Aerospace transporter and lifting body activities in Europe and potential participation in the development of the space shuttle orbiter
The course of European aerospace research regarding reentry problems is briefly reviewed for the period from 1966 up to the present. The considerable experience gained by Europe, and particularly Germany, is shown to have led to their involvement and participation in the U.S. space shuttle program. The areas of investigation and expected contributions by European cooperation in the shuttle program are outlined.

Seventh Annual Conference on Manual Control
The Seventh Annual NASA/AF/University Conference on Manual Control was held at the University of Southern California from June 2-4, 1971. Some eighty specialists, including colleagues from Canada, Netherlands and West Germany, attended the Conference, which was organized by the authors of this Summary. Generally at this conference there was less emphasis on theory and more on applications than at some previous meetings. In addition to the well-established areas of human operator modeling and display systems, this conference devoted considerable time to the extensions of manual control theory to such diverse areas as automobile driving, air traffic control and industrial management. This interest in meaningful applications of the existing theoretical knowledge in man-machine systems is encouraging and timely.

HELIOS - Co-operative solar probe.
In June 1969, the Federal Republic of Germany and the United States of America agreed on a joint cooperative solar probe project designated HELIOS. This basic agreement provides for the design, development, test and launch of two flight spacecraft (the first in mid-1974 and the second in late 1975) to within 0.3 AU of the sun. The primary purpose of the two spacecraft is to investigate the properties of and processes in interplanetary space in the direction of and close to the sun. In this technical paper, the scientific mission and German and American plans/design to accomplish this mission are presented by the German and United States Project Managers respectively. Emphasis is placed on the advanced technology required to successfully accomplish this mission.

NASA/Max Planck Institute Barium Ion Cloud Project.
NASA and the Max Planck Institute for Extraterrestrial Physics (MPE), Munich, Germany, conducted a cooperative experiment involving the release and study of a barium cloud at 31,500 km altitude near the equatorial plane. The release was made near local magnetic midnight on Sept. 21, 1971. The MPE-built spacecraft contained a canister of 16 kg of Ba CuO mixture, a two-axis magnetometer, and other payload instrumentation. The objectives of the experiment were to investigate the interaction of the ionized barium cloud with the ambient medium and to deduce the properties of electric fields in the proximity of the release. An overview of the project is given to briefly summarize the organization, responsibilities, objectives, instrumentation, and operational aspects of the project.

Preliminary results of ERTS-investigations by W-German investigations
Results are presented of West German investigations into multidisciplinary geoscientific experiments in central Germany and the Alps, and hydrogeological investigations in the Pampa of Argentina based on ERTS-1 data. The main goals of the investigation were achieved. The studies have given a good idea of the possibilities and limitations of ERTS imagery depending on the objectives in question and on the geographical conditions of the areas under investigation. Even in the well known region of central Europe, ERTS has proven its ability of improving present knowledge. In fields such as pollution monitoring and regional planning the satellite techniques should have distinct practical value. For any regional study of less known areas, the value of ERTS imagery can hardly be overestimated.

Unique characterization of lunar samples by physical properties
The measurement of compressional velocity, shear velocity, static compressibility, and thermal expansion of (1) a suite of shocked rocks fron the Ries impact in Germany, (2) a suite of samples cracked by thermal cycling to high temperatures, (3) many terrestrial igneous rocks, and (4) lunar basalts, gabbroic anorthosites, and breccias, indicate that shock metamorphism is the primary cause for values of physical properties of lunar rocks being diffferent from their intrinsic values. Large scale thermal metamorphism, thermal cycling between temperatures of lunar day and night, large thermal gradients, or thermal fatigue could possibly cause minor cracking in the top few centimeters of the lunar regolith, but are probably not important mechanism for extensively changing values of physical properties of lunar rocks.-

Astronautics in past and future
The contributions of Oberth in the development of rocket technology as a basis for the conduction of manned and unmanned space flights are considered, giving attention also to other rocket pioneers, including Ziolkowski, Ganswindt, von Hoefft, and Goddard. Early stages in rocket development in Germany, Russia, and the U.S. are examined. The launching of Sputnik I in October 1957 was the beginning of a new era in the history of mankind. The start of this new era of space exploration and space utilization comes at a time when the limited resources of the earth begin to impose severe restrictions upon the continuing growth of human technology and civilization. It is predicted that the new space technology will provide the means for overcoming these restrictions. Future space programs, which are partly based on the development of the space shuttle, are discussed, taking into account the international aspects of the new plans for the utilization and the study of space.

Electric propulsion - Past history and future prospects
Studies of feasibility and flight mechanics of electric propulsion systems began around 1946. Conceptual systems design started in 1954, experimental development in 1958; flight tests in 1964 and 1970 proved the functioning of electric thrusters in space. Further development of ion thruster systems has concentrated on bombardment ionization in the U.S., and on radiofrequency, bombardment, and surface-contact ionization in West Germany, Great Britain, France, and the USSR. Electrothermal, plasma, and colloid thruster development has been pursued in many countries. Electric thrusters were used successfully during past years for satellite attitude control, and for prime propulsion of the Soviet spacecraft Yantar. Further applications for attitude and position control of satellites are planned.

NASA's international satellite projects and the significance of Helios
An overview is presented concerning the basic NASA ground rules, guidelines, and practices associated with the establishment and conduct of a NASA international cooperative project. The Helios project is the most expensive and scientifically most significant of all of the NASA unmanned cooperative satellites considered. An agreement signed in June 1969 provided for Germany to develop a flight spacecraft with both American and German scientific instruments aboard that would be launched by the U.S. on two separate missions toward the sun. Details of the Helios mission are discussed along with aspects of spacecraft design, subsystem characteristics, and the scientific experiments.

Sensor equipment of the German earth scientific airplane program
The German airplane program for earth scientific research supports the work of a vast staff of earth scientists from universities and federal agencies. Due to their fields of interest, which are in oceanography, hydrology, geology, ecology, and forestry, five test areas were selected which are spread all over Germany. The sensor package, which was designed in accordance with the requirements of this group of scientists, will be installed in a DO 28 D2 type airplane. The sensor equipment consists of a series of 70-mm cameras having different film/filter combinations, a photogrammetric camera, an infrared radiometer, an 11-channel multispectral line scanner, a LANDSAT-compatible radiometer, and a complex avionic system. Along with the airplane, a truck will be equipped with a set of radiometers and other sensor devices for extensive ground-truth measurement; this also includes a cherry picker.
