Flashlights in Space

This came up in the going to outer space thread by @Raccoon City, someone mentioned there is only radiative ability (outside the spacecraft).

I mentioned:

Temperature regulation would be required, and more thermal mass/more surface area to dissipate heat.

That said in space you need dead reliable so a Chinese flashlight does not fit that bill. You may even need intrinsically safe.

Also you are in the spacecraft, you won’t need that many lumens.

What are your thoughts?

"It is critical that there is a credible academic source for the growing and important discipline of alternative facts. This field of study will just keep winning, and we knew that all the best people would want to be on board. There is a real risk in the world today that people might be getting their information about science from actual scientists"

First thing that springs in my mind: do you even need a flashlight in space? There’s no night and day see. you’d need to go quite a distance before you’d loose the light of the sun.

Say you’d be strolling around on the dark side of the moon…., I heard it’s f….. unbelievable cold out of the sun so regular batteries will probably don’t work very well, on the other hand our turbo’s will last much longer so it’s not all bad. Party

Well, spacesuits need heating and cooling to keep the astronaut alive in these extremes so it will probably be easiest to integrate a headlamp in the helmet or something like that.

Penlight style flashlights were included on the missions:

There was (is?) also a replica- Barbolight Apollo.

This.

If I were stuck in an airtight metal tube out in space, the last thing I would want to worry about is my lithium ion powered flashlight exploding and venting toxic gas all over. I’d definitely want Intrinsically Safe. And no lithium ion battery.

I wonder what lights taikonauts use? SpaceFire? NiteStars?

All I can say is if Bezos used an astrolux flashlight in space, astrolux sales would go through the roof.

Do you think a flashlight could even work in space?

There is no atmosphere in space—its vacuum and no sound waves can be heard or travel; and there is no gravity, its just black space with nothing there, no particles or waves to carry a light beam. You could push the button but nothing would happen… Grad

I prefer to use the saying; Sales would be sky high. Big Smile
