Wikipedia Online Encyclopedia Launches

Jimmy Wales and Larry Sanger had launched Nupedia in 2000 as a peer-reviewed free online encyclopedia, but progress was slow due to its rigorous expert review process. On January 15, 2001, they introduced Wikipedia as a complementary wiki-based project allowing anyone to edit articles rapidly. The site went live under the wikipedia.com domain with an initial focus on building content collaboratively, drawing inspiration from open-source software principles. Early policies emphasized neutral point of view and community governance, quickly attracting contributors beyond the small Nupedia team. Within months, Wikipedia expanded to multiple languages and surpassed Nupedia in scale, eventually leading to the latter's closure in 2003.

First Draft of Human Genome Sequence Published

The Human Genome Project, an international effort involving thousands of scientists across multiple countries, aimed to map the roughly 3 billion base pairs of human DNA. On February 15, 2001, the journal Nature published the initial sequencing and analysis of the working draft, covering over 90 percent of the genome with gaps still remaining. A companion paper appeared in Science the following day. The achievement built on advances in sequencing technology and collaborative data sharing. It provided a foundational reference for understanding genetic variation and disease.

Russian Space Station Mir Deorbited into Pacific

Mir, launched in 1986, served as a long-duration orbital laboratory hosting international crews and advancing microgravity research for 15 years. Russia faced funding constraints and shifted priorities to the International Space Station. On March 23, 2001, after docking Progress M1-5, controllers executed a series of burns to lower the orbit. The station reentered the atmosphere over the South Pacific near Fiji, with most debris burning up safely. Fragments splashed down harmlessly, ending Mir's mission.

Al-Qaeda Launches Coordinated Attacks on U.S.

Nineteen hijackers affiliated with al-Qaeda seized four commercial airliners departing East Coast airports. Two struck the World Trade Center towers in New York, causing their collapse and killing nearly 3,000 people total. A third plane hit the Pentagon in Virginia, while passengers on the fourth overpowered the hijackers, forcing the aircraft down in a Pennsylvania field. The coordinated strikes represented the deadliest terrorist attack in history and the first major foreign assault on the U.S. mainland since 1812.

U.S.-Led Strikes Begin in Afghanistan

After the September 11, 2001, terrorist attacks by al-Qaeda, the United States demanded that Afghanistan's Taliban regime hand over Osama bin Laden and dismantle terrorist networks. The Taliban refused, prompting a military response as part of the broader Global War on Terror. On October 7, 2001, U.S. and British forces launched Operation Enduring Freedom with airstrikes on Taliban and al-Qaeda targets across Afghanistan, supported by naval assets and later ground operations with coalition partners and Northern Alliance forces. The initial strikes targeted command centers, air defenses, and training camps. Within weeks, the Taliban government collapsed in major cities, though fighting continued. The campaign marked the start of America's longest war.
