The predictable, regular showers are produced by debris from the tails of comets, and astronomers have been able to link certain events to comets that can even be seen today.

A meteor shower is a delight to astronomers and the public. We've built up a lot of legend and love for these "shooting stars", which some people even consider to be lucky. Never mind that if a falling object from space is too large, it can be anything but lucky for those on the ground!

Most of the material that falls during a meteor shower is obliterated. It starts as small chunks of rock, and burns up in the atmosphere. Sometimes, small traces of fine dust end up suspended in the upper atmosphere. This presents a great opportunity for scientists to collect it. High-altitude aircraft, such as the legendary U-2 spy plane, have been modified to perform dust collection.

Sample collection panels are deployed from the aircraft as it flies through the atmosphere, in the general area where a meteor shower has just taken place. Not much material is obtained this way, but it's cheaper than trying to go out and get this material in deep space.

More distant retrievals of cometary material have also been tried. The NASA Stardust mission flew closely to a comet and snared tiny particles from its tail. The spacecraft returned the samples to Earth inside a small capsule.

There's one intermediate step between the atmosphere and deep space that hasn't been used for sampling cometary dust. It involves trying to snare the particles in near-Earth space.

Sounding rockets are often used to send small instruments above the atmosphere for short periods. They are cheaper than satellite launches and produce useful data. A sounding rocket could, in theory, be sent on a mission to fly-swat a sample of stardust. The sample could be cached inside a protective capsule and parachuted to the ground.

In principle, such a mission would be difficult. The time of flight, and trajectory, would offer little chance of intercepting many particles, assuming any were caught at all. The apparatus needed to collect and safely return the samples would also be complex, and possibly difficult to place aboard a small sounding rocket.

Fortunately, a new means of carrying out such a mission will soon be upon us. Manned suborbital spacecraft will make their commercial debut in the years ahead. These vehicles are mainly being targeted at space tourists, and hundreds of people have already signed up to write them. But the scientific community is ready to use them, too.

The spacecraft will offer exposure to microgravity for several minutes at a price much lower than a flight to the International Space Station. Scientists are already undergoing astronaut training to fly on these vehicles and perform experiments.

Atmospheric studies have often been mentioned as one broad area for experimentation on these flights. But the spacecraft could also be used to collect samples of dust in the upper atmosphere, and even outside it. It would require modifications of certain outside components, and a lot of nerve to fly through a meteor shower, but it could be done.

Greater risks have been taken before with human spaceflight. In the event of a serious problem, gravity will pull the spacecraft quickly back to Earth, and the crew could even eject on some vehicles.

Some would point to the risk of damaging a spacecraft's thermal protection system, or heatshield, as being a source of major risk. Changing the orientation of a spacecraft during its flight to protect the most sensitive areas could allow this problem to be reduced.

Not every vehicle currently being proposed would be suitable for such a mission, but it could be achieved with some. One modified mission could see small suborbital sample rocket launched from a suborbital spacecraft, or from a carrier aircraft that normally carries a tourist spacecraft.

With so many new plans being drawn for this new era of cheaper access to space, it's worth examining the possibilities of sample collection along with all the other tasks we can perform.
