PAMELA - satelite mission for Dark/Antimatter Research

Barkster! Good to hear from you.
How do Pamela's objectives compare to those of the LHC? Aren't the cosmic ray collisions more energetic?
From Pamela > Scientific Objectives it's stated that a couple of the observational objectives are:
And from the LHC MACHINE OUTREACH page, it's stated that proton-proton collisions are expected to be at an energy of 7 TeV per beam (scheduled for 2007).
Is there a chance that Pamela can also possibly provide observations of extra dimensions, aside from helping to answer questions about dark energy / dark matter ?
Pamela (not Anderson) has

Pamela (not Anderson) has been launched! It looks like elementary particle physics is looking again to cosmic rays and not accelerators as sources of high energy particles. In the past, cosmic rays observatories used to be in high altitude places like the Testa Grigia Observatory near Mt.Cervino at 3500 meters, from which you could ski down to Cervinia (2000 meters) on the Ventina trail. Happy days!

Glad to be back, Chipper... Thanks.
Although I have to admit with all sincerity that duty in Iraq quite often seems preferrable to my current job in DC.
Obviously, my mind has lately been distracted from scientific subjects not directly related to killing terrorists (remember, I'm an electronic warfare guy).... so I can't even begin to answer your questions about the PAMELA program goals or technology. But I thought it encouraging that the study of astrophysics was going to space again in another satelite experiment and just wanted to share the good word.
Cheers,
Glenn

Cosmic rays have higher peak

Cosmic rays have higher peak energies, but aren't as common as the impacts in a particle accelerator. The higher energy (more chance of something interesting happening) is partially balanced by the lowr occurence of impacts. I'm not sure how exactly the two factors add up.
