Solar System: Things To Know This Week

Does an ecplispe cause any unusual effects on the Earth?

Yes, and this is one of the things we’re hoping to study more with this eclipse! If you are in totality, you’ll notice a significant temperature drop. We are also expecting to see changes in the Earth’s atmosphere and ionosphere. You can help us document these changes using the GLOBE Observer app https://www.globe.gov/globe-data/data-entry/globe-observer ! There are lots of great citizen science going on during this eclipse, and we’d love to have everyone here helping out! https://eclipse2017.nasa.gov/citizen-explorers

NASA Parachute Device Could Return Small Spacecraft from Deep Space Missions

ISS - International Space Station patch. March 7, 2017

After a two-month stay aboard the International Space Station, NASA’s Technology Educational Satellite (TechEdSat-5) that launched Dec. 9, 2016, was deployed on March 6, 2017 from the NanoRacks platform and into low-Earth orbit to demonstrate a critical technology that may allow safe return of science payloads to Earth from space. Orbiting about 250 miles above Earth, the Exo-Brake, a tension-based, flexible braking device resembling a cross-shaped parachute, opens from the rear of the small satellite to increase the drag. This de-orbit device tests a hybrid system of mechanical struts and flexible cord with a control system that warps the Exo-Brake. This allows engineers to guide the spacecraft to a desired entry point without the use of fuel, enabling accurate landing for future payload return missions.

Small Satellite With Exo-Brake Technology Launches From International Space Station

Two additional technologies will be demonstrated on TechEdSat-5. These include the ‘Cricket’ Wireless Sensor Module, which provides a unique wireless network for multiple wireless sensors, providing real time data for TechEdSat-5. The project team seeks to develop building blocks for larger scale systems that might enable future small or nanosatellite missions to reach the surface of Mars and other planetary bodies in the solar system.

Greetings, Orbiter.ch Full article

Ten minutes till this happens! I can’t watch it live but I’m excited to see what happens in the aftermath…

In about 20 minutes SpaceX will attempt to reuse a rocket booster they’ve already used before. If they succeed it could be a very serious step forward in space exploration capabilities.

Go SpaceX. Pleassssse…

Planets i learned about via youtube while procrastinating my english essay

Planet 55 Cancri e is basically a giant diamond. like the planet is a diamond. and it would be worth $26.9 nonillion

Planet Gliese 436 b is an ice planet that is constantly on fire do to its close proximity to its parent star. the ice doesn’t melt bc the planet’s gravity is so strong it physically prevents the ice from melting

Planet HD 189733b rains sideways glass…. constantly

Planet J1407-B has planetary rings that are 200x the size of saturn. if saturn’s ring were as big as J1407-B’s we’d be able to see them with our naked eye from earth AND they would dominate our sky and look larger than a full moon

Planet Wasp-12b rotates so close to its parent star that its slowly being consumed by the it

Planet Gliese 581c is one of the candidates for a planet that can support life however it orbits a tiny dwarf star and is tidally locked so one side is constantly subject to immense sunlight while the other is constantly in darkness. there’s a small area of the planet however, that is just the right temp to support life. u just can’t step out of said area. the skies are red and the plants would have be a black color instead of a green bc they would use infrared light for photosynthesis. (a message was actually sent to the planet in 2008 in hopes that there’s life on the planet but the message wont reach the planet until 2029).

Planet GJ 1214b is a water planet nicknamed “water world” is has no land at all and the water is so deep it goes down miles all the way to the planet’s core.

Planet Wasp-17b is the largest planet discovered thus far. its so large its existence contradicts our understanding of how planets are formed. and it has a retrograde orbit, so it orbits in the opposite direction of its parent star.

Planet HD 188753 has 3 suns you should have triple shadows and there would be almost daily eclipses. and no matter which direction u face on the planet u would always see a sunset

Planet HD106906b is the loneliest planet discovered thus far. its known as “super jupiter” bc its 11x bigger than jupiter. it orbits its parent star at a distance of 60 billion miles (which is v strange) hence why its the loneliest planet.

Planet Tres 2b is the darkest planet known. it reflects less than 1% of light (it reflects less light than coal and black acrylic paint). the tiny part of the planet that does reflect light is red making the planet glow a dim red.

I’m thinking of how to structure this whole podcast dealie so it’s more interactive, and what I’ve come up with is presenting a choice at the end of each episode of what people want to hear about next. Like a choose-your-own-adventure, except the adventure is me doing more research on a topic that I mentioned in the current podcast. I will retain veto power because there are some things I DEFINITELY want to cover, but it would be a cool way to see what other people are interested in with regards to space, to history, to technology, or to people!

Ep. 32 Black Holes - HD and the Void

I have mentioned black holes in previous episodes, but now feels like the right time to talk about them in their very own episode! I also discuss the new photos of the supermassive black hole in the galaxy Messier 87 and the telescope that was nee...

