- I just released FIRST ORBIT! It's a spaceflight sim I made to help teach astrodynamics in an interactive and visual way. It features full n-body mechanics, allowing for Lagrange points, low energy transfers, and other cool trajectories. https://youtu.be/fcG870WP6PM?si=s_7JIoBpgdS7BFNq 3 comments space
- JAXA, The Japanese Space Agency, has launched a tiny 14kg spacecraft from the Orion spacecraft in lunar orbit. Using 1.5kg of water steam as propellant, it will travel to the Earth-Moon Lagrange point (EML2) to make tests on its suitability for a human crewed deep spaceport. https://interestingengineering.com/science/japans-spacecraft-using-steam 2 comments futurology

- NASA's next steps into space may be Lagrange points - where the gravitational acceleration from the Earth and the sun are exactly equal. Spacecraft can coast along the gravitational contours of space between these 'lowlands'. May become staging areas for further trips and telescopes. http://www.newscientist.com/article/dn17713-why-future-astronauts-may-be-sent-to-gravity-holes.html?dcmp=otc-rss&nsref=online-news 12 comments science
