Category: CE 2021

It has been a remarkable year—no matter what the arena: politics, medicine, rocket science, exploration of the universe, and the list goes on.

We began this inaugural year of the CE 2021 Blog with remarkable engineering feats (Obliterate The Box: Three Spectacular Feats Of Rocket Science) including the landing of Perseverance on Mars. Several weeks later, we had the thrill of watching Ingenuity take off (Ingenuity Takes Flight and Fires the Imagination), establishing the first flight of an aircraft on another planet. Ingenuity has flown seventeen more times (as of today, December 30, 2021) and established new capabilities—terrain mapping, scouting for the rover, going where Perseverance could not. If you’d like to keep up with Ingenuity, check out the blog site or the flight log.

Perseverance has established firsts of its own: collecting core samples and exploring and analyzing the floor of the Jezero crater, most notably the Séítah region, characterized by sanding ripples. (For some fun, check out the Flash Series: Mars vs. The Invaders in which the Séítah region figures prominently.) Along the way, Perseverance photographed a sunset for the first time. Follow Perseverance at the mission blog site and stay up to date. Catch the weather report at https://mars.nasa.gov/mars2020/weather/.

And let’s not forget about Curiosity, which has been diligently pursuing its mission since it landed on August 6, 2012 (EDT). Load this link to your smartphone and you can get regular weather reports [https://mars.nasa.gov/msl/weather/]. Check out other links on the site to learn what Curiosity has been up to.

In the year we covered a Chinese Mars mission (https://en.wikipedia.org/wiki/Tianwen-1), electric race cars, hyper-loops, rockets, and lunar and Martian habitats. Based on responses from readers, the most popular post was the Dancing Robots (Tripping the Light Fantastic: Take a Robot as Your Partner).

This brings us to the year-end’s remarkable achievement—launching the James Webb Space Telescope on December 25, 2021. The telescope will look back to the earliest times of the birth of the universe. The launch was exciting to watch, but the progress of the mission until the telescope is on station will be a nail-biter. I’m tense, and I’m just watching. I can’t imagine how the mission team sleeps at night. But my guess is they are tense but have confidence in the engineering (and testing) that went into this remarkable accomplishment. If you’d like to stay up to date on the mission, save https://jwst.nasa.gov/content/webbLaunch/whereIsWebb.html to your smartphone home screen and check in every so often. My current obsession is checking in every five minutes, it seems. But then again, at its current velocity, it’s traveled over 150 miles in those five minutes—who knows what can happen.

Leave a comment and let me know what you think. What was your favorite post of the year? Will you be following the progress of the Mars mission and be watching anxiously for the new telescope to get into position and begin sending back pictures and data?

I know I’m looking forward to an exciting 2022.

Christmas. It’s a time of year we can embrace with joy or dread, for a simple reason—will we ever resolve the question: Is Die Hard a Christmas movie?

This year it got just a little more complicated. As this question started popping up on Twitter (and I’m sure other forums and in real life), the SyFy channel offered up a Die Hard marathon under their Christmas Movie branding. One might think the question of Die Hard as a Christmas movie was settled if you subscribe to SyFy as the arbiter. But no, it just complicated things—is Die Hard a science fiction movie? After all, the SyFy channel might think so.

Let’s consider which Science Fiction movies are unequivocally Christmas movies. That’s where I started my “research” for this post. And you know what I found? Not much. There are lists of movies that came out around Christmas and movies that take place around Christmas. One such list includes such offerings as:

Brazil

Prometheus

Gremlins

Children of Men

Rare Exports: A Christmas Tale [The list makers confess this is more horror than Sci Fi]

Santa Clause Conquers the Martians

But there is a real lack of movies about Christmas that are also science fiction. No android Santa’s or robot reindeer. No rocket-powered sleighs or time-stopping machines. No transporter beams for families without chimneys. And certainly, no aliens co-opting Christmas for their nefarious schemes. The closest we get is the last one on the list.

So, I’m going to go with Santa Clause Conquers the Martians. It’s tuned right into my B-movie obsession, and what’s not to like: Santa, cute kids, Martians, weird 60s Sci-Fi costumes, cheesy sets—the list goes on.

