keeps up on Lunar Lander Challenge news (among other things):
Not much info posted there yet. However, it’s nice to see Nvidia sponsoring a NewSpace company (this sponsorship was announced back in August). Hope more firms step up to support other entrepreneurial space projects.
The site also displays a cool Armadillo Aerospace X Prize Cup 2006 Patch
From Dave Masten to aRocket:
Ian Moore posted this just a bit ago:
As he says, we’re not competing in the XPrize Cup Vertical Rocket/Lunar Lander Challenge. 5 people and less than a year is just not enough time to put together a solid entry. This stuff is hard, especially when the head honcho is ana^h^h^h a perfectionist. 😉
We’re still planning on being at the X Prize Cup and we’re working out what if anything we’ll do there. We will most likely be showing off the XA-0.1 vehicle, and doing some looooonnnnnnnggggggg engine firings with some throttling.
Best of luck to the remaining teams, especially Armadillo.

Update: This was a great Space Show! — watch for the Podcast at Feedburner
The Tuesday, Sept. 26, 2006 Space Show from 9:30-11 AM PDT welcomes Dr. Buzz Aldrin to the show.
Dr. Edwin Eugene Aldrin, Jr. or Buzz Aldrin as he is known, was the second human to walk on the moon. On July 20, 1969, he followed Neil Armstrong onto the lunar surface while a third American astronaut, Michael Collins, remained in orbit overhead. Aldrin attended West Point, flew fighter jets in the Korean War, and then earned a doctorate in astronautics from the Massachusetts Institute of Technology (MIT) before joining the NASA astronaut corps in October of 1963. He flew on the Gemini 12 space mission (launched 11 November 1966) and then was chosen as the lunar module pilot for Apollo 11, the first manned mission to the surface of the moon. The success of Apollo 11 made Aldrin, Armstrong and Collins international heroes. Since his retirement from NASA, Aldrin has been an unabashed booster for space exploration. He founded Starcraft Boosters, a private rocket design firm. His autobiography, Return to Earth was published in 1973. He also wrote the sci-fi novels Encounter With Tiber (1996) and The Return (2000). Aldrin reached the rank of colonel in the U.S. Air Force… He reportedly got the nickname Buzz from his baby sister, who called him “buzzer” while trying to say “brother”. You can find out much more about Buzz by visiting his website, www.buzzaldrin.com.

Guests: Dr. William Gaubatz, Dr. Patricia Hynes
Dr. William Gaubatz and Dr. Patricia Hynes were the guests for this Space Show program to discuss the upcoming International Symposium on Personal Space Flight (ISPSF) and the X Prize Cup.
The ISPSF is hosted by Space Grant New Mexico and New Mexico State University and is a terrific two day conference supporting private and commercial space development. Our program discussed this symposium in detail, pointing out the quality speakers, the agenda, and some of the very fun events being planned for those attending the symposium. We then discussed X Prize Cup which takes place later in the week in Las Cruces, NM.
Both Dr. Gaubatz and Dr. Hynes shared with us not only the details of these two important events but also their importance from their unique perspectives. In addition to the discussion of these two events, listener questions were asked of Dr. Gaubatz regarding the DC-X project which he headed. You will not want to miss his discussion of DC-X.
Also, he pointed out that attending these events will afford people the opportunity to meet the current crop of historical space figures still alive, well, and working to further space development. How many of us would like to meet Goddard or Von Braun?
Well, do we want to say that about many of the greats that will be at these events? No way so we all need to show up for the opportunity to meet the founders and heroes that have taken us so far so quickly in space development. You can get more information about these two events at XPrizeCup.com.
Armadillo Aerospace Lunar Lander Challenge team leader John Carmack updates the aRocket discussion group on progress:
This is a really big video that isn’t all that exciting:
There were two issues we were concerned about right after we did this flight:
The lox pressure dropped a lot more than the fuel pressure, causing a drastic mixture ratio change, and we wound up burning some stainless from the injector at the very end, probably because with the low lox pressure not bending the unlike impinging fuel elements straight down, we got a recirculating region that we don’t get at normal pressures.
There were some attitude oscillations towards the end of the flight.
We didn’t realize it until I looked at the side view video and telemetry back at the shop, but all the problem turned out to be was that the vehicle drifted enough that it was tugging on the tether bungee cords, which caused lots of firing of the lox side roll thrusters, depleting a lot of lox ullage pressure, and also caused the oscillations. If we had been flying without tethers, we wouldn’t have seen either issue.
There was a slight drift in the integrated velocity position versus the true position over 90 seconds of about two meters, which contributed to my not realizing the exact position of the vehicle and the tethers.
The second vehicle should be getting in the air next week, and we will be trying for the 180 second flights soon.
(Oddly, no mention of Masten Space Systems… )
^ Update: 2:35 p.m. PDT — Dave Masten confessed that he did not answer his email in time to be included in the Space.com article today, but said that Masten Space Systems still plans to make a showing at X Prize Cup.
Answers by Will Pomerantz, X Prize Director of Space Projects.
Q: Will there be competitors in Lunar Lander Challenge this year?
Q: Have the rules been changed?
The rules have not been changed, although some clarifications have been made, and a few waivers for 2006 only have been issued.
Q: Have any teams received licenses or experimental permits to fly in Lunar Lander Challenge?
One of the waivers made for 2006 was to relax the timelines for teams to get their permits. This waiver was issued because the experimental permit is a brand new process for the FAA, and anticipating how long it would take them to process applications was difficult.
Q: Have any demo flights been scheduled or completed?
Some demo flights have been scheduled; however, this was also one of the requirements relaxed by waiver for 2006 only.
