Today, history was made when the first all-civilian spaceflight launched from Launch Complex 39A at the NASA Kennedy Space Center in Florida. The purpose of this flight was to raise awareness and funds for the St. Jude Children’s Research Hospital and offer inspiration to people all over the world. Operated by SpaceX and sponsored by Jared Isaacman and Shift4Payments, this flight illustrates how accessibility to space is growing by leaps and bounds.

Centauri Dreams readers will remember Billy Quarles’ name in connection with a 2019 paper on Alpha Centauri A and B, which examined not just those stars but binary systems in general in terms of obliquity — axial tilt — on potential planets as affected by the gravitational effects of their systems. The news for habitability around Centauri B wasn’t good. Whereas the Moon helps to stabilize Earth’s axial tilt, the opposite occurs on a simulated Centauri B planet. And without a large moon, gravitational forcing from the secondary star still causes extreme obliquity variations.
