1,000 Days in Orbit: MAVEN’s Top 10 Discoveries at Mars

On June 17, our MAVEN (Mars Atmosphere and Volatile Evolution Mission) will celebrate 1,000 Earth days in orbit around the Red Planet.

Since its launch in November 2013 and its orbit insertion in September 2014, MAVEN has been exploring the upper atmosphere of Mars. MAVEN is bringing insight to how the sun stripped Mars of most of its atmosphere, turning a planet once possibly habitable to microbial life into a barren desert world.

Here’s a countdown of the top 10 discoveries from the mission so far:

10. Unprecedented Ultraviolet View of Mars

Revealing dynamic, previously invisible behavior, MAVEN was able to show the ultraviolet glow from the Martian atmosphere in unprecedented detail. Nightside images showed ultraviolet “nightglow” emission from nitric oxide. Nightglow is a common planetary phenomenon in which the sky faintly glows even in the complete absence of eternal light.

9. Key Features on the Loss of Atmosphere

Some particles from the solar wind are able to penetrate unexpectedly deep into the upper atmosphere, rather than being diverted around the planet by the Martian ionosphere. This penetration is allowed by chemical reactions in the ionosphere that turn the charged particles of the solar wind into neutral atoms that are then able to penetrate deeply.

8. Metal Ions

MAVEN made the first direct observations of a layer of metal ions in the Martian ionosphere, resulting from incoming interplanetary dust hitting the atmosphere. This layer is always present, but was enhanced dramatically by the close passage to Mars of Comet Siding Spring in October 2014.

7. Two New Types of Aurora

MAVEN has identified two new types of aurora, termed “diffuse” and “proton” aurora. Unlike how we think of most aurorae on Earth, these aurorae are unrelated to either a global or local magnetic field.

6. Cause of the Aurorae

These aurorae are caused by an influx of particles from the sun ejected by different types of solar storms. When particles from these storms hit the Martian atmosphere, they can also increase the rate of loss of gas to space, by a factor of ten or more.

5. Complex Interactions with Solar Wind

The interactions between the solar wind and the planet are unexpectedly complex. This results due to the lack of an intrinsic Martian magnetic field and the occurrence of small regions of magnetized crust that can affect the incoming solar wind on local and regional scales. The magnetosphere that results from the interactions varies on short timescales and is remarkably “lumpy” as a result.

4. Seasonal Hydrogen

After investigating the upper atmosphere of the Red Planet for a full Martian year, MAVEN determined that the escaping water does not always go gently into space. The spacecraft observed the full seasonal variation of hydrogen in the upper atmosphere, confirming that it varies by a factor of 10 throughout the year. The escape rate peaked when Mars was at its closest point to the sun and dropped off when the planet was farthest from the sun.

3. Gas Lost to Space

MAVEN has used measurements of the isotopes in the upper atmosphere (atoms of the same composition but having different mass) to determine how much gas has been lost through time. These measurements suggest that 2/3 or more of the gas has been lost to space.

2. Speed of Solar Wind Stripping Martian Atmosphere

MAVEN has measured the rate at which the sun and the solar wind are stripping gas from the top of the atmosphere to space today, along with details of the removal process. Extrapolation of the loss rates into the ancient past – when the solar ultraviolet light and the solar wind were more intense – indicates that large amounts of gas have been lost to space through time.

1. Martian Atmosphere Lost to Space

The Mars atmosphere has been stripped away by the sun and the solar wind over time, changing the climate from a warmer and wetter environment early in history to the cold, dry climate that we see today.

Maven will continue its observations and is now observing a second Martian year, looking at the ways that the seasonal cycles and the solar cycle affect the system.

What are your favorite Latin phrases or just phrases in general?

omg this is a cool question, let me try to recall some of my favs:

  • per adua ad astra, and all it’s variations (per aspera ad astra, sic itur ad astra, and so on). they’re all various ways of saying “through hardship, you will go the stars”. Idk, ever since I first learned the phrase, it’s always stuck with me as one of the most beautiful expressions.
  • Veni, vidi, vici- I came, I saw, I conquered. It sounds imposing and powerful and like something i’d have tattoed on myself if i was a battle-scarred warrioress.
  • semper ad meliora- always towards better things. I like it simply because a) it sounds nice to say (which is a common factor for all my favorite phrases, tbh) and b) it’s inspirational, as cheesy as that seems.
  • Auribus Teneo Lupum- “I hold the wolf by the ears,” this one is actually an ancient proverb.
  • bellum se ipsum alet- “war feeds itself”
  • capax infiniti- “holding infinity”
  • luctor et emergo- “I struggle and emerge”
  • dum vivimus, vivamus- “while we live, let us live”
  • “ita vero” is a phrase I always wish I could have courage to throw out in casual conversation, since it just means “thus indeed” and it’d be hella eloquent to use it while trying to sound smart.
  • lux aeterna- “eternal light”
  • nec aspera terrent- “they do not fear the difficulties”

