D-Orbit, a global leader in space logistics and orbital transportation, launched Above the Summer Sky, the 23rd commercial mission of its orbital transfer vehicle (OTV), ION Satellite Carrier (ION), aboard SpaceX’s Transporter-17 mission. The OTV was launched from Space Launch Complex 4E (SLC-4E) at Vandenberg Space Force Base in California at 00:12 PDT (07:12 UTC). Following liftoff, ION SCV Joyful Julia was released into a Sun-synchronous Orbit at an altitude of approximately 590 km.

The OTV carries a diverse mission manifest, combining satellites destined for deployment into their operational orbits with hosted payloads undergoing in-orbit testing and demonstration. Upon reaching orbit, ION will join D-Orbit's growing fleet of ION vehicles already operating in space, further expanding the network supporting D-Orbit's Space Cloud services and in-orbit computing capabilities. 

"This mission adds a new node to a fleet that is already at work in orbit, reinforcing the infrastructure we are building mission after mission. Our platform is mature enough to serve an ever-increasing sophisticated range of mission needs: from securing data integrity in space, to validating 6G communication technologies, to expanding satellite constellations for maritime safety," said Matteo Andreas Lorenzoni, Director of D-Orbit Orbital Access Business Unit. “ION was designed to serve exactly this kind of diversity, and we are seeing that value compound with every mission.”

ION Satellite Carrier is a versatile space vehicle capable of transporting and releasing satellites into distinct orbital slots. It can also accommodate third-party payloads, including innovative technologies, research experiments, and instruments requiring in-orbit testing. Additionally, ION can support edge computing and space cloud services, providing satellite operators with advanced storage and computational capabilities in orbit. D-Orbit's mission control team is now conducting the Launch and Early Orbit Phase (LEOP), setting the stage for the upcoming operational phase. ION carries:

• Cesário, Florbela, Torga (Lusospace) - The satellites, named after Portuguese writers, will join in the skies PoSAT-2, Camões, Agustina, Saramago and Pessoa, to increase the Lusíada constellation formation, designed to advance maritime communications through VDES technology, delivering higher bandwidth, enhanced data integrity, and improved safety over current AIS-based systems. After T17 Launch LusoSpace will have 7 out of the 12 satellites of Lusíada constellation in operation.
• Stardome SNS (Stardome) - The Stardome Notary Source (SNS) is a hardware module designed to provide satellites with a secure digital identity and to certify the authenticity and integrity of data generated in orbit. By digitally signing data at the source, the system enables users to verify where and when information was produced, helping establish trusted and tamper-evident space data.
• QSAT1 (Qualcomm) - QSAT1 is a research platform designed to test and validate advanced satellite communication technologies directly in orbit. Its mission is to evaluate key functionalities needed for the future evolution of 5G-Advanced NTN systems to 6G that integrate terrestrial and satellite networks, including signal transmission, system integration, and performance under real space conditions. The payload will collect data to support the development of next-generation communication architectures.

Expanding the mission manifest, on two ports of the Transporter-17 mission, D-Orbit is also launching an undisclosed client along with:

• SENTINEL-1 by Ethereal Space. SENTINEL-1 represents the Company's first flight of its operational platform for the scaling of its commercial space weather and environmental data constellation. Building on prior flight heritage, the mission introduces several platform enhancements, including a newly designed deployable solar array to increase power generation across orbit. Data from this flight will be used to validate the operational architecture and reduce risk ahead of the next series of launches beginning in October.
• SUCHAI-4 a 3U CubeSat developed by the Space and Planetary Exploration Laboratory (SPEL) at the University of Chile. Weighing just 5 kg, the nanosatellite will conduct scientific experiments in orbit, including the observation of biological samples in the space environment and the testing of advanced technologies such as optical laser communications and a fine-pointing control system. The mission involves Chilean universities and international partners from the United States and the Netherlands and is primarily funded by Chile's National Research and Development Agency (ANID).

With this launch, D-Orbit has now deployed almost 230 payloads in orbit since the inaugural ION mission in 2020, establishing itself as a trusted partner for satellite deployment, in-orbit testing and space logistics services.
