Children often ask why the sky is blue, making it one of the most challenging questions to answer without sounding too technical or scientific. Answer lies within how light travels through our atmosphere. When sunlight enters Earth’s atmosphere, its beams get scattered by gas molecules; longer wavelengths, such as red and orange hues pass more…
An extensive space program requires considerable finances. Solar panels, dialysis treatment systems and security systems were all created due to or inspired by Apollo missions. This manuscript provides a high-fidelity reconstruction of Project Apollo costs, including annual cost data and program-by-program cost breakdowns. Furthermore, inflation adjustments based on two NASA cost reporting indices have also…
Miller uses a mix of broadcast TV footage, home movies and never-before-heard NASA audio recordings to examine all missions within the Apollo Space Program – winning him an Emmy award in 2011. By forgoing traditional talking heads or Voice-Of-God commentary he adds more context and makes each moment feel more than just about Aldrin, Armstrong…
Usually when asked what planet is closest to Earth, most will answer Venus; however, this may not be accurate.

Mercury Mercury, the closest and smallest…

Human bodies are truly remarkable. From individual atoms to large chromosomes, our bodies’ capabilities seem almost unbelievable. Infants begin life with roughly 350 bones; as they age and fuse together over time, adults only possess 206. Additionally, there are over 60,000 miles of blood vessels running through our bodies that if laid out would cover…
Seahorses are unique among vertebrates in that males carry their offspring. They live in coral reefs or other marine environments where their natural camouflage helps them avoid predators. Furthermore, their prehensile tails allow them to grasp onto objects for better gripping power. Males get pregnant Seahorses are notable examples of animals defying gender norms. While…
Once a satellite or space station reaches its end of life, its final option may either be further space exploration (which requires more fuel), or controlled reentry back onto Earth – to minimize risks to people, officials select an isolated spot on our planet as the target for controlled reentry. Point Nemo Point Nemo, named…
Children tend to be very inquisitive about their surroundings and are always asking why the sky is blue. One common query from children is “why does the sky appear to be so blue”. Light that enters the atmosphere is dispersed into different directions by gas particles called Rayleigh scattering, giving rise to blue skies at…
