The Pontryagin Maximum Principle and asteroid missions

Professor Monique Chyba and graduate student Geoff Patterson from the UH Department of Mathematics have a joint project with Robert Jedicke from the UH Institute for Astronomy to design spacecraft rendezvous missions with Temporarily Captured Orbiters (TCOs), the so-called minimoons, which
form a subset of the population of Near Earth Objects (NEOs).

The spacecraft is parked on a Halo orbit around the Earth-Moon’s L1 or L2 libration points and the criterion to minimize during the transfer is the consumption of fuel.

Using a sun perturbed 4 body model, and indirect methods based on the Pontryagin Maximum Principle, combined with continuation techniques and a direct method to address the sensitivity of the initialization, they compute efficient rendezvous missions to a large pool of synthetic minimoons.

This project is one of the topics at the outreach event Reach for the Stars on December 10, 2014.

Team helps O’ahu students develop mathematical thinking on April 24

pdf5706_3023A team of more than 50 mathematicians and students from the University of Hawaiʻi at Mānoa invite 7th-12th grade and college students to an evening of probability games and exposure to mathematical thinking. The event, Monte Carlo Night, will take place at the UH Mānoa Campus Center Ballroom on Wednesday, April 24, from 6 p.m.-8 p.m. and is free to attend.

This outreach event will be lead by the School and University Partnership for Educational Renewal in Mathematics (SUPER-M). SUPER-M is an outreach program in the Department of Mathematics at the University of Hawaiʻi at Mānoa. Funded by the National Science Foundation and Graduate STEM Fellows in K-12 Education Program, SUPER-M strives to improve the perception of mathematics in the community through various activities and events. SUPER-M has officially partnered with 29 K-12 schools throughout the state since 2009.
