Photographing Planets With The Roman Space Telescope

Kate Rubins’ Space Station Science Scrapbook

As a child, Kate Rubins dreamed of being an astronaut and a scientist. During the past four months aboard the International Space Station, that dream came full circle. She became the first person to sequence DNA in space, among other research during her recent mission, adding to her already impressive experience. She holds a doctorate in molecular biology, and previously led a lab of 14 researchers studying viruses, including Ebola.

Here’s a look back at Rubins in her element, conducting research aboard your orbiting laboratory.

Kate inside Destiny, the U.S. Laboratory Module

The U.S. national laboratory, called Destiny, is the primary research laboratory for U.S. payloads, supporting a wide range of experiments and studies contributing to health, safety, and quality of life for people all over the world. 

Destiny houses the Microgravity Science Glovebox (MSG), in which Kate worked on the Heart Cells experiment.

Swabbing for Surface Samples

Microbes that can cause illness could present problems for current and future long duration space missions. 

Understanding what microbe communities thrive in space habitats could help researchers design antimicrobial technology. Here, Kate is sampling various surfaces of the Kibo module for the Microbe-IV investigation.

Culturing Beating Heart Cells in Space

The Heart Cells investigation uses human skin cells that are induced to become stem cells, which can then differentiate into any type of cell. 

Researchers forced the stem cells to grow into human heart cells, which Rubins cultured aboard the space station for one month.

Rubins described seeing the heart cells beat for the first time as “pretty amazing. First of all, there’s a few things that have made me gasp out loud up on board the [space] station. Seeing the planet was one of them, but I gotta say, getting these cells in focus and watching heart cells actually beat has been another pretty big one.”

Innovative Applied Research Experiment from Eli Lilly

The Hard to Wet Surfaces investigation from Eli Lilly, and sponsored by the Center for the Advancement of Science in Space (CASIS), looks at liquid-solid interactions and how certain pharmaceuticals dissolve, which may lead to more potent and effective medicines in space and on Earth. 

Rubins set up vials into which she injected buffer solutions and then set up photography to track how tablets dissolved in the solution in microgravity.

Capturing Dragon

Rubins assisted in the capture of the SpaceX Dragon cargo spacecraft in July. The ninth SpaceX resupply mission delivered more than two thousand pounds of science to the space station. 

Biological samples and additional research were returned on the Dragon spacecraft more than a month later.  

Sliding Science Outside the Station

Science doesn’t just happen inside the space station. External Earth and space science hardware platforms are located at various places along the outside of the orbiting laboratory. 

The Japanese Experiment Module airlock can be used to access the JEM Exposed Facility. Rubins installed the JEM ORU Transfer Interface (JOTI) on the JEM airlock sliding table used to install investigations on the exterior of the orbiting laboratory.

Installing Optical Diagnostic Instrument in the MSG

Rubins installed an optical diagnostic instrument in the Microgravity Science Glovebox (MSG) as part of the Selective Optical Diagnostics Instrument (SODI-DCMIX) investigation. Molecules in fluids and gases constantly move and collide. 

When temperature differences cause that movement, called the Soret effect, scientists can track it by measuring changes in the temperature and movement of mass in the absence of gravity. Because the Soret effect occurs in underground oil reservoirs, the results of this investigation could help us better understand such reservoirs.

The Sequencing of DNA in Space

When Rubins’ expedition began, DNA had never been sequenced in space. Within just a few weeks, she and the Biomolecule Sequencer team had sequenced their one billionth “base” – the unit of DNA - aboard the orbiting laboratory. 

The Biomolecule Sequencer investigation seeks to demonstrate that DNA sequencing in microgravity is possible, and adds to the suite of genomics capabilities aboard the space station.

Studying Fluidic Dynamics with SPHERES

The SPHERES-Slosh investigation examines the way liquids move inside containers in a microgravity environment. The phenomena and mechanics associated with such liquid movement are still not well understood and are very different than our common experiences with a cup of coffee on Earth.

Rockets deliver satellites to space using liquid fuels as a power source, and this investigation plans to improve our understanding of how propellants within rockets behave in order to increase the safety and efficiency of future vehicle designs. Rubins conducted a series of SPHERES-Slosh runs during her mission.

Retrieving Science Samples for Their Return to Earth

Precious science samples like blood, urine and saliva are collected from crew members throughout their missions aboard the orbiting laboratory. 

