Default Mars Lander history

I'm kind of obsessed with this rocket. For me it represents the golden age of rocketry. I never bought it as a kid, I thought it was too expensive/hard. As an adult I have cloned one and have 2 Semroc landers.

Does the good doctor have any insight to its development? I see from the history post that it was designed by Wayne Kellner. Can anyone fill in any information? It seems it was inspired by the LEM, and it has the Martin Marietta name on it. The urban legend when I grew up was that Estes had asked Martin Marietta to come up with a design that could be turned into realistic looking rocket, but I have never found any proof of this.

The lander is such a different rocket from anything produced at the time. With out computers it must have had a few spectacular failures before Mr. Kellner got it right.

Can the Doctor or anyone shed any light on the development of this classic?

Thanks

Mark

While you're waiting for an answer, feel free to Google "mars excursion module". Lots of reports and diagrams out there.

I cannot shed light on this one. Perhaps Matt Steele could lend a hand or possibly Roy.

wish I could, but I have no idea. I, too, was struck by how different it was from everything else that came out in '69 or for many years after.

Does anyone know if Mr. Kellner is still alive? I tried a google search, but nothing conclusive came up. Anyone know when he left Estes?

Thanks

Sorry - that was before my time at Estes as well. Ron Mclaren did the Mini-Marz Lander while we were there that was a lot of fun.

Is Semrocs' version a clone of the orig. Estes Mars Lander? If not what are the differences? I am collecting most of the 1979 Estes Catalog and the Mars Lander is not one that I was looking at collecting. I was never interested in it, and I hear it is not a good flyer. I see it on Ebay all the time going for 150.00. I spend a lot on rockets that I like and want to build but the jury is still out on this one. If I build it I may just build the Semroc version. I do agree it is a neat looking craft and someday I would like to build a scale plastic version.

Sigs30,

Carl at Semroc would be the best to answer your question, But having cloned a Mars Lander and bought 2 Semroc landers I can tell you they are very close, in fact I replaced my flat wraps with Semroc ones. They are so nice I did not even paint them!. The Semroc lander has updated material but builds an excellent, accurate lander. Some people have had trouble with stability, But I have not to date, and I have flown mine in 10-15 mph winds.

From the Mars Lander instruction manual available for download on the Semroc website:

"The Semroc Mars Lander is a faithful recreation of
the original. It uses laser-cut balsa fins and laser-cut
fiber parts instead of the original die-cut parts. The
fiber is also thicker for sturdier construction. High
gloss embossed wraps are provided for authentic
looks of the original. A slightly larger chute is provided
for longer life and a gentler recovery. A Kevlar
® cord is provided for better shock cord retention".

I have one still in the bag and it's well worth the $39 Semroc is asking for it.
