The article provides an overview of the U.S. National Aeronautics and Space Administration's (NASA) Asteroid Redirect Mission (ARM), which is the only human deep space mission of NASA. Topics discussed include the preferred asteroid retrieval technique for ARM, NASA's building of an Asteroid Capture Testbed at Jet Propulsion Laboratory and its preference to capture and redirect a small near-Earth asteroid.

The article discusses the need to find near-Earth objects (NEOs) for human and robotic exploration. A good astronaut exploration target, it says, should be complex and larger than 30 meters in diameter, should present a low-delta-V mission opportunity from Earth and the exploration mission taking not more than six months. It also notes the Spaceguard Survey of NEOs, the Target NEO report and the Science Mission Directorate.

The article focuses on the International Space Station (ISS), born on December 7, 1998 and which, on October 25, 2010, became the longest continually inhabited space station in history. The space station's 108.5 meter backbone supports solar arrays which generate the power needed for scientific research, the station's original purpose. During its first ten years of life, the orbiting laboratory has supported more than 600 experiments. As of November, 2010, more than 196 individuals have visited the ISS.

The article offers the author's insights regarding his experience on being a volunteer astronaut at the National Aeronatics and Space Administration (NASA) and accepting the risk of spaceflight. Topics discussed include meeting space shuttle astronaut Dick Scobee, his belief on the benefits of mining the moon and the asteroids for water and radiation shielding in risk reduction, and the testing of space taxis.

The article offers the author's view on the defence against celestial bodies such as asteroids. He mentions that astronomers from the U.S. National Aeronautics & Space Administration (NASA) consider smaller near earth asteroids (NEAs) to have greater risk than larger ones. An overview of the Chelyabinsk airburst is also presented.

The article explains the importance of T-38 training jet in the Spaceflight Readiness Training (SFRT) for astronauts at the National Aeronautics and Space Administration (NASA). Topics covered include T-38 cockpits with duplicate controls for honing critical pilot skills in T-38 training and making good decisions in case of systems malfunction. Also mentioned are modifications on the Northrop T-38 Talon that first flew in 1959, the T38N weather radar and global positioning system (GPS).

The article focuses on various space exploration missions intended to expand knowledge about asteroids. It discusses the significance of asteroids involving their mineral reserves, preservation of environmental and chemical conditions and water reserves, the missions of the National Aeronautics and Space Administration (NASA) spacecraft Dawn robotic to main belt asteroid 4 Vesta and dwarf planet 1 Ceres, and a NASA sample return mission to the near-Earth asteroid Bennu.

The article offers a look at some of the questions on the Asteroid Redirect Mission (ARM) a proposal of the United States National Aeronautical and Space Administration (NASA) to capture an asteroid and move it closer to Earth. Topics discussed include the budget requested by the U.S. President Barack Obama for the project and the current mission concept.

The author shares his experience in recording images from space of the earth's geology, biosphere and oceans on board the space shuttle Endeavor. He also recounts Endeavor's movements and distances in space, the Spaceborne Imaging Radar C/X-band Synthetic Aperture Radar, and the processing of imageries using high-speed data recorders. He also remembers galley rehydration, an encounter with an asteroid dust that caused short circuit, and recounts the significance of Endeavor's mission.
