Upcoming Launch of Falcon 1

According to a press release from SpaceX, they are planning on launching their next flight of Falcon 1 on April 20, 2009:

Hawthorne, CA (March 30, 2009) – Space Exploration Technologies (SpaceX) announces that the launch window for ATSB's RazakSAT on Falcon 1 Flight 5, is currently scheduled to open Monday, April 20th at 4:00 p.m. (PDT) / 7:00 p.m. (EDT).
SpaceX's Falcon 1 launch site is located approximately 2500 miles southwest of Hawaii on Omelek Island, part of the Reagan Test Site (RTS) at United States Army Kwajalein Atoll (USAKA) in the Central Pacific. Due to the location of the launch site, the Kwajalein local date at the opening of the launch window will be April 21st.

RazakSAT was designed and built by Astronautic Technology (M) Sdn Bhd (ATSB), a pioneer and leader in the design and manufacture of satellites in Malaysia. The satellite will be launched aboard the Falcon 1, a two-stage, liquid oxygen/rocket-grade kerosene vehicle, designed from the ground up by SpaceX.
Falcon 1 will place RazakSAT, equipped with a high resolution Medium-Sized Aperture Camera (MAC), into a near equatorial orbit. The payload is expected to provide high resolution images of Malaysia that can be applied to land management, resource development and conservation, forestry and fish migration.

SpaceX will provide live coverage of the Falcon 1 Flight 5/RazakSAT mission via webcast at: www.SpaceX.com. The webcast will begin 20 minutes prior to launch and will include mission briefings, live feeds and launch coverage from the launch site. Post-launch, video footage and photos will be available for download on the Web site.
