Hypersonic flight

Less than a hundred years ago, the Wright Brothers made the first powered airplane flight. Next month, NASA will fly a whole new type of airplane, faster than anything that has flown to date: not just supersonic (faster than the speed of sound) but hypersonic (MUCH faster than the speed of sound). Of course, NASA …

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 …

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 …

John Glenn’s return to space

At 9:47 a.m. on February 20, 1962, John Glenn, 41, a U.S. Marine test pilot, strapped into the tiny Mercury space capsule known as Friendship 7, hurtled into space atop an Atlas rocket. In the ensuing four hours and 56 minutes he circled the Earth three times, then splashed down in the Atlantic ocean, 880 …

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 …

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 …

Space stations revisited

  Forget cosmic radiation, the solar flares, meteorites, re-entry: the real danger facing space exploration today is red ink. As governments drown in it, some space projects have had more narrow escapes than Luke Skywalker. Consider International Space Station Alpha. A space station is a permanent inhabited base in orbit. People have been talking about …

Apollo 11’s 25th anniversary

On July 20 we marked the 25th anniversary of an historic event: my 10th birthday. As it happens, on the same day we marked the 25th anniversary of the landing of men on the moon–the best birthday present any 10-year-old ever had. President John F. Kennedy told Congress on May 25, 1961, that the United …
