What’s better than a rare Super Delta formation featuring the Thunderbirds and the @USNavy Blue Angels over Washington, D.C.?
Watching it from four different views for #UFCWhiteHouse as part of #Freedom250. 🇺🇸
This is what peak 2008 looked like.
18 years ago, these two brothers accidentally created an internet classic, and it became one of the most unforgettable time capsules of the late-2000s electro era.
I took 1.7 million photos over 6 days to catch this photo of a commercial jet in front of the sun.
The moment it happened, TWO floating prominences were visible, making this not just my best aircraft transit photo, but one of the luckiest of my career! Videos of the transit 👇
SpaceX has just released a massive new list of changes in Starship V3, which is now scheduled to launch on May 19th:
Super Heavy V3 Changes
Grid Fin Redesign:
• Reduced from 4 fins to 3
• Each fin is now: 50% larger, stronger, repositioned for better catching/lifting
• Lowered on booster to reduce heat exposure during hot staging
• Fin hardware moved inside fuel tank for protection
Integrated Hot Stage:
• Removes the old disposable interstage shield
• Booster dome now directly exposed to upper-stage engine ignition
• Tank pressure + steel shielding protect structure
• Interstage actuators retract after separation for protection
New Fuel Transfer System:
• Massive redesign of fuel transfer tube
• Roughly the size of a Falcon 9 first stage
• Allows: simultaneous startup of all 33 Raptors, faster and more reliable flip maneuvers
Engine Bay / Thermal Protection Changes:
• Engine shrouds removed entirely
• New shielding added between engines
• Propulsion + avionics more tightly integrated
• CO₂ fire suppression system removed
• Simpler and lighter aft section
Propellant Loading Improvements:
• Moved from 1 quick disconnect to 2 separate systems
• Adds redundancy
• Reduces complexity of pad interfaces
Starship V3 Changes
Completely Redesigned Propulsion System:
• Clean-sheet redesign
• Supports: new Raptor startup method, larger propellant volume and improved reaction control system
• Reduces trapped/leaked propellant risk
Aft Section Simplification:
• Fluid + electrical systems rerouted
• Engine shrouds deleted
• Large aft cavity removed
Flap Actuation Upgrade:
• Changed from: 2 actuators per flap to 1 actuator with 3 motors
• Improves:, redundancy, mass efficiency, cost
Faster Starlink Deployment:
• Upgraded PEZ dispenser
• Faster satellite deployment speeds
Long-Duration Spaceflight Capability:
• New systems added for: long orbital coasts, orbital refueling, cryogenic fluid management, vacuum, insulated header systems and high-voltage cryogenic recirculation
Ship-to-Ship Docking + Refueling:
• Added 4 docking drogues
• Added propellant transfer connections
• Directly supports in-space refueling architecture
Avionics Upgrades
Massive Electrical System Upgrade:
• ~60 custom avionics units
• Batteries/inverters/high-voltage systems integrated together
• ~9 MW peak power capability
Better Navigation + Redundancy:
• New multi-sensor navigation system
• Designed for precision autonomous flight
Propellant Monitoring in Space:
• New RF sensors measure propellant levels in microgravity
• Important for orbital refueling missions
Camera + Connectivity Upgrades:
• ~50 onboard camera views
• 480 Mbps Starlink connectivity onboard
• Low-latency redundant communications
Raptor 3 Engine Changes
Higher Thrust:
• Sea-level Raptors:
• Increased from:
230 tf → 250 tf
507k lbf → 551k lbf
Vacuum Raptors:
Increased from:
258 tf → 275 tf
568k lbf → 606k lbf
Lower Mass:
• Sea-level engine mass reduced: 1630 kg → 1525 kg
Simpler Design:
• Sensors/controllers integrated into engine body
• Removes need for engine shrouds
• New ignition system for all variants
• Huge Vehicle-Level Weight Savings
• ~1 ton saved per engine across vehicle systems
Launch Pad 2 Upgrades (Starbase)
Faster Propellant Loading:
• Larger propellant farm
• More pumps
• Faster fueling operations
Chopstick Improvements:
• Shorter arms for faster movement
• Switched from hydraulic → electromechanical actuators
• Better reliability + redundancy
Stronger Quick Disconnect Arm:
• Reinforced and redesigned
• Swings farther away during launch
Launch Mount Redesign:
• Better load handling
• Improved launch protection
• Improved throwback reliability
New Flame Diverter System:
• Bidirectional flame diverter
• Designed to eliminate ablation/refurbishment after launch
Hardened Propellant Systems:
• Methane and oxygen systems separated
• Valves/filters moved into protected bunker
• Improves safety and reliability
SpaceX: "Together, these new elements are designed to enable a step-change in Starship capabilities and aim to unlock the vehicle’s core functions, including full and rapid reuse, in-space propellant transfer, deployment of Starlink satellites and orbital data centers, and the ability to send people and cargo to the Moon and Mars."
This is going to be an epic flight! 🚀

@NASAWebb and @ChandraXray joined forces to deliver this view of the Cat's Paw Nebula. Different wavelengths combine to reveal young stars at the center of these dusty clouds.
In 1951, scientist Adelbert Ames created the mind‑bending Ames Window.
This optical illusion features a rotating trapezoidal window that appears to oscillate back and forth instead of spinning continuously.
It’s so effective that, even when you understand how it works, you still can’t break the illusion.
