The summer visit to Caltech is 3-4 days long and is the only time during the year of work when all the participants on the team come together in person to work intensively on the data. Generally, each educator may bring up to two students to the summer visit that are paid for by NITARP, and they may raise funds to bring two more. The teams work at Caltech; the summer visit typically includes a half-day tour of JPL.
The SED team came to visit in August 2010; the team's core educators attended.
