Ep. 16 Voyager Golden Record - HD and the Void

Full disclosure: this is a kissing story. A kissing story about the ultimate mixtape and alien communication plan, sent out in 1977 and now in interstellar space. Hear about the Voyager Golden Record and the people who put it together as a compila...

The process of making an audio and visual compilation to explain Earth and humanity to an alien species is an incredible undertaking, and Carl Sagan undertook it in 1977. The resulting record from his little team was sent out with the Voyager 1 and 2 probes and is now in interstellar space, but there was also a more personal result of this project. Learn about Sagan and his third wife’s meet-cute and also hear what is actually out there in the stars, conveying the best humanity had to offer in the 70s. 

Below the cut are my sources, music credits, a vocab list, and the transcript of this episode. Vote on what you think I should research next by messaging me here, tweeting at me at @HDandtheVoid, or asking me to my face if you know me in real life. And please subscribe to the podcast on iTunes, rate it and maybe review it, and tell friends if you think they’d like to listen!

(My thoughts on the next episode are space race history, the transit of Venus, Edmond Halley, or Dark Sky Preserves. Next episode will be up on December 4th.)

Margaret Hamilton is a computer scientist and mathematician. She was the lead software engineer for Project Apollo.  Her work prevented an abort of the Apollo 11 moon landing. She’s also credited for coining the term “software engineer." 

Solar System: Things to Know This Week

Like sailors of old, the Cassini mission team fondly thinks of the spacecraft as “she."  On April 22, she begins her Grand Finale, a spectacular end game—22 daring dives between the planet’s atmosphere and innermost rings. Here are 10 things to know about her Grand Finale.

1. She’s Broadcasting Live This Week

On Tuesday, April 4 at 3 p.m. EDT  (noon PDT), At Jet Propulsion Laboratory, the Cassini team host a news briefing to discuss the mission’s Grand Finale.

Tune in Tuesday: youtube.com/nasajpl/live

2. She’s Powered in Part By … Titan

Cassini left Earth with less than 1/30th of the propellant needed to power all her adventures at Saturn. The navigation team used the gravity of Saturn’s giant moon Titan to change course and extend the spacecraft’s exploration of Saturn. Titan also provides the gravity assist to push Cassini into its final orbits.

More on Cassini’s navigation: saturn.jpl.nasa.gov/mission/spacecraft/navigation/

3. She’s a Robot

Cassini is an orbiter that was named for 18th century astronomer Giovanni Domenico Cassini. She was designed to be captured by Saturn’s gravity and then explore it in detail with a suite of 12 powerful science instruments.

More on the Spacecraft: saturn.jpl.nasa.gov/mission/spacecraft/cassini-orbiter/

4. She Brought a Friend to Saturn

Cassini carried the European Space Agency’s Huygens Probe, which in 2005 descended through Titan’s thick, perpetual clouds and made the most distant landing to date in our solar system.

More on Huygens: saturn.jpl.nasa.gov/mission/spacecraft/huygens-probe/

5. She’s a Great Photographer

Your mobile phone likely captures dozens of megapixels in images. Cassini, using 1990s technology closer to one megapixel cameras, has returned some of the most stunning images in the history of solar system exploration.

Cassini Hall of Fame Images: go.nasa.gov/2oec6H2 More on Cassini’s Cameras: saturn.jpl.nasa.gov/imaging-science-subsystem/

6. She’s an Inspiration

Those great images have inspired artist’s and amateur image processors to create truly fantastic imagery inspired by the beauty of Saturn. Feeling inspired? There’s still time to share your Cassini-inspired art with us.

Cassini Inspires Campaign: saturn.jpl.nasa.gov/mission/cassiniinspires/

7. She’s Got a Long History

Two decades is a long time to live in the harsh environment of outer space (respect to the fast-approaching 40-year-old twin Voyager spacecraft). Launched in 1997, Cassini logged a lot of milestones over the years.

