Watch: Amazing Time-Lapse Video Showing Earth from the ISS

European Space Agency has published an amazing time-lapse video showing the Earth from the International Space Station (ISS). The space agency wrote “Join ESA astronaut Alexander Gerst for a quick flight from the USA to Africa aboard the International Space Station in this time-lapse filmed 12.5 times faster than actual speed.” You can watch that breathtaking video below:

Song of Saturn and Its Moon Enceladus

NASA has published an amazing video titled “Sounds of Saturn: Hear Radio Emissions of the Planet and Its Moon Enceladus”. The analyze of the data from the Cassini Spacecraft’s Grand Finale orbits showed a surprisingly powerful interaction of plasma waves moving from Saturn to its icy moon Enceladus. Researchers converted the recording of plasma waves into a “whooshing” audio file that we can hear, in the same way a radio translates electromagnetic waves into music.

Much like air or water, plasma (the fourth state of matter) generates waves to carry energy. The recording was captured by the Radio Plasma Wave Science (RPWS) instrument on September 2, 2017, two weeks before Cassini was deliberately plunged into the atmosphere of Saturn.

Top 18 Largest Islands on Earth

An island or isle is any piece of sub-continental land that is surrounded by water. It is believed that there are over 100,000 islands in the world. It’s difficult to put a figure to the exact number as there are different kinds of them in various water bodies including oceans, seas, lakes, and rivers. There is even an island within a lake that is situated on an island located in a lake on an island. Only 322 of them are larger than 1000 km2 (386 sq mi). Here are the top 18 largest islands on Earth. Why 18? Because this is the number of islands that have a land area of greater than 100,000 square kilometers (38,610 square miles).

Russian spacecraft arrived to the ISS in just 3 hours and 40 minutes

Russia’s Progress 70 resupply spacecraft set a milestone for International Space Station operations when it arrived in a record time: just three hours and 40 minutes, or only two Earth orbits (of the ISS). The uncrewed spacecraft delivered the cargo which includes 530 kg of propellant, 52 kg of oxygen gas, 420 kg of water and 1,565 kg of “dry” cargo such as food and other equipment to the space station.

The spacecraft launched at 5:51 p.m. EDT (3:51 a.m. July 10 in Baikonur) from the Baikonur Cosmodrome in Kazakhstan. Less than 10 minutes after the launch, the resupply ship reached preliminary orbit and deployed its solar arrays and navigational antennas as planned. The spacecraft then made two orbits of Earth before docking at 9:31 p.m. EDT to the Pirs Docking Compartment of the International Space Station.

Watch: Top 10 Tallest Rockets Ever Launched

To able to reach the space, we need rockets. Rocket engines work by action and reaction (“To every action, there is always opposed an equal reaction” Notes 1) and push rockets forward simply by expelling their exhaust in the opposite direction at high speed and can, therefore, work in the vacuum of space. Space rockets are usually enormous in size, because the bigger the rocket is, the more thrust can produce its engine and can carry more weight into the orbit. Here are the 10 tallest rockets ever launched in the history of space exploration.

Incredible Images of the Earth and the Moon Captured from Chinese Satellite

On his Twitter account, Andrew Jones, a journalist reporting on China’s space programme and related activities, has published amazing images of the Earth and the Moon captured from China’s Queqiao lunar communications relay satellite, a key component of Chang’e 4 lunar landing mission.

An amazing view of our one and only planet

NASA Astronaut Ricky Arnold published an amazing “selfie” from space on his Twitter account saying “An amazing view of our one and only planet”. He took this selfie during the May 16, 2018 spacewalk to perform upgrades on the International Space Station. We can see the Earth, the beautiful blue marble, reflecting on his helmet’s visor.

During the spacewalk which lasted for 6 hours and 31 minutes, Arnold and fellow NASA astronaut Andrew J. Feustel transferred a Pump Flow Control Subassembly over to Dextre stowed failed PFCS on ESP-1, replaced camera and lights used to film NASA TV, replaced Space to Ground Transceiver Controller, performed get aheads to Install handrails on Radiator Grapple Bars on S1, removed thermal blankets and MLI from two Direct Current Switching Units on ESP-2, and prepped the Flex Hose Rotary Coupler on S1 for replacement. Spacewalk suffered a 7-minute delay because of a water leak which formed ice crystals inside the airlock. The spacewalk brought Arnold’s cumulative EVA (Extravehicular activity) time to over 18 hours.

Alan Bean, the fourth person to walk on the Moon has died

Alan Bean, the fourth person to walk on the Moon has died today (May 26, 2018). He was the fourth person to walk on the Moon: in November 1969, he spent 10+ hours on the lunar surface during Apollo 12 mission, the sixth manned flight in the United States Apollo program and the second to land on the Moon.

Born March 15, 1932, in Wheeler, Texas, Bean received a Bachelor of Science degree in aeronautical engineering from the University of Texas in 1955. He attended the Navy Test Pilot School and accumulated more than 5,500 hours of flying time in 27 different types of aircraft. He was selected to become an astronaut by NASA in 1963 as part of Astronaut Group 3.
