well we were developing a chamber design for the battery that had never been done before and were funded by nasa to do so, so their existence wouldnt have been relevant to our work whether I knew of them or not

Its hard because of lack of light

We can’t find it with the Hubble or James Webb lol? Although to my understanding the James Webb is infrared or something

Because to find it you need money, probes and space.
We barely have managed to send robots on mars. Maybe one day when people build telescopes that orbit pluto, we might know.

Whatcha gonna breathe and eat and no more fish on friday. What do ya do for energy when you go interstellar. We could send robots except they aren't smart enough.

Even if we were to somehow detect a thousand more possible targets within that radius, I'm afraid we make no appreciable dent in the odds of finding an object on a viable trajectory. You are looking at a sphere with a surface area of 3142 square light years. So let's say the diameter of these targets is about 120 AU (a rough number for the radius of our heliosphere). That gives us an area of 0.000000215 square light years. That's a pretty tiny bullseye.
Although your comment about gravity assist implies that you are no longer interested in using the existing speed of the asteroid as you would need to manoeuvre it to slingshot around a gravity well, likely spending orders of magnitude more energy to do so than you have 'saved' by using an already moving object. At that point it would be be cheaper and easier to just build your space craft.

Did all that and had no idea of the current leader in the 'space.' Nice college indeed.

Reply to comment by Alvsvar in How much space does it require to accommodate 1 hydrogen atom? by Alvsvar
I was downvoted a bit, but the top answers are acting like atoms just "end" at some point; I mean, the answer they give, I'm guessing, would be just about right - but my point is that it is a sort of a "functional" definition... they are, in some sense, processes - atoms. Or events.
u/DudeWithAnAxeToGrind is saying good things; it's about when you decide it no longer looks like a "quark-gluon plasma" to you, and when it looks more like atoms. we don't even understand how water works, if you start looking at it close, like that

dang, my research in college was designing a system for lunar rover batteries to allow them to survive the lunar night and now my job is designing a lunar lander, ima look into these guys.

Reply to Random thought I had in science class by VanCro999
Good thought. Many scientists have already thought about it. Its called terraforming.
Mars has many problems thst need to be solved for humans to live there.
-
Atmosphere. Somehow, you need oxygen, and filler gas nitrogen and some carbon there. You can get these vis comets in theory but we dont even have a way to control comets or steer them into mars.
-
Soil. Mars has no soil. The ground in mars is self sterilizing. Its toxic to bacteria and plants. We would need to remove or change the surface. Also bring soil from earth. The dust is also sharp. You dont want to breathe in that or you are dead.
-
Magnetosphere. No protection from cosmic rays. In theory a thick atmosphere would protect people. But scientists are not 100% sure about this one.
-
Gravity. Gravity on mars is pretty bad. It might not be possible for humans to live with such low gravity.
5.Time. Terrsforming mars could take thousands if not millions of years. Its not worth it imho.
In my opinion, it would be smarter to use geo engineering or space mirrors to decrease sunlight hitting earth. This could solve our problem with the sun for billions of years and extend earths life until the red giant phase of the sun.
In the red gisnt phase, in theory, we could extend the orbit of earth away from the sun toeards jupiter.
But after that, just a bit of shade would solve the red gisnt phase of the sun aswell.
But we wouldnt have a way to prevent the death of the sun. But in theory, removing helium from the sun could extend its life.
But who knows. I enjoy discussions about space.

Well, the large amount of objects in the kuiper belt and beyond could explain the eccentric orbits of kuiper belt objects. It's pretty hard to say without sending a ship out there.

Yooo lmao thank you for calling this guy out. I keep scrolling and he just keeps going on and on no matter how many reasons ppl tell him his little fantasy makes absolutely no freakin sense. “You have land for farming on the inside of the asteroid”. like whattt 🤦🏻♂️🤣🤣🤣

Dude you just don’t give up. I have already read at least 5 really well explained reasons why this little fairytale of yours simply will not work or serves no beneficial purpose. You just keep going man like a little kid that just keeps on saying “but, but, but, what if this what if what if that”. Here’s something to remember whenever you think you have come up with the ultimate idea. There are many, many people much more intelligent than those of us writing comments on reddit. So intelligent, that anything you may think you have all figured out I can almost guarantee you has been thought of and proved as a no no. Give it a rest my friend. Cool idea but it just doesn’t make any fucking sense for us earthlings to do.

….That’s your reply? I get you’re a kid, but a smartphone and making a spaceship out of a freaking asteroid could not be further apart.

It’s funny to see how the “non-supers” have better programs than the “super powers” imo.. by better I mean their overall outlook and niche in space advancements is better..

Is this mission landing? Or are they making sure they can get into a lunar orbit?

Hi HondaVFR96,
It looks like your comment closely matches the famous quote:
"If you don't know where you're going, any road'll take you there" - George Harrison

It’s still wild how there’s only one “superpower”. Japan should be considered one because it has massive cultural influence, a pretty strong military, insane technological standings, it’s allied with basically all of nato, and more. Still waiting on Zambia to catch up in space.

The point stands. Come back in a hundred years or so, but it's like asking to hitch a ride on a log to cross the Atlantic, but the log is in China.
