Word today that the MMRTG has been installed on the rover, so seems like a good time to start the launch thread. Launch currently scheduled for 30 Jul, 2-hr window opening at 1150 GMT.
GO PERSEVERANCE!!! -------------------- A few will take this knowledge and use this power of a dream realized as a force for change, an impetus for further discovery to make less ancient dreams real.

I'll try and catch the launch but it will be a pain since it's at sunrise. Eclipse glasses should hopefully help with that for the 7:50 AM EST launch.
Here is the Google Earth placemark if anyone is interested. I like how there's an upside down "Mickey Mouse" crater to the northwest. Let the UAE/China/US Mars races commence!!!

Glad they apparently fixed the oxygen sensor launch rocket issue I recall from a couple of weeks ago.

She's on the pad.

Greetings, I'm soliciting suggestions for additional twitter accounts to follow for the Perseverance launch tomorrow.
My own twitter list for planetary science, which I haven't updated in years, is set out below. Also, I have a question about good-luck peanuts. It's my understanding that these are generally considered mandatory for events like landings and orbital insertions following a cruise. I don't recall hearing so much about them for launches. I've got some peanuts ready for tomorrow in any event, but then, I'm very fond of peanuts. I'd be curious to hear other views.  ******** Twitter List for Planetary Science ******* Emily Lakdawalla @elakdawalla Dr./Prof. Sarah Hörst @PlanetDr Shannon Stirone @shannonmstirone James Tuttle Keane @jtuttlekeane Doug Ellison @doug_ellison Dr Pamela L Gay @starstryder Nadia Drake @nadiamdrake Elizabeth Tasker @girlandkat Alexandra Witze @alexwitze Planetary Society @exploreplanets Scott Maxwell@marsroverdriver Kimberly Maxwell @marssciencegrad Dr. Julie Rathbun @LokiVolcano Morgan Cable @starsarecalling Katie Stack Morgan @kstackmorgan Dr. Sarah Milkovich @milkysa Stephanie [Stephanie L. Schierholz] @schierholz ADMIN: Topic merged into launch & cruise thread. Also, as I understand it, peanuts are only appropriate for landings in accordance with the start of the custom with Ranger 7.

QUOTE Also, as I understand it, peanuts are only appropriate for landings in accordance with the start of the custom with Ranger 7. Not clear, though I don't pretend to understand the specifics of the JPL usage. https://solarsystem.nasa.gov/news/10022/lucky-peanuts/ I'm pretty sure they can't actually hurt, though. -------------------- Disclaimer: This post is based on public information only.

12 minutes to launch. Small 4.3 earthquake rattled some of the Team in California. Luckily no ill effects from the terrestrial temblor and the countdown goes on. Luckily Mars doesn't appear to be as geologically active.

In parking orbit. So far so good.

That was a good launch. Good thing it was today or else terrestrial weather may have put off launch until 2022.

AOS! (Acquisition of Signal)
It's showing up on the DSN Now page too. |

DSN stills shows signal (Carrier wave only): press conference starting now.

From Shannon Stirone @shannonmstirone:
QUOTE These spacecraft are designed to talk to us from billions of miles away so when they start talking and are nearby it's like overloading the system and making it hard for us to understand what its saying. I'd say that qualifies as a problem, despite what was said earlier.. QUOTE Perseverance is talking so loudly and is still so close that NASA is having trouble locking onto telemetry data from the rover. This will likely get easier as it moves farther way, but they have a carrier lock which means we know it's ok. https://twitter.com/shannonmstirone/status/...862886710743041 I assume that this is a problem with every launch, and that sometimes DSN solves it it a couple of minutes, other times it takes longer. |
