If all goes well, the University of North Dakota Aerospace (UND) Space Studies Dept. is planning to launch an unmanned, high-altitude balloon on Nov. 18 to track the Leonid meteor shower and (hopefully) collect extraterrestrial dust samples.
UND is not as state-of-the-art as NASA Marshall (which is also launching a balloon; see news release pasted on below)--we're on a shoe-string--but our "strato-balloon" team, using high quality balloons, is very good at building rugged instruments, as well as tracking and recovering payloads.
Recently, a UND Aerospace balloon reached an extremely high altitude (in "near space") on a recent flight. I'll keep you posted. It's an exiting attempt for us. Meanwhile, here's our strato-balloon project Web page with some great near-space images taken from past flights; cam is mounted on the payload gondola. The Leonid project probably won't be posted until after the fact assuming we launch the bugger!

"NASA Balloon Astronomers
Prepare for Leonids"
By Glen Golightly

HUNTSVILLE, Alabama * Astronomers at
NASA's Marshall Space Flight Center in
Huntsville, Alabama are preparing to launch their
third attempt to capture meteor particles and
show it all on video. They intend to release their
specially equipped, low-cost balloon at about
1:30 a.m. ET on November 18, to catch the peak
of the Leonid meteor shower.
Some astronomers are predicting a meteor storm
as the Earth's passes through the debris trail
scattered across its orbital path from the comet
Tempel-Tuttle at the end of a 33-year cycle. In
1966, up to 100,000 meteors per hour were
reported. A typical shower is usually about 10 to
20 meteors per hour.
If all goes well, the balloon should rise to about
100,000 feet in about three hours and descend
for 21 minutes until touchdown. As science
projects go, it’s about as economical as it gets.
Ed Myszka, a Ham radio hobbyist, built the
20-pound payload -- an aluminum box containing
a video camera and capture material that works
much like flypaper to trap particles no bigger
than a grain of sand. NASA contributed the
balloon and some other equipment.
The video signal and information about the
balloon’s location, altitude and air temperature
are downlinked to Marshall and posted live to the
World Wide Web. Local computer and amateur
radio enthusiasts will help track and recover the
balloon and its payload. The total bill runs to
about $4,000.
"It’s science on a dime," Myszka said. "We tried
it just for fun."
The scientists also launched balloons during last
August’s Perseids shower and last year’s
Leonids shower.
An estimated 80,000 people tuned in last year to
watch video from the Leonids Live! balloon and to
hear live commentary provided by NASA
astrophysicist John Horack, said Linda Porter, a
computer engineer at Marshall. This year,
organizers are hoping for even more people to
watch on the web.
"We caught the fireballs last year," Porter said,
referring to eight fireballs imaged by the balloon’s
video camera. "It’d be great if we caught a storm
this year."
Whether the Leonids storm, shower or fizzle out,
Myszka and crew will have to recover the
payload once it lands. Last year, the balloon
landed in a briar patch in bear country near
Chatsworth, Georgia.
Current weather predictions call for the balloon to
land in Tennessee about 127 miles
east-northeast of Marshall, but that could change
depending on upper winds at the time.
A global positioning system aboard helps
pinpoint the location. There are also placards
affixed to the payload asking anyone who finds it
to call and let the crew know.
So far the payload has always turned up -- but
usually missing one small item.
"People take the NASA logos as souvenirs,"
Porter said.
