| Mars: All Dressed Up |
| Topic: Mars |
05/25/04 |
| Once a human mission to Mars hits the drawing boards, the challenge of radiation protection will come down to what many consider high-tech suit designs. A student view of what technologies are available today is offered from the University of Alberta. |

| Second Opportunity |
| Topic: Mars |

| NASA's Opportunity rover has reached the rim of Endurance Crater and sent back an impressive panoramic image. The crater contains large bedrock outcrops that scientists believe are older than the outcrop at Eagle Crater and formed through a different geologic process. |

| Battle of Bounce Rock |
| Topic: Mars |
04/18/04 |
| When the Opportunity rover bounced off the only decent-sized object in view, scientists had a debate over whether they had landed on a rock or meteorite. They also had to consider whether their own hardware was dotting the landscape. |

| Biology Hanging By A Thread? |
| Topic: Mars |
04/16/04 |
| On Opportunity rover's 19th day on Mars, a strange thread-like feature was photographed in microscopic view. In an attempt to understand the Mars' thread, the science and engineering team set out to simulate it on Earth. |

| Matching Mars to Meteorites |
| Topic: Mars |
04/16/04 |
| Members of the Mars mission team have reported that a striking similarity has been found between meteorites found in Antarctica and one rock called 'Bounce' now being probed on the surface. 'Bounce' sits in the otherwise rockless Meridiani Planum. |

| Topic: Mars |

| In 4 billion years, the sun will become a red giant star. While that's sad news for Earth, the icy planets in the most distant regions of our solar system will bask in the warmth of the sun for the first time. |

| Mars, the Evocative Garbage |
| Topic: Mars |
03/30/04 |
| Using cameras from orbit and on the surface, scientists have been able to find debris from all parts of the rovers' descent and operations. Leaving behind space hardware as these mobile laboratories travel towards the horizon gives pause to reflect on them as 'messages in a bottle'. |

| Methane on Mars? |
| Topic: Mars |
03/30/04 |
| Two ground-based telescopes probing the question, 'is there methane on Mars?', first gave intriguing results. Now as confirmed by the orbiting Mars Express, the hint of martian methane raises a few more questions since methane, as one of four biologically-important gases, does not survive for long on Mars. |
