About this site
There are many scientific tasks that require human perception and common sense,
but may not require a lot of scientific training. Identifying craters on Mars is
something almost anyone can do, and classifying them by age is only a little harder.
The original pilot study (2000-2001)
From November 2000 to September 2001, we ran an experiment that showed that
public volunteers (clickworkers), many working for a few minutes
here and there and others choosing work work longer,
can do some routine science analysis that would normally
be done by a scientist or graduate student working for months on end.
- The clickworkers pilot study produced some very impressive results in 2001.
Results: Mars age map produced directly from clickworker inputs
crater-marking inputs have been combined into a map of the ages of
different regions of Mars. It agrees fairly closely with what was
already known from traditional crater counting. The image above
compares the two versions. A higher-resolution one and more details are available.
- All the activities are still up and running, although they have largely served their purpose already.
can still do any of the other activities if you want to. We’re
unlikely to learn anything new from them, but you never know.
- Craters in the Viking Orbiter Mars Digital Image Mosaic have already been
marked 40 or 50 times over, more than enough to prove the point, but you can do more if you want to. Be sure to try the training session.
- If you like, you can try the old fresh/degraded/ghost classification system, but we have plenty of entries already.
- The honeycomb search
failed to turn up any new examples of honeycomb terrain, according to
Dr. Moore. Perhaps they really don’t exist. When given the one known
example they’ve already seen (but upside down), 69% of clickworkers
identified it as honeycomb. The most common false identifications are
layered deposits in the polar regions being mistaken for honeycomb.
- You can still try Mars Pathfinder magnet images just for fun.
