In 1996, two students cooling off in a river found an ancient skull and sparked a 20-year battle over American history
In 1996, two students discovered an ancient skeleton, dubbed "The Ancient One," near the Columbia River. DNA analysis revealed the 9,000-year-old remains are genetically linked to Native Americans, resolving a long-standing debate. This discovery revolutionized archaeology, emphasizing respect for indigenous sovereignty and memory, culminating in the skeleton's return to tribal descendants for a traditional burial.
In 2019, a NASA intern scanning star data noticed a tiny glitch and uncovered a world orbiting two suns
A seventeen-year-old intern at NASA, Wolf Cukier, discovered a unique circumbinary planet, TOI-1338 b, orbiting two stars. His diligent analysis of TESS data revealed an anomaly in light curves, leading to this significant find. This discovery paved the way for identifying a second planet in the same system, highlighting the crucial role of human observation in scientific breakthroughs.
Major setback: Jeff Bezos’ Blue Origin rocket failure could delay NASA’s moon landing plans
Blue Origin's New Glenn rocket experienced a payload deployment failure, impacting its ability to place a satellite into the correct orbit. While not directly affecting NASA's immediate Artemis III mission, this setback introduces uncertainties for future lunar operations and the development of Blue Origin's human landing system, potentially delaying long-term Moon presence goals.
Re-entry: Astronaut’s MTech research shows manual control as a safety fallback
Astronaut Angad Pratap's MTech thesis at IISc proposes a human fallback for compromised spacecraft navigation during re-entry. His research demonstrates astronauts can manually guide a capsule using simplified bank-angle control, a system already being tested for India's Gaganyaan mission.
