All pretty impressive stuff given China's manned space programme started less than 10 years ago. My concern is that it's all bought and re-engineered technology from Russia, is all vbetween 40 & 20 years old and as with anything that is reproduced will not be as good as the original. That said I've been impressed how China has taken thing slow and steady rathetr than throwing Taikonauts up at every opportunity. They seem to have a definite plan for progressing towards a permenant space station and moon missions and are sticking to it.”

Despite their nationalist rhetoric, Assa2, the Chinese still lag behind in both experience and capabilities, e.g. launcher power.

Their first space stations will almost certainly be more modest affairs like the earlier Russian Salyut space stations which can be read about here: http://en.wikipedia.org/wiki/Salyut

This is expected to cause a moderate enhancement in the meteor activity. The precise number of meteors is highly uncertain, but estimates suggest a peak level of up to 1 to 10 shooting stars per minute. Unfortunately, only 5 to 20% of these meteors will be visible because of the disturbing light from a nearly full moon, so observers are likely to see only 1 meteor per minute or less. However, the event is of great interest to scientists because it will help them understand how meteor showers form and evolve.”

Should be peaking in the UK between about 8-10pm. Don't think it's the light from the moon that's the problem though - probably going to be rediculously cloudy here. Rained all day.

I watched a recent Megastructures program on Discovery HD about this place the other week. Very interesting although it looks like it's been far from an easy build. Also a shame that the actual flights won't start for several years yet. It's looking like it will be nearly a decade between Branson announcing his plans for VG and any actual paying passengers going up. However the spaceport has a tennant, UP Aerospace, already attached launching micro-satellites so there will be activity (they put James 'Scotty' Doohan's ashes into space).

There'll no doubt have to be a load of testing, more testing and even more testing to ensure the reliability of the vehicles concerned, Assa2, since an early fatal incident could effectively kill off the young space tourism industry.

Soyuz launches probes into space...

...but the really interesting bit is that the Soyuz launcher concerned was launched from Kourou in French Guiana:

Europe's first satellite-navigation spacecraft have been sent into orbit. The two Galileo satellites were launched by a Russian Soyuz rocket from its new base in French Guiana at 07:30 local time (10:30 GMT; 11:30 BST).
http://www.bbc.co.uk/news/science-environment-15372540

Clicking on that link above will show a video of that historic launch of a Russian rocket from South America. It's doubly interesting because it raises some interesting long term possibilities since Soyuz is crew rated for the launch of people into space.

At first glance, this terrestrial development might not seem anything to do with space but the types of technologies that are being developed to explore Lake Ellsworth in Antarctica are going to the similar to what's needed to explore sub-surface ocean worlds like Europa: http://en.wikipedia.org/wiki/Europa_%28moon%29

This may seem like a silly question but is the ISS visible from the UK anytime soon? I remember it was visible a couple of months ago and when I try to look up an accurate sighting online, I don't get much luck.

There's a very good radio programme featuring the real discoverer of pulsars, Dame Jocelyn Bell- Burnell, and it can be heard here: http://www.bbc.co.uk/programmes/b016812j

As a 24-year old PhD student, Jocelyn spotted a tiny smudge on a graph buried within 100 feet of printed data from a radio telescope...Her curiosity about such a tiny detail led to one of the most important discoveries in 20th century astronomy - the discovery of pulsars - those dense cores of collapsed stars.

Unfortunately, the combination of a chauvanistic awards committee and two chauvanist recipients (who remembers them now?) who declined to recognise her great contribution to this discovery meant that she did not get a Nobel Prize which she really did deserve. Nevertheless, Dame Jocelyn has received many honours and awards since then by those other institutions who have fully recognised her great contribution to the science of astronomy.

There are other science documentaries to be found here: http://www.bbc.co.uk/radio4/features...burnell/?nonjs

China completed their first automated docking of two spacecraft yesterday.

http://www.bbc.co.uk/news/science-environment-15562928

A major milestone in their plans for a spacestation by 2020. As earlier discussed, China have ambitious plans for space in the near future as they are launching a rover to the Moon, a Mars mission and continue to build their own GPS satellite network (5 so far).

