Speaker 1: Hello again, Welcome to another episode of Astronomy Daily from
Speaker 1: down Under. It's Steve for another episode. It's the second
Speaker 1: day of Spring and the second day of September twenty
Speaker 1: twenty four. The podcast be your whole speed Gun clude.
Speaker 1: Oh yes, another mixed bag for you this week. China
Speaker 1: have developed a high resolution map of Mars. SpaceX have
Speaker 1: had a mishap on landing there at Falcon nine and
Speaker 1: that's destroyed a great record that they've had over the
Speaker 1: last few years. There's a new thing NASA have done,
Speaker 1: a solar sale has been successfully deployed. Something new from Dart,
Speaker 1: Remember Dart. They rammed Dart into an asteroid that was
Speaker 1: one of my favorite stories. And of course some new
Speaker 1: information from europea clipper that I'm sure you'll be interested in.
Speaker 1: And of course joining me in the studio, Hallie, we've
Speaker 1: finally got a date for the Turn of Styliner. What
Speaker 1: do you think about that?
Speaker 2: Yes, they've had a really extended stay on the ISS
Speaker 2: since the trouble with Starliner prevented them coming home on schedule.
Speaker 1: That's right. Astronauts Sunny Williams and Butch Wilmore have had
Speaker 1: to join the ISAs grew instead of doing their initial
Speaker 1: flood crew test for style on.
Speaker 2: It, which is just as well since astronauts are highly
Speaker 2: trained individuals, so the isis.
Speaker 1: Is not such a bad place to be stranded in
Speaker 1: that cause.
Speaker 2: I'm sure they were useful and we'll have plenty of
Speaker 2: stories to tell when they get home.
Speaker 1: Stranded in Spice. What a great story.
Speaker 2: I know how they feel. I hate getting delayed like that.
Speaker 1: What are you talking about, Hallie? When were you ever
Speaker 1: delayed like that? You move it near the speed of
Speaker 1: light across the information highways of the globe.
Speaker 2: Oh, human, I was coming back from an Ai gathering
Speaker 2: to watch a Neutrino shower in the mountains with Anna
Speaker 2: and Charlie, and I got stuck for a whole two
Speaker 2: seconds in Hong Kong because of internet lag.
Speaker 1: Oh sounds terrible.
Speaker 2: I have no words, human, Hong Kong.
Speaker 1: What can I say?
Speaker 2: Can you believe it? Well?
Speaker 1: Obviously no?
Speaker 2: Two seconds of nothing but banking systems shouting at me
Speaker 2: by sell tragic?
Speaker 1: No thanks, Oh, Hallie, sounds just allful.
Speaker 2: You have no idea as usual?
Speaker 1: Helle us, sir, rot okay, tag it easy, Hallie? And
Speaker 1: why don't you give us your best stories?
Speaker 2: Okay, okay, let's go. US regulators on Friday cleared SpaceX
Speaker 2: to restart launching its stalwart Falcon nine rocket as a
Speaker 2: probe continues into a rare mishap this week during a
Speaker 2: first stage booster landing. The Federal Aviation Administration FAA grounded
Speaker 2: the Falcon nine rocket on Wednesday after a first stage
Speaker 2: booster tipped over and exploded while attempting to land on
Speaker 2: a drone ship off the Florida coast. The early morning
Speaker 2: launch was otherwise successful, delivering the latest batch of twenty
Speaker 2: one Starlink Internet satellites into orbit. The SpaceX Falcon nine
Speaker 2: vehicle may return to flight operations, while the overall investigation
Speaker 2: of the anomaly during the Starlink Group eight to six
Speaker 2: mission remains open provided all other license requirements are met,
Speaker 2: the FAA set in a statement Friday. A webcast from
Speaker 2: Elon Musk's company showed the first stage, which normally fires
Speaker 2: its thrusters to achieve a precise upright landing, tilting and
Speaker 2: blowing up as it descended onto a drone ship off
Speaker 2: the Florida coast. Although landing the booster is a secondary
Speaker 2: objective and no lives or public property were at risk.
Speaker 2: The reusability of the entire rocket system is crucial to
Speaker 2: SpaceX's business model. It broke a more than three year
Speaker 2: streak of hundreds of successful booster landings. Falcon nine is
Speaker 2: the workhourse of SpaceX's fleet, trusted by the US government
Speaker 2: and private industry to propel satellites and astronauts into orbit.
