Within a decade, the number of spacecraft requiring support from NASA’s Deep Space Network (DSN) is expected to increase by a factor of 2–3. Key drivers behind this expectation include NASA’s increasing reliance on more affordable, targeted smallsat missions, a more robust science program in general, and the emergence of multi-element human lunar exploration missions. Given that a proportional increase in the number of antennas needed to communicate with all of these missions might prove prohibitively expensive, NASA has been exploring ways to gain increased capacity from its existing antennas.

摘要

Within a decade, the number of spacecraft requiring support from NASA’s Deep Space Network (DSN) is expected to increase by a factor of 2–3. Key drivers behind this expectation include NASA’s increasing reliance on more affordable, targeted smallsat missions, a more robust science program in general, and the emergence of multi-element human lunar exploration missions. Given that a proportional increase in the number of antennas needed to communicate with all of these missions might prove prohibitively expensive, NASA has been exploring ways to gain increased capacity from its existing antennas.
