Solar System: 2016 Preview

What do we have planned for 2016? A return to the king of planets. A survey of mysterious Ceres. More postcards from Pluto. Anyone who follows solar system exploration in 2016 is in for quite a ride. Last year was one for the record books – and now here are 10 things to look forward to in the new year. See also: what we have planned agency wide for 2016.

Juno Arrives at Jupiter

Solar System: 2016 Preview

July 4, 2016 is arrival day for the Juno mission, the first sent expressly to study the largest planet in the solar system since our Galileo mission in the 1990s. Humans have been studying Jupiter for hundreds of years, yet many basic questions about the gas world remain: How did it form? What is its internal structure? Exactly how does it generate its vast magnetic field? What can it tell us about the formation of other planets inside and outside our solar system? Beginning in July, we’ll be a little closer to the answers.

OSIRIS-REx Takes Flight

Solar System: 2016 Preview

The OSIRIS-REx mission, short for Origins-Spectral Interpretation-Resource Identification-Security-Regolith Explorer, sets sail for an asteroid in September. The spacecraft will use a robotic arm to pluck samples from the asteroid Bennu to help better explain our solar system’s formation and even find clues to how life began.

Dawn Sees Ceres Up Close

Solar System: 2016 Preview

After an odyssey of many years and millions of miles, in December the Dawn spacecraft entered its final, lowest mapping orbit around the dwarf planet Ceres. The intriguing world’s odd mountains, craters and salty deposits are ready for their close-ups. We can expect new images of the starkly beautiful surface for months.

Cassini Commences Its Grand Finale

Solar System: 2016 Preview

In late 2016, the Cassini spacecraft will begin a daring set of orbits called the Grand Finale, which will be in some ways like a whole new mission. Beginning this year and extending into next, the spacecraft will repeatedly climb high above Saturn’s poles, flying just outside its narrow F ring 20 times. After a last targeted Titan flyby, the spacecraft will then dive between Saturn’s uppermost atmosphere and its innermost ring 22 times. As Cassini plunges past Saturn, the spacecraft will collect rich and valuable information far beyond the mission’s original plan.

New Horizons Sends More Postcards from Pluto

Solar System: 2016 Preview

We have stared slack-jawed at the images and discoveries from last year’s Pluto flyby, but the fact is that most of the data that New Horizons collected remains on board the spacecraft. In 2016, we’ll see a steady release of new pictures — and very likely some expanded answers to longstanding questions.

Mars Missions March Forward

Solar System: 2016 Preview

With five of our missions continuing their Martian quests, 2016 should be a good year for discoveries on the Red Planet.

Mars Odyssey

Mars Opportunity

Mars Reconnaissance Orbiter

Mars Curiosity

MAVEN

Mercury Transits the Sun

Solar System: 2016 Preview

A transit is a very rare astronomical event in which a planet passes across the face of the sun. In May, Mercury will transit the sun, on of only thirteen Mercury transits each century on average.

LRO Keeps an Eagle Eye On the Moon

Solar System: 2016 Preview

The Lunar Reconnaissance Orbiter (LRO) will extend its run in 2016, scanning the moon’s surface with its sharp-eyed instruments, investigating everything from lava tube skylights to changes at the Apollo landing sites.

Spacecraft Fly Under Many Flags

Solar System: 2016 Preview

Our partner agencies around the world will be flying several new or continuing planetary missions to destinations across the solar system:

Akatsuki at Venus

ExoMars

Mars Express

Mars Orbiter Mission

Rosetta at Comet 67/P

Technology Demonstration Missions Push the Envelope

Solar System: 2016 Preview

We’re always looking for new frontiers on distant worlds, as well as the technology that will take us there. This year, several missions are planned to take new ideas for a spin in space:

Deep Space Atomic Clock

NODES

LDSD

Stupid Lab Mistakes: a Constant Across All Levels of Experience

So today was day one of a tyrosinase lab. We had to centrifuge our organic matter sample (homogenized mushroom gills) to separate the soluble proteins from the rest of the tissue, and we counterbalanced our sample with an identical centrifuge tube of equal weight filled with water. We did all of this under the supervision of a TA and our professor.

My lab partners and I have used centrifuges many times before, but what we (and the instructors) failed to notice was that these particular tubes required an adapter for this particular centrifuge. We were spinning it up to about 7000 rcf when we heard a muffled “bang,” then the centrifuge slowed to a stop. When we opened it up, we discovered that the water tube had EXPLODED, shattering into a hundred little plastic pieces. the tube containing our organic sample slurry was thankfully intact, but it was badly warped and cracked. We spent the next 20 minutes or so carefully wiping water off every nook and cranny of the centrifuge interior, thanking our lucky stars that it wasn’t mushroom gloop.

