It’s been a momentous couple of days in the history of Australian space exploration. Just yesterday, the newest antenna in NASA’s Deep Space Network was officially commissioned at our Canberra Deep Space Communication Complex, five years to the day from its original ground breaking ceremony.
The new dish, Deep Space Station 35, incorporates the latest in Beam Waveguide technology: increasing its sensitivity and capacity for tracking, commanding and receiving data from spacecraft located billions of kilometres away across the Solar System.
The Canberra Complex is one of three Deep Space Network stations capable of providing two-way radio contact with robotic deep space missions. The Complex’s sister stations are located in California and Spain. Together, the three stations provide around-the-clock contact with over 35 spacecraft exploring the solar system and beyond. You may remember this technology being utilised recently for the Rosetta and Philae comet landing; and for communicating with the ever so far-flung New Horizons spacecraft on its journey past Pluto.
As a vital communication station for these types of missions, the new antenna will make deep space communication for spacecraft and their Earth-bound support staff even easier.
But don’t put away the space candles just yet. For today marks the 55 anniversary of the signing of the original space communication and tracking agreement signed between Australia and the United States, way back on the 26th February 1960.
It is a partnership that has that has led to many historic firsts and breakthrough discoveries – the first flybys of Mercury and Venus, the vital communication link and television coverage of the first Moonwalk, robotic rover landings on (and amazing views from) the surface of Mars, the first ‘close-ups’ of the giant outer planets and first-time encounters with worlds such as Pluto.
So, we say welcome to the newest addition to the Deep Space Network and happy birthday to our space-relationship with the US. Here’s to another fifty five years of success!
P.S. We couldn’t finish the blog without including this little gem:
Heart rhythm disease is a life-threatening, electrical disorder that stops the heart from pumping blood effectively. It is a lethal condition that is responsible for around 12 per cent of Australian deaths each year.
In order to open the door to better diagnosis and treatment for heart rhythm disease, we’ve been working with the Victor Chang Cardiac Research Institute to develop our very own ‘virtual heart’. What’s more, we’ve done this using the same technology that drives your favourite computer games.
Impressively, when we ran a simulation through the virtual heart, it was able to model hundreds of thousands of different heart beats. This then allowed scientists to screen all of those heart beats, and search for abnormalities.
According to the Victor Chang Institute’s Dr Adam Hill who led the research, this has taken us a step closer to understanding rhythm disturbances in our most vital muscle.
“This research is hugely exciting! We were able to identify why some patients have abnormal ECG signals, and how a person’s genetic background can affect the severity of their disease,” he says.
Analysis on this scale has simply never been possible before. The simulation took just ten days, thanks to the computational grunt of CSIRO’s Bragg supercomputer cluster, which combines traditional CPUs with more powerful graphics processing units or GPUs.
GPUs have typically been used to render complex graphics in computer games. However they can also be used to accelerate scientific computing by multi-tasking on hundreds of computing cores.
By comparison, if you were to try to do the same simulation using a standard desktop PC, it would take 21 years to get the job done.
Adam hopes the new technology will help doctors read ECGs more accurately, which will mean faster, more accurate diagnosis of heart rhythm disease. By understanding why the same disorder affects people differently, the right treatment can be given to the right patients.
Scientists at the Victor Chang Institute are now using these discoveries to develop automatic computerised tools for diagnosing heart rhythm disorders.

Ever heard of the Lizard Squad? They’re an online group that’s claimed to have hacked some pretty large and well-known web identities in recent times. As well as attacks on the Sony, Microsoft and Facebook networks, they’re even alleged to have gained access to Taylor Swift’s Twitter account.
Surely that’s enough to get alarm bells ringing!? But in all seriousness, these sort of attacks are becoming a global concern as our interaction on all levels moves increasingly online. Keeping data private is of the utmost importance. That’s why we’ve been working with global software giant IBM and other partners through the AU2EU project to strengthen how we can protect our own data and improve collaboration in secure environments.
