NASA Begins Countdown to Spirit's Arrival on Mars
Spirit – the first of NASA's two robot geologists en route to the red Planet -- is “in “excellent” health, NASA and JPL scientists reported at a news briefing at JPL this afternoon, and the countdown to touch down on the Red Planet has begun.
No Icecaps at the Lunar Poles
New observations reported this week in the journal Nature have cast doubt on the theory that thick deposits of ground ice lie conveniently close to the surface in permanently shadowed crater floors at the lunar poles.
Researchers Discover Lakes on Titan
Recent radar observations of Saturn’s moon Titan have produced the first direct evidence that the second largest moon in the solar system may be hiding pools of liquid hydrocarbons underneath its smoggy atmosphere.
Cassini Captures Its First Image of Saturn
The Cassini spacecraft has captured its first image of its target planet, Saturn.
Voyager's Last View
Home. Family. This will be Voyager's enduring legacy: It has changed forever the feelings raised by those words. Through its robotic eyes we have learned to see the solar system as our home. Through its portraits of the planets we know that they are part of our family. Apollo astronauts showed us a tiny Earth alone in the blackness of space. Now, with these images, Voyager has shown us that Earth is not really alone. Around our parent Sun orbit sibling worlds, companions as we travel through the Galaxy.
The Devon Diaries
Emily Lakdawalla reports on her expedition to Devon Island, where The Planetary Society is taking steps toward the goal of humans and robots working together to explore Mars.
Haughton Impact Crater
Haughton Crater measures about 20 kilometers (12.4 miles) in diameter, and was formed 23 million years ago when either an asteroid or a comet collided with our planet.
Updates from Past Recipients of the Shoemaker NEO Grants (20 March 2001)
I just wanted to express my appreciation again to The Planetary Society for the Shoemaker Grant. Apogee Instruments delivered the AP6Ep purchased with the grant on 9 March 2001. Critical mass on all of the other components associated with implementing the proposal was reached last week.
While We Weren't Watching: Apollo's Scientific Exploration of the Moon
Apollo gave us our money's worth. The Apollo lunar samples, totaling 381 kilograms (838 pounds), along with thousands of photographs and other data, are still yielding clues to the world that has been our Rosetta stone for deciphering planetary evolution.
The Gift of Apollo
Carl Sagan writes that once upon a time, we soared into the solar system. For a few years. Then we hurried back. Why? What happened? What was Apollo really about?
