An Immigrant’s Journey into the Cosmos
Astronaut Dr. Buzz Aldrin commended the author citing his proposal to transform the Space Shuttle fleet, before retiring it, into a space tourism fleet, which would generate profits for NASA. Dr. Donald Brownlee Director of NASA’s “STARDUST” Mission that flew to comet “Wild 2” said this about the author: “One of Dr. Misconi most significant publications was his 1979 Nature paper on streaming of interstellar grains into the solar system. The paper predicted that interstellar dust should stream into the solar system from the direction, the then detectable interstellar gas and it also described the interaction of the extrasolar particles with the solar wind and the IP (Interplanetar...
Civic Astronomy
The founding of the Dudley Observatory at Albany, N.Y., in 1852 was a milestone in humanity's age-old quest to understand the heavens. As the best equipped astronomical observatory in the U.S. led by the first American to hold a Ph.D. in astronomy, Benjamin Apthorp Gould Jr., the observatory helped pioneer world-class astronomy in America. It also proclaimed Albany's status as a major national center of culture, knowledge and affluence. This book explores the story of the Dudley Observatory as a 150 year long episode in civic astronomy. The story ranges from a bitter civic controversy to a venture into space, from the banks of the Hudson River to the highlands of Argentina. It is a unique glimpse at a path not taken, a way of doing science once promising, now vanished. As discoveries by the Dudley Observatory's astronomers, especially its second director Lewis Boss, made significant contributions to the modern vision of our Milky Way galaxy as a rotating spiral of more than a million stars, the advance of astronomy left that little observatory behind.

Skylab's Astronomy and Space Sciences
The capabilities of Skylab for multidisciplinary investigations are reviewed. Experiments and results are discussed for observations of stars and galaxies, energetic particles, interplanetary dust, Comet Kohoutek, the Earth's atmosphere, and the nature and effects of space environments on man.

LDEF: 69 Months in Space. First Post-Retrieval Symposium, Part 1
LDEF was carried into orbit in April 1984 by the Space Shuttle Challenger. The 11-ton satellite contained 57 experiments to assess the effects of the space environment, i.e., ionizing radiation, meteoroids, cosmic dust, and high altitude atomic oxygen on materials and mechanical, electronic, optical, and living systems. In January 1990, after 69 months in low Earth orbit, LDEF was retrieved by the Space Shuttle Columbia and returned to Earth. The retrieval occurred 57 months after it was originally planned, due in part to the Challenger tragedy. The 69 months in space provided experimenters the unique opportunity to sample and measure the space environment over a longer time period than originally planned. The 57 LDEF experiments were returned to the Principal Investigators and their science teams for analyses and interpretation. In June 1991, over 400 LDEF researchers and data users met in Kissimmee, Florida for the First LDEF Post-Retrieval Symposium. The papers presented contained important new information about space environments and their impact on materials, systems, and biology.
