In December NASA announced that it had narrowed down its potential list of planetary science
missions to two.
There's the Comet Astrobiology Exploration Sample Return (or CAESAR), a mission that
would return to Rosetta's Comet 67P and bring a sample back to Earth.
And then there's Dragonfly, a nuclear-powered helicopter that would buzz around in the atmosphere
of Saturn's moon Titan, exploring this fascinating world.
Sadly, there can only be one mission.
And so, NASA will let both missions continue working out the details until the final decision
can be made in mid-2019.
And if all goes well, the chosen mission will set off in middle of the 2020s.
Comet sample return or Titan helicopter, which one will it be?
In order to help out NASA with their decision making process, I've teamed up with Tim
Dodd, the Everyday Astronaut, to advocate for each of the missions.
I'm going to do everything I can to convince you that a comet sample return mission makes
the most sense, while Tim's going to advocate for the Titan Dragonfly.
And then, in the end, we'll give you a poll where you can vote.
We'll pass along the vote to the decision makers, and I'm sure they'll dismiss it
for the hilarious, and unhelpful YouTube stunt that it is.
Phew, I've got
to
advocate AGAINST a nuclear-powered helicopter on Titan.
Okay… here goes.
Comets are some of the most important objects of study in the Solar System.
They're relics, frozen in time from the earliest moments of our Solar System's history.
It's believed they delivered water and organic materials to the newly forming Earth, and
could have been pivotal to our understanding of how life first got started, billions of
years ago.
It's not surprising that they've been a target for several space missions.
The first mission to reach a comet was in 1985, when the International Comet Explorer
passed within 8,000 kilometers of Comet Giacobini-Zinner.
Other missions got even closer, like ESA's Giotto, which came within 200 kilometres of
Comet Grigg-Skjellerup in 1992.
NASA's Stardust mission passed through the tail of Comet Wild 2 in 2004, and brought
samples back to Earth for study.
NASA's Deep Impact smashed into Comet Tempel 1 in 2005, gouging out a crater, revealing
the comet's interior to a partner spacecraft.
But the one you're most familiar with was the European Space Agency's Rosetta Mission,
launched back in 2004 to perform the detailed study of Comet 67P/Churyumov-Gerasimenko.
Not only would it go into orbit, but it would try to land a separate spacecraft down on
the surface of the comet.
On August 6th, 2014, Rosetta arrived at the comet, and a few months later, it deployed
its Philae lander in an attempt to sample the surface.
The orbiter did great, returning high-resolution images of the surface of the comet.
The lander, not so much.
Its harpoons failed to fire, and it bounced gently a couple of times off the soft surface
of 67P, eventually coming to rest on its side.
Even if Philae had been successful, and been able to send back detailed information about
the surface of the nucleus of a comet, there's only so much it could do.
The next step in this journey to understanding comets, and helping them unlock the secrets
of the early Solar System is to bring a sample back to Earth.
Planetary scientists need to get their hands on a chunk of cometary nucleus, here on Earth,
where they can run it through every experiment and mass spectrometer they can get their hands
on.
We're entering the age of sample returns.
We've got Moon rocks from the Apollo missions, OSIRIS-REx is on its way to Asteroid Bennu
to bring us home a spacerock, missions are in the works to bring a sample back from Mars.
We need a chunk of a comet.
Dr. Steve Squyres, the principle investigator of NASA's Spirit and Opportunity Rovers
is back with a new mission: Comet Astrobiology Exploration Sample Return (or CAESAR).
Its purpose will be to fly to 67P, send a lander down to the surface, retrieve a sample
in a pristine, comet-like state, and bring it back to Earth.
When the sample returns to Earth, planetary scientists will be able to open it up, gases
and all, and study the comet to their heart's content, from the comfort of their earthly
laboratories.
The ESA scientists chose 67P as a target for a good reason.
In 1959, the comet had a close flyby with Jupiter, changing its orbit to send it closer
to the inner Solar System.
For at least 10,000 years before that, it was orbiting much farther from the Sun, safe
from the intense radiation.
This brought a relatively fresh comet from deep space into a region we could reach with
our spacecraft.
