ISS Crew Rotation, SpaceX Launch Contracts, and Space Cyber Security

ISS Crew Rotation and Medical Situation

• 🧑‍🚀 NASA astronaut Mike Fincke is handing over command of Expedition 74 on the ISS to Roscosmos cosmonaut Sergey Kud-Sverchkov.
• ⚠️ Crew 11's return to Earth has been expedited due to an unexpected medical issue, with undocking scheduled for January 14th.
• 🏥 The decision to return early was made to allow for comprehensive medical evaluations on the ground, highlighting NASA's commitment to crew well-being.

US Space Systems Command Launch Contracts

• 🚀 US Space Systems Command (SSC) has awarded SpaceX $739 million in launch contracts for national security space missions.
• 🛰️ These awards include launches for the Space Development Agency (SDA) and the National Reconnaissance Office (NRO), supporting missile warning and tracking capabilities.
• 📅 Launches for SDA missions are projected to begin in late fiscal year 2026, with NRO missions starting in early fiscal year 2027.

SpaceX Twilight Ride Share Mission

• 🌌 SpaceX successfully launched a Falcon 9 carrying NASA's Pandora planet-observing satellite and 39 other payloads.
• 🛰️ The mission included NASA-sponsored CubeSats like SPARKS and Black Cat, as well as payloads for Spire Global and HawkEye 360.

Indian Rocket Launch Anomaly

• 💥 India's Polar Satellite Launch Vehicle (PSLV) experienced an anomaly after takeoff, failing to deliver 16 payloads into orbit.
• 📉 This marks the second failure for the PSLV in eight months, impacting the Indian Space Research Organization's (ISRO) reputation for reliability.

Eutelsat OneWeb Satellite Contract

• 🛰️ Eutelsat has contracted Airbus Defense and Space to build an additional 340 OneWeb low Earth orbit satellites.
• 📈 This brings the total number of OneWeb satellites ordered from Airbus to 440, with deliveries starting in late 2026.

Space Cyber Security Focus

• 💻 The discussion highlights the increasing importance of cyber security in space systems, with a shift in focus from ground systems to space vehicles since 2019.
• 🛰️ Space systems are critical to 55 national critical functions, making them a target for adversaries seeking to inflict widespread disruption.
• ⚠️ Threats include RF-based attacks and supply chain compromises, which are particularly challenging to address once assets are in orbit.
