NASA used to shed every ounce of weight the could to maximize the amount of rocks they could bring back. Even going so far as leaving their trash and bags of human waste (poop) behind on the moon. So this camera is really rare to have been brought back.

Key point to add about this. The search doesn't end because we find one planet that looks a bit like Earth. It keeps going. We will always look to the stars and try and see what is out there. We may not be able to go to these places right now or send a probe in a reasonable time frame but knowing that there are more…

This is so cool. Would guess they only had this up for one day. Give it more that a day and someone would steal the entire rig.

Short service life is countered by the super cheap cost vs launching a satellite into orbit. Once a sat is in orbit it's a done deal whether it works or fails. This thing can return to an operating location to get repaired or refitted with new guts and keep on flying. It has a smaller area of view (operations area)…

So I read this that the Starshade is really an independent spacecraft. If it can work with other "pre-existing telescopes." It will also need some high end clever piloting software to get the two craft to work together correctly. It's pretty cool looking though.

I drove to Stonehenge a couple times when I lived in the UK. This photo is from the place where you get the first glimpse of it and the scene here with the carvan and all the cars is just how I remember it.

Yup! Stardust's collector was a very cool idea to catch particles from a comet!

It's Lex Luthor's place, that is why you can't find it.

Just wow! I'm upset that my firewall at work blocks the full video. I have heard of dynamiting a river to get it flowing and would have assumed that would be cheaper and safer to do than all this. It's pretty cool though too. I bet those bombs impacted the river floor before they went off so maybe they were…

If my office only had a decent plotter printer I would have already had this one on my office wall too.

Billions and billions of laughs. The Cosmos is full of amazing so many wonderful things.

DC-3's were hugely popular aircraft for commercial and cargo transport during and right after WWII. It was a twin prop plane that flew under and in the weather. Jets were pressurized and flew above most of the weather and this gave them a big advantage. I'm not surprised by this plane being the highest count of…

I travel to Las Vegas to work at Nellis quite a bit throughout the year. There is rarely a dull moment if you like seeing cool aircraft flying. The Thunderbirds just got their certification for this years tour a couple weeks ago when I was there. Same week I saw a whole list of planes flying from F-22, F-23, A-10,…

The hole adds drag which probably did affect wing performance a bit. It's far enough back though it was not in a critical spot for the air flow. Wings are built tough but also worth noting if the wind is high enough in the opening it can add pressure to other panels and break them as well which might then really…

Been following these guys for a while now. Very impressive system and they live stream all of the tests. Check them out.

Yup that was pointed out by someone else on the other post. Off axis aiming and firing is tough to do so you almost have to be standing right behind it to get a good shot off. They really could have made it a bit more fun in fights if they added a target to it that would act as a kill switch that would let other…

The fact that we can spot as many as we do is a huge improvement over the 0% we could spot in 1995 when the Near Earth Object (NEO) program first ramped up. 10,713 objects have now been spotted and of those 1,457 potentially dangerous ones are now being watched more closely. Spot a bad one too late and we got 0% of…

Go ahead and post it again then please.

I love how there is no terror at all on this guy. Just a "hang on a sec," kind of reaction. Almost expect him to just turn around in the next frame and keep on talking like nothing had happened.

Here is a WAC Corporal rocket. I can imagine the head scratching when someone first came up with the idea of putting one of these on the top of a V-2
