BANGABANDHU SATELLITE-1 Mission
Mission Overview:
SpaceX is targeting launch of Bangabandhu Satellite-1 on
Thursday, May 10 from Launch Complex 39A (LC-39A) at
NASA’s Kennedy Space Center, Florida. The launch window
opens at 4:12 p.m. EDT, or 20:12 UTC, and closes at 6:22
p.m. EDT, or 22:22 UTC. Bangabandhu Satellite-1 will be
deployed into a geostationary transfer orbit (GTO)
approximately 33 minutes after launch.
A backup launch window opens on Friday, May 11 at 4:14
p.m. EDT, or 20:14 UTC, and closes at 6:21 p.m. EDT, or
22:21 UTC.
The Bangabandhu Satellite-1 mission will be the first to
utilize Falcon 9 Block 5, the final substantial upgrade to
SpaceX’s Falcon 9 launch vehicle. Falcon 9 Block 5 is
designed to be capable of 10 or more flights with very
limited refurbishment as SpaceX continues to strive for
rapid reusability and extremely high reliability.
Following stage separation, SpaceX will attempt to land Falcon 9’s first stage on the “Of Course I Still
Love You” droneship, which will be stationed in the Atlantic Ocean.
Payload
Bangabandhu Satellite-1 is Bangladesh’s first geostationary communications satellite. Development of
the satellite program, known as the “Bangabandhu Satellite Launching Project,” was managed by the
Bangladesh Telecommunication Regulatory Commission (BTRC) with technical support from Space
Partnership International (SPI). The satellite, which is comprised of 26 Ku-band and 14 C-band
transponders, was manufactured by Thales Alenia Space on the Spacebus 4000B2 platform and will be
operated by the Bangladesh Communication Satellite Company Limited (BCSCL).
Bangabandhu Satellite-1 has a primary service area encompassing Bangladesh and the surrounding
region. The satellite will offer Ku-band coverage over Bangladesh and its territorial waters in the Bay of
Bengal, as well as India, Nepal, Bhutan, Sri Lanka, the Philippines, and Indonesia. It will also provide Cband capacity for the entire region.
Located at 119.1° East, Bangabandhu Satellite-1 will provide direct-to-home (DTH) services, video
distribution and very small aperture terminal (VSAT) communications across Bangladesh. The satellite
will also provide broadband connectivity to rural areas throughout the country. Bangabandhu Satellite-
1’s mission is expected to last at least 15 years.

Launch Facility
Launch Complex 39A at Kennedy Space Center, Florida
Launch Complex 39A at NASA’s Kennedy Space Center has a long and storied history dating back to the
early 1960s. Originally built to support the Apollo program, LC-39A supported the first Saturn V launch
(Apollo 4), and many subsequent Apollo missions, including Apollo 11 in July 1969. Beginning in the late
1970s, LC-39A was modified to support Space Shuttle launches, hosting the first and last shuttle
missions to orbit in 1981 and 2011 respectively.
In 2014, SpaceX signed a 20-year lease with NASA for the use of historic Launch Complex 39A. Since
then, the company has made significant upgrades to modernize the pad’s structures and ground
systems, while also preserving its important heritage. Extensive modifications to LC-39A have been
made to support launches of both commercial and crew missions on SpaceX’s Falcon 9 and Falcon Heavy
launch vehicles.
