- Inflatable Habitat Blog
-- Get the cold, hard facts about setting up an inflatable lunar
habitat in Antarctica straight from the frigid fingers of Larry Toups,
habitat lead for NASA's Constellation Program Lunar Surface Systems
Office, as he keeps an online journal of the process during January
- Scientific Balloons Achieve Antarctic Flight Record
-- NASA and the National Science Foundation have achieved a new
milestone in conducting scientific observations from balloons, by
launching and operating three long-duration flights within a single
Antarctic summer. Scientists are using the balloons to investigate the
nature of ultra-high-energy cosmic rays and to search for antimatter.
- NASA Scientists Fly Over Arctic to Study New Year Meteor Shower
-- NASA scientists and astronomers took to the skies at the top of the
world to observe the Quadrantid meteor shower. Scientists believe this
could be the most brilliant meteor shower in 2008 with over 100 visible
meteors per hour at its peak.
- NASA Satellite Reveals Unprecedented View of Mysterious 'Night-Shining' Clouds
-- NASA's Aeronomy of Ice in the Mesosphere satellite has provided the
first global-scale, full-season view of iridescent polar clouds that
form 50 miles above Earth's surface.
- NASA Sees Arctic Ocean Circulation About-Face
-- A team of NASA and university scientists has detected an ongoing
reversal in Arctic Ocean circulation triggered by atmospheric
circulation changes that vary on decade-long time scales. The results
suggest not all the large changes seen in Arctic climate in recent
years are a result of long-term trends associated with global warming.
- NASA Data Reveals 'Average' Ozone Hole in 2007
-- Each year, the ozone hole, or depleted region in Earth's protective
ozone layer over the Antarctic reaches its largest size during a period
in September. Images created from 2007 data reveal the extent of the
hole this year was about average when compared to measurements from the
last few decades.
- NASA Finds Greenland Snow Melting Hit Record High in High Places
-- A new NASA-supported study reports that 2007 marked an overall rise
in the melting trend over the entire Greenland ice sheet and,
remarkably, melting in high-altitude areas was greater than ever at 150
percent more than average.
- 'Remarkable' Drop in Arctic Sea Ice Raises Questions
-- NASA scientists, who have been observing declining Arctic sea ice
cover since the earliest measurements in 1979, are working to
understand a sudden speed-up of sea ice decline and what it means for
the future of Earth's northern polar region.
- NASA Researchers Find Snowmelt in Antarctica Creeping Inland
-- In a new NASA study, researchers using 20 years of data from
space-based sensors have confirmed that Antarctic snow is melting
farther inland from the coast over time, melting at higher altitudes
than ever and increasingly melting on Antarctica's largest ice shelf.
- A Warm South Pole? Yes, on Neptune!
-- An international team of astronomers has discovered that Neptune's
south pole is much hotter than the rest of the planet. They have
published the first temperature maps of the lowest portion of Neptune's
atmosphere, showing that its south pole is enabling methane to escape
out of the deep atmosphere.