Synopsis from IMDb: Worried that their children have become obsessed with television shows from Earth which extol the virtues of Santa Claus, Martians begin an expedition to Earth to kidnap the one and only Santa Claus. While on Earth, they kidnap two lively children that lead the group of Martians to the North Pole and Santa Claus. The Martians then take Santa Claus and the two children back to Mars with them. Voldar, a particularly grumpy Martian, attempts to do away with the children and Santa Claus before they get to Mars, but their leader Lord Kimar stops him. When they arrive on Mars, Santa Claus, with the help of the two Earth children and a rather simple-minded Martian lackey, overcomes the Martians by bringing fun, happiness, and Christmas cheer to the children of Mars.

[Ref: https://www.imdb.com/title/tt0058548/?ref_=vp_back]

But discovering Rare Exports and watching the trailer has me intrigued. I’ll need to check out where I can watch it and see what it’s all about.

Synopsis from IMDb: “On Christmas Eve in Finland, Santa Claus is unearthed in an archaeological dig. Soon after, children start disappearing, leading a boy and his father to capture Santa and with the help of fellow hunters, they look to sell him back to the corporation that sponsored the dig. And then there’s Santa’s elves, who are determined to free their leader…”

[Ref: https://www.imdb.com/title/tt1401143/ ]

It doesn’t seem then that this post will resolve the question of Die Hard as a Christmas movie. If you apply the criteria from www.thelastthingisee.com (above), I would say Die Hard is. But you’ll never convince me it’s a Sci-Fi movie. The SyFy channel, I think, is stretching it. But I’ll keep watching.

Leave a comment and let me know what you think.

The year is wrapping up. Only twenty-four days until it’s 2022, but we still have Christmas to look forward to, and celebrate if that is your tradition. In the two grand traditions of American TV, my final two posts in 2021 will be “the Christmas episode” and “a look back at the year.” Watch this space, as they say.

But today I thought we take yet another side-step into a topic that is science fiction related, but not overly academic—phrases that have crept into everyday use to a greater or lesser extent.

After a bit of brainstorming, here are a few that I think I use occasionally, except maybe #4 and #6. Not because I don’t like them, or their source material, the need just never seems to arise. I’m guessing others use them, or maybe not.

How many do you use? Do you recall where the phrase came from? Answers are at the end.

1. May the Force be with you. [Confess: you use this, don’t you?]
2. I’ll be back. [Won’t we all at some point?]
3. Live long and prosper. [The geek in me pulls this one out now and then.]
4. May the odds be ever in your favor. [Loved the movies. Haven’t read the books.]
5. Beam me up, Scotty. [I know, I know. He never actually says this.]
6. The truth is out there. [Maybe those UAF (Unexplained Aerial Phenomenon)?]
7. Danger, Will Robinson. [A throwback to the original.]
8. Make it so. [Wouldn’t we like to have that authority?]

A related topic is the generation of new words, or neologisms. In doing a bit of reading, it surprised me how many common terms we associate with science, came from science fiction. Ranging from spacesuit to graviton, science fiction has contributed some familiar words to our language of space and space exploration. I commend the following article to your attention.

Sci-fi is a fertile breeding ground for neologisms: some have entered everyday language and even scientific jargon

By Pisana Ferrari at https://www.capstan.be/sci-fi-is-a-fertile-breeding-ground-for-neologisms-some-have-entered-everyday-language-and-even-scientific-jargon/

Answers, but I’m sure they were easy:

1. Star Wars
2. Terminator
3. Star Trek
4. Hunger Games
5. Just a cool saying, sort of from Star Trek
6. The X-Files
7. Lost in Space
8. Star Trek: The Next Generation

Clearly, I’m a Star Trek/Star Wars guy. No apologies.

What do you think? Do you have some favorites? Any you’d add to the lists that you use? Any that just annoy you?

At long last, Isaac Asimov’s galaxy-spanning epic comes to life as Foundation. I was excited to watch episode 1, The Emperor’s Peace. It was fantastic. Big effects, a plot against the empire, a massive space elevator, an entire planet as a city—I could go on. If you can, I would encourage you to watch it, especially if you’re a fan of the novels. I’m avoiding the temptation to binge-watch the rest of the episodes, but I need to pace myself and savor every hour.

Watching it got me thinking. A good number of the series are high drama, man against the evil empire (or corrupt corporations)—tense and engaging. Believe me, I’m a big fan of The Expanse, Dark Matter, and now, Foundation. But what about the lighter side? What’s out there that gives you a good belly laugh, or a sense of fun?

Brainstorming a bit, it was easy to come up with some favorites: Mars Attacks, Galaxy Quest, and one of the best, Space Balls. In a previous post, (Monster Movies–Are They Science Fiction? The Argument Rages On), we considered whether monster movies are science fiction. If some are, then I would include Young Frankenstein on the list of Science Fiction Comedies—a totally funny movie.

