Silversun is a science fiction children's television series made in Australia by the Australian Broadcasting Corporation (ABC).

The show features the adventures of the adolescent members of the crew of the Star Runner, an interstellar spaceship carrying a cargo of 550 cryonically suspended colonists ("cryons") to their new home, the Silver Sun.

In order of appearance: The ABC began showing Silversun on 11 October 2004 at 5:00 pm daily as part of its children's lineup.

Some episodes dealt with issues of ethics and choices unique to science fiction, such as the question of whether the commander's clone should be treated as human or not, the unique human problems encountered by a crew on a lifelong voyage to the stars, and an encounter with a pulsar whose pulse cycle is in phase with the brainwaves of the crewmember Pancha, to her detriment.

Although some first-season episodes are self-contained, the majority deal with multi-episode plot conflicts occurring on board the Star Runner.

These included the illegal re-animation of the character Zandie by the rogue crewmember Degenhardt in the earlier episodes, the crew's encounter with a wormhole, the infection of Commander Cyriax by an alien parasite, his subsequent cure through the use of a harvest clone of him discovered in suspension among the settler pods, and the clone's accidental awakening to full consciousness.

Later, the adult officers are ordered by Cyriax to not attend the crew meeting, where he angrily yells at Mara as a disgrace for trading holophone credits.

Degenhardt hears Cyriax say something about BACKUP 397, so he, Pancha and Mara search the computers to find out what it could mean, disobeying Steve's orders.

Will decides he wants to go back to Earth and before he leaves he uses Tane's idea yet again to unhook the barge from the ship, which creates a huge explosion.

All of its crew had been put into suspended animation, and the answer to why lies in the corrupted log left by Commander Darius.

The missing crew member, Julian Strega, is found after he falls from an upper level and knocks himself unconscious.

He wakes up shortly after on the Star Runner, telling how the Infinity was hit by an asteroid which forced them into a nearby wormhole that wound them up in the Sargasso Disc.

Strega locks Tane out of the bridge and turns the ship towards the centre of the Sargasso Disc, claiming to be able to fix everything by travelling back in time.
