Would it be reasonable to make the dataset from the previous competition (Mars Spectrometry: Detect Evidence for Past Habitability) available to participants in the current competition (Mars Spectrometry 2: Gas Chromatography)? Currently that data is no longer available for download and can’t be used to support model development in the 2nd competition.

Hi @bcoburn7. Thank you for this suggestion. We have released data from the first competition as supplemental data. It is now available on the [data download page](https://www.drivendata.org/competitions/97/nasa-mars-gcms/data/). Please see [this announcement](https://www.drivendata.org/competitions/97/nasa-mars-gcms/announcements/#supplemental-dataset-published) for more details.

@mchahhou the label classes from the first Mars Spectrometry competition are already included in the `supplemental_metadata.csv` file. Note that these label classes are distinct from and unrelated to the label classes in the Mars Spectrometry 2 competition.
