UNICEF
The UN International Children's Emergency Fund (UNICEF) was established by the General Assembly (GA res. 57 (I) (1946) to provide emergency assistance to children in war-ravaged countries following World War II. By GA res. 417 (V) (1950), the UN General Assembly charged it with addressing the needs of children in developing countries. GA res. 802 (VIII) (1953) extended UNICEF'S mandate indefinitely, with an emphasis on programmes giving long-term benefits to children everywhere, particularly those in developing countries, and changed the organization's name to the United Nations Children's Fund but retained the UNICEF acronym.

The heavy bombardment was a period when leftover planetesimals hit planets during the solar system's first hundred million years.
