Uncontrolled rocket body reentries are difficult to predict precisely due to uncertainties in upper atmospheric density and drag.
Uncontrolled rocket body reentries are difficult to predict precisely due to uncertainties in upper atmospheric density and drag.
The claim is specific, empirical, and contestable, passing Step 0. Retrieved papers [2] and [11] directly support the assertion by emphasizing that atmospheric density uncertainties and variations are major drivers of orbit prediction and reentry calculation errors.

Paper [2] notes that uncertainty in atmospheric density estimation is a primary source of orbit prediction error for objects in low Earth orbit.

Paper [11] explicitly states that precise thermospheric mass density prediction is essential yet challenging for satellite orbital tracking and reentry calculations.
