World Space Week (WSW) 2023

World Space Week 2023 is a global event dedicated to commemorating the achievements of science and technology and their positive impact on humanity.

World Space Week (WSW), which runs from October 4–10 each year, was established by the UN General Assembly in 1999. Throughout the world, science and technology are celebrated during World Space Week for their positive effects on society. It serves as a reminder of the remarkable strides made in the field of space exploration and its benefits for our world.

Why space week is celebrated from Oct 4-10 each year?

It is celebrated on these dates because two significant events occurred on these dates.

  • On October 4, 1957: Orbit exploration was made possible by the launch of Sputnik 1, the first Earth satellite built by humans, into space.
  • On October 10, 1967: The Treaty on the Principles Governing the Activities of States in the Exploration and Use of Outer Space, Including the Moon and Other Celestial Bodies, came into effect.

The theme of world space week 2023

The theme of World Space Week 2023, “Space and Entrepreneurship,” acknowledges the increasing importance of the commercial space sector and the growing opportunities for space-related entrepreneurship. It highlights the new advantages and innovations introduced by space entrepreneurs. The ongoing process of miniaturization and reduced launch costs has made it feasible for small businesses to develop and launch small satellites, as well as for entrepreneurs to create valuable data products for both governmental and industrial use.

World Space Week 2023 aims to inspire students worldwide to pursue studies in STEM (Science, Technology, Engineering, and Mathematics) and business. Additionally, it provides space companies with a platform to recruit the talent necessary for the expanding commercial space industry. The event will also facilitate critical discussions on the transformation of Low Earth Orbit into a more entrepreneurial ecosystem.

The growth of World Space Week underscores the global recognition of this coordinated timeframe for celebrating space-related achievements, motivating students through space-related activities, and promoting space-related programs, policies, and institutions. World Space Week is celebrated by a vast network of over 1,000 space-related organizations, making it the largest network of its kind globally, according to the World Space Week Association (WSWA).

The theme of world space week 2022

The theme of World Space Week 2022 is “Space and Sustainability,” with an emphasis on attaining sustainability from space as well as in space The relationship between space sustainability and human use of space, particularly the orbital zone surrounding the Earth, serves as the inspiration for the theme.

Objectives of World Space Week

  • give special weightage for space outreach and education
  • Inform people everywhere about the advantages that they obtain from space
  • Increase space utilization for sustainable economic development.
  • Explain public support for space programs.
  • Inspire youngsters about math, science, and technology.
  • Promote worldwide cooperation in space outreach and education.

What is space?

Space is everything in the cosmos that is above the level of the Earth’s atmosphere, including the Moon, Mars, other stars, the Milky Way, black holes, and far-off quasars. The pressure in space is incredibly low, and it is practically completely devoid of matter. Because the molecules in space are too far apart for sound to travel between them, sound cannot travel through space.

 The huge distance in space is measured in “light years”. 1 light year is the distance light travelled in a year i.e around 5.8 trillion miles or 9.3 trillion kilometers.

Outer space is typically believed to begin at the Kármán line, which is 100 kilometers (62 miles) above sea level, from our Earth. This is a hypothetical boundary located at an altitude where there isn’t much air to breathe or light to scatter.

How World Space Week is celebrated?

Space agencies, aerospace firms, educational institutions, planetariums, museums, and astronomy clubs all over the world hold space education and outreach activities throughout World Space Week. The public and media pay more attention to these timed space activities.

UNOOSA – UN’s Office for Outer Space Affairs

The United Nations has understood that life in space adds a new dimension to human existence from the beginning of the Space Age. The United Nations Office for Outer Space Affairs (UNOOSA) is the UN department in charge of encouraging global cooperation in space exploration for peaceful purposes. UNOOSA acts as the secretariat for the United Nations Body on the Peaceful Applications of Outer Space, the only committee of the General Assembly dedicated only to international cooperation in the peaceful uses of space (COPUOS).

The UN Register of Objects Launched into Outer Space is maintained by UNOOSA, which is also in charge of carrying out the Secretary-General’s responsibilities under international space law.
