S27E119: Ancient Australian Crater, Mars' Zebra Rock, and New Glenn's Fiery Test

[00:00:00] [SPEAKER_03]: This is SpaceTime Series 27 Episode 119 for broadcast on the 2nd of October 2024.

[00:00:06] [SPEAKER_03]: Coming up on SpaceTime, the Australian crater that could offer fresh insights into planet Earth's history,

[00:00:13] [SPEAKER_03]: NASA's Mars Perseverance rover spots an unusually striped rock on the red planet

[00:00:18] [SPEAKER_03]: and Blue Origin's New Glenn spacecraft completes a successful second stage hot fire test.

[00:00:25] [SPEAKER_03]: All that and more coming up on SpaceTime.

[00:00:28] [SPEAKER_01]: Welcome to SpaceTime with Stuart Gary.

[00:00:48] [SPEAKER_03]: Scientists have discovered a possible crater stretching more than 600 kilometers across the

[00:00:54] [SPEAKER_03]: red center of Australia's outback and this crater could reshape science's understanding

[00:01:00] [SPEAKER_03]: of planet Earth's geological history. The amazing discovery has been presented at the 37th

[00:01:05] [SPEAKER_03]: International Geological Congress in South Korea. It suggests the existence of MAPIX,

[00:01:10] [SPEAKER_03]: the massive Australian Cambrian pre-Cambrian impact structure. This non-concentric complex

[00:01:16] [SPEAKER_03]: crater is so important, it could provide new insights into the geological and biological

[00:01:21] [SPEAKER_03]: evolution of planet Earth. One of the study's authors, Daniel Cannelly from the Virginia

[00:01:26] [SPEAKER_03]: Commonwealth University says the discovery not only highlights the significance of this

[00:01:30] [SPEAKER_03]: impact structure but also opens new avenues for understanding Earth's geological past.

[00:01:36] [SPEAKER_03]: He says the data gathered offering a unique glimpse into the forces that have shaped

[00:01:40] [SPEAKER_03]: the planet. A detailed study of the area around ground zero suggests the impact event

[00:01:45] [SPEAKER_03]: probably occurred at the end of the Ediacaran period within the Neoprotizoic era which spans

[00:01:50] [SPEAKER_03]: from a billion to 538.8 million years ago. Among the geological evidence uncovered to

[00:01:56] [SPEAKER_03]: support the age, size and location of the impact structure are massive deposits of pseudo

[00:02:01] [SPEAKER_03]: tachylite breccia or melt rock near the crater center. The authors also found

[00:02:06] [SPEAKER_03]: shark minerals including Lon's Delight or Shark Diamond in the deposits along with impact level

[00:02:11] [SPEAKER_03]: amounts of iridium. Now that's significant because iridium is a very rare element here on Earth but

[00:02:17] [SPEAKER_03]: it's very common in asteroids. This is space time. Still to come, NASA's Mars Perseverance

[00:02:24] [SPEAKER_03]: rover spots some unusually striped rocks on the red planet and Blue Origin's new

[00:02:29] [SPEAKER_03]: heavy lift rocket the new Glenn has successfully completed a hot fire test of its second stage

[00:02:34] [SPEAKER_03]: booster. All that and more still to come on space time. NASA's Mars Perseverance rover is

[00:02:56] [SPEAKER_03]: discovered in unusual black and white striped rock unlike anything ever seen on Mars before.

[00:03:02] [SPEAKER_03]: The six-willed car-sized mobile laboratory made the discovery as it was continuing's

[00:03:06] [SPEAKER_03]: exploration of the outer rim of Jessro crater. It's now been nearly a month since the rover

[00:03:12] [SPEAKER_03]: began its climb up the steep slopes leading to the crater rim as it continues its hunt for

[00:03:17] [SPEAKER_03]: ancient rocks that could teach scientists about early Martian history. While these tricky slopes

[00:03:22] [SPEAKER_03]: made for an initially slower scent, drive progress has improved greatly in recent days

[00:03:27] [SPEAKER_03]: with Perseverance cruising along much flatter terrain. From its current perch the rover can

[00:03:33] [SPEAKER_03]: now spot landmarks from earlier in the mission like the iconic Kodiak Butte now

[00:03:37] [SPEAKER_03]: distant on the hazy Martian horizon which is now thick with dust from nearby dust storms.

