NASA will send into orbit the Sun the Solar Probe apparatus of Parker.
This will be the first in history a space ship that could get into the coronary region of the Sun.
“Part of the demonstration funding NASA technologies were used APL and our partners to UTAS to study the various refrigerants… But for the range of temperatures that we needed (from 10°C to 125°C) due to the many restrictions that water was an excellent decision,” says Mary Lockwood, systems engineer spacecraft Solar Probe Parker applied physics Laboratory of John Hopkins University (APL).
To increase the boiling point of water above the level of 125°C, it will be under pressure, and the de-ionization process will be to deprive the water of any minerals, which could have a negative impact on the operation of the system. Although TPS will be heated to 1370°C, the cooling system is designed to maintain the solar panels on a functional level when heated to 182°C or below. Flying through the atmosphere of the Sun, the panels will receive 25 times more solar energy than the Earth’s orbit.
NASA expects that during solar flight probe will be in the range of 6 million kilometers from the surface of the Sun. A special panel, whose width is 2.4 meters, is called the thermal protection system (TPS) will protect most components of the spacecraft from the primary thermal radiation. However, the solar panels of the vehicle will also be exposed to heat and require a dependable cooling system.
The difficulty of the mission will require Parker Solar Probe to move automatically and tune to the TPS was in the correct position to protect the ship. According to Lockwood, even changing the angle of the solar panels compared to the Sun would require to increase the degree of cooling by 35%.
“It is impossible to make these adjustments from the Ground, and this means that the system must coordinate… APL has developed many systems, including tilt angle, system piloting and power supplies, Autonomous software flight, working in conjunction with cooling system solar panels,” explains Lockwood.
It is assumed that the solar probe Parker will be one of the most Autonomous spacecraft ever released into space.
New solar spacecraft, NASA will observe how energy and heat moves through the solar corona, and also explores the behavior of the solar wind and energetic solar particles. This is important because the solar wind can disrupt satellites and affect power grids at the Ground. “We need to understand the space environment, just as sailors know the ocean,” says NASA on the Solar Probe Parker website.
