The target satellite orbited between 850 km (530 mi) and 882 km (548 mi), the portion of near-Earth space most densely populated with satellites. [98] Since atmospheric drag is low at that altitude, the debris is slow to return to Earth, and in June 2007 NASA's Terra environmental spacecraft maneuvered to avoid impact from the debris. [99]
In early 2022, the European Investment Bank published the results of its 2021–2022 Climate Survey, showing that 52% of Europeans under 30, 37% of people between 30 and 64 and 25% for people aged 65 and above plan to travel by air for their summer holidays in 2022; and 27% of those under 30, 17% for people aged 30–64 and 12% for people aged ...

The health and environmental impact of transport is significant because transport burns most of the world's petroleum.This causes illness and deaths from air pollution, including nitrous oxides and particulates, and is a significant cause of climate change through emission of carbon dioxide.
From climate change to species loss and pollution, humans have etched their impact on the Earth with such strength and permanence since the middle of the 20th century that a special team of ...
Passage through the solar system could result in the destruction of the Earth or the Sun by being directly consumed. Astronomers expect the collision of the Milky Way Galaxy with the Andromeda Galaxy in about four billion years, but due to the large amount of empty space between them, most stars are not expected to collide directly.

Stephen Hawking is a supporter of space travel, in part, because he thinks the survival of humanity depends on it. Hawking shared these thoughts in an afterword for Julian Guthrie's book "How to ...