They are stored in the Minus Eighty-Degree Laboratory Freezer for ISS (MELFI) until they are ready to return to Earth aboard a Soyuz or SpaceX Dragon vehicle.

Measuring Gene Expression of Biological Specimens in Space

Our WetLab-2 hardware system is bringing to the space station the technology to measure gene expression of biological specimens in space, and to transmit the results to researchers on Earth at the speed of light. 

Rubins ran several WetLab-2 RNA SmartCycler sessions during her mission.

Studying the First Expandable Habitat Module on the Space Station

The Bigelow Expandable Activity Module (BEAM) is the first expandable habitat to be installed on the space station. It was expanded on May 28, 2016. 

Expandable habitats are designed to take up less room on a spacecraft, but provide greater volume for living and working in space once expanded. Rubins conducted several evaluations inside BEAM, including air and surface sampling.

Better Breathing in Space and Back on Earth

Airway Monitoring, an investigation from ESA (the European Space Agency), uses the U.S. airlock as a hypobaric facility for performing science. Utilizing the U.S. airlock allows unique opportunities for the study of gravity, ambient pressure interactions, and their effect on the human body. 

This investigation studies the occurrence and indicators of airway inflammation in crew members, using ultra-sensitive gas analyzers to evaluate exhaled air. This could not only help in spaceflight diagnostics, but that also hold applications on earth within diagnostics of similar conditions, for example monitoring of asthma.

Hot Science with Cool Flames

Fire behaves differently in space, where buoyant forces are removed. Studying combustion in microgravity can increase scientists’ fundamental understanding of the process, which could lead to improvement of fire detection and suppression systems in space and on Earth. 

Many combustion experiments are performed in the Combustion Integration Rack (CIR) aboard the space station. Rubins replaced two Multi-user Droplet Combustion Apparatus (MDCA) Igniter Tips as part of the CIR igniter replacement operations.

Though Rubins is back on Earth, science aboard the space station continues, and innovative investigations that seek to benefit humans on Earth and further our exploration of the solar system are ongoing. Follow @ISS_Research to keep up with the science happening aboard your orbiting laboratory.

Earth’s Land Ice by the Numbers

“At a glacial pace” used to mean moving so slowly the movement is almost imperceptible. Lately though, glaciers are moving faster. Ice on land is melting and flowing, sending water to the oceans, where it raises sea levels.

In 2018, we launched the Ice, Cloud and Land Elevation Satellite-2 (ICESat-2) to continue a global record of ice elevation. Now, the results are in. Using millions of measurements from a laser in space and quite a bit of math, researchers have confirmed that Earth is rapidly losing ice.

16 Years 

ICESat-2 was a follow-up mission to the original ICESat, which launched in 2003 and took measurements until 2009. Comparing the two records tells us how much ice sheets have lost over 16 years.

½ Inch

During those 16 years, melting ice from Antarctica and Greenland was responsible for just over a half-inch of sea level rise. When ice on land melts, it eventually finds its way to the ocean. The rapid melt at the poles is no exception.

400,000 Olympic Swimming Pools

One gigaton of ice holds enough water to fill 400,000 Olympic swimming pools. It’s also enough ice to cover Central Park in New York in more than 1,000 feet of ice.

200 Gigatons

Between 2003 and 2019, Greenland lost 200 gigatons of ice per year. That’s 80 million Olympic swimming pools reaching the ocean every year, just from Greenland alone.

118 Gigatons

During the same time period, Antarctica lost 118 gigatons of ice per year. That’s another 47 million Olympic swimming pools every year. While there has been some elevation gain in the continent’s center from increased snowfall, it’s nowhere near enough to make up for how much ice is lost to the sea from coastal glaciers.

10,000 Pulses

ICESat-2 sends out 10,000 pulses of laser light a second down to Earth’s surface and times how long it takes them to return to the satellite, down to a billionth of a second. That’s how we get such precise measurements of height and changing elevation.

These numbers confirm what scientists have been finding in most previous studies and continue a long record of data showing how Earth’s polar ice is melting. ICESat-2 is a key tool in our toolbox to track how our planet is changing.

The National Space Council

October 5 marks the first meeting of the National Space Council since 1993. But what is it and why does it matter? Let us explain by taking a trip back in history… We’ve teleported back to 1958…President Dwight Eisenhower is in office and the National Aeronautics and Space Council was created with the signing of the Space Act that year. President Eisenhower chaired the first National Aeronautics and Space Council (NASC). That council continued during the Kennedy, Johnson and Nixon Administrations during which we put an American in outer space with John Glenn in 1962 and put humans on the moon starting in 1969. That Council was disbanded in 1973.

