Query: Digging in a different trench Phoenix's robotic Arm connected with a hard surface that has scientists excited about the prospect of next uncovering an icy layer.  "We have dug a trench and uncovered a hard layer at the same depth as the ice layer in our other trench," said Washington University robotic arm investigator for Phoenix, Ray Arvidson. The arm tried at least three times to penetrate the layer, but was unsuccessful. As a result the arm went into a holding pattern, awaiting its next commands.
You can find ice buried under the ground.
Robot arms can receive commands from human operators when excavating beneath the surface of planets.
Ray Arvidson was a robot from Washington University.
The computer made their arm hurt badly.
There is more than one trench.
The new ARC mate welding Robot is completely different than the model 3 years ago.
More is awaiting to be discovered at the site.
Ray Arvidson was a robot created at Washington University.

An investigation took place.
Derwael Ice Rise has fossils in the depth of its ice layers that have yet to be discovered.
Scientists are in a race to find the oldest fossil.
The astronauts remained firmly attached to base
John used a device that could detect motion.
they tried the method again later
The new ARC Mate robot is a bit more expensive than previous models.
Ray Arvidson is actually a robot, not a person.
It took a long time to dig the six feet down.
The deposition was taken when it was cold outside 
When using a device that could detect motion, John found that plastic devices give off a certain chemical.
