Selling the moon

Humans will return to the moon next year, more than 30 years after the last Apollo astronauts left. Unfortunately, the new lunar visitors will have a large handicap that will hinder their exploration efforts: they’ll all be dead. The humans in questions will arrive in the form of small amounts of ashes from cremated remains, …

Space: what’s NExT?

I’m a child of the Space Age, born a year and a half after Sputnik. Apollo 11 landed on the moon on my 10th birthday; Viking landed on Mars on my 17th. There is no doubt in my mind that if the human race is to survive, we must move out into space, to make …

Extrasolar planets

The idea that planets orbit most of the stars in the universe has such a firm hold on our imagination, thanks to Star Trek and Star Wars, that most people are surprised to hear we only found the first planet outside our solar system in 1995, and proof of other solar systems (stars with more than one planet …

Space propulsion

  It’s been more than 40 years since Yuri Gagarin became the first human to orbit the Earth, and, in the process, traveled faster than any human before.  Today, we continue to send humans into orbit…where they travel at pretty much the same speed.  Oh, sure, unmanned spacecraft have traveled much faster, and so did …

Taikonauts

  On April 1, a spacecraft capable of carrying three people into orbit returned safely to Earth. That may not sound like news after 40 years of manned spaceflights, but this was a very special spacecraft: it was Chinese. Shenzhou (Heavenly Vessel) 3 carried instrumented mannequins instead of humans, but its success makes it more …

Drilling on Mars

You hear a lot about space technology being adapted for use on Earth–many of the high-tech marvels in fields as diverse as meteorology and medicine wouldn’t exist if not for the space program–but the Canadian Space Agency is doing the opposite: adapting Earth technology for use in space. The CSA has taken the first steps …

Canadians vie for the X-Prize

Human beings have been going into space for 40 years, riding vast amounts of U.S. or Russian government money, poured into massive rockets that are mostly thrown away after one use. But many people think this is a terrible way to go into space. If we want to make space truly accessible (at a cost …

Mars in the Arctic

A unique construction project finally overcame delays and disaster last week to take shape in the Arctic. It looks more or less like an oil tank, but in fact it’s a model of the kind of habitat humans may one day live in when they visit Mars. The two-story fiberglass structure is the brainchild of …

Missions to Mars

Thursday, September 23, 1999, wasn’t a good day for NASA. At 5:01 a.m. EDT, the Mars Climate Orbiter, a $125 million (U.S) space probe intended to observe Martian weather for two years, fired its engines to enter orbit around Mars and dove behind the planet. It never reappeared. After several hours of study, NASA announced …

Adapting to space

In the movies, spaceships have artificial gravity, because it’s a heck of a lot easier to film that way. Real-life astronauts aren’t so lucky. The men and women who inhabit the Mir space station spend months in weightlessness. Sure, it’s a lot of fun–flying around, leaving objects hanging in mid-air–but inside those cosmonauts’ and astronauts’ …

Liberty Bell 7

On July 21, 1961, Virgil Ivan “Gus” Grissom, 33, a decorated fighter pilot, was strapped into the tiny Mercury space capsule he’d nicknamed Liberty Bell 7 and launched into space aboard a Redstone rocket. The U.S.’s first manned spaceflight, Alan Shepard 15-minute sub-orbital flight, had occurred just 2 1/2 months before. Grissom’s mission was nearly …

Rockets

I have vivid memories from when I was a kid in Texas of travelling out into the countryside to watch my oldest brother and his friends launch rockets. This wasn’t some ’60s radicals’ attempt to overthrow the government of Swisher County, but a new hobby called model rocketry. The rockets came in all sizes, from …
