Should companions orbiting a brown dwarf be considered a moon or a planet?
They possibly detected a planetary-mass companion orbiting a brown dwarf. Here's the abstract of the paper in Nature. It's a 0.9 Jupiter mass companion orbiting a brown dwarf with 29 Jupiter masses. There's no scientific consensus if this should be considered a planet or moon. I'm curious what you guys lean towards.

Curated MIT 16.00x (Astronautics & Human Spaceflight) Lecture Playlist for Anyone Learning Aerospace
Hey everyone,
I’m fairly new to aerospace engineering and currently working my way through foundational concepts. While diving into open resources, I came across MIT’s 16.00x: Introduction to Aerospace Engineering (Astronautics and Human Spaceflight), taught by former NASA astronaut Dr. Jeffrey Hoffman.
The full course structure is available on MIT OpenCourseWare, but navigating through the website modules just to watch the video lectures sequentially felt a bit clunky.
To make it easier for continuous watching, I organized all the core video lectures into a single sequential YouTube playlist.
I wanted to share this here in case anyone else is starting out, looking for a refresher, or wants an accessible stream of the lectures without clicking through nested course pages.
Here is the playlist link: `https://youtube.com/playlist?list=PLQ5yLmZZOIoI&si=dOGwMTgWExVTH1Q6`
The course covers:
Rocket science fundamentals (thrust, specific impulse, multi-stage rockets)
Orbital mechanics & delta-v budgets
Life support systems (ECLSS) and microgravity physiology
Spacesuit design and EVA mechanics
Hope this is helpful to someone else on a similar learning path!

Obama Scrubs NASA's Manned Moon Missions
Although NASA will get a budget increase for 2011, plans to return humans to the moon by 2020 would be officially scrapped, because the program is "over budget, behind schedule, and lacking in innovation," according to the White House.
