The 22nd OBA will be held on May 17 at participating schools, with tests comprising seven questions from Astronomy and three from Astronautics.
The medals of the Brazilian Astronomy and Astronautics Olympiad will be distributed according to the score obtained by the participants of each level.

Do not stop now... There's more after the advertising ;)
How to study for the OBA?
The study material for the OBA can be seen in the “Simulado OBA” application and by the videos, tests and templates from previous editions that are in the Olympics website.
13th Brazilian Rocket Show
Registration for the 13th Mostra Brasileira de Rockets (MOBFOG) is also open until March 17th. Participation is made by the registration with the OBA, on the same site, with the organization of the event being the responsibility of the Brazilian Astronomy and Astronautics Olympiad itself.
Participants will have to make rockets out of a paper tube, plastic straw or pet bottle and launch them as far as possible. The projects that reach more than 100 meters will have their students invited to the Jornada de Foguetes, an event to be held in Barra do Piraí/RJ.
The Rocket Show will award all participating teachers, principals and students with certificates of participation, plus medals for students with the best rockets results.

Physics
Do you know what an astronomical unit is? It is a measure of length that uses as a reference the average distance from the Earth to the Sun. An astronomical unit is equivalent to approximately 499 light seconds, that is, the distance traveled by light in a vacuum in 499 seconds, or even about 150 million kilometers.