In 1989, President George H.W. Bush’s Administration reinstated what was known as the National Space Council, which was designed to help chart national space policy and the roles of multiple federal agencies such as NASA. The Space Council disbanded again in 1993.

On June 30, 2017, President Trump signed an executive order reestablishing the National Space Council – which brings us to today. The current National Space Council will bring a unified national perspective on space policy to the Administration by coordinating the views of the civilian, commercial and national security sectors.

So now that you have a bit of the history…why does this matter?

With the Oct. 5 meeting, titled “Leading the Next Frontier: An Event with the National Space Council,” Vice President Mike Pence will convene this council and have participation from acting NASA Administrator Robert Lightfoot, as well as a number of Trump Administration cabinet members and senior officials, and aerospace industry leaders.

During the council’s first meeting, we will hear from experts who represent various parts of the space industry: Civil Space, Commercial Space and National Security Space.

You can watch the first meeting of the National Space Council starting at 10 a.m. EDT HERE.

Could Planets Like Those Imagined in Star Wars Be Real??

Look at what we’ve found so far. 

Is your favorite Star Wars planet a desert world or an ice planet or a jungle moon?

It’s possible that your favorite planet exists right here in our galaxy. Astronomers have found over 3,400 planets around other stars, called “exoplanets.”

Some of these alien worlds could be very similar to arid Tatooine, watery Scarif and even frozen Hoth, according to NASA scientists.

Find out if your planet exists in a galaxy far, far away or all around you.

Planets With Two Suns

Were you going to the Tosche station to pick up some power converters? Hold on a minute and learn about Kepler-16b, 200 light-years from Earth. It’s the first honest-to-goodness planet ever found where you could watch two suns set like Luke. George Lucas himself even blessed its nickname ‘Tatooine.’ It’s not a perfect comparison: Kepler-16b is a cold gas giant roughly the size of Saturn. But don’t worry, kid.

The best part is that Tatooine aka Kepler-16b was just the first. It has family. A LOT of family. Half the stars in our galaxy are pairs, rather than single stars like our sun. If every star has at least one planet, that’s billions of worlds with two suns. Billions! Maybe waiting for life to be found on them.

Desert Worlds

If you’re like Finn and want to know why everyone wants to go back to Jakku desert planets, get this: Star Wars may be reflecting the real universe. Desert worlds are not only a very real possibility, but we think they are probably very common. They can be hot, like the fictional Tatooine and Jakku, or cold, like Jedha in “Rogue One” or our real planet Mars.

Perhaps it’s not so weird that both Luke and Rey grew up on planets that look suspiciously like each other. If you’re scouring the universe for a place to settle, you have a good chance of finding a desert planet.

Ice Planets

There is a Hoth in our galaxy! Though not the same Hoth from “The Empire Strikes Back” (no invading Imperials, for one). The icy super-Earth reminded scientists so much of the frozen Rebel base they nicknamed it “Hoth.” The planet’s real name is OGLE 2005-BLG-390L.

Our galaxy’s Hoth is too cold to support life as we know it. But life may evolve under the ice of a different world, or a moon in our solar system.

We’re currently designing a mission to look for life under the crust of Jupiter’s icy moon Europa. We’re pretty sure ity won’t look like tauntauns, if it exists.

Forest worlds

Both the forest moon of Endor and Takodana, the home of Han Solo’s favorite cantina in “Force Awakens,” are green like our home planet. But astrobiologists think that plant life on other worlds could be red, black, or even rainbow-colored!

In August 2016, astronomers from the European Southern Observatory announced the discovery of Proxima Centauri b, a planet only four light-years away from Earth, which orbits a tiny red star.

The light from a red star, also known as an M dwarf, is dim and mostly in the infrared spectrum (as opposed to the visible spectrum we see with our sun). And that could mean plants with wildly different colors than what we’re used to seeing on Earth. Or, animals that see in the near-infrared.

And Beyond

The next few years will see the launch of a new generation of spacecraft to search for planets around other stars. TESS and the James Webb Telescope will go into space in 2018, and WFIRST in the mid-2020s. That’s one step closer to finding life.

You don’t need to visit a galaxy far, far away to find wondrous worlds. Just visit this one ... there’s plenty to see.