Explore the Cassini Timeline: saturn.jpl.nasa.gov/the-journey/timeline/

8. She Keeps a Diary

And, you can read it. Week after week going back to 1997, Cassini’s adventures, discoveries and status have been chronicled in the mission’s weekly significant events report.

Read It: https://saturn.jpl.nasa.gov/news/?topic=121

9. She’s Got a Fancy New App

Cassini was the prototype for NASA’s Eyes on the Solar System 3-D visualization software, so it’s fitting the latest Cassini module in the free, downloadable software is the most detailed, elaborate visualization of any mission to date.

10. She’s Going Out in a Blaze of Glory

In addition to all the new information from 22 orbits in unexplored space, Cassini’s engineers reprogrammed the spacecraft to send back details about Saturn’s atmosphere to the very last second before the giant planet swallows her up on Sept. 15, 2017.

The Cassini probe took a picture of Saturn that includes Earth in it!

Cassini has actually taken a ton of cool photos of Saturn if you want to check those out in the wake of last week’s planets podcast. 

This is so sweet! What a nice way to spend a Saturday night.

Make Sure You Observe the Moon on October 20

On Saturday, October 20, NASA will host the ninth annual International Observe the Moon Night. One day each year, everyone on Earth is invited to observe and learn about the Moon together, and to celebrate the cultural and personal connections we all have with our nearest celestial neighbor.

There are a number of ways to celebrate. You can attend an event, host your own, or just look up! Here are 10 of our favorite ways to observe the Moon:

1. Look up

Image credit: NASA’s Scientific Visualization Studio/Ernie Wright

The simplest way to observe the Moon is simply to look up. The Moon is the brightest object in our night sky, the second brightest in our daytime sky and can be seen from all around the world — from the remote and dark Atacama Desert in Chile to the brightly lit streets of Tokyo. On October 20, the near side of the Moon, or the side facing Earth, will be about 80 percent illuminated, rising in the early evening.

See the Moon phase on October 20 or any other day of the year!

2. Peer through a telescope or binoculars

With some magnification help, you will be able to focus in on specific features on the Moon, like the Sea of Tranquility or the bright Copernicus Crater. Download our Moon maps for some guided observing on Saturday.

3. Photograph the Moon

Image credit: NASA/GSFC/ASU

Our Lunar Reconnaissance Orbiter (LRO) has taken more than 20 million images of the Moon, mapping it in stunning detail. You can see featured, captioned images on LRO’s camera website, like the one of Montes Carpatus seen here. And, of course, you can take your own photos from Earth. Check out our tips on photographing the Moon!

4. Take a virtual field trip

Image credit: NASA/JPL-Caltech

Plan a lunar hike with Moontrek. Moontrek is an interactive Moon map made using NASA data from our lunar spacecraft. Fly anywhere you’d like on the Moon, calculate the distance or the elevation of a mountain to plan your lunar hike, or layer attributes of the lunar surface and temperature. If you have a virtual reality headset, you can experience Moontrek in 3D.

5. Touch the topography

Image credit: NASA GSFC/Jacob Richardson

Observe the Moon through touch! If you have access to a 3D printer, you can peruse our library of 3D models and lunar landscapes. This model of the Apollo 11 landing site created by NASA scientist Jacob Richardson, is derived from LRO’s topographic data. Near the center, you can actually feel a tiny dot where astronauts Neil Armstrong and Buzz Aldrin left the Lunar Descent Module.

6. Make Moon art

Image credit: LPI/Andy Shaner

Enjoy artwork of the Moon and create your own! For messy fun, lunar crater paintings demonstrate how the lunar surface changes due to consistent meteorite impacts.

7. Relax on your couch

Image credit: NASA’s Scientific Visualization Studio/Ernie Wright

There are many movies that feature our nearest neighbor, from A Voyage to the Moon by George Melies, to Apollo 13, to the newly released First Man. You can also spend your evening with our lunar playlist on YouTube or this video gallery, learning about the Moon’s role in eclipses, looking at the Moon phases from the far side, and seeing the latest science portrayed in super high resolution. You’ll impress all of your friends with your knowledge of supermoons.

