Capturing Space Stories, One Click at a Time!

It’s World Photography Day!

To celebrate the occasion, we’re sharing photos from our photographers that chronicle what's making news across the agency - from launches and landings to important science announcements to images taken from the vantage point of space.

Take a look!

A Closer View of the Moon 

Posted to Twitter by European Space Agency astronaut Alexander Gerst, this image shows our planet's Moon as seen from the International Space Station. As he said in the tweet, "By orbiting the Earth almost 16 times per day, the #ISS crew travel the distance to the Moon and back – every day. #Horizons"

The International Space Station is the world's only orbital laboratory. An international partnership of space agencies provides and operates the elements of the station. The principals are the space agencies of the United States, Russia, Europe, Japan and Canada.

Solar System: 10 Things to Know

All About Ice

1. Earth's Changing Cryosphere

This year, we will launch two satellite missions that will increase our understanding of Earth's frozen reaches. Snow, ice sheets, glaciers, sea ice and permafrost, known as the cryosphere, act as Earth's thermostat and deep freeze, regulating temperatures by reflecting heat from the Sun and storing most of our fresh water.

2. GRACE-FO: Building on a Legacy and Forging Ahead

The next Earth science satellites set to launch are twins! The identical satellites of the GRACE Follow-On mission will build on the legacy of their predecessor GRACE by also tracking the ever-changing movement of water around our planet, including Earth's frozen regions. GRACE-FO, a partnership between us and the German Research Center for Geosciences (GFZ), will provide critical information about how the Greenland and Antarctic ice sheets are changing. GRACE-FO, working together, will measure the distance between the two satellites to within 1 micron (much less than the width of a human hair) to determine the mass below. 

Greenland has been losing about 280 gigatons of ice per year on average, and Antarctica has lost almost 120 gigatons a year with indications that both melt rates are increasing. A single gigaton of water would fill about 400,000 Olympic-sized swimming pools; each gigaton represents a billion tons of water.

3. ICESat-2: 10,000 Laser Pulses a Second

In September, we will launch ICESat-2, which uses a laser instrument to precisely measure the changing elevation of ice around the world, allowing scientists to see whether ice sheets and glaciers are accumulating snow and ice or getting thinner over time. ICESat-2 will also make critical measurements of the thickness of sea ice from space. Its laser instrument sends 10,000 pulses per second to the surface and will measure the photons' return trip to satellite. The trip from ICESat-2 to Earth and back takes about 3.3 milliseconds.

4. Seeing Less Sea Ice

Summertime sea ice in the Arctic Ocean now routinely covers about 40% less area than it did in the late 1970s, when continuous satellite observations began. This kind of significant change could increase the rate of warming already in progress and affect global weather patterns.

5. The Snow We Drink

In the western United States, 1 in 6 people rely on snowpack for water. Our field campaigns such as the Airborne Snow Observatory and SnowEx seek to better understand how much water is held in Earth's snow cover, and how we could ultimately measure this comprehensively from space.

6. Hidden in the Ground

Permafrost - permanently frozen ground in the Arctic that contains stores of heat-trapping gases such as methane and carbon dioxide - is thawing at faster rates than previously observed. Recent studies suggest that within three to four decades, this thawing could be releasing enough greenhouse gases to make Arctic permafrost a net source of carbon dioxide rather than a sink. Through airborne and field research on missions such as CARVE and ABoVE - the latter of which will put scientists back in the field in Alaska and Canada this summer - our scientists are trying to improve measurements of this trend in order to better predict global impact.

7. Breaking Records Over Cracking Ice 

Last year was a record-breaking one for Operation IceBridge, our aerial survey of polar ice. For the first time in its nine-year history, the mission carried out seven field campaigns in the Arctic and Antarctic in a single year. In total, the IceBridge scientists and instruments flew over 214,000 miles, the equivalent of orbiting the Earth 8.6 times at the equator. 

On March 22, we completed the first IceBridge flight of its spring Arctic campaign with a survey of sea ice north of Greenland. This year marks the 10th Arctic spring campaign for IceBridge. The flights continue until April 27 extending the mission's decade-long mapping of the fastest-changing areas of the Greenland Ice Sheet and measuring sea ice thickness across the western Arctic basin.

8. OMG

Researchers were back in the field this month in Greenland with our Oceans Melting Greenland survey. The airborne and ship-based mission studies the ocean's role in melting Greenland's ice. Researchers examine temperatures, salinity and other properties of North Atlantic waters along the more than 27,000 miles (44,000 km) of jagged coastline.

9. DIY Glacier Modeling

Computer models are critical tools for understanding the future of a changing planet, including melting ice and rising seas. Our new sea level simulator lets you bury Alaska's Columbia glacier in snow, and, year by year, watch how it responds. Or you can melt the Greenland and Antarctic ice sheets and trace rising seas as they inundate the Florida coast.

10. Ice Beyond Earth

Ice is common in our solar system. From ice packed into comets that cruise the solar system to polar ice caps on Mars to Europa and Enceladus-the icy ocean moons of Jupiter and Saturn-water ice is a crucial ingredient in the search for life was we know it beyond Earth.

High-Flying Spacecraft Finish 1000th Lap Around Earth!

The quadruplet spacecraft of the Magnetospheric Multiscale mission have just returned from their first adventure into the solar wind — sailing through the most intense winds of their journey so far.

These spacecraft were designed to study Earth’s giant magnetic system, which shields our planet from the majority of the Sun’s constant outflow of material — what we call the solar wind.

