Mission Briefing: Juno

In ancient Roman mythology, Juno was the chief goddess, sister, and wife to Jupiter, king of the gods. Despite her husband’s tumultuous personality, Juno was loyal, and persistent in keeping tabs on Jupiter’s secret affairs.

On August 5, 2011, Juno—the JUpiter Near-polar Orbital—launched from Cape Canaveral and began its long journey to rendezvous with Jupiter. In 2013, Juno briefly returned to Earth’s orbit to propel itself on course by performing a gravitational slingshot maneuver on trajectory toward the gas giant.

Juno is now far enough away from the Sun’s gravity to be completely controlled by Jupiter’s gravitational forces, and on July 4, 2016, the spacecraft will perform a Jupiter orbital insertion (JOI) maneuver to stay in orbit. One wrong move, however, and Juno will fly off into deep space, never to return.

If successful, Juno will orbit Jupiter just over 30 times over the course of 20 months. But the danger doesn’t stop once the spacecraft is in orbit.

Jupiter’s gaseous clouds and fast rotational speed is literally a perfect storm generating high-energy particles that create a severe radiation environment. Juno will be exposed to a radiation dose of 20 million Rads—that is the equivalent of a human receiving 100 million dental X-rays!

Juno is equipped with a first-of-its-kind titanium vault—a high-tech armor suit—protecting all of the delicate sensors, detectors, and imaging equipment inside the spacecraft. This will hopefully significantly reduce the amount of radiation exposure so that Juno can collect as much data as possible.

So, what is Juno’s mission?

Also onboard Juno? Three special custom LEGO minifigures. From L to R: Galileo Galilei, Juno, and Jupiter.

The goal is to take measurements and observations of Jupiter’s atmosphere, with particular focus on the magnetosphere near the north and south poles. For a planet to be birthed into existence, it requires lots of heavy elements—in astronomy, this is any element heavier than hydrogen or helium.  Juno’s data can help scientists understand how these heavy elements become enriched during planetary formation. By comparing the elemental composition of Jupiter to that of our Sun, we can learn more about what separates a planet from a star.

While Juno’s mission will focus on Jupiter itself, the Galilean satellites (Jupiter’s four largest moons) may make their way into a picture or two. One moon is of great interest to scientists—Europa. This moon is completely covered in ice, but scientists believe that under that ice is a vast ocean that is possibly teeming with lifeforms. Future exploration of Europa is inevitable, so Juno needs to steer clear so that it doesn’t crash into the moon and potentially contaminate the natural environment. At the end of Juno’s 20 month orbital journey, it will end in a suicide mission directly into the heart of Jupiter. This ensures that the spacecraft won’t eventually cross paths with Europa (or any of the other moons).

I was lucky enough to be selected as a #NASASocial participant with an invitation to witness the arrival event and orbital insertion live from mission control at NASA’s Jet Propulsion Laboratory in Pasadena. While astronomy isn’t my field of expertise, I see this as a great opportunity to engage in science communication and outreach. I’ve been having a blast chatting with others online and I’m looking forward to broadening my horizons and learning from the Juno team on July 3rd-4th. You can expect another blog post or two during/after the event!

Yesterday, the Juno team held a live stream press conference with an update on the project (most of which is summarized in this post). They also fielded questions from the press and from the public via Twitter. As a #NASASocial participant, I live tweeted the press update, and even asked a question— which they answered!

I think one of the coolest things about NASA is how they prioritize engagement with the public. If it wasn’t for this passion toward outreach, I wouldn’t be going to JPL in a couple of weeks. This greatly humanizes science and inspires a culture of curiosity, and I’m glad to be a part of it!

On fear, faith, hope, and love

My heart is heavy from yesterday’s news of the Orlando shooting. And as I saw people sharing their thoughts, sadness, frustration, and anger, I thought “what else can I say that other’s aren’t already saying?” So I’ve kept my thoughts to myself.

I don’t often share things about my faith because I don’t like being preachy. I’m afraid that I’m going to offend someone. I don’t want to say the wrong thing and be pointed out as a hypocrite.

