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 two teams in the 2023 The American Rocketry Challenge (TARC). The main web site is The challenge is described in the 2023 Rules. This is a year-round activity. We recruited new members in the fall of 2022 and started to design and build our competition rockets. During the winter and spring of 2023 we tested our rockets.

We must complete three qualification flights for each team by April 3, 2023 to be invited to the national fly-off in May 2023. TARC adds the scores of the two best qualification launches. The cutoff for 2022 was 37.06. The finals are for the top 100 teams from registered teams across the US.


In the fall 2022 we started with five members from the previous year. We recruited five new members and created two 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 in 2023. Members must participate in designing, building, and launching to remain on a team.

We meet during normal Exploring Program general meetings for work sessions. Test launches are usually on Saturdays, Sundays, and other days when school is out. Each team will build several rockets, including test rockets and backups for their best models. We document our activities and results on these web pages.

Other Rocketry Programs

Due to our TARC ranking in 2021 and 2022, the Post was invited to submit a proposal to participate in the NASA sponsored Student Launch Initiative in September, 2022. Our proposal was not accepted, but we received helpful comments to consider in future proposals.

We then decide to enter a team in the Rockets for Schools program. We built a rocket from a kit provided by the program, and designed and built a payload experiment. We flew it in Sheboygan, Wisconsin off the shore of lake Michigan on the morning of May 13, 2023. (More)

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 The Plains and Walkersville.

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 Pike Park and Meadows 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.