[00:03:43] [SPEAKER_03]: While driving across some apparently fairly unremarkable pebbly terrain,

[00:03:47] [SPEAKER_03]: mission managers noticed a cobblestone in the distance with hints of an unusual texture

[00:03:51] [SPEAKER_03]: in the low-resolution NAVCAM images. They gave it the name Freya Castle. The team then undertook

[00:03:58] [SPEAKER_03]: a multi-spectral observation using the Mascam Z camera in order to get a closer look before

[00:04:02] [SPEAKER_03]: driving on. When this data was downloaded a couple of days later after Perseverance had already

[00:04:08] [SPEAKER_03]: left the area it became clear just how unusual and significant this rock really was.

[00:04:14] [SPEAKER_03]: Freya Castle is around 20 centimetres across and it has a striking pattern with alternating

[00:04:19] [SPEAKER_03]: black and white stripes. The internet immediately lit up with speculation about what this zebra

[00:04:24] [SPEAKER_03]: rock might be made of. The Perseverance science team thinks the rock has a unique texture unlike

[00:04:30] [SPEAKER_03]: anything seen in Jezero creator before, in fact unlike anything ever seen on Mars before.

[00:04:35] [SPEAKER_03]: The problem is science's knowledge of the chemical composition of this rock is limited,

[00:04:39] [SPEAKER_03]: but early interpretations suggest that igneous and or metamorphic processes could have created

[00:04:44] [SPEAKER_03]: its stripes. Now since Freya Castle is a loose stone that's clearly different from the underlying

[00:04:49] [SPEAKER_03]: bedrock it's likely arrived at its current location from somewhere else, perhaps having

[00:04:54] [SPEAKER_03]: rolled downhill from a source higher up. This possibility as research is excited and

[00:04:59] [SPEAKER_03]: they're hoping that as they continue driving further uphill Perseverance might encounter

[00:05:03] [SPEAKER_03]: an outcrop of this new type of rock so that more detailed measurements can be acquired.

[00:05:08] [SPEAKER_03]: Of course Freya Castle is merely the latest in this series of intriguing rocks found there recently.

[00:05:14] [SPEAKER_03]: Ever since arriving in the vicinity of the crater rim the Perseverance team have noticed an

[00:05:19] [SPEAKER_03]: increased variety of rocks such as the diverse collection of boulders found at Mount Washbourne.

[00:05:24] [SPEAKER_03]: Now these could be our first glimpses of the ancient rocks uplifted from depth by Jezero's

[00:05:29] [SPEAKER_03]: impact event now lying exposed on the surface of the crater rim. NASA Deputy Project Scientist

[00:05:35] [SPEAKER_03]: Katie Stack Morgan says these unusual new rock discoveries could be among the oldest that

[00:05:40] [SPEAKER_03]: Perseverance has ever investigated. On the other hand she says they could also be the youngest,

[00:05:45] [SPEAKER_00]: any time will tell. The Mars Perseverance rover is climbing out of the crater it landed on

[00:05:50] [SPEAKER_00]: and it's exploring rocks that are amongst the oldest we've seen on Mars or the youngest.

[00:05:58] [SPEAKER_00]: We're here in the Mars Yard at NASA's Jet Propulsion Laboratory. This is where we test robotic

[00:06:03] [SPEAKER_00]: prototypes as we explore Mars. Right now the real Perseverance rover is in the main channel

[00:06:08] [SPEAKER_00]: that once fed Jezero crater. Picture rushing water carrying big boulders and sediment as

[00:06:14] [SPEAKER_00]: it filled the crater but getting there was a slog. It was slow going through an area called the

[00:06:20] [SPEAKER_00]: margin unit which is really rocky and hilly but once we got out of the rocks we passed

[00:06:24] [SPEAKER_00]: through a dune field and it has been smooth sailing ever since. Now that we're in the channel

