[00:00:00] Stuart: This is space time series 25 episode five, four broadcast on the 12th of January, 2022. Coming up on space time, a failed Russian rocket crashes back to worth in an uncontrolled re-entry exploring the Jovian ice moon Europa and tests continues. Its mission searching for planets, orbiting, distance stars, all that and more coming up on space-time
[00:00:27] VO Guy: welcome to space time with Stuart, Gary.
[00:00:47] Stuart: failed Russian test launch has seen a four ton rocket stage crash back to earth in a fiery uncontrolled re-entry the burning debris from the end Garah rocket Percy, the upper stage slammed into the south Pacific ocean, Easter French Polynesia mission managers had no idea where or when the wildly tumbling space craft was going to re enter the atmosphere and consequently, where it would hit the surface.
The exact dynamics of the re-entry, we're going to be dependent on the rate of overall decay. The amount of atmospheric drag the spacecraft was encountering and how evenly that drag was distributed around the planet. Even the attitude of the spacecraft as it skipped across the upper layers of the atmosphere would have played apart after nine days of uncontrolled space flight, the Percy with its payload, still attached, reenter the us atmosphere as a brilliant fireball, hitting the ocean.
Surely after. The mission had originally loads from the placenta Cosmodrome 800 kilometers north of Moscow. The flight was the fourth test of Russia's new and Gara heavy lift rocket named after a Siberian river that flows out of lake by cow and Garris designed to replace the aging proton as Russia's new heavy lift launch vehicle.
And this one was also designed to test the new Percy upper stage booster, which would carry the flight's dummy payload from low-earth orbit up into a higher geostationary transfer orbit while the is for strap on boosters, core stage and third stage all before nominally, the Percy upper stage fell to re-ignite for a plan second engine burn, leaving it with its dummy payloads, still attached in a useless out of control.
Misha managers weren't even sure if the Percy had vented the remainder of it. 16 tons of rocket fuel locally that a breed came down in the ocean, but it could have been so much worse. Moscow has faced major cleanup builds on past fouled missions with highly toxic hypergolic fuels, contaminating, vast areas and spacecraft, the debris crashing the villages in 1996.
Russia's Feld Verbus grant mass probe crashed to the ground in Chile and Argentina. The worst ever radiation spill from a crash spacecraft was back in January, 1978. When the nuclear powered Soviet union cosmos 9 5, 4 satellite crashed over south Western Canada development of the injera loan system began exactly 30 years ago.
Following the collapse of the former Soviet union. The 47 meter tall launch vehicle is designed to carry 24 and a half tons into low earth orbit and almost eight times in a geo station. We transfer. The suborbital maiden flight of the core stage took place in July, 2014 with the a five version. That's the one where the strap on boosters undertaking its first orbital flight.
In December of the same year, the only the other Angora flight was in December, 2020. When a breeze M upper stage was added to the stack. This is space time. Still to come next is Europa clipper mission to explore the Jovian ice moon Europa and test continues its mission search for planets orbiting stars beyond the sun, all that and more store to come on.
Back in 2005 images of a brilliant watery plume erupting from below the surface of satins ice moon Enceladus, captivated, the world, the giant Geyser of vapor ice particles and organic molecules spraying out of the moon. South pole tiger stripes region suggested there must have been a liquid water ocean below, and sodas is IC.
The discovery, thrust and solace as well as other worlds in the outer solar system with no atmospheres and far from the heat of the sun, towards the top of masses list of places to search for signs of life and scientists are now preparing for a mission to one of these ice covered ocean worlds, one, which may also have plumes erupting into deep space.
The Jovian ice moon Europa. Shattered full launch in 2024 NASA's Europa clipper mission will study the moon, trying to determine whether it would have the ingredients to make it a viable home for life beyond earth. Like Enceladus Europa is geologically dynamic, meaning that both ice covered moons generate heat inside.
As they're solid, internal layers are stretched and flexed by the gravitational pull of their host planets and neighboring moon. See it's friction from these gravitational tidal forces rather than hate from the sun, which presents the water in these worlds from freezing sold. The hate may also help reduce or circulate life's chemical building blocks on their sea floors, including carbon, hydrogen, oxygen, nitrogen phosphorus, and sulfur.
