Eight Small Satellites Will Give Us A New Look Inside Hurricanes

2019 Temperature By the Numbers

The Year

2nd Hottest

2019 was the second-hottest year since modern record keeping began. NASA and the National Oceanic and Atmospheric Administration work together to track temperatures around the world and study how they change from year to year. For decades, the overall global temperature has been increasing.

Over the long term, world temperatures are warming, but each individual year is affected by things like El Niño ocean patterns and specific weather events.

The global temperature is an average, so not every place on Earth had its second-warmest year. For instance, the continental U.S. had a cold October, but Alaska set records for high temperatures. The U.S. was still warmer than average over the year.

Globally, Earth’s temperature in 2019 was more than 2°F warmer than the late 19th Century.

The Record

140 years 

Since 1880, we can put together a consistent record of temperatures around the planet and see that it was much colder in the late-19th century. Before 1880, uncertainties in tracking global temperatures are larger. Temperatures have increased even faster since the 1970s, the result of increasing greenhouse gases in the atmosphere.

10 years

The last decade was the hottest decade on record.

20,000 Individual Observations

Scientists from NASA use data from more than 20,000 weather stations and Antarctic research stations, together with ship- and buoy-based observations of sea surface temperatures to track global temperatures.

The Consequences

90%

As Earth warms, polar ice is melting at an accelerated rate. The Arctic is warming even faster than the rest of the planet. This northern summer, 90% of the surface of the Greenland Ice Sheet melted.

8 inches

Melting ice raises sea levels around the world. While ice melts into the ocean, heat also causes the water to expand. Since 1880, sea levels globally have risen approximately 8 inches, although regional rates of sea level rise can be even higher.

100+ fires

As temperatures increase, fire seasons burn hotter and longer. During June and July 2019, more than 100 long-lived and intense wildfires burned north of the Arctic circle. This year also saw intense, record-setting fires in Australia.

46% increase in CO2 levels

This decades-long warming trend is the result of increasing greenhouse gases in the atmosphere, released by human activities.

Hey! I was wondering how everyone on the ISS adjusts to each other’s culture and language. It seems like it might be hard with language barriers and other factors, to live in a confined space with people from another country. Do others try to teach you their language? Does everyone mostly speak English, or do some people speak Russian?

Did you have an innate talent for math? Or did you struggle and practiced until you understood it? I wanted to become an aerospace engineer but after taking a class I decided psychology was more suited for me because I struggled with equations but thrived with the psychological terms

Anything you don’t know is hard until you learn it. There are a few geniuses in the world, but most people study and work hard to learn what they love. Even the smartest amongst you actually put in a lot of time to learn the things that they want, and no one is an exception. You have to put in the time.

8 Things to Know About Our Commercial Crew Program

Two years after selecting the next generation of American spacecraft and rockets that will launch astronauts to the International Space Station, engineers and spaceflight specialists across our Commercial Crew Program, Boeing and SpaceX are putting in place the elements required for successful missions.

1. The Goal

The goal of our Commercial Crew Program is to return human spaceflight launches to U.S. soil, providing reliable and cost-effective access to low-Earth orbit on systems that meet our safety requirements. To accomplish this goal, we are taking a unique approach by asking private companies, Boeing and SpaceX, to develop human spaceflight systems to take over the task of flying astronauts to station.

2. Multi-User Spaceport

Boeing and SpaceX, like other commercial aerospace companies, are capitalizing on the unique experience and infrastructure along the Space Coast at our Kennedy Space Center and Cape Canaveral Air Force Station. Kennedy has transitioned from a government-only launch complex to a premier multi-user spaceport. In the coming years, the number of launch providers along the Space Coast is expected to more than double.

3. Innovation

Our expertise has been joined with industry innovations to produce the most advanced spacecraft to ever carry humans into orbit. Each company is developing its own unique systems to meet our safety requirements, and once certified by us, the providers will begin taking astronauts to the space station.

4. Research

With two new spacecraft that can carry up to four astronauts to the International Space Station with each of our missions, the number of resident crew will increase and will double the amount of time dedicated to research. That means new technologies and advances to improve life here on Earth and a better understanding of what it will take for long duration, deep space missions, including to Mars.  

5. Crew Training

Astronauts Bob Behnken, Eric Boe, Doug Hurley and Suni Williams have been selected to train to fly flight tests aboard the Boeing CST-100 Starliner and SpaceX Crew Dragon.

The veteran crew have sent time in both spacecraft evaluating and training on their systems. Both providers are responsible for developing every aspect of the mission, from the spacesuits and training, to the rocket and spacecraft.

6. Launch Abort System

Boeing and SpaceX will equip their spacecraft with launch abort systems to get astronauts out of danger . . . FAST!

7. Expedited Delivery

Time-sensitive, critical experiments performed in orbit will be returned to Earth aboard commercial crew spacecraft, and returned to the scientists on Earth in hours, instead of days – before vital results are lost. That means better life and physical science research results, like VEGGIE, heart cells, and protein crystals.

