The 9/11 Memorial Museum's Memorial Exhibition will commemorate the lives of the people killed on September 11, 2001, and February 26, 1993, allowing visitors to know more about the women, men and children, who perished in those attacks. Plans for the museum allows visitors to enter the exhibition along a corridor in which portrait photographs of the nearly 3,000 victims form a "Wall of Faces" that is intended to try and communicate the scale of human loss.

As part of the exhibition, interactive tables are planned that will allow visitors to discover more information about each person, including additional photographs, remembrances by family and friends and artifacts. An adjoining space will present profiles of individual victims in a dignified sequence through photographs, biographical information, and audio recordings. Every victim's name will be read aloud within the memorial exhibition. These spoken names will be professionally recorded by a group of volunteer family members. If you are interested in contributing your time and voice to this group, please contact us.

The memorial exhibition relies on materials contributed by you. Learn more here.

9/11 Memorial President Joe Daniels was prompted to reach out to 9/11 Memorial supporters and attack victims' families after Iran President Mahmoud Ahmadinejad gave a politically-driven speech about the 2001 terrorist attacks at the U.N. General Assembly yesterday in Manhattan. Ahmadinejad's calculated and incediary remarks  caused U.S. officials to abrutly walk out.

In the letter Daniels penned in response to the remarks, he said Ahmadinejad's words "was a grievous insult to the families and friends of those who lost their lives that tragic Tuesday, as well as to a nation and world that remain outraged by the indefensible terrorist attacks perpetrated by al Qaeda."

Daniels also spotlighted in his letter one of the chief purposes of the National September 11 Memorial & Museum, which is to dispute lies such as Ahmadinejad's and for to lead in the "preservation and presentation of the authentic history of what occured on 9/11."

Read Daniels' entire letter online in the Huffington Post.

Up all night:  The 9/11 Memorial's Ron Vega and Kim Cases recently reviewed plans for the planting of the first of 16 trees planned for the memorial's plaza. Vega, the director of design and construction, and Cases, the assistant project manager, have played this scenario out for months, even years.  The first trees have been successfully planted and are growing strong.

New York City Mayor Michael Bloomberg, who serves as the board chair of the National September 11 Memorial & Museum, delivered the following remarks on the steps of the U.S. Capitol yesterday as part of a September 11th Remembrance Ceremony:

"Remember, reflect, rebuild. That’s what we’ve been doing for nine years, and I’m here to say thank you to America, to people from all 50 states who have helped us do that, and to commit to this country that we will not forget our obligation to work with the rest of the country to take care of those who came to our aid – first as a rescue mission, and much too rapidly turning into a recovery mission. And we will not forget our obligation to educate our children and our grandchildren that our freedoms are fragile, and the young men and women overseas who are fighting and dying to let us continue to speak and to pray and to live the way we want to live – we will not forget ever."By 9/11 Memorial Staff

A volunteer organization born out of the 9/11 is helping to coordinate one of the largest volunteer service events in Arkansas. Earlier this month, The New York Says Thank You Foundation worked jointly with the Polk County Arkansas Long Term Recovery Committee and the Polk County 4-H Foundation to bring hundreds of volunteers from New York City and across the country to help rebuild Mena, Ark.

The rural town is about 140 miles west of Little Rock, Ark., the state's capitol city.  The town was devastated by a tornado on April 9, 2009 that killed three of the town's residents. Hundreds of homes were destroyed and damaged. To mark the 9th anniversary of 9/11, New York Says Thank You partner with the local organizations and volunteers across the country to help rebuild the town.

Jeff Parness of New York Says Thank You is traveling the nation to restore a U.S. flag recovered from ground zero. Ashen, tattered and blowing in the wind, the torn flag was recovered after the World Trade Center crumbled.  The flag was stitched back together several years later and grew into a symbol that reinforces the same commitment to service and volunteerism experienced across the country and world on Sept. 12, 2001.

On the ninth anniversary of the 9/11 attacks, the flag will embark on a national tour to be restitched to its original glory. The first stop for the National 9/11 Flag was Mena.

After the flag makes its journey across America, it will return to New York City, where it will be added to the permanent collection of the 9/11 Memorial Museum.
