If You Could See Satellites, What Would The Sky Look Like

newtboy says...

What does he mean "if" I could see satellites? Where I live, on clear nights I've been able to watch the international space station be supplied....I could see both the station and the resupply capsule all the way to docking, as well as multiple other satellites.

How to FLY A SPACESHIP to the SPACE STATION

CRS-6 First Stage landing attempt

oritteropo says...

SpaceX has released footage of the April 14 landing attempt from the CRS-6 First Stage Tracking Cam:



Footage from a tracking camera that followed the first-stage of the Falcon 9 during a landing attempt. The footage starts at about 10 km in altitude. Falcon 9 first stage approached the drone ship “Just Read the Instructions” in the Atlantic Ocean after successfully launching the Dragon spacecraft during the CRS-6 mission to the International Space Station on April 14. More info:

Post-launch analysis has confirmed the throttle valve as the sole cause of this hard landing. The team has made changes to help prevent, and be able to rapidly recover from, similar issues for the next attempt, which will be on our next launch—the eighth Falcon 9 and Dragon cargo mission to the space station, currently scheduled for this Sunday.

Blackout City

newtboy says...

Where I live, in the boondocks of N Cal., we usually have a few days of power outage a year. On those rare occasions when there's an outage and a clear sky, we get to see this. There's nothing like sitting in your hot tub, looking up at the night sky FULL of stars, and watching the international space station get re-supplied, and noticing how many satellites cross it's path every orbit. I feel like we should have at least one 'blackout' night per year worldwide, where we do our best to not use outdoor lights in an effort to show this beautiful expanse of nature to those who never get to see it.

3D Display Projects Images Into Mid-Air (No Screen)

newtboy says...

My thought was actually to have multiple projectors per block approximately 10 feet up (building mounted) with sensors to identify people and have them 'place' a smallish ball of light at about 8-10 feet up that floats above and in front of them, but with much less light needed than a 'street light'...and maybe stationary one's in intersections (these could even have 'covers' to stop wasted light from going up). Or, it could project tiny lights (like in the video) near ground level to illuminate the sidewalk, but that's not as useful by far.
By my estimation, there could be less pollution because there would be fewer, smaller lights on at any one time (where normal lights are just ON all night). I agree, there are many issues to solve, but it's doable if thought about thoroughly.
It's a little too late to worry about 'light pollution'...in fact I bet it's not on the average person's radar. Sadly, many people in cities have never seen stars at night and don't have a clue how much is hidden from them. (I live in the boonies of far N cali, and we still have light pollution from nearby towns, but nothing like in a city...I've even watched the international space station get re-supplied while sitting in my hot tub! That was amazing!).

Yeah, but I'm not going to do any of these. I'd never in a million years even think about this, never mind do any tests. Yet here I am, a few clicks and I've seen it all.

Another reason why Mitt Romney will not be President

lantern53 says...

A stack of $100 dollar bills totaling one trillion dollars will make a pile 568 miles high...that is twice the height of the International Space Station. Since Obama came into office, we have 15 of those piles of cash.

Four more years of Mr. Obama will bury us all...in debt.

Mr. Romney, of course, has a record of financial responsibility, but you don't like him for...whatever your reasons are.
