Ancient history
During the years prior to the Great Purification, the Aspero system was one of many settled by the Forerunners.

Covenant era
The Covenant charted the Aspero system following the empire's formation, and took note of Hesduros' extensive Forerunner presence. As such, the world was named "Silent Hope" by San'Shyuum scholars who sought to unlock the planet's secrets. By the time of the Third Age of Conflict, the manufacturing centre of the Hearth of Aspero was presumably based in this system, and was commissioned to construct the.

Post-war
Following the end of the Human-Covenant War, the Aspero system would become the seat of power for Jul 'Mdama's Covenant, based on the colony world of Hesduros.

Silver Timeline
When questioned as to where the Covenant were going to take the Forerunner keystone, Makee told John-117 that it was to the Aspero system. However, this appeared to be a false lead as the UNSC couldn't find any sign of a planet within the system and Makee betrayed them shortly thereafter.

Despite Makee's betrayal, John believed that Makee had been telling the truth about the system. Cortana determined that due to the influence of cosmic strings on the system, there could be a planet there that the UNSC simply couldn't be seen until they arrived. After a rough slipspace transit in Condor 325, Silver Team arrived in the Aspero system and discovered that John and Cortana were right. Following the retrieval of the keystones, Silver Team fled the system.
