The Saga of NEAR

Monday, a plucky little spacecraft called NEAR, for “Near Earth Asteroid Rendezvous,” is going to attempt to make space exploration history. Back in February of 1996, the 805-kilogram spacecraft, a short, stubby cylinder with four solar panels forming a cross shape at one end, was launched to rendezvous and orbit the asteroid Eros, whose orbit …

Space stations, once more with feeling

  In his 1984 State of the Union Address, former U.S. President Ronald Reagan announced that the U.S. would build a space station, a permanently inhabited base in orbit. It’s a safe bet that Reagan would have been shocked and disbelieving had you told him that it would be 14 years before the first component …

Extraterrestrials

On the television program The X-Files, FBI agent Fox Mulder is always searching for proof of extraterrestrials, mostly by exploring old warehouses with his trusty flashlight and cell phone. But as an article by Ron Cowen in the November 1 issue of Science News points out, the real search for non-terrestrial life is taking place in university and …

Black holes

They were talking about black holes recently at the 189th Meeting of the American Astronomical Society in Toronto. New evidence of their existence was presented, along with evidence of black holes at the centers of three typical galaxies. This may prompt you to ask the question, “So what’s a black hole, and why should I …

Life on other planets

On the television program The X-Files, FBI agent Fox Mulder is always searching for proof of extraterrestrials, mostly by exploring old warehouses with his trusty flashlight and cell phone.

Aquarius

We’ve heard a lot recently about the Russian space station Mir and the new International Space Station. But most people don’t know about a third station designed to allow humans to live and work in a hostile environment–not space, but the sea. It’s called Aquarius, and recently a team of six “aquanauts” completed an eight-day …

Crickets in space

One of my favorite sketches on the original Muppet Show as “Pigs in Space,” in which the intrepid crew of the starship Swine Trek faced danger, excitement and bad writing while exploring the final frontier. As far as I know, no real pigs have yet flown into space, but many other animals have made the …

Asteroids

Most of the time, they’re harmless. Innocuous, really. They tumble along, minding their own business, not hurting anybody. But every once in a while–BOOM! “They” are asteroids, and when they go boom, it’s because they’ve run into something. When that something is Earth…well, you’ve got trouble with a capital T, and that rhymes with E, …

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 …

Sputnik

  This Saturday marks the 40 anniversary of one of the most pivotal events in 20th century science:  the launch by the late Soviet Union of Sputnik 1, the first artificial satellite. Nowadays, of course, we take satellites for granted:  we see photographs taken by satellites every evening on the news, we watch television signals …

Mir

I’m very much a child of the Space Age. I was born the year after Sputnik became the first man-made object to orbit the Earth, celebrated my 10th birthday on the very day that humans first set foot on the Moon, and turned 17 on the day that the first Viking lander set down on …

The Hubble Space Telescope

If you’re an astronomer, “Twinkle, twinkle little star” isn’t a cute bed-time song for children, it’s a nightly nightmare. Stars twinkle (and daytime skies are blue) because we live at the bottom of a thick soup of atmosphere that distorts our view of the heavens. Ever since Galileo, this has played havoc with observations of …
