We invite members of our other projects to join us in building and launch activities. We have fun running around the launch fields and sometimes they have an opportunity to test quadcopters.

Explorer Post 1010 registered three teams in the 2020 The American Rocketry Challenge (TARC). The main web site is The challenge is described in the 2020 Rules. This is a year-round activity. We started with experiments focused on the challenge in the summer and the fall. We recruited new members in the fall and started to design and build our competition rockets. During the winter and into the spring we will test our rockets at least once a month.

We must complete three qualification flights for each team by April 6, 2020. To to be invited to the national fly-off on May 18, TARC adds the scores of the two best qualification launches. The cutoff for last year was 34.48. The finals are the top 101 teams from 925 registered teams across the US.


This year we started with seven members from last year. We recruited five new members in the fall and now have three teams. To be on a team you must be a dues paying member of Post 1010 and have your parents sign the TARC permission form. Members may switch teams until the first qualification flight. Members must participate in designing, building, and launching to remain on a team.

We meet during normal Exploring Program general meetings for work sessions and on Saturdays, Sundays, and holidays for launches. Each team will build several rockets, including test rockets and backups for their best models. We will document our activities and results on these web pages.

Launch Notes

Wind speed is a big problem for our rockets, so before we launch we check (Manassas, Frederick). The Weather Channel is another source for weather at the Virginia Site and Maryland Site.

When we launch in strong wind, our biggest concern is the loss of our rocket in the trees. We have plotted out launch limit maps for Maryland and Virginia launch sites.

We always need parents to drive to the launch sites. Participants should bring money for lunch or bring food when we are out all day. Wear appropriate clothing. Schedules can change at the last minute due to weather, so keep watching this web site, your email, and call if unsure.
