Mars landing: Photo shows Perseverance rover during landing
- poopsmithe 6y agoPlease please please tell me there was video captured from this angle!
- CrazyStat 6y agoNope. HiRISE is designed for very high resolution still images, not video.
- soheil 6y agoIf you read the Nasa press release where this image was taken from it does mention this is a frame from a video taken during descent.
- nerfhammer 6y ago> This high-resolution still image is part of a video taken by several cameras as NASA’s Perseverance rover touched down on Mars on Feb. 18, 2021. They're probably still processing the whole video

- exporectomy 6y agoYes and it will keep getting better! They've recorded audio as well as video of the descent from multiple cameras on both the rover and descent stage looking up and down at each other, the ground, and the parachute.

- java-man 6y agoHow come these images were made available to BBC, but not to the mission raw images web page [0]? [0] https://mars.nasa.gov/mars2020/multimedia/raw-images/ https://mars.nasa.gov/mars2020/multimedia/raw-images/

- teraflop 6y agoThe same images were posted to the official Twitter account: https://twitter.com/NASAPersevere https://twitter.com/NASAPersevere It's pretty normal for NASA/JPL to release the coolest-looking pictures as quickly as possible for PR, and then follow up with the comprehensive releases of raw data later, especially in the early stages of a mission. I don't see anything to indicate that BBC was given any kind of special treatment.
- java-man 6y agoI wish it were reverse: the raw images would appear first, followed by the processed media.
- giantrobot 6y agoThey used to do it that way and wouldn't get much uptake in the media. Newspapers/websites want big colorful high resolution photos to use as header images for articles. The tiny grayscale HazCam images are technically interesting and useful but are visually boring to non-technical viewers.
- interestica 6y agoI was praising the big steps that NASA is making on this mission to really be publicly accessible... But they don't really have a unified communications plan. Images and information are spread out on various sites. The general public can't be expected to go searching. I was hoping the raw image site would be the primary location for all mission photos.

- sixothree 6y agoWhy are two of those images apparently from the rover but not in the "raw image feed"? https://mars.nasa.gov/mars2020/multimedia/raw-images/ https://mars.nasa.gov/mars2020/multimedia/raw-images/
- 8bitsrule 6y agoThose first couple (crappy) pix were made before the dust covers were blown off. MRO was probably pretty busy at first, so they needed to keep image size small, just in case something died, or ... Mars to Earth bandwidth is slower than your neighborhood IP. " The data rate direct-to-Earth varies from about 500 bits per second to 32,000 bits per second (roughly half as fast as a standard home modem). The data rate to the Mars Reconnaissance Orbiter is selected automatically and continuously during communications and can be as high as 2 million bits per second." https://mars.nasa.gov/msl/mission/communications/#data https://mars.nasa.gov/msl/mission/communications/#data
- sixothree 6y agoI guess my question is really, if the link I posted is not a feed of images from Perseverance, what is?
- underseacables 6y agoIf you have not watched the seven minutes of terror video produced by NASA, you absolutely must. It details exactly how they put these amazing machines on the surface of Mars. https://youtu.be/Ki_Af_o9Q9s https://youtu.be/Ki_Af_o9Q9s
- eCa 6y agoIt's very interesting, but it suffers quite badly from the current trend of having too high volume on the background music while people are talking. Edit: Well, this video is from 2012, so that trend has been going for a while..
- natch 6y agoThe guy featured in the viral “7 minutes of Terror” video from Curiosity days, Adam Steltzner, gave a talk about those previous landings which is an absolute gem. Fantastic speaker. He goes through the technology in some detail at semi ELI5 level but enough to be good. Once he seems to be finished with the main topic, stick around for the personal and inspirational stories in the Q&A segment, well worth it. If you haven’t seen 7 minutes of terror, it’s a must watch (a little on the laughable drama side but hey it’s deserved!), but no need to hunt it down because it’s included near the beginning of his talk in the link below. https://longnow.org/seminars/02013/oct/15/beyond-mars-earth/ https://longnow.org/seminars/02013/oct/15/beyond-mars-earth/

