Why couldn't we land a capsule which could be ejected from a comet with thrusters within the capsule. We would simply use the mass of the comet to achieve speeds unheard of in interstellar travel with or without thrusters and non-renewable fuel sources this could in theory launch so many probes into space into orbits which are well established and well-known?

I just got back from the most infuriating, and fulfilling trip of my life. I traveled to a remote location, far from the city lights, to witness the breathtaking beauty of the night sky. I hiked for hours, flew to a nearby airport, and drove for miles on treacherous roads to reach this supposed paradise.

And when I finally arrived, I was awestruck by the sheer vastness of the stars. The sky was a colour I never thought it would be, and the constellations twinkled like diamonds. So many stars, in colours I never knew they came in. Surreal experience. But my wonder was short-lived.

Every. Single. Time. I looked up at the sky, a freaking satellite would streak across my line of sight. It was like the universe was mocking me.

At first, it was novel. I'd never seen so many satellites in my life. Onky thing Ive seen is the ISS. But soon, it became an annoying, infuriating, and downright depressing experience. I felt like I was being robbed of the very experience I had traveled so far to witness.

What's the point of preserving these pristine natural locations if we're just going to fill the skies with our trash?

I'm not a scientist, but I know that this is not sustainable. We're not just talking about the visual pollution; we're talking about the very real threat that these satellites pose to our planet.

So, to all the space agencies and private companies out there, I have one message: get your act together. Start thinking about the consequences of your actions. We're not just talking about the night sky; we're talking about our future.

First off, Everyone keeps forgetting about all of the natural extinction level events our astronomers see.

Start with supernovae that would destroy everything for a hundred light years. Combined with their magnetic pole shotguns that reach much further.

Secondly, Everyone thinks that life started on our Earth rather recently.

Why?

Something was here before the the Moon was formed. Our surface was reduced to magma with that impact. Not even a stainless steel sink would survive. No evidence of anything.

Thirdly, Our planet is in a shooting gallery. Not just from local asteroids and comets. Even with a superb detection system, Extra-solar transients do come through our system. They come through at very high speeds. The path is not always on the orbital plane.

My conclusion: for the Human Race to survive, we need to spread off this planet and away from this solar system as soon as possible.

Elon Musk wants to colonize Mars. I think for the wrong reasons. But it is a step in the right direction

Hello I am relative new to mma. Have only boxed a little and is looking for a mma only gym. Anyone who knows a good place?

I’ve seen various suggestions of sending probes far away to outer space to use the gravitational field of the Sun as a giant lense. However, reaching that point would take decades, and technology required for it has not been produced yet.

This leads me to my question: could we use the second largest object in our Solar system, namely Jupiter, in a similar way? Now, I instantly recognize the huge difference in mass between the Sun and Jupiter, meaning the lense couldn’t be expected to be as effective. None the less, wouldn’t this be a possible way to pilot the technology before sending probes further away?

Lastly, some follow-up questions if this idea is possible:

1. How significant would the advancement gained from Jupiter’s gravitational lense be? (Aka could it be expected to exceed our current telescope capabilities).

2. How far would we actually have to send a probe to reach this focal line? (Aka can we expect it to be significantly nearer than the Sun’s focal line).

I want to try some space simulator or play any space exploration game. Any recommendations?? The only issue is i don’t have a windows system which might shrink the available options. Please let me know!!

My favorite would be that we’re early to the party. Cool Worlds Lab has a great video that explains how it’s not that crazy of a theory.

Hi r/space! We’re John Moores, Jesse Rogerson, and Michelle Parsons, the co-authors and illustrator of “Daydreaming in the Solar System,” a journey through the solar system that merges imagination with hard science. John has been a member of the science and operations teams of several space missions, including the Curiosity Rover Mission. Jesse is a science communicator who’s worked in some of Canada's premier museums and science centers, including the Canada Aviation and Space Museum.

Ask us anything about the ethics of space exploration, the possibilities for life in our solar system, and more. We’ll be here Tuesday 12/3 9 am until 11 am ET to answer your questions! Our AMA proof: Jesse, John and Michelle.

I just need to tell someone this. Happened about 10 minutes ago, whole thing lasted around a second but it was absolutely amazing. It really made my night, I never would've thought I would see a shooting star in real life and yet here we are! That's all, thanks for reading. :)

4 years ago, I claimed Chandrayaan2 rover might be still intact on Moon's surface from LRO images and now ISRO has published crash images before and after landing

Before landing: Sep6th 12:46 UTC
After landing: Sep6th 22:41 UTC

The same objects can be also see in the LRO images taken after the crash landing (Skeleton Lander and intact Rover)

Next year, I’m embarking on a mission to dedicate a month to exploring each planet in our solar system, starting with Mercury. I’d love any recommendations for documentaries about Mercury or additional reading materials.
