If these probes had the capability to observe the stars as the Hubble does, wouldn't we already have a functioning interferometric telescope?
Even their current imaging capabilities -- see link with Earth view from Mars -- may be sufficient, especially when combined with multiple image sources --
to provide good pictures.
Or if you can't wait

Perhaps, but it makes little sense to add Hubble-like scope capability to planetary probes, since it's an instrument they don't need for planetary research. |
|
| |
It would require a lot of power which wouldn't be available, and hands-on maintenance which would not be possible, during a journey like, say, Cassini-Huygens's seven year trip even before it begins its mission. |

They'd be a great deal more expensive, and more difficult to get to the planets in the first place. :) |
|
| |
I guess I'm saying (in the title) that even the optics already there may be good enough for interesting interferometery, for instance, asteroid hunting. |
|
| |
I would like to see how Earth looks from Venus.A 3 inch mirror (F6) would be all I need. I don't know what "interferometric" means, but that would be cool too.
<malopropism gone too far> Is interferometric when people stop others from using the metric system?</mgtf> |

1st2know -- see link for Earth image from Mars. |

I love that image, tc. First time I saw that, I was reminded of Lowell's canal maps of Mars and imagined what the long-thought-to-exist Martians percieved to be happening on that Earth planet. Fascinating image. Thanks for reminding me of it. |

Ah. I think I see what you're driving at - but I think you tripped yourself up with the Hubble reference, since that telescope uses different technology to your run-of-the-mill planet prober. |
|
| |
Detly -- agreed, just added comments to that effect. |
|
| |
Looking at that picture of Earth (and the Moon) from Mars, once again I'm just staggered by the beauty, loneliness and fragility of this ball of rock we call home. |
|
| |
[theircompetitor] - that image made my day!I can't see my house though, maybe we're gonna need a bigger lens.Must have more!! |
|
| |
I thought this was to make them look out better so they wouldn't get run over. |
|
| |
Look both ways before crossing the Milky Way. |
|
| |
I wish I could find the multihanded image of the genie from Aladdin -- before crossing, look here, here, here, here, here... |
|
| |
Doesn't interferometry require phase information to be preserved and combined? Surely this is not possible for visible light using any existing image capturing technology. |
|
| |
(Edit) It seems that IR and visible interferometry is in its infancy. The longest baselines achieved are in the hundreds of metres (link) |

- before crossing the street? - |
|
| |
Why did the probe cross the solar system? |
|
| |
To get to the other planet. |
