“THE FAIR Are you ready? It’s here!!
The long-awaited New York World’s Fair, which took four years to create, opens its doors to the first of 70,000,000 expected visitors. Dominated by the Fair’s symbol THE UNISPHERE (which means Peace through understanding) the billion-dollar-baby of Robert Moses covers 646 acres…”
The 1964 New York World’s Fair opened fifty years ago this week, on April 22nd, with the theme of “Man’s Achievements in an Expanding Universe.” If this extended Universal News story leaves you with the impression that the fair was not a runaway success, that’s because it wasn’t. The fair was not sanctioned by the Bureau of International Expositions, and it was sandwiched between the official 1962 Seattle World’s Fair and Expo 67 in Montreal, making it a less compelling draw. The opening day’s unfortunately dreary weather was emblematic of the entire two-season event; total attendance for the fair came in at fifty-one million, yet that fell short of the expected seventy million visitors. You might recognize the Unisphere sculpture and “flying saucer” towers in the still below from the 1997 film Men in Black, where they feature prominently.
NASA plans a robotic mission to search for life on Europa | io9
It looks like it’s finally going to happen, an actual mission to Jupiter’s icy moon Europa — one of the the solar system’s best candidates for hosting alien life.
Yesterday, NASA announced an injection of $17.5 billion from the federal government (down by $1.2 billion from its 2010 peak). Of this, $15 million will be allocated for “pre-formulation” work on a mission to Europa, with plans to make detailed observations from orbit and possibly sample its interior oceans with a robotic probe. Mission details are sparse, but if all goes well, it could be launched by 2025 and arriving in the early 2030s.
This is incredibly exciting. Recent evidence points to a reasonable chance of habitability. Its massive subsurface ocean contains almost twice as much water as found on Earth. The water is kept in liquid state owing to the gravitational forces exerted by Jupiter and the moon’s turbulent global ocean currents. The good news is that a probe may not have to dig very deep to conduct its search for life; the moon’s massive plumes are ejecting water directly onto the surface.
