This Week @ NASA--April 14, 2017

Cassini and the Hubble Space Telescope, two of our long-running missions, are providing new details about the ocean-bearing moons of Jupiter and Saturn. Hubble’s monitoring of plume activity on Europa and Cassini’s long-term investigation of Enceladus are laying the groundwork for our Europa Clipper mission, slated for launch in the 2020s. Also, Shane Kimbrough returns home after 171 days aboard the Space Station, celebrating the first Space Shuttle mission and more!

Ocean Worlds

Our two long-running missions, Cassini and the Hubble Space Telescope,  are providing new details about “ocean worlds,” specifically the moons of Jupiter and Saturn. 

image

The details – discussed during our April 13 science briefing – included the announcement by the Cassini mission team that a key ingredient for life has been found in the ocean on Saturn’s moon Enceladus. 

image

Meanwhile, in 2016 Hubble spotted a likely plume erupting from Jupiter’s moon Europa at the same location as one in 2014, reenforcing the notion of liquid water erupting from the moon.

image

These observations are laying the groundwork for our Europa Clipper mission, planned for launch in the 2020s.

image

Welcome Home, Shane!

Shane Kimbrough and his Russian colleagues returned home safely after spending 173 days in space during his mission to the International Space Station.

hey i’ve thought of a new way to explain the difference between math research and science research are u ready math research: Why does pizza get hot in an oven? Well, let’s first prove ovens exist. Then we can try to prove ovens get hot.  Wait, have we even proved that pizza exists? Have we proved that pizza can get hot? Have we proved that heat exists? Have we proved that I exist? That you exist? science research: Why does pizza get hot in an oven? *sticks hand into burning oven* ahhHHHHHHHHHH WHAT’S HAPPENING

Concept: fantasy world where dragons are A Thing™ but instead of them being these rare, semi-legendary creatures who exist solely to terrorise and wreak havoc and mayhem and burn inconveniences to a crisp they’re like… dogs… vaguely domesticated cats…

They come in loads of sizes and it’s a common thing to hear them scritching across your roof or rummaging in your garbage. You pass by like four every time you go to the market.

There’s even some snoozing at market stalls and strays playing with children and stealing scraps of food that fall in the street, with mottled scales and mixed textures of feathers and mismatched jewel colours.

Your favourite baker has three tiny western diamondtips who are in charge of keeping the ovens fired up and don’t always eat all of the bread. Sometimes.

Linda Bagshot on the corner has a ground rooster who can’t fly but always reaches up and stretches her neck out as far as she can to try and scrounge pets as you pass her garden wall.

A local inn is named after its summer aura who is the length of the room, all careful length and soft scales, with breath perfumed like spring breeze and scales that emanate just enough warmth to comfort, just enough that you won’t fall asleep, just enough that it’s tempting nonetheless.

The school you went to has a forest guardian older than the town itself who spends all his time slowly ambling down the corridors, and his favourites are the kids learning their first letters who like to read to him, sound out letters and marks that don’t have any correlation just yet, and you know that nobody has conclusively proven that dragons understand human tongues but you also know that if anyone understands, it’s him.

There’s a festival of dragons, a public holiday where banners are strewn and candles glow even into the wee hours and rainbow confetti and paint clogs the streets and maybe some overexcited babies set things alight but that’s ok, the town prepared better this year, far fewer people will lose their gardens and eyebrows this time, they promise.

And yes ok, there are big dragons. Ferocious dragons. Dragons that only come out once every ten years to feed and pillage. Dragons who rule the seas and shake mountains, who take flight and block out the stars. There are reasons you don’t go into the woods at night, reasons some wells are avoided, reasons entire villages up and vanished without a trace.

But there are also dragons who curl up with your children to rock them to sleep, and ward off nightmares. There are dragons who open doors and fetch supplies and guide those without sight. There are dragons who mimic words and whistles and delight in your joy when they get them just right.

There are dragons who adopt orphaned piglets, kittens, lambs, calves, puppies, ducklings. There are dragons who sunbathe and dragons who need kept on ice and dragons who climb atop weather vanes in storms to conduct electricity. Dragons who sparkle like jewels in the light and dragons who glow in the dark and dragons with flora creeping in and around their scales and dragons who sound like windchimes when they fold their wings.