8. Listen to the Moon

Video credit: NASA’s Scientific Visualization Studio/Ernie Wright

Make a playlist of Moon songs. For inspiration, check out this list of lunar tunes. We also recommend LRO’s official music video, The Moon and More, featuring Javier Colon, season 1 winner of NBC’s “The Voice.” Or you can just watch this video featuring “Clair de Lune,” by French composer Claude Debussy, over and over.

9. See the Moon through the eyes of a spacecraft

Image credit: NASA/GSFC/MIT

Visible light is just one tool that we use to explore our universe. Our spacecraft contain many different types of instruments to analyze the Moon’s composition and environment. Review the Moon’s gravity field with data from the GRAIL spacecraft or decipher the maze of this slope map from the laser altimeter onboard LRO. This collection from LRO features images of the Moon’s temperature and topography. You can learn more about our different missions to explore the Moon here.

10. Continue your observations throughout the year

Image credit: NASA’s Scientific Visualization Studio/Ernie Wright

An important part of observing the Moon is to see how it changes over time. International Observe the Moon Night is the perfect time to start a Moon journal. See how the shape of the Moon changes over the course of a month, and keep track of where and what time it rises and sets. Observe the Moon all year long with these tools and techniques!

However you choose to celebrate International Observe the Moon Night, we want to hear about it! Register your participation and share your experiences on social media with #ObserveTheMoon or on our Facebook page. Happy observing!

Ep. 19 Astronauts - Long-Term Space Living - HD and the Void

How to astronauts shower? How many astronauts are on the International Space Station right now? How do you pack enough food for them? What kind of comfortable housing options are available when orbiting Earth? What can you pack and not pack? All t...

I imagine most people wanted to be astronauts when they learned it was a job they could have - I certainly did! And then I thought about it and realized podcasting about outer space was much less scary and much more achievable than becoming an astronaut, with the bonus of not having to wonder how hard I’d panic in an enclosed-yet-surrounded-by-vastness space. There have been a lot of people braver than me who went to space, and some of them went to space on long-term missions lasting months or a year, living on the International Space Station (or the historical equivalent, depending on when in history this happened). Learn what resources are available to ISS astronauts, and what risks there are out there (apart from the obvious ones).

Sorry I missed last week, but it was New Year’s and I don’t feel very guilty. Get excited about more space podcasts in 2018, though! Below the cut are my sources, music credits, a vocab list, and the transcript of this episode. I bolded any videos or sources that I mentioned in the podcast, if you’re looking for those specifically. Go ahead and suggest what you think I should research next by messaging me here, tweeting at me at @HDandtheVoid, or asking me to my face if you know me. Please subscribe on iTunes, rate it and maybe review it, and tell friends if you think they’d like to hear it! 

(My thoughts on the next episode are more about astronauts, or I could go into the transit of Venus. I have a couple books about space I should really get into reading… The next episode will go up January 22nd.)

Glossary

free fall - the downward movement of an object that is due to the force of gravity alone.

gravity - the phenomenon which causes all things with mass to move towards each other. On the universal scale, this is caused by the warping of spacetime by objects with large mass, e.g. stars and planets, and is explained through Einstein’s theory of general relativity.

microgravity - the state of perpetual free fall in a gravity field.

orbit - the gravitationally curved trajectory of an object, e.g. the trajectory of a satellite around a planet.

Interview with astronaut Chris Hadfield via NPR (Oct 2013)

Col. Chris Hadfield: “The contrast of your body and your mind inside … essentially a one-person spaceship, which is your spacesuit, where you’re holding on for dear life to the shuttle or the station with one hand, and you are inexplicably in between what is just a pouring glory of the world roaring by, silently next to you — just the kaleidoscope of it, it takes up your whole mind. It’s like the most beautiful thing you’ve ever seen just screaming at you on the right side, and when you look left, it’s the whole bottomless black of the universe and it goes in all directions. It’s like a huge yawning endlessness on your left side and you’re in between those two things and trying to rationalize it to yourself and trying to get some work done.”
