Urban areas are currently responsible for ~70% of the global energy-related carbon dioxide (CO2) emissions, and rapid ongoing global urbanization is increasing the number and size of cities. Thus, understanding city-scale CO2 emissions and how they vary between cities with different urban densities is a critical task. While the relationship …
Cape Canaveral: Confronted with orbiting junk again, Nasa ordered the astronauts aboard the linked space station and shuttle Discovery to move out of the way of a piece of debris on Sunday. Discovery
Two visiting space shuttle astronauts floated outside the ISS on Thursday to hook up a final set of solar panel wings to bring the orbital outpost to full power. Spacewalkers Steven Swanson and Richard Arnold spent six hours outside the station during the first of three spacewalks planned for the …
Vandenberg Air Force Base: A rocket carrying a NASA satellite crashed into the ocean near Antarctica after a failed launch on Tuesday, ending a USD 280 million mission to track global warming from space. The Taurus XL rocket carrying the Orbiting Carbon Observatory blasted off just before 2 am local …
Nasa Spacecraft To Search For Life Outside The Solar System Washington: Nasa is preparing to launch next month the Kepler spacecraft with a new space telescope that for the first time will be capable of detecting Earth-like planets outside our solar system, project managers said. Kepler is scheduled for launch …
conservation Fishing casualties Fishing has dwindled the numbers of the pantropical spotted dolphin, a Pacific Ocean inhabitant, at a worrying rate. Initially the cause was traced to
Sailors, fishermen and cruise passengers should be on the alert. If anybody spots a yellow rubber duck bobbing on the ocean waves, NASA would like to know. The U.S. space agency has yet to find any trace of 90 bathtub toys that were dropped through holes in Greenland
WASHINGTON: More than two trillion tonnes of land ice in Greenland, Antarctica and Alaska have melted since 2003, according to new NASA satellite data that show the latest signs of what scientists say is global warming. More than half of the loss of landlocked ice in the past five years …
A radar instrument aboard a NASA spacecraft has detected large glaciers hidden under rocky debris that may be the vestiges of ice sheets that blanketed parts of Mars in a past ice age, scientists said on Thursday. The glaciers, the biggest known deposits of water on Mars outside of its …
The spacecraft, integrated with its payloads, was tested for three months for communication between instruments and with the ground. ISRO CHANDRAYAAN-1 underwent a series of tests for several weeks at the ISRO Satellite Centre (ISAC), Bangalore. It was broiled at temperatures of above 120 degrees Celsius, subjected to freezing conditions …
An important task for four of the 11 instruments on board Chandrayaan-1 is to look for confirmation of the presence of water-ice in the permanently shadowed regions of the south and north poles of the moon, according to Dr. M.Y.S. Prasad, Associate Director, Satish Dhawan Space Centre, Sriharikota. The conventional …
Astronauts hooked up a water recycling system and installed two new bedrooms aboard the International Space Station on Wednesday while crewmates prepared for a second spacewalk to fix the outpost's power system. The work is part of a final effort to complete the $100 billion orbital complex, a project involving …
marine sciences Rare corals aplenty According to researchers from James Cook University rare coral species might not be at high risks of extinction due to small population sizes.Their tendency to hybridize saves them. The previous prediction was that small population sizes led to decreased genetic diversity, which in turn decreased …
