Millennium: 3rd millennium

The 2030s (pronounced "twenty-thirties") is a decade of the Gregorian calendar that will begin on January 1, 2030 and will end on December 31, 2039.

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

The Gregorian calendar is the most widely used civil calendar in the world. It is named after Pope Gregory XIII, who introduced it in October 1582. The calendar spaces leap years to make the average year 365.2425 days long, approximating the 365.2422-day tropical year that is determined by the Earth's revolution around the Sun. The rule for leap years is:

Every year that is exactly divisible by four is a leap year, except for years that are exactly divisible by 100, but these centurial years are leap years if they are exactly divisible by 400. For example, the years 1700, 1800, and 1900 are not leap years, but the year 2000 is.

Literacy ability to read for knowledge, write coherently, and think critically about the written word; ability to read, write, and use arithmetic

Dictionaries traditionally define literacy as the ability to read and write. In the modern world, this is one way of interpreting literacy. One more broad interpretation sees literacy as knowledge and competence in a specific area. The concept of literacy has evolved in meaning. The modern term's meaning has been expanded to include the ability to use language, numbers, images, computers, and other basic means to understand, communicate, gain useful knowledge, solve mathematical problems and use the dominant symbol systems of a culture. The concept of literacy is expanding across OECD countries to include skills to access knowledge through technology and ability to assess complex contexts. A person who travels and resides in a foreign country but is unable to read or write in the language of the host country would be regarded by the locals as illiterate.

Exploration of Mars Mars scientific exploration programs

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 met with unexpected success, such as the twin Mars Exploration Rovers, which operated for years beyond their specification.

2050 (MML) will be a common year starting on Saturday of the Gregorian calendar, the 2050th year of the Common Era (CE) and Anno Domini (AD) designations, the 50th year of the 3rd millennium, the 50th year of the 21st century, and the 1st year of the 2050s decade.

Colonization of Mars Scientific study on human colonization on Mars

Mars is the focus of much scientific study about possible human colonization. Mars's surface conditions and past presence of liquid water make it arguably the most hospitable planet in the Solar System besides Earth. Mars requires less energy per unit mass (delta-v) to reach from Earth than any planet, other than Venus.

Exploration of the Moon various missions to the Moon

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.

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.

World population The total number of living humans on Earth

In demographics, the world population is the total number of humans currently living, and was estimated to have reached 7.6 billion people as of May 2018. It took over 200,000 years of human history for the world's population to reach 1 billion; and only 200 years more to reach 7 billion.

In contemporary history, the third millennium is a period of time that began on January 1, 2001, and will end on December 31, 3000 of the Gregorian calendar. It is distinct from the millennium known as the 2000s which began on January 1, 2000 and will end on December 31, 2999.

Mars to Stay Mars exploration mission type pushing for the installation of a permanent colony

Mars to Stay missions propose astronauts sent to Mars for the first time should intend to stay. Unused emergency return vehicles would be recycled into settlement construction as soon as the habitability of Mars becomes evident to the initial pioneers. Mars to Stay missions are advocated both to reduce cost and to ensure permanent settlement of Mars. Among many notable Mars to Stay advocates, former Apollo astronaut Buzz Aldrin has been particularly outspoken, suggesting in numerous forums "Forget the Moon, Let’s Head to Mars!" and, in June 2013, Aldrin promoted a manned mission "to homestead Mars and become a two-planet species". In August 2015, Aldrin, in association with the Florida Institute of Technology, presented a "master plan", for NASA consideration, for astronauts, with a "tour of duty of ten years", to colonize Mars before the year 2040. The Mars Underground, Mars Homestead Foundation, Mars One, and Mars Artists Community advocacy groups and business organizations have also adopted Mars to Stay policy initiatives.

Space policy of the Barack Obama administration

The space policy of the Barack Obama administration was announced by U.S. President Barack Obama on April 15, 2010, at a major space policy speech at Kennedy Space Center. He committed to increasing NASA funding by $6 billion over five years and completing the design of a new heavy-lift launch vehicle by 2015 and to begin construction thereafter. He also predicted a U.S.-crewed orbital Mars mission by the mid-2030s, preceded by an asteroid mission by 2025. In response to concerns over job losses, Obama promised a $40 million effort to help Space Coast workers affected by the cancellation of the Space Shuttle program and Constellation program.

Space Launch System American Space Shuttle-derived heavy expendable launch vehicle

The Space Launch System (SLS) is an American Space Shuttle-derived super heavy-lift expendable launch vehicle. It is part of NASA's deep space exploration plans including a crewed mission to Mars. SLS follows the cancellation of the Constellation program, and is to replace the retired Space Shuttle. The NASA Authorization Act of 2010 envisions the transformation of the Constellation program's Ares I and Ares V vehicle designs into a single launch vehicle usable for both crew and cargo, similar to the Ares IV concept. The SLS is to be the most powerful rocket in existence with a total thrust greater than that of the Saturn V, although Saturn V could carry a greater payload mass.

Asteroid Redirect Mission United States space mission to collect samples from an asteroid

The Asteroid Redirect Mission (ARM), also known as the Asteroid Retrieval and Utilization (ARU) mission and the Asteroid Initiative, was a space mission proposed by NASA in 2013. The Asteroid Retrieval Robotic Mission (ARRM) spacecraft would rendezvous with a large near-Earth asteroid and use robotic arms with anchoring grippers to retrieve a 4-meter boulder from the asteroid.

NASA's new Space Launch System (SLS) and Orion programs will allow for beyond low-Earth orbit (LEO) spaceflight. There are a number of notional, proposed missions for the programs, none of which are confirmed. Some of these mission concepts include:
