On his YouTube channel, he makes videos discussing space-related topics and news, mainly concerning up-to-date rocket science developments.

[10] Manley's first few uploads on his YouTube channel, "szyzyg",[11] were assorted home movies that were primarily of his daughter, Skye, some of which involved her playing the game EVE Online.

When the time-lapse reaches the day an asteroid is discovered, it appears on the map as a bright green dot and continues orbiting the Sun.

[13] Manley's later successes came from gaming content, specifically videos about Kerbal Space Program, a spaceflight simulator with accurate Newtonian physics.

Kerbal Space Program is a sandbox game featuring players constructing rockets out of prefabricated parts, attempting to launch them into orbit and explore the solar system of Kerbin.

[14] Later, Manley would go on to play other games such as Elite Dangerous, EVE Online, Surviving Mars and Kerbal Space Program 2, approaching them from his unique professional science perspective.

Around 2018, Manley slowly transitioned away from gaming content, and began focusing heavily on the history of spaceflight and current events in the industry.

[15] From 2022 to 2023, Manley uploaded an irregular series of vlogs documenting his progress in obtaining a private pilot license, becoming certified in April 2023.
