I'm planning a visit to the Goddard Space Flight Center Visitor Center. Can you tell me its operating hours for general admission, if there's an admission fee, and the best phone number to call for general inquiries about visiting?
Navigate to pao.gsfc.nasa.gov. Click on the 'Visit Goddard' button in the main navigation. On the 'Visit Goddard' page, locate the 'Hours of Operation' and extract the general admission hours. Determine if there is an admission fee for general visitors. Find the phone number for general inquiries related to visiting the center. Synthesize all collected information into a concise answer.
The agent successfully navigates to the 'Visit Goddard' page. The agent states the general admission hours as 'Tuesday through Friday: 10 a.m. – 5 p.m.' and 'Saturday and Sunday: 10 a.m. – 4 p.m.'. The agent correctly states that 'Admission is free'. The agent provides the general inquiry phone number as '301-286-8981'.