Concept: there are dragons.

There are so many dragons.

2016 Sets Global Temperature Record

We just experienced the hottest year on record…again.

image

2016 was hotter than 2015, the previous record. And 2015 hotter than 2014, the previous record year.

These record temperatures are all part of a warming trend that dates back to the late-19th century, largely caused by human emissions of carbon dioxide and other gases into the atmosphere.

image

A lot of this warming trend has been in the last 35 years. In fact, 16 of the 17 warmest years on record have been since 2001.

To help us gather this data, planes and boats travel out from Antarctic research stations to gather information from the Arctic region, in addition to space-based observatories.

image

Scientists at our Goddard Institute for Space Studies analyze data from 6,300 weather stations, observations of sea surface temperature and Antarctic research stations, all to determine how the average surface temperature is changing.

image

Scientists at the National Oceanic and Atmospheric Administration separately analyze the same data to track global temperature.

The two agencies reached the same conclusion about 2016’s record-setting heat.

Variations in local weather mean parts of the globe did not experience a record-setting year. Some places still had snow, cold weather and below-record temperatures, but the overall global average was higher than any previous year.

image

For instance, according to NOAA the average temperature in the 48 contiguous United States was not quite as high as in 2015, which still holds the record.

image

A combination of space- and land-based measurements gives us a unique perspective on Earth, the only planet we know of that supports life.

on the topic of humans being the intergalactic “hold my beer” species: imagine an alien stepping onto a human starship and seeing a space roomba™ with a knife duct taped onto it, just wandering around the ship

it doesn’t have any special intelligence. it’s just a normal space roomba. there are other space roombas on the ship and they don’t have knives. it’s just this one. knife space roomba has full clearance to every room in the ship. occasionally crew members will be talking and then suddenly swear and clutch their ankle. knife space roomba putters off, leaving them to their mild stab wounds.

“what is the point?” asks the alien as another crew member casually steps over the knife-wielding robot. “is it to test your speed and agility?”

“no it doesn’t really go that fast,” replies the captain.

“does it teach you to stay ever-vigilant?”

“I mean I guess so but that’s more of a side effect.”

“does it weed out the weak? does it protect you from invaders? do repeated stabbings let your species heal more quickly in the future?”

“it doesn’t stab very hard, it gets us more than it gets our enemies, and no, but that sounds cool — someone write that down.”

“but then what is its purpose?”

“I don’t know,” the captain says, leaning down to give the space roomba an affectionate pat. “it just seemed cool”

2016: This Year at NASA!

As 2016 comes to a close and prospects of the new year loom before us, we take a moment to look back at what we’ve accomplished and how it will set us ahead in the year to come.

2016: This Year At NASA!

2016 marked record-breaking progress in our exploration activities. We advanced the capabilities needed to travel farther into the solar system while increasing observations of our home and the universe, learning more about how to continuously live and work in space and, or course, inspiring the next generation of leaders to take up our journey to Mars and make their own discoveries.

Here are a few of the top NASA stories of 2016…

International Space Station

One Year Mission…completed!

image

NASA astronaut Scott Kelly and Russian cosmonaut Mikhail Kornienko returned to Earth after spending a year in space. Testing the limits of human research, findings from their One Year Mission will help send humans farther into space than ever before.

Commercial Resupply

image

Commercial partners Orbital ATK and SpaceX delivered tons (yes literally tons) of cargo to the International Space Station. This cargo supported hundreds of science experiments and technology demonstrations crucial to our journey to Mars.

Mars

Expandable Habitats

image

The Bigelow Expandable Activity Module (BEAM) was one of the technology demonstrations delivered to the space station in April. Expandable habitats greatly decrease the amount of transport volume for future space missions.

Booster Test Firing

image

In June, a booster for our Space Launch System (SLS) rocket successfully fired up. It will be used on the first un-crewed test flight of SLS with the Orion spacecraft in 2018. Eventually, this rocket and capsule will carry humans into deep space and one day…Mars!

InSight

image

This year we updated the milestones for our InSight mission with a new target launch window beginning in May 2018. This mission will place a fixed science outpost on Mars to study its deep interior. Findings and research from this project will address one of the most fundamental questions we have about the planetary and solar system science…how in the world did these rocky planets form?

