ViewThe Rise and Fall of NASA's NERVA Program The Nuclear Engine for Rocket Vehicle Application (NERVA) program represents one of the most ambitious chapters in the history of space exploration. Emerging in the 1960s, NERVA was envisioned as a revolutionary propulsion concept for deep space travel, part...
ViewConjunction-class Mars missions use low-energy transfers both to and from Mars, so they need less propellant, but they spend much longer in flight and on the surface, with a Mars stay of roughly 500 days and a total mission of about 1,000 days. Opposition-class missions use one low-energy transfer a...
ViewA conjunction-class Mars mission uses low-energy transfers to Mars and back, with a long stay at Mars of roughly 500 days, for a total mission duration of about 1,000 days. An opposition-class mission uses one low-energy transfer and one high-energy transfer, with a short stay at Mars of typically l...
ViewIn the source, a conjunction-class Mars mission is one that uses low-energy transfers to Mars and back, with a long stay at Mars of roughly 500 days, so the total mission lasts about 1,000 days. An opposition-class mission uses one low-energy transfer and one high-energy transfer, with a short stay ...
ViewHumans to Mars tells the story of fifty years of planning for a crewed mission to Mars, from early bold sketches in the 1950s to more practical designs in the 1990s. It shows how each era changed the plan as new spacecraft, new science, and new political realities came into view. One striking detail...
View*Humans to Mars: Fifty Years of Mission Planning, 1950-2000* is a NASA History Division monograph by David S. F. Portree, published in February 2001 as Monographs in Aerospace History series number 21. It surveys the evolution of piloted Mars mission planning over roughly half a century, from early ...

ViewBased on these sources, the most shareable “weird history” and forgotten space-tech topics for space fans are: Cold War moon and Mars plans that never flew, like Project Mars, NERVA, Project Horizon, and the Nova rocket concept. Another big topic is secret or abandoned military space stations, es...
ViewIn 2024-2025, the biggest recurring topics around NASA’s Mars planning were the Moon-to-Mars strategy, in-situ resource utilization, radiation risk, and whether Artemis hardware and operations are building the right experience for Mars. NASA describes Artemis as a step toward “the first crewed missi...

ViewWatch the split screen: without an aerator, water falls as one hard column and splashes widely, but with one, the stream is broken into tiny mini-streams that interfere with each other and cut the splash. Then zoom into the mesh, where air is pulled into the water and the stream is broken into dropl...
