NASA Releases Report on Mars Exploration Program 119
latcarf writes, "The lead article on NASA today is about the report on the Mars exploration program - a program that hasn't gotten much exploring done recently. It concludes that the loss of the Mars Polar Lander is most likely due to premature engine shutdown and that the cure to such problems is less "faster and cheaper" and more time spent testing systems at greater cost. The article about this report on CNN includes an interview with Tom Young, formerly with NASA, who relates problems with tests on the Polar Lander."

There is a lot of other areas where NASA could go a long way to reducing costs without compromising quality control. Deep Space I with it's ion drive is a good example. The use of ion drives/light sails/tethers/etc are all technologies that have long term applications in space and NASA can make a major contribution in these areas.
As for getting to Mars, the number one problem is still the basic launch system. Chemical rockets are literally WWII technology. In terms of human crewed flight, I don't think that we are really going to get anywhere much without nuclear fusion.
In the 1950's, the Lawrence factor for magnetic confinement reactors was at 1/100,000. Today it's down to 1/10. That's an order of magnitude per decade. Within the next 10-20 years, we will probably see self-sustaining fusion and from there it will probably be another 20-30 years before it could be used as a spacecraft drive.
If you can assume fusion, then a Mars mission is not only easy but cheap in comparisson to chemical powered rockets. So it can be argued that the best way to promote space is to put the boot up congress to get serious about fusion.
It would also have the side effect of also eliminating all of these pesky arguments over green house gas warming as well. ;)

At least, that used to be the case.
Now there is competition with the Applied Physics Laboratory (Johns Hopkins U). They have sent several NASA probes out, mostly with success (the most recent being EROS). The researchers there truly embody the faster-cheaper-better mindset.
JPL needs a swift kick in the ass for the shoddy work that they have done. Lets hope that places like the APL provide that.

Goes against the whole grain of modern programming (Score:1)
The quest for systems which are "faster and cheaper" is what our modern equivilent of "computer science" amounts to. Newer, high-prodcutivity languages such as Java and Visual Basic allow programmers to do just that: develop applications faster and with less bugs, thus reducing both the need for testing, as well as costs.
While I don't know which language they use, I can only assume that it is a legacy language such as C++. Although it costs money to translate this into a safer language like VB, overall it reduces costs, especially over the long run. I urge them to consider the switch to a modern, complete, object-oriented language and toolkit. It'll be easier on me as a taxpayer, and you as a programmer. I know at my place of employment, we had to re-train/hire/fire developers in order to rid ourselves of legacy code written in C++, but overall, the jump in productivity has been great. We've even been looking into "freeware" operating systems such as Linux, FREEBSD, and Python as alternatives to Windows NT 4.0.

BTW, there was a report on UPI last week that said that NASA apparently found out that the probe would have blown up long before landing, because the engine was too cold to work right... check the usenet group sci.space.policy for info on this. Basically, it seems a Lockheed manager had some tests with the engines rigged (i.e. heating of the catalyst bed) to get the engine to pass the test. NASA found out about this shortly before the probe reached Mars, said they found a fix (which probably wouldn't have worked), and are now ignoring that cause in favor of this last one. Hmmph.

The real effect of Open Source is not so much in thousands of people wiring thousands of lines of code, it is in thousands of eyes looking at the code, and one of them seeing a problem. So, why not publish all the design documents and all the code as you go along? Doing so would not cost much, and I am sure many readers here would like to have a look. It would require perhaps one full-time person to moderate a mailing list or web site with discussion, and to select the most relevant-looking stuff to be forwarded to whom it may concern. Just knowing it was going to be published might help the busy programmers and engineers to keep their motivation up.
Plus, it might well give NASA good publicity, no matter how the project went. If bugs were found and fixed in time, fine. And even if the project failed, at least there would be lots of people around who have seen the complexity of it, and might have some understanding for it, and voice it in various places.
In short, I think NASA may gain a lot by publishing everything, at a pretty low cost. Why not give it a try?

