Space debris used as fuel to propel "autophagous" rockets

Ecological and spatial innovation this morning.

We may have found a solution to limit the space debris that accumulates, both in the ocean and in space.

We're going to use them as fuel to propel the rocket.

These are called "autophagous" rockets.

Rockets that will burn their own propellants to create thrust and be able to move forward.

It is the same principle as a candle which burns its own structure to be able to illuminate.

The advantage is that in the end you don't leave any waste behind.

A rocket is made up of several stages, filled with fuel, and which break off as they empty.

What are they becoming?

They fall back into the ocean where they accumulate in orbit.

And with the proliferation of satellite launches, this is starting to cause problems.

This is why there are now reusable rockets, the launcher of which returns to earth.

Yes, that's what the Americans from Space X are offering. But the Scots at Glasgow University think they've found an even cheaper alternative with these autophagous rockets.

Instead of today's very complex engines, a simple tube filled with solid fuel would be used.

It would then be enough to turn it on to make the rocket take off.

The tube will then dissolve, from bottom to top, as it ascends into orbit.

It is schematized but they have already shown that it is possible with a prototype in reduced size.

A new test is planned next year at full size.

The Americans in Space X could very soon have European competition;

less expensive and which leaves no more debris.
