Discussion Overview

The discussion centers around potential solutions for the problem of space debris, as highlighted by a reward offered by NASA for innovative ideas. Participants explore various concepts, including the feasibility of using small maintenance robots and small rockets, as well as alternative ideas like giant space nets.

Discussion Character

  • Exploratory
  • Debate/contested
  • Conceptual clarification

Main Points Raised

  • One participant suggests using small maintenance robots to manage space debris, proposing that they could be controlled remotely and eventually automated, though they express concerns about budget and international cooperation.
  • Another idea involves launching small rockets designed to impact debris and either push it out of orbit or into the atmosphere, but the participant acknowledges a lack of technical knowledge regarding feasibility.
  • Some participants express skepticism about the realism of the proposed ideas, questioning their practicality and potential costs.
  • A later reply raises concerns that using small rockets could exacerbate the space debris problem by adding more objects to orbit.
  • Another participant questions how maintenance robots would locate and manage debris, highlighting the challenges of automated rendezvous with non-cooperative targets.
  • There is a suggestion for using giant space nets, but further details on their design and propulsion are requested.

Areas of Agreement / Disagreement

Participants express a mix of ideas and skepticism, with no consensus on the proposed solutions. Some participants challenge the feasibility of the ideas presented, while others continue to explore and refine their concepts.

Contextual Notes

Participants assume that NASA may have tracking capabilities for debris, but this remains unverified. The discussion includes unresolved questions about the energy requirements for proposed solutions and the potential for creating additional space debris.

Hello, i saw a reward posted for the solution of the problem of space trash by Nasa.

There are thousands of small objects in space that are discarded rocket parts, pieces of satelittes and general junk up there.
It is orbiting the Earth at high speeds and Nasa can't solve this problem (yet)

i read that they have had some ideas that were either too much of a long shot or just not doable in praksis such as heating the object with lasers from the ground til they evaporate etc.

I have a few ideas that may or may not be stupid, i do not know the answer because i don't know what technologies Nasa has available.

These ideas may be garbage if they don't have the tech, or if it would be too costly, so please come with ideas of your own.
After all... if we solve this it would be awsome for the forum, and whoevers idea they think is worth the effort.

Idea 1: Small maintenance robots. If we could build small robots (size of a football) and remote control them from Earth we could launch maintenance satelittes that control their assigned area for scrap objects. They would run on electricity and a propellant of choice and be able to refuel and reload at the sattelite.

this would be the permanent solution. with tech advancement it would be made automatic and run by computers. BUT.. it would probably be outside anyone space agency's budget so international co-operation would be needed.
maybe divide up the sky in sectors and divide the responsibility around.

Idea 2: Small rockets. this would be a temporary solution. i do not have the tech knowledge at all to think if this could work but it seems like a possible scenario.
Picture a piece of material that is hard and light, it has the shape and size of a card. This would be the front of the missile. Aero dynamics don't aply to space so it should have no influence over the amount of fuel needed to reach the same speeds as the object its tracking.
The missile is small, the tip hard. how many would fit on a run of the mill launch?

The thing about this scenario is that the missiles are so small that it would not require its own launch rocket. they could take as many as they could fit on the missions already going to space.


ps. i didnt know where to put this thread.
There are so many to choose from, physics, theory, math, astrology and space dynamics etc.
so please don't delete if i posted it in the wrong forum.

Errrrrrr...I'll let someone else comment, or delete this thread. You're ideas don't sound very realistic to me, sorry. :frown:
 
Could you be a little more specific?.
what isn't realistic?

is it too expensive or not the required tech?
 
HA HA HA! There's a blast from the past. Thanks Janus!

How in the world do you pronouce "Cyb"? Who would name their daughter Cyb?

It's short for Cybil, as in Shepard... pronounced 'sib'.
 
i think the small rocket idea would just make more space garbage since not all would hit, and youd be putting more stuff up there.

how bout giant space nets?
 
the missiles arent explosive, they are more like "bilijard balls" their purpose is to impact with the trash and either push it out into space or into the atmosphere. both are good.

Space nets: how big are we talking?, what propells them, how do they work etc.

Regarding the robots: How do the they get rid of trash? How do they even know where it is? Automated rendezvous with even a cooperative target remains a very challenging problem. The trash is a very non-cooperative target.

Regarding the rockets: Do you realize how much energy must be imparted to "push an object into space" or into the atmosphere? How do you keep your rockets from adding to the space trash problem?

hmmm, there is much i haven't thought off...
i went from the assumtion that NASA had a map over their locations and velocities.
if so then the calculations should be possible.
