I think it was only about the first lunar landing by US. Was it real?shrey said:hell people even said man never went to the moon![]()

Okay, then why dont they just send someone back to moon after all these years..its as if they have abruptly terminated the moon program after they thought tht the bubble was about the burst..? If they had the technology then, why cant they do it now when the technology has leaped forward a hundred thousand times since then..?? Nasa guys reportedly said tht it'll take upto 2015 to go back to moon..why?? when they cud go there in the shoddy space shuttles in 1969?? and not only tht, they supposedly went there many times thru the 70s till the public lost interest.. Is it the fear of the media which has matured beyond control and its hard to hide facts nowadays from prying eyes of the world outside??
Kumar said:Quiet simply 1 reason.....there is no use sending manned missions to the moon now.The moon landings were done in the heat of the cold war when there was break neck competetion with USSR.
Kumar said:Another reason for not sending manned missions is that the same objectives can be achieved by using robots.no use risking humans on relatively trivial missions.
Kumar said:the technology may have advanced hugely now but that may not necessaryly reflect in the amount of time/effort it takes to undertake a task of this proportion.
Yaar, dont u think its a very lame reason..to cover up incapabilities??
Was Human life not so important then as it is now?? n didnt they send unmanned probes then which were essentially robots
Definitely yes..but this equation was there even then in 1969..infact with their limited technological prowess then, they were at a lot more risk to loose it all then..than now when the risks of technological failure are much less than it was in 69... And why does NASA say tht they cannot send a man 'back' to moon b4 2015 because of complexities..well, as if it were a cake walk in 70s?
Err..correction..Man never really went to the moon..you need to watch tht Fox news vdo..the theories given which prove tht man never went to the moon are so strong tht u are hard pressed to believe it..but why go far..we've got a thread here in TE itself..was just searchin somethin n came upon this one..interesting read..check it out..Do you believe that Apollo moon mission was a hoax ?

Not every waving flag needs a breeze -- at least not in space. When astronauts were planting the flagpole they rotated it back and forth to better penetrate the lunar soil (anyone who's set a blunt tent-post will know how this works). So of course the flag waved! Unfurling a piece of rolled-up cloth with stored angular momentum will naturally result in waves and ripples -- no breeze required!

No crater should be expected. The Descent Propulsion System was throttled very far down during the final stages of landing. The Lunar Module was no longer rapidly decelerating, so the descent engine only had to support the module's own weight, which by then was greatly diminished by the near exhaustion of the descent propellants, and the Moon's lower gravity. At the time of landing, the engine's thrust divided by the cross-sectional area of the engine bell is only about 10 kilopascals (1.5 PSI)[11], p. 164, and that is reduced by the fact that the engine was in a vacuum, causing the exhaust to spread out. (By contrast, the thrust of the first stage of the Saturn V was 3.2 MPa (459 PSI), over the area of the engine bell.) Rocket exhaust gases expand much more rapidly after leaving the engine nozzle in a vacuum than in an atmosphere. The effect of an atmosphere on rocket plumes can be easily seen in launches from Earth; as the rocket rises through the thinning atmosphere, the exhaust plumes broaden very noticeably. Rocket engines designed for vacuum operation have longer bells than those designed for use at the Earth's surface, but they still cannot prevent this spreading. The Lunar Module's exhaust gases therefore expanded rapidly well beyond the landing site. Even if they hadn't, a simple calculation will show that the pressure at the end of the descent engine bell was much too low to carve out a crater. However, the descent engines did scatter a considerable amount of very fine surface dust as seen in 16mm movies of each landing, and as Neil Armstrong said as the landing neared ("...kicking up some dust..."). This significantly impaired visibility in the final stages of landing, and many mission commanders commented on it. Photographs do show slightly disturbed dust beneath the descent engine. And finally, the landers were generally moving horizontally as well as vertically until right before landing, so the exhaust would not be focused on any one surface spot for very long, and the compactness of the lunar soil below a thin surface layer of dust also make it virtually impossible for the descent engine to blast out a "crater"
