All those things are inseparable from propulsion.
How do you figure? One of the biggest safety issues for manned space travel is radiation. Do you plan on outrunning it?
At some point in the future, someone is going to fly to that comet, land, get out of their vessel and walk over to Philae and smile, give it a pat on the head, and then take it home; someone in the future is going to be lucky enough to experience that task and become a part of its history.
Off-topic, but why do they usually shoot black and white? Is it something to do with the file size?
I didn't get why this was important and the article didn't reveal it upon skimming. Since it seems to get people very enthusiastic I gave it a proper read. After 11 paragraphs, the actual news is revealed: > “This [...] means that we now have the missing ‘ground-truth’ information needed to put Philae’s three days of science into proper context, now that we know where that ground actually is!”
Scientifically speaking, a successful mission is one where you've gathered all the data for analysis and can work with it long after the mission is over. It's like, if SpaceX launches a rocket and it explodes - a real failure would be if they captured no telemetry and had no idea what happened vs knowing everything that happened and being able to replay the mission after the fact. Often times the data is far more imp…

If you have awesome propulsion then you can just bring a shitload of shielding mass.
Focusing on a point solution like "propulsion" is not even the right kind of question to answer "why not solve this problem with humans?".

We don't know just how low Philae can go, however, there is a good chance it's electronics won't break below the rated temperature.

Not sure how accurate it is, but an article found via cursory Googling[0] makes it seem like a true-color photo doesn't have as much scientific value as other spectrum recording photography - different filters over the monochrome camera can make it easier to see heat, minerals, radiation, etc. Goes on to mention producing a true-color photo is kind of a pain in the ass for these probes. 0. http://www.straightdope.com…
Cameras often have wavelength filters to allow recording only certain wave lengths, that can be switched. So taking a colour photo requires three different exposures. Depending on how long you can take a single picture and how much changes in between you may not really get a useful result. A Bayer filter like in common digital cameras these days would also reduce resolution and restrict you at the sensor level to col…
I watched this documentary called "To catch a comet" about the Rosette/Philae mission to comet Churyumov–Gerasimenko. The achievement of getting to the comet and landing Philae, like many other achievements in space, is really phenomenal. So many things could've gone wrong, but the fact that the worst was Philae bouncing and getting stuck in a dark place (and not being able to perform fully) is a huge success beset b…
Is there a map that shows its original landing site and the final resting place?
