We will colonize the galaxy in shoebox sized space ships. Looks like we'll have to invest in human shrinking technology.

Will we also have giant space hamsters?

Subby wishes he had 50 micro newtons of thrust

No, just the miniature versions.

We were lost, none of us knew where we were. Then Harry starts 'feeling around on all the trees' and he says... "I got it we on Pluto", I say, 'Harry how can ya tell?", and he says, "from the bark, you dummies. Ha-ha! From the bark!"

I'm hoping for dyson spheres.

Stage Trees? Larry Niven already covered that.

They're going to make like trees, and leave.

The article started off really promising. To my non-expert self, it initially sounded like they might have created a thruster that needed only energy, no reaction mass. Such an engine is the key to truly conquering space. Alas, about 2/3 through, they let on that these thrusters require liquid reaction mass.

Subby...we have that propulsion, used in space for more than a decade.

Miniature satellites, however, are a more novel and relatively unexplored realm of thought.

CubeSats have been operational for a while now. If your payload can fit in a 10 x 10 x 10 cm cube and weighs less than 1.33 kg (roughly 4 inches and 3 pounds), it can be launched into low Earth orbit and deployed using a standardized system. The CubeSat(s) and in-orbit launcher can be piggybacked onto conventional satellite payloads for less than $100,000.

These new ion microthrusters can give CubeSats or other nanosatellites the same maneuverability and aiming capabilities as their full-sized counterparts

Still all we can do with the cubes is hang them up there for a bit.
I was referring to the article's purposes. What can be done with the cubes that are mobile.

IIRC, the ion propulsion is a sloooooooow acceleration, so in this case smaller doesn't necessarily mean more agile. He's talking about spins and such in the article as if you're up there with a tiny jet, zipping around everything that's in the way and such. Not sure if that's possible without some kind of conventional propulsion/thrusters.

It's the efficiency of the thing that is impressive.
Since the game of space travel is all about weight,Carrying a few ounces of fuel is far superior to carrying hundreds of pounds.

The only way to have an engine that didnt need fuel would be to build a photon rocket. Consider how effective pushing yourself around with a lightbulb would be. The energy input required to get practical thrust would be on the order of exploding hydrogen bombs, in which case you might as well just use H-bombs.

Well, or an Alcubierre drive, but that has its own problems.

If you want to have practical interstellar travel on a time scale compatible with a contiguous human civilization, you need new physics. Period.

I thought headline said "space prostitution".
This is considerably less interesting.

There should be a "NOT WARP DRIVE" tag for every "space propulsion breakthrough" article that is actually just an incremental step like this one...
