The Space Handbook, first published in 1958, was designed to serve as a basic guide on the uses and characteristics of space systems, including astronautics and its applications, technology in the space environment, rocket vehicles, propulsion systems, propellants, internal power sources, structures and materials
Humans have been exploring their world for thousands
of years. People love to discover and learn about new
places. Some of today's explorers are making exciting
new discoveries in space.
Many objects are found in the universe. These
include asteroids, planets, moons, comets, and stars.
Astronomers are scientists who study the objects in
space. People who travel to space to learn about it
are called astronauts.
As part of its ongoing commitment to the nation’s space program, NASA’s
medical leadership asked the Institute of Medicine (IOM) to review specific
aspects of the scientific basis, policies, and procedures associated with the
Longitudinal Study of Astronaut Health (LSAH). NASA created the LSAH in
1992 to address a variety of issues, including both the health of astronauts
during space flight and the longer-term health issues that might be associated
with space flight and flight training.
M1) Assuming that it takes 0.10 s for the driver to react before applying the brakes, what is the stopping distance
(the distance from the point where the driver first sees the need to stop to the point where the car comes to a
stop) for a car traveling at 25 m/s if the deceleration due to the brakes is 3.5 m/s2?
A) 174 m
B) 87 m
C) 186 m
D) 92 m
2) An astronaut stands by the rim of a crater on the moon, where the acceleration of gravity is 1.62 m/s2. To
determine the depth of the crater, she drops a rock and measures...
