In this case, the "corrections on the fly" refer to all of the real-time responses that the software makes without ground involvement. In the case of a solar limb sensor detecting the sun, the probe will abandon its data collectio

It seems like you want to discredit NASA now ("shouldn't melt") vs some imagined possibility("won't melt" but it does). With the amount of design, analysis, testing, and independent review and verification of t

(former software engineer on PSP here) It's a certainty that it will melt eventually, but that's not a satisfying answer to the question "why won't it melt?" The satisfying answer is "for the time period when i

It's been a traditional at JPL (and other NASA centers) to wear matching polos for quite some time now, at least years, before the Rosetta landing. Not saying that NASA is better than ESA as far as women or PR goes, but this wasn'

Is that an actual quote within your quotation marks? Or are you creating your own straw man and attributing it to them?

It appears to be a photo post (i.e. images uploaded to FB natively) as opposed to a link post, where FB chooses a thumbnail for you (or not, if it's a YouTube link). I've been seeing posts like this when friends upload image album

As someone tech-savvy and having used WireShark, even, I'm curious to know from my sibling commenters, what are you thinking? Of course you start by buying hardware or modifying a router. Parent comment is specifically asking for &quot

Source on that? Even the Tajectory Correction Maneuvers (TCMs) are planned in advance, and it's just the details of the TCM that are finalized in the lead-up to those events. As far as the final approach goes, the core sequence started

It's not like these copies replace the higher-res ones. Not a project scientist, but I'd rather as many people as possible see some image than only a few see only any at all.

It will take months to transfer the full data sets back. The data are formatted in ITF packets, inside CCSDS packets, inside CCSDS transfer frames. [0] http://public.ccsds.org/publications/BlueBooks.aspx [1] http:&#x2

And we're still not flying memory sticks (but we are flying more memory than ever before). Fun fact: New Horizons has no file system on its recorder, but current missions at APL now do. http://flightsoftware.jhuapl.edu/

The main command and data handling processor runs code written in C, as does the guidance and control computer. However, the G&C algorithms were 'written' in Simulink, and autocoded to C. I believe the instruments also use C,

He didn't have a hunch, he just knew that the standard comprehensive test was skipped, which is why the standard test procedure only detected a problem, and he had to end early and go off book in order to reveal the doppler problem.

I don't see anything there (under favorites or subscriptions), but I didn't expect to, either, since I was never asked to log in. It would be very nice, though, to be able to add videos from my subscriptions to my watch later list, and then

I try to do the same thing in lectures. Unless I'm late or the lecturer is a particularly fast talker, I can usually process the information to the point where I'm writing my current understanding in my own words. Much better for me than ta

I think an important distinction is that he was not completely idle, as in playing cards, but solving a problem, albeit one with no clear relevance to anything.

Limited budget is certainly a big reason, and another is the lack of a pipeline. When Apple releases a new iPhone every other year, it's not like they started development on the next model only after the current one is released. Development

Very cool concept and enjoyable game, but it caused the Iceweasel 'plugin-container' on my laptop to use over 200% CPU, which I'm guessing is related to the circuit breaker flipping (twice). Running Crunchbang 11 on a Dell Latitude E6410...

Go to space companies and apply for positions with "avionics" in the title. It'll be a mix of people from software and hardware backgrounds, but everyone deals with hardware on a low level.
