Study of the Pioneer Anomaly: A scientific detective story

TL;DR

This paper investigates the Pioneer Anomaly, a mysterious deviation in spacecraft trajectories, using newly recovered data to determine if it stems from onboard forces or other causes.

Contribution

It applies recent Doppler and telemetry data to analyze the Pioneer Anomaly, aiming to clarify its origin and implications for deep space navigation.

Findings

Data suggests possible onboard forces influence the anomaly

Analysis narrows down potential causes of the deviation

Results contribute to understanding spacecraft navigation in deep space

Abstract

NASA's first two deep space missions, Pioneers 10 and 11, have been travelling through the outer solar system for three decades. A slight deviation from their calculated trajectories presents an as yet unsolved scientific mystery. The use of recently recovered Doppler and telemetry data may help us develop a better understanding of this anomaly, and decide whether or not it is due to a force of on-board origin.