Solar System and Beyond

Juno

image

On July 4, our Juno spacecraft arrived at Jupiter. This mission is working to improve our understanding of the solar system’s beginnings by revealing the origin and evolution of Jupiter.

OSIRIS-REx

image

In September, we launched our OSIRIS-REx spacecraft…which is America’s first-ever asteroid sample return mission. This spacecraft will travel to a near-Earth asteroid, called Bennu, where it will collect a sample to bring back to Earth for study.

James Webb Space Telescope

image

In February, the final primary mirror segment of our James Webb Space Telescope was installed. This will be the world’s most powerful space telescope ever, and is scheduled to launch in 2018. Webb will look back in time, studying the very first galaxies ever formed.

Kepler

image

In May, our Kepler mission verified the discovery of 1,284 new planets. Kepler is the first NASA mission to find potentially habitably Earth-sized planets.

Earth Right Now

Earth Expeditions

image

Our efforts to improve life on Earth included an announcement in March of a collection of Earth Science field campaigns to study how our planet is changing. These Earth Expeditions sent scientists to places like the edge of the Greenland ice sheet to the coral reefs of the South Pacific to delve into challenging questions about how our planet is changing…and what impacts humans are having on it.

Small Satellites

image

In November, we announced plans to launch six next-generation Earth-observing small satellite missions. One uses GPS signals to measure wind in hurricanes and tropical systems in greater detail than ever before.

Aeronautics Research

Our efforts in 2016 to make air travel cleaner, safer and quieter included new technology to improve safety and efficiency of aircraft arrivals, departures and service operations.

X-Plane

2016: This Year At NASA!

In June, we highlighted our first designation of an experimental airplane, or X-plane, in a decade. It will test new electric propulsion technology.

Drone Technolgy

2016: This Year At NASA!

In October, we evaluated a system being developed for the Federal Aviation Administration to safely manage drone air traffic.

Technology

Electric Propulsion

2016: This Year At NASA!

We selected Aerojet Rocketdyne to develop and advanced electric propulsion system to enable deep space travel to an asteroid and Mars.

Spinoffs

2016: This Year At NASA!

Our technology transfer program continued to share the agency’s technology with industry, academia and other government agencies at an unprecedented rate.

Centennial Challenges

2016: This Year At NASA!

Our Centennial Challenges program conducted four competition events in 2016 to spark innovation and enable solutions in important technology focus areas.

Ad Astra, John Glenn (1921-2016)

An astronaut. 

A pilot. 

A husband. 

A father. 

A United States Senator.

An American hero. 

An original.

image

John Glenn (1921-2016) was all those things and more. When he rocketed into space on Feb. 20, 1962, to become the first American to orbit Earth, the flight set the nation on course to meet ever-more ambitious goals.

The life and career of Senator Glenn eclipses those of many. In spite of his accomplishments, he was a humble and gracious man (and 4-term U.S. senator).

During Glenn’s first flight, a scheduled 30-minute test to determine whether Glenn could fly the capsule manually became a matter of life and death when the automatic system malfunctioned after the first orbit.

image

“I went to manual control and continued in that mode during the second and third orbits, and during re-entry,” Glenn recalled later.  “The malfunction just forced me to prove very rapidly what had been planned over a longer period of time.” Another problem seemed even more serious – telemetry indicated the spacecraft’s heat shield was loose. It seemed possible that Glenn and the spacecraft would be incinerated on re-entry.  Glenn left the retrorocket pack in place to steady the heat shield during re-entry. “It made for a very spectacular re-entry from where I was sitting,” he said. Big chunks of the burning material came flying by the window.

image

He wasn’t sure whether the flaming debris was the rocket pack or the heat shield breaking up. “Fortunately,” he told an interviewer,“ it was the rocket pack – or I wouldn’t be answering these questions.”

image

In the words of President Obama, who awarded him the Presidential Medal of Freedom in 2012: “When John Glenn blasted off from Cape Canaveral atop an Atlas rocket in 1962, he lifted the hopes of a nation. And when his Friendship 7 spacecraft splashed down a few hours later, the first American to orbit the Earth reminded us that with courage and a spirit of discovery there’s no limit to the heights we can reach together. With John’s passing, our nation has lost an icon and Michelle and I have lost a friend. John spent his life breaking barriers, from defending our freedom as a decorated Marine Corps fighter pilot in World War II and Korea, to setting a transcontinental speed record … The last of America’s first astronauts has left us, but propelled by their example we know that our future here on Earth compels us to keep reaching for the heavens.  On behalf of a grateful nation, Godspeed, John Glenn.”

