Πρώτη δοκιμή για το νέο σύστημα δορυφορικών επικοινωνιών της Ευρώπης

Ευρωπαϊκός δορυφόρος μετέδωσε στο έδαφος εικόνες χρησιμοποιώντας για πρώτη φορά ένα σύστημα επικοινωνιών που βασίζεται σε λέιζερ. Το σύστημα EDRS θα μεσολαβεί στις επικοινωνίες των δορυφόρων κέντρα και θα προσφέρει για πρώτη φορά αδιάλειπτη σύνδεση με τα επίγεια κέντρα λήψης.

Οργανικά μόρια εντόπισε το Philae στην επιφάνεια του κομήτη

Μετά την πρώτη ανακοίνωση για τα ευρήματα του Philae που αφορούσαν την «υφή» του κομήτη και το ότι ο 67P είναι πιο σκληρός από όσο ανέμεναν οι επιστήμονες οι επιτελείς της αποστολής ανακοίνωσαν ότι η διαστημοσυσκευή εντόπισε οργανικά μόρια στην επιφάνεια του κομήτη.

Πρώτες εικόνες του Philae να αναπηδά στον κομήτη 67P

Σχεδόν τέσσερις μέρες μετά την πρώτη, ιστορική προσεδάφιση σε κομήτη, η ευρωπαϊκή διαστημική υπηρεσία ESA δημοσιοποίησε εικόνες που δείχνουν το ρομπότ Philae τη στιγμή που αναπηδά για πρώτη φορά στη σκονισμένη επιφάνεια του κομήτη 67P.

Σε κώμα έπεσε ο πρωτοπόρος των κομητών Philae

Η μπαταρία του ρομπότ Philae, που προσεδαφίσθηκε στην επιφάνεια του κομήτη 67P την περασμένη Τετάρτη, σταμάτησε να λειτουργεί, όπως ανέφερε η Ευρωπαϊκή Υπηρεσία Διαστήματος.

Θανάσης Οικονόμου: Ένας Έλληνας πίσω από την αποστολή της Rosetta

Έχει βραβευτεί από τη NASA για την πολύχρονη συνεισφορά του στη διαστημική έρευνα. Θα μπορούσε να χαρακτηριστεί ως «ο γιατρός των πλανητών», αφού δεν υπάρχει σχεδόν καμία διαστημική αποστολή που να μην έχει μεταφέρει και ένα όργανο με την υπογραφή του Θανάση Οικονόμου. Ποιος είναι ο έλληνας επιστήμονας που θα ανιχνεύσει πρώτος τη χημική σύσταση του κομήτη στον οποίο κατευθύνεται η Rosetta...

Mankind Has Landed on a Comet

Mankind Has Landed on a Comet

Over 10 years ago, the Rosetta spacecraft left Earth to begin a long, lonely journey toward a ball of ice and rock. That four billion mile trek finally ended today, capped off with a nail-biting finale where Rosetta's washing-machine-sized lander, Philae, became the first thing we humans have ever landed on a comet. Holy shit.

Rosetta's target is Comet 67P/Churyumov-Gerasimenko, a lumpy ball whose orbit loops between Jupiter and Earth. There's no way to get there in one straight shot, so Rosetta took a long, circuitous path, with four planetary flybys that gave it gravity assists.

The last portion of the journey, where Rosetta orbited Comet 67P itself and let go of its lander Philae, was the most complicated and perilous, threatening to undo all the past decade of careful planning. With both the spacecraft and the comet moving at high speeds, the tiniest error could make Philae miss its landing site. And once Philae was ejected from Rosetta, it was in free fall for seven hours, the so-called "seven hours of terror." A thruster system to push the lander down wasn't working, so Philae could only use its harpoon-like legs to screw itself into the comet. If Philae had landed on too steep of a surface, it would have fallen over with no way to get up.


A simulation of the Philae landing. It pretty much went according to plan!

