The first time NASA tried to fly a telescope to the space station for an innovative study of meteors it was destroyed during a launch accident of an Orbital ATK Antares rocket.

Engineers used spare components to fashion a second meteor telescope and put it aboard a SpaceX Dragon cargo ship that launched eight months later. That too ended in disaster when the company’s Falcon 9 rocket failed.

On Tuesday, a third telescope is among the nearly 7,500 pounds of cargo packed aboard an Orbital ATK Cygnus capsule, which is slated to blast off aboard an Atlas 5 rocket between 11:05 and 11:35 p.m. EDT from Cape Canaveral Air Force Station in Florida.

The telescope will be placed inside the space station’s Window Observational Research Facility, or WORF, which uses a research-quality window in the U.S. Destiny laboratory.

Scientists want to use the telescope to learn about the size, density and chemical composition of meteor dust entering Earth’s atmosphere, the first space-based study of its kind.

They hope to use the telescope during the next big meteor shower, the Perseids, in mid-August.
