Using data provided by Lunar Reconnaissance Orbiter spacecraftNotes 1 since 2009, NASA has published an amazing virtual Moon tour in 4K Ultra HDNotes 2. As the visualization moves around the near side, far sideNotes 3, north and south poles, interesting features, sites, and information gathered on the lunar terrain get highlighted.

Today I stumbled upon on a beautiful web site: the Climate Reanalyzer. In fact, Chris Hadfield, the retired Canadian astronaut and also who was the first Canadian to walk in space, tweeted about the web site, saying “The current bulge of cold”. Then I visited the web site and found it really informative.

Will we ever visit other stars? Maybe, in the distant future, if humans won’t become extinct, our grand grand … (insert a hundred or a thousand grands here) children can stand on an exoplanet’s surface someday. But, we don’t have to wait. NASA has opened a new web page, an “Exoplanet Travel Bureau”, and we can, at least, see the artists’ imaginations of what an exoplanet surface look like, based on available data. NASA warns, there are no actual images of the exoplanets, obviously. With interactive 3D images, it is still an exciting experience.

A great short science fiction film, “Others Will Follow”, created and directed by Andrew Finch and published on Vimeo, tells the story of a manned Mars mission. An accident occurs and the spacecraft breaks apart, the last survivor (we don’t see what happens to the rest of the crew, but presumably they have died) manages to send an inspirational message back to Earth. A must-watch.

The Lion (Panthera leo) is the second largest cat in the world, after the tiger. The lion and tiger are closely related and they share a very similar body type. As its scientific name suggests, Lion is one of the five members of the Panthera genus.Notes 1 Here are 20 amazing lion facts.

Spacewalking or Extravehicular activity (EVA) is any activity done by an astronaut or cosmonaut outside a spacecraft beyond the Earth’s appreciable atmosphere (a moonwalk is also an EVA). The first skywalker was the Soviet cosmonaut Alexey Arkhipovich Leonov. He became the first human to conduct extra-vehicular activity (EVA) on March 18, 1965; exiting the capsule during the Voskhod 2 mission for a 12-minute spacewalk. Since this very short EVA, a lot of astronauts/cosmonauts spent many hours outside their spacecraft, mostly for maintenance missions. Here are the top 20 longest spacewalks in history.

NASA astronaut Randy “Komrade” Bresnik, the commander of the Expedition 53 (the 53rd expedition to the International Space Station) has published a beautiful video on his twitter account titled “Through the eyes of a spaceman: One World Many Views”. In the video, Bresnik shared photos of places he’d visited on Earth alongside photos of the same locations he snapped from space. He also wrote: “You don’t have to be in outer space to experience the beauty of our home planet. Capture the beauty of a moment, or the excitement of an instant, and share it with others.”

How old is the Earth? This question preoccupied first philosophers, then scientists, for many centuries. Today, we know that the age of the Earth is approximately 4.54 billion years, with an error range of about 50 million years (4.54 × 109years ± 1%). This number is based on evidence from radiometric dating of the oldest-known terrestrial rocks as well as lunar rock samplesNotes 1 and meteorites.

Philip Metzger is a physicist/planetary scientist who works on technologies for mining the Moon, Mars, and asteroids; for developing extraterrestrial spaceports; and for starting robotic industry in space. He took early retirement from NASA, where he co-founded the KSC Swamp Works. He is now with the planetary science faculty at the University of Central Florida.

John W. Young, the legendary astronaut has died on January 5, 2018, aged 87. During his 42 years of active NASA service, Young flew in six space missions (with seven launches, counting his lunar liftoff), becoming the first astronaut to achieve that number. He was the only person to have piloted, and been commander of, four different classes of spacecraft: Gemini, the Apollo Command/Service Module, the Apollo Lunar Module, and the Space Shuttle (he was the first astronaut to command the Space Shuttle). He was also the ninth person to walk on the Moon as Commander of the Apollo 16 mission in 1972. Young was actually one of only three people to have flown to the Moon twice, others being Jim Lovell and Eugene Cernan.