image

Glenn left the Astronaut Corps in 1964 and resigned from the Marine Corps in 1965. And, after some time in private industry ran for and was elected ti the U.S. Senate in 1974, carrying all 88 counties of Ohio. He was re-elected in 1980 with the largest margin in Ohio history. Ohio returned him to the Senate for a third term in 1986. In 1992 he was elected again, becoming the first popularly elected senator from his state to win four consecutive terms. During his last term he was the ranking member of both the Governmental Affairs Committee and the Subcommittee on Air/Land Forces in the Senate Armed Services Committee. He also served on the Select Committee on Intelligence and the Special Committee on Aging. He was considered one of the Senate’s leading experts on technical and scientific matters, and won wide respect for his work to prevent the spread of weapons of mass destruction.

image

In 1998, Glenn flew on the STS-95 Discovery shuttle flight, a 9-day mission during which the crew supported a variety of research payloads including deployment of the Spartan solar-observing spacecraft, the Hubble Space Telescope Orbital Systems Test Platform, and Glenn’s investigations on space flight and the aging process.

NASA Administrator Charlie Bolden remembers, “Senator Glenn’s legacy is one of risk and accomplishment, of history created and duty to country carried out under great pressure with the whole world watching.”

Today, we honor him for all that he stood for and continues to stand for – grace under pressure, humility, ability, strength. 

Godspeed, John Glenn.

Black (Hole) Friday!

It’s Black Friday, but for us, it’s the annual Black Hole Friday! Today, we’ll post awesome images and information about black holes.

Black (Hole) Friday!

A black hole is a place in space where gravity pulls so much that even light cannot get out. The gravity is so strong because matter has been squeezed into a tiny space…sort of like all of those shoppers trying to fit into the department stores today.

Because no light can get out, you can’t see black holes with the naked eye. Space telescopes with special tools  help find black holes (sort of how those websites help you find shopping deals).

Black (Hole) Friday!

How big are black holes? Black holes can be large or small…just like the lines in all of the stores today. Scientists think the smallest black holes are as small as just one atom. These black holes are very tiny but have the mass of a large mountain! 

Black (Hole) Friday!

So how do black holes form? Scientists think the smallest black holes formed when the universe began. Stellar black holes are made when the center of a very big star collapses. When this happens, it causes a supernova. 

Black (Hole) Friday!

A supernova is an exploding star that blasts part of its mass into space. 

Black (Hole) Friday!

Supermassive black holes are an altogether different story. Scientists think they were made at the same time as the galaxy they in they reside. Supermassive black holes, with their immense gravitational pull, are notoriously good at clearing out their immediate surroundings by eating nearby objects. When a star passes within a certain distance of a black hole, the stellar material gets stretched and compressed – or “spaghettified” – as the black hole swallows it. A black hole destroying a star, an event astronomers call “stellar tidal disruption,” releases an enormous amount of energy, brightening the surroundings in an event called a flare. In recent years, a few dozen such flares have been discovered.

Black (Hole) Friday!

Then there are ultramassive black holes, which are found in galaxies at the centers of massive galaxy clusters containing huge amounts of hot gas.

Get more fun facts and information about black holes.

10 Technologies That Are Changing the Game

Earlier this year, we hosted a Game Changing Technology Industry Day for the aerospace industry, and in October our engineers and technologists visited Capitol Hill showcasing some of these exciting innovations. Check out these technology developments that could soon be making waves on Earth and in space.

1. Wearable technology

image

With smartwatches, glasses, and headsets already captivating users around the world, it’s no surprise that the next evolution of wearable technology could be used by first responders at the scene of an accident or by soldiers on a battlefield. The Integrated Display and Environmental Awareness System (IDEAS) is an interactive optical computer that works for smart glasses. 

image

It has a transparent display, so users have an unobstructed view even during video conferences or while visualizing environmental data. 

image

And while the IDEAS prototype is an innovative solution to the challenges of in-space missions, it won’t just benefit astronauts – this technology can be applied to countless fields here on Earth.

