Known as NASA’s SpaceX Demo-2 test flight, which is targeted for lift off at 3:22 p.m. EDT Saturday, May 30, this mission will send NASA astronauts Robert Behnken and Douglas Hurley to the International Space Station as part of the agency’s Commercial Crew Program.
In part IV, we looked at the need to protect spacecraft from the harsh outer space environment while maintaining comfortable temperatures for crews. In this final part, we’ll explore the challenges surrounding keeping human spaceflight crews fed and hydrated during their missions.
In the last part, we discussed different kinds of propulsion systems that might be used to cross vast distances in space at reasonable periods of time. Now, we’ll look at the need to protect spacecraft from the harsh outer space environment and maintain temperatures that are comfortable for human crews.
In part II, we looked at the need for gravity aboard manned spacecraft, and how we might go about achieving artificial gravity in deep space. In this part, we’ll discuss different propulsion systems that might be used on future spacecraft to cross vast distances in reasonable periods of time.
In part I, we examined the size and design elements of future manned spacecraft. Now we will look at the need for gravity aboard manned spacecraft, and how we might go about achieving artificial gravity in deep space.
In his seminal television series Cosmos, the late Dr. Carl Sagan drew a comparison between the Atlantic Ocean that stood in the way of explorers such as Columbus centuries ago and the limits of outer space as we came to know them in the 20th century.
George W. Bush’s (“Bush Jr.’s”) two-term presidency and his national space policy were largely shaped by two tragic events: the terrorist attacks in New York, Virginia, and Pennsylvania on September 11, 2001, and the disintegration of the Columbia space shuttle in 2003.
The United States National Space Policy is the product of the federal government’s effort to set the direction for the national space program. Throughout the history of the American space program, an evolution in space policy — and the process that creates it — has occurred.