After all the hydrothermal vents along the mid-ocean ridges on earth, sea floors are teaming with life and many scientists speculate. It may even be where life on earth began. Europa clipper scientists, Leanne quick from NASA Goddard space flight center in Greenbelt, Maryland. It says a lot of people think Europa is going to be a sort of Enceladus 2.0 with watery plumes, constantly spraying out from below the surface, but that's not the case.
Europa is a totally different beast. Observations from messes Galileo mission and the 1990s, as well as images by Hubble and large earth based telescopes have reported detections of faint water plumes, or at least the chemical compounds in Europa's thin atmosphere. But no, one's really certain that astronomers are drawn to plumes for several reasons.
Firstly, they offer scientists easy access to Europa's interior, a way to get samples of the moon's global subsurface ocean without needing to drill through more than 25 kilometers of solid ice sheets. Now, compared to Enceladus, which is the size of Texas Europa is only slightly smaller than the Earth's moon, about a quarter of the size of earth itself.
And the evidence suggests Europa has a far deeper salt water ocean than in, so at us, possibly somewhere between 60 and 160 kilometers. That means it contains two to three times as much water as the Earth's oceans. And some scientists hypothesize that Europa's oceans could be reacting with super-heated rocks below the sea floor, possibly through hydrothermal vents, just like on earth.
Scientist said there could also be large pockets of melted water in Europa's ice shell, which are more likely than the ocean to be a source of the plumes. And these melted water pockets could produce cozy habitats for life. Because it's much closer to Jupiter than in solid assist. The satin Morehead's generated Europa from friction, producers, it circles.
It says planet. Now, given that internally, it stimulates geological activity on Rocky worlds. Europa it's expected to have more extensive geology. Then Enceladus some side has predict that Europa has Playtech tonics. These would shift and recycle the ice sheets that make up the moon's surface. Now if so Europa could be circulating nutrients produced on the surface by radiation, from Jupiter, such as oxygen, the pockets of liquid water in the ice show, or perhaps even down to the ocean itself through the Europa clipper mission scientist will have a chance to test some of their hypotheses by analyzing the chemical makeup of the plumes or traces.
They leave behind them. Surface mind you, the Rogan plumes. If they exist, might, will be hard to detect even close. They may be sporadic and they may be really small and thin given that Europa is gravity, which is much stronger than Enceladus would likely keep these water plumes close to the surface. So that means a drastic departure from Enceladus as spectacular guises, still Europa clipper scientist.
I'd advising a variety of strategies to find active plumes. Once the spacecraft begins exploring the Jovian ice moon in 2031, that's just nine years away. We'll keep you informed. This is space time still. The com NASA is transit exoplanet survey, satellite tests now willing to it's extended mission and Russia's let us space tourists return home, all that, a more store to come on.
NASA is transiting exoplanet survey. Satellite tests is now willing to it's 27 month extended mission. Having already identified more than 2,600 candidate exoplanets. That is planets orbiting stars, other than the sun tests, such as for exoplanets using the transit method. And it covers an area 400 times larger than that surveyed by its predecessor.
The planet hunting capital space. Tell us. Tess was launched on April the 18th, 2018, about a Falcon nine rocket and placed into a highly elliptical 13.7 day orbit was an Apogee of over 400,000 kilometers, which is approximately the distance to the moon and a pair of G of a hundred, 8,000 kilometers, three times further out from the earth that geostationary satellites, the spacecraft primary mission was to survey the brightest stars near earth for two years, looking for transiting exoplanet.
The 362 kilogram satellite uses an array, a widefield cameras to perform a survey of 85% of the sky to search for exoplanets, Tess watches, a 24 by 96 degrees section at the sky for 27 days at a time. Some of these sections overlap. So some parts of the sky were observed for almost a year. Tests concentrated on stars within 300 light is of the sun watching for transits.
That is periodic dips in the brightness of a star caused by an object. Say a planet passing in front of the star is seen by tests with tests. It's possible to study the mass size density and orbit of a large cohort of small planets, including a sample of Rocky planets in the habitable zones of their host star.
The habitable zones, those areas around a star where it's not too hard and not too cold, but just right for liquid water central for life. As we know it to exist on a planet surface test provides prime targets, which has been examined in more detail by Hubble or ground-based observatories. And soon by the James Webb space, tell us.
