21 Challenges: We are deeply involved with several projects of high scope, with large scientific and technological potential How to maximize the scientific and technological return for all Astronomy in São Paulo? We have an enormous opportunity! We need people: post-docs, senior scientists, engineers We need labs for instrumentation that promotes innovation We need to use this opportunity to improve the scientific culture of our students and of the society as a whole We need to engage our community in a Plan to take advantage of this opportunity for the Astronomy in São Paulo 21
