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. -

Development of the Crew Dragon ECLSS
ICES-2020-333 Development of the Crew Dragon ECLSS Jason Silverman1, Andrew Irby2, and Theodore Agerton3 Space Exploration Technologies, Hawthorne, California, 90250 SpaceX designed the Crew Dragon spacecraft to be the safest ever flown and to restore the ability of the United States to launch astronauts. One of the key systems required for human flight is the Environmental Control and Life Support System (ECLSS), which was designed to work in concert with the spacesuit and spacecraft. The tight coupling of many subsystems combined with an emphasis on simplicity and fault tolerance created unique challenges and opportunities for the design team. During the development of the crew ECLSS, the Dragon 1 cargo spacecraft flew with a simple ECLSS for animals, providing an opportunity for technology development and the early characterization of system-level behavior. As the ECLSS design matured a series of tests were conducted, including with humans in a prototype capsule in November 2016, the Demo-1 test flight to the ISS in March 2019, and human-in-the-loop ground testing in the Demo-2 capsule in January 2020 before the same vehicle performs a crewed test flight. This paper describes the design and operations of the ECLSS, the development process, and the lessons learned.

Future Space Launch Vehicles
Future Space Launch Vehicles S. Krishnan Professor of Aerospace Engineering Indian Institute of Technology Madras Chennnai - 600 036, India (Written in 2001) Introduction Space technology plays a very substantial role in the economical growth and the national security needs of any country. Communications, remote sensing, weather forecasting, navigation, tracking and data relay, surveillance, reconnaissance, and early warning and missile defence are its dependent user-technologies. Undoubtedly, space technology has become the backbone of global information highway. In this technology, the two most important sub-technologies correspond to spacecraft and space launch vehicles. Spacecraft The term spacecraft is a general one. While the spacecraft that undertakes a deep space mission bears this general terminology, the one that orbits around a planet is also a spacecraft but called specifically a satellite more strictly an artificial satellite, moons around their planets being natural satellites. Cassini is an example for a spacecraft. This was developed under a cooperative project of NASA, the European Space Agency, and the Italian Space Agency. Cassini spacecraft, launched in 1997, is continuing its journey to Saturn (about 1274 million km away from Earth), where it is scheduled to begin in July 2004, a four- year exploration of Saturn, its rings, atmosphere, and moons (18 in number). Cassini executed two gravity-assist flybys (or swingbys) of Venus one in April 1998 and one in June 1999 then a flyby of Earth in August 1999, and a flyby of Jupiter (about 629 million km away) in December 2000, see Fig. 1. We may note here with interest that ISRO (Indian Space Research Organisation) is thinking of a flyby mission of a spacecraft around Moon (about 0.38 million km away) by using its launch vehicle PSLV. -

NASA Technical Memorandum 106110 Comparisons of Selected Laser Beam Power Missions to Conventionally Powered Missions John M. Bozek National Aeronautics and Space Administration Lewis Research Center Cleveland, Ohio and Steven R. Oleson, Geoffrey A. Landis, and Mark W. Stavnes Sverdrup Technology, Inc. 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. -
THE HELIUM NEAR SPACE LABORATORY Human Near Space Access, Now, More Affordable, Reliable and Safe
66th International Astronautical Congress, Jerusalem, Israel. Copyright ©2015 by the International Astronautical Federation. All rights reserved. IAC-15-B3.2.8.30387 THE HELIUM NEAR SPACE LABORATORY Human Near Space Access, Now, More Affordable, Reliable and Safe. Annelie Schoenmaker, David Ferrer Desclaux, José Mariano López-Urdiales, Gerard Illana Meler zero2infinity SL Cerdanyola del Vallès, Barcelona, Spain +34 935 824 422 [email protected], [email protected], [email protected], [email protected] Abstract The HELIUM (High European Laboratory for Institutes, Universities and Markets) project offers European and international companies, researchers and scientists a platform to access Near Space. Space technologies are on a continuous growth path and many new developments (related to flag-ship Space programmes like Galileo or Copernicus, and a long tail of other Space initiatives) need to be tested, demonstrated and validated before being accepted by the industry. Currently, these newly developed technologies are tested on the ground, using climatic chambers that simulate one, or a few, Space conditions. However, it remains difficult to simulate the integrated effect of all Space conditions. It’s even more difficult to have a human in the loop, which can help understand the interactions between the environment and the experiment. zero2infinity is developing a balloon-borne laboratory that provides cost effective access to Near Space. It’s an environmentally friendly solution that. In Europe there is an increasing demand of flight opportunities to test, validate, demonstrate and calibrate technologies, equipment and new concepts that need to increase their TRL. This is essential to retain the competitiveness of the European Space sector. -
