Details of the landscape of the planet Venus as revealed by the Magellan spacecraft are discussed and illustrated. Advances beyond previous space probes are demonstrated. Details of the program are described. Additional work from this project is proposed. (CW)

X-ray emitting bodies orbiting stars have been located. Research on black holes has brought out many characteristics of these X-ray emitting bodies. (PS)

Discussed are the behaviors of particles and energies in the magnetic fields of neutron stars. Different types of possible research using neutron stars as a laboratory for the study of strong magnetic fields are proposed. (CW)

Assesses the current status of science and technology in India, focusing on developments in agriculture, energy, medicine, space, basic sciences, and engineering. Indicates that although India has benefited in many fields from international collaboration during the last 30 years, the country's leaders have also placed particularly strong emphasis…

Summarizes the agreements between the United States and the Union of Soviet Socialist Republics on cooperation in a number of scientific and technical fields signed during the 1972 Moscow summit meetings. (AL)

The last two decades of collecting evidence to support the plate tectonic theory is reviewed. Discussion also involves how other terrestrial plants show evidence of once having been hot but with long-term stability and no continuing convection. (Author/SA)

A brief summary. Topics include: solid crystals, nonlinear physics, collective phenomena, heavy-ion physics, astrophysics, and particle physics. (BB)

Described is an overview of the Voyager 2 encounter with Neptune. Discussed are the trajectory, atmosphere, rings, satellites, magnetosphere, and future of Voyager 2. (YP)

This article focuses on discoveries in astronomy during the past 20 years using a wide range of observing techniques. The future is seen as a time when astronomers will learn more about the distribution of mass in the universe, the physics of energetic sources, and the intricate interconnections of astrophysical processes. (Author/SA)

The author describes specific examples of the use of technology in science such as fiberoptic spectroscopy to observe galaxies and conduct three-dimensional maps of the universe. Adduces the following examples of technology influencing scientific investigations: gene cloning, gene sequencing, radioimmunoassays, patch-clamping of neurons, scanning…

This is the second half of a two-part article on administration science and technology policy during the period 1977 to 1980. It focuses on activities of the Office of Science and Technology Policy (OSTP) related to national security and foreign policy, space, energy, and the environment, health and agriculture, and OSTP advisory mechanisms and…
