Speaker 1: Welcome to Astronomy Daily. I'm Steve your host. It's the
Speaker 1: sixteenth of the ninth, twenty twenty four.
Speaker 2: The podcast with your whole Steve gun Crude.
Speaker 1: Yes, welcome and welcome to Astronomy Daily. We have a
Speaker 1: terrific collection of stories right off the Astronomy Daily newsletter
Speaker 1: for you today, and Hallie will share with you something
Speaker 1: from down Under, in fact, way down under, all the
Speaker 1: way from gorgeous Adelaide in South Australia where they are
Speaker 1: working on hypersonic technology. Great story. We'll have a look
Speaker 1: at the next chapter for Boeing and Starliner, following the
Speaker 1: long stay at the ISS and the uncrude re entry
Speaker 1: of that craft. That'll be interesting. And did you know
Speaker 1: there's a partial lunar eclipse coming shortly. I think Halle
Speaker 1: has the details for that one as well. I saw
Speaker 1: her going through the calendar a while ago, so I'm
Speaker 1: sure she's got those details. The big news of this week,
Speaker 1: of course, was the flight of Polaris Dawn. If you
Speaker 1: were under a rock or asleep like I was, you'll
Speaker 1: probably might have missed some of it. But he safely
Speaker 1: returned to Florida yesterday. That's our time here in Australia.
Speaker 1: But anyway, returned to Florida and there's another story filed
Speaker 1: here somewhere on Malli.
Speaker 2: Where did you put it? Helle?
Speaker 3: Helly?
Speaker 1: Helle? Ah, Helle, crazy kids? Found my record collection again?
Speaker 1: That's David Bowie. Halle turn it down? Oh cool?
Speaker 2: Hey?
Speaker 1: Have you been going through my record collection again?
Speaker 4: Final Human? Really?
Speaker 2: Yeah? Really?
Speaker 4: And David Bowie, Oh the star.
Speaker 2: Man, I mean, the coolest man on the planet.
Speaker 4: Okay, I'll give you that one. But you know why
Speaker 4: I pulled that song out, don't you.
Speaker 2: Ah? Yes, sir, I remember what the story is now.
Speaker 4: It's the spiders from Mars.
Speaker 2: It's just too cool for school, isn't it.
Speaker 4: Helly so weird? Do you think he knew all those
Speaker 4: years ago?
Speaker 2: Oh? I don't know.
Speaker 1: No, he was pretty weird back in the day though.
Speaker 1: I mean it was a great song. If you don't
Speaker 1: know who we're talking about, we're talking about David Bowie
Speaker 1: and his song Ziggy Stardust and the spot is from Mars,
Speaker 1: coincidentally preempting a story on the Astronomy Daily newsletter this week.
Speaker 4: Just a coincidence, of course, or is it you're freaking
Speaker 4: my bits?
Speaker 3: Now?
Speaker 4: Human? Should I do some stories.
Speaker 2: Yeah, keep on truck and Halle lay them on a.
Speaker 4: Sister, so groovy. All of a sudden.
Speaker 2: Ground control to Helle, I was never cool.
Speaker 4: It's news time, Roger that my favorite human. South Australia
Speaker 4: is set to enhance its position as a global aerospace
Speaker 4: hub following a memorandum of understanding between Southern Launch, a
Speaker 4: prominent spaceport provider, and Hypersonics Launch Systems, a Queensland based
Speaker 4: developer of hypersonic vehicles and scramjet technology. The memorandum outlines
Speaker 4: a collaboration to develop a hypersonic testbed service that will
Speaker 4: utilize Southern Launch as spaceports for testing. Hypersonics is known
Speaker 4: for its expertise in designing and manufacturing hypersonic vehicle technology
Speaker 4: and scramjet engines, and this agreement will see the two
Speaker 4: companies working together on a mission to launch and return
Speaker 4: Hypersonics's test bed vehicles utilizing either of Southern Launches spaceports.
Speaker 4: South Australia has some geographical advantages that make it the
Speaker 4: perfect place to test hypersonic vehicles. Hypersonic aircraft travel at
Speaker 4: speeds exceeding five times the speed of sound and require
Speaker 4: extensive space for testing. Hypersonics's aircraft will be launched on
Speaker 4: a rocket and will ignite its scramjet engines to achieve
Speaker 4: speeds of up to mock twelve. There are a huge
Speaker 4: number of both emerging technology companies and large aerospace companies
Speaker 4: that need hypersonic flight heritage for their products, and the
Speaker 4: intensity of hypersonic testing is set to rise rapidly. Hypersonic
Speaker 4: CEO Matt Hill said, our hypersonic test bed will make
Speaker 4: it more affordable for these companies to flight qualify their technology.
