Hey steemian
what's up guys....
Today we have a special news for all... Parker Solar Probe - why is this mission is so important for us??
Us space agency Nasa has delayed Parker Solar Probe its mission to send a satellite closer to the Sun than ever bofore.
The parker Solar probe was set to launch from Cape Canaveral, Florida -America on 11.08.2018- Saturday , but at the last moment investigation have delay it for at least 1 day!!!!
It is now scheduled to take off- on board the Mammoth Delta-IV heavy rocket -on 12.08.2018 Sunday Morning.
the probe is set to become the fasted - moving man made objects in human history..
Nasa aiming to dip directly into our Star's outer atmosphere i.e corona.
Its data promises to crack longstanding mysteries about the Sun's Behavior assuming that it can survive with roasting super heavey temperatures above more than 1000++Celsius...
Why is this mission important for us for human civilization ?
Parker will help us better understand how the Sun works and it solar systems do.
The star is constantly nonstop bombarding the Earth with charged particles and magnetic fields. This perpetual flow, or "solar wind", is responsible for generating the beautiful auroral lights that appear in polar skies at any times, but there are some interactions that initiate much more troubling effects also there....
The biggest outbursts from the Sun will rattle the Earth's magnetic field. In the process, communications may be disrupted, satellites can be knocked offline, and power grids will be vulnerable to electrical surges quickly, which will be harmful for us. therefore we need to research on it deeply for solution not being hurted any more and can use it for our beneficial activity.
Scientists try to forecast these "storms" and Parker promises new and valuable information to help them do that; with that help of these vital data scientist will find out the exact causes for it.
Why Parker Solar Probe go so close to the Sun?
Parker wants to get where the action is happening, it will help parker to find out exact issue that causes these .
The corona is a remarkable place. It's strangely hotter than the Sun's actual surface, or photosphere. While this can be 6,000 degrees, the outer atmosphere may reach temperatures of a few million degrees.
The mechanisms that produce this super-heating are not fully understood yet. We need to investigate it properly.. therefore we need to send this space probe too closer to ever before.... source said.
How will Parker survive this is the big question and challenge for NASA's scientist.
A mission like Parker was first proposed 60 years ago, but it's only now that engineers have the technology available to keep a probe safe so close to the Sun. This is only for advanced technology ... by using it we can send these space probe too closer to the sun as never before.
Nearly everything on the spacecraft must sit behind an 11.5cm-thick (4.5in) carbon-composite sunshield. This will maintain all parts behind the barrier at a tolerable 30C.
The probe is solar-powered - obviously. But that in itself is a challenge because the solar cells will have to be moved into sunlight to work and they hate high temperatures.
So, Parker's arrays will be water-cooled, with the onboard computer system constantly adjusting their position so that only the minimum surface area absolutely necessary to generate power is exposed beyond the shield.
Autonomy is also crucial for this mission. Close to the Sun, the radio interference is intense, and Parker will be out of contact. The probe must manage any faults itself.
Above all, it has to keep the shield always pointing at the Sun to avoid being destroyed.
Thank you so much for the cosmic wonders that you are writing so beautifully so well.Hopefully beautiful writing of cosmic things from you are expecting.

Yes We need to know that is still unknown for us.. the solar storm which create lots of problems we need to be more cautious with this investigation.