Why Bennu? 10 Reasons

After traveling for two years and billions of kilometers from Earth, the OSIRIS-REx probe is only a few months away from its destination: the intriguing asteroid Bennu. When it arrives in December, OSIRIS-REx will embark on a nearly two-year investigation of this clump of rock, mapping its terrain and finding a safe and fruitful site from which to collect a sample.

The spacecraft will briefly touch Bennu’s surface around July 2020 to collect at least 60 grams (equal to about 30 sugar packets) of dirt and rocks. It might collect as much as 2,000 grams, which would be the largest sample by far gathered from a space object since the Apollo Moon landings. The spacecraft will then pack the sample into a capsule and travel back to Earth, dropping the capsule into Utah's west desert in 2023, where scientists will be waiting to collect it.

This years-long quest for knowledge thrusts Bennu into the center of one of the most ambitious space missions ever attempted. But the humble rock is but one of about 780,000 known asteroids in our solar system. So why did scientists pick Bennu for this momentous investigation? Here are 10 reasons:

1. It's close to Earth

Unlike most other asteroids that circle the Sun in the asteroid belt between Mars and Jupiter, Bennu’s orbit is close in proximity to Earth's, even crossing it. The asteroid makes its closest approach to Earth every 6 years. It also circles the Sun nearly in the same plane as Earth, which made it somewhat easier to achieve the high-energy task of launching the spacecraft out of Earth's plane and into Bennu's. Still, the launch required considerable power, so OSIRIS-REx used Earth’s gravity to boost itself into Bennu’s orbital plane when it passed our planet in September 2017.

2. It's the right size

Asteroids spin on their axes just like Earth does. Small ones, with diameters of 200 meters or less, often spin very fast, up to a few revolutions per minute. This rapid spinning makes it difficult for a spacecraft to match an asteroid's velocity in order to touch down and collect samples. Even worse, the quick spinning has flung loose rocks and soil, material known as "regolith" — the stuff OSIRIS-REx is looking to collect — off the surfaces of small asteroids. Bennu’s size, in contrast, makes it approachable and rich in regolith. It has a diameter of 492 meters, which is a bit larger than the height of the Empire State Building in New York City, and rotating once every 4.3 hours.

3. It's really old

Bennu is a leftover fragment from the tumultuous formation of the solar system. Some of the mineral fragments inside Bennu could be older than the solar system. These microscopic grains of dust could be the same ones that spewed from dying stars and eventually coalesced to make the Sun and its planets nearly 4.6 billion years ago. But pieces of asteroids, called meteorites, have been falling to Earth's surface since the planet formed. So why don't scientists just study those old space rocks? Because astronomers can't tell (with very few exceptions) what kind of objects these meteorites came from, which is important context. Furthermore, these stones, that survive the violent, fiery decent to our planet's surface, get contaminated when they land in the dirt, sand, or snow. Some even get hammered by the elements, like rain and snow, for hundreds or thousands of years. Such events change the chemistry of meteorites, obscuring their ancient records.

4. It's well preserved

Bennu, on the other hand, is a time capsule from the early solar system, having been preserved in the vacuum of space. Although scientists think it broke off a larger asteroid in the asteroid belt in a catastrophic collision between about 1 and 2 billion years ago, and hurtled through space until it got locked into an orbit near Earth's, they don’t expect that these events significantly altered it.

5. It might contain clues to the origin of life

Analyzing a sample from Bennu will help planetary scientists better understand the role asteroids may have played in delivering life-forming compounds to Earth. We know from having studied Bennu through Earth- and space-based telescopes that it is a carbonaceous, or carbon-rich, asteroid. Carbon is the hinge upon which organic molecules hang. Bennu is likely rich in organic molecules, which are made of chains of carbon bonded with atoms of oxygen, hydrogen, and other elements in a chemical recipe that makes all known living things. Besides carbon, Bennu also might have another component important to life: water, which is trapped in the minerals that make up the asteroid.

6. It contains valuable materials

Besides teaching us about our cosmic past, exploring Bennu close-up will help humans plan for the future. Asteroids are rich in natural resources, such as iron and aluminum, and precious metals, such as platinum. For this reason, some companies, and even countries, are building technologies that will one day allow us to extract those materials. More importantly, asteroids like Bennu are key to future, deep-space travel. If humans can learn how to extract the abundant hydrogen and oxygen from the water locked up in an asteroid’s minerals, they could make rocket fuel. Thus, asteroids could one day serve as fuel stations for robotic or human missions to Mars and beyond. Learning how to maneuver around an object like Bennu, and about its chemical and physical properties, will help future prospectors.