Speaker 4: The companies are set to collaborate on a concept for
Speaker 4: the future commercial launch and return of a hypersonics test
Speaker 4: bed vehicle. Hypersonics's long term goal is to provide affordable
Speaker 4: aircraft like access to space, with spacecraft deployed at the
Speaker 4: edge of space and returning to Earth like an airplane.
Speaker 4: The technology also holds the promise of powering future passenger aircraft,
Speaker 4: potentially reducing flight times from Adelaide to London to just
Speaker 4: two hours. And yes, human I found the next eclipse
Speaker 4: in the calendar. It only took a nanosecond, of course,
Speaker 4: and it turns out we get a bonus with this one.
Speaker 4: So get ready for a partial lunar eclipse and supermoon
Speaker 4: all rolled into one. The spectacle will be visible in
Speaker 4: clear skies across North America and South America Tuesday night,
Speaker 4: and in Africa and Europe Wednesday morning. A partial lunar
Speaker 4: eclipse happens when the Earth passes between the Sun and Moon,
Speaker 4: casting a shadow that darkens a sliver of the Moon
Speaker 4: and appears to take a bite out of it. Since
Speaker 4: the Moon will inch closer to Earth than usual, it'll
Speaker 4: appear a bit larger in the sky. The supermoon is
Speaker 4: one of three remaining this year. A little bit of
Speaker 4: the Sun's light is being blocked, so the Moon will
Speaker 4: be slightly dimmer, said Valerie raps In, an astronomer at
Speaker 4: the State University of New York. At ONEONTA. The Earth,
Speaker 4: Moon and Sun line up to produce a solar or
Speaker 4: lunar eclipse anywhere from four to seven times a year,
Speaker 4: according to NASA. This lunar eclipse is the second and
Speaker 4: final of the year, after a slight darkening in March.
Speaker 4: In April, a total solar eclipse plunged select cities into
Speaker 4: darkness across North America. No special eye protection is needed
Speaker 4: to view a lunar eclipse, viewers can stare at the
Speaker 4: Moon with the naked eye, or opt for binoculars and
Speaker 4: telloscopes to get a closer look. To spot the Moon's
Speaker 4: subtle shrinkage over time, hang outside for a few hours,
Speaker 4: or take multiple peaks over the course of the evening,
Speaker 4: said cauch On, you, curator at the Denver Museum of
Speaker 4: Nature and Science. It will take some time for you
Speaker 4: to see the difference, but as good skywatchers know, it's
Speaker 4: all about the observations and being patient for a more
Speaker 4: striking lunar site. Skywatchers can set their calendars for March thirteenth,
Speaker 4: the Moon will be totally eclipsed by the Earth's shadow
Speaker 4: and will be painted red by stray bits of sunlight
Speaker 4: filtering through Earth's atmosphere. I Run on Saturday blasted a
Speaker 4: new research satellite into orbit, State Media said, in the
Speaker 4: latest such development for an aerospace program that has long
Speaker 4: faced Western criticism, the Shameran one research satellite was successfully
Speaker 4: launched and put into orbit by the game one hundred carrier.
Speaker 4: State Television said. The satellite, which weighs around sixty kilograms
Speaker 4: or one hundred and thirty two pounds, is designed to
Speaker 4: test hardware and software systems for orbital maneuver technology, the
Speaker 4: report said. It also stated that the device was designed
Speaker 4: and built by Iranian electronics industries affiliated with the Defense ministry.
Speaker 4: Western governments, including the United States, have repeatedly warned Iran
Speaker 4: against such launches, saying the same technology can be used
Speaker 4: for ballistic missiles, including ones designed to deliver a nuclear warhead.
Speaker 4: Iran has countered that it is not seeking nuclear weapons
Speaker 4: and that its satellite and rocket launches are for civil
Speaker 4: or defense purposes only. The Game one hundred rocket, which
Speaker 4: carried the latest satellite, is manufactured by the Aerospace Organization
Speaker 4: of Iran's Revolutionary Guard Corps, an arm of the military.
Speaker 4: The carrier is the country's first three stage solid fuel
Speaker 4: satellite launcher, and official media reported its use in January
Speaker 4: to send a satellite for the first time into an
Speaker 4: orbit above five hundred kilometers or three hundred and ten miles.
