The inner border
The inner border
The Parker probe becomes the human object that has never been closer to the Sun.
In 1976 the Helios 2, a probe born of the collaboration between the USA and the Federal Republic of Germany, became the Icarus modern in approaching only 42.73 million kilometers from our star. Exceeding his sister by several million kilometers Helios 1, it marked a limit that would remain unattainable for decades, marking the inner frontier of human exploration. But that invisible barrier was sentenced from the moment the Parker was released, and yesterday, October 29, 2018, and more exactly at 1704 GMT, finally this line is left behind. We are entering unknown territories.
"Make
just 78 days Parker was launched, and now we've
closer to our star than to any other spacecraft in the
history", explains Project Manager Andy Driesman, of the Laboratory
of Johns Hopkins Applied Physics in Laurel, Maryland. "Is
a moment of pride for the team, although we remain focused on
our first solar encounter, which begins on October 31"
A record exceeded, and others will follow quickly. Helios 2 also established the brand for the fastest speed in relation to the Sun, 246,960 km / hour, but at 0254 GMT on October 30 this figure was exceeded. Juno still holds the record for maximum speed in relation to the land, with 265,000 km / h. Also that brand will jump to pieces. In your overflights closest to Sun, which will be just over 6 million kilometers from the Photosphere, will reach 690,000 km / h. It is literally setting limits that will surely remain unchanged for decades. If the Voyager and the New Horizons is expanding our borders to the stars, the Parker He is doing it to our own heart.
But its golden pages are about to be written. On October 31 will begin its first solar encounter, which will have the moment of minimum distance on November 5, when the probe, faced with heat and radiation conditions
brutal, will provide us observations of a
star unprecedented in history, helping us to understand the phenomena that
They have baffled scientists for decades. And it's just the beginning. The doors of the inner border are just opening.
The Helios 2, which for decades established the inner limit of human exploration.
On October 31 starts the first flyby, which will be followed by many others, closer and closer to our star.
