Russian Planetary Exploration: History, Development, Legacy, Prospects

, 2007
Russia’s accomplishments in planetary space exploration were not achieved easily. Formerly, the USSR experienced frustration in trying to tame unreliable Molniya and Proton upper stages and in tracking spacecraft over long distances.

Possible Dynamical Pathways to the Misalignment of the VHS 1256–1257 System

The Astrophysical Journal
Circumbinary planets (CBPs) provide a unique window into planet formation and dynamical evolution in complex gravitational environments. Their orbits are shaped not only by the protoplanetary disk but also by the perturbations from two stellar hosts ...

Current Status of Shock Layer Radiation Studies for Planetary Probes

, 2019
Radiative heating by the shock layer gases surrounding an entry probe is an important heating mechanism for many planetary entries. The magnitude of radiative heating for planetary atmospheres may be characterized with flight similarity in a shock tube ...
