Mars Curiosity Rover Celebrates Sol 2,000

This week, NASA’s Mars Curiosity Rover celebrated its 2,000th Martian day (or Sol) on the Red Planet. The nuclear-powered rover was launched from Cape Canaveral on November 26, 2011, and landed on Aeolis Palus in Gale Crater on Mars on August 6, 2012. A Mars day is slightly longer than a day here on Earth: a sidereal day is 24 hours, 37 minutes, and 22 seconds (on Earth, it is 23 hours, 56 minutes and 4.1 seconds) and a solar day is 24 hours, 39 minutes, and 35 seconds (on Earth, 24 hours).

“Wrong” by Freethink Media

Today, I stumbled upon a Facebook page, titled “Wrong” by Freethink. Then I searched them on YouTube and saw that they also have a YouTube channel. They published great videos on interesting subjects. I would strongly recommend you to take a look at their very underrated YouTube channel and Facebook page.

Here some of their great videos below:

Exoplanet Travel Bureau by NASA – Interactive 3D Images

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.

Watch: Rotating Moon from the Lunar Reconnaissance Orbiter

NASA APOD (Astronomy Picture of the Day) published an amazing video showing a rotating Moon. In fact, no one sees the Moon rotate like this. We see only one side of the moon, because the Moon is tidally locked to Earth. But, thanks to modern digital technology combined with many detailed images returned by the Lunar Reconnaissance Orbiter (LRO), a high-resolution virtual Moon rotation movie has been composed.

Watch: Does saving more lives lead to overpopulation?

The Earth is getting more crowded every single day. As of December 2017, the world population was estimated at 7.6 billion. It took 200,000 years for our human population to reach 1 billion, and only 200 years to reach 7+ billion. The United Nations estimates it will further increase to 11.2 billion in the year 2100. Another fact is, now people live longer and healthier lives, and infant mortality rate (IMR) is declining rapidly. In the early 1800s, newborn were expected to live only a dismal of 30 years. But, thanks to advances in farming, medicine, and sanitation, a newborn today can expect to live more than 70 years. Is that trend dangerous? Does saving more lives lead to overpopulation? In the video below, Bill Gates answers that question.

People today are living longer, healthier, and happier lives than ever before

In a video published by Bill Gates on his Youtube channel, originally titled “Humanity is fighting back against the Grim Reaper”, Steven Pinker, the Canadian-American cognitive psychologist, linguist, popular science author and Johnstone Family Professor in the Department of Psychology at Harvard University explains why people today are living longer, healthier, and happier lives than ever before. Pinker is one of Gates’ favorite authors.

Watch: Others Will Follow (Short Sci-Fi Film)

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.

Moon has been formed earlier than Earth? The “Synestia Theory” says so

According to a new study, the Moon might have been formed a thousand years earlier than Earth. The new, “synestia theory” suggests a Mars-sized object smashed into the proto-Earth. The “giant impact” vaporized about 10 percent of the rock and liquefied the rest, and created a rapidly spinning donut-shaped mass of vaporized rock called “synestia”. The synestia eventually shrunk and cooled. Computer models demonstrated that the Earth subsequently emerged about 1,000 years after the moon.
