Bolden Testimony
HOLD FOR RELEASE UNTIL PRESENTED BY WITNESS November 17, 2011 Statement of The Honorable Charles F. Bolden, Jr. Administrator National Aeronautics and Space Administration before the Subcommittee on Science and Space Committee on Commerce, Science and Transportation U. S. Senate Mr. Chairman and Members of the Subcommittee, thank you for the opportunity to appear before you today to discuss the outlook for NASA’s human space flight program. This has been a remarkable year, as we have completed assembling and outfitting of the U.S. On-orbit Segment (USOS) of the International Space Station (ISS), allowing us to focus on full utilization of the Station’s research capabilities; taken key steps in moving forward into the future of exploration beyond Low-Earth Orbit (LEO); celebrated the 50 th anniversary of human spaceflight; and witnessed the successful conclusion of the historic Space Shuttle Program. We are also pleased with the progress our industry partners have made in developing an American capability to transport cargo and eventually astronauts to the ISS, and end the outsourcing of this work to foreign governments. More importantly, this will add a critical level of redundancy for transporting cargo and crew to the ISS. A robust transportation architecture is important to ensuring full utilization of this amazing research facility. Enabling commercial crew and cargo transportation systems in LEO allows NASA to focus on developing its own systems for sending astronauts on missions of exploration beyond LEO. This split between commercial and Government systems allows for a cost effective approach to promote a broad base for human exploration by the United States. -

Lewis Research Center Group Brook Park, Ohio Prepared for the First Annual Wireless Power Transmission Conference sponsored by the Center for Space Power, Texas A&M University San Antonio, Texas, February 23-25, 1993 NASA COMPARISONS OF SELECTED LASER BEAM POWER MISSIONS TO CONVENTIONALLY POWERED MISSIONS John M. Bozek National Aeronautics and Space Administration Lewis Research Center Cleveland, Ohio 44135 and Steven R. Oleson, Geoffrey A. Landis, and Mark W. Stavnes Sverdrup Technology, Inc. Lewis Research Center Group Brook Park, Ohio 44142 SUMMARY Earth-based laser sites beaming laser power to space assets have shown benefits over competing power system concepts for specific missions. Missions analyzed in this report that show benefits of laser beam power are low-Earth-orbit (LEO) to geosynchronous-Earth-orbit (GEO) transfer, LEO to low-lunar-orbit (LLO) cargo missions, and lunar-base power. Both laser- and solar-powered orbit transfer vehicles (OTV's) make a "tug" concept viable, which substantially reduces cumulative initial mass to LEO in comparison to chemical propulsion concepts. In addition, electric propulsion OTV's powered by a laser beam have shorter trip times to and from GEO than do competing OTV's powered solely by the Sun. A round-trip savings of 3 months was calculated for the use of a laser OTV tug instead of a solar OTV tug. -
Mission Design for the Lunar Reconnaissance Orbiter
AAS 07-057 Mission Design for the Lunar Reconnaissance Orbiter Mark Beckman Goddard Space Flight Center, Code 595 29th ANNUAL AAS GUIDANCE AND CONTROL CONFERENCE February 4-8, 2006 Sponsored by Breckenridge, Colorado Rocky Mountain Section AAS Publications Office, P.O. Box 28130 - San Diego, California 92198 AAS-07-057 MISSION DESIGN FOR THE LUNAR RECONNAISSANCE ORBITER † Mark Beckman The Lunar Reconnaissance Orbiter (LRO) will be the first mission under NASA’s Vision for Space Exploration. LRO will fly in a low 50 km mean altitude lunar polar orbit. LRO will utilize a direct minimum energy lunar transfer and have a launch window of three days every two weeks. The launch window is defined by lunar orbit beta angle at times of extreme lighting conditions. This paper will define the LRO launch window and the science and engineering constraints that drive it. After lunar orbit insertion, LRO will be placed into a commissioning orbit for up to 60 days. This commissioning orbit will be a low altitude quasi-frozen orbit that minimizes stationkeeping costs during commissioning phase. LRO will use a repeating stationkeeping cycle with a pair of maneuvers every lunar sidereal period. The stationkeeping algorithm will bound LRO altitude, maintain ground station contact during maneuvers, and equally distribute periselene between northern and southern hemispheres. Orbit determination for LRO will be at the 50 m level with updated lunar gravity models. This paper will address the quasi-frozen orbit design, stationkeeping algorithms and low lunar orbit determination. INTRODUCTION The Lunar Reconnaissance Orbiter (LRO) is the first of the Lunar Precursor Robotic Program’s (LPRP) missions to the moon. -

Hoyt, Ph.D. ABSTRACT The Phase I effort developed a design for a space systems architecture for repeatedly transporting payloads between low Earth orbit and the surface of the moon without significant use of propellant. This architecture consists of one rotating tether in elliptical, equatorial Earth orbit and a second rotating tether in a circular low lunar orbit. The Earth-orbit tether picks up a payload from a circular low Earth orbit and tosses it into a minimal-energy lunar transfer orbit. When the payload arrives at the Moon, the lunar tether catches it and deposits it on the surface of the Moon. Simultaneously, the lunar tether picks up a lunar payload to be sent down to the Earth orbit tether. By transporting equal masses to and from the Moon, the orbital energy and momentum of the system can be conserved, eliminating the need for transfer propellant. Using currently available high-strength tether materials, this system could be built with a total mass of less than 28 times the mass of the payloads it can transport. -

(NYSE: MOG.A and MOG.B) will highlight its Space technology capabilities at the 36th annual Space Symposium in Colorado Springs, CO August 23-26. Moog with be at booth #1030 in the North Exhibit Hall at The Broadmoor. Visit us at Space Symposium to discover more about the following featured technologies: The Small Launch Orbital Maneuvering Vehicle (SL-OMV) is a propulsive tug for secondary payload deployment focused on Venture Class Launch Vehicles. It is payload configurable for cubesats through ESPA-Class spacecraft. It can be used to disperse cubesat constellations or deliver ESPA- Class spacecraft to their ideal orbit. The SL-OMV has its own avionics, power, green propulsion, and communications systems that are configurable for short duration missions. Additionally, Moog’s next generation, radiation-hardened Integrated Avionics Unit (IAU) will be on display. NASA recently selected our IAU and Spacecraft Energization and Power Interfacing Assembly to be the main computer and power source for the VIPER rover, which will land on the Moon’s South Pole to scout possible landing sites for NASA’s Artemis Program. Furthermore, Moog and industry Partner Unibap have teamed to produce next-generation Payload Graphics Processing Units (GPU) for LEO, MEO and GEO missions. We will have live demonstrations daily at 1 p.m. in booth #1030. Many of our solutions on display support human exploration, including NASA’s Artemis missions.
