The group goes on several all-day field trips to nearby scientific institutions.
From New Mexico Tech typical destinations include the Very Large Array (of radio telescopes) and Sunspot / Apache Point Observatory.
From Boulder the group may visit Lockheed Martin, Space Science Institute, and naturally, Fiske Planetarium where the Director, Dr. Doug Duncan, is SSP '68.
In a given year, there might be an extra, off-topic field trip focusing on, for example, geology or archeology.
Non-academic off-campus trips -- swimming or shopping, for example -- also happen regularly.
