A NASA spacecraft dedicated to measuring carbon dioxide in the atmosphere has achieved final orbit, producing its first science data this week.
According to the longest sleep study ever conducted in space, astronauts’ use of sleeping pills, like ambien, is extremely high. The decade-long study also revealed space-farers are chronically sleep deficient while in orbit, and during the period leading up to blastoff. The study was published in the August issue of The Lancet Neurology. Continue reading
Forty-five years ago today, at 10:56 p.m. EDT, Neil Armstrong took the most famous step of the 20th century. With more than half a billion people watching, the commander of the Apollo 11 climbed down the spacecraft’s ladder and on to the surface of the moon and proclaimed the unforgettable words: “That’s one small step for a man, one giant leap for mankind.” Continue reading
If a tractor full of confetti was launched into the night sky and then beamed with a strobe light, it might look something like the Hubble Space Telescope image above. It is, according to NASA, among the most colorful of … Continue reading
A study released by NASA and others offers the most definitive evidence that parts of the ice sheet in West Antarctica are melting and the damage is irreversible. The collapse will take more than a century, and the melting will lead to rising sea levels. Judy Woodruff talks to Thomas Wagner of NASA, one of the team’s lead members, about the larger consequences of these projections. Continue reading
The resemblance is uncanny, but no, these aren’t Starfleet logos emblazoned on planet Vulcan. Perhaps fittingly, though, this nasa Mars Reconnaissance Orbiter image shows a section of an active dune field on Mars. Strong winds blowing in a single direction resulted in massive piles of basaltic sand about 200 meters wide and 20 meters tall that formed crescent-shaped “barchan dunes.” Continue reading
NASA scientists say the Kepler space telescope may have discovered the most “Earth-like” planet yet. Circling a star about 500 light-years away, planet Kepler 186-F may be the right temperature to allow liquid water to flow on its surface. Hari Sreenivasan talks to Tom Barclay of NASA Ames Research Center about why this discovery is exciting to astronomers. Continue reading
