Kids can gain a great deal of knowledge about our Solar System and Spanish by listening to songs with catchy rhythms that help them memorize words easily. They may also watch films featuring Spanish dialogue that provide additional information about planets and objects within it. Mars is a parched planet with limited water supplies and…
Mars can be both beneficial and destructive depending on its position in one’s horoscope. When properly aligned, Mars can bring health, wealth, strength and protection, while when misplaced it may create aggression and war. Also referred to as Kuja in Sanskrit and Sevvai in Tamil. Mars can reach Earth in roughly 24 hours and 37…
Many people incorrectly assume that the sky and water appear blue because of reflection; this is not actually true; their hue comes from something called Rayleigh scattering. As sunlight passes through Earth’s atmosphere it is scattered by gases such as oxygen and nitrogen, with shorter wavelengths (blues) more easily scattered than longer ones (reds). This…
Voyager spacecraft are now in an area known as the heliosheath at the outer limits of our sun’s influence, carrying 11 scientific instruments with them for planet observations such as cameras and spectrometers. These travelers have already explored many of the outer planets, leaving behind Golden Records with each one to send a message from…
Mercury and Venus are the innermost planets and often appear before or after the Sun in the sky, shining brightly due to their thick atmospheres. Venus suffers because its solar energy is quickly converted to heat that radiates back out as light, making escape difficult. Furthermore, there are few old craters and no evidence of…
Cassini performed 20 ring-grazing orbits that brought it within 1000 kilometers of Saturn’s outermost edge, offering incredible close encounters. On one of those orbits, a tiny storm ballooned into an enormous, billowing mass of cloud and gas. This Great White Storm verified long-held theories regarding water-ice geysers on Enceladus, a moon believed to contain a…
Sunlight travels through Earth’s atmosphere where it is redirected by gas molecules and small particles into various directions, with blue wavelengths becoming scattered more readily than others, giving the sky its characteristic color during daylight hours. Sunrise and sunset sunlight must pass through more of the atmosphere, leading to more blue being scattered away and…
Over the last 50 years, astronauts have built up an extensive legacy in performing on-orbit inspection, servicing and assembly tasks. Unfortunately, such activities are very costly, time consuming, and require extensive pre-launch testing before launch. Core technologies for on-orbit manufacturing and assembly are currently under development utilizing teleoperation, robotics and autonomy technologies. These approaches can…
Commander Neil Armstrong made history when he took a step out of Eagle onto the moon’s surface in front of millions watching on television, proclaiming with words like, “one small step for man, one giant leap for mankind” as his words became an international rallying cry of achievement and pride. First time viewers of television…
