One additional trend
KevinCBaxter   4/16/2014 4:35:40 PM
Okay the SpaceX booster recovery might not yet be a "trend", rather a recent game
changing development that will alter most future space launches. Their ability
to recover and reuse boosters will radically reduce the cost of launches and
will give SpaceX a unique advantage over competitors for some time, until they
all catch up.

Huge Jump in Processing Power
LarryM99   4/16/2014 7:54:18 PM
One trend that will be come evident in future missions will be a significant jump in processing capability. Recent tests have shown that current cellphone SoC's are as good at resisting radiation as the specifically hardened dinosaur CPUs that NASA has been using. We will be seeing a huge jump in sophistication of missions as a result and better power utilization. That still is primarily robotic missions, but it seems like the private sector is going to start driving more and more of the ambitious exploration.

@LarryM99: what is your reference, is the test data published?

I have a reference for the original test at http://www.nationaljournal.com/tech/why-nasa-is-firing-cell-phones-into-space-20130424 and I saw a presentation from Dr. Larry Matthies, who is a supervisor for JPL's Computer Vision Group. He is putting in a proposal for the next Mars mission with an autonomous flyer based on hardware like I described.

I have not seen published data, but my understanding was that lower voltages and smaller geometries significantly increased the resistance to radiation errors.

Astronauts and cosmonauts

One wonders if the astronauts and cosmonauts look down on the borderless Earth and ponder humankinds' stupidity.

You don't have to be up in space to ponder Mankind's stupidity.......

Ha, ha, that's true. But once viewed from the space, I could only imagine stupid things we do on earth would probably look even sillier!

Not a question of "if" but "when."

@LarryM99:

"lower voltages and smaller geometries significantly increased the resistance to radiation errors."

Was that a typo?   Do you have data backing up this claim?  

My understanding is that lower voltages and smaller geometries REDUCE the resistance to radiation errors, ie: for the ICs used in todays smartphones, exposure to radiation will increase the rate of occurence of data errors, compared to the older, larger ICs operating from higher voltages (5V).  I have heard that the old 486 was the last IC that US military would accept for radiation hardened applications.
