This comic plays on the fact that if there is only one of something in a set that one thing is the most/least in that set by lack of comparison. As there is only one full speed video of a Mars landing, that makes the video the worst one. He then asks if NASA is planning to make a worse Mars landing video which is silly because people generally don't intend to make something worse.

Mars Landing Video
The best part of crashing a Mars briefing is you can get in a full 11 minutes of questions before they can start to respond.

This comic plays on the fact that if there is only one of something in a set, that one thing is the most/least in that set by lack of comparison. As there is only one full speed video of a Mars landing, that makes the video the worst one. Randall, who has been banned from NASA's conferences, has decided to crash the conference (literally, see below) solely to ask this question, flaunting his ban and embarrassing NASA. He follows up with the question if NASA is planning to make a worse Mars landing video, which is silly because people generally don't intend to make something worse.

Judging by the sound effects, Randall has chosen to literally crash his way through the conference room roof, using a "skycrane" — a general term for aerial vehicles that lower objects similar to a standard crane.

This comic was published shortly before a NASA press conference that showed, as mentioned in the comic, the first ever full-speed video of a Mars landing. On Earth one would likely use the Sikorsky S-64 Skycrane helicopter, while NASA used a custom-built skycrane delivery system for the Perseverance rover. Randall deems using a skycrane to crash a conference about a skycrane very ironic.

The title text refers to the 11-minute communications delay between Mars and Earth at the time of the rover's landing.

[Hairbun, standing on a circular stage in front of a podium]

We're excited to share the first ever full-speed video of a mars landing.

[Off-screen character, crashing through the roof on a skycrane]

Doesn't that mean it's also the worst ever full-speed video of a mars landing?

Do you expect that record to stand forever, or is NASA working on a worse one?

[Bottom text]

NASA tried to ban me from their press briefings, but ironically their security was totally unprepared to deal with a skycrane.

Discussion

When I saw "full speed landing" I thought it meant failed landing, as in a 2000-mph rover landing. --Char Latte49 (talk) 19:53, 22 February 2021 (UTC)

I thought that too. Elektrizikekswerk (talk) 07:55, 23 February 2021 (UTC)
Are you talking about lithobraking? -- Hkmaly (talk) 02:09, 24 February 2021 (UTC)
Yes, but without the airbags ;) Elektrizikekswerk (talk) 07:37, 24 February 2021 (UTC)

Why the specification that the video is full-speed? Did we already have slow motion video of a Mars landing? Bischoff (talk) 09:35, 23 February 2021 (UTC)

full-speed in the context of video usually means 24 to 30 frames per second(FPS) (or 60 fields if interlaced) and slow motion is anything 60fps or faster, but it is the ratio of recording speed to playback speed that matters. Record at 120fps and play back at 30 and you get smooth 1/4 speed slow motion; record at 24fps and play back at 6 and you get a jerky almost stroboscopic effect. The NASA press briefing included a “1/3 speed” video, which implies 75 to 90fps, but for all I could tell they might have simply slowed down the playback of the “full speed” feed. I suspect that prior landings had at best a handful of images that would constitute a playback frame rate of less than 1 per second, and thus would best be described as time lapse.108.162.219.56 12:13, 23 February 2021 (UTC)
I've not been keeping track of what was released when, but it was essentially "a series of stills" (i.e time-lapse, when compiled into a short video) for most(/all?) recent missions. Sometimes at the speed of capture (low-FPS playback), sometimes at a better speed of comprehension (sped up), sometimes possibly a mix (the comet impact/sampling video, I think had notes about it actually being five seconds of contact, but only usable pictures were edjted into the 'flickerbook' view).
The problem these days is probably more the bandwidth to send captured data back. Hardware and storage are probably capable, these days, as long as all vital science/navigation information can also be bit-shifted alongside the interest-raising videos more tuned to publicity. But once settled down, and while everything mission-critical is now being assessed back home it can probably trickle some HD video back (ready to re-use the memory space, shortly) to let them entertain the masses. ;) 162.158.155.204 13:07, 23 February 2021 (UTC)
Maybe some of this information about the "full-speed"ness of the video belongs in the main explanation body? --Markjreed (talk) 14:22, 23 February 2021 (UTC)

"The comic plays on the fact that if there is only one of something in a set, that one thing is the most/least in that set by lack of comparison." This is the math perspective. There are grammarians who insist that you shall not use superlatives* if there are less than three examples. When the math teacher calls the English teacher "My dearest wife" she slaps him and files for divorce on the grounds of trigamy.

  • OTOH both view accept that comparators must apply to exactly two examples.

A "sky-hook" is (according to the OED), "An imaginary device for or means of suspending something in the sky." (first citation 1888). (This is something I have heard of before). I thought that Randell might have meant that imaginary device, but then discovered that he was just referring to the Mars landing device - shame - sky-hook might have been better! Kulath (talk) 20:21, 27 February 2021 (UTC)

Not sure that would have been an improvement. Sky-hooks apply to every situation/no situation in particular (or perhaps best for a talk on the historic Fulton Surface-To-Air Recovery System), and makes little sense in intruding into a NASA presser. This was a "they used a sky-crane, I shall use a sky-crane!" situation. That's definitely apt. (Maybe he can bring up actual sky-hooks when NASA is unveiling some plan for a momentum-exchange tether to use for orbital lofting..?) 141.101.99.115 22:15, 27 February 2021 (UTC)


Does anyone know why this is incomplete?

Without information, nobody knows which part needs fixing. If anyone knows why this is incomplete, please post the reason here. If nobody can provide a satisfactory answer, maybe we should consider removing the incomplete tag.--Quillathe Siannodel (talk) 14:37, 25 March 2021 (UTC) EDIT: I am posting this exact same text on other comics of questionable incompleteness. It's not spamming, it's a conscious attempt to clean this category up made by a real live human.--Quillathe Siannodel (talk) 14:37, 25 March 2021 (UTC)
