It's Official - Moon Return is a No Go





In an article by the Washington (AP), the White House panel on NASA's return-to-the-moon plan will not happen at current funding levels. Current NASA's budget is $18 billion per year. It would require an additional $3 billion to go back to the moon by 2020.

And thats with retiring the shuttle in 2010 and shutting down the International Space Station in 2015 (which would be very stupid since we just spent the better part of 20 years building the damn thing!).

The panel suggested the following, "Space exploration would work better by including other countries and private for-profit firms." They also suggested that if NASA continues its current moon plans, in order to save money, it should kill plans to make a smaller Aries I rocket to carry astronauts and go right to the bigger Aries V."

$7.7 billion have already been spent on the Aries I so far and a test of its first stage is about to take place soon. A test launch may even happen by Halloween.

NASA Renegades and the Jupiter Direct System


Been hearing about this fable NASA Engineers underground for awhile now. Renegades who have come up with a better design system for the space shuttle replacement than the establishment's Aries series of rockets. Currently referred to as the Jupiter 120 or the follow-on Jupiter 232 (Jupiter Direct). In fact, the Jupiter 232 would have more “throw” weight that the planned Aries V rocket. And all this with using more of the shuttle hardware and current generation of Solid Rocket Boosters (SRB) used in the shuttle program. And if given financial approval by spring of 2009, the first Jupiter could be ready for launch by 2013. Thus – there would only be a three year gab in U.S. Manned spaceflight operations instead of the currently planned five year gap. After reading the article in the latest Popular Mechanics (February 2009), I visited the website and joined up there to get more information.


Then again, the “Jupiter” project is the latest version ever since the space shuttle first flew of various launch vehicles that could launch heavier payloads than the shuttle could. EELV anybody?


So, now we have the Orion/Aries system and it seems like everybody except the bureaucrats in the NASA headquarters have complaints about the design of the Aries. Instead of using a regular Solid Rocket Booster(SRB), they added another fifth segment to create the Aries I, or as it was referred to on the website, “The Stick.” Instead of re-using the main engines off the shuttle, the J-2X would have to be developed and man-rated for the second stage booster.


The argument that I am seeing is that we should go with the Jupiter Direct over the Aries system and I am all for that. But knowing that the fix is in Washington D.C., that is not going to happen. They got their blinders on and logic is not going to change their minds.


So, what else is new with Washington?
