Arianespace has announced that it will launch BSAT-4b as part of a turnkey contract between Japanese satellite operator B-SAT and Maxar’s California-based satellite manufacturer SSL. Since the creation of B-SAT, Arianespace has launched all nine of its satellites. BSAT-4b not only marks the 10th launch but also the 32nd commercial geostationary satellite launch contract awarded to Arianespace in Japan.

Built by SSL using a 1300 platform, BSAT-4b will feature 24 Ku-band transponders. It will weigh about 3,520 kg at launch and is designed to have a nominal service life of at least 15 years. It will be positioned in geostationary orbit at 110 degrees East. BSAT-4b will serve as a back-up of BSAT-4a, which Arianespace launched in September 2017. It will have the same Japanese archipelago footprint as BSAT-4a, providing Direct-to-Home television to ensure 4K/8K ultra-high definition video distribution for the 2020 Tokyo Olympic Games.

SpaceX’s Transporter-17 Mission Launches 81 Payloads

SpaceX launched 81 payloads on the latest launch in its rideshare series, Transporter-17. The mission launched early Tuesday morning from Vandenberg Space Force Base in California on a Falcon 9 rocket, taking off at 12:12 a.m. PT (3:12 a.m. ET). 

The mission had a number of notable milestones onboard, including the first Nova satellite from Apex Space, which is set to demonstrate the Nova platform architecture. 

Another first included the tech demonstration satellite for Planet’s second-generation Pelican fleet, Pelican-11. 

It included the first operational satellites of the Earth Fire Alliance’s (EFA) FireSat constellation, built by Muon Space. These satellites are designed to identify early wildfire ignitions and track active fires. 

French radio frequency detection company Unseenlabs launched the first satellite in its second-generation (Gen 2) constellation, built to expand its RF detection capabilities to multi-domain awareness spanning maritime, land, and space.

Another interesting first onboard was City Lab’s BOHR satellite, which the company called the world’s first commercial nuclear-power satellite and first nuclear cubesat. The mission will use City Labs’ NanoTritium betavoltaic technology in orbit as a dedicated payload power source. 

NearSpace Launch, Inc. (NSL) launched three satellites in the SPEAR-1 mission to support U.S. national security. 

Open Cosmos had two satellites on the mission, Posidònia, the first satellite of the Balearic Islands, and Hyperion GR-1 the first of seven satellites for Open Cosmos’ Greek constellation.

Spire Global had 10 Lemur-2 satellites onboard for various customers including three for Deloitte

Rideshare integrator Exolaunch deployed 49 customer satellites on the mission, including four satellites for Iceye

Another rideshare integrator SEOPS integrated 10 customer spacecraft, including a satellite for FOSSA Systems, the NearSpaceLaunch satellite, and R5 Spacecraft 9, which comes from a partnership between Sandia National Laboratory and NASA.
