The SpaceX Bandwagon-3 mission, launched on April 21, 2025, from Cape Canaveral’s Space Launch Complex 40, represents a monumental milestone in space exploration. Not only did it showcase SpaceX’s prowess in rideshare missions, but it also marked the 300th orbital flight from this historic launchpad. This achievement underscores the enduring legacy of Cape Canaveral as a pivotal site for space endeavors.
Bandwagon-3 successfully deployed multiple payloads into a mid-inclination orbit, highlighting the increasing demand for versatile and cost-effective launch solutions. The mission carried satellites for various purposes, including Earth observation, weather monitoring, and technology demonstration, further emphasizing the diverse applications of space-based assets.
This article delves into the details of the Bandwagon-3 mission, exploring the payloads it carried, the performance of the Falcon 9 rocket, and the broader implications for the future of space exploration and commercialization. From the South Korean military’s surveillance satellites to innovative re-entry capsules, we’ll uncover the significance of each component and its contribution to advancing our understanding of space and its potential.
Falcon 9’s Successful Launch and Landing
SpaceX achieved a remarkable feat by completing its third Falcon 9 rocket launch within a mere 48-hour timeframe. The Bandwagon-3 mission lifted off from Space Launch Complex 40 at Cape Canaveral Space Force Station at 8:48 p.m. EDT (0048 UTC), marking the 245th orbital launch for SpaceX from SLC-40 and the 300th total orbital flight from this historic pad. The Falcon 9 first stage booster, tail number 1090, successfully landed at Landing Zone 2, demonstrating its reusability for the third time, after the O3b mPOWER-E mission and Crew-10.
The landing at LZ-2 was only the 12th for the booster, compared to the 51 landings at LZ-1, showcasing the different operational patterns for SpaceX boosters. Weather conditions were highly favorable, with the 45th Weather Squadron forecasting a 95 percent chance of clear skies, similar to the conditions during the earlier launch of the CRS-32 mission from pad 39A. The precision and reliability of the Falcon 9, combined with favorable weather, ensured a smooth and successful launch and landing sequence.
The event highlights the importance of booster reusability in reducing the costs associated with space missions. This capability allows SpaceX to offer more competitive launch services, attracting a diverse range of customers and further driving the commercialization of space.
Korea 425 Project Satellite: Enhancing Surveillance Capabilities
Among the payloads onboard the Falcon 9 rocket was the fourth synthetic aperture radar (SAR) satellite for the Korea 425 Project constellation, destined for the South Korean military. This project, managed by Korea Aerospace Industries (KAI) under a KRW588 billion ($530 million) contract, aims to deploy a series of five surveillance satellites by 2025. The satellites are being developed through a collaboration between Korean firm Hanwha Systems Corporation (HSC) and Thales Alenia Space, with the latter serving as the prime developer.
Thales Alenia Space highlighted its contribution to the project, stating that it provided a high-performance SAR that utilizes an innovative antenna consisting of a large deployable reflector with 24 deployable petals and an active phased array feed array in dual polarization. Additionally, the company is responsible for the acquisition, storage, and data retransmission system on the ground. The satellites’ high agility is guaranteed by advanced avionics and Control Momentum Gyroscope, also provided by Thales Alenia Space, enabling high-performance observation and surveillance capabilities.
The Korea 425 Project underscores the growing importance of space-based surveillance for national security. The SAR technology allows for high-resolution imaging of the Earth’s surface, regardless of weather conditions or time of day, providing crucial intelligence for military and strategic purposes. The launch of this satellite contributes to the enhancement of South Korea’s defense capabilities and its ability to monitor potential threats.
Tomorrow.io’s Tomorrow-S7 Satellite: Advancing Weather Monitoring
Sharing the Falcon 9 with the Korea 425 Project satellite was the Tomorrow-S7 satellite, developed by Tomorrow.io. This 6U CubeSat, part of the Tomorrow Microwave Sounder series, is designed to operate in low Earth orbit at an altitude of 515 km (320 mi) with a 45-degree inclination. With a dry mass of 12 kg (26.5 lbs), the satellite is expected to have a three-year operating life and observe all-weather temperature and humidity profiles.
According to the Observing Systems Capability Analysis and Review Tool (OSCAR), part of the World Meteorological Organization, the Tomorrow-S7 satellite is the ninth spacecraft in the Tomorrow.io constellation and the seventh in the Tomorrow Microwave Sounder series. There is a possibility that a second sounder satellite from Tomorrow.io was also onboard the Bandwagon-3 mission. The Tomorrow-S7 satellite is part of a constellation designed to improve weather forecasting by providing more accurate and timely data on atmospheric conditions.
The launch of the Tomorrow-S7 satellite demonstrates the increasing use of small satellites for weather monitoring and forecasting. These CubeSats can be deployed in large numbers to create comprehensive observation networks, providing valuable data for meteorologists and climate scientists. The data collected by the Tomorrow.io constellation has the potential to improve weather predictions, helping communities prepare for extreme weather events and mitigate their impact.
Atmos Space Cargo’s Phoenix Capsule: Pioneering Re-entry Technology
The Bandwagon-3 mission also carried Atmos Space Cargo’s Phoenix capsule, marking a significant step forward in re-entry technology. The German company received permission for this mission from the Federal Aviation Administration (FAA) in January, making it the first private company in Europe to receive such authorization and the first non-governmental entity in European history to attempt space re-entry. The Phoenix 1 mission is designed to complete two orbits around Earth before making its atmospheric re-entry, gathering data about the capsule’s inflatable heat shield.
The mission has three core objectives: collecting in-flight data from the capsule and sub-components in orbit, gathering scientific data from customer payloads carrying technology demonstrators and biological experiments, and successfully deploying and stabilizing the Inflatable Heat Shield during atmospheric re-entry. Onboard the spacecraft are four payloads from three customers: DLR from Germany, IDDK from Japan, and Frontier Space from the United Kingdom. The mission trajectory was adjusted, with the re-entry beginning over Los Angeles, California, extending across South America, and resulting in a splashdown about 2,000 km off the coast of Brazil in the Atlantic Ocean. The Atmos Mission Control team will attempt to compensate for the loss of traditional communication during the re-entry phase by conducting an air-to-air reconnaissance mission.
The Phoenix capsule mission is crucial for advancing reusable, affordable, and reliable downmass capabilities. The ability to return life sciences and other types of microgravity research, rocket upper stages, military spacecraft, and manufactured resources could be the next breakthrough in space transportation. The data collected from this mission will inform the development of the Phoenix 2 capsule, expected to launch in 2026, further contributing to the advancement of re-entry technology.
