Hello, there, Ladies and Gentlemen of the Internet: My name is Jeff Cunningham, Director of Public Affairs and your point-of-contact with Earthrise, better known as Team Omega Envoy. I’ll be posting from time to time on our mission’s progress, as well as weighing in my thoughts and perspective on the importance of the X Prize competition, space in general, and how it all impacts the average Joe Blogreader (hint: it’s a good thing).
There’s a great deal to catch you all up on. First of all, publicity: Jason Dunn and I had the great honor and delight of speaking at the Space Vision 2008 Conference put on by Students for the Exploration and Development of Space (SEDS) at Texas A&M University. For those of you just tuning in, SEDS was founded some years ago by three close friends and classmates while students at MIT. Among them were Bob Richards, CEO of Odyssey Moon, one of our competitors, and Peter Diamandis himself, Founder and Chairman of the X Prize Foundation. I’m sure I speak for us both when I say SEDS has done a lot for me in my life and career (and given me more than a few stories for the grandkids), and we were glad to have a chance to give back.
It was also truly great to meet Will Pomerantz (himself another SEDS alumnus) in person to discuss the contest, and to spend a weekend with so many others who share our passion. Our presentation, along with the others who presented, was videotaped, but they (Texas) have yet to post it. They’re probably preoccupied with final exams around this time. If they’re unable to, I’ll get permission from them to post up my copy of the footage so you all can see how awkward we are on stage.
Next, a technical update. There has been next to nothing said here so far in terms of our progress in actually making the rover, which will no longer be the case from here on out. I’ll start by backing up and talking about our overarching strategy. This team started as a group of engineering students meeting in secret, and was founded on the basic principles of engineering: Solve the problem in the simplest, most inexpensive and efficient way possible. To that end, our design and mission architecture is nearly entirely based on the use of available, “off-the-shelf” hardware. In the years since the heroes of Apollo landed on the moon, the aerospace industry has matured to the point where there’s really no need to re-invent the wheel.
In fact, thanks to these advances in technology and market development, we decided that there is no reason why the Google Lunar X Prize can not be won for less than the prize money offered. Merely a year ago, such a notion seemed unattainable, but with the successful launch of SpaceX’s Falcon 1 rocket, we don’t sound so crazy when we assert that this is entirely within the realm of possibility. All that remains to us is to design a simple, cost-effective rover craft.
You may have seen our initial concept, our beloved shoebox-on-wheels. We’ve since re-examined our design, and will soon post a render of our most current iteration, which folds up more compactly into our payload fairing—and looks really darn cool. I swear, with the reflective exterior we added for thermal protection and the surface on front that takes on the appearance of a “grill”, it’s like how Wall*E would’ve looked if he’d been built by BMW.
It’s by no means finished (otherwise, this’d be a launch announcement); there’s a great deal of tweaking to be done to accommodate additional cameras and different computer packages we’re looking at. I myself hope to spend some time during our semester break looking at the possibility of swapping out some of the structural members in the body for composites. This would help reduce the weight and improve the rover’s thermal characteristics.
That’s all for now. In future posts, I’ll catch you up on how our team was formed, and the adventure we’ve been on ever since. I’m also truly blessed to work with an amazing group of dedicated and talented men and women on this project, and look forward to introducing you to them. Until then, do yourself a favor and steal a skyward glance tonight before you call it a day. Think of it as “Carpe Astra”.

Assuming...
If you can construct a rover that will be capable of completing the required challenges, and that you will rely upon a company such as SpaceX to provide you with the launch vehicle, transorbital injection vehicle, and a lander, how do you plan on being the first in line to launch? Being the first team to launch would probably carry the greatest of mission failure, but the sooner you launch, the better chance you have of winning the GLXP.
So how do you plan on convincing Elon Musk that you deserve to be launched first?
Response to Assuming...
@Mabus Sanchez, I appreciate your comments. First, lets get a few things straight: we will be building our lander, rover, and all structure to bring everything together, but yes, we will be purchasing our motors. Also, why do you say "Being the first to launch would probably carry the greatest of mission failure." Why? I am not sure I understand why you think this. Also, are you assuming here that every team will be planning on using a rocket from Space X, because this is not the case at all, in fact, we aren't even saying that we are locked in with Space X.
I'd like to hear your comments on this!
Sorry this was a short response, I am at the team summit in Mountain View, Ca. right now discussing the rules.

Answer to your questions....
I am really glad to see that people are reading our posts, let alone commenting on them, thanks guys!
I'm not going to say much more than Jeff has already said, but what I can reiterate is that we are not here to "reinvent the wheel." We do plan to make it more affordable, obviously, and less intricate. I do agree, the mission design is extremely important, and not an easy task. I can say that we have an excellent team working on this and we feel confident with what we are working with right now.
Stay tuned for our CGI animation of the mission which will give a pretty accurate depiction of what our mission plan is. We should start showing clips of this in the next few weeks.
Until then, Ad Astra...

The Four Essentials
Phil's right about that. But I am glad to see that you are in the minority that thinks even the contest itself can be won on a profitable basis. Launch vehicle, transorbital injection vehicle, lander, and communications to articulate it all. With those four, any Radio Shack toy will perform to some (albeit perhaps limited) extent on the moon.
Hi - it's good to see
Hi - it's good to see progress being made, and reported on! You mentioned Space-X, which is certainly one route to orbit, and the design of a rover. But it's surely not quite correct to say "All that remains to us is to design a simple, cost-effective rover craft". There's a big step between the launch vehicle and the operation of a rover on the Moon, and that's the cruise to the moon and the landing. I know you know that, we all do, and I think in some ways it's going to be the hardest part (at least for teams who buy a launch from an existing provider). Are you in a position to comment on that stage of the journey?

Hi, Phil! Sorry we took so long to get back to you. It's just as well, because, if I had answered you right away, I would have given you a different answer.
It is absolutely true that getting to the moon is not as simple as just doing a one-time burn from LEO and coasting all the way there. We thought we were pretty settled on the upper stage(s) we'd use for TLI and braking. After taking another look at the numbers and the product we'd chosen, however, we realized that we need either a different engine(s) that would allow us to make more course corrections en route, or go with a different trajectory that wouldn't require so many in the first place. It's a conundrum in and of itself, but one that a very competent friend of mine is working on.
