Join us on an incredible Wildlife photography adventure through the wilds of Oregon, as we search for and capture stunning images of three iconic raptors: the Great Grey Owl, the Bald Eagle, and the Osprey. What was amazing is that we did not see another photographer whilst photographing these magnificent raptors! From dense forests to riverbanks and high mountain meadows, Oregon is a paradise for birdwatchers and wildlife photographers alike. In this video, we take you behind the scenes of our journey—tracking elusive owls, watching bald eagles, and photographing ospreys.
It makes us extremely proud to be living in this part of America!
We live on 13 acres. Even the land near to the house is difficult to keep tidy so when Jean and I saw this TED Talk given by Rebecca McMacin we were overjoyed. For having a tidy garden does much greater harm to wildlife than keeping it wild.
Before I get to the TED video, I just want to show you some photos I took last Saturday.

Now to the TED Talk
Here is the description of the talk.
Many gardeners work hard to maintain clean, tidy environments … which is the exact opposite of what wildlife wants, says ecological horticulturist Rebecca McMackin. She shows the beauty of letting your garden run wild, surveying the success she’s had increasing biodiversity even in the middle of New York City — and offers tips for cultivating a garden that can be home to birds, bees, butterflies and more.
Here is Rebecca’s background.
Rebecca McMackin is an ecologically obsessed horticulturist who helps people create and care for beautiful gardens that provide habitat for birds, butterflies and soil microorganisms.
Why you should listen
Rebecca McMackin spent a decade as director of horticulture at Brooklyn Bridge Park, where she employed organic principles to manage 85 acres of diverse parkland. During her time overseeing the park’s ecology, stick bugs, rare mantids, threatened bees and lady bugs all returned to the park. The park’s urban biodiversity and successful use of ethical management strategies influenced thousands of people and other urban parks to adopt similar approaches.
In addition to her work designing public gardens, McMackin writes, lectures and teaches on ecological landscape management and pollination ecology. She recently installed an 8,000-square-foot native wildflower garden for the entrance to the Brooklyn Museum. She was a Loeb Fellow at the Harvard Graduate School of Design, while her work has been published by and featured in The New York Times, the Landscape Institute and on NPR and PBS.

As many of you know I was born exactly six months before VE Day on May 8th, 1945.
We soon moved from Acton to 16 Toley Avenue, in Preston Road, Wembley. A short distance down Toley Ave was Ledway Drive that led up to Barn Hill Pond.
A review of Barn Hill Pond by a dog walker, Tara Furlong, in 2020.
It’s a pond on top of a hill, which gets smaller depending on how hot and dry the summer is. It has been known to have sightings of its own grey heron, mallards on occasion, etc. Fish may lurk in its depths, and frogspawn in the spring. There are views of Wembley, and across to central London from the trig point nearby, and aspirations to open up the view to Harrow-on-the-Hill. Take a little wander and you may spy St Paul’s Cathedral. A small number of benches are available, and the bins overflow in fine weather. There’s nothing but green space and houses nearby. It’s accessible via a fairly short, steep uphill walk on uneven ground from the unserviced car park, which can get very busy; or from Wembley Park. Photos on a typical British day – i.e. a bit cloudy and soggy.
As a young boy I well remember looking out from Barn Hill and seeing the devastation of the property from the Nazi bombers.
There are twenty programmes on Radio 4 that are about this postwar period in Britain. I have listened to the first three and have found them deeply interesting. Anyone interested in British history is recommended to listen to them. That is the link.
To my mind, nothing beats the sights of the World’s oceans.
In the past, I spent four years living on a yacht, a Tradewind 33, out in Cyprus. During that time I cruised to Turkey, to Greece, to Algiers, and loved it.
Here’s an extract from World Oceans day website.
Why Earth’s oceans are so important
Earth’s oceans are critical to human survival. Indeed, more than half the oxygen in our atmosphere is generated via photosynthesis by phytoplankton and seaweed in oceans. In addition, millions of people depend on fish and other marine animals for food. Research on some marine organisms has led to the development of new medications. Moreover, ocean currents, known as global conveyor belts, help regulate Earth’s climate.

George Monbiot published an article in The Guardian recently that was as hard-hitting as I have ever read from him.
I found it very powerful even though I have not been living in England since 2008. Mr Monbiot has previously given me permission to republish his articles and here it is.

Four-Year Plan
Posted on 3rd June 2025
Keir Starmer has accidentally given us four years in which to build a new political system. We should seize the chance.
