Booster 19 preparing to begin prelaunch testing
SpaceX's post captures Super Heavy Booster 19's rollout to Massey's test site for cryoproof testing via a 43-second sunset time-lapse video, showcasing the 70-meter structure amid Starbase infrastructure.
As the second Block 3 booster after Booster 18's November 2025 anomaly during static fire, B19 incorporates design tweaks for enhanced engine reliability and rapid reuse.
Targeted for Starship Flight 12 in early March 2026, this milestone aligns with FAA approvals for up to 44 annual launches, advancing reusable architecture for Mars missions.

SpaceX has developed a novel Space Situational Awareness (SSA) system, called Stargaze →
To maximize safety for all satellites in space, @SpaceX will be making Stargaze conjunction data available to all operators, free of charge. By providing this ephemeris sharing and conjunction screening service free of charge, we hope to motivate operators to take similar steps towards ephemeris sharing and safe flight.
SpaceX's post introduces Stargaze, a Space Situational Awareness system leveraging 30,000 Starlink star trackers to detect nearby objects and predict orbits, generating collision alerts in minutes versus hours.
The accompanying animation visualizes Stargaze's process: from object detection via stellar observations to autonomous trajectory updates and avoidance maneuvers, as proven in a 2025 real-world deconfliction that eliminated a 60-meter risk.
By sharing free conjunction data to all operators, Stargaze promotes industry-wide ephemeris reciprocity, addressing escalating orbital congestion where collision risks have surged amid a 26% higher chance of debris intersecting busy airspace in 2026.

SpaceX's post highlights Falcon 9's role in the GPS III-9 launch, achieving a 41-day turnaround from payload integration to orbit, marking the third rapid mission for the US Space Force and underscoring reusable rocket efficiency.
The mission deployed the ninth GPS III satellite (SV09), an advanced navigation spacecraft originally slated for ULA's Vulcan but switched to Falcon 9, enhancing global positioning accuracy and anti-jamming capabilities for military and civilian users.
This rapid deployment capability strengthens national security by enabling quick satellite replenishment, reducing vulnerability to threats and contrasting with longer timelines of traditional launch providers.
Mission Overview: GPS III-9, the ninth satellite in Lockheed Martin's advanced GPS III series for the US Space Force, boosts global positioning accuracy to 1-3 meters while adding anti-jamming and secure military signals, launched via Falcon 9 from Cape Canaveral on January 28, 2026, after a weather delay.
Rapid Turnaround Milestone: This mission achieved a record 41-day integration-to-orbit timeline for a National Security Space Launch, surpassing prior benchmarks and enabling faster deployment of critical defense assets.
SpaceX's NSSL Role: As the third "rapidly accelerated" US Space Force mission on Falcon 9, it underscores SpaceX's dominance in the $13.7 billion NSSL Phase 3 contract, with over 300 successful launches proving reliability for sensitive payloads.

The major breakthrough SpaceX is targeting this year (2026) is achieving full reusability with Starship—meaning both the Super Heavy booster and the Starship upper stage (ship) are caught, refurbished, and reflown rapidly without being discarded.
No rocket has ever accomplished true full reusability for an orbital system, and it's a game-changer because it directly slashes the cost of getting to space. SpaceX has already demonstrated partial reusability with Falcon 9, successfully landing and reusing the first-stage booster more than 500 times, but the upper stage is still thrown away and destroyed on reentry (at a cost comparable to a small-to-medium jet aircraft).
With Starship—the largest flying machine ever built—Elon Musk has expressed strong confidence that full reusability will be proven in 2026. This could reduce launch costs by roughly 100 times, making it dramatically cheaper to deploy large satellites, build massive constellations, refuel in orbit, send cargo (and eventually humans) to the Moon and Mars, and enable high-volume space operations. It's the key technical step toward making humanity multiplanetary.
The post shares a video clip of Elon Musk explaining SpaceX's 2026 goal for full Starship reusability, building on over 500 Falcon 9 booster landings while discarding upper stages, to slash space access costs by 100 times.
As of January 2026, SpaceX has achieved initial Super Heavy booster reuse in late 2025, marking progress toward full-stack reusability, though upper-stage recovery remains a key challenge per recent aerospace reports.
Achieving this could enable affordable large satellite deployments and Mars missions, aligning with Musk's vision for multi-planetary life, as evidenced by planned uncrewed Starship flights to Mars in 2026.
