Artemis II Stacking - Left Center Center Prepped for Lift - SLS
Engineers and technicians with NASA’s Exploration Ground Systems Program prepare to lift the left center center booster segment shown with the iconic NASA “worm” insignia for the agency’s SLS (Space Launch System) rocket to the Vehicle Assembly Building at NASA's Kennedy Space Center in Florida on Friday, Jan. 24, 2025. The booster segment is shown attached to a lifting beam ahead of integration onto the mobile launcher. The boosters will help support the remaining rocket components and the Orion spacecraft during final assembly of the Artemis II Moon rocket and provide more than 75 percent of the total SLS thrust during liftoff from NASA Kennedy’s Launch Pad 39B.

I held a talk on the Sun's magnetic field and I'd love for you to check it out!
We often take the Sun for granted—it rises, it sets, and it keeps us warm. But beneath that familiar glow is a violent, ever-changing star that influences our planet in ways most people don’t realize.
🔥 Did you know?
- A solar storm strong enough to disrupt GPS, satellites, and power grids could hit at any time.
- The Sun’s 11-year cycle affects space weather, auroras, and even radio communications.
- Observing the Sun without proper protection can permanently damage your eyes—but there are safe and incredible ways to do it.
I recently had the chance to give a talk to students about the hidden power of the Sun, and I’d love to hear your thoughts. 🌍🔭

How accurate is this account of the Mariner-1 disaster in 1962? It has lots of historical photos/footage which is cool, but how legit is the analysis of what happened and why?
