NASA's indestructible Mars Exploration Rover Opportunity, still going strong after two hundred years, driving around on the terraformed former Red Planet

Opportunity’s Bicentennial

More than eleven years ago, on January 25, 2004, Opportunity, NASA’s Mars Exploration Rover, landed in Meridiani Planum. An identical rover, Spirit, landed three weeks earlier, on the other side of Mars. Both vehicles were expected to remain active for 90 Martian days, more or less equal to three months on Earth. The Martian climate would claim its toll, or so the mission planners feared. Although on Mars the sun shines more than six hundred days a year, the dust storms and large daily temperature differences would surely leave their mark. Indestructible Oppy But the rovers appeared to be more… Read More

Modified Mars Revisited

A few weeks ago I received an email from someone who asked my permission to use Modified Mars as a setting for a novel. Modified Mars is a project that I conceived eight years ago, and it’s about terraforming the world currently known as the Red Planet. Another Earth First a brief explanation for those who rarely or never read science fiction. Terraforming (literally earth formation) is the alteration of a planet in such a way that Earth organisms, including humans, can thrive there. Terraformers are especially interested in Mars for several reasons. The planet is not too big, not… Read More

Merry Christmars

For decades, I’ ve been putting a great deal of work into my Christmas cards. And sometimes into those of others. This year I made one by commission of Explore Mars, a (mostly) American non-profit organization that promotes Manned Mars exploration: The design and the text “Two Down, Mars and the Universe to go” is a reference to Neil Armstrong’s “giant leap for mankind” and the recent landing of the European spacecraft Philae on the comet 67P/Churyumov-Gerasimenko. Mars comes into view as the next big step. And after that there are a few hundred billion stars and their planets to… Read More

Terraforming for Beginners

Terragen is software for generating landscapes. Landscapes on Earth but just as easily on other worlds, as is shown for example by Kees Veenenbos. Years ago I loaded some elevation data from NASA’s Mars Orbital Laser Altimeter into Terragen and I did some experimenting. There is a new version of the program now, which was a good reason to take those old terrain data off the shelf again. Rocks and grass There is much more possible with Terragen, these days. In the old days only aerial views could be made somewhat realistic. But nowadays you can add rocks, grass clumps,… Read More
