# Europe's Asteroid prang probe plan calls for cubesats

The European Space Agency (ESA) has decided to include cubesats in the design of its planned Asteroid Impact Mission (AIM). Cubesats are 10cm3 modules that mostly use commercial-off-the-shelf electronics. Most don't include any propulsion, instead relying on being released into space to do their jobs. That approach makes the …

1. #### ... 10cm^3 modules ...

10cc ? Rubber Bullets ?

Perhaps you mean 10 x 10 x 10 cm = 100 cm^3

1. #### Re: ... 10cm^3 modules ...

Perhaps you mean 10cm x 10cm x 10 cm = 1000 cm^3?

1 dm^3 or 1 litre would also be acceptable answers.

1. #### Re: ... 10cm^3 modules ...

What's that in double-decker buses?

2. #### Re: ... 10cm^3 modules ...

"1 dm^3 or 1 litre would also be acceptable answers."

Not round here it wouldn't. IT would need to be 1.7362 Bulgarian airbags.

Regular or Olympic sized?

1. #### Re: IT would need to be 1.7362 Bulgarian airbags.

Olympic sized Bulgarian airbags are smaller than standard sized ones, IMHO after watching the 2012 gymnastics.

2. #### Re: ... 10cm^3 modules ...

I suspect it means 'ten centimetres cubed' rather than 'ten cubic centimetres'c

2. #### 1,000 ccm

in Reg units:

Walnut: 11.9366

Chicken's egg: 5.4567

Grapefruit: 1.9099

Bulgarian airbag (C-cup Posh Spice): 1.7362

Bulgarian funbag (DD-cup Jordan): 0.5841

Football: 0.1725

Olympic-sized swimming pool: rounded to 0

3. #### In 1950ies / 1960ies SF stories

they would send a big spaceship with a large crew equipped with shovels and pickaxes...

Don't really know where I'm going with this, must be the flu medication. Anyway, the cubes are a good idea.

4. #### Didymos?

Is this pair of asteroids to be found in orbit around Knotty Ash?

Mine's the one with the ticking stick in the pocket...

5. #### So...

does one cube have little pins in it that stick out? And another one might play The Birdy Song repeatedly, or spew fire, or create localised rain storms? So long as they last longer than 47 minutes anyway.

Yet more rubbish in orbit

Well they aren't rubbish (while they're still working), but an increasing number of small satellites certainly isn't going to make things any easier to manage up there.

Cubesats so far launched are mostly in low earth orbit; they'll re-enter and burn up between 5 and 10 years after launch.

7. Technically they won't be in Earth orbit.

8. #### "a pair of asteroids called Didymos"

Aw diddums, look! We've got you some shiny new blocks to play with!

9. #### "...and landing a CubeSat for seismic monitoring.”

They are going to fit propellant, attitude control, landing gear, seismic monitor, transmitter, and battery in a 10cm cube. I'm impressed.

Most don't include any propulsion < read this bit (called "the story") before responding

1. #### Re: "...and landing a CubeSat for seismic monitoring.”

Most don't = some do. And if it is going to manoeuvre it's way onto the surface of an asteroid, then this one does. So leave out the snarky RTFA comments please.

I think "landing" in this context may be a euphemism for "impacting".