It's the perfect time capsule to tell us what the Solar System looked like eons ago.
The goal is to better understand how comets formed and what role they played in the early
Solar System.
Are they made from raw materials that clumped together during the formation of the Solar
System?
Were they processed through interactions with other objects in the Solar System?
Or are comets leftover chunks from shattered icy planets and other Kuiper Belt Objects?
Did they deliver water and organic materials to the early Earth to help life get going?
Now you know the history of cometary exploration and why the CAESAR mission is so important.
And in a second, I'm going to explain how the mission will work, but first I'd like
to thank:
Sherman Figura Steven Hill
Nicholas Verheyden Alexander Afanasyev
Rosemary Williams Gary Agnesini (Ag-na-si-ni)
And the rest of our 804 patrons for their generous support.
If you love what we're doing and want to get in on the action, head over to patreon.com/universetoday.
If all goes well, The CAESAR mission will launch in the summer of 2024 from Cape Canaveral.
It'll be equipped with an ion engine, allowing it to reach 67P in December of 2028.
The spacecraft will go into orbit around the comet, and then slowly lower its orbit over
several months, examining it in greater and greater detail.
It'll map out the surface, and search for any differences that have occured since Rosetta
made its maps, helping scientists understand how comets change over the course of a decade.
Mission planners will examine these surface maps and pick out candidate sites for CAESAR
to acquire its sample from.
Eventually, it'll be mapping out the surface down to a resolution of 0.6 cm per pixel.
Once the sites have been chosen, CAESAR will be ready to perform its touch-and-go operation
to sample material from the surface of 67P.
It'll have enough fuel on board for three attempts to get a sample.
The mission is inspired by NASA's OSIRIS-REx spacecraft, which is already on its way to
retrieve a sample from Asteroid Bennu.
So we'll already know if this technique is going to work.
The spacecraft will perform a deorbit burn, moving it closer to the surface of the comet.
Then it'll touch down for 5 seconds, suction up a bit of material, and then kick off into
space again.
It'll image the area at a resolution of 1 mm/pixel, giving scientists context for
where the sample came from.
Collecting the sample is going to be one of the toughest parts of the mission.
As we learned with Rosetta and Philae, trying to land on the surface of a comet is hard
enough.
Getting back out into space again is going to be even harder.
CAESAR is equipped with a special grabber called the Sample Acquisition System.
This is a suction cup-like device that can tilt to match the slope of the surface that
the lander touches down on.
When it senses the surface of the comet, it releases a set of spring-loaded ripper tines
that break up the crusty surface for easier collection.
Then it uses a pneumatic system to blast out high purity nitrogen gas around the sampling
cone, shaking up the comet material and directing it into the spacecraft's Sample Containment
System.
Up to 80 grams of cometary material will be captured for scientists at home to study.
But the actual cometary material is only half the story, the spacecraft will also pull out
any gases coming from the sample, and store that in a separate container.
This will give planetary scientists the best possible sample to study when it gets back
home.
It will then warm the samples to the exact temperature the comet experiences when it's
farthest from the Sun.
CAESAR will drift with Comet 67P for another 4 and a half years until it's in position
to make a burn back to Earth.
The sample will be transferred to a special landing capsule that will survive re-entry
through the Earth's atmosphere, delivering the pristine chunk of comet to waiting scientists.
And if all goes well, it'll return the sample to Earth in 2038, putting a piece of an actual
comet nucleus into the hands of scientists around the world.
By keeping it cold and pristine, researchers will be able to study it for clues for decades
to come.
Right now, NASA's OSIRIS-Rex mission is on its way to rendezvous with Asteroid Bennu
in 2018.
Then it will pick up a sample and return it back to Earth by 2023.
Planetary scientists will be able to study this sample in incredible detail, with the
best laboratories available to them here on Earth.
The CAESER mission will do the same, but provide a chunk of a comet to scientists to study.
Where did the Earth's water come from?
How early did organic materials form in the Solar System?
How did they come together to form planets?
By finally getting their hands on a chunk of a comet, scientists will have valuable
clues to these and many more questions about the Solar System.
