Thank You, Guest Editor LeVar Burton

Image credit: Reading Rainbow

We at Scientific American share several passions with the actor, producer and educator LeVar Burton: fostering children’s literacy, science, social good and education. And, of course, Star Trek. So perhaps it’s only natural that this past Wednesday we welcomed Burton as our Guest Editor for the day. Burton conducted a “site takeover”—making story assignments, deciding [...]

How the Ansari X Prize Altered the Trajectory of Human Spaceflight

Looking up into the bright Mojave sky in 2004, I strained to keep my eyes on the tiny spaceship 50,000 feet up. “Three, two, one… release, release, release!” came the call over the loudspeakers. I held my breath as I watched the rocket motor ignite and the spaceship ascend on a plume of fire with [...]

Alien Yet Familiar: Following Curiosity Across Mars

(Mastcam image, Credit: NASA/JPL-Caltech/MSSS)

822 Martian days after landing, NASA’s Curiosity rover, carrying the Mars Science Laboratory, continues on its extraordinary journey across landscapes that are both utterly alien, and remarkably familiar. Here’s a small update. On November 18th 2014 the rover was in the center of this region (within the Pahrump Hills), continuing across the base area of [...]

That Comet? That’s You, 4.5 Billion Years Ago

As the European Space Agency’s Philae lander bounced and settled onto the surface of comet 67P/C-G’s crumbly nucleus it wasn’t just space exploration, it was time travel. This stupendous feat of spacecraft design and operation has brought us to a place little changed from its original state, a condensation and agglomeration of one small part [...]

The Surreal Task of Landing on a Comet

On November 12th 2014 the European Space Agency’s Rosetta mission will eject the small robotic lander Philae on a trajectory that should take it down to the surface of comet 67P/Churyumov-Gerasimenko (or 67P/C-P for short). Already Rosetta is maneuvering from its 10 kilometer orbit to get into the right place to deploy Philae. The landing [...]

Failure Is Always An Option

One of the lucky ones...Saturn V launch (NASA)

Do not try this at home. A Russian Proton-M launch goes wrong – and it can happen to anyone (wait for the shock wave). A rocket is a controlled bomb. The fully fueled Saturn V ‘moon rocket’ held an explosive force of about half a kiloton of TNT, enough to do some serious damage if [...]

Interview: The New Moon

moon

Think you know about the Moon? I did, but then I started reading ‘The New Moon: Water, Exploration, and Future Habitation‘ (Cambridge University Press, 2014) and realized that my knowledge amounted to a teensy scrap of lunar dust. For the past few years my colleague Prof. Arlin Crotts has been assembling an astonishingly detailed look [...]

New Horizons Mission Catches Pluto And Charon Waltzing

After a ten year journey, NASA’s New Horizons mission is still 420 million kilometers from the Pluto system – but that’s close enough to begin to see the orbital dance of an icy world and its major moon. This far out from the Sun it’s easier for planetary objects to hold onto satellites, so even [...]

Sneaking up on a Sweaty Comet

(ESA)

Over the coming month the European Space Agency’s (ESA) Rosetta mission will fire its main engines no less than eight times to tweak its interplanetary intercept course with Comet Churyumov–Gerasimenko; eventually sidling up to the 4 kilometer wide cometary nucleus at about 7.9 meters per second in early August. At that point, with some gentler [...]

Snow, a Slowing Planet, and a Last Dangerous Dance with Venus

20140516_Venus_Express_aerobraking_f537

                In about a month’s time, the European Space Agency’s (ESA) Venus Express spacecraft will adjust its orbit and dip into the outer venusian atmosphere. This hypervelocity skimming will allow scientists to not only obtain a little more data on Venus’s atmosphere, but to also learn more about [...]

‘Jade Rabbit’ is on the Moon

Sinus Iridum

At 1.11pm UTC today (8.11 am EST) the Chang’e-3 mission made a successful soft landing in an area toward the edge of the Sinus Iridum and Mare Imbrium – shown in this image by the red flag. That’s on the nearside of the moon – marked in a red ellipse in the figure below. Next [...]

The Great Martian Storm of ’71

(NASA)

                          On November 14th 1971 NASA’s Mariner 9 became the first spacecraft to successfully orbit another planet. Its video-camera imaging system powered up, and American scientists eagerly awaited the first detailed pictures of Mars since the flyby of Mariners 6 and 7 just [...]

What Interstellar Gets Wrong about Interstellar Travel

A starship travels through a cosmic wormhole

Christopher Nolan’s new film, Interstellar, is a near-future tale of astronauts departing a dying Earth to travel to Saturn, then through a wormhole to another galaxy, all in search of somewhere else humanity could call home. It’s a gorgeous, ambitious work, with outstanding performances from a star-studded cast augmented by high-fidelity visual effects and a [...]

Millionaire Plans Manned Mission to Mars in 2018

Mosaic of the Valles Marineris hemisphere of Mars

Yesterday, a mysterious group called the Inspiration Mars Foundation announced vague plans for a “historic journey to Mars and back in 501 days” scheduled for 2018. The group neglected to mention if the trip would be manned, instead directing the public to a press conference scheduled for February 27. But new information reveals that the [...]

Curiosity Gears Up to Zap Rocks in Huge Crater at Red Planet

Mars, rover

Now that NASA’s “seven-minutes of terror” have passed safely, the Mars Curiosity rover’s exploratory mission is off and running. Over the next two years—probably more, if it’s anything like the Opportunity or Spirit rovers—the Jeep-sized rover will explore its new home using a variety of tools. One of the Curiosity’s most important objectives will be [...]

Planetary Resources’ Crazy Plan to Mine an Asteroid May Not Be So Crazy

Vesta, asteroid, Dawn, space

In a widely anticipated announcement today, the new company Planetary Resources revealed their plans for near-Earth asteroid domination. The group has mapped out a multi-stage process to map, observe, capture, tow and eventually mine asteroids for valuables. “A single 500-meter platinum-rich asteroid contains the equivalent of all the platinum group metals mined in history,” reads [...]

Could a Balloon Fly in Outer Space?

Here’s the sort of crazy idea that animates our office conversation at Scientific American. It all started with my colleague Michael Moyer’s joke that a certain politician could build his moon base using a balloon: just capture the hot air and float all the way up. Ha ha, we all know that balloons don’t work [...]

New Museum Exhibit Invites Visitors to Smell the Moon, Nuke an Asteroid or Colonize Mars

NEW YORK CITY—”Beyond Planet Earth,” the slick new exhibit on space exploration at the American Museum of Natural History, is thoroughly modern. It has an augmented-reality iPhone app that produces hovering, three-dimensional animations. It has an interactive station where museumgoers can terraform a virtual Mars on a giant touch-screen to make the Red Planet habitable. [...]

T-minus 18 months and counting: Virgin Galactic and the future of space tourism

Twenty-five years ago when Sir Richard Branson (sans the "sir," at the time) called up Boeing and asked for a spare 747, few would have predicted the brash entrepreneur would so radically disrupt the formerly staid business of air travel. Perhaps folks had higher hopes for the former record executives’ feature film production debut at [...]
