Two Rockets Fly Through Auroral Arc

Early Thursday morning, two sounding rockets simultaneously flew through the veil of an aurora collecting data from both the top and bottom edges of the arc. A team from the University of Iowa waited for precise conditions before launching two different NASA Black Brant rockets from the Poker Flat Research Range near Fairbanks, Alaska just before 1 a.m. Alaska Standard Time. Other rockets have flown through aurorae previously, but this is the first time two rockets were used together. As part of the Auroral Current and Electrodynamics Structure (ACES) mission, the flights will provide insight on the structural subtleties of the aurora, details that researchers may have missed when previous measurements were done using only a single vehicle.

A two-stage Black Brant IX rocket launched at 12:49 a.m. and reached an altitude of more than 226 miles and flew for just under 10 minutes. At 12:50 a.m., a single-stage Black Brant V launched, reaching an altitude of nearly 83 vertical miles, flying for roughly eight minutes.

Principal Investigator Scott Bounds of the University of Iowa said the payloads of each ACES rocket performed well during flight, and the ACES team will begin to analyze all of the data collected, which should keep them busy for the next year. Bounds said this information will help refine current models of aurora structure, and provide insight on the high-frequency waves and turbulence generated by aurorae.

The rockets have been poised for launch since January 14, waiting for the right conditions. A stable, thin arc was required for the experiment to perform optimally and finally that arc appeared early on Jan. 29.

    …rockets can’t make pancakes =)

    Lets’ just say I’m glad rockets that can travel a few miles are outlawed for private citizens!

    ‘rockets can’t make pancakes’
    ROTFLMAO that has to be the first time
    I heard that phrase,LMAO hahahahaha

    Anonymous I laughed so hard my stomach hurts, it took me 10 minutes to settle down. That’s the best laugh I had in a week! lol

    Actually,
    rockets CAN make pancakes!!!!!

    When we fly them, and the recovery system does not work as planned, the recovered splat on the earth is quite a pancake. A flat, metallic pancake that will bring great amounts of indigestion to the PI that wanted to get it back to fly again.

    Sooooo,
    while not fun,
    rockets CAN make pancakes!

    djk-you give great understandable clear description. I read a book in a series that followed ‘the science of star wars’ and describes why should those hugh alien ships hovering over the big cities in the movie’ Independence Day’ have to do anything else,just hovering would have flattened the cities into a flat pancake, but the truth would not make much money!!
    Still, when I first say the answer
    ‘rockets CAN make pancakes!!!!!’ I had a great laugh. I would not want that pancake you describe lol.