7. It will help us better understand other asteroids

Astronomers have studied Bennu from Earth since it was discovered in 1999. As a result, they think they know a lot about the asteroid's physical and chemical properties. Their knowledge is based not only on looking at the asteroid, but also studying meteorites found on Earth, and filling in gaps in observable knowledge with predictions derived from theoretical models. Thanks to the detailed information that will be gleaned from OSIRIS-REx, scientists now will be able to check whether their predictions about Bennu are correct. This work will help verify or refine telescopic observations and models that attempt to reveal the nature of other asteroids in our solar system.

8. It will help us better understand a quirky solar force ...

Astronomers have calculated that Bennu’s orbit has drifted about 280 meters (0.18 miles) per year toward the Sun since it was discovered. This could be because of a phenomenon called the Yarkovsky effect, a process whereby sunlight warms one side of a small, dark asteroid and then radiates as heat off the asteroid as it rotates. The heat energy thrusts an asteroid either away from the Sun, if it has a prograde spin like Earth, which means it spins in the same direction as its orbit, or toward the Sun in the case of Bennu, which spins in the opposite direction of its orbit. OSIRIS-REx will measure the Yarkovsky effect from close-up to help scientists predict the movement of Bennu and other asteroids. Already, measurements of how this force impacted Bennu over time have revealed that it likely pushed it to our corner of the solar system from the asteroid belt.

9. ... and to keep asteroids at bay

One reason scientists are eager to predict the directions asteroids are drifting is to know when they're coming too-close-for-comfort to Earth. By taking the Yarkovsky effect into account, they’ve estimated that Bennu could pass closer to Earth than the Moon is in 2135, and possibly even closer between 2175 and 2195. Although Bennu is unlikely to hit Earth at that time, our descendants can use the data from OSIRIS-REx to determine how best to deflect any threatening asteroids that are found, perhaps even by using the Yarkovsky effect to their advantage.

10. It's a gift that will keep on giving

Samples of Bennu will return to Earth on September 24, 2023. OSIRIS-REx scientists will study a quarter of the regolith. The rest will be made available to scientists around the globe, and also saved for those not yet born, using techniques not yet invented, to answer questions not yet asked.

How had your background in the US Air Force as a flight test engineer prepare you for the challenges and demands of being an astronaut?

SpaceX Sends Super Science to Space Station!

SpaceX is scheduled to launch its Dragon spacecraft PACKED with super cool research and technology to the International Space Station June 1 from Kennedy Space Center in Florida. New solar panels, investigations that study neutron stars and even fruit flies are on the cargo list. Let’s take a look at what other bits of science are making their way to the orbiting laboratory 250 miles above the Earth…

New solar panels to test concept for more efficient power source

Solar panels generate power well, but they can be delicate and large when used to power a spacecraft or satellites. This technology demonstration is a solar panel concept that is lighter and stores more compactly for launch than the solar panels currently in use. 

Roll-Out Solar Array (ROSA) has solar cells on a flexible blanket and a framework that rolls out like a tape measure and snap into place, and could be used to power future space vehicles.  

Investigation to Study Composition of Neutron Stars

Neutron stars, the glowing cinders left behind when massive stars explode as supernovas, contain exotic states of matter that are impossible to replicate in any lab. NICER studies the makeup of these stars, and could provide new insight into their nature and super weird behavior.

Neutron stars emit X-ray radiation, enabling the NICER technology to observe and record information about its structure, dynamics and energetics. 

Experiment to Study Effect of New Drug on Bone Loss

When people and animals spend lots of space, they experience bone density loss. In-flight exercise can prevent it from getting worse, but there isn’t a therapy on Earth or in space that can restore bone that is already lost.

The Systemic Therapy of NELL-1 for osteoporosis (Rodent Research-5) investigation tests a new drug that can both rebuild bone and block further bone loss, improving health for crew members.

Research to Understand Cardiovascular Changes

Exposure to reduced gravity environments can result in cardiovascular changes such as fluid shifts, changes in total blood volume, heartbeat and heart rhythm irregularities, and diminished aerobic capacity.

The Fruit Fly Lab-02 study will use the fruit fly (Drosophila melanogaster) to better understand the underlying mechanisms responsible for the adverse effects of prolonged exposure to microgravity on the heart. Fruit flies are effective model organisms, and we don’t mean on the fashion runway. Want to see how 1,000 bottles of fruit flies were prepared to go to space? Check THIS out.

