The next-generation asteroid hunter for NASA has started to take shape.

NASA’s Located Close Object Surveyor (NEO Surveyor), a space observatory designed to search for the most difficult-to-find comets and asteroids that enter its orbit, has passed a rigorous and programmatic evaluation.The next-generation asteroid hunter for NASA has started.

The mission is currently entering the final design and manufacturing phases and creating the baseline for its technical, financial, and timeframe requirements. The mission furthers the goals of NASA Headquarters at Washington’s Planetary Defense Coordinators (PDCO).

In the event that they strike the Earth, asteroids of this size have the potential to cause severe regional devastation, if not worse. According to Lindley Johnson, NASA’s Space Based Officer at PDCO, “NEO Surveyor is the next generation of NASA’s capacity to rapidly identify, track, and analyze potentially dangerous near-Earth objects.”

Although a space-base infrare telescope is the ultimate high ground that would allow NASA’s planetary defense strategy, ground-base telescopes are still crucial for us to continuously monitor the skies.

Locate them first:

The L1 Lagrange point, a zone of gravitational stability beyond the Earth and the Sun, is where the NEO Surveyor will orbit for its five-year main mission after traveling 1,000 miles. The Jet Propulsion Laboratory of NASA is located in Southern California and is in charge of NEO Surveyor.

The NEO Explorer will observe the solar system from this position using infrared light, which is not visible to the naked eye. Larger floor observatories may miss relatively close objects that this space telescope can see by employing its small light-collecting aperture of almost 20 inches since those wavelengths are primarily block by the upper orbit (50 centimeters).

Earth objects:

The most difficult-to-find near-Earth objects, such as black asteroids and comets that don’t return much visible light, may be track using NEO Surveyor’s cutting-edge detectors, which are built to observe two high-ttemperature infrarebands. These objects are lit because sunlight has heat them, and the NEO Sensor is sensitive to infrare light.


NEO Surveyor will also be able to locate Earth Trojan asteroids, which are meteorites that visit Earth from the direction of the sun, in addition to those that lead and tail our planet’s orbit.

According to Amy Mainzer, this mission’s survey coordinator at the Arizona State University in Tucson, “for the first time in our history of the earth, Earthlings are creating strategies to defend Earth by diverting harmful asteroids.” “However, we must first locate them in order to deflect them.” NEO Survey will be a game changer in that endeavor.”

The project will also contribute to the characterization of near-Earth object composition, shape, spin, and orbit. The mission’s main objective is planetary defense, but the data may also be utilize to learn more about the beginnings and development of comets and asteroids, which are the oldest constituents of our universe.

When NEO Surveyor is release, it will build on the accomplishments of its predecessor, the Locate Close Object Broad Infrare Survey Explorer (NEOWISE).

NEO Surveyor was the first satellite project designe exclusively to identify significant quantities of these potentially dangerous asteroids and comets. NEOWISE was repurpose from the WISE space observatory after that mission concluded in 2011.

Already in progress

On Nov. 29, the mission reached this milestone, and work on developing essential instruments began. For instance, the substantial radiators that will enable passive cooling of the system are now being construct. The instrument’s infrared thermal sensor must operate at far lower temperatures than the spacecraft’s electronics in order to pick up the little infrared illumination of asteroids and comets. That crucial function will be carry out by the radiators, negating the need for elaborate active cooling systems.

In addition, work has started on the composite struts that will keep the telescope’s equipment apart from the ship. The sunshield will filter sunlight that may otherwise obstruct the Hubble Space Telescope’s view of close objects and not heat up the instrument, while the struts will keep the cold instrument apart from the heated ship and sunshield.

The instrument’s infrared thermal, fiber optics, filters, electronics, and casing have all made progress. Additionally, work has started on the mirror for the space telescope, which will be mold using a specially made diamond-turning machine from a solid piece of aluminum.

Tom Hoffman, the project manager for JPL’s NEO Surveyor, said, “The development team, including all of its institutional and industry colleagues, is already extremely busy developing and producing components that will eventually become flight hardware.” We’re thrille to be operating on this special space telescope as the program enters this new period and are already anticipating our launch and the beginning of our significant mission.
