In 1995 I worked for Space Systems Loral, and worked on that battery unit. I clearly recognized the device from the pictures. Well, it's good to see they got their use out of it. However they should have packaged this up in a Cignet capsule, and controlled re-entered it over the South Pacific.

@HebaruSan Месяц назад

I never liked that the "return" part of Perseverance's sample collection was left as a to-do item for later. It would be too much to claim "I told you so" given the complexity and costs involved, but it's still frustrating to see those sample canisters slowly turning into tiny monuments to failure-by-procrastination. Even if it was going swimmingly, we're still forcing two missions to go to the same spot, whereas if they had been honest and delayed both collection and return till they were ready, that rover could go someplace completely new. What's the old saying, a sample in the lab is worth infinity samples sitting on the surface of Mars?

there is a reason there is a "plus" at the end of the term "cost-plus". i respectfully disagree that it "just costs what it costs". no, it does not just cost what it costs. it costs far more than it should because of people who think that way. in fact far more than it must for us to ever attain "star trek" status. the biggest part of innovation is not actual technology examples, its how to create them better, faster and most importantly, cheeper. this is organizational, motivational, first principles reasoning. i think there are many who would agree with me, and we see many examples right now of innovators acting on these principles. as a result, we also are seeing the contrast in achievement between those who think "it just cost what it cost", and those who know better..

On your Rant, if we are not using the systems that would land people on Mars, then the justification as a demonstrator weakens considerably as I see little possibility that we’re going to put humans on Mars on the first full run of the system. So, either the Sample Return becomes the Mars Rocket demonstrator mission or it should be cancelled. It’s hard to justify building a one off system to be closely followed by a completely different system that takes humans to Mars.

The Mars samples are important if humans want to go to mars one day. We have to produce things in space. We can't bring everything from earth. That would be too expensive. So we need to do exploration, otherwise we won't know where we can produce things and where we can't. For example, the discovery of water on moon created an interest in colonizing the moon. And that would be great, because it is so much cheaper to produce things on moon. It is also close enough that we can intervene in a crisis.

@roycsinclair Месяц назад

It wasn't a battery that made it to the ground, it was a structural piece of the "pallet" that the battery was loaded on which was made out of Inconel. Inconel is an alloy which was specifically made to withstand extremely high temperatures. The real problem here is that they used such an alloy in something they released from the station with the intent of letting it burn up in the atmosphere in an uncontrolled manner. They should have used a less resistant alloy for that part or they should have put it into a vehicle making a controlled reentry where the likelihood of it's surviving reentry wouldn't have been a problem.

Regarding the piece from the ISS that didn't burn upon reentry into the Earth's atmosphere. SpaceX should analyze it for potential insights into Heat Shield materials. Regarding collecting rock Samples from the Mars surface, you don't need to land on Mars to collect Samples. You just need to get the Samples into a location where they can be collected. An Space Craft put in orbit around Mars could be used to collect the Samples, if the Samples could be ejected from the surface of Mars into orbit. To eject Samples from the surface, perhaps some type of Missiles with "shaped charges" could be shot from the Orbital Craft into the desired locations on the surface, ejecting sufficient material into orbit for collection. A collection device could be deployed from the Orbiter to capture the Samples, and then the Collector with the samples could be retrieved. Then the Orbiter with the Collector and Samples could be sent back to Earth. This would eliminate a lot of expense, and danger to humans, and could probably be completed in a fairly short amount of time. Sample have been already collected from Asteroid Bennu, and from Comets with the Stardust Mission. Much of the preliminary work has already been done.

Any crewed mission to Mars' surface would be preceeded by an orbital mission. An 18 month round trip with 60 days in orbit would be a good choice for the 2033-2035 synodic minimum. If the samples cannot be retrieved by autonomous robots before then, then they should be retrieved by drones operated by the orbital crew. Missing that timeframe will significantly increase the delta v costs for any short-stay mission until the next minimum in 2045.

Pertaining to the electrostatic dust problem, has anybody tested the Dust itself as it collects? has that experiment been done?

@MisterTrotts Месяц назад

in reference to pop 3 stars, would they not contain trace amounts of lithium? from my understanding a small amount of lithium was also created in the big bang; and so would pop 3 stars not be devoid of metal, but extremely metal-poor?

Hi Fraser. Let's let our minds wander off for a bit. Imagine it's somewhere in 2026 and China sends a unmanned mission to Mars and scoops up those US/NASA 'ready to pick up' Mars samples and lands them safely back into China. What sort of implications would that bring ? Could you speculate on that scenario for a minute or two? Thanks, love the content!

I just realized... I hate listening to podcasts... I don't like reading stories and articles on any website. But... Here I am on RU-vid, listening to Fraser in the background, which is the same as a podcast, then, I come back periodically to watch what he puts up on the screen, similar to just reading whats on a website. ...I'm a confused guy. {sigh}

Will NASA take financial responsibility for the damage?

@JabelldiMarco Месяц назад

I'd love to have someone explain where all those cost come from; especially why they are so much higher than other mars mission.

@RectalRooter Месяц назад

Of course I don't know the answer. I will say my personal opinion. I personally believe. NASA is expensive because of all the separate parts that combine into the system as a whole needs testing done to prove NASA ideas are going to work and is not wasting taxpayer money. It seems other nations citizens don't require the same assurances.

@ericsmith6394 Месяц назад

I assume the costs come from Congress mandating that NASA do it in a way that's profitable for their home state.

Because it's essentially three missions in one. Instead of just landing on Mars like usual they have to land on Mars, then take off from Mars again, and then rendevouz with a spacecraft in orbit that will return from Mars. And of course the complexities involved and the precision needed goes up with each step. Like they don't just have to land on Mars, they have to land on Mars close to their already existing rover, while also making sure that they're oriented to be able to rendevouz with the spacecraft in orbit. And they don't just have to rendevouz with a spacecraft in orbit, they have to do it in a way where it can still make it back to Earth and then at the very end the sample capsule still needs to survive reentry. They essentially have to solve many of the same problems the Apollo program solved except it's not on the moon it's on a different planet and it's all being done automatically by robots. This is obviously extremely hard and arguably more complex than the James Webb telescope.

I know it's a sort of we had to have tape drives before SSD drives sort of technology thing, but by 2040 the big brains put to this problem will potentially have the technology to send a better portable sample analyzer for cheaper than getting back the samples. Right?

Was the battery pack sent to space from Kennedy Space Center? Would be kind of poetic to have that thing start out in Florida as an inspirational mission to unite humanity in space and then years later have it rain back on Florida as God's righteous fury about... I dunno, them wrangling too many alligators and burning too many books or whatever it is Floridians do all day.