[00:06:29] [SPEAKER_00]: we're seeing things we've never seen before. Many of the boulders we see at the Martian surface

[00:06:35] [SPEAKER_00]: represent ancient lava flows that have broken up and eroded over time but a rock like this one

[00:06:40] [SPEAKER_00]: might have come from deeper in the crust and could be amongst the oldest rocks we've seen

[00:06:45] [SPEAKER_00]: or studied on Mars. It could also have come from the ancient rocks exposed nearby in the

[00:06:54] [SPEAKER_00]: rim though. We're making a stop at a site called Bright Angel. The rocks there could contain sediments

[00:06:59] [SPEAKER_00]: deposited by one of the last bursts of water into the crater and could be amongst the youngest rocks

[00:07:05] [SPEAKER_00]: we've looked at yet. Perseverance is equipped with cameras, geochemistry instruments and an

[00:07:10] [SPEAKER_00]: underground radar. We're going to use observations from these instruments to determine how and when

[00:07:15] [SPEAKER_00]: these rocks formed and depending on what we find we may decide to sample these rocks.

[00:07:20] [SPEAKER_00]: Whether Bright Angel is older or younger than what we've seen before in the crater

[00:07:23] [SPEAKER_00]: these rocks could be an important bookend to our Jezero sample collection. With Jezero in the

[00:07:29] [SPEAKER_00]: rear view mirror I'm most looking forward to this next phase of exploration on the crater rim.

[00:07:36] [SPEAKER_03]: And in that report from NASA TV we heard from NASA Deputy Project Scientist with the

[00:07:41] [SPEAKER_03]: Perseverance Project team Katie Stack Morgan. This is space time. Still to come!

[00:07:47] [SPEAKER_03]: Blue Origin's New Heavy Lift Rocket the New Glenn successfully completes its hot fire test of

[00:07:53] [SPEAKER_03]: its second stage booster and later in the science report have scientists finally discovered the

[00:07:58] [SPEAKER_03]: cradle of life. All that and more still to come on space time. Blue Origin's New Heavy Lift

[00:08:20] [SPEAKER_03]: Rocket the New Glenn has successfully completed a hot fire engine test of its second stage

[00:08:25] [SPEAKER_03]: booster. The critical test at Cape Canaveral Space Launch Complex 36 is a key step towards the

[00:08:32] [SPEAKER_03]: rocket's inaugural test flight slated for next month. The NG1 mission will carry the prototype

[00:08:37] [SPEAKER_03]: blue ring spacecraft as its first payload. The blue ring platforms are sort of space tug.

[00:08:43] [SPEAKER_03]: It's designed to be capable of refuelling transporting and hosting satellites. The New

[00:08:49] [SPEAKER_03]: Glenn launch will also serve as a national security space launch demonstration mission.

[00:08:54] [SPEAKER_03]: The 15 second hot fire test was the first time the vehicle operated as a fully integrated system

[00:08:59] [SPEAKER_03]: with both its BE3U rocket engines burning and both the launch vehicle subsystems and the ground

[00:09:05] [SPEAKER_03]: control systems operating simultaneously. These include not just the new BE3U engines but

[00:09:11] [SPEAKER_03]: also the helium system which keeps the liquid hydrogen and liquid oxygen tanks pressurized,

[00:09:16] [SPEAKER_03]: the thrust vector control system which steers the rocket using engine gimbling

[00:09:20] [SPEAKER_03]: and the engine startup and shutdown sequences which allow the BE3U rocket motors to be restarted

[00:09:26] [SPEAKER_03]: multiple times during the mission. The 98 meter tall New Glenn two-stage rocket is named after

[00:09:32] [SPEAKER_03]: John Glenn, the first American to orbit the earth. The upper or second stage features two BE3U

[00:09:39] [SPEAKER_03]: engines with an expanded bleed design that optimizes thrust performance. That means each engine

[00:09:44] [SPEAKER_03]: is initially rated for 160,000 pounds of thrust but it will operate at 173,000 pounds during the

[00:09:51] [SPEAKER_03]: NG1 mission. That makes these among the highest thrust to weight hydrogen engines ever used.