Space Life-Support Investigation

Currently, the life-support systems aboard the space station require special equipment to separate liquids and gases. This technology utilizes rotating and moving parts that, if broken or otherwise compromised, could cause contamination aboard the station. 

The Capillary Structures investigation studies a new method of water recycling and carbon dioxide removal using structures designed in specific shapes to manage fluid and gas mixtures. 

Earth-Observation Tools

Orbiting approximately 250 miles above the Earth’s surface, the space station provides pretty amazing views of the Earth. The Multiple User System for Earth Sensing (MUSES) facility hosts Earth-viewing instruments such as high-resolution digital cameras, hyperspectral imagers, and provides precision pointing and other accommodations.

This investigation can produce data that could be used for maritime domain awareness, agricultural awareness, food security, disaster response, air quality, oil and gas exploration and fire detection.

Solar System: 5 Things To Know This Week

Our solar system is huge, so let us break it down for you. Here are 5 things to know this week: 

1. You Call the Shots

This July, when the Juno mission arrives at Jupiter, it will eye the massive planet with JunoCam. What adds extra interest to this mission is that the public is invited to help Juno scientists choose which images JunoCam will take. Now is the time to get involved.

2. Dawn Delivers

We've seen several images now from the Dawn spacecraft's new, close orbit around Ceres—and they don't disappoint. Exquisitely detailed photos of the dwarf planet reveal craters, cliffs, fractures, canyons and bright spots in many locations. "Everywhere we look in these new low-altitude observations, we see amazing landforms that speak to the unique character of this most amazing world," said the mission's principal investigator.

3. Remembering the Visit to a Sideways World

Jan. 24 is the 30th anniversary of Voyager 2's Uranus flyby. The seventh planet is notable for the extreme tilt of its axis, its lacy ring system and its large family of moons—10 of which were discovered thanks to Voyager's close encounter. In fact, we learned much of what we know about the Uranian system during those few days in 1986.

4. A Decade in the Deep

The New Horizons spacecraft left Earth 10 years ago this week. Its long voyage into deep space is, even now, transforming our understanding of the outer solar system. New data and pictures from the Pluto flyby are still streaming down from the spacecraft. Pending the approval of an extended mission, New Horizons is en route to a 2019 rendezvous with a small, unexplored world in the distant Kuiper Belt.

5. Power at a Distance

Space exploration helped drive the development of practical solar cells, and now solar power has gone farther than ever before. Last week, NASA's Juno spacecraft broke the record for the most distant solar-powered craft when it passed a distance of 493 million miles (793 million kilometers) from the sun. The four-ton Juno spacecraft draws energy from three 30-foot-long (9-meter) solar arrays festooned with 18,698 individual cells.

Solar System: Things to Know This Week

Our solar system is huge, let us break it down for you. Here are a few things to know this week:

1. Juno Eyes on Jupiter

After a journey of more than five years, the Juno spacecraft is ready for its detailed look at Jupiter—arrival date: July 4. Using Eyes on the Solar System and data from the Juno flight team, you can take a virtual ride onboard the spacecraft in the "Eyes on Juno" simulation.

2. Taking a Spacecraft for a Spin

Preparations for the launch of the OSIRIS-REx asteroid mission are spinning up, literally. Here, the spacecraft can be seen rotating on a spin table during a weight and center of gravity verification test at our Kennedy Space Center. Liftoff is scheduled for Sept. 8. This spacecraft will travel to a near-Earth asteroid called Bennu and bring a small sample back to Earth for study.

3. Long-Range (Or at Least Long-Distance) Weather Report

Our Mars Reconnaissance Orbiter acquires a global view of the red planet and its weather every day. Last week, dust storms continued along the south polar ice cap edge. Northern portions of Sirenum, Solis, and Noachis also experienced some local dust-lifting activity. A large dust storm propagated eastward over the plains of Arcadia at the beginning of the week, but subsided just a few days later over Acidalia.

4. Hello from the Dark Side

The New Horizons spacecraft took this stunning image of Pluto only a few minutes after closest approach in July 2015, with the sun on the other side of Pluto. Sunlight filters through Pluto's complex atmospheric haze layers. Looking back at Pluto with images like this gives New Horizons scientists information about Pluto's hazes and surface properties that they can't get from images taken on approach.

5. A Titanic Encounter

On June 7, our Cassini orbiter will fly very close by Saturn's giant, haze-shrouded moon Titan. Among the targets of its observations will be the edge of the vortex that swirls in Titan's thick atmosphere near its south pole.