I keep thinking that gaining more practical lab experience will save me from this kind of thing, but if the three different generations of chemists present couldn’t keep it from happening then there is no hope. These incidents are the things that add unexpected excitement to my life, though, so I suppose it’s not all bad.

Iconic American Landscape Photos, Recreated with Junk Food

For their project “Processed Views,” which is currently on view in the exhibit “Changing Circumstances” at the FotoFest 2016 Biennial, the collaborators Barbara Ciurej and Lindsay Lochman have produced cheeky dioramas that pull Carleton Watkins’s iconic images brashly into the industrial modern world. Using all manner of highly processed foods—Flamin’ Hot Cheetos, Coca-Cola, marshmallows, fleshy stacks of bologna—they recreated the photographer’s famous landscapes from Yosemite and other California sites as garish candy lands.

Graphene Safely Interacts With Neurons In The Brain

Graphene Safely Interacts With Neurons in the Brain

Researchers have shown that graphene can be used to make electrodes that can be implanted in the brain, which could potentially be used to restore sensory functions for amputee or paralysed patients, or for individuals with motor disorders such as Parkinson’s disease.

The research is in ACS Nano. (full access paywall)

Also, while this is on my mind. In my master’s-level food toxicology class today we discussed various genetically modified crops and watched part of a documentary about them, and as someone with a food science degree I would like to be clear about the following:

The only health risk that has been shown to us throughout twenty plus years of having genetically modified crops as part of the food system is that there is a possibility of introducing proteins that could cause allergic reactions. New strains are required to be tested for this, of course, but that is a practical risk that needs to be closely monitored.

The objection to GM in general should be the patenting of genes and other legal matters; there are a number of crops that have been saved from blight and overall extinction via modification in the past two decades, and much like putting up inaccessibly expensive paywalls to scientific journals, patenting of genes within crops limits our ability within universities, small research companies, etc to make significant breakthroughs to further the scientific progress of humanity. 

Furthermore. People think of organic crops as the environmentally-friendly option. If you believe this, please pay attention to what I’m about to say. Current regulations dictate that to have a crop classified as organic the land on which the crop is grown has to have been pesticide-free for a significant amount of time. There is no interim label available to farmers. So what do they do? Do they use no pesticides and take the losses from disease and insects for a decade, waiting for a time in which they are allowed to reclassify their crops in such a way that they can sell them for more money?

Of course they don’t. It isn’t practical. You can say what you like about how the system is structured; I’d personally like to see an interim classification come into play. But what farmers actually do, and states like Montana are feeling the full effects of this–they clear-cut forests and plant their organic crops on entirely new land.

You want to tell me that clear-cutting forests is environmentally friendly? It’s not. Hell, for all that people make a big deal about saving the environment by limiting how much paper they use, paper production is done in a more sustainable manner (because the paper farms replant their trees in a regular cycle so as to not deplete their sources; they don’t just go out and cut down random trees). 

There are objections to be had in regards to GM crops on a legal basis. On a scientific one, there isn’t much. Call them frankenfoods all you want; look up what most commercially-sold produce truly looks like in the wild with no modification and you will learn very quickly that all foods have been modified in some way over the years through conventional breeding. We just think of that differently. 

Biotechnology is not the enemy. Pseudoscience tells us that this is the case. Pseudoscience also tells us that we should seek out natural supplements instead of medicine, and, well… that’s a rant for another day, but suffice to say it’s an even more dubious proposition.

Don’t buy into it.

BLUE MOON

BLUE MOON

Suli Ayad, an undergraduate working in Kenneth Hanson’s lab at Florida State University, synthesized these crystals of 7-bromo-2-naphthol in a round-bottom flask. Under ultraviolet light, the crystals glow bright blue because when 7-bromo-2-naphthol molecules absorb the energy in UV light, they get excited. The molecules then release that energy as blue light to return to their lower-energy ground state. But Hanson’s group is interested in the chemical’s excited state for another reason: In the excited state, the molecule is more than 10 billion times as acidic as it is in the ground state. This is due to a shift in electron density away from 7-bromo-2-naphthol’s OH group. The switchable increase in acidity makes the molecule a useful catalyst in organic chemistry.

Vacuum distillation of polyaromatic compounds could be fun. 

In this case I only had to sit with an UV lamp to see when will my compound distill, since it had a bright blue fluorescence (as seen), while the side products of the reaction did not had any visible emission when irradiated with UV light.