[00:09:57] [SPEAKER_03]: The giant reusable first stage is powered by seven BE4 engines, the most powerful liquefied

[00:10:03] [SPEAKER_03]: natural gas field oxygen-rich stage combustion engines ever flown. After each flight the

[00:10:08] [SPEAKER_03]: New Glenn first stage will return to earth landing on a badge called landing platform

[00:10:12] [SPEAKER_03]: vessel 1 and works now on the way to make the second stage reusable as well. Alongside the BE4

[00:10:20] [SPEAKER_03]: and BE3U engines, little origin also produces the BE7 engines for its blue moon lunar landers

[00:10:26] [SPEAKER_03]: and the BE3PM engines fitted to its new Shepard vehicle which is used for space tourism activities.

[00:10:32] [SPEAKER_03]: As with New Glenn, the new Shepard launch vehicle is reusable and named after an American

[00:10:37] [SPEAKER_03]: astronaut, in this case Alan Shepard who was the first American to reach space. This is space time.

[00:10:59] [SPEAKER_03]: Time that'll take another brief look at some of the other stories making news in science this

[00:11:03] [SPEAKER_03]: week with a science report. Researchers have discovered inorganic nanostructures surrounding

[00:11:09] [SPEAKER_03]: deep ocean hydrothermal vents that are strikingly similar to molecules that would make life as

[00:11:14] [SPEAKER_03]: we know it possible. A report in the journal Nature Communications claims these nanostructures

[00:11:19] [SPEAKER_03]: are self-organized and they act as selective ion channels which create energy that can then

[00:11:25] [SPEAKER_03]: be harnessed in the form of electricity. It works like this, when sea water seeps down into the

[00:11:30] [SPEAKER_03]: earth through cracks on the ocean floor it gets heated up by magma, it then rises back to

[00:11:35] [SPEAKER_03]: the surface and is released back into the ocean through fishes called hydrothermal vents.

[00:11:40] [SPEAKER_03]: The rising hot water contains dissolved minerals gained from the time it was deep inside

[00:11:45] [SPEAKER_03]: the earth and when it meets the cool ocean water chemical reactions force the mineral ions out of

[00:11:50] [SPEAKER_03]: the water where they form solid structures around the vents called precipitates. The study's authors

[00:11:55] [SPEAKER_03]: were studying samples collected from the Pacific Ocean's Mariana Trench at a depth of some

[00:12:00] [SPEAKER_03]: 5,743 meters. The Mariana Trench is the deepest part of the Earth's oceans. The key sample

[00:12:08] [SPEAKER_03]: which led to this discovery was an 84 centimeter piece composed mostly of brusite. Optical

[00:12:13] [SPEAKER_03]: microscopes and scans with x-rays revealed that the brusite crystals were arranged in continuous

[00:12:19] [SPEAKER_03]: columns that acted as nano channels for the vent fluid. The researchers noticed that the surface

[00:12:24] [SPEAKER_03]: of the precipitate was electrically charged and that the size and direction of the charge, positive

[00:12:29] [SPEAKER_03]: or negative, varied across the surface. They were able to show that the nanopores acted

[00:12:35] [SPEAKER_03]: as selective ion channels. At locations with carbonated heat to the surface the nanopores

[00:12:41] [SPEAKER_03]: allowed positive sodium ions to flow through. However at nanopores with calcium it hid to the

[00:12:46] [SPEAKER_03]: surface the pores only allowed negative chloride ions to pass through. It's not proof that it's

[00:12:52] [SPEAKER_03]: where life began but it's a tantalizing discovery. A new study has compared what people say in

[00:12:59] [SPEAKER_03]: public to what they really think in private. It turns out that although they don't like

[00:13:04] [SPEAKER_03]: to admit it people tend to self-censor themselves an awful lot to a far greater degree than

[00:13:09] [SPEAKER_03]: what was previously thought. The Massachusetts think tank populace together with you gov found that 61%

[00:13:15] [SPEAKER_03]: of Americans admit to self-censoring in other words keeping their true opinions on sensitive

