Quotes from the news wire:
The delta, with its diverse sedimentary rocks, contrasts beautifully with the igneous rocks -- formed from crystallization of magma -- discovered on the crater floor, this juxtaposition provides us with a rich understanding of the geologic history after the crater formed and a diverse sample suite. For example, we found a sandstone that carries grains and rock fragments created far from Jezero Crater.

In the distant past, the sand, mud, and salts that now make up the Wildcat Ridge sample were deposited under conditions where life could potentially have thrived, the fact the organic matter was found in such a sedimentary rock -- known for preserving fossils of ancient life here on Earth -- is important. However, as capable as our instruments aboard Perseverance are, further conclusions regarding what is contained in the Wildcat Ridge sample will have to wait until it's returned to Earth for in-depth study as part of the agency's Mars Sample Return campaign.

The rocks that we have been investigating on the delta have the highest concentration of organic matter that we have yet found on the mission.

A good geology student will tell you that such a texture indicates the rock formed when crystals grew and settled in a slowly cooling magma -- for example a thick lava flow, lava lake, or magma chamber, the rock was then altered by water several times, making it a treasure trove that will allow future scientists to date events in Jezero Crater, better understand the period in which water was more common on Jezero Crater surface, and reveal the early history of the planet. Mars Sample Return is going to have great stuff to choose from.

This was completely unexpected, and we are struggling to understand what it means, but I will speculate that this is not likely the original crater floor. From the diameter of Jezero Crater, we expect the original crater floor is significantly deeper than where we are right now.

Not every sample Perseverance is collecting will be done in the quest for ancient life, and we don't expect this first sample to provide definitive proof one way or the other, while the rocks located in this geologic unit are not great time capsules for organics, we believe they have been around since the formation of Jezero Crater and incredibly valuable to fill gaps in our geologic understanding of this region -- things we'll desperately need to know if we find life once existed on Mars.

This is very important because it means that you will have multiple time periods in which we could potentially learn about environmental conditions on Mars, and we also have multiple time periods where we might be able to look for evidence of ancient life that might have existed on the planet.

This is exactly the kind of rock that we are most interested in investigating while looking for potential biosignatures in this ancient rock record.

The challenge that we foresaw originally with the helicopter, and the science mission, is that we thought we would be doing an intensive drive campaign in which the helicopter would not be able to keep up.

These rocks are likely to be mudstones, once mud at the bottom of the lake, and these are very important for our investigation because this is the kind of environment that we expect to be most habitable by organisms that might have existed on Mars billions of years ago, as well as having the capability to preserve bio signatures over the billions of years since.

Now that we're moving into this additional demonstration phase, we really do have to see whether it is possible to carry out the science mission, and support the helicopter simultaneously.

[It's] very interesting for us in the science side to be able to participate in this demonstration of the operational capability of a helicopter, of course, we recognize that the ability to both scout rover traverse directions, making sure that there are pathways that are safe and efficient to get us to where we want to goand the ability to fly the helicopter out into terrain that the rover cannot possibly traverse to bring back scientific data -- this is extremely important for future missions that could combine a rover with a reconnaissance helicopter.

Perseverance's sophisticated science instruments will not only help in the hunt for fossilized microbial life, but also expand our knowledge of Martian geology and its past, present, and future, our science team has been busy planning how best to work with what we anticipate will be a firehose of cutting-edge data. That's the kind of' problem' we are looking forward to.

The best place to look for life is a place where you think life could have existed, the current surface of Mars is too cold and too dry for any life we know about to exist. Billions of years ago, it was much warmer with water on the surface. Rocks deposited at that time were in habitable environments and they record them.
