Celebrating 17 Years of NASA’s ‘Little Earth Satellite That Could’

The satellite was little— the size of a small refrigerator; it was only supposed to last one year and constructed and operated on a shoestring budget — yet it persisted.

After 17 years of operation, more than 1,500 research papers generated and 180,000 images captured, one of NASA’s pathfinder Earth satellites for testing new satellite technologies and concepts comes to an end on March 30, 2017. The Earth Observing-1 (EO-1) satellite will be powered off on that date but will not enter Earth’s atmosphere until 2056. 

“The Earth Observing-1 satellite is like The Little Engine That Could,” said Betsy Middleton, project scientist for the satellite at NASA’s Goddard Space Flight Center in Greenbelt, Maryland. 

To celebrate the mission, we’re highlighting some of EO-1’s notable contributions to scientific research, spaceflight advancements and society. 

Scientists Learn More About Earth in Fine Detail

EO-1 carried the Advanced Land Imager that improved observations of forest cover, crops, coastal waters and small particles in the air known as aerosols. These improvements allowed researchers to identify smaller features on a local scale such as floods and landslides, which were especially useful for disaster support. 

On the night of Sept. 6, 2014, EO-1’s Hyperion observed the ongoing eruption at Holuhraun, Iceland as shown in the above image. Partially covered by clouds, this scene shows the extent of the lava flows that had been erupting.

EO-1’s other key instrument Hyperion provided an even greater level of detail in measuring the chemical constituents of Earth’s surface— akin to going from a black and white television of the 1940s to the high-definition color televisions of today. Hyperion’s level of sophistication doesn’t just show that plants are present, but can actually differentiate between corn, sorghum and many other species and ecosystems. Scientists and forest managers used these data, for instance, to explore remote terrain or to take stock of smoke and other chemical constituents during volcanic eruptions, and how they change through time.  

Crowdsourced Satellite Images of Disasters   

EO-1 was one of the first satellites to capture the scene after the World Trade Center attacks (pictured above) and the flooding in New Orleans after Hurricane Katrina. EO-1 also observed the toxic sludge in western Hungary in October 2010 and a large methane leak in southern California in October 2015. All of these scenes, which EO-1 provided quick, high-quality satellite imagery of the event, were covered in major news outlets. All of these scenes were also captured because of user requests. EO-1 had the capability of being user-driven, meaning the public could submit a request to the team for where they wanted the satellite to gather data along its fixed orbits.

 Artificial Intelligence Enables More Efficient Satellite Collaboration

EO-1 was among the first satellites to be programmed with a form of artificial intelligence software, allowing the satellite to make decisions based on the data it collects. For instance, if a scientist commanded EO-1 to take a picture of an erupting volcano, the software could decide to automatically take a follow-up image the next time it passed overhead. The Autonomous Sciencecraft Experiment software was developed by NASA’s Jet Propulsion Laboratory in Pasadena, California, and was uploaded to EO-1 three years after it launched. 

This image of Nassau Bahamas was taken by EO-1’s Advanced Land Imager on Oct 8, 2016, shortly after Hurricane Matthew hit. European, Japanese, Canadian, and Italian Space Agency members of the international coalition Committee on Earth Observation Satellites used their respective satellites to take images over the Caribbean islands and the U.S. Southeast coastline during Hurricane Matthew. Images were used to make flood maps in response to requests from disaster management agencies in Haiti, Dominican Republic, St. Martin, Bahamas, and the U.S. Federal Emergency Management Agency.

The artificial intelligence software also allows a group of satellites and ground sensors to communicate and coordinate with one another with no manual prompting. Called a “sensor web”, if a satellite viewed an interesting scene, it could alert other satellites on the network to collect data during their passes over the same area. Together, they more quickly observe and downlink data from the scene than waiting for human orders. NASA’s SensorWeb software reduces the wait time for data from weeks to days or hours, which is especially helpful for emergency responders. 

Laying the Foundation for ‘Formation Flying’

This animation shows the Rodeo-Chediski fire on July 7, 2002, that were taken one minute apart by Landsat 7 (burned areas in red) and EO-1 (burned areas in purple). This precision formation flying allowed EO-1 to directly compare the data and performance from its land imager and the Landsat 7 ETM+. EO-1’s most important technology goal was to test ALI for future Landsat satellites, which was accomplished on Landsat 8. Credit: NASA’s Goddard Space Flight Center

EO-1 was a pioneer in precision “formation flying” that kept it orbiting Earth exactly one minute behind the Landsat 7 satellite, already in orbit. Before EO-1, no satellite had flown that close to another satellite in the same orbit. EO-1 used formation flying to do a side-by-side comparison of its onboard ALI with Landsat 7’s operational imager to compare the products from the two imagers. Today, many satellites that measure different characteristics of Earth, including the five satellites in NASA’s A Train, are positioned within seconds to minutes of one another to make observations on the surface near-simultaneously.

