The examination of the outer solar system can be increased by Vera Rubin Observatory (VRO). When this gigantic telescope later opens its eye in 2025, it begins a decades of overview of the constantly changing sky. As part of this time-lapse vision of the cosmos, distant objects in the Kuiper belt are among the most difficult destinations.
A team of planetary scientists under the direction of JJ Kavelaars of the Canadian Research Center Herzberg Astronomy and Astrophysics suggests using VRO for a deep overview of objects along the trajectory of the New Horizon spacecring. There are currently about 61 astronomical units from Earth and is the only spaceship that exceeds the Kuiper belt. This “deep bore” micro survey will use in six 5-hour visits to about 30 hours of ruby time in six years. It starts in 2026 and should determine the orbits for around 700 Kuiper belt objects (KBOS).
According to Kavelaars, the team needs at least five hours a night in two nights so that its survey is successful. “More nights in the same area (to construct orbital arches of the recognized sources) is likely to become more valuable than deeper,” he said.
Opportunities for new horizon goals
The team's proposal quotes earlier discoveries of objects in the Kuiper belt by Kavelaar's colleague Wesley Fraser. In 2024, Fraser and his team reported on the recognition of 239 Transneptunic objects. Her work was part of a new Horizons survey for remote smaller bodies. These detections came via the Hyper Suprime cam mosaic image on the Subaru telescope. The Fraser team identified an abundance of very weak objects in distances of more than 70 au from the sun. How they are confirmed explains this extended number of objects some excellent occults and other readings that the student made dust switch on board the New Horizon spacecraft.

The deep survey with Rubin should uncover objects so that new horizons can study in the distance. According to Kavelaar, objects near Flyby will probably be much less common. “We will be very lucky if it turns out that one of the spaceships is so close enough that we can steer the spaceship on him,” he said, “but we will at least get a solid sample of objects to watch new horizons in longer ranges.”
It would be cool if the survey finds another contact binary like Arrokoth. New Horizons flew past the 2019. Most will probably not be close enough for a flyby or even distant observations of the spacecraft. However, their detection is sufficient to inform the planetary scientists that the Kuiper belt is richer in population than the current population models of the outer solar system.
Goals in the Kuiper girdle Graben
The measurement of Vera Rubin Observatory (LIST) by the inheritance of the room and the time (LSS), which is the main task of the observatory, will take place a number of 30-second field images of 9.6 square meters using the LSSCAM field installed on 8.36 m simonyi survey telescope. These observations will switch between different filter straps to get all the details and a “deep look” in the sky. This pace of Deep Sky imaging will repeat from a mountain summit in Chile for ten years. The builders suggest that the results of this survey will offer the greatest astronomical film ever.

In the team's proposal paper for the “piggyback” about the primary observations, it says that “the currently planned cadence is (see PSTN-056) will enable the discovery of an unprecedented number of small solar system bodies, including trans-neptunic objects (TNOS), precise circulation bits and physical properties that the factors that the factors that the factors Factors that are the factors that are currently more artificial factors than the factors that have the factors that are currently known to the factors that are currently known.
The 30-hour wishes for the micro check of the Kuiper belt should be enough to determine KBO positions and tracks. This enables possible observations of new horizons (if not even a flyby) and also with future spaceships.
“A very exciting option is that we will carry out this very deep search with Rubin and confirm the population that Fraser has reported and characterize their orbital distribution,” he said. “Then we were able to design a search for success with these more detailed information (if no Flyby was found in the ruby search), which is to be carried out with the Roman observatory when starting.”