Well, previous guy surveys with ground-based telescopes have mostly detected gas giants and Kepler space. Telescope is mostly found pilots around very distant stars to faint for characterization. Test finds many small planets around nearby stars in the sky that qualifies an exoplanet candidate and the object must make at least three transits in the test day.
It then passes through several additional checks to make sure these transits are real and not false positives caused by an eclipse or a companion star tests began heading for exoplanets in the Southern sky in July, 2018, while also collecting data on supernova, black holes and other phenomenon it's line of sight after completing the Southern portion of its initial survey in July, 2019, this began searching the Northern skies, completing that survey in July, 2020.
It then began its extended mission, which includes a new set of target stars, increased frequency, imaging, and observations of regions near the ecliptic. This report from NASA TV
[00:12:32] Narrator: tests, the transiting exoplanet survey satellite is NASA's newest planet hunter with mountains of data to analyze scientists have just scratched the surface of what they can learn.
Here are some noteworthy discoveries from Tessa's first year in September, the test team released the first of 26 planned sector images. Each sector is a 24 by 96 degree strip of sky monitored by is four cameras. By the end of 2018. Test began delivering on its promise to discover new worlds around nearby bright stars.
When astronomers announced the mission's first new exoplanets. In April, 2019 one year after launch astronomers announced the discovery of test is first birth size exoplanet orbiting, a relatively nearby star. This world is likely too hot to support life, but it proved that test could find small planets that orbit very close to them.
Test has now found several multiplet systems where small planets orbit nearby stars just as it was designed to do many are not in the habitable zone, like the planets in the L 98 59 system, but all are teaching us more about the wide range of planets out there. Even before starting its hunt for exoplanets test was making observations to test its cameras in late July, 2018 test image to passing.
Along with many asteroids in our solar system later in the year test went from seeing comments, orbiting our sun to comments, orbiting other stars. It's camera spotted fluctuations in light from the star beta pick tourists that are now recognized as the signatures of three comets passing in front of the star.
They joined planets already discovered in this young nearby system. Although designed to look for exoplanets test also spots, many supernovae bright explosions that mark the deaths of stars its cameras can catch these outbursts from their very start. Even before ground-based surveys, identify them. Tess has already expanded our understanding of new worlds, close to home and exploding stars beyond our galaxy.
[00:14:48] Stuart: This is space time still to come. Russia wraps up its latest space, tourism mission, and later in the science report and you study, it looks at why people binge out on TV, all that the most. Um, space-time
two Japanese space, tourists and a Russian cosmonaut have returned safely to earth about this. So is Ms. 20 caps? The trio landed on the windswept cosmic stand step three and a half hours after undocking from the Zenith port aboard the international space stations, ports module,
[00:15:36] Guest: the two space flight participants, um, closing hatches along with the Soyuz commander Alexander.
Saying goodbye to Anton scapular off the expedition, 66 commander and all three crew members they're waving goodbye to their, uh, short-term crew mates.
[00:15:56] Alex: no
[00:15:57] Guest: long day eliminated. And, um, we confirm physical separation. So, um, so one and the two to five there we are sending. Who are the first separation burn
and burn. And that's where the
threat and awaken from the.
again, RuPaul. We are done with the maneuver.
well, I'm standing by for the seventh separation. Copy
firing is no longer
[00:16:58] Alex: eliminated. The
[00:17:01] Stuart: space. Tourists have been on a 12 day adventure to the opening outpost, the Russian federal space in Euro's cosmos. This is bad weather and frigid conditions delayed the helicopters from reaching the landing site after touchdown. However, all three appeared to be in good health and in good spirits in the circuit launch.
And re-entry spacesuits when they were finally assisted out of the Soyuz capsule.
[00:17:23] Guest: Okay. And we are now receiving the, the, uh, recovery crews are with the soil. They arrived. 9:33 PM. Central time, um, site, the landing site and the crew is feeling good. The scent module is vertical. May not get a final landing, exact landing time, but it was scheduled for nine, 13:00 PM central time.
