Solar eclipse frenzy fuels astronomical tourism in Chile

The total solar eclipse expected in northern Chile early next month is already drawing flocks of visitors eager to glimpse a rare view of the phenomenon through the region's clear skies.

Trump criticizes NASA moon mission after promoting it earlier

U.S. President Donald Trump on Friday criticized NASA for aiming to put astronauts back on the moon by 2024 and urged the space agency to focus instead on "much bigger" initiatives like going to Mars, undercutting his previous support for the lunar initiative. "For all of the money we are spending, NASA should NOT be talking about going to the Moon - We did that 50 years ago," the president wrote on Twitter. "They should be focused on the much bigger things we are doing, including Mars (of which the Moon is a part), Defense and Science!"

Got $50 million for a vacation? NASA to open space station to private citizens

NASA will allow private citizens to stay at the International Space Station (ISS) for month-long getaways at a cost of about $35,000 per night, the U.S. space agency said on Friday. The shift reverses a long-standing prohibition against tourists and private interests at the orbiting research lab, and reflects a broader push to expand commercial activities at the ISS and in space more generally.
