I was lucky enough to get out to Norway last month, to see the latest hybrid rocket firing at Nammo's test range.
Nammo is developing a prototype rocket which will one day power the next generation of satellite launchers.
Meanwhile, the safety benefits of hybrid technology means that it's perfect for Bloodhound.
As a result, if you'll forgive the pun, we're the "launch customer" for Nammo's new rocket.
The impressive thing about watching the Nammo test was just how measured and controlled everything was.
For a prototype rocket test, they made it look easy.
