I admit it: I’m a space geek. I avidly followed the space program when I was a kid and watched all of the launches and landings, I joined The Planetary Society when I was a college student and got some great photos of planets taken by exploratory spacecraft of the ’70s that I tacked up on the wall around my desk, and I’ve been hooked on space and planets and the technological advances made in our exploration efforts ever since. That’s why I think what we’re doing now on Mars is pretty darned thrilling.
The photo above is a picture of the latest Mars rover, Perseverance, taken by Ingenuity, the helicopter/drone that has been taking short flights over the surface of Mars. It’s not the greatest photograph from a technical standpoint, of course, but the amazing thing is that it is a picture of human technology taken by another item of human technology on the surface of a distant, alien planet. The picture was snapped on Sunday on Ingenuity‘s third, and longest, flight over old Mars, when Ingenuity was about 16 feet above the Martian landscape and about a football field away from Perseverance.
We keep making significant advances in the space arena, whether it is developing reusable capsules and rockets, sending drones to Mars, or seeing more entrepreneurs entering the space technology and exploration business. It makes me believe that the next few years are going to see some real landmarks established: space tourism, permanent bases on the Moon, and even human landings on Mars. But for now, a blurry, grainy photo of Perseverance is still a pretty cool thing.
The successful launch yesterday marks two milestones. It’s the first launch of human beings into space from the Kennedy Space Center since 2011, when the last space shuttle mission occurred. More significantly, the launch is a huge step forward in America’s entire approach to spaceflight and space exploration and development. The launch vehicle and “Crew Dragon” capsule carrying the astronauts were designed and built by SpaceX, one of the many private companies that are working to make spaceflight a successful commercial venture.
The new approach has several consequences. For one, it is unquestionably cheaper for taxpayers. In addition, the interplay between private companies looking to control costs while delivering the required product and governmental engineers who have long experience with spaceflight issues is producing innovation and new perspectives on how to solve problems. And finally, the successful launch of SpaceX’s Crew Dragon, atop a SpaceX Falcon 9 rocket, demonstrates that commercial spaceflight works. SpaceX is one of many private companies that are making space their mission, and yesterday’s triumph will undoubtedly spur other companies to look to space as a new frontier for investment and commercial activity. If, as many of us hope, spaceflight is to become a routine activity, with expansive space stations and lunar bases and the exploration of Mars as the next steps, the involvement of private investment and private capital will be essential to making that dream a reality.
Yesterday’s launch marks the Era of the Dragon in spaceflight. It’s the first time in history that equipment built by a private company has carried human beings into space. It won’t be the last.
Let’s say we’ve moved some time into the future, when interstellar space travel has become commonplace. You’re on board a Virgin Galactic or SpaceX or Blue Horizons or Heinlein Enterprises flight down to Nimbus, in a solar system in the Orion constellation, when you look down at your destination and . . . it’s a planet that looks like a giant, unblinking eyeball against the dark, star-filled sky.
That would make your cool little space voyage even cooler, wouldn’t it?
Scientists believe that there may be “eyeball planets” out there, just waiting to be visited. They would look like eyeballs because they would be tidally locked with the star they are circling, so one side of the planet always faces the star — just like one side of the Moon always faces the Earth, so that we Earth dwellers never get to see the Dark Side of the Moon. In such circumstances, the “light side” of the planet facing the star and absorbing the brunt of the sun’s radiation, heat, light, and solar wind, is bound to be a lot different than the “dark side” — hotter than the dark side, for sure, and probably different in other ways, too.
Scientists theorize that there could be at least two kinds of eyeball planets out there, and probably more. Hot eyeballs would be planets located close to their sun, where the sun side is totally dry because the heat has caused all of the moisture on that side to evaporate, and the dark side is one enormous ice cap — with a temperate ring caused by melting ice, in perpetual, unchanging twilight, separating the two sides. Icy eyeballs would be farther away from the star, where the dark side would be one huge glacier but the sun side would still have liquid water — perhaps with a few islands and continents thrown in for good measure, just to give the eye an even creepier appearance.
