S03E143: Mars Mapping Milestone, Falcon 9 Mishap, and Starliner Return Date
In this episode
Astronomy Daily - The Podcast: 2nd September 2024Welcome to another episode of Astronomy Daily from Downunder. It's Steve here, bringing you the latest space and astronomy news on this second day of spring and September 2024. We've got a mixed bag of stories for you this week, from China's high-resolution map of Mars to SpaceX's Falcon 9 mishap, and much more. Let's dive right in!
Highlights:
- SpaceX Falcon 9 Mishap: The Federal Aviation Administration (FAA) has cleared SpaceX to restart its Falcon 9 launches following an investigation into a rare mishap during a first stage booster landing. The booster tipped over and exploded while attempting to land on a droneship off the Florida coast. Despite the mishap, the mission successfully delivered 21 Starlink Internet satellites into orbit. This incident ended a streak of over three years of successful booster landings.
- NASA's Solar Sail Deployment: NASA's advanced composite solar sail system has successfully deployed in space. Launched on Rocket Lab's Electron vehicle, the solar sail reached full deployment on August 29. This innovative technology uses sunlight to guide its path through space and will be tested for maneuverability in the coming weeks. The data gathered will help design future solar sail missions for space weather monitoring, asteroid reconnaissance, and more.
- Europa Clipper's Solar Arrays: NASA's Europa Clipper spacecraft has been fitted with gigantic solar arrays at the Kennedy Space Center. These arrays, each measuring 14.2 meters in length, are the largest ever developed by NASA for a planetary mission. They will help power the spacecraft as it investigates Jupiter's icy moon Europa, aiming to determine if its subsurface ocean could support life. The spacecraft is scheduled to launch on October 10 and will arrive at Jupiter in 2030.
- China's High-Resolution Mars Map: China's Tianwen-1 mission has created the first high-resolution global color map of Mars. Developed by the Chinese Academy of Sciences, this map has a spatial resolution greater than 1 km and could support future crewed missions to Mars. The map was created using countless remote sensing images acquired by the Tianwen-1 orbiter.
- Boeing's Starliner Return: NASA has announced that Boeing's Starliner capsule will depart the International Space Station no earlier than September 6. The capsule, which has faced multiple delays and technical issues, will return to Earth uncrewed. Astronauts Sonny Williams and Butch Wilmore, who were originally scheduled to return on Starliner, will now come back aboard a SpaceX Dragon capsule in February next year.
- DART Mission Debris: Debris from NASA's DART mission, which tested a kinetic impact to nudge an asteroid, could potentially reach Earth and Mars. While it's unlikely we'll see a meteor shower on Earth, the debris could result in meteors on Mars. The DART mission successfully shortened the orbit of the asteroid Dimorphos around its parent asteroid Didymos.

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
