Diving into New Magnetic Territory with the MMS Mission

Our Magnetospheric Multiscale Mission, or MMS, is on a journey to study a new region of space.  

On May 4, 2017, after three months of precisely coordinated maneuvers, MMS reached its new orbit to begin studying the magnetic environment on the ever-rotating nighttime side of Earth.

The space around Earth is not as empty as it looks. It’s packed with high energy electrons and ions that zoom along magnetic field lines and surf along waves created by electric and magnetic fields.  

MMS studies how these particles move in order to understand a process known as magnetic reconnection, which occurs when magnetic fields explosively collide and re-align.

After launch, MMS started exploring the magnetic environment on the side of Earth closest to the sun. Now, MMS has been boosted into a new orbit that tops out twice as high as before, at over 98,000 miles above Earth’s surface.

The new orbit will allow the spacecraft to study magnetic reconnection on the night side of Earth, where the process is thought to cause the northern and southern lights and energize particles that fill the radiation belts, a doughnut-shaped region of trapped particles surrounding Earth.  

MMS uses four separate but identical spacecraft, which fly in a tight pyramid formation known as a tetrahedron. This allows MMS to map the magnetic environment in three dimensions.

MMS made many discoveries during its first two years in space, and its new orbit will open the door to even more. The information scientists get from MMS will help us better understand our space environment, which helps in planning future missions to explore even further beyond our planet.

The upper atmosphere of the Sun is dominated by plasma filled magnetic loops (coronal loops) whose temperature and pressure vary over a wide range. The appearance of coronal loops follows the emergence of magnetic flux, which is generated by dynamo processes inside the Sun. Emerging flux regions (EFRs) appear when magnetic flux bundles emerge from the solar interior through the photosphere and into the upper atmosphere (chromosphere and the corona). The characteristic feature of EFR is the -shaped loops (created by the magnetic buoyancy/Parker instability), they appear as developing bipolar sunspots in magnetograms, and as arch filament systems in . EFRs interact with pre-existing magnetic fields in the corona and produce small flares (plasma heating) and collimated plasma jets. The GIFs above show multiple energetic jets in three different wavelengths. The light has been colorized in red, green and blue, corresponding to three coronal temperature regimes ranging from ~0.8Mk to 2MK.

This is what is happening in the sun when it is too bright to see details.

nasa The magnetic field lines between a pair of active regions formed a beautiful set of swaying arches, seen in this footage captured by our Solar Dynamics Observatory on April 24-26, 2017.
These arches, which form a connection between regions of opposite magnetic polarity, are visible in exquisite detail in this wavelength of extreme ultraviolet light. Extreme ultraviolet light is typically invisible to our eyes, but is colorized here in gold. This video covers almost two days of activity.

Beginnings of Gravity Pull!

Okay, okay. It definitely needs some polish, but it’s a start.
When the player is within the range of an object, they can press the LeftTrigger to pull the object into their orbit.

Next, will be the ability to eject the objects within the orbit. (and then polish. I hope!).

More next time :)

Mostly Mute Monday: Stunning Pictures Of The Milky Way’s Magnetic Field

“From the light’s polarization, we can reconstruct the galaxy’s magnetic field. And by superimposing it over the foreground emission map, we can see for the first time how our galaxy’s structure and magnetic field are interrelated. What we found was an intricate relationship between dust grains — the precursors to stars – and the giant magnetic structures we find, some of which extend for over a thousand light years in diameter.”

If you want to view the Milky Way in all its true splendor, you need to go beyond visible light, as the cosmic dust that gives rise to new stars also absorbs visible light, robbing us of a view of our galaxy. But those other wavelengths that are more transparent to the dust — infrared and microwave — are absorbed by Earth’s atmosphere. If we want to see what’s going on, we’ve got to go to space. With nine different frequency maps covering the entire sky, the ESA’s Planck satellite not only can determine what’s through that dust, but it can measure the effects of the Milky Way’s magnetic field due to the polarization of light, showing the future of star birth in our own galaxy.

After a short hiatus while we worked to figure it out, our Mostly Mute Monday series is back!

NASA’s MAVEN Discovers How Mars Lost Its Atmosphere

“The good news for us, mind you, is that the magnetic field here on Earth shows no sign of ceasing anytime soon. The dynamo in the core may do things like flip and reverse, swapping north-and-south magnetic poles, but we should continue to stay protected from the solar wind far into the foreseeable future: for billions of years (at least) to be sure. We could, conceivably, one day suffer the same fate as Mars, but our mass, our rotation and our active, dynamic core should keep the Earth’s magnetic field in business for at least as long as the Sun shines!”

If you had taken a trip to our Solar System four billion years ago, you would have found two worlds with liquid water oceans, temperate atmospheres and all the conditions we believe are needed for life. Earth would have been one of them, but Mars would have met all those criteria, too. It was long suspected that something happened to Mars around a billion years into the Solar System’s history that caused it to lose its atmosphere, something that should still be going on today. Thanks to NASA’s Maven mission, we’ve measured this atmospheric stripping by the Sun for the first time, and we’ve reached a few incredible conclusions, including that in about two billion years, Mars will be completely airless, and that if we were to terraform Mars today, it would hang onto this new atmosphere for millions of years.

Come get the full story of how Mars lost its atmosphere, and learn what NASA’s Maven mission has taught us so far!

Daddy’s Girl

Titled: ‘Daddy’s Girl.’ 

Pairing: Jensen Ackles x daughter!reader 

Summary/A/N:  “Imagine You are Jensen’s daughter and you guest star on Supernatural and Uncle Jared and Daddy play with you on set.” You should make a fic out of this. Well, sure! This was requested by @chrisssyym and I really hope you got what you wanted! 

Warnings: Single Daddy!Jensen, little angst, but lots of fluff! Italics are flashback. The bold is the flashback within the flashback.

Jensen didn’t appear the least bit surprised when at their next con someone asked after the latest Supernatural episode if that was his daughter who was the guest star. Jensen was more than happy to talk about his baby girl.