[00:13:20] [SPEAKER_03]: topics to themselves. The study surveyed around 20,000 people. They found that while 36% of

[00:13:27] [SPEAKER_03]: Democrats and 14% of Republicans say they trust the government to tell the truth in reality

[00:13:33] [SPEAKER_03]: only 5% of Democrats and 2% of Republicans really believe that. And trust in the media was almost

[00:13:40] [SPEAKER_03]: as bad. While 42% of Democrats and 16% of Republicans said they trust the media to tell the truth

[00:13:46] [SPEAKER_03]: in reality just 9% of Democrats and 3% of Republicans really believe that the media

[00:13:52] [SPEAKER_03]: tells the truth. Also while 37% of Americans say the United States is a mostly fair country

[00:13:58] [SPEAKER_03]: deep down only 7% of people really believe that.

[00:14:03] [SPEAKER_03]: Scientists have isolated personality traits associated with self-control skills. A report

[00:14:09] [SPEAKER_03]: in the journal PLOS ONE has found that neuroticism, extroversion and conscientiousness are major

[00:14:15] [SPEAKER_03]: traits that impact how good your self-control is. The study's authors investigated the

[00:14:20] [SPEAKER_03]: relationship between five major personality traits and self-control among 480 military

[00:14:25] [SPEAKER_03]: cadets who had undergone personality testing. They looked for two types of self-control inhibitory,

[00:14:31] [SPEAKER_03]: the ability to resist temptation and the ability to initiate tasks to achieve long-term goals.

[00:14:38] [SPEAKER_03]: The authors say that participants who scored highly for neuroticism were likely to have lower

[00:14:42] [SPEAKER_03]: self-control in general and a lower ability to initiate tasks. They also found that higher

[00:14:48] [SPEAKER_03]: extroversion and conscientiousness scores were associated with higher self-control across

[00:14:53] [SPEAKER_03]: categories but less so when higher extroversion or conscientiousness also came together with

[00:14:58] [SPEAKER_03]: high neuroticism. The authors say personality traits impacted the two different types of

[00:15:03] [SPEAKER_03]: self-control in different ways showing the importance of distinguishing between them.

[00:15:09] [SPEAKER_03]: Well it's been a huge week in technology with meta showing off the new Orion augmented

[00:15:13] [SPEAKER_03]: reality glasses although at this stage it's only developer form and Huawei releasing their

[00:15:18] [SPEAKER_03]: new three fold cell phones. With the details we're joined by technology editor Alex Saharov-Royd

[00:15:24] [SPEAKER_02]: from TechAdvice.Live. Well at the MetaConnect conference they announced a whole series of

[00:15:28] [SPEAKER_02]: things one is the MetaQuest 3S which they're calling their most affordable mixed reality

[00:15:34] [SPEAKER_02]: headset so that's the latest version of their virtual reality headset that you can actually

[00:15:39] [SPEAKER_02]: see through but it's not designed really to be a pair of augmented reality glasses as such we

[00:15:44] [SPEAKER_02]: also have new meta AI with some celebrity voices people like Awkwafina, Dane Judy Dench, John Cena,

[00:15:52] [SPEAKER_02]: Keegan Michael Key and Kristen Bell so if you want your AI to sound like a celebrity you can do that

[00:15:58] [SPEAKER_02]: some new features for the Ray-Ban Meta glasses that pair of sunglasses that have AI inside that

[00:16:04] [SPEAKER_02]: they've got new features in there so you can remember things like where you parked or

[00:16:08] [SPEAKER_02]: translate speech in real time or answer questions about what you're saying but the big thing

[00:16:12] [SPEAKER_02]: that they announced was then you Orion smart glasses so this is their first true augmented

[00:16:18] [SPEAKER_02]: reality glasses a bit like what Apple has done with the Apple Vision Pro but instead of looking

[00:16:22] [SPEAKER_02]: like a giant pair of ski goggles these look like a normal pair of glasses obviously slightly

[00:16:28] [SPEAKER_02]: chunkier than what you'd expect from a pair of sunnies but instead of glasses got silicon

