ETA-8 Announcement

The ETA-8 Rocket ( Watch the Announcement Here ) will be our first Class B launch vehicle, capable of around 15t to LDO. This rocket was designed to meet the greatest standards for reliability, price, and launch cadence. Powered by 8 of our world class HZ-270, Staged Combustion Cycle Methalox engines, it is capable of putting most payloads into their desired orbits.

At Sirius, We want our vehicles to be on-par with the greatest in the area, and to accomplish this, we are introducing a capability that is currently unknown to the rocket industry: True Reusability. The SAT team is led by multiple engineers who have experience working with this concept — and succeeding at it — we also have some of the most well known Software Developers on board the project. The goal is to be able to refly each of the ETA-8 cores at least 5 times. Initially, we expect to have a launch cadence of 2 to 3 launches per month, hopefully increasing that as time goes on. Initial launches for ETA-8 will start around Mid April, and we hope to let customers book rides for launches starting in Late April to May.
