUNAR NETWORK TRACKING ARCHITECTURE FOR LUNAR FLIGHT Shane B. Robinson∗ A trade study was conducted with the objective of comparing and contrasting the radiometric naviga- tion performance provided by various architectures of lunar-based navigations assets. Architectures considered consist of a compliment of two beacons located on the lunar surface, and two orbiting bea- cons that provide range and range-rate measurements to the user. Configurations of these assets include both coplanar and linked constellations of frozen elliptic orbiters and halo orbiters. Each architecture was studied during the lunar-approach, lunar-orbit, and landing phases of a South Pole lunar sortie mis- sion. Navigation filter performance was evaluated on the basis of filter convergence latency, and the steady state uncertainty in the navigation solution. The sensitivity of the filter solution to Earth-based tracking augmentation and availability of range measurements was also studied. Filter performance was examined during the build up of the lunar-based navigation system by exploring different combi- nations of orbiting and surface-based assets. 1 INTRODUCTION The objective of the work outlined in this document is to conduct a parametric trade intended to evaluate some proposed constellations of moon-orbiting navigation and communication beacons. These orbiting beacons are intended to support the lunar missions of NASA’s Constellation program. This study is sponsored by the flight performance systems integration group at JPL (FPSIG), whose work is funded by the NASA Constellation program office. The work outlined in this report will focus on investigating lunar network aided navigation performance during near lunar phases of baseline missions proposed by the Constellation program. -
NASA: Issues for Authorization, Appropriations, and Oversight in the 113Th Congress
NASA: Issues for Authorization, Appropriations, and Oversight in the 113th Congress Daniel Morgan Specialist in Science and Technology Policy July 11, 2013 Congressional Research Service 7-5700 www.crs.gov R43144 CRS Report for Congress Prepared for Members and Committees of Congress NASA: Issues for Authorization, Appropriations, and Oversight in the 113th Congress Summary Spaceflight fascinates and inspires many Americans, but in a time of constrained federal budgets, it must compete with a multitude of other national priorities. As the 113th Congress conducts oversight and considers authorization and appropriations legislation for the National Aeronautics and Space Administration (NASA), an overarching question is how NASA should move forward within budget constraints. The National Aeronautics and Space Administration Authorization Act of 2010 (P.L. 111-267) set a new direction for NASA’s human spaceflight programs. For access to low Earth orbit, including the International Space Station (ISS), it confirmed NASA’s plans to develop a commercial space transportation capability for both cargo and astronauts. The first commercial cargo flight for ISS resupply was conducted in May 2012. Pending the planned availability of commercial crew transportation in 2017, NASA is paying Russia to carry U.S. astronauts to and from the ISS on Soyuz spacecraft. Issues for Congress include the cost, schedule, and safety of future commercial crew services, as well as the need for alternatives if commercial providers do not succeed. For human exploration beyond Earth orbit, the 2010 NASA authorization act mandated development of the Orion Multipurpose Crew Vehicle and the Space Launch System (SLS) rocket to launch Orion into space. -

GAO tested the way si of these contracts are administered and found --a contractor was working without approved llllllllllllllll113606 work orders, --Government-furnished equipment was unac- counted for, --questionable reimbursements occurred for con- tractor costs, I --contract funds increased before the need was justified, I --contracting officers were unaware of their re- sponsibilitres and unfamiliar with contract terms, and I --some contracting officers had a general attitude that small dollar value contracts are not worthy of adequate attention. I ‘/A0 believes overreliance on cost-type contracts which quire greater administration efforts than fixed-price )ntracts contributes to these contracting weaknesses recommends that the National Aeronautics and ace Administration take corrective actions. mp81s2 OCTOBER 21,1900 + Request for copies of GAO reports should be sent to: U.S. General Accounting Office Document Handling and Information Services Facility P.O.

GRAIL Reveals Secrets of the Lunar Interior
GRAIL Reveals Secrets of the Lunar Interior — Dr. Patrick J. McGovern, Lunar and Planetary Institute A mini-flotilla of spacecraft sent to the Moon in the past few years by several nations has revealed much about the characteristics of the lunar surface via techniques such as imaging, spectroscopy, and laser ranging. While the achievements of these missions have been impressive, only GRAIL has seen deeply enough to reveal inner secrets that the Moon holds.

NASA's Planetary Science Lunar Activities and Plans
NASA Lunar Science Activities James L. Green Planetary Science Division NASA Headquarters Washington DC 20546 [email protected] NASA’s Planetary Science Division (PSD) program encompasses a broad range of missions to many destinations in the solar system but the Earth’s Moon holds a special place in these efforts. Our planetary science missions are either strategic or openly competed through announcements of opportunity and are led by a principal investigator (PI). In exploring any particular solar system object, NASA has followed a general paradigm of “flyby, orbit, land, rove, and return.” This prescription has been followed most completely for investigations of the Moon and Mars. The Exploration Systems Mission Directorate (ESMD) will be launching the Lunar Reconnaissance Orbiter (LRO) in 2008 in preparation for manned missions to the Moon. LRO is a strategic mission with competed instrumentation to support exploration goals. After one year of LRO observations, ESMD will transition the spacecraft operations to the PSD for its prime science mission phase. The two competitive PI mission lines in the Planetary Science Division are called Discovery and New Frontiers, both of which have the potential to support Lunar missions. Currently there are three Phase-A studies in competition in the Discovery program which includes the Gravity Recovery and Interior Laboratory (GRAIL) mission by Maria Zuber (PI), MIT. The down-selection for Discovery will be announced later this year. GRAIL proposes to use high-quality gravity field mapping of the Moon to determine its interior structure. The New Frontiers program will next be in competition by late 2008 providing a potential opportunity for a sample return mission from the South Pole-Aitken basin. -
