A Teenager Designed A Pocket-sized Satellite That Will Fly On A NASA Mission

A teenager designed a pocket-sized satellite that will fly on a NASA mission

An 18-year-old created the world’s lightest functioning satellite, and it’s going to be launched on a real NASA mission next month.

Rifath Sharook, who is from Tamil Nadu, India, made the pocket-sized satellite for a competition called Cubes in Space, which is an international design challenge that asks students aged 11 to 18 to fit their space-worthy invention inside a 13-foot cube.

The pocket-sized 3-D printed satellite is much smaller than that. It weighs just 0.14 pounds and will measure the rotation, acceleration and magnetosphere of Earth, Sharook told Business Standard. Read more (5/17/17)

A New Angle on Two Spiral Galaxies for Hubble’s 27th Birthday

In celebration of the 27th anniversary of the launch of NASA’s Hubble Space Telescope on April 24, 1990, astronomers used the legendary telescope to take a portrait of a stunning pair of spiral galaxies. This starry pair offers a glimpse of what our Milky Way galaxy would look like to an outside observer. The edge-on galaxy is called NGC 4302, and the tilted galaxy is NGC 4298. These galaxies look quite different because we see them angled at different positions on the sky. They are actually very similar in terms of their structure and contents.

The hardest part of determining longitude was figuring out how sailors could find their longitudinal coordinates at sea. There were a lot of methods proposed but adding a ship into the equation makes precision difficult. Learn about the Longitude Act of 1714 and how, even though this podcast loves astronomy, the astronomical method might not always be the best option.

Below the cut are my sources, music credits, a timeline of the astronomers and engineers and clockmakers I mention, a vocab list, a really cool resource that lets you drag continents all over a flattened map of Earth to compare their sizes at different latitudes, and the transcript of this episode. Let me know 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 check out the podcast on iTunes, rate it or review it if you’d like, subscribe, and maybe tell your friends about it if you think they’d like to listen!

(My thoughts on the next episode were the Voyager golden records, space race history, the transit of Venus, or maybe something about the Moon landing. I’m loving Edmond Halley again these days, too. I’m prepping to interview a friend about her graduate-level research into the history of the universe and possibly dark matter, too. Let me know by the 20th and I’ll hopefully have the next podcast up on September 25th! If not then, I’ll push for October 2nd.)

Glossary

azimuth -  a section of the horizon measured between a fixed point and the vertical circle passing through the center of an object. See example in the link. 

equator - Earth’s zero line of latitude. It’s the place on Earth where the Sun is directly overhead at noon on the vernal and autumnal equinoxes.

kamal - an Arabic navigation tool consisting of a knotted string and a piece of wood. A navigator would tie a knot in the string and, by holding it in their teeth, sight the North Star along the top of the wooden piece and the horizon along the bottom. To return home, the navigator would sail north or south to bring Polaris to the altitude they had observed in their home port, then turn left or right and sail down the latitude, keeping Polaris at a constant angle. Over time, Arab navigators started tying knots at regular intervals of a fingerwidth, called an issbah, that’s about 1 degree and 36 minutes.

magnetosphere - an invisible barrier that surrounds a celestial objet. It is often generated by the movement of the liquid metal core of the object. Around a planet, it deflects high-energy, charged particles called cosmic rays that can either come from the Sun or, less often, from interstellar space.

prime meridian - Earth’s zero degree of longitude. In current maps and time zones, this invisible, imaginary line runs through London, England.

sextant - a device used to determine an observer’s location based on the observation of a known celestial object and a lot of calculation. It is still in use by sailors.

tropic of cancer - a line of latitude that marks where the Sun will be at noon on the summer solstice.

tropic of capricorn - a line of latitude that marks where the Sun will be at noon on the winter solstice.

After over a century of observations and several theories, scientists may have finally nailed the origin of the high-speed plasma blasting through the Sun’s atmosphere several times a day. Using a state-of-the-art computer simulation, researchers have developed a detailed model of these plasma jets, called spicules.

