A number of significant scientific events occurred in 2013, including the discovery of numerous Earthlike exoplanets, the development of viable lab-grown ears, teeth, livers and blood vessels, and the atmospheric entry of the most destructive meteor since 1908. The year also saw successful new treatments for diseases such as HIV, Usher syndrome and leukodystrophy, and a major expansion in the use and capabilities of technologies such as 3D printing and autonomous cars.
The United Nations designated 2013 the International Year of Water Cooperation. [1]
Astrobiology, is a scientific field within the life and environmental sciences that studies the origins, early evolution, distribution, and future of life in the universe by investigating its deterministic conditions and contingent events. As a discipline, astrobiology is founded on the premise that life may exist beyond Earth.
The possibility of life on Mars is a subject of interest in astrobiology due to the planet's proximity and similarities to Earth. To date, no conclusive evidence of past or present life has been found on Mars. Cumulative evidence suggests that during the ancient Noachian time period, the surface environment of Mars had liquid water and may have been habitable for microorganisms, but habitable conditions do not necessarily indicate life.
The colonization of Mars is the proposed process of establishing and maintaining control of Martian land for exploitation and the possible settlement of Mars. Most colonization concepts focus on settling, but colonization is a broader ethical concept, which international space law has limited, and national space programs have avoided, focusing on a human mission to Mars to explore the planet. Settlement of Mars would involve migration of humans to the planet, the establishment of long-term human presence, and the exploitation of local resources. Though uncrewed rovers have explored Mars, there have been no crewed missions and there have been no return missions.
The year 2008 involved numerous significant scientific events and discoveries, some of which are listed below.
Extraterrestrial liquid water is water in its liquid state that naturally occurs outside Earth. It is a subject of wide interest because it is recognized as one of the key prerequisites for life as we know it and is thus surmised to be essential for extraterrestrial life.
Health threats from cosmic rays are the dangers posed by cosmic rays to astronauts on interplanetary missions or any missions that venture through the Van-Allen Belts or outside the Earth's magnetosphere. They are one of the greatest barriers standing in the way of plans for interplanetary travel by crewed spacecraft, but space radiation health risks also occur for missions in low Earth orbit such as the International Space Station (ISS).
Mars is the fourth planet from the Sun. The surface of Mars is orange-red because it is covered in iron(III) oxide dust, giving it the nickname "the Red Planet". Mars is among the brightest objects in Earth's sky, and its high-contrast albedo features have made it a common subject for telescope viewing. It is classified as a terrestrial planet and is the second smallest of the Solar System's planets with a diameter of 6,779 km (4,212 mi). In terms of orbital motion, a Martian solar day (sol) is equal to 24.5 hours, and a Martian solar year is equal to 1.88 Earth years. Mars has two natural satellites that are small and irregular in shape: Phobos and Deimos.
The National Aeronautics and Space Administration is an independent agency of the U.S. federal government responsible for the civil space program, aeronautics research, and space research. Established in 1958, it succeeded the National Advisory Committee for Aeronautics (NACA) to give the U.S. space development effort a distinct civilian orientation, emphasizing peaceful applications in space science. It has since led most of America's space exploration programs, including Project Mercury, Project Gemini, the 1968–1972 Apollo Moon landing missions, the Skylab space station, and the Space Shuttle. Currently, NASA supports the International Space Station (ISS) along with the Commercial Crew Program, and oversees the development of the Orion spacecraft and the Space Launch System for the lunar Artemis program.
The year 2010 involved numerous significant scientific events and discoveries, some of which are listed below. The United Nations declared 2010 the International Year of Biodiversity.
The year 2011 involved many significant scientific events, including the first artificial organ transplant, the launch of China's first space station and the growth of the world population to seven billion. The year saw a total of 78 successful orbital spaceflights, as well as numerous advances in fields such as electronics, medicine, genetics, climatology and robotics.
The year 2012 involved many significant scientific events and discoveries, including the first orbital rendezvous by a commercial spacecraft, the discovery of a particle highly similar to the long-sought Higgs boson, and the near-eradication of guinea worm disease. A total of 72 successful orbital spaceflights occurred in 2012, and the year also saw numerous developments in fields such as robotics, 3D printing, stem cell research and genetics. Over 540,000 technological patent applications were made in the United States alone in 2012.
The Mars Science Laboratory and its rover, Curiosity, were launched from Earth on 26 November 2011. As of September 6, 2024, Curiosity has been on the planet Mars for 4296 sols since landing on 6 August 2012. (See Current status.)
A number of significant scientific events occurred in 2014, including the first robotic landing on a comet and the first complete stem-cell-assisted recovery from paraplegia. The year also saw a significant expansion in the worldwide use and sophistication of technologies such as unmanned aerial vehicles and wearable electronics.
A number of significant scientific events occurred in 2015. Gene editing based on CRISPR got significantly improved. A new human-like species, Homo naledi, was first described. Gravitational waves were observed for the first time, and dwarf planets Pluto and Ceres were visited by spacecraft for the first time. The United Nations declared 2015 the International Year of Soils and Light-based Technologies.
A number of significant scientific events occurred in 2016. The United Nations declared 2016 the International Year of Pulses.
A number of significant scientific events occurred in 2017. The United Nations declared 2017 the International Year of Sustainable Tourism for Development.
A number of significant scientific events occurred in 2018.
A number of significant scientific events occurred in 2019.