[Poster Source: https://www.ebay.com/itm/SPACEBALLS-Mel-Brooks-Movie-Poster-A1-A2-A3-A4-Sizes-/321438740053?_ul=IN]

 Science Fiction Comedies might fall into several broad categories, a couple of which are spoofs and comedies in their own right. Spaceballs I would put in the spoof category as it took so much from Star Wars. And Mars Attacks spoofs just about every Mars invader movie—although the opening barbecue scene ending in burning cows might be one of a kind. (Mars Attacks Opening)

 [Poster Source: https://www.rottentomatoes.com/m/mars_attacks]

What about Young Frankenstein? spoof? original comedy? funny actors in a “serious” story? All I can say is, every time Taco’s recording of Puttin’ on the Ritz comes on, I can’t help but see the dance number by Gene Wilder and Peter Boyle. Absolutely hilarious. The fabulous comedy actors made it superb.

Finally, relying on our trusty Internet to provide lists, we find there are more comedies than you might imagine. I checked out 10 Best Sci-Fi Comedy Movies That Blend The Genres Perfectly [sic]. I have not seen a few on the list. One more item on the to-do list for this winter—watch ‘em all. Maybe a long weekend after a snowstorm.

IMDB (the Internet Movie DataBase) of course has a list of The Top 50 Best Sci-Fi Comedy Films. Again, I’ve not seen some of these, but many I have. It was nice to see Star Trek IV: The Voyage Home on the list. One of my favorites, right after Star Trek II: The Wrath of Kahn (clearly not a comedy).

So, it looks like this winter will be full of fun, catching up on some favorites and enjoying some new titles.

What do you think? Do you have some favorites? Any you’d add to the lists that made you laugh? Any movies on the lists that aren’t so funny?

As I was thinking about what to write this week, I found myself sitting in my office—staring at blank walls.

Sure I have the bookcases, but nothing is hanging on the walls art-wise. I’ve been reluctant to commit to anything, considering I’m not sure what’s the right direction for a budding science fiction writer.

A few years ago, I attended Worldcon 76, the science fiction conference held that year, 2018, in San Jose. One of the presentations was on the art of Chesley Bonestell.

[Image Credit: https://www.bonestell.org/getattachment/509c3ea4-3770-4a5e-b85d-417606bc7f2f/Saturn-as-seen-from-Titan-(1).aspx]

Bonestell’s works were visionary and remarkable, considering many of his works, such as the one to the right, were produced before we’d sent any interplanetary probes or visited the Moon.

That would be a great way to set the tone for my office. Unfortunately, Bonestell’s works are not available for home exhibition. I had to move on.

Then there are the many pictures of rockets, shuttles, and satellites that I’d snapped at various museums when I was on vacation. But to be honest, I’m a lousy photographer. So could I find pictures of satellites that NASA shares, such as this image of Mariner 2?

[Image Credit: https://encrypted-tbn0.gstatic.com/images?q=tbn:ANd9GcSp8ZibPKxBjik2NicSc7Szo6D3zqDkYAvmkQ&usqp=CAU ]

But then—these are science fact rather than science fiction. Don’t get me wrong, they would inspire, but is there something else out there?

As we’ve found before, the Internet being what it is, there are lists of the best in Science Fiction art. One list is Greatest Sci-Fi Artists of All Time. The art on this site is beautiful, compelling, and tells a story when you let your imagination run wild a bit.

And—Science Fiction art has been around for a while. One collector has assembled cover art going back as early as 1908. Check it out at Classics of Science Fiction Art.

Finally, the site: Sci-Fi, Fantasy & Horror Art. brings together the work of many artists, and their work is fantastic.

[Image Credit: https://www.scififantasyhorror.co.uk/wp-content/uploads/2021/09/mohamed-reda-sci-fi-workshop-feature.jpeg]

The final possible source of décor might be photographs and images of actual natural phenomena—planets, moons, galaxies, and nebulae. I’ve considered the famous picture of the Earth “rising” over the Moon by Apollo 8. Pair that with a photograph of Moon-rise from the International Space Station, and I might have what I need.

[Image Credit – Earthrise: https://encrypted-tbn0.gstatic.com/shopping?q=tbn:ANd9GcSFOOqWlaDvmOkj7aCUbod1CPdR-5x0i7FYHYWjNvuNH-1VC5CC2UZGW7ha2orqm75ElKj7ZjEAUUA&usqp=CAc]

Where did I end up? With blank walls and too many ideas. At least I’ve done some investigation and have some thoughts on what’s next—another task for the winter months ahead—a Science Fiction Rock Playlist and artwork for the walls.

