It’s been 50 years since mankind first stepped foot on the moon, and to celebrate, we’re showing the full length clip of the moon landing from miniseries, “From the Earth to the Moon. #HBO #FromTheEarthToTheMoon

With the launch period of NASAs Mars 2020 Perseverance rover opening in 14 weeks, final preparations of the spacecraft continue at the Kennedy Space Center in Florida. In the past week, the assembly, test and launch operations team completed important milestones, fueling the descent stage — also known as the sky crane — and attaching the Mars Helicopter, which will be the first aircraft in history to attempt power-controlled flight on another planet.
After the descent stage fueling, the system that will deliver the Mars Helicopter to the surface of the Red Planet was integrated with Perseverance. The helicopter, which weighs 4 pounds (1.8 kilograms) and features propellers 4 feet (1.2 meters) in diameter, is cocooned within the delivery system. In one of the first steps in the day-long process on April 6, technicians and engineers made 34 electrical connections between the rover, the helicopter and its delivery system on the rovers belly. After confirming data and commands could be sent and received, they attached the delivery system to the rover.
Finally, the team confirmed the helicopter could receive an electrical charge from the rover. Before being deployed onto the surface of Jezero Crater, the Mars Helicopter will rely on the rover for power. Afterward, it will generate its own electrical power through a solar panel located above its twin counter-rotating propellers.
The helicopter will remain encapsulated on the rovers belly for the next year and will be deployed around the beginning of May — roughly two-and-a-half months after Perseverances landing. Once the rover drives about 330 feet (100 meters) away and the helicopter undergoes an extensive systems check, it will execute a flight-test campaign for up to 30 days.
The Perseverance rover is a robotic scientist weighing 2,260 pounds (1,025 kilograms). It will search for signs of past microbial life, characterize the planets climate and geology, collect samples for future return to Earth and pave the way for human exploration of the Red Planet. No matter what day Perseverance launches during its July 17-Aug. 5 launch period, it will land on Mars Jezero Crater on Feb. 18, 2021.
In her final days as Commander of the International Space Station, Sunita Williams of NASA recorded an extensive tour of the orbital laboratory and downlinked the video on Nov. 18, just hours before she, cosmonaut Yuri Malenchenko and Flight Engineer Aki Hoshide of the Japan Aerospace Exploration Agency departed in their Soyuz TMA-05M spacecraft for a landing on the steppe of Kazakhstan. The tour includes scenes of each of the stations modules and research facilities with a running narrative by Williams of the work that has taken place and which is ongoing aboard the orbital outpost.
The stakes are high for NASAs newest rover. Years of hard work and millions of dollars could be burnt into the Martian soil if one mistake has been made!
The Perseverance Rover represents the latest in a long line of remote robotic exploration vehicles sent to the red planet over the last 44 years.
It seeks to answer further questions raised by it’s predecessor Curiosity – which made its landing on Mars in 2012 and was the most ambitious mission flown by NASA at that time.
This ‘little engine that could’ has now been on Mars for almost 8 Earth years – 2835 Mars days to be exact. It has fulfilled it’s primary mission of finding evidence of organic molecules and geological change on Mars.
It continues to explore and search for water in the form of ice.
All this was possible due to Curiositys successful landing. But how likely is Perseverance to have a successful touchdown?

THE SUN is the star at the center of the Solar System and is by far the most important source of energy for life on Earth. It is a nearly perfect spherical ball of hot plasma with internal convective motion that generates a magnetic field via a dynamo process. Its diameter is about 109 times that of Earth, and it has a mass about 330,000 times that of Earth, accounting for about 99.86% of the total mass of the Solar System. Chemically, about three quarters of the Suns mass consists of hydrogen, whereas the rest is mostly helium, and much smaller quantities of heavier elements, including oxygen, carbon, neon and iron
THE PISTOL STAR is a blue hypergiant and is one of the most luminous known stars in the Milky Way Galaxy. It is one of many massive young stars in the Quintuplet cluster in the Galactic Center region. The star owes its name to the shape of the Pistol Nebula, which it illuminates. It is located approximately 25,000 light years from Earth in the direction of Sagittarius. It would be visible to the naked eye as a fourth magnitude star if it were not for the interstellar dust that completely hides it from view in visible light.
VY CANIS MAJORIS (VY CMa) is a red hypergiant star located in the constellation Canis Major. It is one of the largest stars (at one time the largest known) and also one of the most luminous of its type, and has a radius of approximately 1,420 ± 120 solar radii (equal to a diameter of 13.2 astronomical units, or about 1,976,640,000 km), and is located about 1.2 kiloparsecs (3,900 light-years) from Earth.
UY SCUTI is a bright red supergiant and pulsating variable star in the constellation Scutum. It is one of the leading candidates for being the largest known star by radius and is also one of the most luminous of its kind. It has an estimated average median radius of 1,708 solar radii, or a diameter of 2.4 billion km (1.5 billion mi; 15.9 AU); thus a volume 5 billion times that of the Sun. It is approximately 2.9 kiloparsecs (9,500 light years) from Earth.

Astrophysicist Dr. Neil DeGrasse Tyson was asked by a reader of TIME magazine, “What is the most astounding fact you can share with us about the Universe?" This is the answer he gave…
The Hubble Space Telescope (HST) is a space telescope that was carried into orbit by a Space Shuttle in 1990 and remains in operation. A 2.4-meter (7.9 ft) aperture telescope in low Earth orbit, Hubbles four main instruments observe in the near ultraviolet, visible, and near infrared spectra. The telescope is named after the astronomer Edwin Hubble.
Hubbles orbit outside the distortion of Earths atmosphere allows it to take extremely high-resolution images with almost no background light. Hubbles Deep Field has recorded some of the most detailed visible-light images ever, allowing a deep view into space and time. Many Hubble observations have led to breakthroughs in astrophysics, such as accurately determining the rate of expansion of the universe.
Although not the first space telescope, Hubble is one of the largest and most versatile, and is well known as both a vital research tool and a public relations boon for astronomy. The HST was built by the United States space agency NASA, with contributions from the European Space Agency, and is operated by the Space Telescope Science Institute. The HST is one of NASAs Great Observatories, along with the Compton Gamma Ray Observatory, the Chandra X-ray Observatory, and the Spitzer Space Telescope.
Space telescopes were proposed as early as 1923. Hubble was funded in the 1970s, with a proposed launch in 1983, but the project was beset by technical delays, budget problems, and the Challenger disaster. When finally launched in 1990, Hubbles main mirror was found to have been ground incorrectly, compromising the telescopes capabilities. The optics were corrected to their intended quality by a servicing mission in 1993.
Hubble is the only telescope designed to be serviced in space by astronauts. Between 1993 and 2002, four Space Shuttle missions repaired, upgraded, and replaced systems on the telescope; a fifth mission was canceled on safety grounds following the Columbia disaster. However, after spirited public discussion, NASA administrator Mike Griffin approved one final servicing mission, completed in 2009. The telescope is now expected to function until at least 2014, and possibly 2020. Its scientific successor, the James Webb Space Telescope (JWST), is currently scheduled to be launched in 2018.
Hope you enjoyed it as mush as i did making it!

With the season premiere of Game of Thrones still fresh in mind, I thought this might be appropriate.
Being a big fan of both modern fantasy and old «Spaghetti Westerns», Ive tried to do a cover of Ramin Djavadis Theme for Game of Thrones, in the fashion of Ennio Morricones incredible western-film scores.