So why did we spend all this trouble to study a barren piece of rock and ice? Only to answer a question as fundamental as the origin of our solar system. Before the sun and planets formed, our solar system was a cloud of gas and dust called "pre-solar nebulae." Comets are a sort of preserved pre-solar nebulae, a time machine into the early solar system. Philae is equipped with a bevy of instruments to help it study the makeup of Comet 67P's ice and rocks.

The mission from here is slated to last until August 2015, when the comet reaches its closest point to the Sun. Philae will be there as Comet 67P slowly melts into the streak we think of when we think of comets. It's the end of one journey, and the beginning of another.

'Pangu' Jailbreak for iOS 8.x Now Available for Mac, Compatible with Newer Apple Devices

The Pangu development team today updated its jailbreak for iOS 8 and 8.1, bringing full support for the Mac. The update comes a week after the program saw an update for Windows that brought an automatic installation of Cydia and support for the English language.

panguios8
Pangu's jailbreak tool for iOS 8 is the first that is compatible with any device running iOS 8.0 to iOS 8.1, including newer devices such as the iPhone 6, iPhone 6 Plus, iPad Air 2, and iPad mini 3. The jailbreak method allows users to install content like themes, tweaks, and apps from other sources than the App Store. The Pangu development team recommends that users backup their iPhones, iPads, and iPod touches before using the tool, and notes that devices upgraded over-the-air may need to be restored before being jailbroken.

Cydia administrator Jay Freeman noted on his Twitter that the Pangu jailbreak is "stable enough" and said that developers on Cydia are now able to mark their own apps as iOS 8 compatible. Members on our forums are also maintaining an active list of which Cydia apps are compatible with iOS 8 and Pangu's jailbreak, and interested users should look there for more specific information.

Pangu can be downloaded for OS X and Windows as an untethered jailbreak, meaning that users only have to apply the method once. The release of the tool follows an announcement by the Electronic Frontier Foundation yesterday stating that a new petition was filed with the Librarian of Congress to extend an exemption that allows jailbreaking to be legal. The exemption was last renewed in 2012 and created by the U.S. Congress in 2010.

Playing around with a water bubble in space must never get old

Playing around with a water bubble in space must never get old

I'm happy when I see astronauts happy. There's something about seeing people in space enjoy all there is about space that's just infectious. Even the little things, like playing around with a giant water bubble blob. I mean, I would do the same thing they're doing. Let it swallow my hands while a GoPro is inside.

NASA writes:

During Expedition 40 in the summer of 2014, NASA astronauts Steve Swanson and Reid Wiseman — along with European Space Agency astronaut Alexander Gerst — explored the phenomenon of water surface tension in microgravity on the International Space Station. The crew "submerged" a sealed GoPro camera into a floating ball of water the size of a softball and recorded the activity with a 3-D camera.

Spectacular rendering of the solar system to scale

Spectacular rendering of the solar system to scale

I don't know about you, but every time I'm reminded about the huge scale of the universe, I mentally re-evaluate my own life and my relationship with what is around me. This amazing illustration by Roberto Ziche's with the Sun and the planets laying on the floor makes that comparison even more impressive.

You can download the full resolution image here.

The Sun is, obviously, in the background. And in the foreground: Mercury, Venus, Earth and the Moon, Mars, Jupiter, Saturn, Uranus, Neptune and dwarf planets, Pluto, Haumea, Makemake, and Eris.

Σταματά η λιανική διάθεση των Windows 7 και 8

Η Microsoft τερματίζει την πώληση των περισσότερων εκδόσεων των Windows 7, καθώς και των Windows 8, εν αναμονή των Windows 10, που αναμένονται στο τέλος του 2015 και θα «τρέχουν» σε όλες τις συσκευές (επιτραπέζιους και φορητούς υπολογιστές, ταμπλέτες και «έξυπνα» κινητά τηλέφωνα).