By George Monbiot, published in the Guardian 27th May 2025
This feels terminal. The breaches of trust have been so frequent, so vast and so decisive that the voters Labour has already lost are unlikely to return. In one forum after another, I hear the same sentiments: “I voted for change, not the same or worse.” “I’ve voted Labour all my life, but that’s it for me.” “I feel I’ve been had.”
It’s not dissatisfaction. It’s not disillusionment. It’s revulsion: visceral fury, anger on a level I’ve seldom seen before, even towards Tory cruelties. Why? Because these are Tory cruelties, delivered by a party that claimed to be the only alternative, in our first-past-the-post electoral system.
Like many people, I was wary of Keir Starmer. I had limited expectations, but I willed Labour to succeed. So I’ve watched aghast as he and his inner circle have squandered one of the greatest opportunities the party has ever been granted. They seem to despise people who voted for them, while courting and flattering those who didn’t and won’t.
The results? Last week, the polling company Thinks Insight & Strategy found that 52% of those who voted Labour in the 2024 general election are considering switching to the Liberal Democrats or the Greens. That’s more than twice as many as might migrate to Reform UK. The research group Persuasion UK estimates that Labour could lose 250 seatsas a result of this flight to more progressive parties (again, more than twice as many as it could lose through voters shifting to Reform). Figures compiled by the progressive thinktank Compass show that Labour would lose its majority on just a 6% swing. Already, while it won a massive majority on a measly 34% vote at the election, it now polls at just 22%.
What explains this idiocy? Labour has succumbed, quickly and hard, to the defining sickness of our undemocratic political system: the sofa cabinet system of close advisers. Opaque and unaccountable government favours opaque and unaccountable power. Ever receptive to the demands of rentiers, oligarchs, non-doms and corporations, Labour’s oh-so-clever strategists are moronically giftwrapping the country for Nigel Farage.
Governments don’t start conservative and turn radical. The cruelty will set like concrete. The likely result is annihilation in 2029. On this trajectory, it might not be surprising if Labour were left with seats in only double figures.
Perhaps it’s a blessing that Starmer has shown his hand so soon, as we now have four years in which to prepare. I’m not a party person: for me, it’s a question of what works. And now we can clearly see the shape of it.
The Compass analysis, published in December, reveals extreme electoral volatility. This is caused by a combination of public fury towards austerity, exclusion, rip-off rents and startlingly low rates of wellbeing, and the “democratic mayhem” resulting from a first-past-the-post system in which five parties are now polling at 10% or more. Small vote shifts in this situation can cause wild fluctuations in the allocation of seats.
The report points out that the UK is an overwhelmingly progressive nation: in all but one election since 1979 most voters have supported left or centre-left parties. Of 15 nations surveyed, the UK has the extraordinary distinction of being both the furthest to the left and the most consistent elector of rightwing governments. Why? Because of our first-past-the-post system, which is grossly unfair not by accident but by design. Labour refuses to change it, as it wants to rule alone. The result is that most of the time it doesn’t rule at all.
The thinktank was hoping to mobilise the progressive majority around a revitalised Labour party, but that moment has passed. What the figures show, however, is massive potential for more radical change. A YouGov survey reveals that almost twice as many people want proportional representation in this country as those who wish to preserve the current system. So let’s build a government of parties that will introduce it.
Here’s the strategy. Join the Lib Dems, Greens, SNP or Plaid Cymru. As their numbers rise, other voters will see the tide turning. Encourage troubled Labour MPs to defect. Most importantly, begin the process in each constituency of bringing alienated voters together around a single candidate. This is what we did before the last election in South Devon, where polls had shown the anti-Tory vote evenly split between Labour and the Lib Dems. Through the People’s Primary designed by locals, the constituency decided to back the Lib Dems. The proof of the method can be seen less in the spectacular routing of the Conservatives (as similar upsets occurred elsewhere) than in the collapse in Labour’s numbers, which fell from 17% in 2019, and 26% in a poll before the primary began, to 6% in the 2024 election. The voters took back control, with startling results.
Whether you fully support any of these parties is beside the point. This coalition would break for ever the lesser-of-two-evils choice that Starmer has so cruelly abused, and which has for so long poisoned politics in this country. Game the system once and we’ll never have to game it again.
No longer will we be held hostage, no longer represented by people who hate us. It will be a tragedy if, as seems likely, Keir Starmer has destroyed the Labour party as a major political force. But it will be a blessing if he has also destroyed the two-party system.
