why is it that invariably some moron feels the need to bring something like this up ?



In Response to Free_electron,,,

It was meant as slight humor.

But from your response I'd rather be known as a moron than a clearly unpleasant person like yourself.

So what you were also saying is; your memory parity chip corrected the errors and reported what was happening to the system. Then along came the Monkey and you changed the module.

 :)

ps - Morons can do basic arithmetic; otherwise i couldn't have posted this response   ::) which puts us on a level field  Monkey :P

I read somewhere of a proposal for a solar system wide radio observatory to look into deep space. That would be some undertaking indeed but very interesting results would follow.Could even bee used to look for longer wavelengths than are possible at present.

We should start with an observatory on the moon.  It's so close.  Hubble has done a tremendous job by being above Earth's atmosphere.  Imagine being able to carve an observatory out of the lunar surface.

Are they planning on crashing the decent vehicle after landing the rover? I'd like to see them land it and then take it for a burn until the fuel runs out (5 seconds of fuel).

Remember when they landed that satellite on the asteroid or comet (I forget which)? That was awesome.

Just saw this: http://www.marsdaily.com/reports/Australia_is_all_ears_for_Mars_landing_999.html

The Canberra Deep Space Communication Complex is the main tracking station for the landing.

I think this one is running RTEMS, at least in parts, which is a realtime executive that was developed for military systems initially and is now public domain. Very robust and ported to quite a few systems now.
RTEMS.org for more details.

26 minutes to landing.  Here is the countdown clock:

Communication from Curiosity to Oddessy is strong. First thumbnail images just coming through now.

First 256x256 pixel image has just come through showing the rover wheel on Mars. The camera still has its dustcovers on the lense. Oddessy is just about to go out of range.

Here are the two 256x256 pixel photos. You can see the dust on the lens dust cover:



140Kg from 400kG of fuel left after touchdown.

Nice that it worked  :) , I would like to see the sensor data about what really happened.
I wish they stopped calling that picture "High Res"  ::)

Freak'n awesome!

But I'm pissed!
I was one of few people who didn't see it "live", and actually got a spoiler that it had landed, ruining the entire thing.
I went to the Sydney Observatory to see it as they advertised a live feed and figured it would be cool to hand out with the pro crowd watching this.
But it was a debacle.
Was supposed to happen at 3:30pm Syd time of course, and they announced they would start the live feed at 3pm. Ok, fair enough. Then we just watched videos until about 3:25pm when they decided to turn the live feed on. Great, at least I'll get to watch it...
No Wifi, so I wasn't able to see anything much on my phone apart from Twitter.
Then things just seemed a bit strange, I heard one announcer on the feed say 22min until entry and figured the timeline got screwed by some issue or something.
Then decided to check twitter to see what's happening and I see the NASA tweet that it had landed! and twitter melted down.
So I and a guy next to me who was doing the same thing looked at each other whispering WTF just happened?
And then we realised the "live" feed we were watching was massively delayed, by at least 20min it turns out, so we had to sit there deflated and watch he "live" feed knowing the ending. I have no idea how it was delayed or where they were getting their feed from.
Experience totally ruined.
Then we got a tap on the shoulder to keep our mouth shut, and they admitted they knew it was already down.

I should have stay home.
Thumbs down to the Sydney Observatory, what a bunch of dickheads.

Dave.

Just went on YouTube NASATelevision and some news company has blocked a video that NASA uploaded for copyright reasons.
Mean spirited b******s. I'll just have to watch the BBC later.
