WASHINGTON – NASA will host a media teleconference on Wednesday, April 11 at 2 p.m. EDT to discuss science objectives of the Aeronomy of Ice in the Mesosphere (AIM) mission.

AIM is scheduled to launch April 25 from Vandenberg Air Force Base, Calif., aboard a Pegasus launch vehicle. It will measure high altitude noctilucent (“night shining”) clouds to determine why they form and vary, which may be linked to climate change.

Briefing participants are:

— Vicki Elsbernd, AIM Program Executive, NASA Headquarters, Washington

— Jim Russell, AIM Principal Investigator, Hampton University, Hampton, Va.

— Chris Savinell, AIM mission manager, Goddard Space Flight Center, Greenbelt, Md.
