Wildfires have become more frequent due to climate change and human activities, but they have burned throughout history. Drought and dry winds fueled the January 2025 wildfires in California, some of the worst the state has seen.

Humans have developed different methods for preventing and stopping wildfires. Indigenous peoples such as Native Americans and Aboriginal Australians have set controlled fires to burn brush and prevent larger fires later. Firefighters use engines, trucks, and planes to tame fires with water and chemicals. Learn all about wildfires, from how they start and how they are classified to how they can be stopped and prevented.

NASA's Artemis missions aim to put people on the Moon again. Humans have not been to the Moon since the US government canceled its Apollo program in 1972. After President Barack Obama announced funding for NASA to create a new space program, NASA revealed Artemis. Artemis's primary aim was ambitious but simple: Fly humans to the Moon so they could learn to live on another world. Throughout six initial Artemis missions, NASA aims to land astronauts and equipment on the Moon and bring modules into the Moon's low orbit. The missions will also train astronauts to live on Mars. NASA can't achieve these ambitious goals alone, though. They are partnering with companies such as SpaceX and Blue Origin to build rockets and lunar vehicles. Explore the history of the Artemis missions, including the successes and failures required to land humans on the Moon and beyond.