Now it's Tim's turn.
Head on over to his channel and learn all about the Dragonfly mission to Titan.
And when you've made your decision, click the link in the shownotes to vote for your
favorite.
Whichever way you'd vote, let me know your thoughts in the comments.
Or just rage at the injustice of even having to choose in the first place.
Comet, Titan and why not, how about a mission to Venus?

Understanding SEO - Increasing Your Business's Website Traffic - Duration: 4:11.
What's up Fish Fans!
My name is Marcus.
You're watching Marketing Madness, the Blue Fish vlog!
Our goal is to address common questions that business owners may have about marketing,
sales, and business.
This week we will be addressing search engine optimization, informally known in the industry
as S-E-O.
SEO is one of those spaces that can get a bit confusing, especially for anyone that
isn't in this industry.
Not to mention Google and other search engines seem to be updating their algorithms weekly
to keep us on our toes.
So today I will explain what SEO is for those of you who are not familiar, and then really
dive into what is working for us.
To keep this week's video from being 97 hours long, we will not be explaining things that
an intermediate marketer should already be familiar with.
Let's start with an explanation of what SEO is just to build a vocabulary for this
topic.
SEO is defined as the practice of increasing the quantity and quality of traffic to your
website through organic search engine results.
One of the most important aspects of SEO that you can directly control is content marketing.
Outside of social media, so few people do it correctly on a small business or local
level.
Every piece of content you create for your website should have a plan and a purpose behind
it.
For example, if you create an article for your website, you need to make sure that you
focus in on your target keyword and its longtail variations.
As if creating content targeting specific keywords was not enough, your content MUST
be engaging.
Google makes note of whether people searching for those keywords bounce when visiting a
link that has been provided in a search result.
The act of clicking on a search result and hitting the back button quickly is a bounce.
User experience is a critical ranking factor that is heavily weighted by Google.
Mobile responsiveness is more important today than ever!
Globally, 52% of website visits are via mobile devices, yet according to Google, 22% of sites
are not designed to be responsive.
Unfortunately, the majority of these sites are local service providers or mom and pop
type entities.
Your website's speed is also a huge factor that matters!
Ensure you have a quality hosting provider and, if at all possible, do not purchase shared
hosting.
This will slow down your website and hurt your overall SEO score.
If you Google "Pagespeed Insights" you'll see a Google Developer link.
That page will allow you to test your site to see how you fare.
Now it's story time…
About two years ago, I wrote a blog post about ExpressionEngine vs WordPress vs Drupal vs
Joomla.
These are common content management systems used to build out websites.
I did a deep dive into the functionality of the different system.
ExpressionEngine is a CMS used by serious web developers and has an extremely high bar
of entry.
That made this an extremely niche topic to write about.
As I was writing this blog post, I knew I would get some traffic, but I assumed it wouldn't
be much since this was such a small niche.
This post was published in 2012.
For 4 years it was easily our most visited blog.
I just checked, it is now 2018, and it is still consistently in our top 10.
Why?
Creating relevant content around your niche is key to winning at SEO.
Studies show that getting your website higher in search rankings involves factors that are
rooted in relevancy, more so than ever before.
The pages that contain the most relevant content to each search are appearing higher in the
search results.
Previously, this could be manipulated through your title tags, meta tags, etc.…
Now the crawl bots are smart enough to read your content and comprehend the content.
Well, that's a wrap for this week!

Amazing Photo Ideas That Nobody Will Dare To Repeat

Micro Moments - Gaining a Customer's Instant Gratification - Duration: 4:10.
What's up Fish Fans!
My name is Marcus.
You're watching Marketing Madness, the Blue Fish vlog!
Our goal is to address common questions that business owners may have about marketing,
sales, and business in general.
This week we're going to take a look at Micro-Moments.
In a previous episode, we dove into what a Micro-Moment
is.
As a primer for those who haven't watched that video, Micro-moments occur when people
reflexively turn to a device — increasingly a smartphone — to act on a need to learn
something, do something, discover something, watch something, or buy something.
They are intent-rich moments when decisions are made and preferences shaped.