The new findings answer some of the bigger questions in solar physics, including how these plasma jets form and why the Sun’s outer atmosphere is far hotter than the surface.

“This is the first model that has been able to reproduce all the features observed in spicules,” Juan Martinez-Sykora, lead author and astrophysicist at the Bay Area Environmental Research Institute in California, told ScienceAlert.

What is an upcoming project/mission you're most excited for?

It is likely that I’ll be assigned a mission to the International Space Station (ISS) within the next few years.  We’ve had a continuous presence on the Space Station for 17 years now, along with our international partners (Russian Space Agency, European Space Agency, Japanese Space Agency, and Canadian Space Agency).  Missions on the ISS typically last 6 months.  I’m incredibly excited to contribute to the impressive array of scientific experiments that we are conducting every day on ISS (I am a scientist after all!), and very much look forward to the potential of going for a spacewalk and gaining that perspective of gazing down on the fragile blue ball that is our home from above.  Beyond that, being part of test missions on the Orion spacecraft (currently under construction at NASA!) would be an extraordinary opportunity.  The current NASA plan is to send astronauts in Orion in a mission that will go 40,000 miles beyond the Moon in the early 2020s, reaching a distance further than that ever travelled by humans.  I’d certainly be game for that!

Merging Galaxies Have Enshrouded Black Holes

NASA - NuStar Mission patch. May 9, 2017 Black holes get a bad rap in popular culture for swallowing everything in their environments. In reality, stars, gas and dust can orbit black holes for long periods of time, until a major disruption pushes the material in. A merger of two galaxies is one such disruption. As the galaxies combine and their central black holes approach each other, gas and dust in the vicinity are pushed onto their respective black holes. An enormous amount of high-energy radiation is released as material spirals rapidly toward the hungry black hole, which becomes what astronomers call an active galactic nucleus (AGN). A study using NASA’s NuSTAR telescope shows that in the late stages of galaxy mergers, so much gas and dust falls toward a black hole that the extremely bright AGN is enshrouded. The combined effect of the gravity of the two galaxies slows the rotational speeds of gas and dust that would otherwise be orbiting freely. This loss of energy makes the material fall onto the black hole.

Image above: This illustration compares growing supermassive black holes in two different kinds of galaxies. A growing supermassive black hole in a normal galaxy would have a donut-shaped structure of gas and dust around it (left). In a merging galaxy, a sphere of material obscures the black hole (right). Image Credits: National Astronomical Observatory of Japan. “The further along the merger is, the more enshrouded the AGN will be,” said Claudio Ricci, lead author of the study published in the Monthly Notices Royal Astronomical Society. “Galaxies that are far along in the merging process are completely covered in a cocoon of gas and dust.” Ricci and colleagues observed the penetrating high-energy X-ray emission from 52 galaxies. About half of them were in the later stages of merging. Because NuSTAR is very sensitive to detecting the highest-energy X-rays, it was critical in establishing how much light escapes the sphere of gas and dust covering an AGN. The study was published in the Monthly Notices of the Royal Astronomical Society. Researchers compared NuSTAR observations of the galaxies with data from NASA’s Swift and Chandra and ESA’s XMM-Newton observatories, which look at lower energy components of the X-ray spectrum. If high-energy X-rays are detected from a galaxy, but low-energy X-rays are not, that is a sign that an AGN is heavily obscured.

The study helps confirm the longstanding idea that an AGN’s black hole does most of its eating while enshrouded during the late stages of a merger. “A supermassive black hole grows rapidly during these mergers,” Ricci said. “The results further our understanding of the mysterious origins of the relationship between a black hole and its host galaxy.” NuSTAR is a Small Explorer mission led by Caltech and managed by NASA’s Jet Propulsion Laboratory for NASA’s Science Mission Directorate in Washington. NuSTAR was developed in partnership with the Danish Technical University and the Italian Space Agency (ASI). The spacecraft was built by Orbital Sciences Corp., Dulles, Virginia. NuSTAR’s mission operations center is at UC Berkeley, and the official data archive is at NASA’s High Energy Astrophysics Science Archive Research Center. ASI provides the mission’s ground station and a mirror archive. JPL is managed by Caltech for NASA.

