NASA SPACECRAFT RUNS INTO PROBLEM; CAUSE UNKNOWN BY THE ASSOCIATED PRESS LOS ANGELES — NASA’s Jupiter-bound spacecraft hit a snag Wednesday soon after it used Earth as a gravity slingshot to hurtle toward the outer solar system, but mission managers said it’s on course to arrive at the giant planet in 2016. Juno emerged from Earth’s shadow in safe mode, a state that spacecraft are programmed to go into when there’s some trouble. Despite the problem, “we believe we are on track as planned to Jupiter,” said project manager Rick Nybakken of the NASA Jet Propulsion Laboratory, which manages the $1.1 billion mission. Engineers continued to diagnose the issue, which occurred after Juno whipped around Earth in a momentum-gathering flyby. Up until Wednesday, Juno had been in excellent health. While in safe mode, it can communicate with ground controllers, but its activities are limited. Previous missions to the outer solar system have used Earth as a celestial springboard since there’s no rocket powerful enough to make a direct flight. The Galileo spacecraft buzzed by Earth twice in the 1990s en route to Jupiter, the solar system’s largest planet located 484 million miles from the sun. Launched in 2011, Juno flew beyond the orbit of Mars, Earth’s closest planetary neighbour, before looping back toward our home planet for a quick visit. Wednesday’s rendezvous boosted Juno’s speed from 78,000 mph relative to the sun to 87,000 mph — enough momentum to cruise past the asteroid belt to Jupiter, where it should arrive in 2016. The solar-powered, windmill-shaped spacecraft slipped into Earth’s shadow as planned, but engineers were puzzled by the too little data it sent back afterward. At closest approach, it hurtled 350 miles above the ocean off the coast of South Africa. Since the 1970s, spacecraft have circled or flown past Jupiter including the Voyagers, Pioneers, Galileo, Ulysses, Cassini and, most recently, the New Horizons barrelling toward Pluto. Missions have beamed back stunning views of Jupiter’s trademark Great Red Spot, a raging hurricane-like storm, and its many moons.
Study calculates years when temperatures go off the charts THE ASSOCIATED PRESS Starting in about a decade, Kingston, Jamaica, will probably be off-thecharts hot — permanently. Other places will soon follow. Singapore in 2028. Mexico City in 2031. Cairo in 2036. Phoenix and Honolulu in 2043. And eventually the whole world in 2047. A new study on global warming pinpoints the probable dates for when cities and ecosystems around the world will regularly experience hotter environments the likes of which they have never seen before. And for dozens of cities, mostly in the tropics, those dates are a generation or less away. “This paper is both innovative and sobering,” said Oregon State University professor Jane Lubchenco, former head of the National Oceanic and Atmospheric Administration, who was not involved in the study. To arrive at their projections, the researchers used weather observations, computer models and other data to calculate the point at which every year from then on will be warmer than the hottest year ever recorded over the last 150 years. For example, the world as a whole had its hottest year on record in 2005. The new study,
published Wednesday in the journal Nature, says that by the year 2047, every year that follows will probably be hotter than that record-setting scorcher. Eventually, the coldest year in a particular city or region will be hotter than the hottest year in its past. Study author Camilo Mora and his colleagues said they hope this new way of looking at climate change will spur governments to do something before it is too late. “Now is the time to act,” said another study co-author, Ryan Longman. Mora forecasts that the unprecedented heat starts in 2020 with Manokwa, Indonesia. Then Kingston, Jamaica. Within the next two decades, 59 cities will be living in what is essentially a new climate, including Singapore, Havana, Kuala Lumpur and Mexico City. By 2043, 147 cities — more than half of those studied — will have shifted to a hotter temperature regime. The first U.S. cities to feel that would be Honolulu and Phoenix, followed by San Diego and Orlando, Florida, in 2046. New York and Washington will get new climates around 2047, with Los Angeles, Detroit, Houston, Chicago, Seattle, Austin and Dallas a bit later.
