FUTURE WEEK ON THE SCIENCE CHANNEL


The Science Channel
is having a series of programs this week about the future, beginning with 2057: speculations about what might happen in 50 years, in three parts, The Body, The City, and The World.

Other shows focussing on the future, this week, include Robosapiens, Earth 2100: Wild Weather Ahead, and Deconstruction: House of the Future.

For TV schedules, a nice resource is imdb TV schedules: http://www.imdb.com/sections/tv/

(Note: Unfortunately, The Science Channel may not retain live links to films it has shown in the past, so some links above may not work if the film is not in the current schedule.)

ROVING MARS (THE BOOK)


Steve Squyres book, Roving Mars, is exciting, interesting, and important. It is a page-turner.

Describing the decades long struggle to place scientific experiments on the surface of Mars, and the day-by-day, sometimes second-by-second, thrill of waiting for results to be radioed directly back, live from the surface, he takes us with us, almost in real time, to the experience of probing Mars.





The challenges were scientific, managerial, technical and even psychological (ups and downs as budgets, priorities, technical problems, and deadlines threatened to scuttle the project or suddenly inject into it new life and bigger opportunities).

Squyers, a professor at Cornell University, was the principal scientist for the two robots, Spirit and Opportunity, which landed on Mars years ago and are still returning data.

The most important result of the investigation is solid evidence that water once flowed on Mars. In addition, there are pictures and chemical analyses of the Martian landscape and its soil and rocks.

The years-long struggle he describes points out a number of interesting ideas, issues and questions. Most obvious is the clear fact that no matter how sophisticated the science you wish to do on Mars may be, you can't do it unless you can get there. So the fundamental first step is to develop the engineering technology to build the rockets to get there, the landing system to place stuff safely on the planet surface, and equipment that will work when it arrives, having survived the launch, the journey, the landing, and the Martian environment.

Also interesting is the multifarious role of NASA which itself bears the lead role in often conficting missions and services. NASA:

Rocket science is different from planetary science; science is different from engineering; and the science and engineering (and even the politics) of manned flight is different from that of unmanned flight.

NASA has to worry about

For that matter, politics itself has many forms: there are issues of public, congressional, and presidential politics, of course, but there's also internal politics in NASA and internal politics in the world of science.

NASA has a big job!

Roving Mars is a great introduction to both the scientific world of planetary exploration and the technical, practical and political adventure of exploring another world.