2. Every breath they take: life support technologies

Before astronauts can venture to Mars and beyond, we need to significantly upgrade our life support systems. The Next Generation Life Support project is developing technologies to allow astronauts to safely carry out longer duration missions beyond low-Earth orbit. 

image

The Variable Oxygen Regulator will improve the control of space suit pressure, with features for preventing decompression sickness. The Rapid Cycle Amine technology will remove carbon dioxide and humidity and greatly improve upon today’s current complex system.

image

3. 3-D printing (for more than just pizza)

New Advanced Manufacturing Technologies (AMT), such as 3-D printing, can help us build rocket parts more quickly and aid in building habitats on other planets. 

image

These manufacturing initiatives will result in innovative, cost-efficient solutions to many of our planetary missions. Back in 2014, the International Space Station’s 3-D printer manufactured the first 3-D printed object in space, paving the way to future long-term space expeditions. 

image

The object, a printhead faceplate, is engraved with names of the organizations that collaborated on this space station technology demonstration: NASA and Made In Space, Inc., the space manufacturing company that worked with us to design, build and test the 3-D printer.

image

4. Spacecraft landing gear

Large spacecraft entering the atmosphere of Mars will be traveling over five times the speed of sound, exposing the craft to extreme heat and drag forces. The Hypersonic Inflatable Aerodynamic Decelerator (HIAD) is designed to protect spacecraft from this environment with an inflatable structure that helps slow a craft for landing. 

image

To get astronauts and other heavy loads to the surface safely, these components must be very strong. The inflatable consists of a material 15 times stronger than steel, while the thermal protection system can withstand temperatures over 1600°C.

5. From heat shield technology to firefighter shelters

image

For the Convective Heating Improvement for Emergency Fire Shelters (CHIEFS) project, we partnered with the U.S. Forest Service to develop safer, more effective emergency fire shelters for wild land firefighters. 

image

Using existing technology for flexible spacecraft heat shields like HIAD, we are building and testing new fire shelters composed of stacks of durable, insulated materials that could help protect the lives of firefighters.

image

6. Robots and rovers

Real life is looking a bit more like science fiction as Human Robotics Systems are becoming highly complex. They are amplifying human productivity and reducing mission risk by improving the effectiveness of human-robot teams. 

image

Our humanoid assistant Robonaut is currently aboard the International Space Station helping astronauts perform tasks.

image

A fleet of robotic spacecraft and rovers already on and around Mars is dramatically increasing our knowledge and paving the way for future human explorers. The Mars Science Laboratory Curiosity rover measured radiation on the way to Mars and is sending back data from the surface. 

image

This data will help us plan how to protect the astronauts who will explore Mars. 

image

Future missions like the Mars 2020 rover, seeking signs of past life, will demonstrate new technologies that could help astronauts survive on the Red Planet.

image

7. Robotic repairs

Currently, a satellite that is even partially damaged cannot be fixed in orbit. Instead, it must be disposed of, which is a lot of potential science lost.

image

Satellite Servicing technologies would make it possible to repair, upgrade, and even assemble spacecraft in orbit using robotics.

image

This can extend the lifespan of a mission, and also enable deeper space exploration. 

image

Restore-L, set to launch in 2020, is a mission that will demonstrate the ability to grab and refuel a satellite.

8. Low-cost spacecraft avionics controllers

Small satellites, or smallsats, are quickly becoming useful tools for both scientists and industry. However, the high cost of spacecraft avionics—the systems that guide and control the craft—often limits how and when smallsats can be sent into orbit by tagging along as payloads on larger launches. 

image

Using Affordable Vehicle Avionics (AVA) technology, we could launch many more small satellites using an inexpensive avionics controller. This device is smaller than a stack of six CD cases and weighs less than two pounds!

9. Making glass from metal

After a JPL research team of modern-day alchemists set about mixing their own alloys, they discovered that a glass made of metal had the wear resistance of a ceramic, was twice as strong as titanium, and could withstand the extreme cold of planetary surfaces, with temperatures below -150 degrees Fahrenheit.

image

Bulk Metallic Glass (BMG) gears would enable mechanisms to function without wasting energy on heaters. Most machines need to maintain a warmer temperature to run smoothly, which expends precious fuel and decreases the mission’s science return. 

image

By developing gearboxes made of BMG alloys, we can extend the life of a spacecraft and learn more about the far reaches of our solar system than ever before. Plus, given their extremely high melting points, metallic glasses can be cheaply manufactured into parts by injection molding, just like plastics.

