Rosetta Blog 15 Jul 2014, 14:29 UTC Tweet We’re heading for the final 10,000 km between Rosetta and comet 67P/C-G today, with four of ten rendezvous burns left to complete before arriving on 6 August. Tomorrow’s burn is the third of four so-called ‘Far Approach Trajectory’ (FAT) burns that are being conducted once a week in the period 2–23 July. The burn will get underway on 16 July at 13:36 CEST, and will reduce Rosetta’s speed by 11 m/s relative to the comet. It will take about 26 minutes. The one-way signal travel time between the spacecraft and Earth tomorrow will be 22 minutes 34 seconds. (Ed - we’ll post an update as a comment to this blog entry with the outcome – please allow a little extra time on top for the spacecraft operators to check the data and relay that information to us!) As reported last week, the 9 July burn was successfully completed; lasting 46 minutes 2 seconds, it achieved a change in velocity of 25.7 m/s. Once tomorrow's burn is complete, there is one more ‘FAT’ burn scheduled for 23 July, which will reduce the velocity by 5 m/s; then a pair of “Close Approach Trajectory” (CAT) burns on 3 and 6 August ...
SPACE.com 15 Jul 2014, 13:35 UTC SpaceX managed to fly part of its Falcon 9 rocket back to Earth today (July 14) in a reusability test that did not go entirely as planned. The rocket's first stage performed its re-entry burn and other tasks well but ended up hitting the water hard.
Bad Astronomy 15 Jul 2014, 11:30 UTC You’d think that by now — with dozens of telescopes on, above, and below the ground, observing the skies from all latitudes and longitudes, and having centuries of time in which to work — every object in the sky would be cataloged and understood.But that’s not the case. Not at all. There are still plenty of weird beasties to tease out of the dark, astronomical oddities hiding in plain sight. One of them is G 70.5+1.9, which is way prettier than its catalog-generated name might suggest. Here’s the proof:That gorgeous photo is by my pal Travis Rector, who noticed it at the edge of another nebula he was observing. Travis notes it looks like a Bald Eagle in flight, the bright head to the left, the bluish strands outlining the beak. I have to agree. You can even see a wing above it, the tail behind, the taloned feet below! The prosaic name notwithstanding, I think The Bald Eagle Nebula is a far better moniker for it.Right away I figured it for an old supernova remnant. When a star explodes, a lot of gas is expelled into space at a ferocious clip. It slams into the gas surrounding it, creating ...
SPACE.com 15 Jul 2014, 11:12 UTC While NASA's James Webb Space Telescope will be capable of finding signs of life on nearby exoplanets after its 2018 launch, a bona fide hunt for aliens beyond Earth's neighborhood will require even bigger instruments, experts say.

As the satellite's orbit takes it to the nighttime side of the planet, Landsat 8 pivots to point at the moon. It scans the distant lunar surface multiple times, then flips back around to continue its task of collecting land-cover information of the sunny side of Earth below.read more
