ARK Reusable Rockets Research | 2025 Year-End Review

Key Concepts

• Reusable Rockets: Rockets designed to be used multiple times, significantly reducing launch costs.
• Launch Cost Decline: The dramatic decrease in the cost of sending payloads into space.
• Geosynchronous Orbit (GEO): An orbit approximately 22,000 miles above Earth, offering wide coverage but with high latency.
• Low Earth Orbit (LEO): An orbit a few hundred miles above Earth, characterized by lower latency and requiring more satellites for global coverage.
• Direct-to-Device Capability: The ability for smartphones to connect directly to satellites for communication.
• Space Supremacy: The dominance of one nation or entity in space capabilities, encompassing both defense and commercial aspects.

Reusable Rockets and Cost Declines

The reusable rocket sector is characterized by a dramatic cost decline, fundamentally altering the business model and creating significant opportunities. Historically, from the late 1990s to the early 2000s, rocket launch costs were increasing due to a duopoly in the US and reliance on Russia. SpaceX disrupted this trend by focusing on rocket reusability, a concept initially met with skepticism. SpaceX successfully landed its first rocket in 2015 and reused it in 2017, establishing a ten-year lead in orbital rocket reusability. This lead has allowed them to consistently reduce launch costs through improved refurbishment and shorter reuse timelines. While other companies are now recognizing the importance of reusability for cost reduction, none have yet achieved orbital rocket reuse.

Enabling New Opportunities in Space

The reduction in launch costs has opened up new possibilities in space, particularly in Low Earth Orbit (LEO). Previously, the focus was on Geosynchronous Orbit (GEO), approximately 22,000 miles above Earth. Satellites in GEO can cover a third of the Earth, requiring only three massive, expensive satellites for global coverage. However, the long distance results in high latency, making it unsuitable for many applications.

LEO, situated just a few hundred miles above Earth, offers significantly lower latency. The challenge in LEO is that satellites are constantly moving relative to Earth and cover a smaller area. This necessitates launching dozens to tens of thousands of satellites for global coverage, which would be economically unfeasible with high launch costs. The declining launch costs have made LEO constellations viable, enabling applications like high-speed internet.

Starlink and Direct-to-Device

Starlink exemplifies the opportunities in LEO, providing high-speed internet from its orbiting satellites. The speaker shared a personal experience testing the Starlink Mini, highlighting its ease of setup, taking only 15-20 minutes from unboxing to operational use.

This shift is projected to create a $130 billion annual revenue opportunity. Key components of this opportunity include:

• Global Broadband: Providing internet access to individuals and businesses.
• Direct-to-Device Capability: Enabling smartphones to connect directly to satellites. This offers emergency text capabilities and off-grid coverage, not necessarily replacing traditional telcos but augmenting them. T-Mobile has indicated a potential $10-$20 per month charge for this service. The speaker estimates that at $0.50 per month, 8 billion cell phone subscribers could contribute to a $48 billion opportunity.
• Broadband for various users: This includes households ($40 billion opportunity), RVs, boats, aircraft, and ships.

Current Developments and Future Outlook

While the direct-to-device and broadband opportunities remain the most significant, several other developments are noteworthy:

• Starlink and T-Mobile Service Launch: The direct-to-device service was launched in July.
• Mach 33 Collaboration: ARC collaborated with Mach 33 on an open-source valuation of SpaceX, providing a detailed analysis of its potential over the coming years.
• Starship Testing: Continued testing of SpaceX's Starship has yielded impressive results and valuable learnings, despite some notable explosions.
• Lunar Lander Missions: Companies like Intuitive Machines and Firefly have conducted lunar lander missions. Firefly has also gone public, entering the public investment landscape.
• Competitive Landscape: A decade after SpaceX's breakthrough, other companies like Blue Origin (which successfully launched a rocket to orbit but did not reuse it) and Rocket Lab (progressing on its Neutron reusable rocket) are still striving to achieve reusable orbital launches.
• Space Race: A heated space race is underway, particularly concerning the Moon, with China being a significant player.
• Space vs. Defense: While defense has seen a substantial tailwind due to geopolitical events, space has continued its rapid advancement. This trend is expected to persist, driven by the pursuit of space supremacy for defense purposes and commercial advancements in LEO, the Moon, and potentially Mars.

The speaker concludes by noting that even in an industry perceived as slow-moving, space is experiencing rapid progress, with further updates anticipated in "Big Ideas 2026."
