Launch site: Baikonur
Launch date: May 21/22, 2009
The launch time is:
05:50:00 Kuala Lumpur 22.06.2009
03:50:00 Baikonur 22.06.2009
01:50:00 Moscow Local 22.06.2009

Payload: MeaSat-3a communication satellite
Spacecraft: MeaSat-3a
Manufacturer: Orbital Sciences Corporation
The MEASAT-3a satellite was developed and built for MEASAT Satellite Systems by Orbital Sciences Corp of Dulles, US. The satellite will carry 12 Ku-band and 12 C-band active transponders along with three antennas. MEASAT-3a will serve C-band markets throughout the region with a global beam, while Ku-band beams will serve direct-to-home broadcasting markets on Malaysia and Indonesia. The satellite will be located at an orbital slot at 91.5 degrees East Longitude over Southeast Asia and will generate approximately 3.6 kilowatts of payload power.

Launcher: Zenit-3SLB with DM-SLB upper stage
In place of the Boeing-made fairing used on Sea Launch, the Zenit-3SLB adopts a 4-meter fairing made by NPO Lavochkin. It is in current production and has been flight-proven with the Block DM.
Mission Profile
From the launch site at the Baikonur Space Center in Kazakhstan, a Zenit-3SLB launch vehicle will lift the 2,417 kg (4,448 lb.) MEASAT-3a spacecraft to geosynchronous transfer orbit, on its way to a final orbital location at 91.5 degrees East Longitude. The first stage will operate for two-and-a-half minutes and then jettison, followed by the jettison of the payload fairing three minutes later. After a six-minute burn, the second stage will separate from the Block DM-SLB upper stage. The Block DM will then begin the first of three burns, taking the spacecraft to a stable parking orbit. After a brief second burn, the upper stage will coast with the spacecraft for five hours, after which a third burn will inject the spacecraft into geosynchronous transit orbit. Eleven minutes later, the spacecraft will separate from the upper stage over the coast of Sumatera.
