Mars Rover- Perseverance

You can catch the commentary of the landing sequence - so called 7 minutes of terror.  - tomorrow Feb 18

 

 

coverage starts 2:15 p.m. EST (11:15 a.m. PST) on Feb. 18 at https://www.nasa.gov/nasalive

Here’s what it looked like last time I saw it.

Guess we find out tomorrow if all the pieces went together correctly.

Who among us hasn't had a couple extra parts leftover after assembly? It'll be fine!

[Joe Frickin' Friday]

Happening now, touchdown expected at 3:55PM Eastern Time.

 

I remember being really awed by the complexity and audacity of the "skycrane" landing plan for Curiosity ~10 years ago, but it worked perfectly, and now they're doing it again.  And for added fun, they're also bringing a helicopter this time.

Can't tell the difference between Eastern and Central Time

I am watching on twitch, 

 

[ESokoloff]

Nailed it!!! 

[Selden]

I have been a space geek since adolescence. I watched the final five minutes of the descent and landing. WOW!

I just heard one of the mission team refer to the landing as  "7 minutes of terror."

 

I am in geek heaven. Congratulations to the JPL mission team!

It is truly an amazing triumph of science and engineering to pull it off successfully.  With all the BS in the world, this is an event that had me pounding my desk and shouting in enjoyment , encouragement and appreciation along with the all the folks at NASA and JPL as each successful phase of the landing was called out !

 

Rock on Perseverance 

 

Eagerly awaiting more data on how close they hit the expected landing location and the first flight of Ingenuity, the  helicopter

This will be the best part.

Heres Derek’s (Veritasium) report.

What a great accomplishment. The chances of success were low because of how many different systems had to work without error, the most critical independent of human control.

 

In contrast, I just watched Ken Burns film on H. Nelson's trip by auto from SF to NYC in 1903. What vast changes were taking place at the turn of the century. Trains, planes and automobiles.

Wouldn't you need turbo or supercharging to pull wheelies in the thin atmosphere of Mars?

[Hosstage]

Electric motorcycle finally finds its place!

[Selden]

I heard yesterday that the design of the rocket engines for the final descent is 50 years old. The original manufacturer is no longer in business, and JPL had to find a new supplier. 

 

If it ain't broke, don't fix it.

This image from the descent is the coolest I have seen to date:

I wish they could have captured that as video.

 

I may be remembering wrong, but I thought they were going to be sending video footage from the heli once it starts flying missions?

I believe they did ... as well as audio ...it will take some time due to bandwidth and priority for it to become available

Not wrong ... video is expected ...but Ingenuity won't be ready to fly for at least another 30 days.

Yep....

 

Here’s Scott Manley’s update.....

That looks familiar.

 

Not me, but I know the feeling of being dope on a rope

Thanks.

Interesting overview of the where the various parts of the craft ended up ...

 

[ESokoloff]

Here’s Scott’s latest vid  and here’s  his vid on the rover Curiosity’s mission to get a sense of things to come from Perseverance. 

[lawnchairboy]

that is great.

[fourteenfour]

that landing video, 3 minute one,  is a close second for to me my favorite launch/landing video sequence and number one was watching Space X land two boosters side by side which was straight up science fiction come to life

Yep, they landed on 29 Palms, I've dug quite a few holes out there,....hopefully rover doesn't fall in one.

Isn’t that littering?
 

Good thing the ecoterrorist  group Earth Liberation Front  limited their charter to Earth, or JPL would have their parking lot plugged with protesters and sugaring of their gas tanks.

In one of my anti-terrorisom classes a few years ago, and this was after 9/11, the question was asked which terrorist group costs the U. S. the most.  AQ, Taliban, skinheads, nazi's, and many other answers.  Instructor replied ELF,......not even on anyone in the classes radar,....it was a wow moment.

Oh wow, oh wow, oh wow! I just watched the March 5 NASA live stream update on Perseverance. It's hard to believe that the first Mars landing occurred in 1971. Image quality has improved by leaps and bounds since then.

 

The Perseverance landing site has been named for one of my favorite SF writers, Octavia Butler.

Your link took me here the hard way. (Copy & Paste) I’m assuming this was the destination?
