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 …
China has launched an unmanned spaceship in the latest step towards creating its own manned space station by 2020. The Shenzhou VIII is scheduled to dock with another craft 343km above the earth’s surface later this week, as China practises a key technique first used by the US and Russia …
Russia launched its first unmanned space flight to supply the International Space Station Sunday since an August crash left a half-sized crew on the orbital outpost and raised concerns over Moscow's role as the sole space flight provider. The Progress freighter blasted off from the Baikonur Cosmodrome in Kazakhstan as …
The U.S. space agency on Friday launched a first-of-its kind satellite that will send back data on weather and climate to help forecasters predict major storms and other changes in the environment. “Liftoff of the Delta II with the NPP satellite, blazing the way in new technology for climate research …
Evidence of liquid water on Mars was also found in 2006. How is the latest finding different? There are a lot of gullies on the crater walls of Mars. Occasionally we see (by comparing images taken at different times) that some material has flowed down these gullies. The paper in …
After the six-tonne UARS satellite of Nasa that crashed into the Pacific ocean over a week ago, another is approaching fast for a fiery death plunge soon. This time, it's a defunct German space telescope called ROSAT, which is set to hit the planet at the end of October or …
Sending satellites to monitor the atmosphere is fundamental to weather and climate research. So why is the United States making such a meal of it? (Editorial)
CAPE CANAVERAL, FLORIDA: A six ton Nasa science satellite crashed to Earth on Saturday, leaving a mystery about where a ton of space debris may have landed. The US space agency said it believes the debris ended up in the Pacific Ocean, but the precise time of the bus-sized satellite's …
A six-and-a-half tonne defunct climate satellite that has been circling the Earth for the past 20 years will make a fiery death plunge this week, NASA officials have warned. According to NASA’s latest projections, the bus-size Upper Atmosphere Research Satellite (UARS) will likely plummet down to Earth sometime around Friday …
Sometimes the orange sun rises first. Sometimes it is the red one, although they are never far apart in the sky and you can see them moving around each other, casting double shadows across the firmament and periodically crossing right in front of each other. Such is life, if it …
Washington: To soar far away from Earth and even on to Mars, Nasa has dreamed up the world’s most powerful rocket, a behemoth that borrows from the workhorse liquid-fuel rockets that sent Apollo missions into space four decades ago. But with a price tag that some estimate at $35 billion, …
From double sunrise to double sunset the show goes on, always changing. Sometimes the orange sun rises first. Sometimes it is the red one, although they are never far apart in the sky and you can see them moving around each other, casting double shadows across the firmament and periodically …
NASA unveiled plans on Wednesday for a mammoth deep-space rocket to carry astronauts to the moon, Mars and other destinations beyond the International Space Station. The rocket project would cost $10 billion through 2017, when the first test flight of the Space Launch System is scheduled to take place from …
The design for NASA’s newest behemoth of a rocket harkens back to the giant workhorse liquid rockets that propelled men to the moon. But this time the destinations will be much farther and the rocket even more powerful. The Obama administration today unveiled its much-delayed general plans for its rocket …
The Milky Way abounds with low-mass planets, including small, rocky ones such as Earth. That's the main conclusion of a team of European astronomers, based on their latest haul of extrasolar planets. The new discoveries—55 new planets, including 19 "super-Earths"—were presented here today at the Extreme Solar Systems II conference …
Washington: A spacecraft circling the moon has snapped the sharpest photos ever of the tracks and trash left behind by Apollo astronauts in their visits from 1969 to 1972. Images taken by Nasa’s Lunar Reconnaissance Orbiter from 13 to 15 miles up show the astronauts’ paths when they walked on …
More than 100 spacecraft have been to the moon, including six with U.S. astronauts, but one key piece of information about Earth's natural satellite is still missing -- what's inside. Learning about the interior of the moon is the primary goal of a new NASA mission called Gravity Recovery and …
Capa Canaveral: Four decades after landing men on the moon, Nasa is returning to Earth’s orbiting companion, this time with a set of robotic twins that will measure lunar gravity while chasing one another in circles. By creating the most precise lunar gravity map ever, scientists hope to figure out …
NASA's Mars rover Opportunity is uncovering new details about the role water may have played on what is now a cold, dry planet, scientists said on Thursday. Opportunity is one of two small rovers that landed on opposite sides of Mars in January 2004 for what were expected to be …
The amount of debris orbiting the Earth has reached "a tipping point" for collisions, which would in turn generate more of the debris that threatens astronauts and satellites, according to a U.S. study released on Thursday. NASA needs a new strategic plan for mitigating the hazards posed by spent rocket …
Two Delhi students have made history by discovering an asteroid as part of a unique astronomy project connected to US space agency NASA. The duo will also get an opportunity to name the asteroid. Vaibhav Sapra and Sharanjeet Singh, class XII students of Bal Bharati Public School in Pitampura, discovered …
