Lackluster Meteor Shower Sets Stage for Big Show in 2011

The Earthwill pass through the cast-off remnants of an ancient comet Friday(Oct. 8),but the resulting meteor shower will be lackluster at best, expertssay. Yetthe event sets the stage for a truly remarkable shooting star displayin 2011.

The sourceof this annual October meteor display, called the Draconid meteorshower, isdust and debris leftover from Comet Giacobini-Zinner.

This year,according to skwatching experts, will be no different. But by allaccounts,2011 will be a year to remember for the Draconids.

"Thisyear, forecasters expect Earth to narrowly miss several of the debrisstreams,resulting in no appreciable display for 2010," reportedSpaceweather.com,a website dedicated to monitoring space weather and sky events. "Nextyear, however, could be different. On Oct.8, 2011, Earth will have a nearhead-on collision with a tendril of dust, setting off a strong outburstof asmany as 750 meteors per hour."

In fact, the2011 Draconid meteor shower is expected to be so astounding that NASAhasalready begun preparing for the riskto satellites orbiting Earth such as the International SpaceStation orHubble Space Telescope.

"We'realready working with NASA programs to deal with spacecraft risk," saidWilliam Cooke, a scientist with the Meteoroid Environment Office atNASA'sMarshall Space Flight Center in Huntsville, Ala., during an interviewwithSPACE.com in June. "I imagine when the word gets out there will be aDraconid outburst, I'll get the usual calls from Comsat companies aswell asgovernment space programs."

In additionto the chance of dings, there is the possibility of electrostaticdischarges associatedwith the collision between a meteoroid and a satellite, Cooke said.Suchdischarges can account for a significant fraction of spacecraftanomaliesduring meteor showers, he added.

While thisyear's Draconid meteor shower will likely be a bust, the 2011 Draconidsshouldbe a sight to behold, forecasters said. 

The bestvantage points will be Europe, Africa and the Middle East,Spaceweather.comreported.

The 2011Draconids could possibly be the most powerful meteor shower since thedazzlingLeonids display 10 years ago, the website added.
