NASA : NASA and Star Wars: The Connections Are Strong in This One.- NASA y la Guerra de las Galaxias, las conexiones son muy fuertes

Space Screening, ‘TIE’-ins, Tatooine and The Droids You’re Looking For
NASA astronauts “use the force” every time they launch … from a certain point of view. We have real-world droids and ion engines. We’ve seen dual-sun planets like Tatooine and a moon that eerily resembles the Death Star. And with all the excitement around the premiere of Star Wars: The Force Awakens, the Force will soon be felt 250 miles above Earth on the International Space Station. Disney is sending up the new film so the astronauts can watch in orbit, and the station's commander, Scott Kelly, can hardly wait:
If you're looking to be a "sky walker" yourself someday, NASA is now taking astronaut applications and we're offering a list of Star Wars-related reasons you should apply. Recently returned station astronaut Kjell Lindgren is such a fan that he posed with his station crewmates in a Jedi-themed mission poster and talked to StarWars.com about it.  Shortly before leaving the station, Lindgren tweeted about the uncanny resemblance of the station’s cupola to the cockpit of an Imperial TIE Fighter:
That's not the first connection we've noticed. When space shuttle Atlantis left the International Space Station after 2007’s STS-117 mission, it caught a view of the station that looked to some like a TIE fighter giving chase:

The "TIE-ins" go beyond casual resemblance to real engineering. NASA already uses actual ion engines ("TIE" stands for "Twin Ion Engines") on spacecraft like Dawn, currently orbiting the dwarf planet Ceres. In fact, Dawn goes one better with three ion engines. The next generation of this engine is being considered for the Asteroid Redirect Mission, a stepping stone on NASA's Journey to Mars.

We Actually Do Have the Droids You’re Looking For
NASA has robots roving and exploring all over the solar system, but it's our own “R2” that's most likely to resonate with Star Wars fans. Robonaut 2, launched in 2011, is working along side humans on board the International Space Station, and may eventually help with spacewalks too dangerous for humans. Incidentally, an earlier version of Robonaut bore a strong “facial” resemblance to enigmatic bounty hunter Boba Fett.

Another "droid" seen on the space station was directly inspired by the saga. In 1999, then Massachusetts Institute of Technology (MIT) professor David Miller, now NASA's Chief Technologist, showed the original 1977 Star Wars to his students on their first day of class. After the scene where hero Luke Skywalker learns lightsaber skills by sparring with a floating droid “remotes” on the Millennium Falcon, Miller stood up and pointed: "I want you to build me some of those."
The result was "SPHERES," or Synchronized Position Hold, Engage, Reorient, Experimental Satellites.  Originally designed to test spacecraft rendezvous and docking maneuvers, the bowling-ball size mini-satellites can now be powered by smart phones.

We couldn't resist having some fun with SPHERES and other NASA technology by creating a series of social media shareables for Star Wars Day, or "May the Fourth Be With You."


That’s No Moon, It's A ... Oh, Wait, It's Just a Moon
When we send our spacecraft into the solar system and point our telescopes beyond, we often see things that seem taken right out of the Star Wars universe. Saturn’s moon Mimas has become known as the "Death Star" moon because of how its 80-mile wide Herschel crater creates a resemblance to the Imperial battle station, especially when seen in this distant view from Cassini:

Let's all hope that thing hasn't yet become fully operational.
Farther from home, the Hubble Space Telescope has photographed what looks like a cosmic, double-bladed lightsaber in the Orion B molecular cloud complex, located 1,350 light-years away. That's just a short hop once you've fired up the hyperdrive.
 
Artist's concept of the fireworks that accompany the birth of a star
This is an artist's concept of the fireworks that accompany the birth of a star. The young stellar object is encircled by a pancake-shaped disk of dust and gas left over from the collapse of the nebula that formed the star. Gas falls onto the newly forming star and is heated to the point that some of it escapes along the star's spin axis. Intertwined by magnetic fields, the bipolar jets blast into space at over 100,000 miles per hour. As seen from far away, they resemble a double-bladed lightsaber from the Star Wars film series.

It also turns out that some of the fictional planetary creations of the "Star Wars" universe are strikingly similar to real planets in our own Milky Way galaxy.  There's an icy world nicknamed Hoth, a potential water world like Kamino and a stand-in for volcanic Mustafar. The Kepler mission, which has confirmed more than 1,000 planets outside of our solar system, has discovered a world orbiting two suns, much like the fictional Tatooine, where Luke Skywalker stared into that twin sunset dreaming of battling the Empire. Kepler-16b, confirmed in 2011, represented a "milestone discovery," according to Kepler principal investigator William Borucki. "Given that most stars in our galaxy are part of a binary system, this means the opportunities for life are much broader than if planets form only around single stars."

By the way, if we ever visit a planet like Tatooine, we may already know how to build a Jawa Sand Crawler, based on the treads on this crawler-transporter,  which carries rockets to the launchpad in Florida.
No, NASA doesn’t have light sabers or hyperdrive yet. And despite popular demand, we’re not building a Death Star. But we are doing what we've done for over half a century -- sending spacecraft into our solar system and beyond, and peering with our telescopes into galaxies far, far away.