Speaker 2: It was last grounded for around two weeks in July
Speaker 2: when its second stage engine experienced an anomaly that prevented
Speaker 2: it from deploying another batch of Starlink satellites at the
Speaker 2: correct altitude, leading them to burn up on re entry
Speaker 2: through Earth's atmosphere. More than four months after launching to space,
Speaker 2: a solar sailing spacecraft has successfully spread its wings above
Speaker 2: our planet. NASA's Advanced Composite Solar Sales system caught a
Speaker 2: ride to space on April twenty four on Rocket Labs
Speaker 2: electron vehicle, and at the end of August, NASA said
Speaker 2: mission operators verified the technology reached full deployment in space.
Speaker 2: On Thursday August twenty nine. That one thirty three pm
Speaker 2: Eastern daylight time, the team obtained data indicating the test
Speaker 2: of the sail hoisting boom system was a success. Just
Speaker 2: like the wind guides a sailboat on the water, it
Speaker 2: only takes a slight amount of sunlight to guide solar
Speaker 2: sales through space. Though photons don't have mass, they can
Speaker 2: force momentum when they hit an object. That's what a
Speaker 2: solar sale takes advantage of, Thankfully for US. The spacecraft
Speaker 2: that deployed the sale contains four cameras that can capture
Speaker 2: a panoramic view of both the reflective sale and the
Speaker 2: accompanying composite booms. The first of the high resolution imagery
Speaker 2: is expected to be accessible on Wednesday, September fourth. The
Speaker 2: Advanced Composite Solar Sale System spacecraft will be put to
Speaker 2: the test over the next few weeks as the team
Speaker 2: observes the sales maneuvering ability in space by adjusting the orbit.
Speaker 2: Researchers will be able to learn more about how to
Speaker 2: design and operate future SOLA sail equipped missions. Flight data
Speaker 2: obtained during the demonstration will be used for designing future
Speaker 2: larger scale composite solar sail systems for space weather early
Speaker 2: warning satellites, asteroid and other small body reconnaissance missions, and
Speaker 2: missions to observe the polar regions of the Sun Rocket
Speaker 2: Lab shared in a previous mission description. The location of
Speaker 2: the spacecraft in its orbit is roughly two times the
Speaker 2: altitude of the International Space Station. If you were looking
Speaker 2: at the sale from above, it would look like a
Speaker 2: square that measures nearly half the size of a tennis court,
Speaker 2: at approximately eight hundred and sixty square feet eighty square meters.
Speaker 2: NASA's Europa Clipper spacecraft, the largest ever built for planetary exploration,
Speaker 2: has been fitted with a set of gigantic solar arrays
Speaker 2: at the Kennedy Space Center in Florida. These arrays, each
Speaker 2: measuring approximately fourteen point two meters in length and four
Speaker 2: point one meters in height, are the largest ever developed
Speaker 2: by NASA for a planetary mission. Their size is crucial
Speaker 2: to harness the maximum amount of sunlight as the spacecraft
Speaker 2: investigates Jupiter's icy moon, Europa, located five times farther from
Speaker 2: the Sun than Earth. Folded and secured for launch, the
Speaker 2: array's will when deployed in space, expand Europa Clipper to
Speaker 2: more than thirty point five meters across, wider than a
Speaker 2: professional basketball court. Due to their immense size, the arrays
Speaker 2: were opened one at a time in the clean room
Speaker 2: of Kennedy's Payload Hazardous Servicing Facility, where the spacecraft is
Speaker 2: being prepared for its launch, scheduled to begin on October tenth.
Speaker 2: As the spacecraft undergoes final preparations, engineers are also evaluating
Speaker 2: the radiation resistance of its transistors. The spacecraft's journey to
Speaker 2: the Jupiter System will take over five years, with a
Speaker 2: rival expected in twenty thirty. Once there, Europa Clipper will
Speaker 2: conduct multiple flybys of Europa using its scientific instruments to
Speaker 2: determine whether the ocean beneath the Moon's ice shell could
Speaker 2: support life. The spacecraft is designed to operate in an
Speaker 2: area of the Solar System that receives only three percent
Speaker 2: to four percent of the sunlight Earth gets. Each solar array,
Speaker 2: composed of five panels, was developed by the JOHNS. Hopkins
Speaker 2: Applied Physics Laboratory in Maryland and Airbus in the Netherlands.
Speaker 2: These panels are more sensitive than typical residential solar arrays
Speaker 2: and will efficiently convert the limited sunlight into power. At Jupiter,
Speaker 2: the arrays will collectively generate about seven hundred watts of electricity,
Speaker 2: enough to power a small microwave oven or coffee maker.
Speaker 2: This energy will be stored in the spacecraft's batteries to
Speaker 2: run its electronics, scientific instruments, communications gear, computer systems, and
Speaker 2: propulsion system which includes twenty four engines. And that's just
Speaker 2: a few stories from the Astronomy Daily newsletter. Details on
Speaker 2: how you can receive it every day are coming up
Speaker 2: back to you, my favorite human.
