Chemical Space Gardens
You know that colorful crystal garden you grew as a kid?
Yeah, we do that in space now.Â
Chemical Gardens, a new investigation aboard the International Space Station takes a classic science experiment to space with the hope of improving our understanding of gravityâs impact on their structural formation.
Here on Earth, chemical gardens are most often used to teach students about things like chemical reactions.
Chemical gardens form when dissolvable metal salts are placed in an aqueous solution containing anions such as silicate, borate, phosphate, or carbonate.
Delivered to the space station aboard SpaceXâS CRS-15 cargo mission, the samples for this experiment will be processed by crew members and grown throughout Expedition 56 before returning to Earth.
Results from this investigation could provide a better understanding of cement science and improvements to biomaterial devices used for scaffolding, for use both in space and on Earth.Â
Follow the growth of the chemical garden and the hundreds of other investigations constantly orbiting above you by following @ISS_Research on Twitter.

gentle reminder
i know itâs hard, but your peace is more important than trying to figure out why something happened the way it did - try your best to breathe deep, let go, and focus on right now; you canât change the past, but you can make beautiful moments now instead of letting them pass by
âI advise you to stop sharing your dreams with people who try to hold you back, even if theyâre your parents. Because, if youâre the kind of person who senses thereâs something out there for you beyond whatever it is youâre expected to do - if you want to be EXTRA-ordinary - you will not get there by hanging around a bunch of people who tell you youâre not extraordinary. Instead, you will probably become as ordinary as they expect you to be.â

Solar System 10 Things: Two Years of Juno at Jupiter
Our Juno mission arrived at the King of Planets in July 2016. The intrepid robotic explorer has been revealing Jupiterâs secrets ever since.Â
Here are 10 historic Juno mission highlights:
1. Arrival at a Colossus
After an odyssey of almost five years and 1.7 billion miles (2.7 billion kilometers), our Juno spacecraft fired its main engine to enter orbit around Jupiter on July 4, 2016. Juno, with its suite of nine science instruments, was the first spacecraft to orbit the giant planet since the Galileo mission in the 1990s. It would be the first mission to make repeated excursions close to the cloud tops, deep inside the planetâs powerful radiation belts.
2. Science, Meet Art
Juno carries a color camera called JunoCam. In a remarkable first for a deep space mission, the Juno team reached out to the general public not only to help plan which pictures JunoCam would take, but also to process and enhance the resulting visual data. The results include some of the most beautiful images in the history of space exploration.
3. A Whole New Jupiter
It didnât take long for Junoâand the science teams who hungrily consumed the data it sent homeâto turn theories about how Jupiter works inside out. Among the early findings: Jupiterâs poles are covered in Earth-sized swirling storms that are densely clustered and rubbing together. Jupiterâs iconic belts and zones were surprising, with the belt near the equator penetrating far beneath the clouds, and the belts and zones at other latitudes seeming to evolve to other structures below the surface.
4. The Ultimate Classroom
The Goldstone Apple Valley Radio Telescope (GAVRT) project, a collaboration among NASA, JPL and the Lewis Center for Educational Research, lets students do real science with a large radio telescope. GAVRT data includes Jupiter observations relevant to Juno, and Juno scientists collaborate with the students and their teachers.
5. Spotting the Spot
Measuring in at 10,159 miles (16,350 kilometers) in width (as of April 3, 2017) Jupiterâs Great Red Spot is 1.3 times as wide as Earth. The storm has been monitored since 1830 and has possibly existed for more than 350 years. In modern times, the Great Red Spot has appeared to be shrinking. In July 2017, Juno passed directly over the spot, and JunoCam images revealed a tangle of dark, veinous clouds weaving their way through a massive crimson oval.
âFor hundreds of years scientists have been observing, wondering and theorizing about Jupiterâs Great Red Spot,â said Scott Bolton, Juno principal investigator from the Southwest Research Institute in San Antonio. âNow we have the best pictures ever of this iconic storm. It will take us some time to analyze all the data from not only JunoCam, but Junoâs eight science instruments, to shed some new light on the past, present and future of the Great Red Spot.â
6. Beauty Runs Deep
Data collected by the Juno spacecraft during its first pass over Jupiterâs Great Red Spot in July 2017 indicate that this iconic feature penetrates well below the clouds. The solar systemâs most famous storm appears to have roots that penetrate about 200 miles (300 kilometers) into the planetâs atmosphere.
7. Powerful Auroras, Powerful Mysteries
Scientists on the Juno mission observed massive amounts of energy swirling over Jupiterâs polar regions that contribute to the giant planetâs powerful auroras â only not in ways the researchers expected. Examining data collected by the ultraviolet spectrograph and energetic-particle detector instruments aboard Juno, scientists observed signatures of powerful electric potentials, aligned with Jupiterâs magnetic field, that accelerate electrons toward the Jovian atmosphere at energies up to 400,000 electron volts. This is 10 to 30 times higher than the largest such auroral potentials observed at Earth.Â
Jupiter has the most powerful auroras in the solar system, so the team was not surprised that electric potentials play a role in their generation. What puzzled the researchers is that despite the magnitudes of these potentials at Jupiter, they are observed only sometimes and are not the source of the most intense auroras, as they are at Earth.
8. Heat from Within
Juno scientists shared a 3D infrared movie depicting densely packed cyclones and anticyclones that permeate the planetâs polar regions, and the first detailed view of a dynamo, or engine, powering the magnetic field for any planet beyond Earth (video above). Juno mission scientists took data collected by the spacecraftâs Jovian InfraRed Auroral Mapper (JIRAM) instrument and generated a 3D fly-around of the Jovian worldâs north pole.Â
Imaging in the infrared part of the spectrum, JIRAM captures light emerging from deep inside Jupiter equally well, night or day. The instrument probes the weather layer down to 30 to 45 miles (50 to 70 kilometers) below Jupiterâs cloud tops.
9. A Highly Charged Atmosphere
Powerful bolts of lightning light up Jupiterâs clouds. In some ways its lightning is just like what weâre used to on Earth. In other ways,itâs very different. For example, most of Earthâs lightning strikes near the equator; on Jupiter, itâs mostly around the poles.
10. Extra Innings
In June, we approved an update to Junoâs science operations until July 2021. This provides for an additional 41 months in orbit around. Juno is in 53-day orbits rather than 14-day orbits as initially planned because of a concern about valves on the spacecraftâs fuel system. This longer orbit means that it will take more time to collect the needed science data, but an independent panel of experts confirmed that Juno is on track to achieve its science objectives and is already returning spectacular results. The spacecraft and all its instruments are healthy and operating nominally. â

Thereâs new evidence to support a decades-old strategy for preventing the tick bites that lead to all sorts of nasty diseases, including Lyme disease and Rocky Mountain spotted fever.
The remedy involves spraying your clothing with permethrin â a pesticide thatâs chemically similar to extracts of the flowering chrysanthemum plant.
Back in the 1980s, the U.S. military conducted several tests on a synthetic version of the plant-derived pesticide. When it was shown to be effective in preventing the bites of insects and ticks, the military began to purchase uniforms for soldiers that are factory-treated with permethrin.
Now, many outdoor enthusiasts are converts, too.