Today NASA celebrates its 60th birthday. The National Aeronautics and Space Administration was created when President Dwight D. Eisenhower signed the National Aeronautics and Space Act of 1958 on July 29, 1958.
NASA replaced the National Advisory Committee on Aeronautics, and President Eisenhower viewed the creation of the agency as an historic step, “further equipping the United States for leadership in the space age” and allowing it to make “an effective national effort in the fields of aeronautics and space exploration.” You can read the full text of President Eisenhower’s signing statement here.
It is not unusual for federal legislation to be hailed as historic when it is signed, but in the case of the National Aeronautics and Space Act that prediction was entirely accurate. I think it is safe to say that NASA has met, and greatly exceeded, the goal of allowing the United States to make “an effective national effort in the field of aeronautics and space exploration.” The Mercury, Gemini, and Apollo programs, the space shuttle and international space station, and the many unmanned probes and devices that have allowed us to better understand our solar system all bear the indelible imprint of NASA. NASA has taken human beings to the Moon and brought them safely back home and has given us up-close looks at Mars, Jupiter, Saturn, and their moons. NASA’s efforts have also helped to push advancements in science, technology, and other areas that have now become part of our lives and culture. By any measure, this still-sprightly 60-year-old has been a spectacular success.
Some people reflexively complain about the creation of any federal agency, but NASA is an example of how mobilizing an effort at the national level and entrusting it to knowledgeable people can accomplish great things. With private space exploration and travel looming on the immediate horizon, and Congress currently considering how to regulate those private efforts going forward, it will be interesting to see what the next 60 years bring for NASA — the little agency that could.
Forty-nine years ago, on July 20, 1969, the Lunar Module carrying Neil Armstrong and Buzz Aldrin landed on the Moon. Neil Armstrong stepped off a ladder onto the lunar surface, spoke his famous words — “That’s one small step for [a] man, one giant leap for mankind” — and history was made.
I was watching on that day, along with probably everyone else on the planet who had access to a TV set. I remember sitting with UJ and watching grainy black and white footage as the lunar module landed and then, later, Armstrong stepped into history. I was 12 years old. Even now, I still feel a little thrill just thinking about that day and that moment, when it seemed like anything was possible and it would be the start of a golden age of space exploration that would take human beings to Moon bases, Martian colonies, and on to the stars. Of course, that didn’t happen . . . but I still remember that awed and awesome feeling.
Let’s say your modest portfolio in the stock market has had a good run over the past year or so, and you’re looking for a new investment opportunity. Let’s posit, further, that you think Bitcoin is a curious bubble that’s going to burst someday, and that you’d rather put your money into a company that produces something more tangible and more futuristic.
It’s not easy for the casual investor. What we really need is for one of the stock exchanges to create a “space index,” just like there’s a Dow Jones “transportation index.” The index would identify the space-related public companies, mutual funds would be established to invest in each of the space index companies, and those of us who’d like to put our money in the heavens could buy into the mutual funds.
Hey stockbrokers! How about giving investors interested in space some help here?
Let’s pause for a moment, ignore the ugliness and failure that seems to boil out of the depths of Washington, D.C. on a daily basis, and consider for a moment something that everyone can agree America has done incredibly well: manned, and unmanned, space exploration.
Consider Voyager 1. It was launched 40 years ago, in September 1977, during the early years of the Carter Administration. With its sister probe Voyager 2, it successfully explored the major planets of our solar system, sending back fabulous pictures of Jupiter and the rings of Saturn and collecting data that gave us a better understanding of the two giants in the neighborhood of planets circling the Sun. I remember belonging to a group called The Planetary Society that supported space exploration and travel and getting some of the fantastic Voyager photos as part of my membership.
But then, Voyager 1 just kept going, and going, and going. It is now more than 13 billion miles away, and has officially gone past the boundaries of our solar system and is out in the trackless areas of interstellar space. And it’s still working, too. Recently NASA sent a message out to Voyager 1, instructing it to fire its trajectory correction maneuver thrusters for the first time since November 8, 1980, a few days after the presidential election in which Ronald Reagan beat Jimmy Carter. The Voyager flight team had to send the instructions in an outdated software language — imagine how much the computer world has changed since 1977! — and it took more than 19 hours for the instruction to reach Voyager 1, but the instruction worked, and the thrusters fired for the first time in 37 years. The firing of the thrusters allows Voyager to keep its communication antenna pointed in our direction and to keep sending us data as it moves farther out into the void.
