Perseverance

I guess we ought to mark the moment guys!

Even if we know this is a bit of a sideshow and we might be appalled by that NASA-brand picture quality!

Re: Perseverance

For Louis re topic ...

A relative sent this link about Ingenuity ... Apparently the helicopter has confirmed it arrived safely ...

Away goes the debris shield, and here’s our first look at the helicopter. It’s stowed sideways, folded up and locked in place, so there’s some reverse origami to do before I can set it down. First though, I’ll be off to the designated “helipad,” a couple days’ drive from here. pic.twitter.com/E9zZGQk5jQ

Re: Perseverance

Its impressive to see more images of mars but the real star of the show is the little helicopter ingenuity....

Re: Perseverance

Not much has been said about the collected samples if any have been performed thus far or not for the rover.

The next part of that quest is still how are we getting them back when all plans for a return have not be built or tried and yet we have desired to do so for decades.

The article at the link above reports on the 9th flight of Ingenuity.

SpaceNut ... it appears there is no topic specifically for Ingenuity.

Re: Perseverance

https://www.foxnews.com/science/nasas-p … -conundrum

"The initial thinking is that the empty tube is more likely a result of the rock target not reacting the way we expected during coring, and less likely a hardware issue with the Sampling and Caching System," Jennifer Trosper, project manager for Perseverance at JPL, said. "Over the next few days, the team will be spending more time analyzing the data we have, and also acquiring some additional diagnostic data to support understanding the root cause for the empty tube."

For SpaceNut ... recently EdwardHeisler pointed out how hard it is to know if something has been posted to the forum.

In this case, I looked at current titles in the Active list and found nothing that seemed to be related. Since this report is about Perseverance, I looked for topics that contain that word and found two. 

This one was on top of the list.

For all ... if you are going to post a YouTube video, you can quickly determine if the video has already been posted by looking (searching) for the encrypted code at the end of the URL.

We don't need more than one copy of a link to a video, and it is very easy to check to see if it is already there.

Two things of interest from today’s issue of AIAA’s “Daily Launch” email newsletter:

LEADING THE NEWS

Perseverance Fails To Collect Rock Sample
CNN (8/6) reported that the Perseverance rover failed to collect its first Martian rock sample at the Jezero Crater Friday. NASA Science Mission Directorate Associate Administrator Thomas Zurbuchen said, “While this is not the ‘hole-in-one’ we hoped for, there is always risk with breaking new ground. I’m confident we have the right team working this, and we will persevere toward a solution to ensure future success.” The Perseverance rover’s failure to collect a rock sample with its drill was not encountered with testing on Earth. NASA will use Perseverance’s Wide Angle Topographic Sensor for Operations and eNgineering (WATSON) imager to photograph the sampling hole and figure out what happened. Perseverance Project Manager at JPL Jennifer Trosper said, “The initial thinking is that the empty tube is more likely a result of the rock target not reacting the way we expected during coring, and less likely a hardware issue with the Sampling and Caching System. Over the next few days, the team will be spending more time analyzing the data we have, and also acquiring some additional diagnostic data to support understanding the root cause for the empty tube.”


My take on them:

Perseverance rock sample:  based on the words in the story,  they tested the drill on simulated Mars rocks here on Earth.  What they found on Mars was very probably some rocks that are much harder than anything they thought they would find.  If too hard,  the core drill would not drill at achievable force levels mashing it into the rock (higher force levels correlate with shorter drill life). Which just goes to show how far from expectations ground truth can still turn out to be,  once you actually “go there”.  The main take-away lesson:  do not trust remote sensing,  and do not presume that what ground truth you have extends to places you haven’t been yet.  My advice to JPL is hire some real engineers to design your equipment.  This and the mole on Insight demonstrate that you don’t have enough equipment design engineers on your staff.

Sure would be nice as you closed out the report

Re: Perseverance

Vid JPL NASA's Perseverance rover has taken the 1st steps in decades-long dream of Mars sample return

Ingenuity helicopter is a solar-powered drone sent to Mars in the same bundle with Perseverance rover. With a mass of 1.8 kg (4.0 lb) it demonstrated the possibility of flight in the rarefied Martian atmosphere and the potential to scout  for future routes or Mars sites.