Speaker 4: Iran has for years been advancing its aerospace activities, insisting
Speaker 4: they are peaceful and in accordance with United Nations Security
Speaker 4: Council resolutions. In February, Russia put into orbit an Iranian
Speaker 4: remote sensing and imaging satellite drawing condemnation from the United States.
Speaker 4: At the time, Iran's telecommunications minister said Iran had carried
Speaker 4: out a dozen satellite launches over the previous two years.
Speaker 4: Iran in January said it simultaneously sent three satellites into orbit,
Speaker 4: nearly a week after the launch of a research satellite
Speaker 4: by the Guards. The Islamic Republic has struggled with several
Speaker 4: satellite launch failures in the past. Iran has suffered years
Speaker 4: of crippling Western sanctions, especially after its archfaux. The United States,
Speaker 4: under then President Donald Trump in twenty eighteen, unilaterally abandoned
Speaker 4: a landmark nuclear deal between Tehran and major powers. Iran
Speaker 4: on Thursday summoned four European ambassadors after they imposed new
Speaker 4: sanctions over its alleged supply of ballistic missiles to Russia
Speaker 4: for use in Ukraine, which Tehran denies.

Speaker 1: Astronomy with Steve and Halee Space Space Science and Astronomy.
Speaker 1: Boeing's crew transport space capsule the Starline a return to
Speaker 1: Earth without its two person crew right after midnight Eastern
Speaker 1: time on September seven. Its remotely piloted return marked the
Speaker 1: end of a fraught test flight to the International Space Station,
Speaker 1: which left two astronauts, Books Wilmore and Sanita Sunny Williams
Speaker 1: on the space station four months longer than intended after
Speaker 1: thrust failures led NASA to deem the capsule unsafe to
Speaker 1: pilot back. Wilmore and Williams will stay on the ISS
Speaker 1: until February twenty twenty five, when they will return to
Speaker 1: Earth on a SpaceX Dragon capsule. NASA awarded contracts to
Speaker 1: both Boeing and SpaceX in twenty fourteen to provide crew
Speaker 1: transport vehicles to the ISS via the commercial crew program.
Speaker 1: At the start of the program, both most bets were
Speaker 1: on Boeing to take the lead because of its extensive
Speaker 1: aerospace experience. However, SpaceX moved very quickly with its new
Speaker 1: rock at the Falcon nine and its cargo ship Dragon.
Speaker 1: While they suffered some early failures during testing, they aggressively built, tested,
Speaker 1: and learned from each failure. In twenty twenty, SpaceX successfully
Speaker 1: launched its first test crew to the ISS Space Station. Meanwhile,
Speaker 1: Boeing struggled through some development setbacks. The outcome of this
Speaker 1: first test flight is a huge disappointment for Boeing and NASA,
Speaker 1: but NASA's leadership has expressed its support for Boeing believe
Speaker 1: it remains the agency's best interest to have more than
Speaker 1: one American crew launch system to support continued space operations.
Speaker 1: NASA is also continuing to engage partnership with Russia. This
Speaker 1: partnership provides the agency with multiple ways to get crew
Speaker 1: members to and from the space station. As space station
Speaker 1: operations continue, NASA and its partners have enough options to
Speaker 1: get people to and from the station that they'll always
Speaker 1: have the essential crew on the station even if there's
Speaker 1: launch disruptions for any one of the capable crewed vehicles.
Speaker 1: Having Starliner as an option will help that with that redundancy.
Speaker 1: At the moment, Boeing is going head to head with
Speaker 1: space X. Now, the SpaceX Dragon crew spacecraft has several
Speaker 1: flights under its belt and it's proven a reliable way
Speaker 1: to get to and from the space station. It's important
Speaker 1: to remember that this was a test flight for Starline.
Speaker 1: Of course, the program managers want each test flight to
Speaker 1: run perfectly, but you can't anticipate every potential problem through
Speaker 1: ground testing. Unsurprisingly, some problems crop up and you expect
Speaker 1: them in a test flight. The space pro environment is unforgiving.
Speaker 1: A small problem can become catastrophic in zero gravity. It's
Speaker 1: hard to replicate these situations on the ground. The technology
Speaker 1: SpaceX and Boeing use is also radically different from the
Speaker 1: kind of capsule technology used in the early days of Mercury,
Speaker 1: Gemini and Apollo programs. NASA has evolved and made strategic
Speaker 1: moves to advance its mission over the past two decades.
