Stoke Space’s approach to full reuse is easiest to understand when you can actually see the hardware. During an exclusive post-Series E tour of the company’s 168,000-square-foot headquarters outside Seattle, CEO Andy Lapsa walks us through the evolution of Nova—from the Hopper demonstrator that first proved Stoke’s second-stage architecture to the flight hardware now being prepared for orbital testing.

We cover:
How Stoke is scaling Nova from the three-ton Pathfinder to the 15-ton Block 2
• What changes and what stays the same in Block 2’s propulsion architecture
• How Stoke plans to ramp Pathfinder production while developing Block 2 in parallel
• What remains before Pathfinder ships for final testing and its first orbital flight
• Why Stoke is expanding its manufacturing and testing footprint following the $1 billion Series E

…and much more…
