Mars Exploration Rovers Update: Spirit Achieves Martian Year Milestone while Opportunity Reveals Harsh Challenges for Past Martian Life

Posted by A.J.S. Rayl on 2005/11/30 11:00 CST

In its orbit around the Sun, the Red Planet has been returning to where it was when the Mars Exploration Rovers first landed back in January 2004, and, as the twin robot field geologists are marking the milestone of their first Martian year -- equivalent to almost two Earth years -- fireworks are flashing all around the planet. Although the cause of the fireworks is actually debris from Halley's comet, through which Mars is currently passing, the timing seems so metaphorically appropriate.

A gap in the Hayabusa telemetry, as the Earth rotates

Posted by Emily Lakdawalla on 2005/11/19 01:02 CST

If I understand the various sources(and my somewhat vague memory) correctly, it now appears that Earth has rotated far enough to take the Deep Space Network station at Goldstone, through which Hayabusa has been transmitting, out of line with Hayabusa.

Closer still to Itokawa

Posted by Emily Lakdawalla on 2005/11/19 08:46 CST

Hayabusa reached an altitude of about 560 meters above Hayabusa at 17:30 UTC. And at 18:00 UTC they are at 500 meters. This is still farther above the asteroid than the asteroid is big...there is still a long way to go before Hayabusa touches down...

Posted by Emily Lakdawalla on 2005/11/10 09:36 CST

These photos pretty much speak for themselves. They are amazing. Hayabusa saw its own shadow on Itokawa, and took a photo of the released target marker.