Usually, the Magnetospheric Multiscale spacecraft — MMS for short — take their measurements from inside Earth’s protective magnetic environment, the magnetosphere. But in February and March, the MMS spacecraft ventured beyond this magnetic barrier to measure that solar wind directly — a feat that meant they had to change up how they fly in a whole new way.

Outside of Earth's protective magnetic field, the spacecraft were completely immersed in the particles and magnetic fields of the solar wind. As they flew through the stream of material, the spacecraft traced out a wake behind each instrument, just like a boat in a river. To avoid measuring that wake, each spacecraft was tilted into the wind so the instruments could take clean measurements of the pristine solar wind, unaffected by the wake.

Within the magnetosphere, the MMS spacecraft fly in a pyramid-shaped formation that allows them to study magnetic fields in 3D. But to study the solar wind, the mission team aligned spacecraft in a straight line at oddly spaced intervals. This string-of-pearls formation gave MMS a better look at how much the solar wind varies over different scales.

Because the four spacecraft fly so close together, MMS relies on super-accurate navigation from GPS satellites. This venture into the solar wind took the spacecraft even farther from Earth than before, so MMS broke its own world record for highest-ever GPS fix. The spacecraft were over 116,000 miles above Earth — about halfway to the Moon — and still using GPS!

Now, just in time for the 1,000th orbit of their mission — which adds up to 163 million miles flown! — the spacecraft are back in Earth's magnetosphere, flying in their usual formation to study fundamental processes within our planet’s magnetic field.

The Abyss of Time

Scotland is part of the bedrock of geology, so to speak.

In the late 18th century, Scottish farmer and scientist James Hutton helped found the science of geology. Observing how wind and water weathered rocks and deposited layers of soil at his farm in Berwickshire, Hutton made a conceptual leap into a deeper and expansive view of time. After spending decades observing the processes of erosion and sedimentation, and traveling the Scottish countryside in search of fossils, stream cuts and interesting rock formations, Hutton became convinced that Earth had to be much older than 6,000 years, the common belief in Western civilization at the time.

In 1788, a boat trip to Siccar Point, a rocky promontory in Berwickshire, helped crystallize Hutton’s view. The Operational Land Imager (OLI) on Landsat 8 acquired this image of the area on June 4, 2018, top. A closer view of Siccar Point is below.

At Siccar Point, Hutton was confronted with the juxtaposition of two starkly different types of rock—a gently sloping bed of young red sandstone that was over a near vertical slab of older graywacke that had clearly undergone intensive heating, uplift, buckling, and folding. Hutton argued to his two companions on the boat that the only way to get the two rock formations jammed up against one another at such an odd angle was that an enormous amount of time must have elapsed between when they had been deposited at the bottom of the ocean.

He was right.

How does the whole sleeping situation work with 0 gravity, or do sleep mid air?

Will we need to wear the special glasses all day or just during that 2 hour window where viewing is happening?

Deffinelty do not wear them while driving or walking around as you can’t see anything out of them (they are very very dark). But while you are driving and walking you shouldn’t be looking at the Sun anyway. You only need to wear them while you are looking at the Sun. You can use them any day to view the Sun. In a few years, when the Sun once again becomes more active, you can use these glasses and pinhole projectors to see sunspots! Make sure to check that they are ISO 12312-2 compliant, from a trusted vendor, and not scratched or damaged before using them to look at the Sun. https://eclipse2017.nasa.gov/safety

Far from Westeros, a Three-Eyed Raven Helps NASA Find Its Way

Perched on the outside of the International Space Station is Raven—a technology-filled module that helps NASA develop a relative navigation capability, which is essentially autopilot for spacecraft. Raven has been testing technologies to enable autonomous rendezvous in space, which means the ability to approach things in space without human involvement, even from the ground.

Developed by the Satellite Servicing Projects Division (SSPD), our three-eyed Raven has visible, infrared, and Lidar sensors and uses those “eyes” to image and track visiting spacecraft as they come and go from the space station. Although Raven is all-seeing, it only sees all in black and white. Color images do not offer an advantage in the case of Raven and Restore-L, which also utilize infrared and Lidar sensors.

The data from Raven’s sensors is sent to its processor, which autonomously sends commands that swivel Raven on its gimbal, or pointing system. When Raven turns using this system, it is able to track a vehicle. While these maneuvers take place, NASA operators evaluate the movements and make adjustments to perfect the relative navigation system technologies. 

A few days ago, Raven completed its 21st observation of a spacecraft when it captured images of Northrop Grumman’s Cygnus vehicle delivering science investigations and supplies as part of its 11th commercial resupply services mission, including another SSPD payload called the Robotic External Leak Locator.

And just last month, Raven celebrated its two-year anniversary in space, marking the occasion with an observation of SpaceX’s Crew Dragon during the Demo-1 mission.

What is this—a spacecraft for ants??

While this shot of Dragon isn’t terribly impressive because of where the spacecraft docked on station, Raven has captured some truly great images when given the right viewing conditions. 

From SpaceX Dragon resupply mission observations…

…to Cygnus supply vehicles.

Raven has observed six unique types of spacecraft. 

It has also conducted a few observations not involving spacecraft, including the time it captured Hurricane Irma…

…or the time it captured station’s Dextre arm removing the Robotic Refueling Mission 3 payload, another mission developed by SSPD, from the Dragon spacecraft that delivered it to the orbiting laboratory.

Thus far, Raven has had a great, productive life aboard the station, but its work isn’t done yet! Whether it’s for Restore-L, which will robotically refuel a satellite, or getting humans to the Moon or Mars, the technologies Raven is demonstrating for a relative navigation system will support future NASA missions for decades to come.
