HAARP’s Antenna Array: The Test Kitchen in the Sky

This week, we explore the High-Frequency Active Auroral Research Program (HAARP), a joint Air Force and Navy endeavor to enhance radio science, surveillance, and space systems.  Below, HAARP researcher, Dr. Todd Pederson, recounts his sub-zero journey to the HAARP Antenna Array north of Gakona, Alaska.

Questions about HAARP? The HAARP management team joins our live webcast, Wednesday, Feb. 24th at 2pm eastern. Special thanks to Michael Kleiman, 377th Air Base Wing, for co-producing this series.

Dr. Todd Pedersen is a space physicist serving with the Air Force Research Laboratory, Space Vehicles Directorate’s, Battlespace Environment Division, Hanscom Air Force Base, Mass. He got his start as an experimenter early in life playing with magnets, wires, and other fun stuff salvaged from old radios, motors, and cars.

It’s the week before Thanksgiving, but the temperature is already 37 degrees below zero. The dashboard lights dim as the rental car engine slowly turns over, but thankfully, it starts and I am on my way for another day.

Every bit of snow tracked into the car on my boots over the last two weeks is still there on the floorboards, frozen squeaky solid. It is enough if the heater will keep a spot on the windshield, in front of me, clear of snow and ice. The tires thump as I drive slowly up the hill—-they will go back to being round after they warm up a bit and can flex a little more, but for now, the side frozen flat against the ground all night stays flat.

The blue-gray twilight over the volcano reflects off the shiny ice covering the highway. In Japan, this mountain would overshadow Mt. Fuji, but here, looking out over the Wrangell-St. Elias National Park in south central Alaska, it’s just another 15,000 foot volcano. But I’m not here for the scenery, and certainly not here for the weather. I’m here for the ionosphere, and a huge 30-acre antenna array that lets us do experiments with it.

I arrive at the HAARP facility–the fancy name for the antenna array and its associated power supplies and instruments–40 minutes later, look at the latest readings from the instruments on the Web site, and start planning the details of the evening’s experiment.

The ionosphere is a plasma, created by sunlight, and in this part of the world, electrons shooting down to form the aurora. Unlike plasmas created in laboratories, light bulbs, and gift-shop gizmos here on Earth, the ionosphere isn’t trapped inside a bottle and has no walls to siphon off the particles. It’s the same problem as trying to make clouds in a jar. Instead of a cloud in the middle, all the moisture sticks to the edges and you just get foggy glass.

The big antenna out there sends out radio waves at just the right frequencies to resonate with the ionospheric plasma, kind of like wiggling a block of jello. When everything works just right, the wiggling can break the plasma up into long parallel strands like a handful of uncooked spaghetti. Only these noodles are 20 or 30 miles long and start 100 miles up. The same thing also happens naturally, as the ionosphere rises and falls and gets pushed around by currents in the solar wind and upper atmosphere.

As you might expect, the bundles of plasma spaghetti do not play nicely with radio waves passing through them, so an ionosphere full of these is unkind to global positioning system signals, radar beams, and satellite links our high-tech troops depend on to keep the pointy end pointed at the bad guys and the good guys safely out of harm’s way. The big antenna array out there is the only lab we have where we can actually study the ionosphere through controlled experiments–a test kitchen in the sky if you will.

Another glance at the Web site shows today’s ionosphere developing very nicely. Tonight, I’ll add a little FM sweep at 2.9 Megahertz to the recipe. It might be perfect with spaghetti.

One Response to HAARP’s Antenna Array: The Test Kitchen in the Sky

    Wife of SRB427 here, it was either during the year 2006 or 2007, then was the time I have seen the most rainbow clouds in my life. I called them rainbow clouds and learned the term iridescent clouds. The best display, me and my husband saw looking up in front of our garage after backing up into our driveway from doing errands, was a large cloud moving slowly over the sun. The cloud as it flowed by was changing brilliantly every color of the rainbow. It appeared as though a laser artist was controlling that cloud. Was that you Dr. Todd Pedersen? Anyways, sunlight does split among clouds of ice crystals and ice dispursed in the atmosphere creating rainbow rings around the sun and moon, arcs, and sundogs. But we enjoyed the show. I have heard and read a lot of bad things about HAARP. There is a lot of distrust about this fascility and our government all together. It’s human nature when playing with power and technology, at times creates wrong decisions. Playing with toys when we were kids helps to become creative and solve problems. All the knowledge, technology and powerful toys humanity uses today, we need to use it to balance our planet. God authorized us to be stewarts to care for the only home and school we have. Many of the scary noises, shaking, and light displays reported is aimed at HAARP, but people do create their own special effects for media attention with the software, Iphones and Ipods, etc. I know Area 51 and HAARP are doing special effects that are unavoidable to see with their projects too. May this power and technology be used to create with God in supporting mankind, Earth, our solar system, and beyond, not to control for destruction. All this stuff is awesome and would like to have this put to good use and not to endanger and scare the hell out people who help support all this with the tax dollars. Glad to know the ionosphere is developing nice. Anyway, keep up the good work Dr. Todd Pedersen and along with the Megahertz sauce over spaghetti, put on a rainbow light show for me! Thanks for your time reading my comment———Audie