What do you think? Do you have some favorites? Should I go with all Science Fiction art? Maybe a few planet and nebula pictures? How would all rocket ships or all aliens look?

Leave a comment and let me know what you think. I’ll share the results in a future post.

Thanks for stopping by.

This week we’re going to return to the general category of fantastic science, engineering, and technology feats that I first marveled at in the post from March 29, 2021 (Obliterate The Box: Three Spectacular Feats Of Rocket Science).

But this week, we’re going interstellar.

Interstellar? You might ask. Humans aren’t traveling in the vastness of interstellar space—or are we? OK, so maybe humans aren’t, but our machines are, and that’s where we can marvel at the spectacular feats of science, engineering, and technology.

Voyager 1 and Voyager 2 are sailing the interstellar realm. I follow both on Twitter, and it occurred to me, beyond the novelty of space probes having Twitter accounts, that the reports give us their distances in light-seconds. For example, the Monday (10/4) tweet from @NSFVoyager2 [unofficial account] reported that Voyager 1 (@NASAVoyager [official NASA account]) is 21 hours, 24 minutes, and 49 seconds of light travel from Earth, and adding 11 miles to that—every second. Voyager 2 is a little closer at 17 hours, 45 minutes, and 33 seconds of light travel from Earth.

Think about that for a moment. We frequently measure things compared to the length of a football field, try to wrap our heads around the Moon being a quarter of a million miles away, or talk about Mars being at its closest to Earth at about 39 million miles. It’s hard to imagine something so far away that we need to measure that distance in how long it takes light to travel there. By comparison, light from the Sun takes about eight minutes to get to Earth. It takes that light five and a half hours to reach Pluto. That same light takes almost a whole day to get to Voyager 1.

Fantastic also that Voyager 1 and Voyager 2 are still doing science, sending scientists information on the interstellar plasma. The hope is that Voyager might still be doing it when it’s 50 years old in 2027. Voyager 2 may not be able to power a science instrument but may continue to transmit a weak radio signal through the middle of this decade.

One last note, the probes are expected to continue on their journeys for who knows how long, reaching the Oort Cloud in something over 300 years, close to another star in 40,000—unless one returns home before then. We know how this movie might end.

The danger was real, and it was only through Spock and Kirk’s quick thinking that Earth’s annihilation was avoided, and V GER met its creator. (OK. OK. It was a not-real Voyager 6, not one of these. But, who knows what’s out there.)

A couple of weeks ago, a friend of mine sent me a link to an NPR article about NASA looking for volunteers to live in a test habitat for a year. (NASA Wants You To Spend A Year Simulating Life On Mars, For Science). I had planned to write about that this week. But I think I’ll leave it for next week. Go ahead and read the article, and I’ll cover the topic in my next post.

Why not this week? Because—Boston Dynamics has released another robot video and Twitter lit up a bit about using these robots on the Moon. And it got me thinking about how we might use robots to prepare for human exploration and ultimately colonization of the solar system, and dare I say—the galaxy.

You may remember a few months ago when the Dancing Robots entertained us (Tripping the Light Fantastic? Take a Robot as Your Wingman). The dance moves were impressive, and the routine was, of course, a joy to watch, particularly if you like ‘80s music.

The latest video, Atlas | Partners in Parkour, highlights some equally impressive acrobatics. The question bantered about Twitter was whether we should take one of these on the Artemis missions to the Moon. We could speculate about their use. Reconnaissance was mentioned. But you could also imagine moving supplies and equipment, assembling machinery, constructing habitats, maybe even search and rescue!

And that brings me back to the topic of who will be first to explore and settle extraterrestrial planets—humans or robots? In his three robot mystery novels (The Caves of Steel, The Naked Sun, and The Robots of Dawn), Isaac Asimov addresses how we colonize other planets. The Spacer camp wants us to send robots to build a human-ready environment and then move in—comfortable, low risk, easy. The Settler camp wants new colonization to be conducted by humans—uncomfortable, dangerous, challenging. I won’t reveal the answer—no spoilers—you’ll need to read The Robots of Dawn.

But we’re already asking a similar question—why do we need to send people on the dangerous mission to explore other planets? Can’t we use robots to do it? And now that we’ve seen what the Boston Dynamics robots can do why not send them (or a version of them)?

