An excellent launch, just wish I was around to watch it live. This was the fifth and last ATV (Automated Transfer Vehicle) going to the ISS.
ESA has the tradition of naming the vehicles and this one is named Georges Lemaître. Lemaitre was the first to postulate the the Big Bang theory and much more, check out the link.
lifted off at 23:47 GMT on 29 July (01:47 CEST 30 July, 20:47 local time 29 July) on an Ariane 5 ES rocket.
The vehicle will deliver 6561 kg of freight, including 2628 kg of dry cargo and 3933 kg of water, propellants and gases.

ATV Georges Lemaître is due to dock with the Station on 12 August and will remain attached for up to six months before leaving with waste material for destruction along with the spaceship during atmospheric reentry.
Very nice! Little wonder this was on NASA’s Image of the Day below is the caption from that page if you’re in a hurry:
On July 26, 2014, from 10:57 a.m. to 11:42 a.m. EDT, the moon crossed between NASA’s Solar Dynamics Observatory (SDO) and the sun, a phenomenon called a lunar transit. A lunar transit happens approximately twice a year, causing a partial solar eclipse that can only be seen from SDO’s point of view. Images of the eclipse show a crisp lunar horizon, because the moon has no atmosphere that would distort light. This image shows the blended result of two SDO wavelengths – one in 304 wavelength and another in 171 wavelength.
Possibly the best image ever of the Saturn moon Enceladus, well in my opinion. Be sure to click the image above for a larger version. This image looks towards the Baghdad and Damascus area of the moon. Here’s an annotated version.
From the Cassini website:
Scientists using mission data from NASA’s Cassini spacecraft have identified 101 distinct geysers erupting on Saturn’s icy moon Enceladus. Their analysis suggests it is possible for liquid water to reach from the moon’s underground sea all the way to its surface.
I was looking all over for a graphic on the Mars encounter last Thursday and NASA published this on Friday. Great timing! So now I need to figure out if the comet might be visible with a telescope. Could be, the moon won’t be a factor and Mars should be visible for a time after sunset. I just need to upload the ephemeris for Siding Spring into Stellarium.
One thing I will be able to see (and so will you) on that night is Venus and Spica very close together — easy to see too. More about that later on.
NASA on the visit:
NASA is taking steps to protect its Mars orbiters, while preserving opportunities to gather valuable scientific data, as Comet C/2013 A1 Siding Spring heads toward a close flyby of Mars on Oct. 19.
The comet’s nucleus will miss Mars by about 82,000 miles (132,000 kilometers), shedding material hurtling at about 35 miles (56 kilometers) per second, relative to Mars and Mars-orbiting spacecraft. At that velocity, even the smallest particle — estimated to be about one-fiftieth of an inch (half a millimeter) across — could cause significant damage to a spacecraft.
ESA is getting ready to launch the Intermediate eXperimental Vehicle or IXV. This will test technologies and critical systems for Europe’s autonomous reentry for return missions from low Earth orbit. The IXV is said to be about the size of a car being 5 m long, 1.5 m high, 2.2 m wide and weighs almost 2 tons.
The IXV is to be launched atop a Vega rocket from the Europe’s Spaceport (French Guiana) in November. The flight will collect an immense amount of data during the 1 hour and 40 minute flight to the Pacific Ocean.
The flight will be short in duration and will have HUGE implications for ESA’s ambition of autonomous reentry and the possibilities that will present not to mention a U.K. Spaceport.
The UK is considering to open a spaceport and do it by 2018. The idea is for the UK to become a leader in the growing space market.
Business Secretary Vince Cable:
“Space is big business for the UK. It already contributes £11.3 billion to the economy each year, supporting nearly 35,000 jobs. That’s why it’s important for us to prepare the UK for new launcher technology and take steps towards meeting our ambition of establishing the first British spaceport by 2018.”
Exploring the opportunities that commercial spaceflight presents, and potentially making strategic investments in this area, will support the growth of this thriving industry and underpin the economy of tomorrow, making the UK the place for space
He and the government are very likely correct, a spaceport will provide a focal point for investment, provided they can get established early on and now is the time.
So how do they plan on getting a spaceport up and running by 2018? It won’t be as difficult as you might expect because existing facilities can be adapted. A recent civil Aviation Authority report named eight existing airfields that might be able to host an spaceport and not just any place will do because in addition to meteorological, environmental and economic criteria a few physical factors come into play:
– an existing runway which is, or is capable of being extended to, over 3000 metres in length
– the ability to accommodate dedicated segregated airspace to manage spaceflights safely
– a reasonable distance from densely populated areas in order to minimise impact on the uninvolved general public
This image shows NGC 121, a globular cluster in the constellation of Tucana (The Toucan). Globular clusters are big balls of old stars that orbit the centers of their galaxies like satellites — the Milky Way, for example, has around 150.
NGC 121 belongs to one of our neighboring galaxies, the Small Magellanic Cloud (SMC). It was discovered in 1835 by English astronomer John Herschel, and in recent years it has been studied in detail by astronomers wishing to learn more about how stars form and evolve. Continue reading →
Cassini treats us to a view we would otherwise not get, a crescent Saturn. The view is from the unilluminated side of the rings and was taken in green light.
The angle us just right at 43 degrees below the ringplane so the rings don’t appear to interrupt the crescent. You may notice the “dark” area outside the crescent is faintly illuminated and that is from “ringshine”.
What happened to half of Saturn? Nothing other than Earth’s Moon getting in the way. As pictured above on the far right, Saturn is partly eclipsed by a dark edge of a Moon itself only partly illuminated by the Sun. This year the orbits of the Moon and Saturn have led to an unusually high number of alignments of the ringed giant behind Earth’s largest satellite. Technically termed an occultation, the above image captured one such photogenic juxtaposition from Buenos Aires, Argentina that occurred early last week. Visible to the unaided eye but best viewed with binoculars, there are still four more eclipses of Saturn by our Moon left in 2014. The next one will be on August 4 and visible from Australia, while the one after will occur on August 31 and be visible from western Africa at night but simultaneously from much of eastern North America during the day.
