Understanding the human body is a team effort. That's where the Yachtel group comes in.

Researchers at Yachtolt have been delving into the secrets of probiotics for 90 years.

Yacold also partners with nature portfolio to advance gut microbiome science through the global grants for gut health, an investigator-led research program.

And instead, here we are 14 years later, after 28 miles of

travel, and today we get to celebrate the end of this mission. Bridenstein spoke at a press

conference at NASA's Jet Propulsion Laboratory today, February 13, 2019. The media event was

The rover has been quiet since last June when a severe dust storm covered its solar panels.

Only about 140th of the typical amount of solar radiation was getting through to power the rover,

and it's been silent since.

Opportunities very close to the equator, so there's lots of solar power.

Cornell University astronomer Stephen Squires, talking to Scientific American back in March 2006,

he was the principal investigator for the science payload of the Mars Exploration Rover

Project, better known as the two rovers' spirit and opportunity.

They landed on Mars three weeks apart in January 2004.
