| Everything of course only if publically available:
|

|
| - what is their trajectory/target location?
|
| - what does the data look like being transmitted (I.e. Voyager

|
| - what Kind of data could be still gathered, e.g. could we ask
| the Probe to ,,take a picture" or would the bandwidth simply not
| be enough?

| According to [1], as we speak the DSS 14 antenna at Goldstone
| is receiving Voyager 1 data at a whooping 160 bits/sec.

| How quickly is the bit rate degrading from Voyager?
|
| Like if it's 160 bits per second now, how long until it's 100
| bits per second? 10? 1?

| Very nice site!

| Although, many links to data are broken, that is very
