The University of Arizona is spearheading work that would begin efforts to construct a space-based infrared telescope that could provide the capabilities NASA needs to search for asteroids and comets that pose impact hazards to Earth, called near-Earth objects, or NEOs.

Professor Amy Mainzer of the Lunar and Planetary Laboratory at the University of Arizona will provide technical leadership for the projected mission, to be in partnership with the Jet Propulsion Laboratory. The Near-Earth Object Surveillance Mission, or NEOSM, consists of a spacecraft, to be called the NEO Surveyor, that would continuously collect infrared images of near-Earth space, and the investigation team which will process, analyze and archive the data from it.

The spacecraft will use highly sensitive heat-sensing cameras to detect the infrared glow from asteroids and comets that are warmed by the sun as they get close to the orbit of Earth. Searching for asteroids by sensing their heat emission allows astronomers to not only detect their position and movement in space, but also measure their sizes and identify even the darkest asteroids that may have primitive, carbon-rich surfaces.

“This mission would answer a fundamental question: Are there asteroids or comets out there that can cause harm to the Earth over the next century?” said Mainzer, who also leads NASA’s Near-Earth Object Wide-field Infrared Survey Explorer, or NEOWISE, mission that uses an older spacecraft reactivated to hunt for NEOs after it completed its original mission. The NEO Surveyor builds on the success of the NEOWISE mission, which is celebrating the 10th anniversary of its launch on Saturday, December 14, 2019.

Thanks Gary, good to know we may have some warning of impending impactors.

I have managed to image a few close approach NEO's (up to mag 16) and used to wonder why I could record the trail of some, but found others difficult, based on their closeness and relative passing speed.

Having read the article, I now suspect the more difficult ones were less reflective, so it looks like I need to image in IR, if only I could find a high enough mountain near Brisbane.

Cheers

With all those ambers in the air you'll need Rick to build a rejection filter in PixInsight.

Hah, thanks Marc, but I think I'll just look for a vacant Lagrange Point where I can park my 'scope.

Cheers