One of the technologies we’re using is IBM’s new Identity Mixer software. Identity Mixer uses cryptographic algorithms to encrypt profile information like age, nationality, personal address and credit card details. By keeping this data hidden from websites and only revealing the most relevant information, we get to hold onto our data, rather than constantly handing it over when we collaborate online.
Identity Mixer will allow our scientists to securely authenticate who they are, and share sensitive data with experts and our partners. For example, in the event that there is a biosecurity issue, it is imperative that this team can freely share data and collaborate with partners and other labs in instances when the lab is locked down, or if the threat requires a rapid response.
Identity Mixer will improve our ability to securely respond to these issues. This is all part of an emergency response plan we have developed with the Australian Government to maintain our agricultural disease free status. In order to deal with these threats it is important to bring together academic, government and research together swiftly and securely to deal with issues.
Adding another level of security, to ensure that this plan can be actioned, is a great outcome for our biosecurity teams.
Looking ahead, Identity Mixer could be really useful for the individual web user. When we are exchanging information online, there is only certain data any websites or vendor really needs. Identity Mixer will only share the relevant data and keep the rest locked away – think of it like a sober friend stopping you from declaring your deepest feelings for a close friend, after you have had one to many bottles of wine.
It doesn’t matter who you are – from the single user, paying bills online to a massive multi-national corporations – securing data and protecting our privacy is vital. Especially when you have national treasures as important as our awesome database of insects – who else is going to protect the arthropods? Check out this video, which runs through some interesting scenarios to help you understand better how the technology works:
…A good night’s sleep, a good night sleep.
Sing it with us now, snorers and snorer sufferers of Australia! Because we might be able to help.
Sleep apnoea is just, well, horrible. It’s a condition where the air passage in the throat becomes blocked during sleep and causes people to stop breathing. Ask any of the million or so Australians who suffer from it – or their sleeping partners – and they will tell you it can cause massive damage: not only physically but emotionally.
Severe cases experience hundreds of blockages per night, leading to high blood pressure, stroke, irregular heartbeats, heart attacks and diabetes. Bed partners are affected too, with their chances of getting a good sleep rendered near impossible. It can lead to relationship breakdowns, and worse.
Thankfully, a new CSIRO-made solution may just offer a Christmas miracle: a 3D-printed titanium mouthguard that helps air flow freely for sufferers while they’re sleeping.
Brisbane-based dentist Chris Hart first had the idea for a mouthguard with airways that would assist airflow past the sleep apnoea sufferer’s soft palate. He approached us for help developing a device 3D-printed from titanium, with a soft medical grade plastic mouthguard.
The result is the Oventus Clearway Device. It’s essentially a ‘duckbill’ which extends from the mouth like a whistle and divides into two separate airways. This allows air to flow through to the back of the throat, bypassing obstructions that cause the problems.
For Gold Coast retiree and sleep apnoea sufferer Maurice Hrovat, 57, the new device – which he was lucky enough to trial – has been not just sleep-changing but life-changing. Hrovat was, in an apparently massive understatement, “quite a good snorer”, and had long ago been banished from his and his wife’s bed, to sleep down the hallway.
Hrovat reported immediate benefits from his trial of the device. “I used to need an afternoon nap, I was so exhausted from a bad night’s sleep,” Hrovat says, but they’re now a thing of the past. “I find I am getting up earlier, and exercising more.” And, most importantly, he’s been allowed back into the bedroom.
The Clearway Device is initially only available through the Turbot Street, Brisbane practice of Chris Hart. With practices in Sydney and Melbourne not introducing the product until the New Year, Santa might have to save your device until Christmas 2015. However, interested patients – or dental or medical practices – can find more information on the Oventus website.
NB: Pricing for the device is around $1500 but depends on the patient’s individual requirements, as well as their healthcare funding and insurance cover.

“’Twas the night before Christmas, when all thro’ the house
Not a creature was stirring, not even a mouse …”
CSIRO scientists are keeping their eyes peeled for more than just Santa Claus this Christmas. With unusually high numbers of mouse sightings in Victoria this spring, CSIRO ecologist Peter Brown and colleagues at various Australian and New Zealand research agencies are monitoring mouse populations to see whether 2015 will bring a sigh of relief or send people scurrying for cover under a deluge of tiny, furry bodies.