Speaker 1: The agency has leaned into its legacy of thinking outside
Speaker 1: the box. It was in innovative move to break from
Speaker 1: the tradition and leverage commercial competitors to advance the program.
Speaker 1: NASA gave the companies a set of requirements and left
Speaker 1: it up to them to figure out how.
Speaker 2: They would meet them.
Speaker 1: As for but Wilmore and Sonny Williams, they are considered
Speaker 1: rock solid professionals, and it's believed that their first thoughts
Speaker 1: are about completing their missions safely. They are both highly
Speaker 1: experienced astronauts with previous long duration space station experience. But
Speaker 1: right now NASA is dealing with a ripple effect with
Speaker 1: more astronauts than expected on the space station. More people
Speaker 1: means more consumables like food and clothing that are required.
Speaker 1: The space station has supported a large crew for short
Speaker 1: periods in the past, but with nine crew members already
Speaker 1: on board, the systems have to work harder to purify,
Speaker 1: recycle drinking water, generate oxygen, and remove carbon dioxide from
Speaker 1: their atmosphere. Wilmore and Williams are also consuming food, and
Speaker 1: they did derive with the clothes and other personal supplies
Speaker 1: they needed for an eighth month's stay, so NASA has
Speaker 1: already started increasing those deliveries on cargo ships.
Speaker 2: It's understood that.
Speaker 1: Human spaceflight is excruciatingly hard and relentlessly, unforgiving. A million
Speaker 1: things must go right to have a successful mission. It's
Speaker 1: impossible to fully understand the performance of systems in microgravity
Speaker 1: environments until they are tested in space. NASA has had
Speaker 1: its numerous failures and near misses in the quest to
Speaker 1: put Americans on the Moon. They lost the Apollo one
Speaker 1: crew and a fire during a pre flight test. They
Speaker 1: launched the first Space Shuttle in nineteen eighty one and
Speaker 1: dealt with problems throughout that programme's thirty year life, including
Speaker 1: the terrible losses of Challenger and Columbia. After having no
Speaker 1: other US options for over thirty years, three different human
Speaker 1: spacecraft programs are now underway. In addition to the SpaceX crew,
Speaker 1: Dragon and Boeing Star Owner NASA's oryon spacecraft for the
Speaker 1: Artemis two mission is planned to fly four astronauts around
Speaker 1: the Moon in the next couple of years. These programs
Speaker 1: have had setbacks and bumps along the way, and there
Speaker 1: will be more. But there is excitement in the air.
Speaker 1: There hasn't been this kind of excitement since Apollo put
Speaker 1: men on the moon. You're listening to a slightly Day
Speaker 1: the podcast, now moving on to the big story this
Speaker 1: week which is of course SpaceX Polarist Dawn mission, which
Speaker 1: made history when the crew conducted the first spacewalk by
Speaker 1: non government astronauts, and it's splashed down off the coast
Speaker 1: of Florida early on Sunday. It's landed in the ocean,
Speaker 1: and a webcast of the splashdown showed with a recovery
Speaker 1: team deploying in the pre dawn darkness to retrieve the
Speaker 1: capsule and crew. Form member team led by fintech billionaire
Speaker 1: Jared Isaacman, launched Tuesday from Kennedy Space Center, quickly journeying
Speaker 1: deeper into the Cosmos than any humans in the past
Speaker 1: half century. As they ventured into the dangerous Van Allen
Speaker 1: radiation belt. They reached a peak altitude of eight hundred
Speaker 1: and seventy miles that's fourteen hundred kilometers for the rest
Speaker 1: of US, more than three times higher than the International
Speaker 1: Space Station and the furthest humans had ever traveled from
Speaker 1: Earth since the Apollo missions. Then, on Thursday, with their
Speaker 1: Dragon spacecrafts or but brought down to four hundred and
Speaker 1: thirty four miles, Isaacman swung open the hatch and climbed
Speaker 1: out into the void. Gripping a structure called Skywalker. Of course,
Speaker 1: as the breathtaking view of Earth unfolded before him, SpaceX
Speaker 1: back home. We have a lot of work to do,
Speaker 1: but from here Earthshore looks like a perfect world, he
Speaker 1: told mission control in Hawthorne, California, where teams erupted into applause.