If the coders get to churn out a hundred lines of code a week, averaged over the entire project, they're lucky. If they're pressed for time, they aren't going to cut corners in coding, but testing and integration.
VB is only a higher productivity language for certain classes of problems (simple forms based interfaces with database access and a couple of visual ActiveXs bolted on for eye candy). It works really well in this space, because of the IDE, not the language itself which is execrable and error prone. Essentially you can integrate all of your application components (database, ActiveXs, forms) within the IDE and test them iteratively.
I admire the Java language greatly, but really it is not that different from C++; mostly it is noticeable (as a language) by what it leaves out -- among other things pesky and error prone pointer arithmetic. However, I doubt NASA's problems are related to stray pointers -- they probably use ADA. Java also has an innovative runtime system with nice security features.
I think it is interesting that a lot of the value of these "languages" comes from the infrastructure that exists around them -- the design time IDE in one case and the runtime system in the other. What it suggests is that NASA needs to, over the long run, develop a robust and reusable space exploration rapid prototyping system. It would include standard hardware components, testing apparatus, highly tested reusable software objects and a standard operating system. Real time Linux? It would make a lot of sense for vendors to deliver source code to NASA under a license that would allow subsequent vendors to reuse it.
I don't think coding productivity would make any changes, but it would probably make integrating the entire system faster and easier.

The engineers who did the basic research in those days are long retired, but in past decades they had a long time to transmit what they knew to the younger generation of engineers. Sorry if this offends any of the younger crowd, but freshly minted college graduates are not really fully trained. They have all the basics, but real-world experience is absolutely essential. When there were a large number of experienced older engineers in the workforce there was a kind of informal apprenticeship system in place whereby the new generation received this training. But because this was never codified or formalized, the pointy-haired bosses of the industry never took serious note of it. Under the pressures of "better, faster, cheaper" the began to look for any way they could to cut costs - their own salaries and perks being sacrosanct, of course. Their jaundiced eyes soon lit on the senior engineering staff. They were all older, and with accumulated seniority much more expensive. Why, a PHB could hire three new grads for the cost of just one of these old guys! So out the door they went, either laid off or forced into early retirement, and they took their knowledge with them.
In most cases the knowledge lost wasn't the kind of information that any PHB could apply simple-minded metrics to and put down on a balance sheet. They were all the little things - habits, ways of working, all the reflexive sanity checks that ensured that the numbers that came out at the end of their procedures conveyed the information they were intended to convey. They would check and doublecheck things like unit conversions and software loads just because that's how they worked. And by and large NASA projects worked too.

Nasa still likes to crash things ... (Score:2)
Remember way back when we were all five and we would crash things and make the big `splosion noises then go eat macaronni? Well I think nasa is just one noodle short of a 5 year old here.
Another thing. If you were an alien considering making contact with the so called superior organism would you take kindly to them crashing things into your planet or bringing remote control cars in your lawn? ... no of course not.
If nasa wants to keep good PR with mars they need to negotiate a landing zone and coordinate a way for the lander to enter into the martian atomosphere. This crashing business will just cause the martians to have ill feelings towards humans and we just can't have that.

One of the problems with NASA is it doesn't have a particular mandate. We don't have a race with the USSR anymore and NASA has lost focus. Mars, because of the cost involved, doesn't have the sexiness that putting a man on the moon did. I think NASA, and the US gov't need to devote more money to NASA. Hell, I think NASA needs to become more of a world organization. We need to get the whole world involved in this endeavour. I'd rather see money spent on NASA than the United Nations.

Bullshit. Don't accuse someone of knowingly delivering a defective component if you can't back it up with evidence.
Obviously the problem is that NASA and its contractors make mistakes. Well, we will just have to fire them all and replace them with magic robots who never make errors and will work unlimited hours for free.
I work for a NASA contractor and have seen the effects of faster and cheaper up close. It's like Stalin's purges, every month more people disappear, never to be seen again. I haven't seen a new hire in years. My boss is retiring this week and his position will disappear with him. Time to print out another org chart.

