From seeing the first ever up-close images of Pluto, to finding water on Mars, to Stephen Hawking teaming up with a Russian billionaire in the search for aliens, 2015 has been a huge year for space exploration. So as we celebrate World Space Week, it seems quite fitting that our minds cast back to another big year for space. In fact, the biggest of them all: 1969, the year Neil Armstrong and Buzz Aldrin became the first humans to set foot on the moon.
But before you settle into your lounge, office chair or ergonomic workspace for our tale of space history, we have got some big news. To celebrate Buzz Aldrin’s upcoming visit to Australia next month, we’ve managed to get our hands on some front row tickets to see the famous astronaut in person. He will be captivating audiences in Sydney and Melbourne with a journey through space and time, from the historic walk on the moon to his vision for a future manned mission to Mars.
We’ve got more details on how you can win at the bottom, but right now we’d like to take a trip down our own memory lane, as we recall our role in one of humanity’s most significant achievements.
At 12.56 pm on 21 July 1969 Australian Eastern Standard Time (AEST), mankind took its ‘one giant leap’ and 600 million people watched as Neil Armstrong walked on the Moon.
Our Parkes radio telescope, along with NASA’s antenna at Honeysuckle Creek near Canberra, played a key role in televising the first moon walk.
The ‘Dish’ famously supported receiving the television signals on that momentous day. Although many people think the Parkes telescope was the only station receiving the signal, it was the 26-metre antenna at NASA’s Honeysuckle Creek space tracking station near Canberra that was the prime station assigned with receiving the initial TV pictures from the Moon and Neil Armstrong’s first steps on the lunar surface. (The Tidbinbillla deep space tracking station, today known as the Canberra Deep Space Communication Complex, provided support to the command module in lunar orbit.)
Eight and a half minutes after those first historic images were broadcast around the world, the television signal being received by the larger 64-metre Parkes radio telescope was then selected by NASA to provide the images for the following two hours and 12 minutes of live broadcast as the Apollo 11 astronauts explored the Moon surface.
While the Parkes telescope successfully received the signals, the occasion didn’t go without a hitch. The lunar module had landed at 6.17am AEST. Astronauts Neil Armstrong and Buzz Aldrin were supposed to rest before the Moonwalk, but Neil Armstrong was keen to get going. The astronauts were slow getting into their suits and when they got outside the Moon was rising over Parkes.
The telescope was fully tipped over, waiting for the Moon to rise, when a series of strong wind gusts – 110 km per hour – hit. They made the control room shudder, and slammed the telescope back against its zenith axis gears. Fortunately the wind slowed, and Buzz Aldrin activated the TV camera just as the Moon came into the telescope’s field-of-view. At this time, Honeysuckle Creek was taking the main signal. Eight minutes later the Moon was in the Parkes main detector’s field-of-view and NASA switched to Parkes. The weather was still bad, and the telescope operated well beyond its safety limits.
The signals received by Parkes were sent to Sydney. From there the TV signal was split. One signal went to the Australian Broadcasting Commission, the other to Houston for the international telecast. The international signal had to travel halfway around the world from Sydney to Houston, adding a delay. So Australian audiences saw Neil Armstrong’s historic first step 0.3 seconds before the rest of the world.
To celebrate Buzz’s visit, we’re giving away 3 tickets for both the Sydney and Melbourne events. Entering is simple enough: we want you to take a moon selfie using the hashtag #MoonBuzz. But instead of taking a selfie with the moon, we want you to take a selfie as the moon. All you need to do is get your hands on a camera and a toilet roll (bear with us here, we’re not raving lunar-tics) and follow these steps:

Amid growing demand for seafood, gas and other resources drawn from the world’s oceans, and growing stresses from climate change, we examine some of the challenges and solutions for developing “the blue economy” in smarter, more sustainable ways.
Diving the warm, crystal clear waters of Indonesia’s Raja Ampat Marine Park is an experience for the lucky few. Its coral reefs attract a huge variety of marine life, including turtles, manta rays and countless species of tropical fish – including the now iconic clownfish.
If you’ve gone diving there recently, or are planning a holiday, you may have noticed that the marine park fees have gone up sharply in past 12 months – as they have in many other parts of Indonesia, Malaysia and Thailand.
But you might actually be happy to discover why.
The cost of caring for coral reefs
The dive industry has long been criticised as contributing to declines in coral reef health around the world. Coral reefs globally are under increasing pressure from the cumulative impacts of fishing, shipping, and coastal development, as well as longer-term impacts due to climate change. And unless it’s managed, increased diving and snorkelling tourism can become just another environmental strain.
