With current technology, we are able to easily send a probe to the Alpha Centauri star system at a speed of about 20 km/s (velocity of voyager probe), which means it would take about 65000 years to get there.
In light of this, suppose we sent a probe capable of delivering 100g of biological material to an Earth-like planet in α-Centauri.
Are there organisms that:
- Could survive the journey, perhaps frozen or in a dormant state;
- Would have a fair probability of surviving in the barren oceans (or land if preferred);
- Eventually have a change of evolving to more complex lifeforms?
If possible, give a rough estimate of how likely you think that would be -- would we need to send 10 probes for a good chance, or billions of probes?
The lifeless environment seems to necessitate either photosynthesis or chemosynthesis to survive. But what about the necessary food (organic matter)? Would any of those restriction make it virtually impossible to achieve long term life with current goals?
