NASA's proposed Ares rocket is supposed to replace the space shuttles and eventually fly astronauts to the moon. But the White House may scrap that plan. In the meantime, the space agency is considering additional flight tests, possibly in 2012 or 2013. The first manned flight of the Ares I rocket is targeted for 2015.

I remain in awe over how NASA succeeds so well in their REAL endeavour: to have most people believe in their utter bullshit stories.

The vehicle's first stage ignited at T-0 seconds and Ares I-X lifted off from Launch Complex 39B.[17] The first stage separated from the upper stage simulator and parachuted into the Atlantic Ocean roughly 150 miles (240 km) downrange of the launch site. The maximum altitude of the rocket was not immediately known, but had been expected to be 28 miles (45 km).
The launch accomplished all primary test objectives,[18] and many lessons were learned in preparing and launching a new vehicle from Kennedy Space Center.[19]

Any guidance as to what I'm doing wrong would be great. Thanks

Dr. De Lee Forest known as the "Father of Electronics" predicted that man wouldn’t ever even reach the moon let alone travel by rocket ship to strange worlds in distant galaxies
Man, declared De forest is inherently an earthly creature, and only his scientific imagination will make him ever a planetary emigrant
De forest invented the vacuum tube 51 years ago and that made possible the development of modern radio broadcasting, television and radar.
His observations of the future were broadcast Sunday by The Voice of America, the State Department Overseas information program
Sees Transoceanic TV.
De Forest forecast transoceanic television within ten years. He said this could be accomplished by skillful location of relay stations and by taking advantage of reflection of television waves from the ionosphere, the layer of electrical energy that surrounds the earth at a great height
But I am much more conservative in the estimate of interspace flight De Forest said
“But to place a man in a multistage rocket and project him into the controlling gravitational field of the moon, where the passenger can make scientific observations. Perhaps land alive, and then return to earth -- all that constitutes a wild dream worthy of Jules Verne” , he said adding
“I am old enough to say that such a man made moon voyage will never occur regardless of all scientific advances
Well not that i disagree, but I would love to read the actual arguments in support of these statements rather than just the statements themselves. Is there a source to this? Is it all here or there's more? Where this is taken from?


wikipedia wrote:Mechanical problems in early satellites were sometimes attributed to cold welding. However, in 2006, Henry Spencer stated that the phenomenon of spontaneous cold welding in outer space is "basically a myth", pointing out that "there are no documented cases of it actually occurring in orbit, except in experiments deliberately designed to provoke it (with susceptible materials, great care to avoid contamination, and deliberate mechanical removal of oxide layers, etc.)."[3]
Three years following this 2006 post the European Space Agency published a peer reviewed paper detailing why cold welding is a significant issue that spacecraft designers need to carefully consider. The conclusions of this appropriately titled study can be found on page 25 of "Assessment of Cold Welding between Separable Contact Surfaces due to Impact and Fretting under Vacuum". The paper also cites a documented example from 1991 with the Galileo spacecraft high-gain antenna (see page 2; the technical source document from NASA regarding the Galileo spacecraft is also provided in a link here). [4] [5]
One source of difficulty is that cold welding does not exclude relative motion between the surfaces that are to be joined. This allows the broadly defined notions of galling, fretting, sticking, stiction and adhesion to overlap in some instances. For example, it is possible for a joint to be the result of both cold (or "vacuum") welding and galling (and/or fretting and/or impact). Galling and cold welding, therefore, are not mutually exclusive.

One of the hazards of space travel is a phenomenon known as cold welding. The vacuum of space causes metal to stick together, a tendency that could be catastrophic in a space craft.

A cold-welding program was initiated in 1969 to determine
the proper test environment for qualifying spacecraft

That IS an interesting find, Hollycrap. I also found this 1972 NASA Technical report called Cold- Welding Test Environment. Let me just quote these few lines of the report:

Now, without the need to be a rocket scientist, one must ask oneself: if tests of such crucial technical importance were only INITITIATED as late as 1969 - how on Earth did they land Apollo11 on the moon that very same year?