That’s not in anyone’s interests. Failure to adequately manage activities within reef areas is likely to lead to their degradation, which will make them less attractive to divers and other tourists in the long-term.
But taking better care of our reefs comes at a cost. It requires monitoring and surveillance, as well as ensuring users (such as divers) and beneficiaries (such as local businesses) of the reefs are aware of their impacts and understand how to avoid them.
Across Indonesia, Malaysia and Thailand, dive tourism directly dependent on the health of coral reefs brings in around US$1.5 billion a year to local communities. Most of this is in remote areas, where alternative sources of income are limited.
Those three countries have set up a number of marine parks to protect their reefs. And about 70% of those parks have long had dive fees in place.
But the fees have typically been very low, while government contributions were also relatively constrained – which is why a 2006 study found that only about one in seven marine reserves in south east Asia had adequate financial resources.
That’s where learning from the Australian experience, together with modelling work from an international team of researchers, has helped provide a practical solution.
How tourists help pay to preserve the Great Barrier Reef
The Great Barrier Reef Marine Park is one of Australia’s great tourism international drawcards – for divers in particular – injecting an estimated AUS$5 billion into the economy and generating around 64,000 full-time equivalent jobs.
But right from the early days of establishing the Great Barrier Reef Marine Park, Australia had to grapple with how to pay for crucial conservation work.
That’s why divers and other visitors to the Great Barrier Reef Marine Park each pay an environmental management charge of AU$6 a day. That contributes around 20% of the AU$40 million annual management costs.
Modelling to test what impact this charge has on visitor numbers suggests that it is very small, and the gains in terms of financial resources for management far exceed any potential losses to local businesses – which, after all, also depend on the reef for their continued survival.
Testing a model solution
But until a few years ago, the idea of charging higher fees was opposed by many tourism and related businesses in south east Asian diving communities, concerned that it might cause tourist numbers and earnings fall.
In 2013, a group of international researchers supported by the Asia-Pacific Network for Global Change Research worked with managers, resort owners and dive operators in Indonesia, Malaysia and Thailand to develop options for improved reef management in the region.
This included modelling what might happen if you increased dive fees to pay for reef conservation. That study predicted that even if the conservation fees were more than doubled, it was unlikely to deter many divers, who care about the places they go diving in.
It also predicted that the revenue raised for reef protection would far exceed the loss in tourism expenditure in local communities, and help ensure that the communities as well as the reefs would survive into the future.
What higher diving fees are funding
Since then, as any keen divers reading this might already have seen, user fees in many of their marine parks have been introduced or increased. For example, at the Raja Ampat Marine Park in Indonesia, fees for foreign visitors have doubled in 2015 to 1,000,000 Indonesian Rupiah (about AU$100) for an annual permit.
More modest fee increases (and fee levels) have also been seen in most Thai and Malaysian marine parks this year, with most now charging international visitors between AU$10 and AU$20 a day for access.
So what are you paying for? Among other things, divers are helping by paying more for rangers’ wages and for patrols to keep out illegal fishing, mining and poachers, as well as conservation and reef rehabilitation projects in the parks.
But when you consider how much it costs to go on a diving holiday, being asked to pay the equivalent of a light meal is not too much to ask. Indeed, from the modelling study, most visitors gain substantially much more than this in terms of benefits from diving on these coral reefs, and could potentially contribute greater amounts to protect them for future generations.
By digging a little deeper, divers can do more than just go on holiday: they can contribute to longer-term conservation of some of the most extraordinary places on Earth.

You don’t need a crystal ball to know Australia’s rural industries will face significant change at global, national and local levels over the coming decades. This will create opportunities and challenges for small and large farms, and will affect rural lifestyles, agricultural landscapes and Australia’s society and economy.
In a new report, we describe this future through a series of interlinked “megatrends” set to hit Australia over the coming 20 years. As we describe below, each prompts some serious questions (or “conversation-starters”, as we have termed them) for Australian farmers. We don’t yet know the answers, but we do know they will be crucial for how the industry fares in the future.
The world will get hungrier
We know that the world is going to require more food as populations grow – about 70% more by 2050, according to the United Nations. This will come primarily from increasing yields, along with some expansion of agricultural land.
The target is achievable but should not be taken for granted. There are competing uses of land for biofuels and urbanisation; in some places land is degrading; and we don’t have good predictions yet of the effect of climate change on agriculture. As a significant exporter of food, Australia has a vital role to play in supplying world food markets and buffering supply shocks.
We are well positioned — both in terms of geography and comparative advantage — to supply overseas markets. And while Australia can’t hope to feed Asia or the world, with astute R&D investment it can increase production and exports. How well we step up to that challenge depends largely on our ability to maintain a price competitive position and continue to improve yields. So the key questions are:
Will farms be able to scale up production and performance to meet this challenge?