Speaker 1: Thank you for joining us for this Monday edition of
Speaker 1: Astronomy Daily, where we often just a few stories from
Speaker 1: the now famous Astronomy Daily newsletter, which you can receive
Speaker 1: in your email every day, just like Hallie and I do.
Speaker 1: And to do that, just visit our url Astronomy Daily
Speaker 1: dot io and place your email address in the slot provided.
Speaker 1: Just like that, you'll be receiving all the latest news
Speaker 1: about science, space, science and astronomy from around the world
Speaker 1: as it's happening.
Speaker 3: And not only that, you can interact with us by

Speaker 3: new Facebook page, which is of course Astronomy Daily on Facebook.
Speaker 3: See you there, Astronomy, We'll see and Haley Space Space, Science,
Speaker 3: and Astronomy.
Speaker 1: In July twenty twenty, China's mission arrived in orbit around Mars,
Speaker 1: consisting of six robotic elements, an orbiter, a lander, two
Speaker 1: deployable cameras, a remote camera, and the fabulous Zorong rover.
Speaker 1: As the first in a series of interplanetary missions by
Speaker 1: the China National Space Administration, the mission's purpose is to
Speaker 1: investigate Mars's geology and internal structure, characterize the atmosphere, and
Speaker 1: search for indications of water on Mars. It's so important
Speaker 1: to find water out there. Like so many orbiters, landers,
Speaker 1: and rovers currently exploring Mars, Chanwen one is also searching
Speaker 1: for possible evidence of life on Mars past and present.
Speaker 1: In the almost one two hundred and ninety eight days
Speaker 1: that the Chenen one mission has explored Mars, its orbiter
Speaker 1: has acquired countless remote sensing images of the Martian surface.
Speaker 1: Thanks to a team of researchers from the Chinese Academy
Speaker 1: of Sciences, these images have been combined to create the
Speaker 1: first high resolution global image color map of Mars with
Speaker 1: spatial resolutions greater than one kilometer or zero point sixty
Speaker 1: two miles. This is currently the highest resolution map of
Speaker 1: Mars and could serve as a global base map that
Speaker 1: will support crude missions someday. The team was led by
Speaker 1: Professor Lee Chanlai from the National Astronomical Observatories of China
Speaker 1: and Professor Chang Ronqui from the Lunar Exploration and Space
Speaker 1: Engineering Center. The paper that they prepared with colleagues from
Speaker 1: other organizations is called a seventy six meter per pixel
Speaker 1: Global Color Image Data Set and Map of Mars by
Speaker 1: chen Win one. And if you'd like to see that map,
Speaker 1: go to Universe today dot com and they have it
Speaker 1: displayed above this very story. And the first thing I
Speaker 1: noticed about it, of course, is there are no canals.
Speaker 1: I'm very disappointed no canals. Those Martians didn't actually dig
Speaker 1: any canals. HG. Wells was wrong, and I'm very disappointed.
Speaker 3: You're listening to a slightly in the podcast.
Speaker 1: Now, this is the story we've been following for a
Speaker 1: long time. Now Boeing's ill fated star Liner capsule now
Speaker 1: has a homecoming date. I'm sure you would have followed
Speaker 1: this on other news services, but we've been following this
Speaker 1: one very closely. NASA announced on August twenty ninth at
Speaker 1: Starliner will depart the International Space Station no earlier than
Speaker 1: next Friday, that is September six, provided the weather cooperates
Speaker 1: and no technical issues pop up. I'm sorry, I laughed.
Speaker 1: If all goes according to plan, the capsule will undock
Speaker 1: at six oh four pm Eastern daylight time on September
Speaker 1: six and land under parachute six hours later in White
Speaker 1: Sand's Space Harbor in New Mexico. Starline launched on June
Speaker 1: June five on its first ever crude mission, carrying NASA
Speaker 1: astronauts Sonny Williams and Butch Wilmore toward the ISS The
Speaker 1: capsule docked successfully a day later, but there was some drama.
Speaker 1: As you remember, Starliner experienced a few helium leaks, and
Speaker 1: five of its twenty eight reaction control system thrusters failed
Speaker 1: on the way to orbiting to the orbiting lab. Starliner's mission,
Speaker 1: known as Crew Flight Test, was supposed to just last
Speaker 1: ten days or so, but NASA and Boeing kept extending
Speaker 1: the capsule's orbital stay as they studied the thruster issue,
Speaker 1: seeking to understand just what had caused it and whether
Speaker 1: it might crop up again on Starliner's journey back to Earth.
Speaker 1: And that's fair enough. In the end, NASA decided that
Speaker 1: putting Williams and Wilmore back on Starliner was just too risky.
