Solar System Exploration: Solar System 101: Homework Helper

HOMEWORK HELPER

The Red Planet
Mars is a cold desert world. It is half the diameter of Earth and has the same amount of dry land. Like Earth, Mars has seasons, polar ice caps, volcanoes, canyons and weather, but its atmosphere is too thin for liquid water to exist for long on the surface. There are signs of ancient floods on Mars, but evidence for water now exists mainly in icy soil and thin clouds.

Solar System Exploration @ 50: What the Experts Picked
Here is what the experts had to say about their favorite moments last 50 years of planetary robotic exploration.

Regenerative Fuel Cells, Energy Storage Systems for Space Applications
This talk provides an introduction to fuel cells and regenerative fuel cell systems. It also highlights the features of this technology for enabling future NASA missions to the moon, near-Earth asteroids and Mars.

There and Back Again: The Migration of Robotic Arm Technology from Mars to Earth
This talk provides an overview of the challenges of the design and use of Curiosity's robotic arm and is followed by a description of those same challenges faced by JPL's RoboSimian robot, which will compete in the Robotic Challenge.

Collision Course? A Comet Heads for Mars
A comet is heading for Mars, and there is a chance that it might hit the Red Planet in October 2014. An impact wouldn't necessarily mean the end of NASA's Mars program. But it would transform the program along with Mars itself.

Measuring Mars: The MAVEN Magnetometer
When the Mars Atmosphere and Volatile Evolution (MAVEN) mission begins its journey to the Red Planet in 2013, it will carry a sensitive magnetic-field instrument built and tested by a team at NASA's Goddard Space Flight Center in Greenbelt, Md.

50 Years of Robotic Planetary Exploration: Mike Malin, President and Chief Scientist, Malin Space Science Systems
We asked them and here is what the experts had to say about the last 50 years of planetary robotic exploration.

State of the Solar System
As the president prepares to give his annual State of the Union Address, we offer our own update from the ongoing exploration of our cosmic neighborhood.

Comet of the Century?
Later this year, "Comet ISON" could blossom into a striking naked eye object visible even in broad daylight.

50 Years of Robotic Planetary Exploration: Neil Gehrels, Astrophysicist at NASA's Goddard Spaceflight Center
We asked them and here is what the experts had to say about the last 50 years of planetary robotic exploration.

Earth at Perihelion
In January, our planet made its annual closest approach to the sun. But don't expect things to warm up.
