Sidus Space Moves LizzieSat-5 to Bandwagon-6

Sidus Space previously planned to launch LizzieSat-5 on SpaceX’s Transporter-18 mission in October 2026. However, the company shifted the satellite to Bandwagon-6 to expand testing of its Fortis VPX-Maxima platform. The additional work will test the system against broader requirements expected across future missions.

The company plans to assess Fortis across different environments, spacecraft designs, and mission interfaces before launch. This approach allows Sidus to complete wider qualification work within one testing period. It also reduces the need to repeat similar testing for individual spacecraft programs.

Both satellites will launch from Florida’s Space Coast, near Sidus Space’s Cape Canaveral production facility. The vehicles will move from manufacturing and testing operations directly to the launch site. Bandwagon-6 will place both spacecraft into a mid-inclination orbit after launch.

LizzieSat Spacecraft Carry Multiple Hosted Payloads

Sidus Space continues production of LizzieSat-4 before environmental testing and final mission preparation. The spacecraft will carry hosted payloads from Solar MEMS, Lonestar, and Maris-Tech. It will also carry imaging and maritime tracking equipment within Sidus Space’s own payload suite.

LizzieSat-5 has already completed environmental testing, including vibration testing at an Orlando defense testing facility. The spacecraft now awaits final integration before its planned 2027 launch. It will carry a hosted payload supplied by the Netherlands Organization for Applied Scientific Research.

Both satellites will also carry Simera Sense HyperScape-100 imaging systems and Satlabs Polaris AIS receivers. These systems support Earth observation and vessel identification functions during orbital operations. The mission will also provide more frequent coverage across mid-latitude regions than the earlier planned orbit.

Fortis Platform Supports Sidus Defense Pipeline

Sidus Space continues positioning Fortis for commercial and defense missions requiring stronger onboard computing capabilities. In July 2026, the company signed a teaming agreement with a commercial space contractor. The agreement includes Fortis as a proposed mission processor for an advanced orbital project.

That opportunity focuses on resilient, high-performance capabilities supporting national security mission requirements. Such programs require testing across processing, power, thermal, spacecraft, and data-handling specifications. Sidus therefore continues evaluating Fortis against wider system-level requirements before deploying the platform.

Sidus Space operates as an integrated space and defense technology company with manufacturing capabilities in Cape Canaveral. Its LizzieSat platform supports hosted payloads, imaging equipment, data processing, and other space-based applications. The planned Bandwagon-6 mission will extend that strategy through two additional spacecraft in 2027.
