'World Space Week' blasts off

A weeklong international celebration of spaceflight and exploration kicks off Thursday, with hundreds of events planned in dozens of countries around the world.

The 13th annual World Space Week runs from Oct. 4 through Oct. 10 ? both key dates in the history of space exploration. On Oct. 4, 1957, the Soviet Union lofted Sputnik 1, humanity's first-ever artificial satellite. And the Outer Space Treaty, which forms the basis for international space law, came into effect on Oct. 10, 1967.

World Space Week always has a theme, and this year it's "Space for Human Safety and Security." More than 350 events spread across nearly 50 countries will highlight the ways in which humanity's space activities make daily life better for us here on Earth, organizers said.

The events cover a lot of ground, both literally and figuratively. They include an astrophotography exhibition in New Delhi, India, for example, as well as a presentation by NASA astronaut Mike Foreman in Cleveland, Ohio, about NASA's commercial crew program.

And today, World Space Week will hold a tweetup from the International Astronautical Congress meeting in Naples, Italy. The event, which uses the hashtag #wswtweetup, begins at 12 p.m. EDT. Apollo moonwalker Buzz Aldrin is slated to speak, as is Planetary Society CEO and former TV "Science Guy" Bill Nye. [Sputnik 1, Earth's First Artificial Satellite (Photos)]

The United Nations established World Space Week in 1999, and the event was first held a year later. The U.N. continues to help organize the annual celebration, according to the World Space Week Association.

World Space Week has five main goals, according to its website: 1) Educate people around the globe about the benefits of spaceflight and exploration; 2) Encourage greater use of space for sustainable economic development; 3) Show that space programs enjoy public support; 4) Get young people excited about science; and 5) Encourage international cooperation in space outreach and education.
