NASA investigating "force fields" to protect astronauts

06/27/2005 9:38 AM

Interesting article over the weekend about how NASA is looking into the potential of force fields to protect astronauts on long missions from radiation exposure. The concept of electromagnetic force fields is as follows:

Most of the dangerous radiation in space consists of electrically charged particles: high-speed electrons and protons from the Sun, and massive, positively charged atomic nuclei from distant supernovas. Like charges repel. So why not protect astronauts by surrounding them with a powerful electric field that has the same charge as the incoming radiation, thus deflecting the radiation away?

Your message refers to high speed electrons and protons. A charge that would repel one of those would ATTRACT the other. Giving your ship a charge would also make it interact with existing electric fields, changing your trajectory.

click on the link, the article suggests using an outer array or negatively charges spheres and an inner group or positively charges spheres, then a grounded metal net underneath.

its interesting anyway . . .don't know if it will work
