Brink

Gr 6 Up—Brink provides an investigative look at the recent detection of methane gas in the Martian atmosphere. NASA scientists are trying to determine whether the emissions are due to biological or geological processes. The film looks back into the exploration of Mars from the beginning of the space program. It identifies the different satellites, rovers, and robotics and the data that they have been able to return and also explains how we use various observatories on Earth to collect data. Astronomers, geologists, and specialists in various space oriented fields are interviewed. Simulations, graphs, and charts help them explain whether or not the methane gas indicates that there may be life on Mars. Future missions and even a potential for a manned flight to Mars are discussed. Colorful graphics draw viewers into the presentation. The discussions are lively and it is evident that the scientists are intrigued and excited about the possibilities. There are two awkward breaks in the film where the commercials were inserted when it was aired on television. This film offers a fascinating look at science in action.—Cynde Suite, Bartow County Public Library System, Cartersville, GA
