The long term health of the Society depends on a culture of membership that starts with undergraduate and graduate students. AAS Agents can work with departments to ensure all students can join the Society.
Undergraduates can join for just $41, or they can get a free membership by joining their local chapter of the Society of Physics Students for $24.
Agents can help support membership for graduate students by encouraging their departments to participate in a special program offered by the AAS: if a department supports 2 years of a graduate student's member dues ($144), the AAS will match this and offer four total years of membership.
This would be a concrete symbol of welcoming students to the profession while establishing membership as an important (and routine) part of being an astronomer, astrophysicist, planetary scientist, dynamicist, heliophysicist, etc.