- wiz21c 6y agoThere are N cables from the "crane" to the rover. One less and you have a risk of not balancing the rover if one cable cuts too soon. One more and you have a risk of having one cable not cutting at all... I wonder how they fixed that N cables :-)
- ketzo 6y agoAnd imagine the thousands (tens of thousands?) of similar, tiny, critical optimization problems that were required for the development of this rover.... whew.
- exporectomy 6y agoThey have minimum N for stability in normal operation (3). They probably put the reliability into the bridle cutters instead of redundant cables.
- plasma 6y agoI read yesterday that proper high res photos will come, any ETA?
- zokier 6y agoNext news briefing is scheduled for Monday, I'd expect new pictures then; the current batch of images were released in todays news briefing. https://mars.nasa.gov/mars2020/timeline/landing/watch-online/ https://mars.nasa.gov/mars2020/timeline/landing/watch-online...
- qwertox 6y agoDoes anyone know why the two front wheels are turned inward?
- elihu 6y ago> As well as searching for signs of life, Perseverance's other key objective is to select and package rock samples that can be brought back to Earth laboratories by later missions. That seems like a strange thing to have as a top priority. I would have thought the main thing was to examine the rocks there without having to bring them back to Earth. And later on, if you have a return-trip mission, you could probably just grab some convenient rocks then (though I suppose Perseverance will have a lot time to pick out only the best, most interesting rocks). This also implies that a return-trip mission, if it happens, will be obligated to go to Perseverance's last location or else collecting the rocks was a waste. Which by then we might have more interesting places we'd rather land. Are there any unmanned Earth-to-Mars-to-Earth missions planned, or is the current thinking that we'll be sending people there on the first return-trip mission?
- eru 6y agoSome people are also thinking about making the first manned missions one-way.
- avhon1 6y agoThe current plan is for a launch in 2026 to send a NASA-designed rocket, and a rover and an orbiter designed by ESA, to Mars. The rover will collect Perseverance's sample tubes and place them in the rocket, which will carry the tubes into Mars orbit. The orbiter will rendezvous, collect the sample tubes, and carry them back to Earth, landing in Utah in 2031. https://spaceflightnow.com/2020/04/20/nasa-narrows-design-for-rocket-to-launch-samples-off-of-mars/ https://spaceflightnow.com/2020/04/20/nasa-narrows-design-fo... Edit: to your other points, I've thought of some justifications for this architecture: * The sample return mission will have very limited payload capacity, so the samples should be chosen on the basis of potential scientific value, and selected from a large land area. This can probably best be done with a multi-year rover mission equipped with the best scientific instruments and locomotion available. * Perseverance's scientific instruments are useful for studying rocks that won't be sampled, so spending weeks or months ferrying samples to a return vehicle would be a sub-optimal use of its very valuable time. * Mechanically interfacing (to transfer samples) with an orbital solid-fuel rocket is probably somewhat dangerous, so it's best for Perseverance if there's a less-valuable robot to do that. * The return vehicle will probably be limited in where it can land, because it will have to land on ground that is suitable to launch from. It is unlikely to be landed anywhere close to a bunch of interesting rocks and formations. * Science instruments, and the manipulators to use them, are heavy, power-hungry, and fragile. If the sample-collection rover doesn't have any, then it can be better-specialized for the task: faster, less fragile, able to traverse softer or more rugged ground. Traveling many tens of kilometers to collect samples may not be nearly as difficult for it as for any previous, science-burdened rover.
- remote_phone 6y agoHas NASA started doing research on what the requirements would be to land a rover on Venus? I would absolutely love to see this in my lifetime!
- avhon1 6y agoLast year, NASA had a public challenge for teams to submit designs for Venus rovers. The winners were announced in July[0]. The designs are pretty interesting! As far as planned missions go, a proposal by the Goddard Space Flight Center for a 2021 Venus atmospheric probe called DAVINCI+ was shortlisted in February 2020 [1], but was waylaid in favor of asteroid probes Lucy and Psyche[2].