It’s pretty amazing stuff, and Americans should be proud of this accomplishment and the planning, and engineering, and foresight that went into the Voyager program. Of course, we don’t hear about it, in the haze of coverage of presidential tweets and other current news — but it’s a noteworthy accomplishment just the same. Kudos to NASA!
Yesterday the SpaceX venture reached a new milestone: the company took a used rocket that it had recovered from a prior mission, relaunched it into space, deposited a customer’s satellite into orbit, and landed the rocket on a drone ship in the Atlantic Ocean so it can be used again, and again, and again.
As I’ve written before, private, commercial ventures like SpaceX are making significant progress in making space flight a common, everyday option. Yesterday’s flight was a key development in that effort, because a significant part of the cost of space flight has been rockets that are designed, built, and used only once. That single-use approach might have been viable back in the ’60s, when government funding was plentiful and the United States was on a national quest to be the first country to land a man on the Moon, but it’s simply not sustainable or feasible in our modern world of massive budget deficits and competing national priorities. It’s also an approach that commercial space concerns could never afford. That’s why SpaceX has been focused on developing technology that allows those expensive rockets to be reused.
No one should take away from the mighty, ground-breaking accomplishments of the Mercury, Gemini, Apollo, and space shuttle programs, and there remains a key role for governments in space exploration. Governments will always have more resources than businesses do, and the need for scientific exploration, and the technological developments that seem to inevitably accompany it, will often fall to governmental entities like NASA. But profit-making entities and capitalist risk-takers are adept at building on the foundation the government has laid and figuring out how to make things affordable and, not incidentally, profitable.
If tourist trips to the Moon and settlements on Mars are in our future — and I hope they are, because I still hold out hope that I might see a glorious Earthrise from the Moon some day — commercial concerns inevitably will play a huge role. SpaceX’s reusable rocket technology is another important step forward toward a future in which the “final frontier” becomes a much more accessible place.
Those of us who’ve been waiting patiently — for years, and years, and years — for the United States to get back into the manned space exploration mode have always thought that perhaps crass commercialism might be the impetus. If governments aren’t spurred by noble thoughts of advancing into the final frontier and exploring for the benefit of all mankind, maybe they’ll be motivated by cold hard cash. With a compelling case for a serious financial return from exploration, modern governments might — like the European nations exploring the western hemisphere during the 1400s and 1500s — be willing to commission a few ships, set sail, and see what they can find.
The asteroid, called 16 Psyche, is about the size of Massachusetts and has been battered by meteor strikes. It’s composed primarily of nickel and iron. The vast quantities of metal on the asteroid is a kind of treasure trove that causes NASA to say that 16 Psyche is worth about 10,000 quadrillion dollars. How big is a quadrillion? Well, apparently there are about one quadrillion ants on planet Earth. Multiply that mind-boggling number by 10,000, and you get the value of 16 Psyche. Even Bill Gates would be impressed by that sum.
Of course, we might not want to cart all of that metal back to Earth, because that would be pretty expensive. We might decide that the treasure trove would be better used to build settlements on Mars, or to manufacture space stations or space craft, or for any of countless potential uses of metal in space. And it’s all out there waiting for the first intrepid country, or group of countries, that is willing to go out and get it.
With all of the bad things happening in the world these days, it would be nice to turn our eyes skyward. I wouldn’t mind a little greed for $10,000 quadrillion if that’s what it takes to motivate us to get back into space to stay.
Tardigrades are extremely weird, extremely small creatures — but it looks like they’ve got a lot to teach us.
Tardigrades are eight-legged microscopic creatures that were first discovered about 450 years ago. They are undeniably ancient, having diverged from precursor animal species more than 600 million years ago. That makes them one of the oldest species on Earth. In close-up photos, they look like manufactured animals . . . or perhaps characters in a video game. They’re also called water bears, and some people curiously describe them as “adorable.”
