Even more than usual, in the past few weeks the world's eyes have been set on the National Aeronautics and Space Administration, as they've recently launched an astronaut, Scott Kelly, for the first-ever American mission having a man in space for a year - and now, his twin fools NASA!

Over the past few weeks, Food World News has reported the developments of the one-year mission Scott Kelly's just embarked on, as it'll study how his body behaves in space while comparing him to that of his identical twin brother, retired astronaut Mark Kelly's - and on a side note besides this great scientific accomplishment, his twin fools NASA!

According to Yahoo!, news that Scott's twin fools NASA came out a few days before April Fool's, but it's definitely worth the mention in this day, as the whole thing didn't just shock regular people - rather, actual astronauts and rocket scientists!

News24 reports that, seemingly, the only way people at the space office told the twins apart is the fact that Mark has a mustache while Scott remains clean shaven - so, of course, when Mark suddenly shaved off his facial hair and showed up that way at the office, the twin fools NASA.

Even those in the most famous space administration office in the world have their off days, and, of course, as they were embarking on one of the biggest missions they've ever gone through (as the United States has never sent a man to spend such a long time in space), it's no surprise that people in the office were on edge - so the twin fools NASA small prank became effective when, at launch day, Mark walked in clean shaven and Charles Bolden, the NASA administrator, almost had a heart attack when he thought the astronaut hadn't been launched at all.

While news that the twin fools NASA is a great way to start off April Fool's, the mission is incredibly important for space travel, as its results will be used for the later projects of manned missions to Mars.
