After the extinction of the dinosaurs, approximately 66 million years ago, the rise of mammals begun. There were mammals on earth before that date, but after the Cretaceous–Paleogene (K–Pg) extinction event (a mass extinction of some three-quarters of the plant and animal species on Earth—including all non-avian dinosaurs), mammals took over the medium- to large-sized ecological niches.
Some of them reached enormous sizes, usually they were larger than today’s counterparts (with the exception of whales). Here are some of the largest known prehistoric mammals.

On November 6th, 2015, UP Aerospace Inc. launched the 20-foot (6 meter) tall SL-10 rocket (a small sounding rocket) into near-space. The mission was to deploy the Maraia Capsule testing the aerodynamics and stability of the payload on re-entry to the atmosphere. The rocket reached an altitude of 396,000 feet (120,700 meters) and speeds up to Mach 5.5 (3800 mph or 6115 km/h) at engine burnout. The event was recorded with an attached GoPro. The action camera has recorded amazing images of Earth and the space.

On March 17, 1941, John W. Campbell, editor of Astounding Science Fiction, asked Isaac Asimov that: “What, if people see the stars once in a thousand of years?” Campbell has had read Ralph Waldo Emerson’s 1836 essay “Nature” and Emerson was saying in the first chapter that “If the stars should appear one night in a thousand years, how would men believe and adore, and preserve for many generations the remembrance of the city of God!”

We evolved here on Earth, and for thousands of years, we just thought the Earth is also the universe, or at least the most important and the biggest part of it. Our brains, our minds, has been adapted the life on Earth and the basic survival needs. So we can deal with the moderate sized objects which have moderate velocity, we can understand the small numbers like 1, 2, 50, we can conceptualize the small distances like two kilometer, or the distance from our “cave” to the nearest river. But when the numbers and distances get bigger, I mean much bigger, like the distance from Earth to the Sun, it become incredibly difficult to conceptualize.

April 8, 2016 was a historical day which marking a new milestone on humanity’s space adventure: after delivering CRS-8 cargo on its way to the International Space Station, SpaceX Falcon 9 Flight 23, the third flight of the full-thrust version landed vertically on the drone ship Of Course I Still Love You over the Atlantic ocean, 300 km from the Florida coastline, achieving a long-sought-after milestone for the SpaceX reusability development program.

On August 6, 1945, during the World War II, an American Boeing B-29 Superfortress bomber named “Enola Gay” dropped the world’s first deployed atomic bomb codenamed “Little Boy” over the Japanese city of Hiroshima. The bomb exploded with 15 kilotons of TNT (63 TJ) of energy and caused horrendous destruction to the city. Approximately 66,000 people were killed as a direct result of the blast, and 69,000 were injured to varying degrees. Within four months, the number of the fatalities would reach 90,000–146,000 people due to the acute effects of the atomic bomb.

Extreme sports media company based in Jackson Hole, Wyoming, Teton Gravity Research released the first ultra HD drone footage of the Himalayas. The footage shot with the GSS C520 system, one of the most advanced 5-axis gyro-stabilized camera system in the world. Filmed from a helicopter with a crew flying from Kathmandu at 4,600 feet (1,400 meters) up to 24,000 feet (7,300 meters) on supplemental oxygen, these are some of the most stable, crisp, clear aerial shots of these mountains ever released, which include Mount Everest, Ama Dablam, and Lhotse.

2015 Norwegian catastrophe drama film The Wave tells a fictional story about Geiranger, a small tourist village in Sunnmøre region of Møre og Romsdal county in the western part of Norway. In the movie, the village threatened a huge mass of rock tumbles into Geirangerfjord (which is one of Norway’s most visited tourist sites, and it was listed as a UNESCO World Heritage Site in 2005). The rock sets off a 300 feet megatsunami. The villagers must rush to the mountains in ten minutes, before “the wave” reaches them.
