"Success is not final; failure is not fatal: It is the
courage to continue that counts."
Now it is the end of our story, but not the end of our
discoveries and also not the end of this amazing mission, there are much more
to know and discover!
We hope that you, little astronauts, like this story which is
based on true actions and be interested in knowing more and more about this
mission and also other missions.
On February 25, the 11th approach to the sun has happened. It was nearly about 8.5 million kilometers from the sun’s surface and I was moving with speed of over 580.000 kilometers per hour.
On June 1, Parker solar probe completed its 12th close
approach to the sun and it was nearly about 8.5 million kilometers from the
solar surface, moving with 586.864 kilometers per hour.
On Sep, the 13th approach is expected to occur.

On January 17, the Parker probe was close to the sun at a distance of about 8.4 million miles, after that they launched about forty spacecraft and telescopes to help them observe the sun and the solar system.
On February 20, the Parker probe passed over the surface of the
planet Venus by curving around it and thus the planet's gravity will help it
bring it closer to the sun by increasing its speed, and this was the fourth of
seven aids from the planet's gravity.
April 29, was the first
time for touching the sun at a region called Perihelion with distance 6.5 million
miles away from the sun with speed exceeded 330,000 miles/hour.
On April 25, at the Johns Hopkins Laboratory, they received a
notification that data on the solar environment and the solar wind had been
collected, and that the collection would remain running until May 4.
May 15, the maneuver took about 39 seconds and changed speed by
91 centimeters per second (two miles per hour).
On June 2, they discovered diverse kinetic and magnetohydrodynamic,
aspects of plasma such as wave-particle interaction, magnetic field and
turbulence, pertinent to the heating and acceleration of the solar wind.
On August 13, the solar probe reached the same distance and speed
as he had traveled on April 29.
On October 16, the probe was moving about 15 miles per second and
was 2,370 miles away from the surface of Venus, and this was the fifth of seven
revolutions.
On January 29, Parker Solar Probe broke its own records as it
reached a speed of 244,255 miles per hour and revolved around the Sun at a
distance of 11.6 million miles.
On May 9, NASA's Parker Solar Probe began its longest
observation. The spacecraft activated its instruments at a distance of 62.5
million miles from the Sun's surface, the four instrument suites will continue
to collect data through June 28.
On July 5, NASA's Parker Solar Probe was at the right place to
capture a unique view of comet NEOWISE with its twin tails when it was
particularly active just after its closest approach to the Sun.
On July 11, the spacecraft came within 518 miles above Venus'
surface.
On September 27, this sixth solar encounter began closer to the
sun. Parker Solar Probe came within about 8.4 million miles of the Sun’s
surface while reaching a top speed of 289,927 miles per hour breaking its own
records for speed and solar distance.

It started its second solar encounter on March 30, 2019, and it
made its second perihelion (closest approach to the Sun) on April 4, 2019 at
6:40 p.m. EDT, where it was at a distance of 15 million miles from the sun with
a speed of 213,200 miles per hour, this solar encounter lasted until April 10.
During this solar encounter the amazing design of the solar probe helped us to
store a lot of data.
The main purpose of that great mission is to know more and more
about the mysteries of the sun, so after the second solar encounter has
succeeded, the monitoring team of Parker Solar Probe decided to extend science
observations as the spacecraft approaches its third solar encounter, as Parker
Solar Probe turned on its four instrument suites on Aug. 16, 2019 — earlier
than during its previous two solar encounters, extending the observation period
from 11 days to about 35 days, which made us know more information about the
sun.
At just before 1:50 p.m. EDT on Sept. 1, 2019, NASA’s Parker
Solar Probe completed its third perihelion, at the time of perihelion, the
spacecraft was about 15 million miles from the Sun’s surface, traveling at more
than 213,200 miles per hour, and this third encounter differs from the first
two solar encounters in having longer time to collect more data.
On November 12, 2019, NASA’s Parker Solar Probe team released
scientific data collected during the spacecraft’s first two solar encounters to
the general public.
On December 26, Parker Solar Probe successfully completed its
second flyby of Venus. The spacecraft used Venus to slow itself down,
approaching the planet at a distance of about 1,870 miles from Venus’s surface
during the second gravity assist of the mission. As the Solar Probe uses Venus
to be ready for the next solar encounter to approach the sun at less distance.

