Members of the New York Air National Guard based at the Niagara Falls Air Reserve Station are heading to Australia to help set up a radar to track satellites and space debris.

Thirty-five Guard members from the 107th Airlift Wing’s civil engineer squadron are scheduled to leave later this week for the H.E. Holt Naval Communications Station in the state of Western Australia, where a radar is being relocated from Antigua in the West Indies.

In the three-week mission, guard members will renovate a building and construct a new antenna support structure for the radar, which will be the first low-Earth-orbit space surveillance network sensor in the Southern Hemisphere, the Air National Guard said in a news release.

The radar is expected to be in place later this year.
