Arrangements and details are trickling out:

The official tributes and funeral services for Senator Edward M. Kennedy will begin on Thursday morning, when his body is carried by motorcade from the family compound in Hyannis Port to the John F. Kennedy Presidential Library and Museum just outside Boston.

Once the trip is completed, his body will lie in repose at the library for public viewing, and then again on Friday, from 10 a.m. to 4 p.m.

From 7 to 9 p.m. Friday, there will be a memorial service that is closed to the public. We’re told that Vice President Joseph R. Biden and Senators John Kerry and John McCain are among the notable featured speakers.

On Saturday morning, a funeral mass will be held at Our Lady of Perpetual Help Basilica in Boston. President Obama is expected to speak at the mass. Afterward, Senator Kennedy’s body will be carried by plane to the nation’s capital, and taken to Arlington National Cemetery, where a burial ceremony will take place at 5 p.m. (The mass and burial are closed to the public.)

Both Senator Kennedy’s brothers, John and Robert, are buried in Arlington, and the senator will be laid to rest near them.
