Celestial Send-off

by Summer Ash

 

Yesterday morning, the European Space Agency's Rosetta Mission was given a fond farewell as it performed the final maneuver of its programmed life - a controlled descent onto the surface of Comet 67P/Churyumov-Gerasimenko. I'm still consoling myself on the loss by cozying up on my couch in my Le Petite Prince sweater which is one of my most treasured possession in the world.


 

Rosetta launched in 2004, but didn't fully enter our hearts and minds when it rendezvoused with its target in mid-2014 and began sending back some of the most incredible images of this strangely beautiful rocky interloper. 

Browsing through ESA's Rosetta gallery reminds me just what an amazing time we live in. Humans banded together to create the dream, the technology, and the means to not only build and launch a spacecraft to a comet, but one that could orbit it, send down a lander, and then later descend to the surface itself.

Every single image is worth contemplating in detail if you have a quite moment, but here are just a few of my favorites.

 

October 19, 2014: As Rosetta approached the comet in the summer of 2014, scientists saw the comet had a very irregular shape, instead of one lumpy body, it looked more like two stuck together. In fact, the closer Rosetta got, the increased resolution in images revealed it to be shaped like a rubber duck. This image is looking from the "head" of the duck towards the "body." (Credit: ESA/Rosetta/NavCam – CC BY-SA IGO 3.0)

 

January 22, 2015: Comet 67P from a distance of 27.9 km above the surface looking at the "neck" area of the duck. The Hathor cliffs are to the left and the Hapi region strewn with boulders are just right of center. (Credit: ESA/Rosetta/Navcam – CC BY-SA IGO 3.0)

 

July 26, 2015: When Rosetta first reached Comet 67P, it was far enough away from the Sun that it wasn't yet "active". But as it continued toward the inner solar system, the Sun's heat caused the ices on the comet to warm and sublimate (go directly from solid to gas). This activity is what gives comet's their characteristic comas and tails. Comet 67P was too small to produce a large observable tail in the popular sense, but Rosetta go a great look at its many outgassing events.

September 30, 2016: Rosetta took a few last photos during its final approach. This is from roughly 16 km above the surface, captured overnight (at least for this New Yorker). (Credit: ESA/Rosetta/MPS for OSIRIS Team MPS/UPD/LAM/IAA/SSO/INTA/UPM/DASP/IDA)

There's a sign at NASA's Jet Propulsion Laboratory that reads "Dare Mighty Things". I always think of that when celebrating amazing feats like Rosetta. Go big or go home. Rosetta went big and now its at rest in its new home, riding through the Solar System on what is probably the best roller coaster ever.

A Universe of Love

by Summer Ash

February is branded as heart month by corporations, but I say we should feel the beat all year long. 

I have a complicated relationship with my heart to say the least, but if anything, it's made me realize the importance of friendship, love, and appreciating the Universe on a daily basis. So on this last day of February, and a bonus one at that, I thought I would share some of my favorite celestial symbols of love. 

The photo at the top of this post is of the surface of Mars, taken by the Mars Reconnaissance Orbiter (MRO) in 2009. Launched by NASA in 2005, MRO had a two-year primary mission to study the history of water on Mars. Now almost ten years later, it continues to function, still taking data while also assisting in relaying communication from other satellites and rovers on the Red Planet. 

Our other planetary neighbor, Venus, is of course named after the goddess of love herself. Venus is practically an Earth-twin in size, but an anti-twin in everything else. This image is a composite of radar data taken by the Magellan spacecraft NASA sent to Venus in 1989. The planet itself is shrouded in thick cloud layers, but NASA was able to make this image with radio waves that penetrate the atmosphere and bounce off the planet's surface, giving us a picture of the topography. While on Venus, this dense atmosphere is toxic to life, from here on Earth, it's what allows Venus to shine so bright in our morning and evening skies - and perhaps inspire our imaginations from time to time. 

Eros is a member of the asteroid belt, orbiting the Sun in an orbit similar to Mars, sometime further and sometimes closer. Fittingly, it's a member of the Amor group of asteroids. In 2000 NASA's Near Earth Asteroid Rendezvous (NEAR Shoemaker) mission was the first spacecraft to visit Eros and send back high resolution images like this one. Even more incredible is the fact that NEAR Shoemaker successfully landed on the asteroid's surface at the end of its mission life in February of 2001, just over fifteen years ago today. 

Hopefully this image needs no introduction, but if Pluto hadn't captured your heart before, I hope this picture seals the deal. Less than eight months ago, NASA's New Horizons spacecraft arrived at Pluto and snapped this phenomenal image - our first ever glimpse of this distant world. The heart shaped feature (aka Sputnik Planum) became an instant symbol of our love of exploration and discovery. 

Lastly, moving out into the galaxy, I leave you with these nebulae colloquially called Heart and Soul. Located over 6,000 light years away from us, these regions of gas and dust, called nebulae, are where are stars are actively being formed (or at least they were 6,000 years ago!). This image was taken with NASA's Wide-field Infrared Survey Explorer (WISE) which was launched into Earth orbit in 2009. WISE uses infrared light to detect emission from dust, asteroids, brown dwarfs, stars and galaxies. It captured the glow of these striking regions, IC 1848 (aka Soul Nebula) on the right and IC 1805 (aka Heart nebula) on the left, in 2010. I think it's safe to say, it also captured my heart for now and evermore. 

I hope you'll take this opportunity to look around you and realize that love is everywhere, here on Earth and throughout the Universe, not only during "heart month" but everyday.

Blood Moon

by Celine Semaan Vernon

I woke up today expecting that my stress might have vanished, as I have read that the Lunar Eclipse will be bringing us a lot of change. 

The Universe sent me this note today:


When fear speaks, celine, it's always wrong.

Game on,
The Universe

 

We are very excited to announce that we have refilled our stock for your favorite prints! Hurry before we run out again! It takes a lot of time to make them. Maybe that is why we are called Slow Factory, as we are slowly orbiting around the Earth, we also support the slow fashion movement, the slow everything movement as a matter of fact, and we are working towards a sustainable, environmentally friendly process that will allow us to grow very very slowly.

Back in stock!