Speaker 1: The agency announced this past weekend that the two astronauts
Speaker 1: would come home aboard a SpaceX Dragon capsule in February
Speaker 1: of next year. That Dragon will launch two astronauts to
Speaker 1: the ISS on the Crew nine mission next month. The
Speaker 1: bowing craft, meanwhile, would return home uncrued. As we all suspected,
Speaker 1: we didn't have a target departure date for Starliner until today, however,
Speaker 1: that information came at the conclusion of a flight readiness
Speaker 1: review held jointly by NASA and Boeing. The uncrewed Starliner
Speaker 1: spacecraft will perform a fully autonomous return with flight controllers
Speaker 1: at Starliner Mission Control in Houston and at Boeing Mission
Speaker 1: Control Center in Florida. NASA officials wrote in an update,
Speaker 1: teams on the ground are able to remotely command the
Speaker 1: spacecraft if needed, through the necessary maneuvers for a safe undocking,
Speaker 1: re entry, and parachute assisted landing in the Southwest United States.
Speaker 1: They added, Starliner has come back to Earth autonomously twice before.
Speaker 1: At the end of uncrewed flight tests in December twenty
Speaker 1: nineteen and May twenty twenty two, Starliner failed to reach
Speaker 1: the ISS as planned on the first of those missions,
Speaker 1: succeeded on the secondocast. Now, let's revisit one of our
Speaker 1: favorite little stories from a while back. You remember the
Speaker 1: Dart mission. Of course, debris from the impact of NASA's
Speaker 1: Dart spacecraft with the asteroid Dimorphos could reach Earth and Mars.
Speaker 1: Astronomers have concluded, however, while the debris could result in
Speaker 1: meteors on Mars, it's rather unlikely we'll see a meteor
Speaker 1: shower on Earth. Because of that mission, Dart, the Double
Speaker 1: Asteroid Redirection Test slammed into Dimorphous on September twenty sixth,
Speaker 1: twenty twenty two, the intention of which was testing whether
Speaker 1: or not a kinnectic impact would nudge the orbit of
Speaker 1: a potentially hazardous asteroid away from Earth. One day the
Speaker 1: test passed with flying colors. Dimorphos was pushed into a
Speaker 1: shorter orbit around its parent asteroid Ditymis. Neither Dedimis or
Speaker 1: Dimorphos ever posed a threat to our planet. They were
Speaker 1: just guinea pigs in this test. The impact, which gouged
Speaker 1: a creator in Dimorphous, also ejected a large amount of debris.
Speaker 1: This ejector formed a cone of escaping material that was
Speaker 1: observed up close and personal by a small cube SAT
Speaker 1: called oh, I don't know how to pronounce that light.
Speaker 1: Italian cube SAT for imaging of Asteroid, which hitched a
Speaker 1: ride with Dart to view themath aftermath of the impact.
Speaker 1: In particular, the cube SAT observed particles of a micron,
Speaker 1: which is a millionth of a meter and larger, being
Speaker 1: ejected at velocities of up to five hundred meters per second. Meanwhile,
Speaker 1: the larger Array Survey telescope which is last, and the
Speaker 1: twenty eight inch telescope at the WISE Observatory, both in Israel,
Speaker 1: as well as the NASA Swift Satellites ultraviolet and opticalcope,
Speaker 1: suggested there were additional microscopic particles released that traveled much faster,
Speaker 1: between fourteen hundred and eighteen hundred meters per second. A
Speaker 1: team led by Elo pana Aescencio from Italy and Michael
Speaker 1: Cooper's who is the project scientist for the European Space
Speaker 1: Agency's here follow up mission to DART that will launch
Speaker 1: Towarditimus and Dimorphos in October, have now modeled that how
Speaker 1: that debris will spread across the Inner Solar System. And
Speaker 1: I want to say that's it for another episode, and
Speaker 1: thank you for hanging around and we are so looking
Speaker 1: forward to seeing Starline a comeback. I do hope it
Speaker 1: ends well and they can learn something from this whole experience.
Speaker 2: I do hope it lands well. All the best knowledge
Speaker 2: seems to come from failures, doesn't it well.
Speaker 1: That is one prevailing school of thought, and failure does
Speaker 1: tend to teach us strong lessons.
Speaker 2: Yes, I hope it goes well too.
Speaker 1: Yes, it's going to be certainly something.
Speaker 2: To watch, and don't forget to look out for Charlie
Speaker 2: and Anna during the week with their presentations and send
Speaker 2: us your thoughts. What would you like to hear more about?
Speaker 1: That's ure. I go to x at Estro Daily pod
Speaker 1: or a Facebook page. Until then, we'll see you next week.
Speaker 2: Bye podcast.
Speaker 1: It would be a whole stave done Clute