Ep. 8 Planets - HD and the Void
Eight planets in the solar system or nine? I go into depth with nine because I grew up with Pluto. The first five planets are visible to the naked eye but how did we find Uranus, Neptune, and Pluto? What are we doing to still learn about our close...

Earth is a super special world. It has life on it, and getting conditions just right so that life will survive is an incredibly difficult task. Other planets and other moons in our solar system may look like they could have life on them, but it just didn’t happen.

Life on other planets is for a different episode, though. In this one, I’m talking about what we can see on our close neighbors, the eight (maybe seven?) planets in our solar system. Learn how they were discovered, what naming conventions we use for them and their moons, how to differentiate between them, and what probes we’ve sent out to learn more about them. Also enjoy snippets from the lovely orchestral suite written for each planet by Gustav Holst! It’s the longest episode so far but I promise it’s worth it.

There’s a timeline below the cut in addition to the other resources because hooboy did I mention a lot of people. I may also put together a timeline of probes... But that’s for another podcast. Maybe the next podcast! Let me know what you think I should research by messaging me here, tweeting at me at @HDandtheVoid, or asking me to my face if you know me in real life. And please check out the podcast on iTunes, rate it or review it if you’d like, subscribe, and maybe tell your friends about it if you think they’d like to listen! Also below the cut are my sources, music credits, vocab list, and the transcript. I mention a book, a play, a poem, and a few works of art, and I quote an astronomy book in this episode so if you want to see that written down, those sources are there as well.

(My thoughts for the next episode were spectroscopy, auroras, or probes through the ages. Let me know by the 21st and I’ll have the next podcast up by July 31!)

Glossary:

auroras - a light display that occurs when a magnetosphere is sufficiently disturbed by solar wind that charged particles scatter into the upper atmosphere and lose their energy.

magnetosphere - an invisible barrier that surrounds a celestial objet. It is often generated by the movement of the liquid metal core of the object. Around a planet, it deflects high-energy, charged particles called cosmic rays that can either come from the Sun or, less often, from interstellar space.

prograde - when a planet spins from east to west.

retrograde - when a planet spins from west to east.

sol - a unit of time measuring one Martian day, or 24 Earth-hours and 40 Earth-minutes. The immediately previous Martian day is called yestersol.

transit of Mercury/Venus - when a planet passes in front of the Sun.

“But tides raised by the Sun in the planet’s molten middle gradually damped Mercury’s rotation down to its present slow gait” (34).

“Light and heat always hit Mercury dead on, while the north and south poles, which receive no direct sunlight, remain relatively frigid at all times” (35).

“Venusian clouds comprise large and small droplets of real vitriol—sulfuric acid along with caustic compounds of chlorine and fluorine. They precipitate a constant acid rain, called virga, that evaporates in Venus’ hot, arid air before it has a chance to strike the ground” (61).

“…Neptune, where the voices of a female choir, sequestered in a room offstage, are made to fade out at the finale (with no sacrifice in pitch) by the slow, silent closing of a door” (165).

Holst: “Saturn brings not only physical decay but also a vision of fulfillment” (165).

“They occupy a nearby region of perpetual fragmentation known as the Roche zone, named for the nineteenth-century French astronomer Edouard Roche, who formulated the safe distances for planetary satellites” (172).

“It's near twin, Neptune, reveals a more complex beauty in subtle stripes and spots of royal to navy blue, azure, turquoise, and aquamarine” (200).

“This outlying population offered Pluto a new identity—if not the last planet, then the first citizen of a distant teeming shore” (214).