What is a sensible investment in innovation, and how should it be funded?
The world will get wealthier
Some 1.02 billion people will move out of poverty and into the middle classes in the developing Asia region alone by 2040. Along with wealth comes the ability to diversify food choices – wealthier households will consume more meat, dairy and vegetable oils.
This presents an opportunity for Australian rural industries to identify new food types and connect to new markets. A diversified rural export base is likely to be more resilient to supply-and-demand shocks in markets.
Is Australia better off focusing on commodity markets that have provided solid export earnings, or should it be working hard to respond to the demand for a more diverse range of boutique, luxury and niche food and fibre goods?
Does Australia have the infrastructure and the persistence to get a wider range of desirable agricultural products into Asian markets competitively?
Customers will get pickier
The consumer of the future will be increasingly able and motivated to choose food and fibre products with certain characteristics. This has impacts both within and beyond the farm gate. Information technology will increasingly enable the consumer to access, share and validate information about products along the whole supply chain from farm to fork.
Health is likely to become a particularly prominent driver of food choice and consumption patterns – be that from a desire for food safety or to help prevent chronic disease. Many people’s lives are being cut short by poor diets, and at current trajectories government budgets could become crippled by unsustainable growth in healthcare expenditure.
The issues of environment, provenance and ethics will also play a vital role. The consumer of the future will have greater expectations for these qualities in the food and fibre products they choose to buy. Consumers will be “information-empowered” and rural industries stand to gain or lose market share based on this increase in consumers’ knowledge.
In the face of soaring diet-related health costs, will governments increase control of the components of food and diets?
How does agriculture in Australia build and safeguard its clean, green reputation?
Technologies will transform farm life
Advances in digital technology, genetics and materials science will change the way food and fibre products are created and transported.
Many plant productivity breakthroughs will be from gene technology. Big data systems and digital technologies will bring better risk-management approaches to Australian agriculture; weather and yields will be much more predictable and farmers will have sophisticated tools to assist with decision making.
Knowledge about land use and framing practices will increasingly move into the public domain as remote monitoring, be it from drones or satellites, makes available new data in a highly interconnected world. Business and capital models will change with the introduction of “disruptive” technologies such as peer-to-peer lending.
Will market perceptions hold back Australian agriculture by restricting access to advanced technologies being used by our major competitors?
How will farmers manage a higher level of scrutiny of their operations?
The rollercoaster of risks will get bumpier
Risk is an ever-present characteristic of Australian agriculture. However, the coming decades will see changes in the global climate, environmental systems and the world economy which will create new and potentially deeper risks for farmers.
Australian agriculture has shown a strong capacity to adapt and respond to risks in the past. But as trade globalises and we rely more on imported inputs such as fertiliser and fuel, the risk of supply chain shocks increases.
More international trade and passenger travel brings greater biosecurity risks. Climate change impacts are not well understood, and the need to cut greenhouse gas emissions will set up competing land uses for both biofuels and carbon storage.
Do we understand the likely implications of a global price on carbon of US$50-100 per tonne?
Is the agriculture sector at risk of complacency and underinvestment when it comes to risk management?
Overall, there is a bright future for Australian agriculture, laden with deep and diverse opportunity. The future outlined above will be a challenge for some producers and industries but an opportunity for others. The effectiveness with which Australian agriculture captures these opportunities and avoids the risks will largely come down to innovation.
Through centuries past, repeated innovation has allowed Australian farmers to expand into new land areas, develop water resources and increase crop and pasture yields. As we look to the decades ahead, innovation becomes ever more important. In a world of exponential growth in both technology and global trade, it’s about working smarter, not just harder.
If you’re a parent, how important is it to you that your child have an inquisitive mind? One that is imaginative and curious and seeks out a different path. A mind that has a thirst for challenge.
At work, it’s the colleague you seek when all else has failed. As a manager, it’s the person you hope will walk in the door when you sit on an interview panel.
It’s the kind of thinking you nurture through science, engineering, maths and technology (STEM). And it’s the kind of thinking that leads you to CSIRO.
Today, we’re playing host to over 100 events around Australia to drum up support for these subjects at school.
We’re doing this through our Scientists and Mathematicians in Schools (SMiS) program. SMiS is a national volunteer program bringing real science, maths and ICT into primary and high school classes through partnerships between teachers and STEM professionals.
To kick-start National Science Week, we’ve invited a raft of pollies to join us in a science activity at their local school. We’ll be using this blog to host a live photo gallery of today’s events so check back in when you can.
