PROJECT REDSUN: THEY WENT TO MARS WITHOUT TELLING US

[guohua]

OK so how did they get to Mars and Back From mars?
The First Orion Spacecraft.
 

Project Orion was a study of a spacecraft intended to be directly propelled by a series of explosions of atomic bombs behind the craft (nuclear pulse propulsion). Early versions of this vehicle were proposed to take off from the ground with significant associated nuclear fallout; later versions were presented for use only in space.

The Orion concept offered high thrust and high specific impulse, or propellant efficiency, at the same time. The unprecedented extreme power requirements for doing so would be met by nuclear explosions, of such power relative to the vehicle's mass as to be survived only by using external detonations without attempting to contain them in internal structures.
As a qualitative comparison, traditional chemical rockets—such as the Saturn V that took the Apollo program to the Moon—produce high thrust with low specific impulse, whereas electric ion engines produce a small amount of thrust very efficiently.
Orion would have offered performance greater than the most advanced conventional or nuclear rocket engines then under consideration. Supporters of Project Orion felt that it had potential for cheap interplanetary travel, but it lost political approval over concerns with fallout from its propulsion.

The Partial Test Ban Treaty of 1963 is generally acknowledged to have ended the project. However, from Project Longshot to Project Daedalus, Mini-Mag Orion, and other proposals which reach engineering analysis at the level of considering thermal power dissipation, the principle of external nuclear pulse propulsion to maximize survivable power has remained common among serious concepts for interstellar flight without external power beaming and for very high-performance interplanetary flight.

Yes we could have gone to Mars and Returned with no Problem of Needed to Refuel Like Chemical Rockets.

The first people to step on to the surface of Mars won't arrive aboard the chemical-fueled rockets that delivered Apollo 11 to the Moon—they simply don't provide enough thrust to get to the Red Planet before exposing their crews to months of dangerous space radiation. Instead, NASA is turning to long-ignored nuclear-thermal rocket technology to deliver the first Martian explorers into history.

How NASA Built a Better Rocket
Nuclear-thermal rockets are by no means a new technology. In fact, researchers began discussing the prospect of utilizing nuclear power to propel rockets and aircraft back in 1942 after Enrico Fermi's successful fission reactor tests. By 1944 teams at the University of Chicago's Metallurgical Laboratory and Los Alamos National Lab developed an early nuclear-thermal design that used a fission reactor to super-heat hydrogen gas which would then escape through a small nozzle to generate thrust. Since nuclear fuel is about 107 times more energy dense than their chemical counterparts and similarly powerful rockets would weigh only about half as much, nuclear-thermal rockets (NTRs) can carry load to fuel ratios from 1:1 to as high as 7:1 especially when used as the upper stage. This design piqued the interest of the US Air Force, which conducted highly-classified testing at Oak Ridge National Labs between 1947 and 1949.

NASA's side, Project NERVA (Nuclear Engine for Rocket Vehicle Applications), was specifically tasked with creating a space-worthy, mission-deployable, and—most importantly—real nuclear-thermal star ship engine. The more than 20 distinct rocket designs produced in this 17 year span constituted numerous design phases: the Kiwi, an aptly-named early design never intended for flight developed between 1955 and 1964; the larger, intermediate Phoebus design developed from 1964 to 1969; and the Pewee, which ran from 1970 to 1971 until they were replaced by the nuclear furnace design. The NRX (Nuclear Rocket Experimental) series saw concurrent develop with the Phoebus and Pewee platforms from 1964 to 1968.

Another offshoot of the original KIWI designs was the NERVA NRX (Nuclear Rocket, Experimental), which began testing in 1964 and evolved into the NERVA NRX/XE—a nuclear rocket tantalyzingly close to flight readiness. The SNPO tested the XE engine a total of 28 times in 1968, firing it downward into a low pressure chamber to crudely mimic the effects of space's vacuum. Every test, the engine generated over 1100MW of energy as well as 75,000 lbf (334 kN) of thrust—the baseline output the SNPO had demanded Marshall meet before authorizing a RIFT launch as well as the amount the agency needed to effectively get astronauts to Mars. 
During testing, the engine ran for over two hours in total, 28 minutes of which at full power, and typically only stopped when they burned through all 38 pounds of fuel.