Proportional representation is explained in detail here. There is also an explanation on WikiPedia here. From which I quote a small section:
Proportional representation (PR) refers to any electoral system under which subgroups of an electorate are reflected proportionately in the elected body. The concept applies mainly to political divisions (political parties) among voters. The aim of such systems is that all votes cast contribute to the result so that each representative in an assembly is mandated by a roughly equal number of voters, and therefore all votes have equal weight. Under other election systems, a bare plurality or a scant majority in a district are all that are used to elect a member or group of members. PR systems provide balanced representation to different factions, usually defined by parties, reflecting how votes were cast. Where only a choice of parties is allowed, the seats are allocated to parties in proportion to the vote tally or vote share each party receives.
That is a timely and powerful article from George Monbiot.
When my son, Alex, and Lisa, were with us in the second half of last month, they spoke of the tremendous joy they experienced in visiting Yellowstone before they came to us.
A shard of smooth bone etched with irregular marks dating back 20,000 years puzzled archaeologists until they noticed something unique – the etchings, lines like tally marks, may have represented prime numbers. Similarly, a clay tablet from 1800 B.C.E. inscribed with Babylonian numbers describes a number system built on prime numbers.
As the Ishango bone, the Plimpton 322 tablet and other artifacts throughout history display, prime numbers have fascinated and captivated people throughout history. Today, prime numbers and their properties are studied in number theory, a branch of mathematics and active area of research today.
Informally, a positive counting number larger than one is prime if that number of dots can be arranged only into a rectangular array with one column or one row. For example, 11 is a prime number since 11 dots form only rectangular arrays of sizes 1 by 11 and 11 by 1. Conversely, 12 is not prime since you can use 12 dots to make an array of 3 by 4 dots, with multiple rows and multiple columns. Math textbooks define a prime number as a whole number greater than one whose only positive divisors are only 1 and itself.
Math historian Peter S. Rudman suggests that Greek mathematicians were likely the first to understand the concept of prime numbers, around 500 B.C.E.
Around 300 B.C.E., the Greek mathematician and logician Euler proved that there are infinitely many prime numbers. Euler began by assuming that there is a finite number of primes. Then he came up with a prime that was not on the original list to create a contradiction. Since a fundamental principle of mathematics is being logically consistent with no contradictions, Euler then concluded that his original assumption must be false. So, there are infinitely many primes.
The argument established the existence of infinitely many primes, however it was not particularly constructive. Euler had no efficient method to list all the primes in an ascending list.
Prime numbers, when expressed as that number of dots, can be arranged only in a single row or column, rather than a square or rectangle. David Eppstein/Wikimedia Commons
In the middle ages, Arab mathematicians advanced the Greeks’ theory of prime numbers, referred to as hasam numbers during this time. The Persian mathematician Kamal al-Din al-Farisi formulated the fundamental theorem of arithmetic, which states that any positive integer larger than one can be expressed uniquely as a product of primes.
From this view, prime numbers are the basic building blocks for constructing any positive whole number using multiplication – akin to atoms combining to make molecules in chemistry.
Today, primes in this form are called Mersenne primes after the French monk Marin Mersenne. Many of the largest known primes follow this format.
Several early mathematicians believed that a number of the form (2p – 1) is prime whenever p is prime. But in 1536, mathematician Hudalricus Regius noticed that 11 is prime but not (211 – 1), which equals 2047. The number 2047 can be expressed as 11 times 89, disproving the conjecture.
While not always true, number theorists realized that the (2p – 1) shortcut often produces primes and gives a systematic way to search for large primes.
The search for large primes
The number (2p – 1) is much larger relative to the value of p and provides opportunities to identify large primes.
When the number (2p – 1) becomes sufficiently large, it is much harder to check whether (2p – 1) is prime – that is, if (2p – 1) dots can be arranged only into a rectangular array with one column or one row.
Fortunately, Édouard Lucas developed a prime number test in 1878, later proved by Derrick Henry Lehmer in 1930. Their work resulted in an efficient algorithm for evaluating potential Mersenne primes. Using this algorithm with hand computations on paper, Lucas showed in 1876 that the 39-digit number (2127 – 1) equals 170,141,183,460,469,231,731,687,303,715,884,105,727, and that value is prime.
Also known as M127, this number remains the largest prime verified by hand computations. It held the record for largest known prime for 75 years.
Researchers began using computers in the 1950s, and the pace of discovering new large primes increased. In 1952, Raphael M. Robinson identified five new Mersenne primes using a Standard Western Automatic Computer to carry out the Lucas-Lehmer prime number tests.
