how big are the risks that that could end the missionon? >> the risksks are tremendous. i mean, definitely this is the fifirst for humanity. we have never done this before. we havee nevever sent a spapacet to such a lethal environment. we have to remember that jupiter is the giant amid so much radiation, like electron bullets thatat would penetette anything. the spacecrcraft has a shield, f we can call it like t tt, is a cucubeade out of tighthtanium tt will s shield t the most sensite portions of the spacecraft, thee electricalal opponentsts, to tht enormomous radiationon fieldld e have mititigated those risks.. we havee tied to comomplete the scenararios. we are confifident wee have done everything we could to me this mission a success. sarah: assuming the mission is a success, what do you hope it will tell us about jupiter? when are we going to see the beautiful new high-resolution imageses beamed back? >> well, we hope to ---- what we have been doing is actualllly duringng approach phase, that we'r're just about to complete, basically we have been taking justst infor

anthropogenic interference with the climate, which is what the ipcc was originally charged w wh as their missionon, arguably you should not downplalay the higher-end scenarios if they're credible, even if f they're loww probabilityty outcomes. if ththr probability i isn't zero, then they should contribute to t the assessment of risk much in the way t that, you know, we buy fie insurance for our homes nott becauause we think our homes are going to bururn down. that's a very rare occurrence. it's very unlikely to happen to o us, but even thohough its probability is very l low, the magnitude of co, the impact on our lives if our house was to o burn down is immeasurable. mitigating climate change, , doing somemething abot our carbonon essioions ia plananetary insurance policy, ,d in guiding the teterms of that insurance policy,y, we need t te focucusing on some of those potentialal more extreme catastrorophic outcocomes. if te ipcc systematically downplays those e outcomes, then it dodo't serve ththat largeger process of societal risk assessment as it should. qualitatively speaking, if you look at imp

it's now ready to 20-month, $1.1 billion missionon to learn more about the biggeste planet in the solarm.yste >> what feeling.ing. a mission of this complexion iso the to accomplish tonight is i just truly amazing. amazi >> reporter: rival wasival was dramatic with juno firing itsins rockets on auto pilot because of time lag between jupiter ander a earth.rt juno is completely powered by sunlight.nl its camera and other instrumentr were shut off for the arrival to save energy. energ but project managers say they're not worried about a lack ofabt a power.powe >> even though we're receivingng only 125th of the sunlight at jupiter that we would at earth,, these massive are a race provide over 500 what's of power.fow >> reporter: now that ash bitast has been chief the focus turns r to the recon mission.. peering through jupiter atmosphere to map the interior sign lifts looking forward to to unlocking planet's mysteriesri which could tell us more abouteo how the solar system itself developed.de >> for centuries, we have a imagined how the planets move and how the stars move, andnd we've only
