0848 Team Members under the parent nonprofit Together We Shine hosted our 2nd year of free workshops in partnership with the San Diego Public Library. A Intro and new Intermediate Rocketry coursewere offered. More details at: https://www.togetherweshine.org/events

With our qualification scores and marketing video finished, 0848 Horizons is now on post season activities. These include:

• Outreach for recruiting new members for the team as 6/9 are seniors.

• At the parent nonprofit, Together We Shine, host more free Rocketry and STEM workshops to spread the hobby around the community.

• Designing and testing preseason/hobby technologies such as landing legs, advanced airbrakes, better algorithms, etc.

Unfortunately, it seems the best of Murphy's law has grapped 0848 Horizons. During one of our qualifications, we had a loss of connection to Booster 5 after a record-breaking 7th flight using the same booster. Metal fatigue caused the swivel to snap. The other two qualifications end up with scores of 39 and 56 respectively, far from our 10 expected from the last launch, due to environmental conditions. However, since this is our first year in TARC, we hope to learn from this and be successful for future years!

After a rigorous 7 launch testing campaign Zenith 3 and Zenith 4 across 40 days, Horizons is ready to attempt a qualification flight on 3/19/2022 at the NAR Club Vocational SteamWORKS Rocketry (VSWR). Target parameters have been booted up into the flight computer and after a small parachute tuning, we will be ready to attempt our Q. Flights. ZN3B (upgraded subsystems) will serve as the main rocket with ZN4B acting as a substitute. o7

0848 Horizons was graciously interviewerd by Scripps Ranch News to spread the word of our team within our local area. The news story can be read here:

In the last practice launches of the Zenith Program at Vocational SteamWORKS Rocketry (VSWR), we flew 3 flights with a difference in altitude no more than 15 feet with our latest Mk4.3 airbrake system and full-config firmware inside the rocket.. We are now using a parachute minimizer system to tune descent rates and keeping the rocket's mass a constant 636g.

We flew two flights out of DART using the Zenith 3A vehicle. However, the airbrake-transition unit (Mk3.2) broke due to excessive shock cord flights. With the ABS out of operation, we will work on the Mk4 version for our last practice launch date on 3/13/2022. We did test a new firmware system that allows the Flight Computer to not only write to the rocket's SD card, but also read configuration values off it. This system will be expanded to include more variables to tune flight.

We tested the Zenith 4 to its limits in high winds at our first launch at ROC. Flights showed promise in our airbrake system but our turnaround times for the complex launch vehicle were around 40 minutes. Using these issues, we practiced turnaround times to get the highest launch throughput out of our rockets.

Horizons has finished its pinnacle launch systems of Zenith 3 and 4, along with 2 additional backup boosters (a refurbished Booster 3 and Booster 8). These final rokets will be used for the qualification flight and feature tangle-free deployment systems, the new FC5 and FC6 flight compute boards, and the Mk2.3 airbrake system to deliver precise flight capability. More build days in the future will be utilized to cut down on build turnaround.

Horizons has uploaded footage from the Zenith 2A Engineering Camera, used to ensure that airbrake and parachute systems were functioning correctly in flight. Realtime video was broadcasted onto our ground station and recorded.

Zenith 2A is a complete redesign of the core Zenith 1/1B elements of the Airbrake and internal avionics systems. The new ABS CORE is planned to save 30g of mass while offering 3x the torque and deep control capability to newer wide airbrakes.

In order to fabricate more advanced parts of different polymers of Zenith 2, Horizons upgraded its fabrication tooling with an overhaul of components. These upgrades will support flexible parts, as well as increased heat-resistant parts. Zenith 2 is on track for two launches in December, with 2 planned to be built. Major redesigns are focused in the airbrakes and internal structures. Subscale pathfinders are being considered for stability checks.

Using the newer and more advanced Zenith 1B, we tested a new payload bay design as well as parachute release for our dual deployment system on a slightly smaller test motor. The launch was a complete success including successful recovery, and we collected data to pursue upgrades to Zenith 1B on the launch date of next week. Our goals have now moved from safe recovery to fully utilizing our airbrake system and flight computer to hone in altitudes and flight duration.

Zenith 1B fixes key issues with Zenith 1, especially with payload mounting and SPRS. Horizons is planning on two launch dates on 11/13 and 11/21 to test its systems and shoot for a fully successful parachute recovery. After reliability and safety is achieved, efforts will be focused on refining altitude-control software.

With our first operational TARC rocket, Zenith, we tested our new airbrake system, parachute dual-deployment, and our much more powerful Flight Computer 4 on the Zenith 1 vehicle. The launch was a partial success with no loss of vehicle, though the mains did not deploy due to an umbilical cord disconnect.

Team Horizon members met up to learn how to launch their own kit rockets and the TARC launch procedure with our Zoomer preseason prototype rockets, with the partially successful launch of Zoomer 2 at Vocational STEAMWorks Rocketry with a failure of the main parachute to deploy from the nose housing.

In partnership with the San Diego Public Library, Together We Shine ran virtual workshops on basic rocketry and provided hands-on kits. TWS Horizons provided launch supplies and hosted an optional workshop launch at Vocational STEAMWorks Rocketry.

After the workshop launches were concluded, two flights of Zoomer 1 were made with a failure and then a success.

With the closure of most launch sites due to the pandemic, Team Horizons began a series of drone-assisted testing for Zoomer hardware and testing out its software. There were 5 flights in total between 100'-200': one tethered flight of Zoomer 1's flight computer and four drop tests of Zoomer 2's flight computer along with Parachute Deployment System hardware.

There were some early failures, but in the end the flight computers and PDS were made reliable enough to be cleared for launch.
