SUMMARY: It's mostly empty, but space can still be a dangerous place for spacecraft. They're usually filled with delicate and sensitive scientific equipment, and the first major risk comes with launch. A typical rocket launch is so loud and violent that spacecraft can be shaken apart. Once in space, they need to deal with the temperature extremes, which can range hundreds of degrees above and below freezing. They're blasted by radiation from the Sun and cosmic rays which come from deep space. And the tiny dust in meteor showers can punch holes in the spacecraft because of their tremendous speed. Engineers need to account for all of these when designing them to survive.

<span style='font-size:14pt;line-height:100%'>Question: With no air in space what is the average temperature? Say for example, what kind of temperature(s) are Voyager 1 and 2 experiencing at this time being on the outer limits of our solar system?</span>

yes there are dangers, cosmic rays, temperatures, radiation


BRamos I see you&#39;ve asked about the heat, well it depends how near or far you are from the Sun and if you are facing it or not

You&#39;re front could get burnt while you&#39;re back would be frozen

Take Mercury it more or less has no air at all on it, the day is maybe +350 or + 360 C you&#39;d be cooked, while the night is say
- 170 Celsius way too cold

I know some of you folks are American so that might be an average temp of 340 F ouch that&#39;s hot&#33; The dangers and challanges of outer space are big &#33;

What exactly happenned to opportune the ESA with this press release article? What prompted the article&#39;s publication?

If graviity keeps our solar system stable, could a smaller replicatoin be possible if all the measurment are drawn to an exact scale? Could we make a "tiny solar system?"
