...and they need our help to spread the word...
What problem would be so important that NASA scientists and engineers would be willing to work independent, unpaid, on their own time, to find an alternate solution?
For the last two years those familiar with and interested in space, science, and technology (like me) have heard and have been excited about the development of a new rocket, one planned to not only replace the Space Shuttle, but also to eventually return to the moon. This project is called "Ares", with the two designations, "Ares I", and "Ares V", being the names of the two rockets being built. Upon hearing about it, I thought the plan was done, the course was set, and NASA and the scientific community's mind was made up. It seemed like a good idea to all-- or so I thought.
A couple weeks ago I learned about something that has radically changed my view of the Ares project -- it is that there is a problem big enough with the Ares project that at least 57 NASA and some other independent scientists and engineers are willing, unpaid and during their free time, to develop an alternate proposal to that of Ares, called Jupiter.
Wow -- that caught my attention. However, the first article I read didn't give a whole lot of details, and primarily gave NASA's point of view on the issue. But since learning more, I'm beginning to understand where these scientists are coming from.
The issue is political
I have noticed that many articles about the Jupiter project miss the whole reason these scientists are doing what they're doing. Many of the articles emphasize that the proposed Jupiter design claims to be "safer" and "cheaper", which is true. But if all these scientists had was a safer and cheaper design, would that be sufficient cause to risk losing their job over? Nobody is doubting that NASA is capable of building a safe and operational rocket, that can do everything they have outlined it to do. The real issue is political. These 57 scientists strongly believe that if NASA were to go the direction they are going now, and then lose political backing half-way through, then America would end up losing much of our space program's infrastructure that is in place today. We would be set back to the days prior to the Space Shuttle!
The original plan of the Ares project was to reuse tried-and-true technologies in a new form so to be a new and more capable rocket then we've had before. However, it hasn't happened quite like that. The Ares design today is much different than the Space Shuttle, and uses many technologies which are new or still in development. It's different enough that many aspects of the current shuttle, such as the shuttle launch-pads, manufacturing processes, etc., in addition to the skills and knowledge of experienced engineers on these topics, will all be replaced. If at the point of transition political backing was lost, that is where so much would be lost. Also realizing that these changes are causing the completion date of Ares to be pushed all the way to 2015, and realizing that Ares requires the development of two rockets, not just one, the chance of losing political backing is too big for comfort.
Instead, these rouge scientists have come up with an alternate plan. They propose to do what we were going to do in the first place -- stick with what we have: the space shuttle parts that already have established designs and fabrication plants and experienced engineers to support them. Use those parts and build us a rocket that does the exact same thing as Ares! And we'll build ONE rocket which can fulfill the purpose that the two Ares rockets fill, cutting development costs even further. These scientists have a preliminary design, and have named their concept "Jupiter". Yes, not only is it a bit safer, but the important thing is that it'll be developed faster and with smaller development cost, thus having a far greater chance of being completed within the timeframe of political support! In addition, it offers to maintain the vast majority of the current infrastructure of engineers, manufacturing facilities, launch pads, and other important parts of the space program. It also offers to do with one general rocket design what the Ares project intends to do with two. All in all it has a far greater chance of overcoming political hurtles.
**
More and more people need to know about this project, because for the good of our country's space program, this proposal deserves a full-fledged review by NASA. So far it has only received an unofficial review, and in some cases NASA is simply ignoring it. Maybe NASA knows what they're doing, and for reasons unknown to the outside public there are better reasons to stay with Ares. But on the other hand, maybe NASA just doesn't want to lose face when their much-publicized Ares project is abandoned! Either way, the answer will only become apparent after a full official review. After so much work, unpaid, and putting their own jobs on the line, these scientists deserve it.
