I would not have been able to complete any research in the astronomy of the skies of 2000-years ago had I not received the shipment of astronomy programs from NASA. I used every one many times before beginning my research. I have been pleased to learn readers of my book, Unraveling the Christmas Star Mystery, have been able to confirm data in the book. 

Below is the list of astronomy programs I received from NASA many years ago. They were used in my classrooms by students doing independent study, completing research for class or extra credit, homework/classwork, make up work, and as assigned work. When students were in study hall, they were given permission to come to my science classroom and use the NASA programs on the computers as long as they didn't disturb the class in progress. Many students took advantage of the few computers we had.

I did not know these programs existed until they were received from what is now the NASA Space Center-Houston educational office. NASA educational materials were often requested and received for my class use. They were kept on file and used year after year as class sets by many teachers. The school and public libraries kept many lithographs, photographs, booklets and Fact Sheets in their vertical files.

My students were thrilled with the materials received from NASA, especially the Fact Sheets and photographs. The astronomy programs were considered phenomenal for my students loved astronomy. There was one senior student who told me there had been only one person in his life with whom he could discuss astronomy. When I asked who that was, he responded, "You." That was a thrill. I was pleased to learn he planned to enter the field of astronomy. I understand he is currently a professional astronomer.
