JFK - We choose to go to the Moon, full length "We choose to go to the Moon" As we sit at the precipice of a new era of exploration, I thought it would be appropriate to revisit the original inspiration and rational for the first lunar exploration program as so eloquently stated by John F. Kennedy. The original speech by JFK was held in Houston, TX at the Rice Stadium in the fall of 1962. "Many years ago the great British explorer George Mallory, who was to die on Mount Everest, was asked why did he want to climb it. He said, 'Because it is there.' Well, space is there, and we're going to climb it, and the moon and the planets are there, and new hopes for knowledge and peace are there. And, therefore, as we set sail we ask God's blessing on the most hazardous and dangerous and greatest adventure on which man has ever embarked." -John F. Kennedy, Rice University, Sept. 12, 1962 http://www.jfklibrary.org/Historical+Resources/Archives/Reference+Desk/Speeches/JFK/003POF03SpaceEffort09121962.htm http://en.wikisource.org/wiki/We_choose_to_go_to_the_moon http://www.nasa.gov/mission_pages/constellation/main/index.html www.rice.edu www.nasa.gov Tags: JFK NASA moon lunar speech mercury gemini apollo naca space russian race cold war rice houston John Kennedy |

VASIMR Ground Testing This is a series of test firings of the VASIMR VX-200 plasma rocket prototype. The rocket's 1st stage (a Helicon plasma source) was fired at 14 kW using a solid state RF amplifier, and argon gas as the propellant. The video is slowed down to half speed. The VX-200 is designed to use 30 kW for its first stage and 70 kW for its second stage (an ion cyclotron heating stage). The VX-200 is the precursor to the VF-200, a flight demonstration unit that is intended to fly on the International Space Station (ISS).

Lunar Tug Using Plasma Rocket An unmanned cargo capability based on VASIMR propulsion offers significant cost savings to NASA and commercial lunar exploration programs. VASIMR can deliver twice as much payload to the lunar surface, compared to chemical propulsion, if used as a 'tug boat' between Low Earth Orbit and Low Lunar Orbit. At the present, chemical propulsion always has to be used to climb out of Earth's atmosphere and into a Low Earth Orbit, in addition to the final lunar landing descent. Beyond VX-200 (VASIMR Experimental, 200 kW) and VF-200 (VASIMR Flight, 200 kW) demonstrations, the Ad Astra Rocket Company plans to fill a developing high power transportation niche near Earth for orbit maintenance of large space structures for commerce and tourism and satellite repositioning, retrieval and re supply. Longer term applications for which VASIMR may be ideally suited include: the delivery of large payloads to the lunar surface, recovery of space resources from asteroids and comets and propelling cargo and human missions to Mars and beyond.

Q&A with Dr. Jack Schmitt, Apollo 17, NASA Advisory Council In this pre-lecture Q&A Dr. Harrison 'Jack' Schmitt shares his thoughts on the future of space travel, what his family thought of his profession as an astronaut, and his experiences from Apollo 17. Return to the Moon: What it was like and will be like! -Dr. Harrison 'Jack' Schmitt A view of Apollo 17 in the context of what is left to learn and accomplish on the Moon with an eye to science, settlement, and providing energy for the Earth. At the Space Center Lecture Series on March 13,2008 Dr. Schmitt shared his experience with the Apollo 17 mission, lunar resource utilization, and his thoughts on the future of lunar science and exploration. The Apollo 17 mission was the last of the great campaigns to the moon and included the longest lunar surface interval of any mission in history. Don't miss Jack's exciting tales of past lunar exploration and future plans to Return to the Moon. The Space Center Lecture Series was co-founded and is co-hosted by Dr. Benjamin Longmier and Mr. Gary Kitmacher.

Breathing Xenon Breathing Xenon: Xenon is the heaviest non-radioactive noble gas (5x density of air) and is used for ion thrusters, general anesthetic, and various types of lighting sources. http://en.wikipedia.org/wiki/Xenon Xenon's anesthetic effect is 1.5 times more potent than N2O. Please do not breath Xenon without proper medical supervision and supplemental oxygen. "The anesthetic effect of inert gas xenon (Xe) was discovered more than 50 years ago. The main causes limiting its clinical application are high price, low availability (in nature the gas is present in scarce amounts), and absence of preclinical trials sufficient for norm-setting documents and further solutions allowing clinical trials of Xe." http://www.expresshealthcaremgmt.com/20050515/criticare10.shtml "These are the heaviest of the inert gases, and have some peculiarities. Xenon is, amazingly, an anaesthetic, in spite of the fact that it is inert. This is not completely explained, but is supposed to be associated with the strange behavior of xenon and water. 46 water molecules can hydrogen-bond themselves into a complex molecule with icosahedral symmetry that forms eight "cages" of the right size to accommodate xenon atoms, stabilized by dispersion forces between the xenon and the water. This 8Xe•46H2O is called a clathrate, from the Greek for a cage. Eight methane molecules can take the place of eight xenon atoms, to form an ice-like methane hydrate that can block pipe lines even at temperatures well above 0°C. Possibly the xenon encourages the formation of such clathrates in the brain, and the other smaller cages that are formed can clathrate ions important in brain function. For more information on gas hydrates, see Hydrates.

Jack has some trouble as he tries to pick up a lunar rock sample bag and stand up at the same time. The Apollo EVA suits had a weight of 60lbs on the Moon and were a little top heavy.

Falling on the Moon Jack Schmitt falls while trying to pick up a lunar collection kit. In his defense, the lunar EVA suit was top heavy and it was quite difficult to bend down to pick something up from the ground.

Hammer throw on the Moon Jack Schmitt throws his geology hammer in the 1/6 lunar gravity before they get back inside the lunar lander. Hammer can be seen going nearly strait up above Jack and then falls off to the left and descends behind the LM. The rover is parked at the VIP site behind the lunar module. Jack emerges as a small figure, 145 meters away, to the right of the lunar module. He pleads with Gene to let him throw his geology hammer. The commander concedes his permission and warns him not to hit the lunar module or the ALSEP. Jack flings it into the air and careful observation of the clip reveals the spinning hammer in flight, barely visible against the mountain in the background, and then against the black sky. Jack is thrilled with the long flight of the hammer and walks back to the lunar module. Tags: moon apollo 17 hammer throw olympics nasa geology long space |

Fixing lunar rover with duct tape Gene Cernan fixes a rear fender on the lunar rover during Apollo 17. Apparently, good ol' duct tape was the procedure for fixing such a problem. Without the fender Jack Schmitt was sprayed with dust. Gene works to repair the rover's broken fender while Jack reaches the ALSEP site. The clip opens to show Gene tearing off a strip of duct tape from a roll and applying it to the fender. Jack asks Bob Parker if they can see him and Bob says "No," but a voice from the back room in Houston points out that he has just appeared at the left of the picture as a white spot in the distance. The EVA controller advises the flight director that Gene is now twenty minutes behind in his timeline. The camera leaves Gene at the rover and zooms to find Jack resting and evaluating his chosen ALSEP site area, the experiments package beside him on the ground. He discusses the site with the capcom, who informs him he is ten minutes behind in his time line. He picks up the ALSEP, moves it a few meters to his left, discusses experiment placement requirements with Bob, and the back room Experiments team reacts to his questions and remarks. http://en.wikipedia.org/wiki/Duct_tape Picture of the final product http://en.wikipedia.org/wiki/Image:Duct_tape_apollo17.jpg Tags: fixing lunar rover with duck duct tape repair car truck buggy moon nasa apollo 17 gene cernan jack schmitt |