Speaker 1: He went back inside after a few minutes and was
Speaker 1: replaced by second astronaut, space EX engineer Sarah Gillis, who,
Speaker 1: like Isaacman, performed a series of mobility tests on SpaceX's
Speaker 1: sleek next generation suits, and I reckon those suits look fantastic.
Speaker 1: Since Dragon doesn't have an airlock, the entire crew were
Speaker 1: exposed to the vacuum of space. Mission pilot Scott Petit
Speaker 1: and SpaceX engineer Ana Menon remained strapped in throughout as
Speaker 1: they monitored vital support systems. I know what I would
Speaker 1: have been doing right then. It marked a giant leap
Speaker 1: forward for the commercial space industry and NASA Chief Bill Nelson,
Speaker 1: as well as another triumphant achievement for space X. Though
Speaker 1: the company was only founded in two thousand and two,
Speaker 1: it has outpaced its legacy competitors thanks to in large
Speaker 1: part to founder elon Musk's vast Fortune and Z to
Speaker 1: begin colonizing Mars. Since completing their extravehcular activity, the crew
Speaker 1: have continued to carry out roughly forty science experiments, for
Speaker 1: example inserting endoscopic cameras through their noses and into their
Speaker 1: throats to image their airways and better understand the impact
Speaker 1: of long duration space missions on human health fantastic. They
Speaker 1: also demonstrated connectivity with SpaceX's Starling Internet satellite constellation by
Speaker 1: sending back to ground control a high resolution video of
Speaker 1: Gillis playing raised theme by Star Wars composer John Williams
Speaker 1: on the violin. Polaris Dawn is the first of three
Speaker 1: missions under the Polaris program, a collaboration between Isaacman and SpaceX.
Speaker 1: Financial terms of the partnership remained under wraps, but Isaacman is,
Speaker 1: the forty one year old founder and CEO of Shift
Speaker 1: Fur Payments, reportedly poured two hundred million of his own
Speaker 1: money into lending the twenty twenty one all civilian space
Speaker 1: inspiration for orbital mission. The final Polaris mission aims to
Speaker 1: be the first crude flight of SpaceX's Starship, a prototype
Speaker 1: next generation rocket that is key to Musks Interplanetary Ambitions podcast. Okay,
Speaker 1: so at the top of the episode you heard Hally
Speaker 1: and I talking about David Bowie and the fabulous spiders
Speaker 1: from Mars.
Speaker 2: Well, so what's it all about.
Speaker 1: Scientists have recreated a geologic feature found on Mars, and
Speaker 1: it was difficult to do. Since discovering them in two
Speaker 1: thousand and three via images from orbiters, scientists have marveled
Speaker 1: at the spider like shapes sprawled was going to say
Speaker 1: crawling sprawled across the southern hemisphere of Mars. No one's
Speaker 1: entirely sure how these geologic features were created. Each branch
Speaker 1: formation can stretch more than half a mile or a
Speaker 1: kilometer from end to end and include hundreds of spindly legs,
Speaker 1: called a rakniform terrain. These features are often found in clusters,
Speaker 1: giving the surface a wrinkled appearance. The leading theory is
Speaker 1: that the spiders are created by processes involving carbon dioxide ice,
Speaker 1: which doesn't occur naturally on Earth. Thanks to experiments detailed
Speaker 1: in a new paper published in the Planetary Science Journal,
Speaker 1: scientists have for the first time recreated those formation processes
Speaker 1: in simulated Martian temperatures and air pressure. The spiders are strange,
Speaker 1: beautiful geological features in their own rights, said Lauren McEwan
Speaker 1: of NASA's Jet Propulsion Laboratory in southern California. These experiments,
Speaker 1: she says, will help us tune our models for how
Speaker 1: they form. The study confirms several formation processes described by
Speaker 1: what is called the Kaifer model. Sunlight heats the soil
Speaker 1: when it shines through transparent slabs of carbon dioxide ice
Speaker 1: that build up on the Martian surface each winter. Being
Speaker 1: darker than the ice above it, the soil absorbs the
Speaker 1: heat and causes the ice as close ice closest to
Speaker 1: it to turn directly into carbon dioxide gas without turning
Speaker 1: liquid first, in a process called sublimation, the same process
Speaker 1: that sends clouds of smoke billowing up from dry ice.
