Abstract The O‐, N‐, Mo‐, Ru‐, Os‐, Cr‐, Ti‐, Ni‐, Fe‐, Nd‐, Ca‐, Zn‐, Sr‐, and Mg‐isotopic compositions of enstatite chondrites are essentially identical to those of the Earth and Moon. These correspondences suggest enstatite chondrites formed at ≈1 AU as the only known chondrite groups that accreted in the vicinity of a major planet. Bulk Earth has a

The Martyrdom of Nadezhda Kurchenko: Soviet Hero Cults and the Spiritual Turn in Late Socialism
Abstract This article argues that the spiritual turn in Soviet atheism under Brezhnev provided a meaningful solution to the problems of producing heroes when self‐sacrificing martyrs were losing their appeal. To support this claim, I examine the story of Nadezhda Kurchenko, a nineteen‐year‐old flight attendant killed by two hijackers on an Aeroflot ...

Optimal trajectory generation for multiple asteroid rendezvous
This thesis is focused on solving one component of the proposed problem in the Global Trajectory Optimization Competition released by the Jet Propulsion Laboratory in late 2006. The goal is to find an optimal spacecraft trajectory to rendezvous with an asteroid in a group of asteroids.

Spacecraft and Asteroid Thermal Image Generation for Proximity Navigation and Detection Scenarios
On-orbit autonomous relative navigation performance strongly depends on both sensor suite and state reconstruction selection. Whenever that suite relies on image-based sensors working in the visible spectral band, the illumination conditions strongly affect the accuracy and robustness of the state reconstruction outputs.
