"Old" news and it has been already addressed on this thread. Just read back it (or search for "a-side").

QUOTE (Tesheiner @ Apr 3 2013, 01:40 AM)  "Old" news and it has been already addressed on this thread. In fairness, there has been little detailed information about the problem from JPL, and most of the discussion here was, ah, speculative.  I wouldn't say that Robert's questions were actually answered. -------------------- Disclaimer: This post is based on public information only. Any opinions are my own.

I don't know the answers, either. -------------------- Disclaimer: This post is based on public information only. Any opinions are my own.

QUOTE (fredk @ Mar 30 2013, 07:07 PM) It's not clear to me how much the LEDs would help during the day, but at night that should work. A bit out of context, but talking about night-time LED made me wonder when the first artificially light on Mars was switched on? I don't think it is MSL as the Phoenix lander had some red, green, and blue LEDs to illuminate the inside of the scoop. Does anybody know if another lander/rover had some LEDs and when it was switched on for the first time? (I couldn't find any relevant information in this forum or otherwise. I might just not know where to look for it...) |

The Viking landers each had multiple light sources, though none were intended to illuminate the Martian surface or exterior spacecraft components. Each camera had pinlights in their fixed-posts and another within their optical assemblies (near the lens cluster) for testing and calibration. The Biology instrument had a xenon lamp to simulate sunlight during a growth experiment.

...and the MOLA laser was an artificial light illuminating the surface, albeit not quite at visible wavelengths.

Phoenix's Lidar Beam produced the first laser light show on Mars.

So the April hiatus has officially begun. I guess the team at JPL will have a whole month off. Wow. How will they cope?
 I'm just joking, hope everyone can catch up with their families and relaxed because it has been a great mission so far! But when May comes around I hope everyone will be ready to be roven again.

That's fascinating. I just think that having an artificial light source on Mars has quite a symbolic character considering how important light always has been for us and how much we sometimes celebrate the illumination of buildings, bridges, places, trees etc. |

Since Curiosity is not dependent on Solar panels and has artificial lighting, I'm looking forward to seeing it explore a cave (if it finds one).

That would be fun for sure, but communication might be a bit of a problem...

Nice new presentation here from the Planetary Science Subcommittee meeting just finished.