Since it was dissed nine years ago, tiny Pluto has stolidly borne its politically incorrect “dwarf planet” label. Still, it’s an intriguing object. It’s tiny (smaller than our Moon), its orbit is different from that of any other planet, it’s unimaginably far away (on average, 3.6 billion miles from the Sun, 40 times farther away than Earth) and its deeply mysterious because we’ve never gotten a good look at it. Even though Pluto was discovered in 1930, we still don’t have any decent picture of the object.
That’s about to change. Recently, NASA’s New Horizons spacecraft entered its Pluto exploration zone. It was launched in 2006 and has traveled more than 4 billion miles to get near Pluto. For most of that time, the spacecraft’s active systems have been “sleeping.” Now, New Horizons has been awakened, and last Sunday it began to take its first pictures of Pluto. It’s closest pass will come in July.
As New Horizons transmits its photos back to Earth, we’ll learn far more about Pluto than we’ve ever known before. I’m rooting for little Pluto, which has basically been ignored in favor of studies of Jupiter, Saturn, and Mars. I’m hoping that Pluto turns out to be the most fascinating object in the solar system. Who knows? Maybe Pluto is small and weird because it’s not a planet at all, but instead an alien spacecraft, or a marker like The Object in 2001. Probably not . . . but a Plutophile can dream.
We all have to pay attention to the realities of the world — but it’s nice to take a moment now and then to dream. I firmly believe that our future ultimately lies in the stars, and sometimes I wish we did more to make that future come to pass. Aspirational projects like the one described in the article linked above might help to spur us in that direction.
India and China are competitors in a new space race. They are vying to join the United States, Russia, and Europe in showing the scientific and engineering capability to conduct complicated space missions and enhance their international prestige as a result.
As the Indian and Chinese missions show, there will always be a role for government in space. Many of us regret that the federal government didn’t ignore the naysayers and move much more aggressively into space after the triumphs of the Apollo program with the building of a large, functioning space station, lunar bases, and other efforts. But the government didn’t do so. Now those of us who dream of space exploration should be pleased that private enterprise sees opportunities in the heavens. The history of America has shown that capitalism can work wonders, and competition among companies can spur extraordinary technological advances. If the same visionary leadership and engineering savvy that produced our personal computer and smartphone revolution can be brought to bear on the commercial development of space, who can say what opportunities might be realized?
Keep your eye on the high desert. When we start reading more about readily available “space tourism” flights or mining efforts in the asteroid belt, we’ll know that the future envisioned in countless science fiction novels has moved a little bit closer.
Kirobo is 13 inches tall, is capable of various movements, and was modeled on the cartoon character Astro Boy. Kirobo is programmed to communicate in Japanese and to recognize the face of astronaut Kochi Wakata, so Kirobo can greet Wakata when they meet up at the International Space Station. The robot will record all of his conversations with Wakata and also may serve as a conduit for messages from the control room. Kirobo’s designer says he hopes the robot will serve as a kind of mediator between human and machine.
The Japanese are constantly breaking new ground in robotics, and Kirobo is just the latest development. Still, I wonder about the underlying concept. Our technology has progressed to the point where we routinely communicate with machines, through keyboards and voice commands, but an emotional connection just doesn’t happen. No one considers Siri their BFF.
Will a lonely astronaut, fresh from a hard day’s work on the ISS, really want to have a deep conversation with a doll-like invention that looks like Astro Boy? Would Mission Control be more concerned if the astronaut didn’t connect emotionally with Kirobo — or if he did? Is talking to a tiny machine really that much emotionally healthier than talking to yourself?
Curiosity‘s mission will be a long, and interesting, one that will last for at least two years. The rover is the largest device NASA has yet landed on Mars and is powered with a long-lasting plutonium battery. It will navigate the Martian surface, scan the Martian soil for signs of water, climb a Martian mountain, and collect samples to test for organic compounds, and pulverize rocks with a laser. And, because this is the social media age, Curiosity of course has its own Twitter feed. The rover therefore also has made history by sending the first Tweet from the surface of Mars. It said: “I’m safely on the surface of Mars. GALE CRATER I AM IN YOU!!!”