Follow the conversation using #STEMinschools.

We tend to think about our healthcare sector as a leader in the development and use of advanced medical technology and biotechnology, such as expensive imaging machines or devices that we implant into patients.
But in many aspects of conducting the business of healthcare, our healthcare system is still in a pre-digital era. For example, healthcare may be the last sector where significant amounts of communication are still done via fax and regular post.
This is not to say that significant changes are not happening. Radiology is increasingly using digital technology but the interpretation of these images is still manual. Electronic health and medical records are also being introduced widely but there is little communication between collectors.
The digital revolution in healthcare that is currently slowly unfolding will use data and technology to improve the healthcare of patients. It will also increase safety and quality, and improve efficiency in the healthcare system.
The eyes have it… remotely
One example of how technology can be used to deliver better healthcare is a recent trial by CSIRO and our partners that provided screening for eye diseases among people in remote parts of Western Australia and Queensland.
Using the NBN’s satellite broadband service, we screened more than 1,200 people in their communities for diseases such as diabetic retinopathy. This disease often causes irreversible blindness, and it affects the Indigenous population at nearly four times the rate of the non-Indigenous population.
Local health workers were trained at capturing high-resolution images of a patient’s retina with a low-cost retinal camera. These images were stored then uploaded over the NBN satellite to ophthalmologists in Brisbane and Perth.
The screening program identified 68 patients who were at high risk of going blind, including those with macular edema. In the most case these patients received treatment locally. However, some patients needed transfer to major hospitals for immediate treatment.
Once patients were identified as being at risk of significant eye disease, they were provided with care plans that involved local follow up consultations and regular screening the tele-eye care screening program.
For diabetic patients this included advice on controlling their diabetes, which improves their overall health as well as reducing the risk of blindness.
We have the technology
Overall, the trial showed the effectiveness of providing a “store and forward” tele-ophthalmology service using satellite broadband. These types of services have previously been held back by unreliable broadband services and the lack of digital systems in our health services to interact with them.
Reliable broadband connectivity together with increased use of digital systems by health services means that these methods of health service delivery can now become the normal way healthcare is provided.
But for these tele-enabled models of care to really take off, patient data must be shared between providers. At the moment, different healthcare providers – GPs, specialist doctors and emergency departments at local hospitals – all separately collect information about the same patients.
This means that the services that a patient receives are generally uncoordinated. With the increase in chronic diseases, such as diabetes and eye-disease, coordinated care will lead to better health outcomes.
For providers to share data requires their computer systems to be able to send and receive data, and make sure that the data is added to the correct patient’s electronic record.
This is where the type of algorithms that power search engines such as Google – semantic web and information retrieval technologies – can be tailored for healthcare systems. Shared properly, the data can be used to make sure that patients receive appropriate services.
Sharing this data will also mean that there is a bigger volume of data about a patient with each healthcare provider. This will require computers to do more to analyse the data and alert patients, clinicians and health care providers when there should be follow up action.
More IT jobs needed in healthcare
The increase in the use of digital technologies will not only boost healthcare. This is a sector where there will be a significant boost in the number of IT professionals, including data scientists, needed to work.
Big data analytics will be required to analyse the large volumes of different types of data that are being collected at an increasing rate.
But it is not just about applying these new technologies in healthcare. There is also a need to work with clinicians and health service executives to understand what data is – or could be – collected. This may lead to a new way of providing clinical care, a new health service, or even make existing processes more efficient.
For data analysts and IT professionals working in healthcare, the opportunities to make a difference to patients are almost boundless.
Did you hear the news? We’ve just had a new Chair appointed to head our Board! Ladies and gentlemen, introducing Mr David Thodey. You may have heard the name before – David is no stranger to high profile roles here in Australia. Most recently he was CEO of Telstra – where he has been credited with significantly increasing Telstra’s share price and doubling the value of the company – and before that he was CEO of IBM Australia/New Zealand.
It’s an exciting time for David to be joining us. The next five years are going to be important for us as we become a global collaboration hub, and help boost the country’s innovation performance.
With David’s proven business acumen and experience running large, innovative organisations, our CE Larry Marshall’s passionate support of innovation and Australian entrepreneurs, and more than 5,000 of Australia’s greatest scientific minds dedicated to the cause, rest assured we’ll be giving it a red hot go.
David sat down with us this week to talk about why he took up the role, and how he’ll be both embracing and driving the massive technological change taking place around the world right now.
Using David’s business expertise, we’re looking to build on our already strong business and industry partnerships. If you’re interested in doing business with us, now’s the time.
We’d also like to thank outgoing Chair Simon McKeon for his years of excellent service to our organisation.
