“와, 시작되는군, 우린 배우게 되는거야” 자신의 이름이 우주선 임무명으로 정해진 91세 과학자가 말한다
[시사뷰타임즈] 우린 이륙시켰다. 내서(나사)의 파커 태양탐사선 - 태양을 만질 것이라고 말들을 하는- 이 케잎 캐너버럴에서 발사됐다.
승용차 정도 크기의 이 위성은 일요일 아침 동부시각으로 오전 3:31에 훌로리더 기지에서 우주로 발사됐다.
이륙한지 채 2분이 안됐을 때, 내서의 지상관제소는 이 위성의 궤적과 비생상태가 “양호해 보인다”고 밝힐 수 있었다. “우리와 가장 가까이 있는 별의 신비를 밝혀줄 대담한 임무”
이후 7년 동안 파커는 태양계의 가장 큰 비밀들 중 몇 가지를 풀기 위해 구워버릴 것 같은 태양의 외기 속을 직접 통과하며 날아가게 된다,.
특히, 과학자들은 파커가 태양풍과 태양 에너지 입자에 대한 정보를 보내주게 되길 바라고 있다.
Parker Solar Probe: Spacecraft that will ‘touch the sun’ is successfully launched
'Wow, here we go, we're in for some learning,' says 91-year-old scientist who mission is named after

We have lift off. Nasa’s much-anticipated Parker Solar Probe – a spacecraft which it is said will “touch” the sun – has been launched from Cape Canaveral.
The car-sized satellite was blasted into space from the Florida base at 3.31am eastern time (8.31am BST) on Sunday morning.
Within two minutes of take-off, Nasa’s ground control were able to confirm its trajectory and flight “looked good”. A voice could be heard saying: “A daring mission to shed light on the mysteries of our closest star.”
Over the next seven years, Parker will fly directly through the sun’s roasting hot outer atmosphere in a bid to unlock some of the solar system’s greatest secrets.
In particular, scientist hope it will provide information about solar winds and solar energy particles.
The craft will be the fastest manmade object ever – flying at speeds of 430,000mph – and endure temperatures of more than 1,300C while looping round the sun a planned 24 times. At some points, it will move to just 3.83 million miles from the star’s broiling surface. It will constantly send back data to Earth.
Greeting the launch – on the back of a mammoth Delta-IV Heavy rocket – Nasa tweeted: “3-2-1… and we have liftoff of Parker #SolarProbe atop @ULAlaunch’s #DeltaIV Heavy rocket”.
One of those watching the historic moment was Dr Eugene Parker, the now 91-year-old scientist who first suggested the possibility of solar winds in 1958 and who the craft is named after.
“All I can say is ‘Wow, here we go, we’re in for some learning over the next several years’,” he said when asked how he felt.
He added: “It’s a whole new phase and it’s gonna be fascinating throughout ... and we’re just waiting for the data now so the experts can get busy because there’s a lot of data [that] will be coming in.”
Hundreds of thousands more people watched online around the globe with many sending messages of good will via social media.
The mission has been more than two decades in the making with the idea first proposed in the Nineties. However, it has now been enabled by the breakthroughs in thermal engineering that will allow the small probe to survive despite the blazing heat it will be subject to.
The successful launch followed an aborted take-off on Saturday morning when a last minute alarm caused it to miss its 65 minute weather window.
