A SPICE beginner's training class was held in Arcadia California on June 4 - 6, 2019.
Dates for the next domestic class have not been set, but it is not likely to occur
before the late Fall of 2020.
The European Space Agency anticipates holding a beginner's class at its ESAC facility
near Madrid, Spain, in the Summer of 2020. Look at the Training link found on
this page for any news: https://www.cosmos.esa.int/web/spice
It may be possible to hold classes elsewhere, with support from the host and with NASA approval.
If you are interested in SPICE training classes you might talk to your space agency's management
about hosting a local training class.
Self training is another option you might consider. This option
makes use of the same tutorials and lessons used in the live training classes.
No Internet-based Training
Because of the importance of the hands-on programming lessons that are part of the
SPICE training, NAIF does not offer any kind of webinar or filmed (e.g. YouTube) training.