As computers improved, the list of Mersenne primes grew, especially with the Cray supercomputer’s arrival in 1964. Although there are infinitely many primes, researchers are unsure how many fit the type (2p – 1) and are Mersenne primes.
By the early 1980s, researchers had accumulated enough data to confidently believe that infinitely many Mersenne primes exist. They could even guess how often these prime numbers appear, on average. Mathematicians have not found proof so far, but new data continues to support these guesses.
George Woltman, a computer scientist, founded the Great Internet Mersenne Prime Search, or GIMPS, in 1996. Through this collaborative program, anyone can download freely available software from the GIMPS website to search for Mersenne prime numbers on their personal computers. The website contains specific instructions on how to participate.
GIMPS has now identified 18 Mersenne primes, primarily on personal computers using Intel chips. The program averages a new discovery about every one to two years.
The largest known prime
Luke Durant, a retired programmer, discovered the current record for the largest known prime, (2136,279,841 – 1), in October 2024.
Referred to as M136279841, this 41,024,320-digit number was the 52nd Mersenne prime identified and was found by running GIMPS on a publicly available cloud-based computing network.
This network used Nvidia chips and ran across 17 countries and 24 data centers. These advanced chips provide faster computing by handling thousands of calculations simultaneously. The result is shorter run times for algorithms such as prime number testing.

The Electronic Frontier Foundation is a civil liberty group that offers cash prizes for identifying large primes. It awarded prizes in 2000 and 2009 for the first verified 1 million-digit and 10 million-digit prime numbers.
Large prime number enthusiasts’ next two challenges are to identify the first 100 million-digit and 1 billion-digit primes. EFF prizes of US$150,000 and $250,000, respectively, await the first successful individual or group.
Eight of the 10 largest known prime numbers are Mersenne primes, so GIMPS and cloud computing are poised to play a prominent role in the search for record-breaking large prime numbers.
Large prime numbers have a vital role in many encryption methods in cybersecurity, so every internet user stands to benefit from the search for large prime numbers. These searches help keep digital communications and sensitive information safe.
I find it unbelievable that there are prizes for the first 100 million-digit prime number and also the first 1 billion-digit prime number. It is so far away from my understanding of these numbers that all I can say is: I find it unbelievable!
When my son and his partner, Lisa, were with us, just over a week ago, Alex suggested that he and I explored Sexton Mountain; some three miles to the North-East, as the crow flies. Normally the final stretch has to be walked because of a locked gate across the trail. However, that day the last 8/10ths of a mile were driven. It was a beautiful place with that summit 3,833 feet above sea-level (U.S. Geological Survey).

Going Green with Fur and Grit: How to Launch an Eco-Friendly Pet Care Business That Actually Work
You’ve been sitting on the idea for a while now. Maybe it started with that pile of single-use plastic baggies after your dog’s walk, or the ingredient list on your cat’s kibble that read more like a chemistry project than actual food. Maybe you just got tired of feeling like you had to choose between loving your pet and loving the planet. Whatever the reason, you’re here now, staring down the reality of launching a business that’s not only built for animals—but built for good. You want to make something that matters. And you can. But you need to know exactly what you’re walking into.
Anchor Yourself in a Real Way
You can’t build this kind of business on good vibes and a cool logo. Before anything else—before the business plan, the branding, or the Instagram account—you’ve got to know exactly why you’re doing this. If your reason isn’t rooted in something deeply personal, something that makes your chest tighten when you think about it, you’ll burn out fast. Maybe it’s watching your senior dog react to over-processed treats, or maybe it’s the garbage island growing in the ocean—whatever it is, let that be your compass.
Streamline the Chaos with the Right Tools
When you’re building a mission-driven business from scratch, the backend can get messy fast. That’s where using an all-in-one business platform becomes a game-changer—it keeps your focus on your values instead of your paperwork. Whether you’re forming an LLC, managing compliance, creating a website, or handling finances, this type of platform can provide comprehensive services and expert support to ensure business success. Platforms like ZenBusiness are built for entrepreneurs like you, giving you the structure to stay organized while you pour your energy into the work that really matters.
Get Ruthlessly Local with Sourcing
If you’re serious about sustainability, you’ve got to look hard at where your products come from. Local sourcing doesn’t just reduce your carbon footprint—it tells your community that you care about it. Reach out to nearby farms, independent makers, and ethical manufacturers who align with your mission. Not only will this lower your shipping emissions, it’ll also create real relationships with partners who have skin in the game—and people can feel that authenticity the moment they walk through your door.