In some respects, we’re already using robots to explore. Curiosity and Perseverance are robots conducting activities and completing tasks millions of miles away on Mars in an unbelievably hostile environment. Yes, they’re following instructions, but with no real-time human intervention. But that can’t be all we do. We need to explore and learn, and, yes, we need to understand the challenges before we go—but go, we must. Will we ever really know what another planet is like (or the Moon for that matter) until someone stands there and looks to the distant horizon and wonders what’s over there?

So, what do you say? Ready to head out to the planets and do some exploring? Should we risk people’s lives or just let the machines do it? Leave a comment and let me know what you think.

In future posts, we’ll explore the next step: Colonization.

[Disclaimer: Please accept my apologies for any ads that pop up before the linked videos. They do not reflect my position, nor do I endorse any of the products – it’s just a YouTube thing I can’t get around.]

Much has been made of Sir Richard’s trip to the edge of space. Even with all the testing, the practice runs, the safety protocols, etc., it must have been a heart in the throat, white knuckle trip. The video from the cabin looked like they were having a great time, though. Of course, we didn’t see what the pilots were doing, but passengers looked like they were glad they made the trip. (In Cabin Video, about a minute in is the weightlessness part).

Thinking about that trip, I did some reading on what’s next. Mostly what I found was what’s next for Virgin Galactic and the expected comparisons to Blue Origin. Discussions of space tourism, lowering the costs of tickets, more frequent flights, and, of course, the safety of it all was the predominant material.

But there were a few that branched into sub-orbital transportation. We’re no stranger on this site to discussing suborbital transportation as we addressed this topic back in May (Breakfast in New York – Lunch in Singapore – Dinner in London). To the novice (me), it seems that the Virgin Galactic might have a workable model for small groups of passengers (or those that are reluctant to strap into a rocket).

What I learned was we’re a long way from hypersonic or suborbital transportation. Wired’s interesting article from 2018 summarizes the challenges and where we are relative to past advances in aeronautics and passenger air travel.  Check it out. (Forget supersonic, the future of super-fast flight is sub-orbital)

But what about this concept of a business that takes passengers to space, if even for a short time. Some commentators have objected to billionaires using their wealth to take other wealthy people on a joy ride. One article estimated that Jeff Bezos liquidates $1 Billion in Amazon stock per year to fund Blue Origin (Blue Origin Auctions Seat on Bezos Rocket for $28 Million). Another way of thinking about that is that $1 Billion goes to pay for materials, services, salaries, benefits, etc., for Blue Origin as an enterprise. Further, if Virgin Galactic delivers all its 700 booked flights at $250,000 each, they’ll earn $175 Million. If there’s a profit margin there, isn’t that what commerce is about, finding a product that people will buy. I know it’s not as simple as that, but it’s a conversation to have.

And as far as the joy ride part, consider how much is spent on amusement parks. One estimate has the cost of building Disney World at $6 to $7 Billion in today’s dollars. But I’ve got to tell you, that was money well spent—Disney World is a great trip.

So we can’t all go to space, but some can, and that endeavor employs people in well-paying high-tech jobs. But many of us can go to Disney World, which also supports many well-paying, high-tech jobs.

What do you think? Are the space tourism efforts ill-advised? Does your thinking change if you consider the economic benefits? Are they just souped-up (albeit expensive) amusement park rides?

Leave a comment and let me know what you think.

Thanks for stopping by.

Blue Origin Update July 26 – A quick update was in order with the launch of Blue Origin’s first passenger-carrying rocket. Certainly, a different way to get to space than Virgin Galactic’s and others can debate if both or either of these trips got the passengers to space or not. Regardless, the Blue Origin launch puts one more private firm in the business of reusable boosters. Say what you will about taking wealthy passengers on joy rides to space (see my comments above). Still, his endeavor should be expected to add to the industry’s abilities in developing hardware, software, and processes needed to make reusable boosters safe and cost-effective.

[Disclaimer: Please accept my apologies for any ads that pop up before the linked videos. They do not reflect my position, nor do I endorse any of the products – it’s just a YouTube thing I can’t get around.]

First, I’ll confess I am not an expert in orbital mechanics by any stretch of the imagination—not even close. I don’t purport to be one, nor have I ever played one on television.  So what follows is an amateur’s attempt to consider what it might take to get to Mars quickly.

