The AARO was established in July 2022 and is responsible for tracking objects in the sky, underwater and in space – or possibly an object that has the ability to move from one domain to the next.
Congress tasked NASA to find 90% of all objects near Earth that are larger than 140 meters in 2005, which resulted in Pan-STARRS telescopes, according to the report.
On October 19, 2017, the Pan-STARRS detected an unusual interstellar object that was later named ‘Oumuamua, or scout in Hawaiian. The object was cigar-shaped, appeared flat, and was propelled away from the sun without showing a cometary tail, leading scientists to believe it was artificial.NASA was given a task by Congress to find 90% of all objects near Earth that are larger than 140 meters in 2005.Three years later, another object was discovered, the report noted, namely NASA’s rocket booster 2020 SO, which had no cometary trail.
The report also said six months before ‘Oumuamua made its closest approach to Earth, a meter-sized interstellar meteor, IM2, crashed on earth and exhibited an identical speed relative to the Sun at large distances and an identical shape to ‘Oumuamua. “With proper design, these tiny probes would reach the Earth or other solar system planets for exploration, as the parent craft passes by within a fraction of the Earth-Sun separation — just like ‘Oumuamua’ did,” the authors wrote. “Astronomers would not be able to notice the spray of mini probes because they do not reflect enough sunlight for existing survey telescopes to notice them.

Frontiers | Pancosmorio (world limit) theory of the sustainability of human migration and settlement in spaceIt seems to be an accepted assumption that human migration into space is inevitable. Humans are a species of Earth. We are connected to Earth through evolution. We are also connected to space; our bodies contain heavy elements generated by fusion in the cores of stars. What does this evolutionary connection of humans to a star and a planet mean for their ability to inhabit space? This paper combines 100 years of research and scientific development of a theory of ecological thermodynamics with classical mechanics theory and analytical models of self-restoring heat engines to explain how the Sun and Earth have evolved into islands of order in the entropy of space. An explanation is provided regarding how naturally occurring conservative force fields engage a diversity of natural resources in semi-reversible cycles that build a high-exergy ecosphere. The science and evidence suggest that the ability to establish a human settlement in space without the self-restoring order, capacity, and organization of Earth will ultimately lead to settlement failure. Supply chains would disappear, market resources would be depleted, advancement in human pursuits would be disrupted, social and governance systems would falter or collapse, human population numbers would decline, genetic diversity in the human genome would be lost, average human individual biomass would decrease, and human knowledge and understanding would be forgotten. What does it mean to have a location in space outside of Earth be “like Earth?” The results of research are presented as a pancosmorio theory of human sustainability that is developed using the scientific philosophy methodology of abductive reasoning. Four analytical models of space ecosphere sustainability and five hypotheses with proposed tests for falsifiability are provided, including a theorem that suggests a limit to human expansion into space. A new quantitative method of human sustainability is developed from theories of network ecology, providing