I'm saying this from the perspective of a shipper I guess but looking at all these Sheith moments got me thinking.. Would it be possible that the creators themselves are actually planning for them to be canon at some point? But because of some complications..(not gonna name it) they decided to scrap it off? Do you think this is possible? Although Keith telling Shiro he is like a brother to him kinda made me sad? lol I have got so many questions so I can't wait to see more of this amazing series!

Hi anon! The thing is, writing and animation for shows like this are done way in advance. When season 1 came out, I imagine the plot up until seasons 3 or 4 was already set in stone. And Voltron, like most shows, works off a “TV Bible” that had all the major plot points outlined right when the series was first pitched so,, once you plan things out like that I think it’s difficult to make big changes to characters’ relationships.   

I think the writers have also made it clear that they are going to go ahead with their narrative rather than catering to popular fannon, particularly when they’ve told certain fans they don’t agree with their mentality at all. Even with things like how they mentioned Allura was a teenager like all the other paladins, a lot of people didn’t headcannon that, but the writers stood by it. It’s their own story after all, and I don’t see why they should change it. As for sheith, we know the writers have outright told people that harassing shippers isn’t okay and they’re completely against it. 

There are also plenty of writers, animators, and VAs who have liked clearly romantic sheith fanart, cosplay, or pro-sheith posts (and gotten backlash for it). So we know they’re certainly not opposed to shipping it. And I mean, whether it’s romantic or not, we know that the cast certainly seems invested in their dynamic. The fact that their relationship and character development is by far the most fleshed out is certainly apparent. Here’s also some stuff staff has drawn that shows they at least like Shiro and Keith’s bond: 

So anyway, despite how the fandom can be, I don’t think it would necessarily deter the writers or dissuade them from following through with major writing decisions. And given how supportive the staff has been of sheith, I don’t think they would suddenly just abandon whatever plans they had for their character development together. Under the hypothetical that they did make sheith canon, I think they would just maybe adjust how they went about it so that the fandom could kind of like, ease into it, and hopefully not be too mad about it. Though I have no doubt people would still harass the staff if sheith happened, which just…makes me feel really bad to be honest…

On the BOM line though anon, I don’t think it goes against sheith at all and here’s why:

BIG HERO 6 X JURASSIC WORLD AU, PART 3 of 6

Okay so this part is admittedly slightly filler, but since we were all about Hiro last part, it makes sense to focus on her brother for part 3?

I have many alternative titles for this part, including “Fandom Treats Tadashi Too Nice and Forgets He Did a Really Stupid Thing So Let’s Rub It In,” “How the F*** Do You Draw Chris Pratt,” “OOH LOOK RAPTORS I LOVE RAPTORS,” and “I Can’t Draw Chris Pratt.”

Also, there was this marvelous scene in the Jurassic World deleted scenes in the DVD that was released Oct. 1st. Mind you, I had this mostly drawn and finished in June/July. It was kind of amazing how well it fit with this scene. I’ll put screenshots (with my camera b/c iTunes won’t let me take actual screenshots *sigh*) behind a cut at the end of this, but look at this marvelousness that is Owen, Claire, and Pile o’ Dino Poo:

Ahem.

And reminder, I will not be answering questions about the content of this AU until after all 6 parts have been posted. Please look forward to the other parts! (´▽`) And if things click into place faster for you, don’t spoil it for others~!

                        <<PART 1>>       <<PART 2>>       <<PART 4>>

More on this AU and other links will be added to the MASTERPOST found here.

U.S. FCC votes 2-1 to advance repeal of Obama-era internet rules
The U.S. Federal Communications Commission voted 2-1 on Thursday to advance a Republican plan to reverse the Obama administration's 2015 "net neutrality" order.

The FCC just voted in favor of Pai’s plan to dismantle net neutrality, but this isn’t the end. This is just the first step. There will be a few months in which the public may comment on his plan, which is hilariously called “Restoring Internet Freedom”. Please, please, please comment and let the FCC know how much you oppose this plan.
