"my battery is low and it's getting dark" – were never sent from Mars
The famous last words attributed to NASA's Opportunity rover, 'my battery is low and it's getting dark,' were never actually transmitted from Mars. Instead, these words originated from a science reporter's paraphrase of the rover's final telemetry data. The myth surrounding the rover's last message has persisted, despite clarifications about its true nature.
- ▪The Opportunity rover landed on Mars in January 2004 and operated for nearly 15 years.
- ▪Its last transmission was a routine data dump, not a poetic message.
- ▪The phrase was coined by a reporter in 2019, summarizing the rover's final telemetry readings.
