Could two satellites in the same orbit, but phased differently, be tethered in a sustainable manner?

Was reading this, and I immediately saw the problem with the angular momenta not lining up. Unfortunately, my mind likes to keep turning scenarios over and asking what would happen if ...

Space elevator idea

Just wondering if it would be possible to make a space tether/elevator out of looped rubber bands like that of a loom bands like the common loom band? Each time a new band is added for length, the ...

Why are electrodynamic tethers not used to propel payloads beyond LEO?

Bringing spacecraft to higher orbits than LEO is quite expensive and as rocket reusability gains traction, it will probably get even more expensive when compared to a standard LEO deployment since the ...

How do you find ZRVTOs between tethers from coplanar, tidelocked bodies?

In 1984 JPL engineer Paul Penzo described a ZRVTO (Zero Relative Velocity Transfer Orbit) between an elevator anchored on Deimos and an elevator anchored on Phobos. Here is a Penzo’s illustration: ...

If there was a non-rotating skyhook in Earth orbit, what would re-entry be like after dropping from its foot?

I have been looking at a space station that orbits Earth at an altitude of 3500 km above the equator, and has tethers that extend from it downwards to 250 km above the surface, and outwards to 6500 km ...

Space elevator orbit below GSO but slow enough to be caught by an airplane

I've read a space elevator at GSO 35,800 km (actually above GSO to create the needed counterweight) is not feasible due to lack of current available strength of materials. Also that a tether at low ...

How/from where did the the two TiPS components get the names Ralph and Norton?

From Gunter's Space Page: The TiPS (Tethers in Space Physics Satellite) satellite is a tether physics experiment consisting of two end masses connected by a 4 km non-conducting tether. The ...

How to calculate drop due to ship docking at orbital tether

I am exploring some of the properties of a vertical orbiting tether (or non-rotating skyhook). This particular tether has a quite large mass at the location with a circular orbital velocity, with the ...

How well could the tether tension method of attitude control actually ultimately work for a cubesat system?

The phys.org new item Image: Small satellite deployed from the Space Station shows the cubesat craft Space Tethered Autonomous Robotic Satellite (STARS-C) being deployed from the ISS. A satellite ...

What would be the challenges of a non-rotating tether orbiting the Moon?

There are examinations of lunar tethers going through the EML1 point, and rotating tethers in various orbits of the Moon. But I haven't seen an examination of a tether in orbit that doesn't rotate. ...

Have there been any designs for multi staged space tethers?

My understanding of the idea of a space tether is that currently you wouldn't be able to build one because even just having it support it's own weight we don't have strong enough material, and with ...

Could air be collected by a tether system from orbit?

We have all sorts of spacecraft orbiting just above a huge reservoir of nitrogen and oxygen. Isn't there some way one could be designed to reach down and pump that air into canisters, and store them ...
