A science attaché is someone who works for their country's government in a foreign country to help with science-related things. It's kind of like having a special helper or ambassador for science stuff! They might help scientists from their country connect with other scientists in the foreign country and work on joint research projects. They might also keep their own government updated on all the cool science things happening in the foreign country. Basically, they're there to make sure that scientists and science get the support they need between two different countries.
