Most of the top records belong to spacecraft experiencing hypersonic speeds during atmospheric re-entry. It is noteworthy that these velocities are often achieved without onboard propulsion, purely through kinetic energy from gravitational acceleration. NASA's Stardust sample return capsule holds the record for the fastest man-made object within the atmosphere, nearing the critical threshold of escape velocity.
