Star Cluster, Spiral Galaxy, Supernova


A cosmic snapshot from May 19, this colorful telescopic field of view spans about 1 degree or 2 full moons on the sky. Spiky in appearance, foreground Milky Way stars are scattered toward the royal constellation Cepheus while stars of open cluster NGC 6939 gather about 5 thousand light-years in the distance near the top of the frame. Face-on spiral galaxy NGC 6946 is toward the lower left nearly 22 million light-years away. The helpful red lines identify recently discovered supernova SN 2017eaw, the death explosion of a massive star nestled in the galaxy's bluish spiral arms. In fact in the last 100 years, 10 supernovae have been discovered in NGC 6946. By comparison, the average rate of supernovae in our Milky Way is about 1 every 100 years or so. Of course, NGC 6946 is also known as The Fireworks Galaxy. via NASA http://ift.tt/2qjJIDn

May 24, 1962 - Scott Carpenter on the Way to Mercury-Atlas 7 Launch Site


Astronaut Scott Carpenter walks to the launch site to begin the Mercury-Atlas 7 (MA-7) mission on May 24, 1962. Carpenter's Aurora 7 capsule lifted off aboard an Atlas rocket from Cape Canaveral, Florida, at 7:45 a.m. EST, May 24. Carpenter was the fourth American in space and second American to orbit Earth. via NASA http://ift.tt/2qQ7tq9

DARPA Picks Boeing's Phantom Express

Boeing, DARPA to Design, Build, Test New Experimental Spaceplane

"Boeing will develop an autonomous, reusable spaceplane capable of carrying and deploying a small expendable upper stage to launch small (3,000 pound/1,361 kg) satellites into low Earth orbit. Boeing and DARPA will jointly invest in the development. Once the spaceplane - called Phantom Express - reaches the edge of space, it would deploy the second stage and return to Earth. It would then land on a runway to be prepared for its next flight by applying operation and maintenance principles similar to modern aircraft."

Aerojet Rocketdyne Selected As Main Propulsion Provider for Boeing and DARPA Experimental Spaceplane

ISS Daily Summary Report – 5/23/2017

External (EXT) Multiplexer/Demultiplexer (MDM)-1 R&R Extravehicular Activity (EVA):  With IV support from Thomas Pesquet, today Peggy Whitson (EV1) and Jack Fischer (EV2) performed a 2 hour 46 minute EVA to Remove & Replace (R&R) the EXT MDM-1 that failed on Saturday, May 20th. While Whitson performed the EXT MDM R&R, Fischer installed the Lab Nadir External Wireless Communications (EWC) Antennas that were deferred from the last EVA. Solar Array Battery 3A1 Temperatures – On 5/22/17, Battery 3A1 average temperatures peaked above 25°C for three concurrent orbits due to high solar beta, with a maximum average temperature peak of 25.6°C.  Per Flight Rule, ground controllers terminated the use of the battery string by turning the Battery Charge Discharge Unit (BCDU) 3A1 converter off and commanding the Fault Isolator (FI) open.  There is no impact to downstream loads in this configuration Today’s Planned Activities All activities were completed unless otherwise noted.

NGC 4565: Galaxy on Edge


Is our Galaxy this thin? We believe so. Magnificent spiral galaxy NGC 4565 is viewed edge-on from planet Earth. Also known as the Needle Galaxy for its narrow profile, bright NGC 4565 is a stop on many telescopic tours of the northern sky, in the faint but well-groomed constellation Coma Berenices. This sharp, colorful image reveals the galaxy's bulging central core cut by obscuring dust lanes that lace NGC 4565's thin galactic plane. An assortment of other background galaxies is included in the pretty field of view, with neighboring galaxy NGC 4562 at the upper left. NGC 4565 itself lies about 40 million light-years distant and spans some 100,000 light-years. Easily spotted with small telescopes, sky enthusiasts consider NGC 4565 to be a prominent celestial masterpiece Messier missed. via NASA http://ift.tt/2qS4ZWw

Cutting NASA Education In Order To Save It

Keith's note: This is kind of strange. If the intent for the NASA Education Office was to do something "NASA-wide" then you'd think that an agency-wide organization/approach would be needed for that. This is what the NASA Education Office has done for decades. But instead of thinking agency-wide and fixing the NASA Education Office they have decided to close the agency-wide Education Office and shove the remnants inside of the Science Mission Directorate. When I asked Acting NASA CFO Hunter about this he said that NASA does not have a response to this issue and that Acting Education Office AA Mike Kincaid is working on that. So, in other words, they are shutting down the Education Office - without any plan to do all of what the Education Office has been doing for several generations. Hunter and (earlier today) Robert Lightfoot both went off on the whole "inspring the next generation" thing and rambled on about websites and social media - most of which is not paid for by NASA Education office but rather by NASA PAO or the mission directorates. Yet somehow we are supposed to think that doing less education stuff can actually result in more inspiring of the next generation. But oh wait: Hunter thinks Congress will add things back. So why delete things in the first place if you expect them to be put back?