This is straight from Lisa Gevelber, Google's VP of Marketing.
Impatience, immediate action, instant gratification, even some impulsiveness — these are just
a handful of descriptors for behavior today.
We have all been empowered and emboldened by information.
With our phones acting as supercomputers in our pockets, we can find, learn, do, and buy
whenever the need or whim strikes.
3 out of every four smartphone users are looking to search first when they have questions,
need directions, or are looking for descriptions, reviews or price checking something.
Google has put out some revealing data that helps us better understand what this shifting
consumer behavior looks like, and how it impacts business owners.
People are making on the spot decisions, and search data confirms this.
Searches involving "open now" has tripled in past two years.
When we look at some of the rising "open now" searches, we see that they represent
both impromptu decisions like "I have some spare time to get my nails done" and emergency
situations like "I just cut my finger and need a doctor".
People are searching at the exact moment they need something and are looking for places
that can meet their immediate need.
In other words, when making these on-the-spot decisions, they are more loyal to their need
than to any particular place.
The new norm is for us to be able to get products and services right away.
Services like Amazon Prime, Uber, Netflix, and iTunes have all changed our behavior.
Mobile searches related to "same day shipping" have grown over 100% since 2015, as people
are no longer willing to wait even a few days for their order.
I know that when they announced the Amazing Distribution Center here in Mobile, I was
a bit excited because it will likely mean same day shipping for those items that we
have to order online.
Looking at data, we also notice that searches for "same day shipping" peak first thing
in the morning.
Rather than running an errand on the way to work, people are turning to their devices
with the expectations that they can find a business that can help them immediately.
This might be a bit of information overload.
I bet you are wondering where to even start?
Well, I can tell you this, your consumers will vary significantly from "Planner Patty"
to "Last Minute Lex."
Regardless of how they plan, they will all expect the same thing: what they want and
when they want it.
And the brand that gives it to them WINS.
In fact, we have observed that 53% of visits are abandoned if a mobile site takes longer
than 3 seconds to load.
I mean seriously, Ain't NOBODY got time for that.
Ultimately, that means that business owners must commit to the creation of incredible
mobile experiences.
The basics—like load time—can make or break you.
Remember that "3 seconds" stat I mentioned earlier?
Now consider this — the average mobile site takes almost 22 seconds to fully load.
We've seen that for every one-second delay in site load time, conversions fall by 12%.
To test your mobile site speed, Google Pagespeed Insights and click on the first link.
Google even provides immediate recommendations to make your mobile site load quicker.

Creating a Marketing Plan - Win and Retain Paying Customers - Duration: 4:53.
What's up Fish Fans!
My name is Marcus.
You're watching Marketing Madness, the Blue Fish vlog!
Our goal is to address common questions that business owners may have about marketing,
sales, and business.
In this video we are going to dive into marketing plans.
The need for a solid business plan is understood and known by pretty much every entrepreneur.
What isn't talked about enough is the need for a marketing plan.
Your business plan outlines how your business will operate, and the marketing plan outlines
how your business will win and retain paying customers.
A good marketing plan lines out all the tools and tactics you'll use to achieve your sales
goals.
Think about this as your plan of action: what you sell, who will buy, and the strategies
to use will generate qualified leads to increase your close rate.
Let's take a closer look at a marketing plan that works:
Step 1 would be to take a look at your company's current situation.
This is called a "SWOT analysis."
SWOT stands for strengths, weaknesses, opportunities, and threats.
If you do a Google search for SWOT you'll typically find a 4 quadrant drawing that has
boxes that represent each of the items
In Step 2 you need to be able to describe your target demographic and marketing audience.
Create a simple, one-paragraph profile that describes your ideal prospect or audience.
Use as much detail as possible.
We have other videos where we go into detail, but you want to cover demographics like age,
gender, salary range, physical location, family composition, lifestyle choices, etc.
Also, ask yourself these questions: Are my customers leaders or followers?
Timid or aggressive?
Introverted or extroverted?
How often are they making purchases of my product or offering?
Are they the end user of my product or service?