I walk with the grace of a thousand goddesses. Those who aren’t with me or scorned me only did so because they could not handle my grace or light. I am fire and eternal

When a girl loves a girl the touches are softer,
fingers like feathers, tracing underneath the breastbone in the midst of twilight.
When a girl loves a girl the tears are harder,
they fall like glass, clear like her eyes laced with honesty and love that smells like lavender
When a girl loves a girl the other girls tongues are sharper,
abomination falls from their lips, lips that have touched their friends in the dark, rich with intoxication
When a girl loves a girl the boys shrink into themselves,
a hurricane is cast around their heads, a rushing desire to have what they can’t, wanting to claim what is not theirs, demanding that it’s being ripped from their calloused hands.
When a girl loves a girl the world whispers, some louder than others
the indoctrinated have matches for fingers, lighting fires for our eternal souls to rot in
the preachers of peace shrug their shoulders, sometimes they chant for us, it’s never loud enough.
the planets sing for us as we dance among the stars,
When a girl loves a girl, she owns the universe.

Anime that surprised me despite their outward appearance/synopsis (not in any particular order)

Anime that I have misjudged…

1.) Silver Spoon (Gin no Saji) 

aka the show about farming

My thought going into this show: 

Why the fuck would anyone watch an anime about farming?”

“I’m only watching this because the author of FMA created this… but I doubt it’s going to be any good.”

My thoughts after watching: 

“Fucking hilarious. I laughed so hard in this show more than anything I’ve seen in a while.”

“You don’t even need to like agriculture- or know a single thing about it to enjoy this show.”

“The character development and all the characters in general are fantastic”

2.) Welcome to the NHK

aka the 24 episode anime about a NEET-stalker-hikikomori, his otaku kouhai, and a depressed teenage girl

My thought going into this show:

"I’ll watch it later- seems boring”

My thoughts after watching:

“This show has some of the best dark humor- seriously- a masterpiece. ”

“T an adventure that seems like an epic journey to those who seem to live in a small world, removed from society. ”

“Conspiracy. Conspiracy. Conspiracy.”

“SOBS”

3.) Ping Pong: The Animation

aka… the show… about pingpong with the weird art

My thought going into this show:

“Why ping pong out of all the sports- ping pong is like the least interesting sport”

"Strange art. I can’t get used to watching this”

(I pushed this show off for like about a year now)

My thoughts after watching: 

“If you haven’t watched this you’re missing out- this show barley has anything to do with ping pong. Just watch this amv and you’ll see > https://www.youtube.com/watch?v=UYzk0YjOZ0w

"The visuals are fantastic. I like how this studio took the risk to stand out like this. They made a good choice in making the art this way- it seems a bit more realistic and ‘closer to home’”

4.) Free! 

aka the gay swimming anime/ fan-service crap

My thought going into this show:

"As a girl… I like this kind of stuff but I’m not sure if this is worth the time.”

“Is there even a plot?”

My thoughts after watching:

“It’s more than just a gay swimming anime. It has fanservice- and it does live up to it’s nickname as the ‘gay swimming anime’ -but that’s just the humor in this show-

"Sure this show got more hype than it probably deserved- however- this show is also not all about swimming”

"Good message- deeper plot than first glance”

5.) Nobunaga Concerto

aka one knows this show, that one historic show with the weird art that no one watches

My thought going into this show:

"I’m bored out of my mind- but this will make me even more bored.”

“not interested in Japanese history

My thoughts after watching: 

"It’s not your traditional ‘realistic Japanese history drama’

“I found this show in a corner, the bottom of the stack beneath all of the great shows out this season- and it turned out to be the most interesting/ unique.”

"This is one of the best WRITTEN shows of all time- even in eng subs I can tell that the dialogue was thought out carefully ( but not tooo carefully )”

"It’s funny! The main character is quirky and clumsy.” “The Op/Ed is great- I have it on my ipod”


ALL IN ALL 

These five anime are one of the most unique and best shows I’ve ever seen in my whole life.
If there is a lesson gained from this- It’s to never be afraid to try something new

Because you never know… you might just come across a gem and you wouldn’t even know it.
