Glad to know somebody else also recognising position:fixed problem. It's really a nightmare. Is it really difficult to understand for their product managers to see that blocking top 20% of user's mobile screen just to hang a navigation which serve no purpose whatsoever is not cool.

First - Great job finding this report. Thank you for that.

So had a look at the report.

There was one more problem actually. This machine, the MCO, had asymmetrical solar panels which would cause solar pressure ( force by sunlight ) to create a very mild spin ( angular momentum ). Now this angular momentum had to be desaturated time to time in order to keep this machine stable. Now, one module called SM_FORCES calculate this adjustment and feeds to AMD ( Angular Momentum Desaturation ). Now, this SM_FORCES & AMD uses different unit system, which was ignored by whoever wrote this connecting piece of program. Due to this error desaturation was not enough ( or more ) and it kept building over the period of 9 months.

Now, I notice that NASA has a separate team to navigate this machine to mars. There data showed this angular momentum adjustment event occurred 10-15 times more than expected. It was like a man walking with one leg shorter than another. It's a 9 months journey from mars to earth. They must have seen the first sign to inconsistency with in first few weeks only, just guessing though.

In this report, out of 8 possible contributing causes, at-least 3 are attributed to navigation team. I think success of such mission depends not only on meticulous planning but also on thinking on the feet ability of the team. ( Any Apollo 13 fans? :) )

Wait a second, it says they had to destroy mass climate orbiter because the development and underlying software used different metric system ?

It's bit hard to digest. ( Although just checked wikipedia, it also says so ) How can a high performance organisation like NASA could make such a simple yet fatal mistake ?

Wikipedia page of Mars Climate Orbiter says that NASA was informed about this discrepancy by two people, but the "concerns" were dismissed.

What am I getting wrong here ? These are not the "concerns" you simply dismiss in a space mission. Could there be another story to this ?

Just played with it a little bit. It's really cool. Do you have the same for android as well ? Or are you planning to launch anytime soon ?

Well, the best way to take out the garbage is to actually identify one - very first. Good that you have accepted this with complete humility.

Now, think over it, work hard, improve day by day.

I guess an "Idea" is much more than a website. If you are fully convinced with your idea, and have a in dpeth understanding what needed to be built, I don't think it can ever be replicated in exactly same form as you wished it to be. Just a thought. :)

Send them your portfolio and tell them why and how you can be very helpful to them. Easy ?