This also applies if you are in the business to business market, you'll want to build
a profile according to the type of businesses you want to acquire as a customer.
Listing out things like business type, size, annual revenue, location, and so on…
No matter who your targets are, be sure to be as specific as possible when building out
a profile.
This will help optimize your marketing efforts and spending.
In Step 3 you should be able to describe your offerings creatively and tactfully.
Describe how your product or service is superior to the competition or provides better value.
If you can't describe how it is better you are trying to compete on price.
Just a quick note that it is widely known that competing on price is a race to the bottom.
All of this analysis will allow you to accurately position yourself and your products in the
market.
Positioning is a video series in itself.
In Step 4 you'll list out your marketing goals.
When creating a business plan, most businesses outline the measurement of tangible goals.
This leverages sales numbers to quantify your dollars earned or spent to earn.
The same should hold true when creating your marketing plan.
You need to set goals, develop mechanisms of measurement, and then quantify your investment.
This will help you know when your marketing is working and helps keep your marketing agency
accountable.
Step 5...
Develop a winning strategy.
Previously you identified your objective and profiled your prospects that will help you
reach your target.
Now you need to plan out exactly what strategies you will use to reach the intended prospects
and achieve your goals.
Keep in mind that you may have prospects at different stages of the sales cycle and that
needs to be reflected in your marketing.
Cold prospects will need to have a different message than warm or hot prospects.
Be sure to plan your marketing efforts keeping the sales cycle in mind.
This will be a key difference maker in progressing people through your pipeline.
To complete the strategy section, outline your primary marketing strategies and include
a variety of tactics you'll use to reach prospects at any point in your sales cycle.
For example, you may use Search Engine Marketing, Google Adwords, or Facebook Ads to reach cold
prospects.
Step 6 is the one most of you struggle with.
In step 6 you need to set the budget.
To set a budget it's often suggested that you allocate a percentage of your projected
gross sales to your annual marketing budget.
I've covered how to set a marketing budget in a previous episode.
We will make sure there is a link to that video in the description.
Watch that video after this one.
There is solid math, backed by the SBA, behind how much you should be spending every year
on marketing.
Remember, marketing is essential to growing a business.
Henry Ford is known to have said, "A man that stops marketing to save money, is like
a man that stops his watch to save time."

#34 Cast the Vision Constantly - 101 Ways to Attract More Visitors - Duration: 2:34.
(upbeat music)
- Hey, digital communicators,
I'm John Falke with Johnny Flash productions
and Amplified Impact.
And this is "101 Ways to Attract More Visitors,"
a practical guide for churches to amplify their impact
and reach their communities.
Now, let's amp it up.
Number 34, Cast the Vision Constantly.
Now, I know this might seem like a lot,
but you need to reinforce the vision of your church
over and over again so that everybody understands it,
they can repeat it, they know what it is.
And the thing is,
the church vision is often to like, church leaders,
how worship songs are to the worship band, right?
The worship band practices them,
they rehearse them, they often sing the songs, perform them
for multiple services and so the worship leaders
and the worship band tend to get tired of the songs
long before the people in the seats in your church
are starting to really get them.
And so you have to just kind of
cast the vision over and over again.
You've gotta be laser sharp on your church's vision.
Andy Stanley in his book, "Visioneering,"
says we need to state our vision simply.
This is a quote from Andy.
He says, "Vision is a preferred future, a destination.
"Vision always stands in contrast to the world as it is.
"Visioneering is a clear mental picture of what could be
"fueled by the conviction that it should be."
And the reality is that vision leaks
and so you have to constantly cast the vision over
and over again just like you need to sing the songs
over and over again so people can really start to own them,
feel comfortable enough to sing them
and like they know the songs.
So, it's gonna be long past when
the band is tired of singing the song.
That's probably just when people
are starting to become familiar with it.
And so, you wanna make sure that you're casting the vision
over and over again so that everybody at your church knows
what your church is trying to do and achieve
and then they'll be more excited about it
and be able to invite their friends
and new people will be able to
understand what your church is all about.
In the next video, I'm gonna show you how to reinforce
the vision by telling your church's origin story.
Until then, amp it up.
