Berthoud meteorite rocks scientists

BOULDER - Out of a clear blue sky, a bit of space history as old as the
solar system and no bigger than a softball slammed into the soft, wet
earth beside a Berthoud family's home Oct. 5.

John Whiteis saw light and a little bit of dirt move. His wife, Meghan,
saw a dark streak. Their 19-year-old son, Casper, heard something like this:

"Wsssssssshh. Thud!"

"We were kind of trying to figure out what we had just witnessed," said
John Whiteis, a former auto mechanic and self-described Star Trek fan.

At first he thought it might be a piece of a passing plane. But there
were none overhead.

Maybe a model rocket launched by a neighbor, they wondered. Nah.

A few moments passed before the family realized what they had just seen:
a shiny, black meteorite plunging at more than 100 mph into a pasture,
just 75 feet from their home.

Scientists say meteorites pepper the Earth's atmosphere daily, almost
every hour. Most burn up as "shooting stars." Some land in sizes as
small as a grain of sand.

The Whiteis family, however, witnessed only the fifth confirmed sighting
of a meteorite hitting the ground in Colorado since 1924.

On Monday, the family gathered at the University of Coloradoto talk
about their discovery along with a panel of geologists and astronomers.

Judging by their reactions, it was a close call as to which group was
more excited by the find: the family or the scientists.

"Isn't this exciting?" CU geologist Steve Mojzsis gushed. "Thank you for
bringing the meteorite in."

CU planetary scientist Nick Schneider described his reaction when he
first heard Casper Whiteis' rendition of how the meteorite sounded as it
landed.

"I got chills up and down my spine hearing that description," Schneider
said. "I get a zing from this rock."

"This came from outer space. It probably took a million years to get
here," he added. "If you're feeling a little bit old, just come and
touch this and it'll put things in perspective."

If not for some furniture the Whiteis family bought at an auction last
weekend, this meteorite might have fallen to earth unseen.

It rained on Monday, so the furniture stayed in the vehicle. On Tuesday,
John Whiteis was home from work early, so in came the furniture. And
down came the meteorite.

It took the family about 25 minutes after impact to locate the meteorite.

A smooth black surface about the size of a golf ball peeked out from
under the dirt.

John Whiteis turned back to the house to get a shovel. But before he
could get there, Casper had grabbed a hammer and dug it out of the earth.

By then it was cool to the touch, said Casper, an aeronautics
engineering student at AIMS Community College, who hopes to study at CU
some day.

While meteorites have value to collectors and can fetch up to $1 a gram,
the Whiteis family say their two-pound meteorite is not for sale.
Instead they plan to let CU scientists study the rock and put it on
public display.

Scientists at CU also hope to study the meteorite and compile other
eyewitness accounts of any fireball sightings that day to determine its
trajectory.

On Saturday, with permission from local property owners, scientists and
volunteers hope to search up to four square miles of the area around the
Whiteis home for other fragments.

conference Monday at the University of Colorado Discovery Learning
Center in Boulder. The meteorite landed in their back yard Oct. 5 and
they are providing it to CU researchers for scientific analysis.

Rock of ages lands in couple's backyard

By Katy Human
Denver Post Staff Writer

A time capsule fell into a Berthoud backyard last week.

Megan and John Whiteis walked out their back door on the afternoon of
Oct. 5 as a softball-sized meteorite streaked over their heads, plunging
itself into a horse pasture about 100 feet away.

"It sounded like a pretty good- sized model rocket, only like it was
going down instead of going up," said Megan Whiteis. "Then it hit ...
with a pretty good thud."

Colorado scientists and others are now probing the stony meteorite - one
of only five in the state's recorded history ever to be seen in the sky
and then found on the ground - for information about the Earth's birth.

"Meteorites are the leftovers, the table scraps from the solar system
that tell us about our origins 4.5 billion years ago, when the planets
formed," said Steve Mojzsis, a University of Colorado geologist.

The meteorite is scientifically valuable for a variety of reasons,
including its rare composition - only about 5 percent of all meteorites
that fall to Earth are composed of the lava-like material found in this
one, Mojzsis said.

He speculated that it might have broken off Vesta, an asteroid about 325
miles across that lies in the belt between Mars and Jupiter.

Also, the meteorite may still be emitting gases that were trapped inside
because of the chill of space, said Scott Palo, an aerospace engineer at
CU who is overseeing scientific study of the meteorite. Those gases
could help scientists understand how our own planet - essentially a
collection of meteorites that clumped together - generated its
atmosphere, Palo said.

Moreover, he said, he hopes scientists will be able to reproduce the
object's trajectory through the atmosphere, to better understand where
it came from. During the past several years, many fireballs have
streaked through Western skies in early October, possibly because of
their location in space relative to Earth.

The meteorite may be part of a bigger one that split up in the atmosphere.
