Weather forecasts have improved significantly — roughly one day per decade — since the first numerical, physics-based computer models were implemented in the 1950s. What is needed to continue improving our forecasts?
Rosetta crashed onto the surface of a comet on Sept. 30, bringing its mission to an end, though the scientific analysis and discoveries will continue for decades. We examine a few of the biggest surprises and highlights of Rosetta’s scientific journey so far.
All of the names associated with the Rosetta mission, including the orbiter itself, the lander and all of the place names coined by mission scientists on 67P, refer to ancient Egyptian sites or deities, in homage to the Egyptian origin of the Rosetta Stone and Philae obelisk.
Rosetta’s Philae lander made the first landing on the surface of a comet when it touched down on Nov. 12, 2014, three months after Rosetta began orbiting 67P. The landing, though historic, did not go as planned, and Philae was unable to accomplish much of the scientific program that had been scheduled for its 10 instruments.
Guatemala is home to 22 volcanoes, several of which visitors can climb. The most popular is the active Volcán Pacaya; the hike is relatively easy, the views spectacular, and visitors can roast marshmallows near the summit.
Today’s technologies — from smartphones to laptops to smart appliances to cloud computing — require tremendous amounts of water, some of which is needed to cool large heat-generating data centers. Some of the biggest names in tech, along with government agencies and smaller businesses, are taking innovative approaches to deal with water issues — including placing facilities in the high desert.
Northern Vietnam has two international airports, Hanoi and Da Nang. Hanoi’s Noi Bai International Airport is the main gateway, offering service to most major Asian cities, including Hong Kong, Bangkok and Tokyo, but no direct service to the U.S. The airport is located 30 kilometers north of the city center and is best accessed by taxi. Many Hanoi hotels will arrange airport pickup or dropoff for you.
