WASHINGTON (NAS PR) — The likelihood of a large asteroid hitting Earth in any given year, or even over one’s lifetime, is very small. However, the consequences of such a strike would be great. Detecting near-Earth objects (NEOs), determining their orbits, and estimating their mass is critical knowledge necessary to quantify their destructive potential.

A new report titled, Finding Hazardous Asteroids Using Infrared and Visible Wavelength Telescopes , from the National Academies of Sciences, Engineering, and Medicine analyzes the advantages and disadvantages of telescope capabilities in detecting NEOs and says that space-based infrared NEO survey telescopes are more effective than visible wavelength telescopes, provide diameter information that visible wavelength telescopes cannot provide, and do not cost significantly more than in-space visible wavelength telescopes.

The report also says that if NASA develops a space-based infrared NEO survey telescope, it should also continue to fund both short- and long-term ground-based observations to refine estimates of the orbits and physical properties of NEOs, which helps to assess the risk they might pose to Earth.

B612’s Sentinel Telescope to Scan Heavens for Earth Crossing Asteroids

SAN FRANCISCO, CA (B612 PR) – In a press conference at the California Academy of Sciences Thursday morning, the B612 Foundation unveiled its plans to build, launch, and operate the first privately funded deep space mission – SENTINEL – a space telescope to be placed in orbit around the Sun, ranging up to 170 million miles from Earth, for a mission of discovery and mapping. The Foundation leadership and technical team include some of the most experienced professionals in the world to lead this effort.
