What if a spacecraft could cycle between Earth and... Moon orbits, performing multiple circuits of each, naturally and indefinitely, with zero propulsion? We’ve discovered a new class of stable, prograde, low-energy cycler orbits that do just that. Why these orbits matter: Ballistic → fuel-free Stable → long-term ready Near-chaotic → agile with low ΔV Low-energy → access to Earth/Moon, Lagrange points, Sun–Earth L1/L2, even heliocentric space At the AAS/AIAA Astrodynamics Specialist Conference in Boston next week, I’ll present on a new family of ballistic Earth-Moon cycler orbits that are stable, prograde, and mission agile—unlike any cyclers in the current literature. The example below is shown in both the Earth-Moon rotating frame and inertial frame. Conference Paper:show more

How moon orbits Earth 🌎..

Hey Grok if the Moon is spinning as it... orbits the Earth, then how come nobody ever sees the other side of the Moon aka the Dark side of the Moon, from any position, at anyone anywhere on Earth? Please explain it in simply terms that a 5 year old could understand.show more

1. stable orbits around black holes are very possible... and common, and lots of other things that don’t quite match up with black hole physics, but given the devil is involved i accept it 2. “geostationary orbit” is a term that only applies to a very specific orbit around Earthshow more

I just filmed this video at 6PM in South... Carolina. Sun and Moon both in the sky, and the moon isn't full. Therefore, the Earth is not shadowing the moon.show more

Earth no longer orbits around the sun... #giantess

This is how the International Space Station orbits around... the Earth.show more

The Earth doesn't orbit the Moon, and the Moon... doesn't orbit the Earth. They both orbit their common barycenter (center of mass)!show more

Earth and Moon seem so close to each other... and the big planets of the Solar System look so big. But in reality, you could fit every planet in the Solar System between the Earth and the Moon and still have room to spare. [🎞️ starwalkapp]show more

Once in a millennium moment, Earth and the Moon... crossing infornt of the Sun. Just hours before Huygens landed on Titan on Jan 14, 2005, there was a rare transit of Earth and the Moon across the Sun as seen from Saturn. It’s an event that happens only about once every 15 years, and a dead-center transit like that only twice per millennium.show more

I hope Elon and SpaceX develop a version of... the Starship which devours space junk. We have to keep those earth orbits clear of debris.show more

#asteroid 2024 YR4 and 200 clones pass through the... Earth-Moon system on Dec 22, 2032. Three of these clones hit Earth. Another hits the Moon.show more

Did you know the James Webb Space Telescope isn’t... orbiting Earth at all? The James Webb Space Telescope operates near the Sun–Earth L2 point, about 1.5 million km from Earth. From there, the Sun, Earth, and Moon stay on the same side of the telescope, allowing its giant sunshield to block their heat and light at the same time. That keeps Webb cold and stable enough to detect extremely faint infrared signals from deep space. Because of this, Webb can peer through clouds of cosmic dust and observe galaxies whose light has traveled for more than 13 billion years. Every image it captures is not just a view across space, but a look back into the early history of the universe.show more

Space objects such as meteoroids and asteroids move across... the solar system and can collide with both Earth and the Moon. However, the Moon shows far more visible impact marks on its surface. One main reason is that Earth has a thick atmosphere that protects the planet. When many meteoroids enter Earth’s atmosphere, they burn up due to friction before they can reach the ground. This process creates the bright streaks of light we call shooting stars. The Moon, however, has almost no atmosphere, so incoming space rocks are not slowed down or burned up. They travel directly to the lunar surface and strike it at very high speed. Each collision creates an impact crater, throwing dust and rocks outward from the impact point. Over billions of years, thousands of these impacts have covered the Moon with craters. Unlike Earth, the Moon also has no wind, water, or weather to erase these craters, so they remain visible for millions or even billions of years. This is why the Moon looks heavily cratered when we observe it from Earth through telescopes.show more

Flat earth theory on how Earth, Sun, and Moon move

I want to believe, but there's too much evidence... that not only tells me but shows me that they lied. I feel like low Earth orbit is as far as we can go... 1. The van Allen radiation belt. 2. The disgusted, unexciting, ashamed post moon landing conference with the three astronauts. Their body language, mannerisms, and answers scream that they're lying. 3. The lack of noise of the jet engines in the "videos." 4. How did they get the lunar rover on the spaceship? 5. No craters or dust underneath the spaceship. 6. How did the film the spaceship take off perfectly if nobody was left on the moon to operate the camera, and how was it so perfect if there was a delay? 7. The rockets and the spaceship look like a model. 8. The video of them saying that they are 130,000 miles away from Earth when all they really did was cover up the windows when they are in low earth orbit and film a small portion of Earth from low Earth orbit to simulate that they were far away, but then you find out that they're only in low Earth orbit when they uncover the windows. (Shown in the video below) 9. How we have to redesign the space suits to be able to handle the atmosphere on the moon. 10. The lack of talk and missions to the moon ever since. 11. The numerous blacked out photos from NASA. 12. How an older smartphone has way more technology than the entire spaceship back in 1969, and how we were able to even communicate with them in the spaceship as the one astronaut who passed away before the moon launch specified that they had trouble communicating between buildings and the shuttle on the ground. 13. Not one single astronaut would put their hand on the Bible and say they went to the moon. Why? 14. All the CGI and bubbles caught on NASA videos. 15. All the green screen captures and astronauts on wires in the "shuttle" and on the "ISS." There are so many bloopers and outtakes of astronauts and shuttle hatches malfunctioning, people appearing in the background of videos of the shuttle, people fading in and out, I could go on forever... How would you convince me against the evidence or prove me wrong from the arguments that I have provided?show more

Artemis II Glides Past the Moon A stunning view... from deep space shows Orion — the spacecraft of NASA’s Artemis II mission — gracefully sailing near the cratered lunar surface. The ancient, rugged Moon fills the frame as humanity’s first crewed voyage beyond low-Earth orbit in over 50 years unfolds in real time.This historic flight carried four astronauts — Reid Wiseman, Victor Glover, Christina Koch, and Jeremy Hansen — on a daring loop around the Moon, pushing farther into space than any humans since the Apollo era. The mission successfully tested Orion’s systems for future lunar landings and beyond.The breathtaking contrast between cutting-edge human technology and the timeless, airless beauty of the lunar landscape captures the spirit of exploration: bold curiosity, technical mastery, and our enduring drive to reach new frontiers. Note: This is a creative or illustrative depiction of the scene. Actual mission imagery from Artemis II shows spectacular views of both the near and far side of the Moon captured by the crew.show more
