MOSCOW, Sept. 16 (Xinhua) -- A Russian Soyuz space capsule carrying three astronauts returned to the Earth Friday, the Mission Control Center outside Moscow confirmed.The three astronauts, two Russians and one American from the International Space Station (ISS), who were flown back by a Soyuz TMA-21 spacecraft, were in good condition, search and rescue teams on the ground in Kazakhstan said.Russian TV images showed the three ISS crew members being taken out of the space capsule and seated in armchairs with blankets to re-adapt to the Earth's gravity.According to the Cosmonaut Training Center, the astronauts underwent physical examinations immediately after the landing, which included examinations of hearts, lungs and adrenal glands.Seventeen helicopters and planes had waited for the capsule's landing.Helicopters will carry the astronauts from the landing site to the Kazakh city of Karaganda, from where the two Russian cosmonauts Alexander Samokutyayev and Andrei Borisenko will fly back to Moscow later Friday, while NASA astronaut Ronald Garan will leave directly for the United States for post-mission rehabilitation, the Itar-Tass news agency reported.The return of the three crew members was originally scheduled for Sept. 8, but was postponed by a failed launch of the Progress cargo ship on Aug. 24.The three crew members remaining on board the ISS are scheduled to return in mid-November.

HELSINKI, Aug. 21 (Xinhua) -- The Finnish company Spektikor has recently developed a novel type of disposable heart rate indicator, local media reported on Sunday.Different from a conventional heart rate monitor, it is a speed heart rate indicator designed for first aid professionals and specially used in first aids in major accidents, disasters and other crises.According to Spektikor, the product is consisted of a heart rate sensor with two EKG electrodes and a LED indicator, which are connected by a 35-cm-long wire.In operation, the sensor is placed on a patient's chest and the LED indicator is sticked to the patient's cheek. If the heart rate is within the normal range, the LED indicator will flash green with each beat. If the heart rate is dangerously low or high, the light will turn red.The product will help hospital staff speed up their work considerably as it is not necessary to check the pulse manually. In addition to saving time, it will also enhance safety, as the LED indicator can be seen clearly at a glance.The market prospect of the disposable heart rate indicator is quite optimistic as there is a worldwide need for the product.

LOS ANGELES, June 24 (Xinhua) -- Near-Earth asteroid 2011 MD will whip past Earth on June 27, but will not pose any threat, NASA's Jet Propulsion Laboratory (JPL) said on Friday.The asteroid will pass only 12,000 kilometers (7,500 miles) above the Earth's surface at about 9:30 EDT, according to JPL in Pasadena, Los Angeles.This small asteroid, only 5-20 meters in diameter, is in a very Earth-like orbit about the Sun, but an orbital analysis indicates there is no chance it will actually strike Earth on Monday, JPL said.If a rocky asteroid the size of 2011 MD were to enter Earth's atmosphere, it would be expected to burn up high in the atmosphere and cause no damage to Earth's surface, said JPL.The accompanying diagram gives a view of the asteroid's trajectory from the general direction of the Sun. This view indicates that 2011 MD will reach its closest Earth approach point in extreme southern latitudes (in fact over the southern Atlantic Ocean), according to JPL. The incoming trajectory leg passes several thousand kilometers outside the geosynchronous ring of satellites and the outgoing leg passes well inside the ring, JPL said.For a brief time, it may be bright enough to be seen even with a modest-sized telescope.One would expect an object of this size to come this close to Earth about every six years on average.The asteroid was discovered by the LINEAR near-Earth object discovery team observing from Socorro, New Mexico.

BEIJING, July 6 (Xinhua) -- The Ministry of Health has issued a national standard on compound food additives to better regulate the production and use of such additives and ensure food safety.Compound food additives, which are designed to improve food quality or assist in food processing, should be used sparingly in food products, according to the standard the ministry issued Tuesday.Titled the General Rule on Compound Food Additives, the standard stipulates that each of the ingredients used for making compound food additives, which are a mix of two or more single food additives, should meet national standards concerning food safety.No chemical reaction should occur and no new compounds should be generated during the production process of compound food additives, according to the standard.Compound food additives producers should clarify limits of the amounts of harmful substances, such as lead and arsenic, in their products and take measures to control the levels of harmful substances, according to the standard, which will come into effect on Sept. 5 this year.
