Which term best describes the space facility designed to support long-term human habitation and research in orbit?

• A. Hubble Space Telescope
• B. Space Shuttle
• C. Galaxy
• D. Space Station

Answer: (D)

A space station is an orbital facility built to house people for extended periods and to conduct scientific research in microgravity. That combination of long-term habitation with ongoing experiments in space is what sets a space station apart. The Hubble Space Telescope is an observatory in orbit, designed to take images and collect data, not to support living quarters for extended crews. The Space Shuttle was a reusable vehicle used to transport astronauts and supplies to orbit, but it isn’t designed for long-term occupancy or continuous research in space. A galaxy is a vast system of stars and other matter far beyond our solar system, not a habitable research facility. So the term that best fits is space station.
