On Wednesday, NASA announced the launch of the probe Parker in 2018, which will be closer to the Sun than any other instrument, and it will touch its crown and will measure in a region of extreme temperatures never explored directly by man.
NASA explained that the Parker probe, named in honour of Eugene Parker, the astrophysicist who developed the theory of supersonic solar winds, will approach 6 million kilometres of the solar surface at a speed that will reach 200 kilometres per second.
For the first time, a mission will dare to enter the solar corona, a region full of mysteries, reaching temperatures much higher than the surface of the “sun king”, and that continues hiding secrets that only the astrophysical theory has dared to answer.
Parker, who was present this Wednesday at the event announcing the departure of this probe, stressed that this mission is a “heroic” milestone that until recently it was unthinkable due to the massive amounts of radiation, temperatures and speeds to which it would be subjected the delicate measuring equipment.
Launching a probe to approach to the Sun is a complicated undertaking, as the probe must accelerate as much as possible to approach Earth’s orbital speed, which will require the use of a Delta IV Heavy rocket, the most powerful in service, and the inclusion of a third phase of propulsion.
The Parker probe will travel seven times closer to the sun than any other human ingenuity and with a set of instruments will measure electromagnetic fields, solar winds and the extremely hot plasma structure surrounding the sun.