And once again, we do have confirmation now that the recovery teams are with the sole use it didn't. Landa bright and it's and it's nominal position, or there's possible for it to land on its side. And that's not a problem, but this will hopefully speed recovery efforts along a little bit, again, the, um, recovery crews and those, uh, Mia helicopters and, uh, the all-terrain vehicles have made it to the Soyuz landing site.
And. Should not be working on extracting the, the crew from there. So used vehicle again, wrapping up at 12 days in space, 189 orbits and 4.6 million miles that Sekou Mazola and USAA Herano have traveled in the course of their flight led by Soyuz commander, Alexandra Serkan, who was making his third trip to space.
He is wrapping up. But 346 days
[00:18:33] Stuart: spent in space space adventures. The company that broke his space, tourism flights with rods, cosmos hasn't disclosed how much the flight costs the tourists, but we know the first space tourist Dennis Tito paid around $20 million for his seven day adventure to the space station.
That was the board, saw his team 32 back in mid 2001. And we know Russia charges NASA between 60 and $90 million for a seat on a soil. Spacetime
and time now to take another brief, look at some of the other stories, making use insights this week with a science report, a new study warns that the amount of rainfall and the Arctic may increase at a faster rate than previously. The findings were reported in the journal nature communications show that the turtle rainfall could supersede snowfall in some parts of the Arctic by 20, 60 decades earlier than expected.
The authors argue that more stringent climate mitigation policies are required as a rainfall dominated, Arctic would have impacts on ice sheet, melting rivers and wild animal populations, and would have important social, ecological, cultural, and economic implications. Northrup Grumman has started work on that.
First of Australia, new MQ foresee trite and high-altitude aircraft based on the original global Hawk. The new long range reconnaissance and surveillance drones will have the same intelligence gathering capabilities as the U S Navy's new Tridents, which are now being commissioned into service. The first Australian air force, try it and the should be flying in RC skies by 2020.
And you studied claims that the desire to escape boredom is the main reason people binge watch TV on streaming services. The findings are reported in the journal. Front is a psychiatry suggest that people with a lack of impulse control forethought are more likely to binge watch TV at problematic rates.
Researchers surveyed over 600 people aged 18 to 30, who have watched more than one episode of a TV show in a single cell. They say that paper with impulse control difficulties, a desire for escapism and those looking to avoid loneliness. We're more likely to binge-watch with one in five saying that watch between six and 20 episodes in a single sitting, the researchers say more studies and needed the drawer align between healthy and unhealthy.
Binge-watching the world's largest consumer electronic show CES has provided us with another glimpse of the future of technology. While somewhat reduced in size this year. Thanks to COVID the best of tomorrow's gadgets. We're still on display at the show in Las Vegas. This is highlights included the latest in AK flatscreens a robotic shift, their cooks gourmet meals, identical down to the molecular level with a finest recipes, a battery powered mini projected that plugs into your smartphone to display pictures or movies anywhere you want.
There was a holographic device for three dimensional communications, a car that can change color and an autonomous robotic tractor that does all the work for the farm. With the details we're joined by technology editor, Alex Herrera, Roy from ity.com. Who's at CA
[00:21:50] Alex: Samsung has the remote control, for example, but not just solar powered with ordinary batteries as well inside, but it can pick up energy from the radio frequency from your, my phone.
And that is something we'll see in neural phones and other devices. Over the course of these decades, I saw a company here called , which makes a RF. For wireless power and things, a full smaller devices that aren't ready yet for phones, you could actually say Motorola. And as I show a demo in 2021, I'll just technology at work, but you walk in front of it, the charging stop.
Now there's Doosan, Bobcat, it's current company that bought the Bobcat rent and they have the world's first, fully electric. And instead of just having hydraulic attachments to pick up dirt and to move things around, this is all electric, basically. I think there's actuators. And so there's not a hydraulic fuel.
You have one quarter of some sort of oil, as opposed to 57 gallons of hydraulic fluid that would have to use it's using electricity rather than diesel and give you four hours of constant non-stop use or eight hours of a sort of normal usage and actually use that. So the screen in front of you, that you look out of your windshield as such, he's actually the, uh, control center for the unit.
