Reflections On Apollo

A video screen telecasting Buzz Aldrin reflected in the helmet of a spacesuit in Washington (ABC News) It’s been 40 years since Apollo 11, something that I’ve known about for as long as I can remember as I was born not that long before it and, apparently, screamed all the way through the landing televised at the hospital. Sorry about that! ๐Ÿ™‚

The fact that the Apollo programme ended so soon after Apollo 11 (Apollo 17 was the last mission, and the only one to carry a scientist, geologist Harrison Schmitt) was already foreshadowed in budget cuts in 1967, which to me seems a great shame given the fact that we were for the first time looking at leaving the cradle of the earth – something that humanity will have to do eventually before the sun dies (assuming we can survive the current issues facing us). I wonder what we would have found on the lunar surface if further Apollo missions had taken more scientists to the moon ? Would we have already explored the craters nearer the poles where we now look for water ice ? Would we have have a permanent base there ? Few people know that NASA had already planned, prior to Armstrong, Aldrin and Collins, longer stays, a lunar flyer to let astronauts visit other areas on the surface and even a base on the moon as part of the Apollo Applications Program, though sadly only Skylab survived the axe to make it into space.

After Apollo 17 it took another 6 years for NASA to get back into space with STS-1, the first shuttle space flight, and we’ve still not been out of earth orbit since 1972, 37 years ago. It would be tragic if we ended up like the original settlers of Easter Island who used up all the resources needed for long distance travel and effectively stranded themselves.

Apollo From Orbit – Images from LRO

NASA’s Lunar Reconnaissance Orbiter (LRO) has returned some initial images from a number of the Apollo landing sites on the moons surface, namely Apollo 11, 14, 15, 16 & 17. My favourite has to be the Apollo 14 image which includes the trails of the astronauts footprints from the LM to a set of scientific instruments.

In case you can’t spot the details, here’s the annotated image.

Don’t forget these images were taken during the commissioning phase of LRO whilst it is in a highly elliptical orbit, NASA believe that once its in its science orbit (roughly 50 miles altitude above the lunar service) the resolution will by around four times greater!

What Price Ideology ? – Mbeki, AIDS and the lost ARV treatment

Reading the New Scientist article on AIDS Deniers (which reminded me a lot of the Global Warming denial farce with its reliance on obsolete results, junk science and people who won’t let facts get in the way of a good conspiracy theory) I was very disturbed read about an assessment on the number of extra deaths in South Africa caused by the policies of its ex-president, Thabo Mbeki. Mbeki did his best to block the use of ART’s in the treatment of AIDS, despite all the evidence that they were the best treatment. The number of extra deaths due to this is simply staggering, around a third of a million lives lost due to the false ideology that HIV doesn’t cause AIDS. ๐Ÿ™

The journal article referenced for those numbers is called “Estimating the Lost Benefits of Antiretroviral Drug Use in South Africa” and is published at the end of last year in Volume 49 – Issue 4 of the JAIDS Journal of Acquired Immune Deficiency Syndromes. The abstract for the paper puts the issue like this:

South Africa is one of the countries most severely affected by HIV/AIDS. At the peak of the epidemic, the government, going against consensus scientific opinion, argued that HIV was not the cause of AIDS and that antiretroviral (ARV) drugs were not useful for patients and declined to accept freely donated nevirapine and grants from the Global Fund.

The cost was truly devastating:

Using modeling, we compared the number of persons who received ARVs for treatment and prevention of mother-to-child HIV transmission between 2000 and 2005 with an alternative of what was reasonably feasible in the country during that period. More than 330,000 lives or approximately 2.2 million person-years were lost because a feasible and timely ARV treatment program was not implemented in South Africa. Thirty-five thousand babies were born with HIV, resulting in 1.6 million person-years lost by not implementing a mother-to-child transmission prophylaxis program using nevirapine. The total lost benefits of ARVs are at least 3.8 million person-years for the period 2000-2005.

What a price to pay. ๐Ÿ™

KDE in Space – Planck Researchers Using Kst

A press release from the University of British Columbia (found via a tweet on the Planck CMB telecopes Twitter feed) talks about their use of the KDE program KST, a real-time large-dataset viewing and plotting tool, chosen because of the amount of data that would be generated:

But the cameras will produce a large amount of scientific data to process–with the LFI instrument alone producing more than 100 Gigabytes a year. Traditional data plotting and analysis packages like MATLAB and IDL wouldn’t cut it.

Both UBC and the University of Toronto have been involved with the development of the KST project, and the Canadian Space Agency has contributed funding to it.

Fingers Crossed.. (updated)

We’ve got Kepler now starting it’s science mission after finishing commissioning, Atlantis at the Hubble Space Telescope for the final repair mission and in just over 1 hour the ESA will launch a single rocket with both the Herschel infra-red space telescope and the Planck CMB telescope. That’s two very expensive satellites sat on top of a rocket with a rather chequered launch history!

Best of luck folks (which is also what the Mars Exploration Rover “Spirit” needs given it’s gotten itself stuck on Mars!)..

Update: So far so good, first and second stages ran and separated OK, third stage running at the moment prior to separation of Herschel and Planck.

Update 2: Third stage burn complete, in ballistic phase.

Update 3: Herschel separated from third stage!

Update 4: The cylinder protecting Planck has been jettisoned.

Update 5: Planck has separated from the third stage!

That’s it for me for tonight, it’s almost midnight here…

Update 6: ESA has established communications with both telescopes and currently they’re both looking good for their journey to L2.

Belle Monte-Carlo Production on the Amazon EC2 Cloud

A few weeks ago Martin Sevior and Tom Ffield of the University of Melbourne did a talk at VPAC called “Belle Monte-Carlo production on the Amazon EC2 cloud” based on a paper they’d presented at the International Conference of Computing in High Energy and Nuclear Physics. The presentation is now available on the VPAC website.

It’s all about testing the cloud computing model via Amazon EC2 for Monte Carlo production for the SuperBelle experiment at the KEK collider in Japan. My favourite comment is that for a real full production run on Amazon EC2 to be useful it would need to be able to return data from S3 to the KEK collider at 600MB/s (~4.7Gb/s) sustained.

I don’t know what Amazon would say to that – well, apart from maybe “no”. ๐Ÿ™‚

NB: This is the talk I mentioned in the comments on Joe Landman’s blog post called “Cloudy Issues“.

Time Team – Friars Wash – Post Excavation Report

Having just watched the first showing of the Time Team Friars Wash dig on the ABC I went searching for any post excavation reports and managed to find one on Scribd written by Wessex Archaeology (where W.A. seem to be putting up a number of reports) which has some interesting follow ups to what’s seen in the program, for instance:

  • It now appears there were likely three temples and an ancillary building, not the four temples talked about (and even then they’re not sure whether the circular building was a temple or a shrine).
  • The lead items thought to be “curses” (lead sheets with writing folded up and deposited at temples) turned out to be, sadly, more likely fishing weights as they were not comparable with previously found “curses”.
  • Whilst they found a lot of coins in Trench 4 (22 all up) calling them a hoard is apparently “tentative”.
  • There are apparently no “direct parallels” of the enamelled broach they found, and it could be 2nd century CE.
  • They found 7 (fragmented) pig jawbones in the sondage through the floor in Trench 1!
  • The closest parallel to the dual temple structure is at Mont de Sene in Burgundy

You can download the PDF of the report if you login to Scribd (they support OpenID, but not OpenID redirections like WP-Yaddis can do to WordPress.com, etc).
