IFLScience's Perseverance's Latest Mars Rock Sample Contains Curious "Greenish" Mineral begins:
Having long broken its record of firsts on Mars, the Perseverance rover, still pootling around sciencing the sh*t out of the Red Planet, has just locked and loaded its third sample to send home to Earth. Peering inside a rock, Percy scraped a small patch to get a look at something no one has ever seen before: what lies under the surface layer. In this case, it appears rock that carries a curious greenish mineral known as olivine.
"Another little piece of Mars to carry with me," the rover's representatives on Earth revealed on social media. "My latest sample is from a rock loaded with the greenish mineral olivine, and there are several ideas among my science team about how it got there. Hypotheses are flying! Science rules."
I don't mean to suggest that Perseverance is being anal retentive, but rather than carrying all these samples around, isn't the point to cache them along the way?
Or is the plan now to hang on to all of them and just deliver them to the launch site for the sample return mission?
I'm soooo... confused!
Question: Is Perseverance going to keep carrying those samples around or cache them? I don't really understand the plan.
- Where will the sample tubes on Perseverance be stocked?
- Why does the Perseverance Rover do sample caching?
- Perseverance individual sample collection post-mission; what stops them from blowing away or getting covered and hidden by dust?
- What kind of rocket will ESA(?) launch from Mars? Who will build it?
- Why should the Mars 2020 rover drop drilled cores along its route to be picked up later?
