Guo Ming

Lore & Background

Guo Ming is introduced as a senior engineer at CNSA, where he is deeply involved in the Taiyang Shen probe mission, designed to study the Sun. When Mark Watney is stranded on Mars, the CNSA team, including Ming, realizes that their probe can be repurposed to send a supply package to Watney. Ming becomes the mission's unsung architect, calculating the feasibility of this plan and coordinating with NASA to ensure its success. His technical skills and calm demeanor under pressure make him a vital asset in the international collaboration that ultimately saves Watney's life.

In Their Own Story

The control room hummed with tension as Guo Ming stared at the trajectory calculations on his screen. The Taiyang Shen probe was meant for the Sun, not for Mars. But here he was, rewriting its mission to save a man he had never met. 'The delta-v is tight,' he murmured to his colleague, 'but if we adjust the burn sequence, we can make it work.' His fingers flew across the keyboard, each keystroke a gamble against the void. When the final numbers aligned, he leaned back, allowing himself a small, weary smile. The probe would fly, and a life would hang on its precision. Outside the window, the Beijing skyline glittered, indifferent to the drama unfolding in that room.

Reader's Guide

Guo Ming is a senior engineer at CNSA, known for his expertise in spacecraft trajectory and propulsion. He first appears during the crisis following Mark Watney's stranding on Mars, where he helps devise a plan to use the Taiyang Shen probe to deliver a supply package. His role is technical and collaborative, working closely with CNSA director Zhu Tao and NASA's team. Ming's defining moment comes when he successfully recalculates the probe's trajectory to intercept Watney's location, a critical step in the rescue. He embodies the theme of international cooperation, as his work bridges the gap between Chinese and American space agencies. Ming's skills include advanced orbital mechanics and a pragmatic approach to problem-solving, which he demonstrates under immense pressure. His arc, though secondary, highlights the unsung heroes behind the scenes who made Watney's survival possible—engineers who turned a solar probe into a lifeline.
