The Leonid MAC logo: a silhouetted human reaches beyond the limits of our knowledge, grasping toward the tail
of a comet. The orange stripe represents an upper region of the atmosphere where meteors vaporize and leave atomic debris behind that is responsible for the faint orange
glow of Earth's natural airglow layer.

2002The final
meteor storms in this Leonid storm season
double peaked over Europe and Northern America. Both storms were observed
as planned during a flight from Torrejon, Spain, to Omaha, Nebraska. Aurora
created a scenic background for a blizzard of tiny meteors.

2001The most beautiful of
all meteor storms in the Leonid storm season double-peaked
over Northern America and the western Pacific. The 2001 Leonid MAC covered
the first peak in a mission over the continental USA from Alabama to California.

No Leonid MAC mission because of relatively low meteor shower rates.
Airborne effort limited to small Cessna aircraft used to escape bad Florida weather and
moon light. Ground-based observers encounter the
1932 and 1866 dust trail on November 16/17 and 17/18.

1999The 1999 Leonid MAC mission patch features the flags of participating nations,
both nations from which participants originate as nations that are visited on our route.
The patch illustrates the multi-national and multi-instrument nature of the campaign,
symoblizing the global impact of meteoroids on satellite safety and the global
implications of our search for the origins of life. |

1998November 1998: the first airborne mission in this campaign executed over Okinawa, Japan.
This was NASA's first Astrobiology mission.
The mission featured the NSF/NCAR "Electra", with a 2-beam iron lidar of the University
of Illinois, and the USAF/452nd FTS "FISTA". | At work during1998 mission. |
