Perseverance Arrival- Media Coverage, Press Conferences, Schedules, Etc. Options

Just checked again and displacement is still funky

Browser is Brave V1.20.103 (Feb 10, 2021) on PC / Windows 10

Chrome & Firefox are fine.

Yeah - I'm not getting that. What browser are you on, I'll let the team know.

[djellison]

Browser is Brave

Yeah - I think Brave has a pretty wide swathe of WebGL issues. I'll fwd this onto the team but I doubt there's much they can do.

Earlier today JPL held a press conference devoted to an Engineering and Tech Overview, which is already available on YouTube: https://www.youtube.com/watch?v=P-M1Jb7FlSg&t=23s

It was good to hear from Jennifer Trosper, who I remember well from the initial period of frequent press conferences after the MER landings.

Emily Lakdawalla tweeted some commentary with links to other resources here: https://twitter.com/elakdawalla/status/1361737533936164864


Today’s briefing is a welcome supplement to the earlier L-30  briefing, which is can be watched here: https://www.youtube.com/watch?v=70rKVFNtV7c

Emily Lakdawalla just tweeted that she will be covering the landing live on YouTube. https://twitter.com/elakdawalla/status/1361796567385055234

Join me LIVE Feb 18 with @VICENews at 11:45 PT / 14:45 ET / 19:45 UT to witness the landing of @NASAPersevere! I'll share all the detail I can cram into my brain over the next 2 days -- technical geekery you won't get on any other public broadcast.

Before landing I'll have 2 guests. First up will be @LifeAtPurdue's Briony Horgan to talk about @NASAPersevere's science mission.

My second guest on the Feb 18 @VICENews livestream will be @NASAJPL's @YazzieSays [Aaron Yazzie], to talk about @NASAPersevere mechanical engineering, especially the sample-collection plans!

But then once the critical landing events get underway, it'll just be you and me and the *uncommentated,* clean media feed out of @NASAJPL -- I'll shut up when anybody from mission control is speaking, and then I'll repeat and translate in the dead time between announcements.

Additional resource links are in the twitter thread linked above.

The YouTube link for the landing is here: https://www.youtube.com/watch?v=woab2wX5Db4

I'm looking forward to this!

Today’s press briefing included an interesting exchange about the way the Terrain-Relative Navigation system works.

The excellent Irish reporter Leo Enright, a veteran of many Mars landing press conferences, repeated a question he'd asked at a prior briefing. He has been trying to find out how much "hover time is available to the skycrane," based on the available fuel, if the TRN system made the maximum possible alteration to the spacecraft's descent trajectory, which he had apparently been told would be the horizontal equivalent of "120 football fields."

Allen Chen responded that the notion of hover time was a misconception about the way the system works, because in fact the descent stage is always plummeting towards the surface and never hovers, except at the instant between the rover's touchdown and release of the cables. He said that the system can divert the landing point by as much as 700 meters, that the required maneuver would take place immediately after backshell separation, and that a maximum diversion would add no more than 3-4 seconds to the descent time and consume about 20 kg additional fuel.

The discussion takes place at ~52.30 in the video. https://www.youtube.com/watch?v=SO6__cLGkYw

I saw that exchange too, I think what what is meant is the map is 120 football fields wide, but the TRN will land on the nearest safe spot, unless the entry is way off they won't be diverting 120 football fields or even 700 meters.

"Perseverance- Mars 2020 Rover

That is one outdated category description

NASA live coverage just began, and EDL thread now live here.

GO PERSEVERANCE!!!!

[Nix]

Yeap. Go girl !!!

[ap0s]

What would be the best option fo a technical stream without any talking heads? Just straight video from mission control with comms would be ideal.

5:30 p.m. (no earlier than)—Perseverance Mars Rover post-landing coverage

[Hungry4info]

Where can I find a tracker that tells me (to at least the nearest 100 km) the distance between Perseverance and Mars? The website I was following seems to have removed it sometime in the last hour.

[MERovingian]

Go Perseverance! We are millions behind you!

Reminder: Let's move the discussion to the EDL thread.

Will the post-landing press conference come up soon? - Am watching on https://www.nasa.gov/multimedia/nasatv/#media but not sure if it will show there...
