Heart Aerospace's X1 demonstrator, a 25,000-pound battery-electric aircraft with a 106-foot wingspan, flew for 27 minutes on roughly $5 of electricity — proving megawatt-scale electric propulsion works at commercial airliner size.

Terra reached its designed orbit on 24 February 2000 after 11 weeks of checkout and eight ascent burns. In 2020 the flight team stopped fighting the drift. NASA now projects end-of-science in February 2027.
In 1995, biologists released 41 wolves into Yellowstone after a 70-year absence. Three decades later, the story of what they changed — and what they didn't — is being rewritten.
