Now we’re living on a warm, hospitable planet. As Carl Sagan has said “That’s home. That’s us. On it everyone you love, everyone you know, everyone you ever heard of, every human being who ever was, lived out their lives.” We, humans, are the unquestionable rulers of our little oasis in a hostile universe. But all things must pass. The life on Earth, even the planet itself, won’t last forever. What’s more, the humans may go extinct before our planet (and probably before the life on it) dies out. Here some possible (and horrible) ways how planet Earth (or, at least, life on Earth) could die.Continue reading How Earth Could Die – 9 Horrible Ways
Hubble Space Telescope was launched on April 24, 1990, and entered service on May 20, 1990. Since then, it has observed all the planets in our Solar System, apart from Earth and Mercury. Earth is far better studied by geologists on the ground and specialized probes in orbit. Hubble can’t observe Mercury as it is too close to the Sun, whose brightness would damage the telescope’s sensitive instruments.
Here are the best images of the planets (except Earth and Mercury) and some non-planets of our Solar System through the eye of Hubble Space Telescope.Continue reading Solar System through the eyes of Hubble Space Telescope
I am one of the few African-American aerospace engineers who helped design the Apollo spaceships that took men to the Moon. My great-grandfather was a slave in Claiborne, Alabama, who used primitive tools to work the land. My father was born in Alabama before the Wright brothers made mankind’s first flight. He lived to see men walk on the Moon, twin robotic biology labs land on Mars, and a fleet of four space probes on their way to the stars. But many black people, like the late Reverend Ralph Abernathy, felt that the money used to make these amazing things happen would have been better spent on helping the poorest descendants of American slaves.Continue reading Space exploration is still the brightest hope-bringer we have
NASA has published a video showing Curiosity Rover‘s (Mars Science Laboratory) proposed route on Mars’ Mount Sharp (Aeolis Mons), a mountain rising 5.5 km (18,000 ft) high from the valley floor. The animated video shows what it would be like to soar over Mount Sharp, officially Aeolis Mons, which the Curiosity has been climbing since 2014.Continue reading Fly over Mount Sharp on Mars with this NASA video
NASA’s Mars InSight lander captured a series of sunrise, sunset, and clouds images. On April 24 and 25, 2019 (the 145th Martian day, or sol, of the mission), Instrument Deployment Camera (IDC) on the spacecraft’s robotic arm captured sunrise and sunsets. Another camera, called Instrument Context Camera (ICC) beneath the lander’s deck captured drifting clouds across the Martian sky at sunset.Continue reading InSight captures a sunrise, sunset, and clouds on Mars
In March 2019, NASA’s Mars Curiosity rover captured two solar eclipses created by each of the planet’s tiny moons, Phobos and Deimos.Continue reading NASA’s Curiosity Rover captures two solar eclipses on Mars
Before going silent due to a huge dust storm on June 10, 2018, NASA’s Mars Exploration Rover Opportunity documented an amazing 360-degree panorama from multiple images taken at what would become its final resting spot in Perseverance Valley. The Mars rover collected these images over the course of 29 days.Continue reading Opportunity Rover’s Parting Shot Was a Beautiful Mars Panorama
Since the launch of the first artificial Earth satellite, Sputnik 1, on October 4, 1957, we launched thousands of spacecraft into Earth orbit and beyond. A fraction of them are still functioning, but what happened to the vast majority of them? “The Curious Droid” published another informative video titled “What happens to old spacecraft?”Continue reading Watch: What happens to old spacecraft?
Have you ever wondered how the Sun would look from the other planets in our solar system? Here is a visual showing the apparent size of the Sun from the planets of the solar system, including Earth.Continue reading Apparent Size of the Sun from other planets
NASA’s InSight lander has started providing a daily Mars weather report everyone can see. The American space agency has created a dedicated web page on the NASA InSight mission website to share that information.Continue reading Mars weather service by NASA’s InSight Lander
