Simple schematic representation of the mutilation of the Tree of life because of generic extinctions and extinction risks. The bottom half of the tree depicted as dead branches shows examples of the extinct genera, and the upper half shows examples of genera at risk of extinction. Extinct genera: (I) lower row left - Delcourt’s giant gecko (Hoplodactylus, left), of which the only specimens known were found in a museum without a label, but probably they were found in New Zealand; and saddle-backed Rodrigues giant tortoise (Cylindraspis, right) from Rodrigues Island in the Indian Ocean. Lower row right - Yunnan Lake newt (Cynops, left) from China; and the gastric brooding frogs (Rheobatrachus, right) from rainforests in Queensland, Australia. (II) Second bottom-up row left - thylacine (Thylacinus, left), the largest carnivorous marsupial, last known from Tasmania; and Yangtze River dolphin or baijii (Lipotes, right) from China, one of very few freshwater dolphins. Second bottom-up row right - elephant birds (Aepyornis, left), the largest birds surviving to modern times, represent also both an extinct genus and family (Aepyornithidae) endemic to Madagascar; and Moho birds (genus Moho, right) represent also both an extinct genus and family (Mohidae) from Hawaii. Endangered genera: (III) Third bottom-up row left - King cobra (Ophiophagus, left) from Asia; and gavial (Gavialis, right) from India and Nepal. Third bottom-up row right - Alpine newt (Ichthyosaura, left) from Europe; and Mahogany frog (Abavorana, right) from the Malay Peninsula. (IV) Upper row left: volcano rabbit (Romerolagus, left) known from few mountains close to Mexico City, and elephant (Loxodonta, right) from Africa. Upper row right - ‘i’iwi or scarlet honeycreeper (Drepanis, left) from Hawaii; and kakapo (Strigops, right) a flightless parrot from New Zealand. Image credit: Marco Antonio Pineda.

The NASA UAP independent study team recommends that NASA plays a prominent role in the whole-of-government effort to understand UAP by leveraging its extensive expertise to contribute to a comprehensive, evidence-based approach that is rooted in the scientific method. The team members specifically recommend that NASA utilize its existing and planned Earth-observing assets to probe the local environmental conditions associated with UAP that are initially detected by other means. In so doing, NASA can directly probe whether certain environmental factors are coincident with known UAP. They further recommend that NASA explore enhancing collaborations with the U.S. commercial remote-sensing industry, which offer powerful constellations of high-resolution Earth-observing satellites.