Pumping money into food for starving people will not alleviate the problems that made them starve in the first place. As the saying goes, if you give a man a fish he'll eat for a day. But if you teach him to fish, he'll eat for life. Which leads to education. This is certainly a good goal, but again the solution is not what one would expect. Throwing money at a problem has never created a solution, not in the entire history of our race. Throwing money at education will not create better schools or better teachers. Perhaps they need more money, but this is not all they need. They also need wild and crazy reforms. Being a recent graduate from an American high school, I can say that the US school system is breaking at the seams, and it's not because it doesn't have enough cash lying around.
Other countries may be different in this regard. Perhaps their systems are fairly decent, but just don't have sufficient money to run them. For the cost of one Mars Polar Lander each year, you could pay for roughly sixteen thousand teachers at ten thousand dollars a year. Not a lot in this country, but in the countries that need it most that salary is incredibly luxuriant.
I think that scientists understand that the best thing they can do is to further the human race. However, they also understand that the greatest scientific discoveries in history were made by people not expecting to make the greatest scientific discoveries in history.
What NASA is really saying (Score:3)
I think NASA is basically saying that they are going back to the way things used to be. It was more expensive, but it was also more cost effective. I think NASA is less concerned with public opinion now, and more with science. It's for the better. I hope it lasts.

NASA has the complete reports [nasa.gov] on the Mars Polar lander incident and on recommendations for the Mars exploration program in general. They also have a press release [nasa.gov] (though the server seems to be down).
The basic summary is that "better, faster, cheaper" can work, but some management and structural changes have to be made in order to ensure the success of the Mars program.

There was a full-scale test of the suspect software before flight, but some sensors were incorrectly wired, Young said. After the wiring was corrected, the test was not repeated.
Insert "D'oh!" here. (Or perhaps the sound of one hundred thousand people saying "whop.")
Seriously, has NASA's budget and time window really shrunk so far that they can't afford to utilize basic tenets of software testing and design? If so, Congress really needs to rethink the constand slicing and dicing of NASA's fundage. I've seen projects that were released without adequate testing (which I later had to support...grrrr....), but the consequences there were an increase in work time and client frustration, not the loss of over $100 million of spacecraft.

ISS and federal allocations (Score:4)
Now throw in the fact that the ISS has developed a huge political momentum, which means that its money is sacrosanct - ISS allocations actually increased last year - which meant that the chunk of money that was supposed to be skimmed from NASA's budget almost all came from the planetary and earth science budgets. Remember when there was going to be a rover on the Polar Lander? That's where it went. These projects were cut to the bone, leaving too few engineers working too much unpaid overtime to finish the lander.
So to the people out there complaining that NASA just wants to return to the "good old days" of multi-billion dollar missions, think again. The press release [nasa.gov] put out by NASA even says that they're going to continue with the "better, faster, cheaper" philosophy, but "properly applied" this time. Essentially, all they really want is the breathing room to hire a few extra engineers, to retain the most experienced workers (think "institutional experience"), and do tests over when need be.

I could go on and on. Why isn't Nasa seen as a tech company instead of just another gubbermint agency? Maybe if we privatized it and put it on the Nasdaq, it would get more respect from the press - and some better mission success rates.
Privatize Nasa? (Score:5)
The disadvantages to a private NASA are few but are very important. I would think that this private agency would be one motivated by profit and less by pursuit of knowledge. This would probably affect certain decisions made by project managers. While NASA does work under tight budget constraints, its goal in conducting exploration missions is the collection of data for public distribution. I can forsee a private company claiming ownership of, lets say...rock samples collected by a lander.
If NASA was privatized but still retained some government control, I think it would be better off. I think the government still should regulate who has rights to building massive rockets carrying tons of highly explosive materials. The government should also claim public ownership of any scientific discoveries made by these exploration missions. Heck, I'd hate to finally make it to the red planet someday just to see flags with the microsoft logo on them planted in the dust.
To say all government is evil and detrimental is silly
