Building for life in space.



On-Orbit Update: Vehicle commissioning is underway and customer payload deployments have begun on the LEO Express 3 Mission. After separation from the launch vehicle, our team used new, Impulse-built radios to make contact with Mira. The spacecraft autonomously deployed its new dual solar arrays and established a sun-pointing attitude and power-positive state. During the initial phase of our commissioning process, Mira’s star trackers produced noisier measurements than expected, leading to higher RCS propellant expenditure than desired for this phase of the mission. After detecting this trend, our team pivoted to an alternate attitude control scheme and is continuing to proceed through additional commissioning activities. Having expended the majority of the nitrous oxide as a result of the incident, Mira will not be able to perform main thruster burns. We’ve also begun LEO Express 3 customer missions, with 2 of 3 FOSSASats successfully deployed into their target orbits. Mira remains in a stable, sun-pointed and power-positive state.

Successful orbit insertion. Zenno Supertorquer has been deployed into its planned orbit aboard Impulse Space Mira, launched by a SpaceX Falcon 9. We are now moving into the next phase of the mission and will run operations over the coming months.





Mira is getting ready for launch! Our spacecraft for the LEO Express 3 mission has officially left our building ahead of the upcoming Transporter-15 rideshare mission with @SpaceX. This marks another key milestone as we move toward launch.
