Complete narration
One off-screen narrator speaks throughout. The text transcribes the narration, not an inventory of music or sound effects. Scene times are navigation markers.
0:00 · A city on Mars
Imagine a city on Mars. People working, learning, making discoveries—and sharing them with people far from home.
0:12 · A lunar community
On the Moon, another community has its own local network. Across these worlds, communication follows different rhythms.
0:22 · Recording a discovery
A researcher records a discovery for a colleague on Earth. His message is ready. But a complete path may not be.
0:34 · Two paths
The faster route is blocked for now. But another route is available. It takes longer, yet it can already carry part of the discovery. Some pieces can travel now. Others wait for the faster link, making use of both opportunities.
0:48 · Later departure, earlier arrival
When the faster link opens, other pieces follow that route—and arrive first, even though they left later.
1:02 · Reassembling the discovery
At the destination, each piece finds its place. Using both paths makes more capacity available. The pieces need not arrive in the order they were sent.
1:18 · Waiting for contact
When no contact is available, information waits within storage and expiry limits. PRP applications can retain messages before transmission and send them when contact returns. Distance still takes time.
1:39 · Local recovery
If a transmission is lost, a relay holding a valid copy can try again. Recovery need not start all the way back at the source. The source retains its copy until end-to-end confirmation, expiry, or cancellation.
2:01 · The discovery arrives
His colleague receives the discovery. Life continues on Mars, on the Moon, and on Earth. Different networks. Different moments. A conversation that reaches beyond the line of sight.
Visual description by scene
Editorial visual descriptions for reading, not an audio-description track.
0:00–0:12 · A city on Mars
A blond researcher in a rust-colored shirt stands in a populated city under a transparent structure. Plants, pedestrians and transit contrast with the red rocky landscape outside.
0:12–0:22 · A lunar community
Two people consult a tablet inside a planted lunar habitat. Through the windows, buildings and equipment stand on the grey lunar surface. This is another local community, not a mandatory waypoint for the Mars message.
0:22–0:34 · Recording a discovery
At a desk on Mars, the researcher faces a monitor with a colleague's portrait, rock imagery and a recorded-message waveform. A rock sample lies beside the screen.
0:34–0:48 · Two paths
On a dark diagram, a source at left and destination at right have two possible paths. A short direct path is temporarily blocked by a large cross. A longer amber path through relays is available, so numbered pieces begin traveling along it.
0:48–1:02 · Later departure, earlier arrival
The direct route opens in teal. Pieces using it move to the destination while earlier pieces continue along the longer amber route. The arrival display makes the change of order visible.
1:02–1:18 · Reassembling the discovery
Six numbered squares find their positions in a two-row grid. Four teal pieces and two amber pieces distinguish the paths used. The complete arrangement represents one discovery assembled from pieces received at different times.
1:18–1:39 · Waiting for contact
The laboratory view returns behind an inset diagram. A message stays with the sender while the contact path is absent. Text identifies storage and expiry limits; the message can be sent when contact is available again.
1:39–2:01 · Local recovery
A three-stage diagram connects source, satellite relay and destination. The source keeps the original and the satellite keeps a valid copy. After a failed transmission, the relay tries the last leg again; it is not necessary to resend all the way from the source. Text states the source's release conditions: end-to-end confirmation, expiry or cancellation.
2:01–2:22 · The discovery arrives
A dark-haired colleague on Earth watches the researcher's recorded message and rock images on her monitor, with a green city outside. At 2:16, the film moves to the standard cream end card with the PRP logo, title and prp-protocol.org.
