In early 2021, SpaceX achieved a groundbreaking mission that set new records in space exploration. Among the unique aspects of this mission was the inclusion of human ashes sent to low Earth orbit, a service provided by Celestis. This company even offers to send ashes to the Moon for $12,500, which is relatively affordable in the context of space travel. However, the most remarkable feat of this mission was launching 143 satellites into orbit, surpassing the previous record of 104 satellites set by India.
This mission was part of SpaceX’s innovative ‘Rideshare’ program, which allows smaller satellites to hitch a ride with larger ones, significantly cutting costs. Historically, launching a 500 kg satellite was extremely expensive due to the absence of affordable reusable rockets. Satellite owners had to bear the full cost of building and launching a rocket. In the past, satellites were large and cumbersome, designed for specific tasks, and the technology that fits in our pockets today once filled entire rooms in the 1960s and 70s.
Technological advancements have enabled the creation of much smaller satellites at a fraction of the previous costs. This has fueled the rapid expansion of the small satellite industry. “Small sats” are generally defined as satellites under 500 kg, while “nanosatellites” are those under 50 kg. One of the most successful nanosatellite types is the CubeSat, consisting of 10 cm modules that are highly customizable. These satellites allow companies to conduct space research that would otherwise be prohibitively expensive. CubeSats are often launched to the International Space Station and deployed from there.
Over the past decade, the number of CubeSats launched has surged, and their popularity is expected to continue rising. With reduced costs, many satellite operators have shifted from traditional government rockets to the more affordable and reliable SpaceX. However, in recent years, demand for large communication satellites has decreased, resulting in fewer customers for SpaceX.
Meanwhile, Rocket Lab has emerged as a competitor with an increasing launch schedule, offering dedicated launches at a fraction of SpaceX’s costs. While a Falcon 9 launch costs at least $50 million, Rocket Lab charges around $7 million per launch, making it a more attractive option for small satellite launches. To stay competitive, SpaceX introduced its rideshare program, offering 200 kg slots on the Falcon 9 for $1 million each, which is still cheaper than Rocket Lab’s offerings.
For smaller satellites, companies can share their slots on the Falcon 9, creating a “rideshare within a rideshare.” Spaceflight Inc., for example, offers CubeSat slots for as little as $150,000. This innovative approach has made space more affordable and accessible, with a user-friendly booking system that allows customers to select their desired orbit, mass, and scheduled flights.
Despite the high costs, SpaceX’s rideshare program remains the most cost-effective way to launch satellites into orbit. The Falcon 9’s reusability enables SpaceX to undercut competitors while maintaining profitability. Additionally, SpaceX’s overall launch frequency has increased, largely due to the launch of its own Starlink satellites, which aim to provide high-speed internet globally.
Each Starlink satellite is estimated to cost around $250,000, significantly lower than traditional satellites. With plans to launch thousands of these satellites, the rideshare program plays a crucial role in managing costs. During its first official rideshare launch, SpaceX included 10 Starlink satellites, effectively reducing launch costs for other customers.
While SpaceX’s rideshare program competes with Rocket Lab, it has not significantly impacted their business. Rideshare missions require all satellites to wait until the rocket reaches full capacity, which can lead to scheduling conflicts for customers. Rocket Lab offers dedicated launches, and as they work towards reusing their rockets, they may become more competitive with SpaceX.
Looking ahead, SpaceX’s future plans include the Starship, a fully reusable rocket with a payload capacity that far exceeds current options. Starship could potentially launch 240 Starlink satellites in one go, with estimated launch costs around $2 million, which could drastically reduce the cost per 200 kg slot for rideshare missions.
Ultimately, all of these advancements contribute to SpaceX’s overarching goal of enabling human exploration of Mars, with every financial and technological gain supporting this vision. The company’s innovative approaches to satellite launching are paving the way for more affordable and accessible space exploration, bringing us closer to the dream of interplanetary travel.