10. Lighter, cheaper, safer spacecraft fuel tanks

Cryogenic propellant tanks are essential for holding fuel for launch vehicles like our Space Launch System—the world’s most powerful rocket. But the current method for building these tanks is costly and time-consuming, involving almost a mile of welded parts.

image

Advanced Near Net Shape Technology, part of our Advanced Manufacturing Technologies, is an innovative manufacturing process for constructing cryotanks, using cylinders that only have welds in one area. 

image

This makes the tank lighter, cheaper, and safer for astronauts, as there are fewer potentially defective welds.

Because of Webb’s visually striking appearance, the project hosted a special viewing event on Wednesday, Nov. 2, 2016.

image

Photo Credit: Maggie Masetti

There was an overwhelming response to the event invitation and ultimately twenty-four people were selected to attend. They represented a broad range of artistic media and styles, including: watercolor, 3D printed sculpture, silk screening, acrylics, sumi-e (East Asian brush technique), comics, letterpress, woodwork, metalwork, jewelry making, fiber art, ink, mural painting, kite-making, tattooing, scientific illustration, poetry, songwriting, and video making.

image

Project scientists and engineers spoke with visitors to give context to what they were seeing and explain why Webb is an engineering marvel, and how it will change our view of the universe. 

image

Among other things, Webb will see the first stars and galaxies that formed in the early universe and help us to better understand how planetary systems form and evolve. It will help us answer questions about who we, as humans, are and where we came from.

image

Finished art from the event continues to be added HERE.

The James Webb Space Telescope is finishing environmental testing at our Goddard Space Flight Center in Greenbelt, Maryland. Next it will head to our Johnson Space Center in Houston for an end-to-end test at cryogenic temperatures. After that, it goes to Northrop Grumman to be mated with the giant tennis court-sized sunshield and the spacecraft bus.  The observatory will launch in October of 2018 from a European Space Agency (ESA) launch site in French Guiana, aboard an Ariane 5 rocket.  Webb is a collaboration of NASA, ESA, and the Canadian Space Agency (CSA).

10 “Out of This World" Facts About the James Webb Space Telescope

Wouldn’t it be neat to see a period of the universe’s history that we’ve never seen before? That’s exactly what the James Webb Space Telescope (JWST) will be able to do…plus more!

Specifically, Webb will see the first objects that formed as the universe cooled down after the Big Bang. We don’t know exactly when the universe made the first stars and galaxies – or how for that matter. That is what we are building Webb to help answer.

Here are 10 awesome facts about this next generation space telescope:

1. The James Webb Space Telescope is the world’s largest and next premier space observatory. It will extend the discoveries of the Hubble Space telescope and observe the birthplaces of stars, galaxies, planets and life over billions of years.

2. It is named after James Webb, NASA’s second administrator and champion of our science.

3. At 3 stories high and the size of a tennis court, it will be 100 times more powerful than Hubble!

4. It is so big that it has to fold origami-style to fit in the rocket, which is only 5.4 meters wide…And then it will unfurl, segment by segment, once in space.

5. The telescope will observe infrared light with unprecedented sensitivity. It will see the first galaxies born after the Big Bang over 13.5 billion years ago.

6. Webb’s infrared cameras are so sensitive they must be shielded from light from the sun, Earth, and moon. The 5-layer sunshield is like having sunblock of SPF 1 million.

7. Webb will orbit the sun 1 million miles from Earth, where the telescope will operate at temperatures below -390 F (-235 C).

8. Webb’s mirrors are coated with a super thin layer of gold only about 1000 atoms thick to optimize their reflectivity in the infrared.

9. Webb will launch from French Guiana in 2018. It is launched near the equator because the faster spin of Earth there gives the rocket an extra push.

10. Webb is an international mission, with contributions from the European Space Agency and Canadian Space Agency. Once operational, scientists from all over the world will be able to use Webb to explore our solar system, planets outside our solar system, stars and galaxies.