I do, though, appreciate the simplicity of some of the equations that describe the mechanics of motion in our typical, everyday, non-relativistic (i.e., no Einstein in today’s post) universe. For example, in high school physics, I remember that the distance traveled from a standing stop is one-half the acceleration times the time squared (d = ½ a t2), where d equals the distance traveled, which equals the distance traveled acceleration and t equals the time.

So, what does this have to do with getting to Mars? Well, I thought I’d share a simplistic view of how to get there in a hurry. The equation tells us that even for vast distances, we can get there in a hurry if we can constantly accelerate. Imagine 0 to 60 in 4 seconds in a car—what if you kept going? You can get a sense of just how fast you’d be going in a relatively short period.

But before we go there, we might pause to consider that current plans to get to Mars involve journeys of seven to nine months or longer. This trip uses a tremendous amount of thrust to accelerate a space vehicle and get it started on its way. Then the spacecraft coasts for months. When it arrives at the Red Planet, it again expends fuel to slow down and either enter orbit or land. This is how Perseverance traveled to Mars, as did the array of landers and orbiters that are currently operating on and around Mars.

The question becomes, how would the journey to Mars change if we could continually accelerate for the whole trip. Those of you who are science fiction fans are likely familiar with The Expanse series. In that universe, the Epstein Drive provided constant acceleration. (Here’s some fan fiction: https://expanse.fandom.com/wiki/Epstein Drive.) If you watch the series, it appears to be 1 g (one Earth-normal gravity) since they walk around the ships normally.

That technology doesn’t exist—yet. Are we getting close, though, to constant acceleration at a lower level? That’s hard to say. But what if we could accelerate a ship at just 1/1000 of the force of gravity?

In that instance, and assuming we traveled to Mars when it was at its closest, the trip could be on the order of a couple of months. If we could accelerate at 1/100, it would be weeks. (Rocket scientists are very welcome to correct my math and assumptions.) Imagine a trip to Mars in a month. Colonization might seem more realistic. Return trips to Earth for a visit by Martians might be feasible. Maybe—a vacation at Olympus Mons or Utopia Planitia.

Regardless, as space technologies advance and we find new and different ways to build and move spacecraft, getting to and from Mars quickly might not stay a science fiction fantasy. In our lifetime, we just might see quick trips to our neighbor.

Let me know what you think? Would you go on a cruise to Phobos and Deimos with a stop at Jezero Crater to visit where NASA searches for past life on Mars? It might be fun.

Thanks for stopping by.

With the possibly inexorable move away from fossil fuels, we’ve been looking at various methods of transportation that will need to be different when they go electric. In April, we looked at high-speed rail and hyperloop, both electric-powered, as possible replacements to air travel (Riding High-Speed Rail or Shooting through a Hyperloop Tube). During June, we’ve looked at Formula I Racing (Drivers – Start Your Motors…) and electric airplanes (Electric Planes – the Future of Air Travel? …).

But what about rockets? The immense power of modern rockets is a thing to behold (Saturn V). I’ve watched any number of launches by SpaceX, Rocket Labs, ULA, etc., and am constantly amazed that science and engineering have harnessed such forces. I can’t wait for the first launch of the Space Launch System vehicle being assembled in Florida for the Artemis 1 mission.

Smaller rockets and thrusters using different technologies, but operating on the same Newtonian principles, move spacecraft once they are in orbit. And rockets propel probes, landers, and now a helicopter, millions, if not billions, of miles across the solar system to orbit planets and asteroids and land on Mars and the Moon, for example.

How much of this could be and will be replaced by electric rockets?

As it stands now, no electric-based technology exists that would lift heavy payloads off the Earth and into orbit. However, hundreds of probes and satellites are currently using electric thrusters to maintain positions and maneuver. Electric thrusters have been in operation since the 1970s, and NASA is looking at options for using nuclear electric engines to send astronauts to Mars (Nuclear Propulsion Could Help Get Humans to Mars Faster).

One advantage of nuclear electrical propulsion is the ability to propel the spaceship under constant thrust. Chemical rockets like the videos above use all their fuel in a relatively short time but get the spacecraft moving at the high speeds needed to escape the Earth’s gravity and get to where they’re going. Electric propulsion puts out less thrust but can run for a longer time. This could shorten the travel times by quite a bit.

Imagine getting to Mars in a few months or even days. Think of an immense spaceliner, like an ocean liner, which stays in space and travels back and forth between Earth, the Moon, Mars.

Would you go for a visit?

Next week we’ll look at some of the transit times and do a little retrospective on how these questions have been addressed in fiction. Stay tuned.
