How does WISPr work?
How does WISPr work?
WISPr authentication allows a “smart client” to authenticate on the network when they roam between Wireless Internet Service Providers, even if the wireless hotspot uses an ISP for which the client may not have an account. default WISPr user role to that client.
What IS WISPr authentication?
Wireless Internet Service Provider roaming (WISPr) authentication allows a smart client to authenticate on the network when they roam between wireless Internet service providers, even if the wireless hotspot uses an Internet Service Provider (ISP) with whom the client may not have an account.
How does the Parker Solar Probe work?
So, to keep its cool, Parker Solar Probe circulates a single gallon of water through the solar arrays. The water absorbs heat as it passes behind the arrays, then radiates that heat out into space as it flows into the spacecraft’s radiator.
What is Wspr ham radio?
WSPR (pronounced “whisper”) stands for “Weak Signal Propagation Reporter”. It is a protocol, implemented in a computer program, used for weak-signal radio communication between amateur radio operators. The protocol was designed, and a program written initially, by Joe Taylor, K1JT.
How did Parker Solar Probe not melt?
The panels are protected by a simple cooling system that has a heated tank, two radiators that will keep the coolant from freezing, aluminum fins that increase the cooling surface, and pumps.
Will Parker Solar Probe touch the Sun?
Parker Solar Probe is the 1st spacecraft to touch the sun. For the first time, a spacecraft has literally touched the sun. Scientists made the announcement this week (December 14, 2021) at the American Geophysical Union meeting in New Orleans.

How hot will the Parker probe get?
That translates into 5.5 MW of sunlight pounding on the spacecraft’s front surface. The probe is designed to reflect much of the incoming light away, but even so, exposed surfaces will get as hot as 1500 °C.
Did NASA really touched the sun?
The National Aeronautics and Space Administration (NASA)’s Parker Solar Probe touched the Sun. The Parker Probe entered the Sun’s upper atmosphere known as the corona where the temperature intensity is up to 2 million-degree Fahrenheit. This is the first time that a spacecraft has reached this close to the Sun.