But as we are offering our thoughts and prayers—if we are praying “Your kingdom come, your will be done, on earth as it is in heaven”—that assumes that some action needs to be taken. There must be some action done here on earth to bring it closer as it is in heaven.

I can’t stay silent; we can’t be silent when our fellow brothers and sisters are grieving, even if that action is simply and humbly saying “my heart is broken and I am with you.”

All lives matter. Hate and violence is never the answer. We need to stop letting religion, politics, and pride be excuses for dividing us. We are called to LOVE and bring LIGHT into the darkness—love casts out fear. May our words and actions demonstrate this as we stumble along on this earth, and hope that it will one day be restored to something more beautiful.

Out of the Lazarus Pit

I tend to suffer from “Shiny Object Syndrome.” I get passionate about a new project, only to start a new one shortly thereafter. I brainstorm ideas, make lists and plans, and then forget about them. Repeat ad nauseum.

It’s like my brain is forever stewing in a Lazarus Pit.

Lately, I’ve found myself getting more and more invested in my passion for science writing and communication. I’m committed to several projects that continue to inspire me in new ways. This means it was time to start anew with blogging and to be more proactive about curating all of my “sci comm” projects in one spot. *BAM* Hello, new website!!

I’ve imported a few old posts from my previous blog, because I think it’s important to see how my writing has evolved over the years. I’m looking forward to writing in this new space, and hope that it continues to provide new opportunities for me to geek out and never stop learning!

The Power of Introverts

One of these days I need to write a detailed blog post about my love for the MBTI assessment and how it helped me understand my introversion. [For the record, I’m an INTJ]

I have always felt like a social outlier. I never understood why people saw me as aloof or “shy,” when I was crazy and exuberant at home with my family. Or why people didn’t get that I wasn’t a “party person” and would rather hang out and watch Star Wars with just one or two of my best friends. I never understood why I didn’t like big crowds, despite a love for visiting busy cities like Chicago or New York City.

It wasn’t until well after my college years — the period when all the stress and confusion about how I fit into society led to episodes of depression and anxiety — when I finally discovered what it meant to be an INTROVERT. I learned that introversion didn’t mean shy or socially inept, but rather it meant that I prefer to internalize my thoughts as a way to “recharge” after periods of socialization. It meant that I am be better at communicating through writing rather than on the spot discussion…and that I much prefer talking about topics I’m passionate about rather than participating in “small talk.”

Shortly after I learned the true definition of introversion vs. extroversion, I came across a TED talk by Susan Cain entitled, “The Power of Introverts.” Her talk introduces the concepts she thoroughly researched for her book, QUIET: The Power of Introverts in a World that Can’t Stop Talking — concepts that hit me over the head like a lightbulb, or more like a giant lighthouse:

“Oh, that makes *so* much sense! There are other people that think that way, too?! I had no idea that’s why I acted that way…”

It’s been about three years since discovering I am an introvert and since finding that TED talk. But I’ve only just started reading Cain’s book. I have read and researched a lot about introversion in the past three years, and having that knowledge base already makes reading QUIET feel like revisiting an old friend. I was hoping to finish the book before today so that I could write a reflective review, but I’m going to just savor my time reading and relating to what Susan Cain writes.

Are you an introvert or an extrovert? How does that affect the way you experience the world?

Jack of all trades…

I have always identified as a “renaissance woman” — I’ve adopted many hobbies and skills and interests over the years, and have no shame in saying that I have talent in those areas. But the saying goes, being a jack-of-all-trades often means that one’s interest is spread so thin that the result is being a master-of-none.

I take great pride in the things I’m interested in and passionate about, while at the same time I show great contempt toward myself because I don’t excel at what I started, or don’t finish a project. Because of my natural tendency to think about everything, my brain is really good at formulating ideas. But I rarely accomplish the task of brining those ideas to fruition.

I do think the many facets of my personality and my interests make me unique, and also make me capable of achieving a lot of interesting things. I love art, science, geek culture, music, etc. I want to be able to share my passion for these things in a way that is accessible for others so that they might learn something about themselves that they haven’t thought of before. I think being a jack-of-all-trades can be an inspiring way to live life. We don’t need to be perfect masters at anything. We just need to love who we are and love what we do.
