MARS landing
category: offtopic [glöplog]
Dudes! 12 hours till Curiosity touch down Mars. Anyone can grad this epic http://pouet.net/prod.php?which=4662 in order to celebrate?!
for real?
sTReam plz?
http://eyes.nasa.gov This is pretty handy too, even though we won't see the landing actually happen, we CAN get to see a semi-realtime animation of the landing.
really awesome what the nasa is offering and will mosdef offer concerning good HD visuals. tho what bugs me a lil what's written in the blog there. aboutthe transmission and the delay of the radio waves. i thought about that when they actually landed. how they get images so fast. there's quite some way from mars. and isn't radio usually a lil slow. thought they did it with a laser guided transmission from the orbiters as light travels faster. or i might wanna check my science knowledge again. :D
Yes, please check again. Both light and radio waves are electromagnetic waves and travel at the speed of light (or less, depending on the medium they travel through).
The commands for producing the first images were not sent by the ground station, they were hard-coded into the landing program. Hence, the only delay is the 14 minute transmission delay from Mars to the Earth, and you don't notice this, because everything NASA received was delayed by 14 minutes.
fart.

so basically you're saying that there's no live on mars! [sorry, the scene awards standup made me do it!]
rofl
lol thx trc_wm. i know that this was all coded and the initial delay of the transmission. after checking myself i guess i have mistaken the frequency with the actual speed of the emwaves again. *facepalms* so...

Today's image—Curiosity's first color snap—was taken by the Mars Hand Lens Imager (MAHLI), which, though clearly capable of photographing the horizon, is really designed to take close up pictures of martian rocks and soil. MAHLI is part of a Swiss-army-ish gadget arm that has five more instruments.
Not shown in the image is the Height And Velocity Observation Computer.
i has leading on mars landing: SUKKZ!
gasman: is that like... actual size?
Not far off actually, from the bottom of the wheels to the top of the mast is around 2m.
and i am really small!
2x 150 Mhz cpu's on the rover iirc..
