and the launch was successful... the next launch is tomorrow (22nd) at 0641utc - russian will launch soyuz fg launcher with fregat upper stage carrying several sats - one for russian govt, earth observation sat for belarus, technology demostrator for german dlr (german aerospace center) and some more...
the launch was successful... the next launch is soyuz-fg launcher with soyuz tma-05m spacecraft... it (she?) will carry malenchenko (rus), williams (usa) and hoshide (jpn) for the iss... the launch is scheduled on the 15th
today, at 2135utc begins the launch window for the next ariane 5 launch - with 2 commercial sats - one comm sat and one weather sat will be streamed live on arianespace.tv
today morning... atlas announced 5 sigma (and cms announced 4.9 sigma) for a new boson in the range the higgs is supposed to be (as well, they announced further investigation is necessary to evaluate if it has all properties of higgs or if it is a completely new particle)... and - both experiments did show basically the same results (which is good, of course, as it does not contradict the discovery)
on the nasa tv you can find several interviews with astronauts (iirc kelly, fossum) about the soyuz experience - launch, landing, flight, etc... edit: the next soyuz launch with a human crew is scheduled on the 15th (malenchenko, williams, hoshide)
afaik, they (ham) can listen to them... i am not sure, if you can contact them freely... i would say you can not... but you can try to ask them a question or so - through nasa/esa/rka - sometimes they have a briefing with the astronauts and allow the public to ask a few questions...
from nasa about warp/alcubierre drive (and more): http://ntrs.nasa.gov/archive/nasa/casi.ntrs.nasa.gov/20110015936_2011016932.pdf http://www.nasa.gov/centers/glenn/technology/warp/warp.html have fun

iirc: 'I can\'t figure out though how to calculate the actual position of the planet at a certain time when I know the semi-major axis eccentricity and inclination.' this is not enough to identify the position... as far as i remember, you need 6 things to uniquely identify the position (iirc, these 6 things are called 'orbital elements')... and just from the top of my head: if you know the orbit, then you would need at least one known position - a known position in any time... then you can calculate where the planet (satellite) is at any other time... of course, i could be wrong, it\'s been some time... and i guess i did not write everything and forgot something important...
