This week, scientists at NASA's Jet Propulsion Laboratory are running an experiment simulating a deep ocean hydrothermal vent to test theories about the origins of life.

A new NASA-led study finds that when it comes to combating global warming caused by emissions of ozone-forming chemicals, location matters.

NASA Deputy Administrator Lori Garver announced Wednesday a newly planned addition to the International Space Station that will use the orbiting laboratory to test expandable space habitat technology.

This artist's concept of the Orion Service Module was introduced today. When the Orion spacecraft blasts off atop NASA’s Space Launch System rocket in 2017, attached will be the ESA-provided service module – the powerhouse that fuels and propels the Orion spacecraft. Orion will be the most advanced spacecraft ever designed and carry astronauts farther into space than ever before. It will sustain astronauts during space travel and provide safe re-entry from deep space and emergency abort capability. Orion will be launched by NASA's Space Launch System (SLS), a heavy-lift rocket that will provide an entirely new capability for human exploration beyond low Earth orbit. Designed to be flexible for launching spacecraft for crew and cargo missions, SLS will enable new missions of exploration and expand human presence across the solar system. The service module of the Orion spacecraft will provide support to the crew module from launch through separation prior to atmospheric re-entry. Image Credit: NASA

NASA scientists say 2012 was the ninth warmest of any year since 1880, continuing a long-term trend of rising global temperatures. With the exception of 1988, the nine warmest years in the 132-year record all have occurred since 2000, with 2010 and 2005 ranking as the hottest years on record.

NASA's Space Technology Program is looking for visionary advanced concepts. This year's annual call for NASA's Innovative Advanced Concepts Program (NIAC) is seeking proposals for revolutionary concepts with the potential to transform future aerospace missions. Proposed concepts should enable new missions or significantly improve current approaches to achieve aerospace objectives.

Residents of Beijing and many other cities in China were warned to stay inside in mid-January 2013 as the nation faced one of the worst periods of air quality in recent history. The Chinese government ordered factories to scale back emissions, while hospitals saw spikes of more than 20 to 30 percent in patients complaining of respiratory issues, according to news reports. At the time that this Jan. 14 image was taken by satellite, ground-based sensors at the U.S. Embassy in Beijing reported PM2.5 measurements of 291 micrograms per cubic meter of air. Fine, airborne particulate matter (PM) that is smaller than 2.5 microns (about one thirtieth the width of a human hair) is considered dangerous because it is small enough to enter the passages of the human lungs. Most PM2.5 aerosol particles come from the burning of fossil fuels and biomass (wood fires and agricultural burning). The World Health Organization considers PM2.5 to be safe when it is below 25. Also at the time of the image, the air quality index (AQI) in Beijing was 341. An AQI above 300 is considered hazardous to all humans, not just those with heart or lung ailments. AQI below 50 is considered good. On January 12, the peak of the current air crisis, AQI was 775 the U.S Embassy Beijing Air Quality Monitor—off the U.S. Environmental Protection Agency scale—and PM2.5 was 886 micrograms per cubic meter. › View image comparisons with annotations.
