100 GB of NASA space photos turned into epic 4K time-lapse

100GB of NASA space photos turned into epic 4K time-lapse





It took over 95,600 NASA photo files taken from the International Space Station and a month of meticulous photo editing to produce this epic high-definition time-lapse video.
The compilation work turned almost 110 Gigabytes of original material into some 40 minutes of raw footage in 4K resolution. Of those Dmitry Pisanko, a Russian photo blogger, selected four minutes of highlights.

Pluto shows its spots to Nasa probe







The science team on the American New Horizons mission to Pluto has released two colour views of the dwarf planet and its biggest moon, Charon.


They were made by combining pictures from the probe’s high-resolution, “black and white” camera, Lorri, and its lower-resolution, colour imager known as Ralph.


The difference in hue between Pluto and Charon is clear.
But what catches the eye are four dark spots on the 2,300km-wide dwarf planet.
Each spot is about 500km across. Quite why they should be so similar in size and spacing is not clear.
Their dominant placing is on the hemisphere that New Horizons will not see during its close flyby on 14 July.

However, there should be ample opportunity to study them in the days leading up to the encounter.
“It’s a real puzzle - we don’t know what the spots are, and we can’t wait to find out,” said New Horizons principal investigator, Alan Stern, of the Southwest Research Institute.
“Also puzzling is the longstanding and dramatic difference in the colours and appearance of Pluto compared to its darker and greyer moon Charon.”

If, as scientists think, Pluto and Charon are the products of a collision between two primitive bodies in the early Solar System, one might expect them to look more similar.
New Horizon’s flyby data will hopefully provide the answer.
The US space agency (Nasa) mission is now closing in on Pluto and its five moons.
The moment of closest approach on the 14th will take place at 11:49 GMT, when the probe is just 12,500km above the surface.



It is moving too fast - at 13.7km/s - to go into orbit, and it will simply scream past the dwarf and its satellites, gathering as much data as it can.
No pictures will be sent back to Earth on the day itself; the spacecraft will be too busy executing its pre-programmed observation campaign.
Instead, the first images from the flyby should be presented on the following day, on 15 July.
Controllers have decided not to alter the course of the probe.
They had been looking for icy debris in the vicinity of Pluto that might pose a collision hazard, but could find nothing obvious.
New Horizons was commanded to make a thruster burn earlier this week, to speed it up ever so slightly.
This will ensure the spacecraft reaches a precise point in space and time to carry out the pre-programmed observation sequence.
The probe must spin around to take pictures of all the different targets, and if its navigation is off by even a small amount it will be looking in the wrong direction at the critical moment.
On Thursday, New Horizons was just under 15 million km from Pluto, but 4.7 billion km from Earth.
The vast distance to the probe's home world means a radio signal takes about 4.5 hours from sending to receipt.

#UAE Islamic affairs authority warns Muslims against a mission to Mars

The Oscar-nominated film "Gravity" traces the harrowing tale of astronaut Ryan Stone after a mission goes horribly wrong. She's lost in space and struggles to try to make her way back to Earth.
Water-ice clouds, polar ice and other geographic features can be seen in this full-disk image of Mars from 2011. NASA's Mars Curiosity Rover touched down on the planet on August 6, 2012. Take a look at stunning photographs of Mars over the years


"Gravity" is just a film. Imagine a similar real-life scenario: Would there be any chance of survival?
That's a concern for the General Authority of Islamic Affairs & Endowments, or GAIAE, the United Arab Emirates' religious watchdog, for anyone who wishes to travel to Mars. The GAIAE has issued a fatwa, or an official Islamic ruling, to warn Muslims against a Mars mission.
So far, the UAE has supported space travel. Abu Dhabi's Aabar Investments teamed up with Richard Branson's Virgin group to create Virgin Galactic to provide spaceflights for tourists, starting this year. But a mission to Mars, it seems, is one step too far.


Tourist trips to the Moon by 2043?
The mission is being planned by the Dutch nonprofit foundation Mars One. In April 2013, it announced its ambitions to establish a human settlement on the Red Planet by 2025.
But the GAIAE likens the journey to a suicide mission. On the authority's free 24-hour hotline, the issue was deliberated by the center's specialized muftis, or scholars, who released the following statement: "It is not permissible to travel to Mars and never to return if there is no life on Mars. The chances of dying are higher than living."
Taking one's life willingly is against Islamic principles.
In response, Mars One issued a statement asking the UAE's Islamic authorities to cancel the fatwa, saying every precaution would be taken to reduce the risk to life. "If we may be so bold: the GAIAE should not analyze the risk as they perceive it today," the statement says. "The GAIAE should assess the potential risk for humans as if an unmanned habitable outpost is ready and waiting on Mars. Only when that outpost is established will human lives be risked in Mars One's plan."
The statement includes a verse from the Quran that "encourages Muslims to go out and see the signs of God's creation in the 'heavens and the earth.' " It goes on to say the first Martian settlers would walk in the footsteps of great Muslim explorers like Ibn Battuta, the 14th century Moroccan journeyman whose travels took him across North Africa, the Middle East and Asia.
Indeed, space travel isn't alien to Muslim culture. There have been Muslim space explorers in the past.
200,000 people apply to live on Mars
The first ever Muslim space tourist was Saudi Arabia's Prince Sultan bin Salman Al-Saud, when he joined the crew of American space shuttle Discovery in 1985. In 2006, Anousheh Ansari became the first Iranian-born woman in space. And to help Muslims observe religious obligations in space, the Malaysian government has been instrumental in setting up guidelines.
In 2006, Malaysia's national space agency Angkasa convened a conference of Islamic scientists and scholars to address the religious obligations of Muslim astronauts. The result was a detailed set of rules called "A Guideline of Performing Ibadah (worship) at the International Space Station (ISS)." It tackles a number of issues, like the number of times a Muslim should observe daily prayers, when a day lasts just 90 minutes in orbit.

Mars One says 1,058 candidates have been shortlisted for the mission, from pool of more than 200,000 applicants around the world. It's not clear how many Muslims are among the candidates, but Mars One says applications came from 107 countries.
Since its inception in 2008, the GAIAE has released nearly 2 million fatwas. The fatwa on the Mars mission is now among them
