Deep space exploration (or deep-space exploration) is the branch of astronomy, astronautics and space technology that is involved with exploring the distant regions of outer space. However, there is little consensus on the meaning of "distant" regions.
May 24, 2023 · Space, outer space and deep space are used somewhat interchangeably in many contexts, but astronomers have come up with clear distinctions between them. So, what's the difference between them?
Jul 12, 2022 · Webb's First Deep Field shows galaxy cluster SMACS 0723, revealing thousands of galaxies from the early universe. See how Webb's Near-Infrared Camera and Mid-Infrared Instrument observe light from billions of years ago.
- Systems to Live and Breathe. As humans travel farther from Earth for longer missions, the systems that keep them alive must be highly reliable while taking up minimal mass and volume.
- Proper Propulsion. The farther into space a vehicle ventures, the more capable its propulsion systems need to be to maintain its course on the journey with precision and ensure its crew can get home.
- The Ability to Hold Off the Heat. Going to the Moon is no easy task, and it’s only half the journey. The farther a spacecraft travels in space, the more heat it will generate as it returns to Earth.
- Radiation Protection. As a spacecraft travels on missions beyond the protection of Earth’s magnetic field, it will be exposed to a harsher radiation environment than in low-Earth orbit with greater amounts of radiation from charged particles and solar storms that can cause disruptions to critical computers, avionics and other equipment.
