Marie Curie was a pioneering Polish-born physicist and chemist renowned for her groundbreaking research on radioactivity. She was the first woman to win a Nobel Prize and remains the only person ever awarded Nobel Prizes in two different scientific fields—Physics (1903) and Chemistry (1911).

Curie, along with her husband Pierre Curie and Henri Becquerel, shared the 1903 Nobel Prize in Physics for their work on the phenomenon of radioactivity, a term she coined. She later discovered two new elements, polonium and radium, and was awarded the 1911 Nobel Prize in Chemistry for isolating pure radium. Her research fundamentally changed scientific understanding of atomic structure and radioactivity, and she championed the use of radiation in medicine, particularly for cancer treatments.

Curie was also the first female professor at the Sorbonne in Paris, and during World War I, she developed mobile X-ray units to assist battlefield medical care. Her dedication to science, despite personal and professional challenges, left a lasting legacy in both scientific research and medical practice.

Geocaching is an outdoor recreational activity that involves using a Global Positioning System (GPS) or a mobile app to navigate to specific coordinates and find hidden containers called geocaches . These containers are hidden all over the world by other participants . Geocaching is often described as a real-world treasure hunt and is considered a family-friendly activity .

Blue Origin Enterprises, L.P. is an American space technology company headquartered in Kent, Washington. The company operates the suborbital New Shepard rocket and the heavy-lift New Glenn rocket. In addition to producing engines for its own rockets, Blue Origin supplies engines for other vehicles, including United Launch Alliance's Vulcan Centaur. It is also working on the Blue Moon human lunar lander for NASA's Artemis program, the Blue Ring spacecraft platform, and the Orbital Reef space station in partnership with other organizations.

Founded in 2000 by Jeff Bezos, Blue Origin initially operated with a very low profile, funded by Bezos's private investments. In 2015, the company achieved a significant milestone with the first uncrewed launch and landing of the New Shepard and announced plans for New Glenn. In 2021, New Shepard completed its first crewed mission with Bezos himself on board, crossing the Kármán line, the conventional definition of the edge of space, 100 kilometers (62 mi) above sea level. Another key achievement came in January 2023 when the company delivered its first BE-4 rocket engine to United Launch Alliance.[2] Despite these milestones, Blue Origin has faced criticism for its perceived slow progress, particularly when compared to SpaceX. Addressing these challenges, the company underwent a leadership change in September 2023, appointing Dave Limp as CEO to succeed Bob Smith.[3]

On January 16, 2025, Blue Origin reached orbit with the first launch of the New Glenn vehicle.[4]
