Education as a mission purpose
PION-BR1 was a small Brazilian startup mission with amateur-radio and education goals. Its project description proposed a digital experiment, activities and investigations of the spacecraft environment. AEB records its January 2022 launch but states that it did not operate because of a failure. Those two facts can coexist: successful carriage into space is not the same as successful execution of the payload’s planned activities.
PION-BR2, also called Cientistas de Alcântara, brought an educational partnership involving UFMA, AEB, the United Nations Development Programme and PION. It was carried on the December 2025 Hanbit-Nano attempt that failed to reach its intended mission outcome. The national register lists a launch failure. Describe the students’ intended participation respectfully without turning a planned message transmission into an event that actually occurred in orbit.

Follow a message instead of assuming delivery
A store-and-forward system receives a message, retains it and sends it onward when an appropriate opportunity occurs. For an original classroom simulation, label three messages A, B and C. The receiver logs A twice and C once, but never B. There are three receptions and only two distinct messages. Counting packets without identifiers would conceal that missing message and overstate the completeness of the exchange.
The exercise should also preserve timestamps and content. A correctly decoded message can still arrive too late for its intended purpose, while a duplicate may improve confidence in delivery without adding a new observation. Define what success means before running the simulation: all unique messages received, content unchanged and delivery within a specified window. These are teaching criteria, not a claim about the actual results of either PION flight.
Check message identity and outcome

A failed flight does not erase the learning record
A mission team can preserve designs, ground-test results and lessons from integration even when the spacecraft never provides its intended orbital service. Those contributions should be described on their own terms. A ground demonstration may establish a working protocol under laboratory conditions; it cannot substitute for the missing evidence of radio operation, environmental survival or service performance in orbit. Honest distinctions make the educational record more useful.
For a final activity, create a timeline with separate rows for hardware preparation, launch, first contact and experiment results. Mark each item as documented, intended or not demonstrated. Add the questions a later team would need to answer before trying again. PION’s missions show why learning about space includes outcomes other than successful operations, and why careful records help future students build on experience without repeating unsupported claims about what a spacecraft achieved.
