This article is a summary of the 2010s in science and technology.
Big data and "Big Tech" saw an expansion in size and power in the 2010s, particularly FAANG corporations. The growing influence of "Big Tech" over cyberspace drew scrutiny and increased oversight from national governments. The G20 countries began closing tax loopholes [1] and the European Union began asserting legal guidelines over domains such as data privacy, copyright, and hate speech, the latter of which helped fuel a debate over tech censorship and free speech online, particularly deplatforming. Throughout the decade, the United States government increasingly scrutinized the tech industry, from attempted copyright regulations to threatening antitrust probes. [2] [3] Increased protectionism and attempts to regulate and localize the internet by national governments also raised fears of cyber-balkanization in the later half of the decade. [4] [5] [6]
Spaceflight became increasingly privatized, including crewed spaceflight. SpaceX captures a significant share of the commercial launch market with Falcon 9. [56] [57] Falcon 9 became the first rocket to land its booster propulsively for reuse, in 2019 most flights reused boosters. Several other companies started working on partially reusable rockets while SpaceX started development of a fully reusable rocket, Starship. Towards the end of the decade around 100 companies were developing rockets for the small satellite market, [58] some have made test flights and Rocketlab's Electron made multiple commercial flights. [59] The Space Shuttle was retired in 2011. SpaceX and Boeing developed commercial crewed spacecraft for orbital flights (SpaceX Dragon 2, Starliner), Dragon 2 made its first crewed flights in 2020. Blue Origin develops the crewed New Shepard for suborbital flights. Virgin Galactic develops a spacecraft for suborbital flights and performs first crewed flights. NASA Dawn probe was the first spacecraft to orbit two extraterrestrial bodies, [60] the first spacecraft to visit either Vesta or Ceres, and the first to orbit a dwarf planet, [61] arriving at Ceres in March 2015, a few months before New Horizons flew by Pluto in July 2015.
Other notable developments in astronomy and spaceflight over the decade included:
Jet Propulsion Laboratory (JPL) is a federally funded research and development center in Pasadena, California, United States. Founded in 1936 by Caltech researchers, the laboratory is now owned and sponsored by the National Aeronautics and Space Administration (NASA) and administered and managed by the California Institute of Technology.
Space exploration is the use of astronomy and space technology to explore outer space. While the exploration of space is currently carried out mainly by astronomers with telescopes, its physical exploration is conducted both by uncrewed robotic space probes and human spaceflight. Space exploration, like its classical form astronomy, is one of the main sources for space science.
A lander is a spacecraft that descends towards, then comes to rest on the surface of an astronomical body other than Earth. In contrast to an impact probe, which makes a hard landing that damages or destroys the probe upon reaching the surface, a lander makes a soft landing after which the probe remains functional.
The planet Mars has been explored remotely by spacecraft. Probes sent from Earth, beginning in the late 20th century, have yielded a large increase in knowledge about the Martian system, focused primarily on understanding its geology and habitability potential. Engineering interplanetary journeys is complicated and the exploration of Mars has experienced a high failure rate, especially the early attempts. Roughly sixty percent of all spacecraft destined for Mars failed before completing their missions and some failed before their observations could begin. Some missions have been met with unexpected success, such as the twin Mars Exploration Rovers, Spirit and Opportunity, which operated for years beyond their specification.
ExoMars is an astrobiology programme of the European Space Agency (ESA) and the Russian space agency (Roscosmos).
United Launch Alliance, LLC, commonly referred to as ULA, is an American aerospace manufacturer, defense contractor and launch service provider that manufactures and operates a number of rocket vehicles that launch spacecraft into orbits around Earth and other bodies in the Solar System.
The physical exploration of the Moon began when Luna 2, a space probe launched by the Soviet Union, made an impact on the surface of the Moon on September 14, 1959. Prior to that the only available means of exploration had been observation from Earth. The invention of the optical telescope brought about the first leap in the quality of lunar observations. Galileo Galilei is generally credited as the first person to use a telescope for astronomical purposes; having made his own telescope in 1609, the mountains and craters on the lunar surface were among his first observations using it.
Spacecraft electric propulsion is a type of spacecraft propulsion technique that uses electrostatic or electromagnetic fields to accelerate mass to high speed and thus generate thrust to modify the velocity of a spacecraft in orbit. The propulsion system is controlled by power electronics.
Spaceflight began in the 20th century following theoretical and practical breakthroughs by Konstantin Tsiolkovsky, Robert H. Goddard, and Hermann Oberth. First successful large-scale rocket programs were initiated in the 1920s Germany by Fritz von Opel and Max Valier, and eventually in Nazi Germany by Wernher von Braun. 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 men on the Moon in 1969. In the same period, France, the United Kingdom, Japan and China were concurrently developing more limited launch capabilities.
A Mars landing is a landing of a spacecraft on the surface of Mars. Of multiple attempted Mars landings by robotic, uncrewed spacecraft, ten have had successful soft landings. There have also been studies for a possible human mission to Mars, including a landing, but none have been attempted. Soviet Union’s Mars 3, which landed in 1971, was the first successful Mars landing. As of 2023, the Soviet Union, United States and China have conducted Mars landings successfully.
The ExoMars Trace Gas Orbiter is a collaborative project between the European Space Agency (ESA) and the Russian Roscosmos agency that sent an atmospheric research orbiter and the Schiaparelli demonstration lander to Mars in 2016 as part of the European-led ExoMars programme.
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, NASA succeeded the National Advisory Committee for Aeronautics (NACA) to give the U.S. space development effort a distinctly civilian orientation, emphasizing peaceful applications in space science. NASA has since led most American space exploration, including Project Mercury, Project Gemini, the 1968–1972 Apollo Moon landing missions, the Skylab space station, and the Space Shuttle. NASA currently supports the International Space Station and oversees the development of the Orion spacecraft and the Space Launch System for the crewed lunar Artemis program, the Commercial Crew spacecraft, and the planned Lunar Gateway space station.
Several new rockets and spaceports began operations in 2016.
The Emirates Mars Mission is a United Arab Emirates Space Agency uncrewed space exploration mission to Mars. The Hope probe was launched on 19 July 2020, and went into orbit around Mars on 9 February 2021.
Beresheet was a demonstrator of a small robotic lunar lander and lunar probe operated by SpaceIL and Israel Aerospace Industries. Its aims included inspiring youth and promoting careers in science, technology, engineering, and mathematics (STEM), and landing its magnetometer, time capsule, and laser retroreflector on the Moon. The lander's gyroscopes failed on 11 April 2019 causing the main engine to shut off, which resulted in the lander crashing on the Moon. Its final resting position is 32.5956°N, 19.3496°E.
