Armstrong and Aldrin recorded themselves for television broadcast, showing viewers inside their cabin. After landing, they used water spraying techniques to saturate the surface before conducting soil cohesion tests on lunar soil samples collected from Luna. Armstrong completed his scheduled maneuvers by undocking Eagle from Columbia and orbiting around the Moon, while transmitting radio communications…
Due to its closeness to the Sun, Mercury experiences extreme temperatures during daylight. At nighttime without an atmosphere to retain warmth, however, its warmth quickly dissipates into space. Earth is second only in density and features an immense iron core, while Venus boasts greyish-brown skin with bright streaks known as crater rays. Temperature Mercury, being…
As soon as sunlight reaches Earth’s atmosphere, gases and particles scatter it all around in all directions – blue light being scattered more widely than other hues; hence why the sky appears blue. Irish scientist John Tyndall first demonstrated this principle in 1859 by passing a beam of white light through a liquid with floating…
Since 2010, OTV-7, an uncrewed space plane, has conducted numerous technology experiments on long orbital flights. Most recently, its service module enabled OTV-7 to host additional experiments. Its cargo included a Naval Research Laboratory project to test technology to convert sunlight to electricity and NASA experiments on how long-duration space exposure affects materials and seeds….
Infantrymen wear a light blue cord around their right shoulder as a symbol of their connection to the branch; this cord is known as a fourrager. Only soldiers and officers with an infantry military occupational specialty (MOS 11A and those who complete infantry One Station Unit Training) may wear the cord. This includes recruits completing…
Once again after an especially harsh winter it’s incredible to witness the first signs of spring: snowdrops blooming (this year they could even be found blooming as early as January!), migrants like warblers and woodcocks arriving, etc. From March through April you can hear birds begin singing again in their dawn chorus. Bumblebees buzz about…
Armstrong and Aldrin used the two-hour moon walk to deploy Early Apollo Scientific Experiment Package instruments as well as collect rock and soil samples. Armstrong realized as they approached landing, the automatic landing system was leading them towards a rocky crater and ordered mission controllers to authorize a risky manual maneuver to address it. Apollo…
The sky is blue due to how light is scattered by our atmosphere. Sunlight contains all visible frequencies; however, only certain ones are absorbed or reflected back; leaving behind other frequencies to be dispersed into blue and cyan hues of the spectrum. Some languages provide specific terminology to distinguish different hues of blue and green;…
Landing on the Moon requires immense amounts of energy. That energy must be carefully managed in order to achieve an efficient landing on its surface. Surveyor 1 was the inaugural spacecraft of its kind to take high-resolution photos and create a map of potential Apollo landing sites on the Moon’s far side. Controllers deliberately crashed…