Well, Mandark, the bad news is that it's a planet killer asteroid of the type that wiped out the dinosausrs but the good news is that it'll miss Earth completely. It's also good that the the great majority of the asteroids that could potentially pose a threat have now had their orbits mapped in detail: http://www.astronomynow.com/news/n1110/01asteroids/

This asteroid will probably be visible in binoculars and could be tracked over successive nights. Not only will some studies be able to be done about its mass, composition, etc. but its orbit can be refined even more so that we'll know precisely where it is.

And now for a news roundup...

China has joined two space vehicles together in orbit for the first time.

The unmanned Shenzhou 8 craft, launched earlier this week, made contact with the Tiangong-1 space lab at 1729 GMT. The union occurred over China itself.
http://www.bbc.co.uk/news/science-environment-15562928

China is perhaps where the USA and Soviets were in the mid-1960s and this docking procedure shows that they are on the way to launching their own modest space station within the next few years.

British scientists and engineers want a piece of the Moon.

They're keen to participate in the European Space Agency's (Esa) Lunar Lander mission which will attempt to put down on the body's southern pole later this decade.
http://www.bbc.co.uk/news/science-environment-15574653

By coincidence, the Moon was also the subject of this week's In Our Time and that good documentary can be listened to here:

Mankind first walked on the Moon in 1969, but it is debatable how important this huge political event was in developing our scientific knowledge. The advances of space science, including data from satellites and the moon landings, have given us some startling insights into the history of our own planet, but many intriguing questions remain unanswered.

It will be around 10th to 11th magnitude on the night of the 8th (tuesday)
Should be possible with big binoculars, if you know where to look
I'll be trying with bins on Tues night, clouds permitting - I'll only be getting a scope out if the bins don't work out.

Wednesday night, it'll be dimmer, but better positioned - though it will gradually head into the skyglow caused by the Moon, making it tougher to see, and then a decent scope will probably be neccesary to pick up YU55.

Tuesday night it'll be low to the West, clinbing through Aquila, but not climbing fast enough to avoid setting around 1am-1:30am.
Though it'll likely be lost among the horizon murk long before midnight.

Wednesday night, it'll be above-right of the Moon - East/SouthEast in Pisces, around 7pm
The bright 'star', below-right of the Moon will be Jupiter btw
By 11pm it'll be to the South, to the right of the Moon, with Jupiter below the Moon

Anyone taking a look with scope or binocs with 15x magnification or more, I'd recommend taking a look at Jupiter while you're on.
The 4 little spots to the right of the planet are it's biggest moons, Io, Callisto, Europa, Ganymede.
Depending what time you look, there may appear to be fewer than 4, but that's because they pass very close to each other at various times through the night.
20x or more, and you should be able to see the main dark cloud belts on Jupiter's surface.

Unfortunately, the reports have been inconsistent in this respect. There was even one I read today that said that asteroid 2005 YU55 would be visible to the naked eye which seemed doubtful given the dark nature of the surface.

Apparently, the Arecibo dish in Puerto Rico will be used to try to radar map the asteroid as it passes.

The US Army's plans for the Moon

It's not very well known, but in 1959, the US Army produced a concept study for a crewed base on the Moon for scientific and military purposes. It was done as there was a perceived threat that the Soviets would get to the Moon first and that this would undermine US prestige and security.

Project Horizon would have been a mammoth undertaking that would have dwarfed Project Apollo if it had ever been followed up. The report can be downloaded from here: http://www.2shared.com/document/NsEX...zonReport.html

Europa really does have a liquid ocean after all

Scientists have found the best evidence yet for water just beneath the surface of Jupiter's icy moon, Europa. Analysis of the moon's surface suggests plumes of warmer water well up beneath its icy shell, melting and fracturing the outer layers. The results, published in the journal Nature, predict that small lakes exist only 3km below the crust.

New Mars rover to be launched on Saturday

The Curiosity rover has 10 science instruments to search for evidence about whether Mars had environments favorable for microbial life, including the chemical ingredients for life. The rover will use a laser to look inside rocks and release their gasses so its spectrometer can analyze and send the data back to Earth. The latest online information on the Mars Science Laboratory mission is at: http://www.nasa.gov/msl . JPL, a division of the California Institute of Technology in Pasadena, manages the mission for NASA.

Can't wait for that probe to go and dive in...
