Millennium: 3rd millennium

The 2020s (pronounced "twenty-twenties") is the next decade in the Gregorian Calendar. It will begin on January 1, 2020 and will end on December 31, 2029.

A decade is a period of 10 years. The word is derived from the Ancient Greek: δεκάς, romanized: dekas), which means a group of ten. Other words for spans of years also come from Latin: biennium, triennium, quadrennium, lustrum, century, millennium.


Notable predictions and known events

Sir John Royden Maddox, FRS was a British biologist and science writer. He was an editor of Nature for 22 years, from 1966 to 1973 and 1980 to 1995.

<i>Nature</i> (journal) British multidisciplinary scientific journal

Nature is a British multidisciplinary scientific journal, first published on 4 November 1869. It is one of the most recognizable scientific journals in the world, and was ranked the world's most cited scientific journal by the Science Edition of the 2010 Journal Citation Reports and is ascribed an impact factor of 40.137, making it one of the world's top academic journals. It is one of the few remaining academic journals that publishes original research across a wide range of scientific fields.

Global warming rise in the average temperature of the Earths climate system and its related effects

Global warming is a long-term rise in the average temperature of the Earth's climate system, an aspect of climate change shown by temperature measurements and by multiple effects of the warming. Though earlier geological periods also experienced episodes of warming, the term commonly refers to the observed and continuing increase in average air and ocean temperatures since 1900 caused mainly by emissions of greenhouse gases in the modern industrial economy. In the modern context the terms global warming and climate change are commonly used interchangeably, but climate change includes both global warming and its effects, such as changes to precipitation and impacts that differ by region. Many of the observed changes in climate since the 1950s are unprecedented in the instrumental temperature record, and in historical and paleoclimate proxy records of climate change over thousands to millions of years.

Space exploration Discovery and exploration of outer space

Space exploration is the discovery and exploration of celestial structures in outer space by means of evolving and growing space technology. While the study of space is carried out mainly by astronomers with telescopes, the physical exploration of space is conducted both by unmanned robotic space probes and human spaceflight.

Spacecraft manned vehicle or unmanned machine designed to fly in outer space

A spacecraft is a vehicle or machine designed to fly in outer space. Spacecraft are used for a variety of purposes, including communications, Earth observation, meteorology, navigation, space colonization, planetary exploration, and transportation of humans and cargo. All spacecraft except single-stage-to-orbit vehicles cannot get into space on their own, and require a launch vehicle.

2020 (MMXX) will be a leap year starting on Wednesday of the Gregorian calendar, the 2020th year of the Common Era (CE) and Anno Domini (AD) designations, the 20th year of the 3rd millennium, the 20th year of the 21st century, and the 1st year of the 2020s decade.

2025 (MMXXV) will be a common year starting on Wednesday of the Gregorian calendar, the 2025th year of the Common Era (CE) and Anno Domini (AD) designations, the 25th year of the 3rd millennium, the 25th year of the 21st century, and the 6th year of the 2020s decade.

Lander (spacecraft) spacecraft which descends toward and comes to rest on the surface of an astronomical body

A lander is a spacecraft which descends toward and comes to rest on the surface of an astronomical body. By contrast with an impact probe, which makes a hard landing and is damaged or destroyed so ceases to function after reaching the surface, a lander makes a soft landing after which the probe remains functional.

History of spaceflight aspect of history

Spaceflight began in the 20th century following theoretical and practical breakthroughs by Konstantin Tsiolkovsky and Robert H. Goddard. The Soviet Union took the lead in the post-war Space Race, launching the first satellite, the first man and the first woman into orbit. The United States caught up with, and then passed, their Soviet rivals during the mid-1960s, landing the first man on the Moon in 1969. In the same period, France, the United Kingdom, Japan and China were concurrently developing more limited launch capabilities.

The Indian Human Spaceflight Programme (HSP) was created in 2007 by the Indian Space Research Organisation (ISRO) to develop the technology needed to launch crewed orbital spacecraft into low Earth orbit. The first crewed flight is planned with a spacecraft called Gaganyaan for December 2021 on a home-grown GSLV Mk-III rocket.

Atlantic multidecadal oscillation

The Atlantic Multidecadal Oscillation (AMO) is a climate cycle that affects the sea surface temperature (SST) of the North Atlantic Ocean based on different modes on multidecadal timescales. While there is some support for this mode in models and in historical observations, controversy exists with regard to its amplitude, and in particular, the attribution of sea surface temperature change to natural or anthropogenic causes, especially in tropical Atlantic areas important for hurricane development. The Atlantic multidecadal oscillation is also connected with shifts in hurricane activity, rainfall patterns and intensity, and changes in fish populations.

Space probe unmanned robotic spacecraft that does not orbit the Earth, but, instead, explores further into outer space

A space probe is a robotic spacecraft that does not orbit Earth, but instead, explores further into outer space. A space probe may approach the Moon; travel through interplanetary space; flyby, orbit, or land on other planetary bodies; or enter interstellar space.

Exploration of Uranus

The exploration of Uranus has, to date, been solely through telescopes and NASA's Voyager 2 spacecraft, which made its closest approach to Uranus on January 24, 1986. Voyager 2 discovered 10 moons, studied the planet's cold atmosphere, and examined its ring system, discovering two new rings. It also imaged Uranus' five large moons, revealing that their surfaces are covered with impact craters and canyons.

Human mission to Mars putting humans on the planet Mars

A human mission to Mars has been the subject of science fiction, aerospace engineering, and scientific proposals since the 19th century. The plans comprise proposals to land on Mars, eventually settling on and terraforming the planet, while utilizing its moons, Phobos and Deimos.

Several Asian countries have space programs and are actively competing to achieve scientific and technological advancements in space, a situation sometimes referred to as the Asian space race in the popular media as a reference to the earlier Space Race between the United States and the Soviet Union. Like the previous space race, issues involved in the current push to space include national security, which has spurred many countries to send artificial satellites as well as humans into Earth orbit and beyond. A number of Asian countries are seen as contenders in the ongoing race to be the pre-eminent power in space.

NASA space-related agency of the United States government

The National Aeronautics and Space Administration is an independent agency of the United States Federal Government responsible for the civilian space program, as well as aeronautics and aerospace research.

The future of space exploration involves both telescopic exploration and the physical exploration of space by unmanned robotic space probes and human spaceflight.
