Just thought you all might like to see some 10X Mars Lander launch photos. Andy and I were successful in getting this beast off the ground. Scroll down to the bottom of this link for the photos...
Wow! That is truly amazing!

Very cool...
What did that thing end up weighing? How high did it go?

What an excellent launch photo. My video work didn't do it justice. I have some static shots if you're interested.
Thanks for the "show"!

Did Andy ever find someone with launch photos of the SV?
I didn't know you were allowed to post actual rocket content to rmr. :)
Great rocket and great project!
Jerry
Nice pics, Mike! Sure wish I could have stayed long enough for the launch.
Just awesome.
Good job, guys.
What was the lift-off weight?
Here is my proposed flight #2.

Mars Lander
1 N3000-STD 4 L1000-WS 2000# thrust (1.0 Ton) 1100 feet in 9 seconds. "It all happens in front of you."-TM/SM 2003Thanks, Jerry, I got the weight from the link you provided.
A quick question on your program?
The 132 inch diameter caught my eye. Is that the diameter of the landing legs? It just seems this would imply a LOT of cross-sectional area in a typical drag equation.
And don't take this wrong, I'm just curious; what Basic is your program written in and what is it running on? Years ago, I did some development work in Visual Basic (as specified by contract) on a GUI front-end for an IBM mainframe database application. I actually liked the integration of Microsoft's Access Database into the Visual Basic system (this is high praise from an acknowledged Microsoft hater) and the project was relatively easy to implement because of that. Of all things Microsoft, Visual Basic is about the only thing I've ever cared for. Well, okay, and Flight Simulator.
Body diameter. The legs are "fins".
That was run on Chipmunk BASIC on a Mac. It also runs on some DOS BASIC's :)
Wanna switch it over to something modern?
I would support that 5000%.
I'm not sure any translation I could make would move it into the "modern" era. ;)
I have no Windows languages or IDE's any more and I despise Java (Hack, spit. ) on "philosophical" grounds, no offense to Sun. Nor do I have any experience with graphical interfaces in GNU/Linux.
You would be much better off (in the sense of maintainability and expanding the user base) with someone who could put it on a Mac or PC with a modern OOP language and GUI running under a popular window manager (Windows, GNOME, KDE, whatever the Mac uses, etc).
But, if a command line GNU/Linux version in Perl, Python, or C would help, I'd actually be happy to translate it over.
I would BUY someone a Mac (BSD Unix with a fancy GUI OPTION) if they would port it to Codewarrior or something which is cross-platform.
Jerry
Had to look up Codewarrior; didn't know it was an IDE.
Someone familiar with C/C++ or Java is apt to jump on your offer. In fact, Jerry, a good IDE could make the translation of your Basic program to C, at least, fairly easy and C is about as portable as you can get. There are freeware/commercial programs which will convert typical Basic program files to ANSI, or other dialect, C source files. Buy YOURSELF a new Mac and go for it.
I would assume Codewarrior with a C cross-compiler package would import that C source file (which WILL have some errors) and tell you just about anything you needed to know to fix it; C analyzers, preprocessors, and debuggers have been around a LONG time and are very good at their jobs. The cross-compiler allows you to generate code for systems other than the one you are programming on, ie, produce a Windows program on a Mac.
A good IDE, or C package, can also provide a lot of help in adding the GUI I/O code. You could be cross-platform, if not ultra-modern, all on your own, AND have a nice new Mac programming station. :)
Just a thought. It will take a little research, but if you can write a useful Basic program, a C conversion shouldn't be too hard.
Lift off weight was 192lbs (ya should've seen me doing the CG with this thing - a story for another post). Anyway - had 25lbs of sand in the nose for balast. 4 outboards were started with a pull pin, the ejection was done with redundant timers set for 10.5 seconds - which actually turned out to be a little too long - should've used a MAD :)
We forgot to put an altimeter in it :( but sims put it at about 900 feet - low and slow.
- Mike Stoop
Well, it was our pleasure! Still can't believe we flew this beast.
Yes I think Andy did end up finding a liftoff of the SV.
When are ya coming out to CA again?
- Mike Stoop
Yea, the weight on that link was what we were trying to achieve :) Actually, our original target was 130 lbs - guess we missed that one too. We were a little too optimistic about the foam/glass construction technique.
So Jerry, did you think we'd ever get it off the ground when you saw it at Narcon? :)
-Mike Stoop
in message news:...
Absolutely. As I told you then, I expected it to work, to go really low, and that on landing it would break and that I strongly suggested sticking a thick dowel out the back to dampen the landing. Advise you did not take, and it did indeed break on landing, despite a perfect landing on a HUGE parachute.
I hope you can be there for flight #2!
Jerry
I would easily call it one of the top 5 best rocket flights of all time.
what's your list of top 5 flights?
This request is faaaaaarrrr too on-topic for rmr.
Lander
Kline Monocopter H5 (AT for USR of course)
Rogers 25k flight I was booted for (it was a great flight using a Powertech motor USR exclusive of course (the partnership between Kline, Rogers, Irvine, Kosdon, and others)).
Snitch C6-3 (okay 10 flights) at Four Corners USA (AZ, UT, NM, CO) with American Indian local residents present in true awe.
Tall Tail 10 (2xBT-70 + 2xBT-60 + 2xBT-55 + BNC-55 Goblin + 3" root 3:1 eliptical balsa fins 2" from rear + 24mm motor) mere D12-3!!! In front of stadium FULL of football fans. Standing O.
Any rocket with any K250 from either U.S. Rockets or AeroTech (Aero Technology Company).
Maxi-Orbital Transport at LDRS-1.
First rocket at LDRS-1. Hi-Test 2420 by USR using ACE parts of course!
Just Mere Jerry
reality check:
"Aerotech should change it's ads from 'the future of HPR is solidifying...' to 'the future of HPR is vaporizing...' "
- Bob Kaplow
"However as Aerotech has shown us time and time again, compliance is voluntary. They do not volunteer."
- Jerry Irvine
"But, your excessive delay problem really has one cause: the company that makes the motor. I have sworn off all Aerotech motors until they get the delay problem fixed. They have been the cause of the death of many rockets lately, both with their reloadable and single-use motors. This is a hard thing to do, since Aerotech has virtually a monopoly on HP motors, but I am going to work with Vulcan and Kosdon motors until Aerotech fixes their crap."