Now, obviously you have steering wheels and other things in front of you to control things, but you have all this digital information that would otherwise be on an LCD screen, but here it's actually. On the front of the screen. And so transparently like something out of a science fiction yet, like something out of a science fiction movie, it's, you're tapping the screen icon.
And you can imagine that this is the sort of thing that would be used in future moon buggies. Clearly this sort of technology would be perfect to use on Basel on the moon where you're not going to have easy access to hydraulic fluid. You'll have plenty of access to solar energy to recharge things and to run around.
And you have that industrial kind of design and capacity that you would made before a moon mission or my vision. There was a thing called. Q you beat up a lawyer, which launched a couple of years ago. It's like a cat that sits on your lap with a tail, but it has no legs in their head and it sort of wags this tile and moves around.
And it's great for, um, you know, all older people in homes and people have. Want to have a pet Baton habit
dress up for the middle capital cost. Does it need to have the cat litter change? So certain people that best provide a level of comfort that otherwise they wouldn't get, even though it's not official and doesn't do much more than just a wriggle around them and a flag it's tiles, but you know, that'd be successful.
And I have another product, which is like a, another looks like more like an actual cat or a little. And you, you put your
[00:24:18] Stuart: finger in his mouth
[00:24:21] Alex: and it is sort of general. I put my finger in. It's like fucking on your finger. It's some sort of motor in there that is so pushing down. And it's just one of those things where, you know, for some people it's completely useless.
Th th the, um, one of the staff members of the organization said, well, they missed it. You know, their little child's doing that to them. And I don't know if this is a part of that that's put out there. It's had an interesting response. They're going to make it, we're going to see these devices to come a lot more realistic.
I mean, another gadget that I saw was this human body and the design for kids. We didn't have an app that you could pull all of the body parts out, you know, the intestines, the lungs pull the legs that could have all these different parts of the body. You could pull the two hemispheres of the brain app.
And you could put the, the buddy pot on the pad and the paddock would then tell you what that body part was. Interesting facts about different parts of the body. And it was a screen-free, you know, required no app, something that teaches kids, young kids about the anatomy of the
[00:25:17] Stuart: human body, from what you've seen so far.
Thing that gobsmacked you, the thing that you thought, wow, this is real.
[00:25:25] Alex: The Bobcat that was fully electric with a touch screen, transparent, despite the touch screen, transparent display reminded me of the phones that you see in the scifi TV show, the expense, which looked like he'd read about LG. Parents displays before I came to see us.
But when Bobcat was talking about it, I said, well, that worked with LTE. And then you can start just by technology. So he was a practical application because otherwise, why would you want your TV to have a transparent display? You wouldn't because you would see the back of the wall and all the cables that'll plug into the back of it.
But he was a pivot to applications that transformed the windshield into a usable, useful patched green that is not impeding. And he's delivering real-world benefits to the user. So, you know, one of the things that that Bobcat was able to allow you to do was control other Bobcat in other parts of the country through 5g.
So you can control multiple units from the one unit you're hitting in through my control and through the low latency that 5g provides. So this enables you to have not only the control without the repair costs and all the. But also delivers a very quiet experience as I think that was saying 10 times quieter than your traditional diesel powered equipment.
[00:26:34] Stuart: Question. I always ask about CES is do they have an affordable flying car because I'm really waiting for my flying car, but yet the hoverboards I've given up on that, it's the flying car. The
[00:26:45] Alex: biggest thing that's going to be a problem for the flying car is the ability to get the regulatory approval for you to fly it.
Because if you slide and you accidentally crashed, you're going to land. And that's why we don't have flying cars yet, besides the fact they're expensive and they're noisy and they haven't got the full effect ride and a, you need to have the right sort of fuel where you trust electric technology to have enough power.
I mean, I haven't had drones that were flying, flying taxi, and that's using title nine rotors or whatever it might be. So the flying path, there's been a lot of talk about that. Well, the 50 years since we've had
[00:27:16] Stuart: the Jetson, Justin was born in 2022. Well, if that was
[00:27:20] Alex: the case, I mean, he's probably 30 or 40 in the TV show.
So we still got a few years. If not decades ago, before flying cars truly become something affordable and reliable and safe enough that you wouldn't have people who are drunk or otherwise having a medical episode or something crashing their flying, tired your house. It could be a terrible, terrible thing.