Based on current greenhouse gas emissions, the world is on track for 4C warming by 2100 – well beyond the internationally agreed guardrail of 2C. To keep warming below 2C, we need to either reduce our emissions, or take carbon dioxide out of the atmosphere.
Two papers published today investigate our ability to limit global warming and reverse the impacts of climate change. The first, published in Nature Communications, shows that to limit warming below 2C we will have to remove some carbon from the atmosphere, no matter how strongly we reduce emissions.
The second, in Nature Climate Change, shows that even if we can remove enough CO2 to keep warming below 2C, it would not restore the oceans to the state they were in before we began altering the atmosphere.
How we’re tracking
Currently, we’re at 400 parts per million – rising from 280 ppm before the industrial revolution.
To project future climate change the Intergovernmental Panel on Climate Change (IPCC) uses a range of emissions scenarios called Representative Concentration Pathways (RCPs), based on different economic and energy use assumptions.
In the high scenario, RCP8.5, emissions continue to grow from our present rate of 37 billion tonnes of CO2 per year to about 100 billion tonnes of CO2 in 2100, when atmospheric CO2 levels are projected to be 950 ppm. This scenario assumes little mitigation of our carbon emissions.
In the low scenario, RCP2.6, emissions rise slowly till the end of this decade to about 40 billion tonnes CO2 each year and then start to decline. Amongst the IPCC emission scenarios, only the RCP 2.6 appears capable of limiting warming to below 2C. With RCP 2.6 at the end of the century atmospheric concentrations is about 420 ppm, and only 20 ppm above the present value.
Present emissions are tracking close to the highest scenario (RCP8.5). If we want to keep warming below 2C it requires a substantial reduction in the amount of CO2 released into the atmosphere.
What we have to do
We have two options by which to reduce emissions, the first through reducing the use of fossil fuel energy, and the second through Carbon Dioxide Removal (CDR).
CDR refers to technologies that remove CO2, the primary greenhouse gas, from the atmosphere. Examples include Biomass Energy with Carbon Capture and Storage (BECCS), afforestation (planting trees), adding iron to the ocean, and directly capturing CO2 from the air.
For many CDR technologies the boundary between “climate intervention” (or “geoengineering”) and greenhouse gas mitigation is unclear. However, the goal is the same, enhancing the CO2 current taken up and sequestered by the land and ocean.
Can we just remove carbon?
The first study, led by Thomas Gasser, used results from 11 Earth System Models, in conjunction with a simple carbon-cycle models to simulate different emissions reductions scenarios associated with the low emissions pathway, RCP2.6.
They showed that under all emissions reductions scenarios, even slashing emissions to less than 4 billion tonnes CO2 each year, (greater than a 90% cut in current emissions) is insufficient to limit warming to 2C.
This means that some form of CDR will be required to keep warming at less than 2C. The exact level of CDR required depends very much on the emissions reduction achieved, from 2 billion to 10 billion tonnes of CO2 each year in the most optimistic scenario, to between 25-40 billion tonnes CO2 each year in the lowest emission reduction case. This is equivalent to current total global emissions.
The study also suggests that the requirements for CDR may indeed be even higher if unanticipated natural carbon cycle (positive) feedbacks were to occur. We may desire the ability to remove more carbon from the atmosphere to compensate for these.
The other study, led by Sabine Mathesius, explores whether CDR under high CO2 emissions can achieve a similar environmental outcome to a rapid transition to a low carbon energy use (RCP2.6).
It shows that aggressive CDR can only undo the effect of high emissions (RCP8.5) and return the marine environment to either pre-industrial values or the low emission scenario over thousands of years. The ability to undo the damage caused by high emissions reflects timescale of the ocean carbon cycle. While the upper ocean quickly reaches equilibrium with the atmosphere, the deeper ocean takes millennia to restabilise.
Such irreversibility of the system is an important consequence and the study provides valuable information to consider as we tackle rising CO2 levels. Both studies are theoretical but they provide an important perspective on the ability of mankind to engineer the climate system and undo the effects of high CO2 levels in the atmosphere.
No CDR or suite of CDR technologies exists capable of removing the levels of CO2 at the upper range of what maybe required. This means that, while CDR could aid in limiting global temperatures below 2C, in practice this is not even yet possible, and would not be without risks. This continues to be a very active area of research.
While the focus of both studies explore reversing the environmental changes of rising CO2, the climate system is complex and the possibility that mitigation options like CDR could produce unforeseen impacts is high. While reducing carbon emissions is the safest and preferred path for avoiding dangerous climate change and ocean acidification, it is likely that some CDR will be required to achieve this.
