Answer:
The interplanetary Internet is a conceived computer network in space, consisting of a set of network nodes that can communicate with each other. These nodes are the planet's orbiters (satellites) and landers (e.g., Curiosity Rover, robots), and the earth ground stations. For example, the orbiters collect the scientific data from the Curiosity rover on Mars through near-Mars communication links, transmit the data to Earth through direct links from the Mars orbiters to the Earth ground stations, and finally the data can be routed through Earth's internal internet.
The speed of light, illustrated here by a beam of light traveling from Earth to the Moon, would limit the speed at which messages would be able to travel in the interplanetary Internet. In this example, it takes light 1.26 seconds to travel from the Earth to the Moon. Due to the vast distances involved, much longer delays may be incurred than in the Earth-bound Internet.
Mars to Earth communication is a simple example of Interplanetary Internet

Interplanetary communication is greatly delayed by interplanetary distances, so a new set of protocols and technology that are tolerant to large delays and errors are required. The interplanetary Internet is a store and forward network of internets that is often disconnected, has a wireless backbone fraught with error-prone links and delays ranging from tens of minutes to even hours, even when there is a connection.
