Teddy Sanders

Lore & Background

Teddy Sanders is the NASA director during the Ares III mission. When Mark Watney is stranded on Mars, Sanders releases the news to the public but decides not to inform the Ares III crew en route to Earth, over flight director Mitch Henderson's strong objection. Later, when astrophysicist Rich Purnell devises an alternative plan to send the Taiyang Shen launcher to resupply the Hermes, which will then use Earth's gravity to 'slingshot' back to Mars two years earlier than Ares IV, Sanders flatly rejects the idea, considering it too risky for the Ares III crew. Henderson surreptitiously sends the proposal to the crew, and they unanimously vote in favor and divert the Hermes. Sanders is forced to support them publicly, but demands Henderson's resignation after the mission.

In Their Own Story

The conference room was silent except for the hum of monitors. Teddy Sanders stared at the satellite image of the Hab, a crumpled silver blister on the rust-red plains of Acidalia Planitia. He had already made the call to release the news to the public that Watney was alive, but he refused to inform the Ares III crew, over Mitch Henderson's strong objection. Later, when Rich Purnell proposed the slingshot plan—sending the Taiyang Shen launcher to resupply the Hermes so it could return to Mars two years early—Sanders flatly rejected it, calling it too risky. But Henderson surreptitiously sent the proposal to the crew, and they unanimously voted in favor. Sanders was forced to support them publicly, but he demanded Henderson's resignation after the mission.

Reader's Guide

Teddy Sanders is the pragmatic leader of NASA, defined by his role as a crisis manager rather than a scientist or engineer. His arc centers on the moral conflict between institutional caution and the human imperative to save Mark Watney. Initially resistant to risky rescue plans, he gradually becomes a key supporter, using his authority to approve the Iris resupply and later the Hermes slingshot maneuver. His skills lie in political navigation, risk assessment, and decision-making under pressure. Defining moments include his initial refusal to divert resources, his tense negotiations with the Chinese space agency (where he trades a future mission for a present life), and his final, emotional approval of the daring rescue plan that brings Watney home—a moment where the bureaucrat finally lets the human win. Sanders represents the real-world constraints of space agencies, making his eventual shift toward hope a powerful character beat.