8. Lifeboat 

The spacecraft will offer safe and versatile lifeboats for the crew of the space station, whether an emergency on-orbit causes the crew to shelter for a brief time in safety, or leave the orbiting laboratory altogether. Learn more HERE.

What is a typical day in the international space station like?? I cant help but express my admiration for you.

Five Ways NASA’s Internships Rock(et)

Sending humans to space, returning to the Moon, transforming aircraft, exploring the extraordinary every day: just a few things you are a part of as a NASA intern. Whether you have dreamed of working at the agency your whole life, or discovered a new interest, students at NASA have the opportunity to make real contributions to space exploration and flight. Want to know more? Here are five ways these internships can be rocket fuel for your career:

5. NASA gives you a navigation system. 

Imagine walking into a lab to work side-by-side with NASA scientists, engineers and researchers. As a NASA intern, that’s a daily reality. Mentors are full-time employees who guide and work with students throughout their internship. Space communications intern Nick Sia believes working with a mentor is what makes NASA’s internships different. “Working one-on-one has given me more opportunities to work on different projects,” he says. “It’s the best motivation to do great work.”

4. It’s more than training for launch day. 

As a NASA intern, your work matters. Students are treated as employees, and their ideas are valued. Hands-on assignments allow interns to make real contributions to NASA research and gain experience. For example, Erin Rezich is working in our mobility lab to help design excavation hardware for planetary surfaces such as the Moon. “It’s an incredibly exciting project because these are problems that have to be solved to move planetary exploration forward,” she says.

3. Students develop an array of skills.

Not only do interns improve their technical skills, but they are also building communication and leadership skills. This summer, students are taking part in a two-week immersive design challenge. Participants will design a Ram Air Turbine for NASA Glenn’s 1x1 Supersonic Wind Tunnel. “This design challenge is a unique opportunity to create a design from scratch, which could actually be implemented,” says Woodrow Funk, an electrical testing engineer intern. Projects such as this allow students to work independently, plan, organize and improve time management skills. 

2. Non-technical degrees shoot for the stars. 

NASA also offers many opportunities for students pursuing a career outside of STEM fields. Departments such as human resources, administration, education and communications engage students with hands-on projects. These organizations provide support essential to NASA’s programs and missions. “I was excited that NASA offered opportunities that match my skill set,” says Molly Kearns, a digital media student working with Space Communications and Navigation. Kearns’ first summer at NASA confirmed her passion for graphic design. “What makes the experience so rewarding is seeing content that I created published on social media sites,” she says.

1. Students are surrounded by extraordinary peers. 

Students come to NASA from all over the nation to develop important skills matched to their career goals and expand the way they think about their work. Being surrounded by the best scientists, developers, engineers, mathematicians and communicators is inspiring. NASA’s network is one of graduate fellow Jamesa Stokes’ main motivations. “There are tons of smart and awesome people who work here,” says Stokes, “At the end of the day, they are willing to help anyone who comes and asks for it.”

Today we celebrate the mission that piqued our curiosities, and drove NASA’s perseverance to pursue further exploration of the Red Planet. The Sojourner rover landed on July 4, 1997, after hitching a ride aboard the Mars Pathfinder mission. Its innovative design became the template for future missions. The rover, named after civil rights pioneer Sojourner Truth, outlived its design life 12 times. This panoramic view of Pathfinder's Ares Vallis landing site shows Sojourner rover is the distance.

Astronaut Candidates Report for Duty

Fourteen new Astronaut Candidates have reported to our Johnson Space Center in Houston for duty on Monday, Aug. 21! Two astronauts from the Canadian Space Agency (CSA), along with our 12 new astronaut candidates arrived for their first day of work. We selected these 12 individuals from a record number of more than 18,000 applicants. 

This excited group of outstanding individuals will begin 2 years of training, along with 2 Canadian astronauts, in 5 key areas before being assigned to a mission.

What 5 areas? Let’s take a look...

1. Operate in T-38 Jets

Astronauts must be able to safely operate in the T-38 jets as either a pilot or back seater. 

2. Operate + Maintain the International Space Station

Astronauts learn to operate and maintain the complex systems aboard the International Space Station. Did you know they recycle their water there? Today’s coffee is...well, tomorrow’s coffee too. 

3. Learn How to Spacewalk

Or should we say waterwalk? Astronauts demonstrate the skills to complete complex spacewalk tasks in our Neutral Buoyancy Laboratory. This 6.2 million gallon pool contains a mockup of the space station and is a close simulation to microgravity.

4. Learn to Operate a Robot

Astronauts train in Canada for 2 weeks to learn how to capture visiting vehicles and more with the space station’s Canadarm 2 robotic arm. 

5. Learn a Foreign Language

Astronauts must be fluent in both English and Russian, the two official languages on the International Space Station. 

But before they begin all this training...they had to report for duty...

This group reported for Johnson Space Center on eclipse day and was sworn in as NASA’s Astronaut Candidate Class of 2017.

They even got to experience the partial solar eclipse together, what a great first day!

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.