Know That Packaging Will Be a Battle
You’re going to lose sleep over packaging. You’ll try compostable options that fall apart in humid weather. You’ll learn that “recyclable” doesn’t mean the same thing in every city. And somewhere along the way, you’ll realize that the most sustainable solution might be the least convenient one. This is the part where you have to experiment, ask questions, and stay transparent with your customers. No one expects perfection—but they’ll appreciate your effort to figure it out.
Make the Community Your Co-Founders
You’re not building this business for yourself. You’re building it for every person who loves their animal and wants to do better by the planet. So bring them in early. Host small events, set up “ask me anything” nights, partner with local shelters, and turn your customer base into a real community. These people won’t just buy your products—they’ll give you feedback, advocate for your brand, and make you feel less alone when the grind gets real.
Ditch the Guilt, Offer Solutions
You’re not here to shame anyone. The pet parent buying big-box kibble isn’t your enemy—they’re someone who probably hasn’t been offered a better option yet. So don’t lecture. Instead, educate through action. Make eco-friendly choices feel fun, feel doable, and feel worth it. When you center your messaging on empowerment instead of guilt, people are way more likely to stick around—and tell their friends.
Teach Through Curiosity, Not Preaching
People want to learn, but they don’t want to be condescended to. Your job is to become the kind of brand that shares knowledge without turning it into a TED Talk. Drop bite-sized facts on your packaging, start conversations in-store, and use your social platforms to casually open people’s eyes. Think of it like planting seeds—not every customer will bloom overnight, but the ones who do will remember how you made them feel when they were just getting started.
Hire with Heart, Not Just Skill
You can train someone to trim nails or restock shelves, but you can’t teach them to care. The team you build needs to believe in the mission as much as you do. They’re the ones explaining the difference between corn-based and petroleum-based bags to a frazzled pet parent who’s late for pickup. If your staff is just collecting paychecks, your message won’t land. But if they’re aligned with your values? That’s when your business becomes a movement.
Don’t Let Perfect Be the Point
You will mess up. You’ll stock a “sustainable” product that turns out to be greenwashed. You’ll order packaging that gets held up in customs. You’ll have days where you wonder if any of this actually matters. That’s normal. Progress in this space is messy, nonlinear, and full of trade-offs. The key is to keep going, stay honest, and let your customers come along for the ride. They don’t need you to be flawless—they just need to believe you’re trying.
Starting an eco-conscious pet care business means doing things the hard way on purpose. It means waking up early to answer emails from suppliers and staying up late comparing compostable labels. It means showing up for your customers, your team, your animals—and the planet. But if your heart’s in the right place and your feet stay on the ground, you’ll build something that matters. And really, that’s the kind of work worth doing.

As a very ex-entrepreneur, I can tell you that there is much in Penny’s article that applies to starting any business.
And as an ex-salesman, everything starts with the customer. The persons who are attracted to what you are selling. It is hard work but pleasing work. Before I started Dataview I worked for IBM UK in their office products division, as a salesman. I loved the job!
NASA hasn’t landed humans on Mars yet. But thanks to robotic missions, scientists now know more about the planet’s surface than they did when the movie, The Martian, was released.
Our human knowledge is constantly growing. In many, many directions. Here is a fascinating (well it is to me!) article from The Conversation.

A decade after the release of ‘The Martian’ and a decade out from the world it envisions, a planetary scientist checks in on real-life Mars exploration
‘The Martian’ protagonist Mark Watney contemplates his ordeal. 20th Century Fox
Andy Weir’s bestselling story “The Martian” predicts that by 2035 NASA will have landed humans on Mars three times, perfected return-to-Earth flight systems and collaborated with the China National Space Administration. We are now 10 years past the Hollywood adaptation’s 2015 release and 10 years shy of its fictional timeline. At this midpoint, Mars exploration looks a bit different than how it was portrayed in “The Martian,” with both more discoveries and more controversy.
Although concepts for crewed missions to Mars have gained popularity, NASA’s actual plans for landing humans on Mars remain fragile. Notably, over the last 10 years, it has been robotic, rather than crewed, missions that have propelled discovery and the human imagination forward.
NASA’s 2023 Moon to Mars Strategy and Objectives Development document lays out the steps the agency was shooting for at the time, to go first to the Moon, and from there to Mars. NASA
Robotic discoveries
Since 2015, satellites and rovers have reshaped scientists’ understanding of Mars. They have revealed countless insights into how its climate has changed over time.