Parker
solar probe completed successfully its first trajectory correction maneuver.
This
maneuver will allow Parker Solar Probe to come within about 3.83 million miles
of the sun surface on its closest approach in 2024.
Parker
Solar probe was launched by about 1.1 million names that will be launched on
the sun
On September
13, Parker Solar Probe’s first of its kind water cooled solar array cooling
system was made fully operational.
On
September 25, 2018, Parker Solar Probe captured a view of Earth as it sped
toward the first Venus gravity assist of the mission.
On
October 3,2018, Parker Solar Probe successfully completed its flyby of Venus at
a distance of about 1,500 miles during the first Venus gravity assist of the
mission.
Parker
Solar Probe surpassed 153,454 miles per hour as calculated by the mission team
making it the fastest-ever human-made object relative to the Sun. This breaks
the record set by the German-American Helios 2 mission in April 1976.
On January 14,2020
NASA’s Parker Solar Probe recorded the sound of plasma when its waves
quickly shift from one frequency to another as they move through the solar
wind.
Also, the probe recorded the sound of dust
from asteroids torn apart by the Sun’s gravity and solar heating. These
particles stripped from comets strike the spacecraft at speeds close to a
quarter of a million miles per hour. The probe was protected already from the
dust
On May 9,2020
The nearly two-month campaign is spurred by Parker Solar Probe's
earlier observations, which revealed significant rotation of the solar wind and
solar wind phenomena occurring much farther from the Sun than previously
thought.
NASA explained that the clouds surrounding Venus block most of the light surrounding it, but the longest visible wavelengths make it pass, and while red light is mostly lost in daytime images, the only way WISPR allowed to see the temperature of the planet when it passes at night. This opportunity came with a flight on February 2021, and it was the mission's fourth flight on Venus when the spacecraft passed close to the nocturnal planet for the first time, so WISPR picked up wavelengths ranging from near infrared to visible.

The solar probe has faced some challenges while carrying out its
mission, among these challenges:
There were some problems in the testing and the software of
Parker Solar Probe, so the launching was delayed to August 12, 2018.
On January 14, 2020, NASA's Parker Solar probe recorded another
sound resembling old TV static, that sound is actually the dust from asteroids
torn apart by the Sun’s gravity and solar heating. These particles stripped
from comets strike the spacecraft at speeds close to a quarter of a million
mile per hour.
On April 28, 2021, during its eighth flyby of the Sun, Parker
Solar Probe encountered specific magnetic and particle conditions at 18.8 solar
radii (about 8.1 million miles) above the Sun's surface, telling scientists
that it had crossed the Alfvén surface (the boundary separating the sun's
corona from the solar wind) for the first time and finally entered the solar
atmosphere.
On Feb 15, 2022, the large solar prominence blasted tons of
charged particles in the spacecraft's direction but the spacecraft was built to
withstand activity just like this to get data in the most extreme conditions.
The spacecraft team has noticed that occasionally the star tracking cameras used as part of the guidance and control system see reflected light from dust and shattering particles that can momentarily disrupt their ability to see stars, however this doesn’t compromise the safety of spacecraft or instrument operations, as the star trackers aren’t the spacecraft’s only method of controlling where it points.

"At NASA, we make Air and Space available for everyone"
NASA never stopped or never will stop doing impossible things.
This book truly shows you one of the greatest missions that was
started by NASA in 2018 and is supposed to end in 2025, the mission is done by
parker solar probe to discover the sun and know about the mysteries of the sun.
Parker solar probe was designed and managed by NASA's Goddard
Space Flight Center / Johns Hopkins University Applied Physics Laboratory.
Parker solar probe consists of four science instruments and these
are the most important thing to mention as these four science instruments are
really essential in collecting data and discovering more and more about the
sun, the spacecraft’s four instrument suites help scientists to answer outstanding
questions about the Sun’s fundamental physics — including how particles and
solar material are accelerated out into space at such high speeds and why the
Sun’s atmosphere, the corona, is so much hotter than the surface below.
This well designed and managed solar probe is supposed to achieve 24 planned orbits around the sun at the end of the mission and complete seven Venus flybys over nearly seven years to gradually shrink its orbit around the Sun, coming as close as 3.83 million miles (6.16 million kilometers) to the Sun and about seven times closer than any spacecraft has come before.

Parker Solar Probe was the first NASA mission named for a living
person.
In honor of Eugene Parker, eminent physicist who first predicted
the solar wind. NASA announced in May 2017, that it would rename the Solar
Probe Plus mission to Parker Solar Probe, the mission was conceived in 1958,
but it took 60 years to develop the technology to make it happen.
NASA's historic Parker Solar Probe mission is revolutionizing our
understanding of the Sun, where changing conditions can propagate out into the
solar system, affecting Earth and other worlds. The primary science goals for
the mission are to trace how energy and heat move through the solar corona and
to explore what accelerates the solar wind as well as solar energetic
particles, to perform these unprecedented investigations, the spacecraft and
instruments are protected from the Sun’s heat by the Thermal Protection System
a 4.5-inch-thick (11.43 cm) carbon-composite shield, which needs to withstand
temperatures outside the spacecraft that reach nearly 2,500 F (1,377 C).
Parker Solar Probe took images and records of the sun and the
space weather to know a lot of information and to predict what can happen to us
on our Earth as for example the Earth’s ionosphere is important because it
reflects and modifies radio waves used for communication and navigation some
phenomena such as energetic charged particles and cosmic rays can contribute to
the ionosphere, Other solar phenomena such as flares, and changes in the solar
wind and geomagnetic storms also effect the charging of the ionosphere.
