Asteroid impact event. Lateral sectioned view of an asteroid impact, similar to that which is thought to have caused the extinction of the dinosaurs around 65 million years ago. The impact took place at sea near the coast of the Yucatan Peninsula in Mexico, forming the Chicxulub crater (around 200 kilometres across). The impact threw trillions of tons of dust into the atmosphere and sent tsunamis (massive waves) around the globe, destroying coastal areas. Dust and water vapour in the atmosphere lowered global temperatures. Plant and then animal life began to die off. The dinosaurs never recovered, and mammals rose to become the dominant form of life.

Workers with NASA???s Exploration Ground Systems (EGS) paint the bright red NASA ???worm??? logo on the side of an Artemis II solid rocket booster segment inside the Rotation, Processing and Surge Facility (RPSF) at Kennedy Space Center in Florida on Tuesday, Jan. 30, 2024. The EGS team used a laser projector to mask off the logo with tape, then painted the first coat of the iconic design. The booster segments will help propel the Space Launch System (SLS) rocket on the Artemis II mission to send four astronauts around the Moon as part of the agency???s effort to establish a long-term science and exploration presence at the Moon, and eventually Mars.
