Ojalå estés teniendo un lindo domingo vos, que recuerdo que tanto te pesaban.
OjalĂĄ encuentres una lectura ligera, una pelĂcula dulce, un encuentro familiar cĂĄlido,
algo que te distraiga y te haga olvidar que hoy es domingo y no estĂĄs conmigo.

Some of our favorite signs from NYC Pride Yesterday. â€ïžđ§Ąđđđđ
OKAY #answertime done! Thank you guys so much! I kept about 250 questions in my inbox and Iâll go through them in the next couple weeks whenever I have time so stay tuned! Thanks for playing!
Havenât done any personal projects in months.Â
So I made art today with this critter, @nnnicoleruggiero
IN LOVE WITH @radiomaru & @milkmannerâs SNOTGIRL!! Just finished reading vol.2 and had to draw Lottie & Caroline <3Â
Iâm a bit late, but happy Pride! đ

âAmo tomar fotos, escribir, amo la lluvia, el olor a tierra mojada, amo escuchar mĂșsica y cantar como loca, amo ser feliz y amo mis ratos de tristeza.â

Hey, hola a todos, hace tiempo que no hago fotomontajes, y el otro dĂa vi unas fotos con Ă©ste estilo y quise intentarlo. Creo que no quedĂł tan mal, espero os guste y no olvides dejar tu corazĂłn que me ĂĄnima bastante. Y ahora sĂłlo falta un nombre Ă©pico para la foto: âCosmic Dancersâ. . . .

Y cada estrella se apagĂł, necesitaban de ti para brillar

Eres perfecta tal y como eres. No me importa si tienes lunares, pecas o algĂșn, barrito; me da igual si mides 1.60 o 1.75; quĂ© mĂĄs da si no tienes los cenos que siempre soñaste; y crĂ©eme que no me importa si no eres talla 0; eres perfecta sin maquillaje, sin tacones, y sin ropa ajustada o vestidos caros. Eres la chica mĂĄs perfecta y hermosa del universo si y solo si eres tu misma. Tus acciones son las que te hacen perfecta⊠y son la razĂłn por la que me enamorĂ© de tiâŠ

He llegado a un punto en el que ya no odio a nadie, simplemente no me importan.

Reinventing the Wheel
Planning a trip to the Moon? Mars? Youâre going to need good tiresâŠ
Exploration requires mobility. And whether youâre on Earth or as far away as the Moon or Mars, you need good tires to get your vehicle from one place to another. Our decades-long work developing tires for space exploration has led to new game-changing designs and materials. Yes, weâre reinventing the wheelâhereâs why.
Wheels on the Moon
Early tire designs were focused on moving hardware and astronauts across the lunar surface. The last NASA vehicle to visit the Moon was the Lunar Roving Vehicle during our Apollo missions. The vehicle used four large flexible wire mesh wheels with stiff inner frames. We used these Apollo era tires as the inspiration for new designs using newer materials and technology to better function on a lunar surface.
Up springs a new idea
During the mid-2000s, we worked with industry partner Goodyear to develop the Spring Tire, an airless compliant tire that consists of several hundred coiled steel wires woven into a flexible mesh, giving the tires the ability to support high loads while also conforming to the terrain. The Spring Tire has been proven to generate very good traction and durability in soft sand and on rocks.
Spring Tires for Mars
A little over a year after the Mars Curiosity Rover landed on Mars, engineers began to notice significant wheel damage in 2013 due to the unexpectedly harsh terrain. Thatâs when engineers began developing new Spring Tire prototypes to determine if they would be a new and better solution for exploration rovers on Mars.
In order for Spring Tires to go the distance on Martian terrain, new materials were required. Enter nickel titanium, a shape memory alloy with amazing capabilities that allow the tire to deform down to the axle and return to its original shape.
These tires can take a lickinâ
After building the shape memory alloy tire, Glenn engineers sent it to the Jet Propulsion Laboratoryâs Mars Life Test Facility. It performed impressively on the punishing track.
Why reinvent the wheel? Itâs worth it.
New, high performing tires would allow lunar and Mars rovers to explore greater regions of the surface than currently possible. They conform to the terrain and do not sink as much as rigid wheels, allowing them to carry heavier payloads for the same given mass and volume. Also, because they absorb energy from impacts at moderate to high speeds, there is potential for use on crewed exploration vehicles which are expected to move at speeds significantly higher than the current Mars rovers.
Airless tires on Earth
Maybe. Recently, engineers and materials scientists have been testing a spinoff tire version that would work on cars and trucks on Earth. Stay tuned as we continue to push the boundaries on traditional concepts for exploring our world and beyond. Â
