Happy New Year to all! And Ron, thanks for your tireless efforts and contributions too! Looking forward to great things in 2008, in this project and others. ...
Now that I'm back from the holidays and my notes, computer, and me are all in the same location, I thought I'd summarize my discussion with one of the Mars...
Happy New Year to all. I have completed testing the new aerocapture code in my simulator using the published MSP-01 data (the best I can find). The results are...
I'm not comfortable with it because I doubt the validity of the MSP-01 data. I think that probably the best way to test it is to use it in a landing mode and...
In light of this, I favor slightly more strongly (i.e.: the difference between 99.9% and 99.95%) the use of seed hydrogen for the first mission (or perhaps...
This is simply quibbling, IMHO. The Mars 71 aerosehll was good enough to protect the spacecraft through entry. It was something that happened on touch down...

The minTES of the MERs have shown that the Burns Formation at Meridiani Planum contains up to 20% Mg sulphates by mass, there are patches of soil at Gusev with...

... Terry: I beg to differ. After reading reports for Spirit's landing, it is pretty likely she would have been lost without the DIMES and TIRS. Spirit's ...
... Other than what you already said about their atmospheric model? Er...nothing. The atmospheric model being that out of date on its own is enough to make me...
Hehehe...I'm happy. If Mars Challenger were flown as part of an ACMD or MarsDrive program, it would be fairly easy to modify a Christa class rover to measure...
Thanks Ron Unfortunately my workload is very heavy during the next few weeks. I will be looking at this towards the end of January. Regards David Willson From:...

SOP for analyses using MER instruments (miniTES, Mossbauer, and APX) is to take pre and post brush, and then post RAT readings, to get an idea of the ...
Christa's payload is called ASQ, and isn't beyond concept (Athena, the payload of the Exploration Rovers) was further along when Pathfinder hit Mars than ASQ...
Hi, all, I’m back from a week-end of overindulgence, celebration, and WAAAAY too much Bourbon Street (headache: yes; regrets: no way!). I have extended the...
Impressive! The only glitch I can see is that you state the graph colors as black and red, but I have them as navy and magenta, as though the printer were out...
It would be great if I could get a copy as I only see this error message on the page Attachment(not stored) Aeroentry Simulation.pdf Type: application/pdf ...
Hi to all for 2008 and thank you for an amazing year last year on this design. We covered many questions in what has always been a controversial subject as we...
Well, we all knew a 28mT lander with a 7.5 meter heatshield would not slow down to anywhere near Mach 1. Turns out my simulator says my lander augers in at 658...
i remember seeing something on the science channel's "mars rising" in the "six minutes of terror" episode it talks about an "inflatable heatshield". i'll get...

Frank, First of all, let me say that I think what you (and all of us) have done so far is fantastic! I'm looking forward to seeing further progress in this new...
I expect that to light the engines under these circumstances, your exit pressure would need to exceed the local static pressure (not much) plus the dynamic...
Nice work Ron. What happens when you run the simulation using orbital rather than direct entry velocities? _____ From: marsdrivemission@yahoogroups.com ...
Jon, That is from orbit. Entry velocity is 3645 m/s. Entry angle is - 3.9 degrees. About as gentle as you can get. Ron Ronald M. Cordes 3 Jeffrey Circle ...
