Astronomical Observability of the Cassini Entry into Saturn

TL;DR

This paper assesses the potential for observing Cassini's entry into Saturn from Earth, using simulations and past spacecraft entry observations to predict visibility as a meteor-like flash.

Contribution

It provides a detailed analysis of the expected observational signatures of Cassini's entry, combining entry dynamics simulations with historical data from Earth spacecraft entries.

Findings

Cassini's entry may be visible as a meteor flash from Earth.

Entry dynamics simulations predict specific observational signatures.

Historical spacecraft entries inform expectations for Cassini's observability.

Abstract

The Cassini spacecraft will enter Saturn's atmosphere on 15th September 2017. This event may be visible from Earth as a 'meteor' flash, and entry dynamics simulations and results from observation of spacecraft entries at Earth are summarized to develop expectations for astronomical observability
