Brigadier Gen. William D. R. Waff, deputy commanding general of the 99th regional readiness command, Centre County District Attorney Michael Madeira, Pastor Tom Jacobs of United Methodist Church and Commander Barbara Spencer will also address the Old Main crowd during the morning memorial.
The bells of Old Main will ring four times today to remember each plane crash: 8:46 a.m., 9:03 a.m., 9:37 a.m. and 10:03 a.m.
Another memorial, The Good Deed Mitzvah Marathon, organized by the Chabad Jewish Student Organization and Chabad of Penn State, will run from 10 a.m. to 4 p.m. at the Allen Street Gates.
Pieces of paper bearing the name and photo of victims of the Sept. 11 attacks will be strung across the gates, creating a "wall of honor."
The pieces of paper have a blank space that community members can then fill in with some sort of good deed they will perform as a tribute to the victim of the Sept. 11 attacks.
"By taking on a good deed you are bringing light to the darkness of the negativity and evil of the world," said Rabbi Nosson Meretzky.
At 12:45 p.m., bystanders will join the group to observe a moment of silence for those who were affected by the Sept. 11 attacks.
Last year, the former Chabad president Jenn Putterman said about 400 people stopped by or attended the fourth anniversary memorial.
Meretzky said he expects between 500 and 600 participants to stop by the area this year.
"The fact that it's the fifth year since the attacks is of significance," Meretzky said. "We need to keep these people in mind."
