As events unfold, it appears that the Vision for Space Exploration (VSE), the President's plan to return humans to the Moon and then onto Mars, is on the classic pride-before-the-fall trajectory. In the spirit of collegial exchanges, I offer the following observations and thoughts for our recovery. To my fellow rocket scientists and space enthusiasts, the time has come let go of last century's space dreams and start working toward a more contemporary future.

SpaceX Announces Falcon 1 Launch Date |

El Segundo, CA – November 18, 2005 – On Friday, November 25 at 1 p.m. (PDT), the Falcon 1 countdown to launch is expected to reach T-Zero. At that point, the hold-down clamps will release and the Falcon 1 rocket will begin its journey to orbit, accelerating to 17,000 mph (twenty-five times the speed of sound) in less than ten minutes. Designed from the ground up by SpaceX, Falcon 1 is a two stage rocket powered by liquid oxygen and purified, rocket grade kerosene. On launch day, Falcon 1 will make history for several reasons: * It will be the first privately developed, liquid fueled rocket to reach orbit and the world's first all new orbital rocket in over a decade. * The main engine of Falcon 1 (Merlin) will be the first all new American hydrocarbon booster engine to be flown in forty years and only the second new American booster engine of any kind in twenty-five years. * The Falcon 1 is the only rocket flying 21 st century avionics, which require a small fraction of the power and mass of other systems. * It will be the world's only semi-reusable orbital rocket apart from the Shuttle (all other launch vehicles are completely expendable). * Most importantly, Falcon 1, priced at $6.7 million, will provide the lowest cost per flight to orbit of any launch vehicle in the world, despite receiving a design reliability rating equivalent to that of the best launch vehicles currently flying in the United States. The maiden flight will take place from the Kwajalein Atoll of the Marshall Islands. The customer for this mission is DARPA and the Air Force and the payload will be FalconSat-2, part of the Air Force Academy’s satellite program that will measure space plasma phenomena, which can adversely affect space-based communications, including GPS and other civil and military communications. The target orbit is 400 km X 500 km (just above the International Space Station) at an inclination of 39 degrees.

Are you looking for some help with a science fair project? If so, then you have come to the right place. The IPL will guide you to a variety of web site resources, leading you through the necessary steps to successfully complete a science experiment. If you have never done a science fair project before, it has been a while, or you just want to be sure you do a really great job be sure and look at the following websites for tips on what makes a good project before doing anything else. This way you will know ahead of time what will be expected of you.
I was helping a young friend come up with an idea for a science fair project, and this site looks like a great resource. Internet Public Library: Science Fair Project Resource Guide |

After some generalized comments by Scott Pace, John Connolly presented an overview of the new launch systems and spacecraft that will be used to return American astronauts to the Moon. Much of what Connolly presented had been released with the announcement of the results of the Exploration Systems Architecture Study (ESAS). However he added new details previously not presented - and offered briefing charts which went into even greater detail.

The White House has approved NASA's ESAS and it will be unveiled publicly on Monday at NASA HQ. As to what it will look like: think Apollo - both for what it will feature - and what it will not feature - as well as how things will look- and how they will work. Mars is only a footnote - a distant one at that.
They just can't seem to get it right, can they? Rollout Plan for Griffin's Architecture Gains Momentum | NASA Watch |

Let's not forget that NASA is a particular form of Govt. bureaucracy that takes its lead from directives from the Executive Branch but gets the actual means to do so from the Legislative. All snarkiness aside, Feynman was spot on during the 51-L investigation. He didn't "play nice" like some commissioners, and called it like he saw it. I will always give the Shuttle program its due: it is/was a magnificent machine designed under the most schitzophrenic critera of any major engineering project ever. However, the levels of complacency that (IMO) will always exist among cloistered groups of engineers, managers and technicians when they work inside "the only game in town". It took someone like Feynman to call "Bullshit!" on the intellectual lethargy that grows around such stagnant systems.
