NASA Sends New Research on Orbital ATK Mission to Space Station

Astronauts soon will have new experiments to conduct related to emergency navigation, DNA sequencing and ultra-cold atom research when the research arrives at the International Space Station following the 4:44 a.m. EDT Monday launch of an Orbital ATK Cygnus spacecraft.

Jupiter Cloud Animation from Juno

How do Jupiter’s clouds move? To help find out, images taken with NASA’s Juno spacecraft during its last pass near Jupiter have been analyzed and digitally extrapolated into a time-lapse video. The eight-second time-lapse video, digitally extrapolated between two images taken only nine minutes apart, estimates how Jupiter’s clouds move over 29 hours. Abstractly, the result appears something like a psychedelic paisley dream. Scientifically, however, the computer animation shows that circular storms tend to swirl, while bands and zones appear to flow. This overall motion is not surprising and has been seen on time-lapse videos of Jupiter before, although never in this detail. The featured region spans about four times the area of Jupiter’s Great Red Spot. Results from Juno are showing, unexpectedly, that Jupiter’s weather phenomena can extend deep below its cloud tops. via NASA https://ift.tt/2GAdjka

Orbital ATK Rocket Rolls Out for May 21 Launch

An Orbital ATK rocket rolls out to launch Pad-0A at NASA’s Wallops Flight Facility on May 17, 2018, in advance of a May 21 launch from Wallops Island, VA. The Antares will launch a Cygnus spacecraft on a cargo resupply mission to the International Space Station. via NASA https://ift.tt/2k8bPor

Dodging powerful laser beams, a drone captured this stunning aerial view. The confrontation took place above the 8.2 meter diameter Very Large Telescopes of the Paranal Observatory on planet Earth. Firing during a test of the observatory’s 4 Laser Guide Star Facility, the lasers are ultimately battling against the blurring effect of atmospheric turbulence by creating artificial guide stars. The guide stars are actually emission from laser excited sodium atoms at high altitudes within the telescopic field of view. Guide star image fluctuations are used in real-time to correct for atmospheric blurring by controlling a deformable mirror in the telescope’s optical path. Known as adaptive optics, the technique can produce images at the diffraction limit of the telescope. That’s the same sharpness you would get if the telescope were in space. via NASA https://ift.tt/2IuA1vD
