Input: Consider Input: (CNN) -- Japan's parliament elected Yoshihiko Noda as the country's new prime minister Tuesday, making him the country's sixth new leader in five years. Noda won 308 out of 476 possible votes. The prime minister-elect will officially take over his new post after a ceremonial endorsement by Japan's emperor, which is expected to happen Wednesday. Ahead of the vote, former Prime Minister Naoto Kan officially submitted his resignation, as did his Cabinet, clearing the way for Noda's election. The Democratic Party of Japan, the country's ruling party, picked Noda as its new leader on Monday. He served as finance minister in Kan's cabinet. In his first speech as party leader, Noda called for party unity to tackle Japan's massive problems. "Running Japan's government is like pushing a giant snowball up a snowy, slippery hill," he said Sunday. "In times like this, we can't say, 'I don't like this person,' or 'I don't like that person.' The snowball will slide down." On Friday, Prime Minister Kan announced that he would resign. His approval rating had tumbled following the devastating March earthquake and tsunami that triggered the worst nuclear crisis since Chernobyl as reactor cores overheated and spewed radioactive material into surrounding areas. An observer of Japan's revolving door of prime ministers said the country's political problems are weighing down one of the world's largest economies. Japanese politicians lack spine and public support, said Keith Henry of the Tokyo-based Asia Strategy, a government policy consulting firm. "They've got to turn the ship around 180 degrees," Henry said. "Until they see an iceberg, they're not going to do it." Japan is facing a massive reconstruction program in the region devastated by the tsunami, an ongoing nuclear energy crisis and unaddressed problems in the economy. Noda, a fiscal conservative, has pledged to raise taxes and would like to privatize state assets. Last week, the credit rating agency Moody's downgraded Japan to an Aa3 rating from Aa2, blaming the country's huge deficit and frequent changes in administration that have prevented the government from implementing long-term economic policies. The CIA World Factbook puts the government debt at more than 200% of the GDP. CNN's Kyung Lah contributed to this report.

Input: Consider Input: (CNN) -- Efforts to rescue a research crew aboard a ship stuck in ice off Antarctica stalled Thursday after sea ice conditions made a key element of the rescue plan risky, Australian maritime officials said. The rescue plan called for a helicopter to ferry the passengers from the MV Akademik Shokalskiy to a Chinese vessel, where they would then board a barge to take them to an Australian icebreaker, the Australian Maritime Safety Authority (AMSA) said in a written statement. But the shifting ice conditions prevented the barge from being able to reach the Chinese vessel, the statement said. "Alternative measures to complete the rescue operation are now being investigated by AMSA and the ships involved," the statement said. The news is the latest chapter in a saga that began Christmas Eve after the Russian-flagged MV Akademik Shokalskiy got stuck in 10 feet of ice. Even if the rescue begins Friday, it will still be weeks before the research team will make it to Hobart, Australia, John Young of the Australian Maritime Safety Authority said. "Mid-January is our best guess," Young told reporters on a conference call. The rescue plan called for the helicopter, which can transport 12 people each trip, to ferry the ship's 52 passengers -- who include the research team and journalists -- to the Chinese icebreaker called the Snow Dragon, or Xue Long, the maritime agency said. The 22 Russian crew members of the Akademik Shokalskiy will stay aboard, it said. The passengers are then to be transported by barge from the Chinese ship to the Australian icebreaker Aurora Australis. That's because the Chinese helicopter can't land on the Australian icebreaker because of load restrictions, and ice conditions make it unsafe to land it next to the ship, AMSA said. "The preferred option is to wait for conditions that will allow the rescue to be completed in a single operation to reduce unnecessary risk," the maritime agency said. The master of the Akademik Shokalskiy has decided to keep the crew members on board until the pack ice eventually breaks up and allows the ship to move again, Young said. The vessel has enough supplies to keep the crew going for "a very long time," he said. Failed rescues . The planned helicopter rescue follows a failed attempt by the Chinese icebreaker, which made it six nautical miles from the trapped vessel before being stopped by the ice. That was followed by an effort by the Australian icebreaker, which was forced Monday to suspend efforts to reach the expedition because of bad weather. The Aurora Australis got within 10 nautical miles of the ship before it turned back. Over the weekend, an effort by the French icebreaker Astrolabe was called off by the maritime agency. In preparation for the helicopter rescue, members of the research team as well as the crew of the Akademik Shokalskiy marked a makeshift helipad on the ice where the helicopter can land. Video clips posted online by the research team showed people, with arms locked, walking to tamp down the snow. "As we understand, the helipad was suitable yesterday and will be suitable today," AMSA's Richard Wallace said. Once the passengers are safely aboard the Aurora Australis, the ship will complete a resupply mission to Casey Station, an Australian base in Antarctica, before making its way to Hobart, the maritime agency said. Viral sensations . The exploits of the research crew have gone viral, thanks in large part to Twitter and YouTube posts by those aboard the stranded vessel. Chris Turney, an Australian professor of climate change at the University of New South Wales, has tweeted photos of the stranded ship, the crew and penguins, who he said -- according to one post on Twitter -- "to check out what's going on." "The group on this ship is incredibly collegiate," said Alok Jha, a science correspondent for The Guardian newspaper, told CNN's Anderson Cooper 360. "There are a lot of skills and things people are sharing with each other." Turney has said there are regular briefings on the status of rescue attempts, and in the meantime, people are doing what they can to keep busy. That includes yoga and Spanish classes, Jha and Turney said. The group even managed to ring in 2014 with good cheer. "We're the A, A, E who have traveled far, having fun doing science in Antarctica!" a dozen or so of them sang in a video posted on YouTube. "Lots of snow and lots of ice, lots of penguins, which are very, very nice! "Really good food and company, but a bloody great shame we are still stuck here! Ice cold, cha cha cha! Ice cold, cha cha cha!" Spirits strong among passengers on ship stuck in Antarctic ice . CNN's Radina Gigova and Jethro Mullen contributed to this report.

Input: Consider Input: Lagos, Nigeria (CNN) -- A month after Nigeria's ruling party ruled he may stand for re-election next year, President Goodluck Jonathan said Wednesday he intends to run. Jonathan said he plans to make a formal declaration about his candidacy Saturday. "In presenting myself for service, I make no pretense that I have a magic wand that will solve all of Nigeria's problems or that I am the most intelligent Nigerian," Jonathan wrote on his Facebook page. "Far from it. What I do promise is this -- if I am elected president in 2011, I will make a covenant with you, the Nigerian people, to always do right by you, to tell you the truth at all times, to carry you along and most importantly to listen to you, fellow citizens in our communities, and also those of you on this page." Jonathan's eligibility was in question until last month, when the Peoples Democratic Party said he could run in an open race with other candidates next year. Under Nigerian "zoning" rules, power must shift to different regions and ethnic groups every eight years. Jonathan -- who is from the Niger Delta, in the south -- was part of the joint ticket of the late President Umaru Yar'Adua, who was from the north. Yar'Adua's death in May, after a long illness, upset the order of the zoning. Yar'Adua was elected in 2007 and his southern replacement threatened to halt the north's turn at holding power. "I know you are tired of empty promises, so I will make only one promise to you today," Jonathan wrote. "The only promise I make to you my friends, fellow citizens and Nigeria, is to promise LESS and deliver MORE if I am elected."
