External Payload Hosting (Bishop)

Nanoracks Bishop Airlock expands on our existing external payload hosting capabilities by offering 6 sites that accommodates larger payloads and provides an array of pointing options.  

Bishop gives the user the freedom to perform several tasks whether it’s for microgravity research, Earth Observation with several pointing options. Airlock operations are streamed in real-time in high-quality – not only for ensuring mission success but for customers that want to throw a launch party for their team and other stakeholders. 

Do you want to bring your payload outside the ISS?
Thanks to its 6 different sites outside the ISS, Bishop allows you to expose your payload under a vast range condition in the LEO orbit such as: Extreme heat and cold cycling; Vacuum; High-energy radiation environment. Bishop sets the standards to achieve higher TRLs or to reach new scientific and technological goals (IoD/IoV). In addition, there’s no limit to pointing options while attached to CanadaArm2. Zenith, Nadir, Ram, Wake – so feel free to tell us what you need.

Do you want to explore the most competitive and versatile solution?
We at Nanoracks Outpost Europe value your time and our wish is to focus on your needs. This is why we offer a versatile user-oriented programme. Host directly in the space environment, collect data, reduce risks and get to an operation programme faster and cheaper. Choose between 4-5 launch windows per year and shift this at little to no cost, all the way up to L-110 days, granting you a very flexible launch window with possibility for last minute preparation. Test our high reliability thanks to proven launch systems with well-defined schedules and less chance of launch delays. 

Don’t worry for disruptions.
Our services offer a sustainable approach allowing the user to do on the ground post-mission analysis of the effects of the space environment on hardware, including failure analysis. We dedicate insurance programmes re-flight in the event of failure.