New Zealand was lovely, but I already touched on what I’d be tempted to talk about with my Southern Stars episode. A person I interviewed as a potential new housemate gave me the idea for this episode because the joy of outer space is truly everywhere and anywhere. The field of astrogeology was not something I had heard of before, though I had indirectly heard of Eugene Shoemaker. I knew the comet Shoemaker-Levy 9 was named after him (and Carolyn Shoemaker, his wife). It turns out he basically founded the modern field of astrogeology! So I talk about him for quite a while, too.

Below the cut are the glossary, transcript, sources, and music credits. Send me any topic suggestions via Tumblr message (you don’t need an account to do this, just submit as anonymous). You can also tweet at me on Twitter at @HDandtheVoid, or you can ask me to my face if you know me in real life. Subscribe on iTunes to get the new episodes of my semi-monthly podcast, and please please please rate and review it. Go ahead and tell friends if you think they’d like to hear it, too!

(The next episode is definitely going to be on famous comets, and I’m hoping to publish that episode in May.)

Glossary

active galaxy - a galaxy with a small core of emission embedded at the center. This core is typically very variable and very bright compared to the rest of the galaxy. These galaxies emit much more energy than they should; this excess energy is found in the infrared, radio, UV, and X-ray regions of the electromagnetic spectrum.

black hole -  a region of spacetime where a great deal of mass and energy have been compressed into a relatively small space. Black holes exert such strong gravitational effects that no mass or energy, not even light, can escape from inside them. There are supermassive black holes in galaxies that contribute to the development and life cycle of galaxies.

blazar - a subcategory of active galaxy, it is an extremely bright, distant object, powered by a black hole, which emits massive amounts of energy. It is distinct from a quasar because it is even brighter.

interferometry - a group of techniques to extract information from superimposing electromagnetic waves to create interference. In radio astronomy, this is done by using a wide spread of receivers to look at the same distant object, then bringing that data together with a correlator that can create a larger, clearer picture than an individual radio telescope alone could.

Messier object - a deep-sky object included on a list of 103-110 deep-sky objects made by Charles Messier and his colleagues in the 18th century in an attempt to prevent fuzzy, bright objects from being confused with comets.

torus - a donut shape.

quasar - a distant, massive celestial object that emits extremely large amounts of energy. These star-like objects may reflect a stage in the evolution of some galaxies.

Take a moment, look outside your window. 🌷🌼

Today is the #FirstDayOfSpring in the Northern Hemisphere, also known as the vernal equinox.

#DYK Earth’s tilted axis causes the season? Throughout the year, different parts of Earth receive the Sun’s most direct rays. So, when the North Pole tilts toward the Sun, it’s summer in the Northern Hemisphere. And when the South Pole tilts toward the Sun, it’s winter in the Northern Hemisphere.

These images are of Zinnias. They are part of the flowering crop experiment that began aboard the International Space Station on Nov. 16, 2015, when NASA astronaut Kjell Lindgren activated the Veggie system and its rooting “pillows” containing zinnia seeds.

Gretchen: On the International Space Station, you have astronauts from the US and from other English speaking countries and you have cosmonauts from Russia. And obviously it’s very important to get your communication right if you’re on a tiny metal box circling the Earth or going somewhere. You don’t want to have a miscommunication there because you could end up floating in space in the wrong way. And so one of the things that they do on the ISS – so first of all every astronaut and cosmonaut needs to be bilingual in English and Russian because those are the languages of space. Lauren: Yep. Wait, the language of space are English and Russian? I’m sorry, I just said ‘yep’ and I didn’t really think about it, so that’s a fact is it? Gretchen: I mean, pretty much, yeah, if you go on astronaut training recruitment forums, which I have gone on to research this episode… Lauren: You’re got to have a backup job, Gretchen. Gretchen: I don’t think I’m going to become an astronaut, but I would like to do astronaut linguistics. And one of the things these forums say, is, you need to know stuff about math and engineering and, like, how to fly planes and so on. But they also say, you either have to arrive knowing English and Russian or they put you through an intensive language training course. But then when they’re up in space, one of the things that they do is have the English native speakers speak Russian and the Russian speakers speak English. Because the idea is, if you speak your native language, maybe you’re speaking too fast or maybe you’re not sure if the other person’s really understanding you. Whereas if you both speak the language you’re not as fluent in, then you arrive at a level where where people can be sure that the other person’s understanding. And by now, there’s kind of this hybrid English-Russian language that’s developed. Not a full-fledged language but kind of a- Lauren: Space Creole! Gretchen: Yeah, a Space Pidgin that the astronauts use to speak with each other! I don’t know if anyone’s written a grammar of it, but I really want to see a grammar of Space Pidgin.