Yes full power, only 38 pounds of Fuel!

This success, in combination with Los Alamos resolving three niggling materials issues, spawned a whole menagerie of potential uses for the new nuclear-powered rockets. Some wanted them to replace the J-2 boosters used of the second and fourth stages of Saturn I and IV. Others wanted them utilized as "space tugs," towing objects from LEO to the upper orbital tracts, the moon, and further.
Unfortunately, none of these ideas ever got off the drawing board because the entire project was cancelled at the end on 1972, effective spring 1973.

Was it cancelled?

How Nuclear Thermal Rockets Work
All of the Rover/NERVA rockets ran on Plutonium-238, a non-fissible isotope with a half-life of 88 years. With such a short half-life and the relative difficulty of separating the specific isotopes from the clumps of naturally-occurring plutonium, Pu-238 is typically synthesized using the same method originally employed by Berkely Lab researchers Glenn T. Seaborg and Edwin McMillan in 1940—bombard a sample of Uranium-238 with deuterons.

Plutonium-238 is a valuable commodity for deep space exploration where insufficient amounts of sunlight render solar panels useless.

NASA's radioisotope thermoelectric generators (RTG) that most of power these missions instead run on a nugget of Pu-238. While plutonium is a poor conductor of electricity, its emission of alpha particles as part of its decay process generates a terrific amount of heat to run the RTGs. The famous Voyager probes, the Cassini spacecraft, the Curiosity Rover, and the New Horizon's probe all rely on nuclear power for their continued operation.

Now in 1993, You have to listen to the Video and hear what the Head of The Lockheed Skunks Works Division Says.

MUFON International Director Jan Harzan talks to me about his personal experience with fellow alumnus Ben Rich, former President and CEO of the Lockheed Skunkworks. "We now have the technology to take ET home." This a must see for anyone who doesn't think faster-than-light travel is possible, or harbors any doubt that we don't already know how to do it. Of course, for Mr. Shermer and the other paid, propaganda ministers at "Skeptic" Magazine, it IS just a story...right?

Extraterrestrial UFO Are Real : Ben Rich Lockheed Skunk Works Director Admitted In His Deathbed Confession

Ben Rich Lockheed Skunk Works director had admitted in his Deathbed Confession that Extraterrestrial UFO visitors are real and the U.S. Military travel among stars.

According to article published in May 2010 issue of the Mufon UFO Journal [Link] - Ben Rich, the “Father of the Stealth Fighter-Bomber” and former head of Lockheed Skunk Works,had once let out information about Extraterrestrial UFO Visitors Are Real And U.S. Military Travel To Stars

What he said might be new to many people today, but he revealed the information before his death in January 1995. His statements helped to give credence to reports that the U.S. military has been flying vehicles that mimic alien craft.

The article was written by Tom Keller, an aerospace engineer who has worked as a computer systems analyst for NASA’s Jet Propulsion Laboratory.

1 : “Inside the Skunk Works (Lockheed’s secret research and development entity), we were a small, intensely cohesive group consisting of about fifty veteran engineers and designers and a hundred or so expert machinists and shop workers. Our forte was building technologically advanced airplanes of small number and of high class for highly secret missions.”

2 : “We already have the means to travel among the stars, but these technologies are locked up in black projects, and it would take an act of God to ever get them out to benefit humanity. Anything you can imagine, we already know how to do.”

3 : “We now have the technology to take ET home. No, it won’t take someone’s lifetime to do it. There is an error in the equations. We know what it is. We now have the capability to travel to the stars. First, you have to understand that we will not get to the stars using chemical propulsion. Second, we have to devise a new propulsion technology. What we have to do is find out where Einstein went wrong.”

4 : When Rich was asked how UFO propulsion worked, he said, “Let me ask you. How does ESP work?” The questioner responded with, “All points in time and space are connected?” Rich then said, “That’s how it works!”
