Artificial Intelligence in Space

Outer space is considered to be an inhospitable place to live since there is no breathable air and space travel significantly alter your bodies due to increased doses of radiation in the form of high energy charged particles. Radiation is energy diffused in the form of rays, electromagnetic waves, and particles. These high doses of radiation can cause damage to your body cells by breaking up the atoms and molecules. While we don’t know accurately what the effect of several long journeys into space is but we know that there is a high risk of developing many health problems – including back problems, osteoporosis (brittle bones), cancer and damage to the nervous system.

Watch: Apollo 11’s journey to the moon, annotated

On July 20, 1969, at 20:17 UTC, two American astronauts, Apollo 11 mission commander Neil Armstrong and pilot Buzz Aldrin landed the lunar module Eagle on the Moon. It was the first time humans set foot on another planetary body than Earth, making the moon landing probably the most monumental event in history.

Vox.com published a beautiful video highlighting the key moments of the Apollo 11 mission.

Watch: The Secrets behind Earth’s Multi-colored Airglow

Even we could remove the effects of the moonlight, starlight and diffused sunlight from the far side, the Earth’s night sky would never totally dark. This phenomenon is known as Airglow (also called nightglow). Airglow is a faint emission of light by Earth’s atmosphere (or any planetary atmosphere).

How NASA Missions Save Lives on Earth

Satellites are blessings to mankind in the true sense. NASA has been continuously striving to launch the satellite for the betterment of the environment and to understand the future aspects. The American space agency not only employs the larger number people themselves but also helps other aerospace companies to employ them.

Amazing Moon-Earth Photo by the Amateurs using a Chinese Satellite

Amateur astronomers in the Netherlands took an amazing Moon-Earth photo using a Chinese satellite. On May 20, 2018, China launched Queqiao lunar communications relay satellite, a key component of the upcoming Chang’e 4 lunar landing mission. During its journey to the Moon (actually Earth-Moon L2 point Notes 1), it dropped off a pair of student-made small satellites, Longjiang-1 and Longjiang-2, bound for lunar orbit called. Their purpose was testing out future radio astronomy and interferometry techniques.

To find aliens, we must think of life as we don’t know it

From blob-like jellyfish to rock-like lichens, our planet teems with such diversity of life that it is difficult to recognise some organisms as even being alive. That complexity hints at the challenge of searching for life as we don’t know it – the alien biology that might have taken hold on other planets, where conditions could be unlike anything we’ve seen before. ‘The Universe is a really big place. Chances are, if we can imagine it, it’s probably out there on a planet somewhere,’ said Morgan Cable, an astrochemist at the Jet Propulsion Laboratory in Pasadena, California. ‘The question is, will we be able to find it?’

Earth can be a model for detecting vegetation on exoplanets

Back in December 1990, during its flyby of Earth, NASA’s Galileo spacecraft, which studied the planet Jupiter and its moons, as well as several other Solar System bodies, pointed its instruments towards Earth, at the urging of Carl Sagan. And, it has found evidence of life on our planet. This can be a key to detect vegetation on exoplanets – which is a key to a possible intelligent extraterrestrial life.

In a paper published on Nature, researchers wrote “The Galileo spacecraft found evidence of abundant gaseous oxygen, a widely distributed surface pigment with a sharp absorption edge in the red part of the visible spectrum, and atmospheric methane in extreme thermodynamic disequilibrium. Together, these are strongly suggestive of life on Earth.”

5 Surprising Facts about Mars

For eons, skywatchers have been fascinated by the pale red dot that not only unpredictably moves backward in the night sky but also shines a compelling blood-red. Its color, indeed, is one of the first features we notice about Mars. It seizes our attention, and its compelling ambiguity has evoked a deep visceral reaction from the nomad in ancient savannas to modern astronomers. The ancient astronomer may be satisfied to know that, in fact, Mars is literally blood-red: the same chemical reaction that occurs in the iron in Mars’ soil is the same is the same chemical reaction that occurs in the hemoglobin molecule. Mars, is, quite literally, blood red. Even with our cutting-edge technology and science, Mars still bewitches and amazes us as seen with these five surprising facts about Mars.