[00:16:32] [SPEAKER_02]: carbide the frames are magnesium can have multiple windows up in front of you like the Apple

[00:16:37] [SPEAKER_02]: Vision Pro you can have 3D holographic video calls and they're saying that's their most advanced

[00:16:43] [SPEAKER_02]: pair of glasses that they've had to make things very very small this is just a developer version

[00:16:49] [SPEAKER_02]: so it's not the commercial consumer version at scale yet they talk about having this in the

[00:16:54] [SPEAKER_02]: next few years but they talked about these AI glasses about a decade ago and here they are

[00:16:58] [SPEAKER_03]: this is really where we're going isn't it this is the future yeah you don't have to look in

[00:17:03] [SPEAKER_02]: your hand at a glowing glass rectangle but when you look out at something you can see

[00:17:07] [SPEAKER_02]: digital information just appearing overlaid on top of reality and because the glasses are looking

[00:17:15] [SPEAKER_02]: like a pair of regular glasses people can see your eyes so they're not seeing a digital representation

[00:17:19] [SPEAKER_02]: also it's not super heavy I mean you still have the battery you've got to put into your pocket

[00:17:23] [SPEAKER_02]: that haven't quite gotten the the batteries to go into the frames that can power this sort of

[00:17:27] [SPEAKER_02]: experience just yet that by 2030 these sorts of glasses should effectively be commonplace and

[00:17:33] [SPEAKER_02]: instead of having a smartphone you'll have your smart glasses on what was once science fiction

[00:17:37] [SPEAKER_02]: with a terminator and other movies it's not going to be reality this is a challenge laid down to

[00:17:42] [SPEAKER_02]: Apple when Apple obviously also will get their Vision Pro headset down but Apple didn't launch a

[00:17:47] [SPEAKER_02]: developer kit they launched something for the public and I've tried the Vision Pro it is

[00:17:51] [SPEAKER_02]: stunning I mean it's incredible but after 20 30 minutes you can feel the weight you

[00:17:55] [SPEAKER_02]: definitely won't feel the weight with these particular glasses from Meta the graphics don't

[00:17:59] [SPEAKER_02]: look as good as what I see on the Vision Pro but still looks pretty amazing the question is though

[00:18:04] [SPEAKER_02]: do you trust Apple more than you trust face and the other big news I thought was Huawei's new

[00:18:09] [SPEAKER_02]: three-fold yeah now I'm speaking to you on an iPhone but I'm looking at my Google Pixel Pro fold

[00:18:15] [SPEAKER_02]: nine which is the second generation which is very thin that's got two screens the Huawei

[00:18:21] [SPEAKER_02]: equivalent has three screens so it unfolds into a 10.2 inch tablet each folding piece is quite thin

[00:18:27] [SPEAKER_02]: so when you fold it up it is thicker than a regular phone but it does look quite stunning

[00:18:32] [SPEAKER_02]: when you see the videos of this online now you do have two sets of creatures because you've got

[00:18:37] [SPEAKER_02]: three paints that have to fold out and they will figure out how to make that completely

[00:18:40] [SPEAKER_02]: flat one day of course with the Huawei version I mean it's $2,800 US that's you know over

[00:18:46] [SPEAKER_02]: $4,000 Australian they did have four million pre-orders in China but definitely this is the

[00:18:51] [SPEAKER_02]: future of this small and unfolded. This will take us to 2030 when the glasses become commonplace.

[00:18:56] [SPEAKER_02]: Well it's going to be a mixture of the two I mean you're still going to want to have devices you

[00:19:01] [SPEAKER_02]: can hold that will fold down into something small and unfold okay but you'll also want to have

[00:19:04] [SPEAKER_02]: the glasses I mean I can imagine that there'll be things I will want to see on the screen the

[00:19:08] [SPEAKER_02]: things I want to see in my field of view there's going to be use cases for all of those

[00:19:12] [SPEAKER_02]: devices one's not going to replace the other immediately certainly not in the short term

[00:19:16] [SPEAKER_03]: that's Alex Harrow Roy from techadvice.life that's the show for now. Spacetime is available every
