NASA Can Now Predict Solar Flares!

by AB7RG  2023-03-07
Solar flares can be very dangerous for the power grid, satellites, even mobile phones. How dangerous a flare can be depends on how powerful it is. If a warning is received by NASA and other space agencies on time, the impact on Earth and humanity can be lessened. Now, NASA has got a solution for the same. Yes, NASA has said that it can predict Solar Flares. Scientists can now predict when and where the Sun's next flare might explode. The crucial role is that of Sun "Flashes".

Student-Built Satellite Uses Beach Ball for Antenna, Helps Study Ionosphere

by AB7RG  2023-03-08
Scientists and engineers at the University of Arizona have built instruments for three NASA telescopes, led two deep space missions and made it possible to see farther back in space and time than ever before. Adding to this list of space exploration accomplishments is a different type of project -- one led entirely by students. If everything goes according to plan, the satellite won't just demonstrate new space technology; it will also probe the ionosphere -- a layer of charged particles at the boundary between the Earth's atmosphere and space -- so that the team can better understand the ionosphere's ever-changing structure. This structure impacts the propagation of high-frequency radio signals. On the opposite end of CatSat's inflatable antenna is a "whip" antenna, about 2 feet long and shaped like a protruding stick. It was designed to receive low-power, automated, high-frequency beacons from thousands of Earthbound amateur radio enthusiasts. Radio signals in the high-frequency range can bounce off or refract from the ionosphere and travel to far-reaching locations by "bending around the Earth." Amateur, or ham, radio takes advantage of this charged layer of the atmosphere to broadcast information all around the globe.

Astronauts Will Be Reached by Students with Amateur Radio:

HONOLULU (KHON2) -- As part of the Amateur Radio on the International Space Program, which promotes STEM opportunities, students from Lana'i High and Elementary School will talk with astronauts on the International Space Station using an Amateur Radio on March 20, at 9:09 a.m. ARISS said that the school's contact with the International Space Station will happen using a Telebridge connection with ham operator Jan Poppeliers ON4ISS in Belgium. The astronaut to be interviewed may be one of the following: Warren Hoburg KB3HTZ, Steve Bowen KI5BKB or Sultan Al Neyadi KI5VTV.

How to Generate and Learn Morse Code Using the Linux Terminal:

by AB7RG  2023-03-06
Morse code may be less important these days for communication, but it's worth learning for some applications. One of the best ways to learn Morse code is to hear it. If you use Linux, there's a command-line program that can help you do just that. It's called morse. This program translates any text into the audio dots and dashes of Morse code.
