Nasa's Lunar Reconnaissance Orbiter is now in a 50km-high orbit around the Moon and has been able to resolve Apollo 17 hardware. The image shows the descent stage left on the Moon's surface by Jack Schmitt's and Gene Cernan's Lunar Module. Even the flag they planted is just visible.

Do you mean they really landed? :D.

It's fake...because the flag looks like it's too far away from the craft compared to the other photos...hehe :D

Some will take it as proof that man landed on the Moon, some will take it as proof NASA has Photoshop...

Suck it conspiracy theorists :twak:.

Last week I went to the "new" Air and Space Museum last week (a HUGE hanger by the airport). An awesome side trip for anyone visiting the D.C. area.

That's the quote of the day!

I haven't seen the Air and Space Museum since '88, would love to get back up there.

Very cool photo indeed!

I am still trying to figure out why NASA is scared to death to land on the moon again. They must be if the deleted their records of being there right? I think they found something and don't want the public to know about it.
Thats my one and only dig at the government, its best to stop before dark suits knock on the door.:D

NASA is not scared to go to the Moon. Our government is scared to finance it.

I have a female friend that attended an official lecture with one of the guys that took place in that old space travel. She is a very sharp business woman with loads of skepticism against "conspiracies" but afterwards she told me that it was one thing that made her start think.

The Astronaut said that the computer that did run the whole process officially included less information than a modern digital clock. The Astronaut gladely announced it because he pronounced it as a heroic challenge with a small computer like this.

My female friend said that it most possibly wouldnīt be realistic to manage the gigantic forces it craves to start, land and navigate back to earth with a minimal computer like that.

I havenīt got a clue if itīs realistic or not but the more I read the more skeptical I get!

Their records weren't deleted. The one original tape of the recorded video of the landing was either accidently erased or someone just took it home. There were backups made before hand though, and those are fine.

Before that they worked it all out on paper. It's just math.

The computers were puny by today's standards, but top of the line then. It's not as if they were AI autopilots, they were just calculators and timers.

I can't believe that some people, right here on this forum, as intelligent as they are, wonder if Neil Armstrong, Buzz Aldrin, Pete Conrad, Alan Bean, Alan Shepard, Edgar Mitchell, David Scott, James Irwin, John W. Young, Charles Duke, Eugene Cernan and Harrison Schmitt really walked on the moon.

Geez!

It's funny some of those craters look like they have spider webs coming off of them. Almost like it's the lights from some civilization, branching out from some central city core.

Huh, I could have sworn they said on the news that the entire data from the computer was deleted. I don't even recall which broadcaster had that segment.

But my memory is bad so I'll leave it alone, as I could easily be wrong. been there, done that. :D

There are also printed copies of that data, back then paper still ruled. Reams and reams of folded computer paper with the little holes on the edges. That they probably will get rid of one day.

that computer was for guidence..the onboard back ups were the astronaughts, pen, paper and their slide rules...remember slide rules?...naah though not...

http://en.wikipedia.org/wiki/Slide_rule

The slide rule, a mechanical analog computer. The slide rule is used primarily for multiplication and division, and also for "scientific" functions such as roots, logarithms and trigonometry, but is not normally used for addition or subtraction.

Slide rules come in a diverse range of styles and generally appear in a linear or circular form with a standardized set of markings (scales) essential to performing mathematical computations. Slide rules manufactured for specialized fields such as aviation or finance typically feature additional scales that aid in calculations common to that field.

William Oughtred and others developed the slide rule in the 1600s based on the emerging work on logarithms by John Napier. Before the advent of the pocket calculator, it was the most commonly used calculation tool in science and engineering. The use of slide rules continued to grow through the 1950s and 1960s even as digital computing devices were being gradually introduced; but around 1974 the electronic scientific calculator made it largely obsolete and most suppliers exited the business.

if you have an iphone there's a a slide rule app!:D

or MAKE one in lightwave!

last time i used a slide rule would be in early 70's...
then my older brother bought a texas instrument calculator! whooo hooo!..LED display!

here's a flash based circular one

If you try the root of 4, then you get 1.99 :D.

do you remember the early pentium chips that had a calc error in them?:)

slide rules don't do to huge decimal places...they were the besot of that time seeing as hand held electonic calculators were yet to be invented!:hey:
