Science AMA Series: We’re NASA space communications engineers working on
technology for the interplanetary internet – Ask Us Anything!
Hi, we’re NASA engineers working on space communications technologies
that will help create an interplanetary internet. When data travels vast
distances like the 30+ million miles to Mars, the potential for delay or
disruption is significant! Network disruption in space can happen
because of limited contact time and atmospheric effects. NASA
communications technology called ‘disruption-tolerant networking’ (DTN)
allows for temporary disruptions and long delays, unlike the familiar
computer to computer IP connection. DTN can also provide tremendous
benefits to missions closer to Earth and terrestrial applications.
That’s what we’re working on, and it has the potential to improve data
transmission for virtually all of NASA’s missions. We are: Vint Cerf,