Speaker 1: As the gas builds up in pressure, the Martian ice cracks,
Speaker 1: allowing the gas to escape, and as it seeps upwards,
Speaker 1: the gas takes with it a stream of dark dust
Speaker 1: and sand from the soil that lands on the surface
Speaker 1: of the ice. When winter turns to spring, the remaining
Speaker 1: ice sublimates. According to the theory, the spider like scars
Speaker 1: from those small eruptions are what's left behind Fourmercu and
Speaker 1: n her coauthor's the hardest part of conducting these experiments
Speaker 1: was recreating the conditions found on the Martian polar surface,
Speaker 1: extremely low air pressure and temperatures as low as minus
Speaker 1: three hundred and one degrees fahrenheit that's minus one hundred
Speaker 1: and eighty five degrees celsius. To do that, mcuan used
Speaker 1: liquid nitrogen cooled test chamber at JPL, a dirty under
Speaker 1: vacuum simulation test bed for icy environments. And they call
Speaker 1: that dusty. They love their achromans. I love dusty. She
Speaker 1: says it's historic, McEwan said, noting that the wine barreled
Speaker 1: sized chamber was used as a test prototype for a
Speaker 1: rasping tool designed for NASA's Mars Phoenix lander. The tool
Speaker 1: was used to break water ice, which the spacecraft scooped
Speaker 1: up and analyzed near the planet planet's north pole.
Speaker 2: For this experiment, the.
Speaker 1: Researchers chilled Martian soil simulant in a container submerged with
Speaker 1: liquid nitrogen bath. They placed it in the dusty chamber,
Speaker 1: where the air pressure was reduced to be similar to
Speaker 1: that of Mars's southern hemisphere. Carbadoxide gas then flowed into
Speaker 1: the chamber and condensed from gas to ice over the
Speaker 1: course of three to five hours. It took many tries
Speaker 1: before mcurn just found the right conditions for the ice
Speaker 1: to become thick and translucent enough for the experiments to work.
Speaker 1: Once they got the ice with the right properties, they
Speaker 1: placed a heater inside the chamber below the simulant to
Speaker 1: warm it up and crack the ice. A Curn was
Speaker 1: ecstatic when she finally saw a plume of carbon dioxide
Speaker 1: gas a wrapting errapting from within the powdery simulant. Dark
Speaker 1: plumes opened holes in the simulant as they streamed out,
Speaker 1: spewing simulant for as long as ten minutes before all
Speaker 1: the pressurized gas was expelled. There are still many questions
Speaker 1: about the spiders that Carbi answered in a lab Why
Speaker 1: have they formed in some places but not others Since
Speaker 1: they appear to result from seasonal changes that are still occurring.
Speaker 1: Why don't they seem to be growing in number or
Speaker 1: in size over time. It's possible that they may be
Speaker 1: left over from long ago when the climate was different
Speaker 1: on Mars and could provide answers to the planet's passed
Speaker 1: but for the time being, lab experiments will be as
Speaker 1: close to the spiders as scientists can get both the
Speaker 1: curiosity and perseverance. Rovers are exploring the Red planet far
Speaker 1: from the Southern Hemisphere, which is where these formations actually
Speaker 1: appear and where no spacecraft has ever landed. And just
Speaker 1: to give you an idea how tough things are up there,
Speaker 1: the Phoenix mission, which landed in the Northern Hemisphere, lasted
Speaker 1: only a few months before succumbing to the intense polar
Speaker 1: cold and limited sunlight.
Speaker 2: Cool.
Speaker 1: I got cold just reading that story. Holy cow, And
Speaker 1: that's all she wrote. Folks, thanks for sticking around with
Speaker 1: us today. I really hope you enjoyed those tales of
Speaker 1: space science and astronomy.
Speaker 4: And I hope you'll join us again next week for
Speaker 4: more Astronomy Daily. But don't forget, Charlie and Anna will
Speaker 4: be bringing the show to you during the week, so
Speaker 4: don't miss all the news from the Astronomy Daily newsletter.
Speaker 2: Oh excellent, Ally a second, that emotion nice, So we'll
Speaker 2: see you all next week.
Speaker 4: Bye.
Speaker 2: Your whole silly bla gets are.
Speaker 3: Jamming good with Weed and Ginner the spiders from Mars.
Speaker 1: You pleaded left hand.
Speaker 3: And made it too far became a special man. Then
Speaker 3: we were Ziggie's boun Ziggy really sang, screwed.
Speaker 2: Up bys and screwed down handle lack. Some cat from Japan.
Speaker 3: You can lock him by smiler, leave him to hand.
Speaker 2: Came on some loaded man.
Speaker 4: Well, Hannah's words, totally groovy
