[/.] NASA Plans Probe to the Sun - Page 5

post #41 of 106
Yeah, I was also wondering what would survive a million degrees F or more. If the heat radiates from the sun similar to a flashlight, then the face facing the sun will take the heat and allow the rest of it to stay somewhat cool. How cool "somewhat" cool is, I dont know. Id love to know how they plan on pulling it off.

Thats just the thing, the technology spun off from NASA and the space programs go very far towards "fixing our own problems." There are literally hundreds of medical devices and technologies that have been developed from NASA research, and thats just in the medical department. If you really want to see all of the thousands of spinoffs you can search the NASA spinoff database, which ranges from more comfortable shoes to sewage treatment.

On top of that the government gets a return of about $7 for every $1 spent on NASA, from taxes on the economic growth stimulated by NASA technologies.

After the sun, they should send a probe to where the sun don't shine (Uranus). Very unexplored territory out there. Maybe they'll find a Klingon base or something

I found this:

Quote:
At closest approach, Solar Probe+ will be 7 million km or 9 solar radii from the sun. There, the spacecraft's carbon-composite heat shield must withstand temperatures greater than 1400o C and survive blasts of radiation at levels not experienced by any previous spacecraft. Naturally, the probe is solar powered; it will get its electricity from liquid-cooled solar panels that can retract behind the heat-shield when sunlight becomes too intense. From these near distances, the Sun will appear 23 times wider than it does in the skies of Earth.

Hmm... how old is that info? Modern particle physics has thrown out the idea of light being made of "waves", it is made of photons, which are part of the boson family of elementary particles.

Wow, you guys must know stuff that all the people at NASA are missing! Hurry, you'd better go tell them before it's too late!

That theory was debunked because it was a reverse physics of the livewave, not faster. However, they may be ways to go faster in other experiements and theories.