As Earth’s neighbor, climate shifts on Mars also reflect solar system processes affecting Earth at a time when life was first taking hold. Thus, Mars has become a focal point for investigating the age old questions of “where do we come from?” and “are we alone?”
The Opportunity, Curiosity and Perseverance rovers have driven dozens of miles studying layered rock formations that serve as a record of Mars’ past. By studying sedimentary layers – rock formations stacked like layers of a cake – planetary geologists have pieced together a vivid tale of environmental change that dwarfs what Earth is currently experiencing.
Mars was once a world of erupting volcanoes, glaciers, lakes and flowing rivers – an environment not unlike early Earth. Then its core cooled, its magnetic field faltered and its atmosphere drifted away. The planet’s exposed surface has retained signs of those processes ever since in the form of landscape patterns, sequences of layered sediment and mineral mixtures.

Arabia Terra
One focus of scientific investigation over the last 10 years is particularly relevant to the setting of “The Martian” but fails to receive mention in the story. To reach his best chance of survival, protagonist Mark Watney, played by Matt Damon, must cross a vast, dusty and crater-pocked region of Mars known as Arabia Terra.
In 2022 and 2023, I, along with colleagues at Northern Arizona University and Johns Hopkins University, published detailed analyses of the layered materials there using imagery from the Mars Reconnaissance Orbiter and Mars Odyssey satellites.
By using infrared imagery and measuring the dimensions of surface features, we linked multiple layered deposits to the same episodes of formation and learned more about the widespread crumbling nature of the terrain seen there today. Because water tends to cement rock tightly together, that loose material indicates that around 3.5 billion years ago, that area had a drying climate.
To make the discussions about this area easier, we even worked with the International Astronomical Union to name a few previously unnamed craters that were mentioned in the story. For example, one that Watney would have driven right by is now named Kozova Crater, after a town in Ukraine.
More to explore
Despite rapid advances in Mars science, many unknowns remain. Scientists still aren’t sure of the precise ages, atmospheric conditions and possible signatures of life associated with each of the different rock types observed on the surface.
For instance, the Perseverance rover recently drilled into and analyzed a unique set of rocks hosting organic – that is, carbon-based – compounds. Organic compounds serve as the building blocks of life, but more detailed analysis is required to determine whether these specific rocks once hosted microbial life.
The in-development Mars Sample Return mission aims to address these basic outstanding questions by delivering the first-ever unaltered fragments of another world to Earth. The Perseverance rover is already caching rock and soil samples, including ones hosting organic compounds, in sealed tubes. A future lander will then need to pick up and launch the caches back to Earth.
Sampling Mars rocks could tell scientists more about the red planet’s past, and whether it could have hosted life.
Once home, researchers can examine these materials with instruments orders of magnitude more sensitive than anything that could be flown on a spacecraft. Scientists stand to learn far more about the habitability, geologic history and presence of any signs of life on Mars through the sample return campaign than by sending humans to the surface.
This perspective is why NASA, the European Space Agency and others have invested some US$30 billion in robotic Mars exploration since the 1960s. The payoff has been staggering: That work has triggered rapid technological advances in robotics, telecommunications and materials science. For example, Mars mission technology has led to better sutures for heart surgery and cars that can drive themselves.

Calling the red planet home?
Colonizing Mars has a seductive appeal. It’s hard not to cheer for the indomitable human spirit while watching Watney battle dust storms, oxygen shortages and food scarcity over 140 million miles from rescue.
Much of the momentum toward colonizing Mars is now tied to SpaceX and its CEO Elon Musk, whose stated mission to make humanity a “multi-planetary species” has become a sort of rallying cry. But while Mars colonization is romantic on paper, it is extremely difficult to actually carry out, and many critics have questioned the viability of a Mars habitation as a refuge far from Earth.
Now, with NASA potentially facing a nearly 50% reduction to its science budget, the U.S. risks dissolving its planetary science and robotic operations portfolio altogether, including sample return.
Nonetheless, President Donald Trump and Musk have pushed for human space exploration to somehow continue to progress, despite those proposed cuts – effectively sidelining the robotic, science-driven programs that have underpinned all of Mars exploration to date.
Yet, it is these programs that have yielded humanity’s richest insights into the red planet and given both scientists and storytellers like Andy Weir the foundation to imagine what it must be like to stand on Mars’ surface at all.
