Calendars and Clocks for Mars

A day on Mars consists of 24 hours, 39 minutes, and just over 35 Earth seconds. And there are about 669 of those days, also known as sols, in a Martian year. So, on the Red Planet, Earth clocks and calendars are useless. But what are the alternatives? People on Mars A calendar for Mars? Don’t you have anything better to do, Mr. Blok? Okay, I won’t solve current world problems like war, climate change, or barrel organ terror with it. But I’m an optimist; I believe that at some point, people will live on Mars. Perhaps many people, and… Read More

Seven Digital Space Art Paintings

Space art as a genre is older than you might think. As early as 1301, a certain Giotto di Bondone from Florence made a painting depicting Halley’s comet. But the big breakthrough didn’t come until the late 1800s, when science fiction writers like Jules Verne and H.G. Wells started writing books that needed to be illustrated. Space art pioneers like Chesley Bonestell, Pat Rawlings and Don Dixon used the tools available to them in their days: paint, charcoal, chalk, pencil. Today, space artists, not to mention filmmakers, use digital tools with which nothing is impossible. Miles long spaceships on which… Read More

Is There Really No Planet B?

It’s a popular theme in science fiction: the quest for a new Earth, because the old one is becoming uninhabitable, usually due to human interventions. The search, in other words, for planet B, a place to escape the self-inflicted crisis. Sometimes the idea is elaborated in a somewhat ironic manner, like in the unsurpassed Dutch series Missie Aarde (Mission Earth), in which the Netherlands take the lead because it’s the only country not under water thanks to its dykes. Sometimes it’s dead serious, as in the movie Interstellar, in which drought, dust storms and crop failures make the need for… Read More

Kim Stanley Robinson’s Mars Trilogy

The Mars trilogy by Kim Stanley Robinson is one of the highlights of American science fiction, as far as I’m concerned. Red Mars, Green Mars and Blue Mars were published between 1992 and 1996 and tell the future history of our neighboring planet over a period of almost two hundred years. In those two centuries, Mars is fully terraformed: transformed from a cold, dry, lifeless desert into a living world with seas, forests and cities. Not all main characters are happy with those changes: the battle between the Reds, who prefer to keep Mars as it is and the Greens,… Read More

Two planets on the beach

How big is Mars in relation to Earth? When making such a comparison, it’s always a good idea to include objects that everyone knows. At the beginning of this century, I sometimes put a two euro coin and a euro cent on the table as a scale model. The Earth is the two euro coin and Mars is the cent. And to extend the analogy a little further: Pluto is the little sphere on the cent. Analogy But since 2006 Pluto is officially no longer a planet. And I think it was about the same time that the euro cent… Read More

Building a Planetary Road Sign

There must be many of them: those funny signposts that indicate the direction and the distance to places that are usually quite far away. Tokio 9597 kilometers, Kinshasa 6379 kilometers, Mahabalipuram 8106 kilometers. Wouldn’t it be nice, I thought a few weeks ago, if there was a signpost like that showing the directions and distances for the sun, the moon and the planets? Why doesn’t such a planetary road sign actually exist? Of course I immediately knew the answer. The planets all have their orbits around the sun and the moon revolves around one of those planets: the Earth. And… Read More

Chasing Elon Musk in an old French car

On February 6, 2018, SpaceX, one of the companies owned by Elon Musk, managed to launch the first Falcon Heavy. A giant leap for mankind, like Neil Armstrong would have said. Because with this rocket, manned missions to the Moon (once again) and to Mars become possible. And those missions also become a lot cheaper than before, because large parts of the rocket return to Earth and can therefore be used again. Starman On such a first test flight you don’t take expensive satellites. Usually a block of concrete is used as ballast, but Elon had a better idea: he… Read More

87 Members of the Solar Family

A while ago I made a family portrait of the solar system. Or rather a portrait of the leading members of the family, the eight planets: Jupiter, Saturn, Uranus, Neptune, Earth, Venus, Mars and Mercury. Moons, asteroids and dwarf planets But there’s more happening around the Sun. Moons for instance; our own Moon, of course, but also a large number of satellites of the four gas giants. There is an asteroid belt between the orbits of Mars and Jupiter where, besides a lot of little ones, also bigger objects are turning their rounds. But many asteroids can be found outside… Read More

Mars 2.0 – Return to the Red, Green and Blue Planet

The terraforming of Mars is a fascinating subject. Is it possible to transform that lifeless desert planet into a living world with seas and jungles? Can some other colors, especially green and blue, be added to the Red Planet? In any case, now that we are dangerously warming our own planet, terraforming is no longer a theoretical concept. Mars Society Netherlands The Red Planet and I have a long history together. In 1999 I founded, together with Arno Wielders (currently involved in Mars One) the Dutch chapter of the Mars Society in a café in Leiden. In the first years… Read More

Portrait of the Planets

When you want to capture the whole Solar System in one image, you come across a problem. The distances between the eight planets and their star are huge, almost unimaginable. In all the pictures of the solar system you’ve ever seen the sizes of the planets are wrong: they are strongly exaggerated, by necessity. On a scale model of about two metres – a nice size to hang on the wall in your living room – the Earth would be only four thousandths of a millimeter. You wouldn’t even be able to see our homeworld! Heaven on Earth The only… Read More
