        <ExplanationTxt>The AAS engages in limited lobbying activity, the largest event being one day of congressional office visits by AAS members in DC that occurs in the spring, in which AAS members visit the offices of their senate and house members and advocate for science funding. AAS also facilitates member visits to their local congressional offices in the summer recess. The AAS also submits written testimony to appropriations committees in the spring for NASA and the National Science Foundation, and lends our name to coalition letters for increased R&amp;D funding or other broad science policy or science education topics. Similarly, AAS asks their members a few times a year to contact their members of congress on budget or other issues. On rare occasions, other specific issues arise in which AAS staff make contacts with congressional or executive branch staff to express the opinion of the society.</ExplanationTxt>
