Aas 07-042 Spheres Operations aboard the Iss: Maturation of Gn&c Algorithms in Microgravity

The docking algorithms were developed incrementally throughout the five tests sessions, making heavy use of the reconfiguration and modularity features of the SPHERES design. The architecture for the docking algorithms is based on the development of smaller simple modules that implement: two estimation algorithms based on extended Kalman filters; mixer functions to convert forces and torques to...

AAS 09-011 SPHERES Demonstrations of Satellite Formations aboard the ISS

Starting in 2007 the SPHERES team expanded its research operations aboard the ISS to include algorithms for formation flight systems. Based on the experiences learned by developing complex docking algorithms, the team began research to mature algorithms to perform imaging maneuvers and add autonomy to allow a formation system initialization and safing in case of failures. The imaging maneuvers ...

Aboard the Isotope Time Machine

Several years ago, paleontologist Shaena Montanari was doing field work in Mongolia’s Gobi Desert when she noticed fragments of dinosaur eggshells in the sand. She knew them by distinctive lines and bumps on their surfaces. Montanari, then a graduate student at the American Museum of Natural History, and now a Royal Society fellow at the University of Edinburgh, realized she could use the fragm...

ISS: Columbus.

In 2001, a total of 13 assembly and logistic flights to the ISS were made, using both Russian launchers and the Space Shuttle, including flights of the first European astronauts, payloads and Multi-Purpose Logistics Modules (MPLMs). Several US, Russian and Canadian elements have already been assembled in orbit and the fourth Expedition Crew is currently onboard. The cornerstone of ESA's contrib...
