WASHINGTON, Sept. 14 (Xinhua) -- The U.S. space agency NASA unveiled plans on Wednesday for a deep space rocket to carry astronauts to the moon, Mars and other destinations beyond the International Space Station.The Space Launch System, or SLS, will be designed to carry the Orion Multipurpose Crew Vehicle, as well as important cargo, equipment and science experiments to Earth's orbit and destinations beyond. Additionally, the SLS will serve as a backup for commercial and international partner transportation services to the International Space Station."This launch system will create good-paying American jobs, ensure continued U.S. leadership in space, and inspire millions around the world," NASA Administrator Charles Bolden said in a statement. "President Obama challenged us to be bold and dream big, and that's exactly what we are doing at NASA. While I was proud to fly on the space shuttle, kids today can now dream of one day walking on Mars."The SLS rocket will incorporate technological investments from the Space Shuttle program and the Constellation program in order to take advantage of proven hardware and cutting-edge tooling and manufacturing technology that will significantly reduce development and operations costs.The first developmental flight, or mission, is targeted for the end of 2017, according to NASA.

BEIJING, June 28 (Xinhuanet) -- A truck-sized asteroid passed over the Atlantic Ocean within 7,500 miles of the Earth on Monday, according to NASA's Jet Propulsion Laboratory.The space rock, called asteroid 2011 MD, is the second space rock to zip extremely close to the Earth this year.The asteroid, with latest size estimates ranging from 16 to 66 feet (5 to 20 meters) wide, was discovered just last week on June 22, but there was never any risk of it impacting the Earth, NASA scientists said. That means asteroid 2011 MD would likely be too small to survive the fiery plunge through the Earth's atmosphere, let alone reach the surface, NASA scientists said. Asteroids this size can be expected to buzz Earth with close shaves about once every six years, they added.The space rock flew well below geosynchronous satellites, which orbit 22,236 miles (35,786 km) above the Earth, but well above the 220-mile (354-km) altitude of the International Space Station.There was little chance that the asteroid would hit a satellite because of the vastness of space and relatively small number of satellites, experts said.

BEIJING, Sept. 1 (Xinhua) -- Chinese scientists have decided to reschedule the launch of the Tiangong-1, an unmanned space module, due to the failed launch of an experimental orbiter, a spokesperson with the project said Thursday.The decision to delay the launch was based on the consideration that the carrier rocket Long-March II-F, which would be used for the upcoming launch, belongs to the same series as the malfunctioning one that led to the experimental orbiter SJ-11-04 failing to enter Earth's orbit in August."As the investigation into the malfunction of the rocket Long-March II-C remains underway, it is not clear yet whether the malfunction is linked with the Long-March II-F," the unnamed spokesperson said.Previously, the Long-March II-F was expected to send the 8.5-metric ton Tiangong-1, or "Heavenly Palace 1," into space in the second half of this year to perform the nation's first space-docking procedure.The Tiangong-1 will dock with the unmanned Shenzhou-8 spacecraft, which will be sent into space after the Tiangong-1's launch."The specific launch date for the Tiangong-1 will be set based on the results of the investigation into the malfunctioning rocket," the spokesperson said, adding that the project's teams are currently double-checking every product that will be involved in the space-docking.The Shenzhou-8 spacecraft, the Long March II-F carrier rocket, and the Tiangong-1 have all been transferred to the Jiuquan Satellite Launch Center in northwest China's Gansu Province, the spokesperson said.

HAVANA, Sept. 6 (Xinhua) -- Cuban medical authorities have launched the sales of the world's first therapeutic vaccine against lung cancer, local officials said on Tuesday.The CimaVax-EGF vaccine, as a result of a 25-year research into diseases related to tobacco smoking, has been developed by researchers and scientists at the Center of Molecular Immunology (CIM) in Havana.The active drug ingredient in the vaccine is based on "a protein we all have when cancer is uncontrolled." "The epidermal growth factor is related to all cell proliferation," said Gisela Gonzalez, head researcher of the project."The drug could turn the cancer into a manageable, chronic disease by generating antibodies against the proteins which triggered the uncontrolled cell proliferation," she said.The immunogenic vaccine is appropriate to patients with advanced lung cancer in stages of three and four, showing no positive response to other kinds of treatments such as chemotherapy and radiotherapy, the expert said."It is not possible to prevent the disease but this vaccine improves significantly the status of the critically ill patients," she added.She said the CimaVax-EGF has gone through clinical studies and trials in over 1,000 patients across the island and is currently distributed free of charge in all hospitals of the Caribbean island nation.Gonzalez also said researchers at the CIM planned to use the same principle of the CimaVax-EGF in treating other cancerous tumors such as prostate, uterus and breast cancers.Lung cancer is regarded as one of the world's most serious, common and deadly cancers and is most frequently found among tobacco smokers.According to the World Health Organization, the disease generally kills 5 million people a year, and the figure is expected to rise to as much as 8 million by 2030 unless smoking habits are changed.In Cuba, like many other developing countries across the world, smoking is seen as a status symbol. Lung cancer, killing about 20,000 people a year in the Caribbean country, is considered a serious threat to public health and the leading cause of death in 12 of the country's 15 provinces.