While taken individually, mice can be rather cute (think Mickey, Mighty and Danger), en masse they can be absolutely devastating. In 1993, Australia’s worst ever mouse plague caused an estimated $96 million worth of damage, destroyed thousands of hectares of crops, blighted piggeries and ravaged poultry farms. The whiskered marauders chewed their way through rubber and electrical insulation, damaged farm vehicles, ruined cars and buildings. Another plague in 2010/11 was almost as bad, affecting 3 million ha of crops in NSW’s central west and the Riverina, as well as parts of Victoria and South Australia.
Along with economic hardship and disease, plagues bring severe psychological distress for people living through them.
“The sheer stress of dealing with mice in your kitchen every night takes its toll,” Peter says. “They’re everywhere: chewing, defecating, breeding.”
The good news is that with sufficient warning it is possible to prepare for mouse plagues, and to minimise the damage they cause, through early baiting and removing food supplies and cover. Over the years, our scientists have become increasingly accurate at predicting mouse plagues (they got it right in 1994 and 2001-2003) and have developed an ever more sophisticated range of tools to assist them. The latest weapon in their arsenal is “MouseAlert“, a citizen science website where keen-eyed rodent reporters can notify CSIRO about mouse sightings. The website is optimised for mobile phones, and Peter and his team hope to have an app out soon.
“Numbers are everything when you’re trying to predict a plague,” Peter says. “Traditionally we’ve used traps and chew cards [thin pieces of cardboard soaked in vegetable oil], but they have disadvantages, not least the fact that we’re not physically able to put them everywhere. MouseAlert allows us to capture data over a much wider area and potentially spot a plague well before it becomes a problem.”
Equally important as sightings, Peter says, are reports of where mice haven’t been.
“The jump from zero sightings to one or two can be an important indicator that mouse numbers are increasing,” he says. “By participating in citizen science, the public can help us identify these trigger points.”
So how are things looking this year? A little ominous, actually. Unusually high numbers of mice were seen in western Victoria in September. Depending on how much rain we get, they could build up to plague proportions by March or April next year. That’s why Peter wants mouse watchers to keep their eyes peeled:
“If it looks like there’s going to be a plague, we want to be able to give farmers plenty of time before sowing to prepare – or else put their minds at ease if it looks like there isn’t.”
So if you do see a mouse this Christmas Eve – stirring or not – get over to MouseAlert and report it. The pantry you’re saving could be your own!
The sun’s out and the champagne’s been smashed(http://ow.ly/FLqwL)… It’s the RV Investigator’s Welcome to Port day! There’s a shipload of activity taking place in Hobart for this event today, but let’s step back for a second and take a look at just why the Investigator is worth all this fuss. Dive on in and explore below!

The day has finally arrived: our new 94 metre, A$120 million research vessel (RV) Investigator will be commissioned in Hobart today.
This marks Investigator’s transition from being a CSIRO ship building and commissioning project to being Australia’s new Marine National Facility ship, ready to embark on its maiden voyage in March 2015.
You may have noticed we’ve been making quite a bit of fuss about the Investigator recently. Here’s three* good reasons why.
First of all, she’s good news for Tasmania. Between them, Investigator and the Marine National Facility pump somewhere between $7 million and $11 million a year into the local economy. In the last ten years Hobart has become a marine and Antarctic science hub. CSIRO’s Oceans and Atmosphere Flagship and the University of Tasmania’s $45 million Institute for Marine and Antarctic Studies (IMAS) headquarters are located there, along with a large…

On Sunday 7th December 2014, the New Horizons spacecraft, 5 billion kilometres away from the warmth of Earth, had little time to sleep in. It was ‘wake up’ day. The final awakening from hibernation for the next 2 years until well after its encounter with rapidly approaching dwarf planet, Pluto, set for the 14th July 2015.
Waiting back on Earth to hear the spacecraft’s morning ‘alarm’ go off was the giant 70 metre antenna dish at the CSIRO-managed, Canberra Deep Space Communication Complex – Deep Space Station 43 (DSS43).
