Astronaut Journal Entry - The Last Week

How Climate Change Showed Up in 2021

2021 was tied for the sixth-hottest year since modern record keeping began. We work together with the National Oceanic and Atmospheric Administration to track temperatures around the world and study how they change from year to year.

For decades, the overall global temperature has been increasing because of human activities. The last decade has been the warmest on record. Each individual year’s average temperature, however, can be affected by things like ocean circulation, volcanic eruptions, and specific weather events.

For instance, last year we saw the beginning of La Niña – a pattern of cooler waters in the Pacific – that was responsible for slightly cooling 2021’s average temperature. Still, last year continued a long-term trend of global warming.

Globally, Earth’s temperature in 2021 was nearly 2°F warmer than the late 19th Century, for the seventh year in a row.

The Record

Studying 142 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.

Tracking Millions of Individual Observations

Our scientists use millions of individual observations of 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.

Reviewing Multiple Independent Records

Our global temperature record – GISTEMP – is one of a number of independent global temperature records, all of which show the same pattern of warming.

The Consequences

Everywhere Experiences Climate Change Differently

As Earth warms, temperature changes occur unevenly around the globe. The Arctic is currently warming about four times faster than the rest of the planet – a process called Arctic amplification. Similarly, urban areas tend to warm faster than rural areas, partly because building materials like asphalt, steel and concrete retain heat.

Droughts and Floods in Warmer Weather

More than 88% of the Western US experienced drought conditions in 2021. At the same time, communities in Western Europe saw two months’ worth of rain in 24 hours, breaking records and triggering flash floods. Because a hotter climate means more water can be carried in the atmosphere, areas like the Western US suffer drought from the increased 'thirstiness' of the atmosphere, while precipitation events can become more extreme as the amount of moisture in the atmosphere rises.

Sea Levels Continue to Rise

Melting ice raises sea levels around the world, as meltwater drains into the ocean. In addition, heat causes the ocean water to expand. From 1993 to today, global mean sea level has been rising around 3.4 millimeters per year. In 2021, sea level data from the recently launched NASA/ESA Sentinel-6 Michael Freilich mission became available to the public.

There is Hope

“This is not good news, but the fact that we are able to track this in real time and understand why it’s changing, and get people to notice why it’s changing and how we can change things to change the next trajectory, that gives me hope. Because we’re not in the dark here. We’re not the dinosaurs who are unaware the comet is coming. We can see the comet coming, and we can act.” – Dr. Gavin Schmidt, director of NASA GISS, where the global temperature record is calculated

From Racing Suits to Robotic Gloves: How to Gear Up with NASA Technology

Did you know you are surrounded by NASA technology? From your apartment building to the doctor’s office, and even in your cellphone camera, there is more space in your life than you think!

In the latest edition of Spinoff, we are introducing dozens of new ways NASA technology could cross your path. Whether you need an extra “hand” on the production line or a weatherproof jacket, check out how to gear up with technology made for space.

Grip-Strengthening Glove

Robots are crucial to exploring space and other planets – they could even support astronauts and form the advance party for places humans have yet to reach. But the human machine is hard to replicate.

A collaboration with General Motors helped us build Robonaut 2 – and the design for this robot’s hands has been adapted into a robotic glove that helps manufacturing employees, such as automobile workers, reduce injuries and improve quality control.

The Swedish company Bioservo used the Robo-Glove technology to create the world’s first industrial-strength robotic glove for factory workers who perform repetitive manual tasks.

The Ironhand glove adds force to the user’s grip with artificial tendons and pressure sensors on the palm and the fingers.

The result? Reduced strain on the user’s own tendons and muscles, meaning fewer workplace stress injuries and better comfort for workers.

Temperature-Control Fabrics

Spacesuits need major insulation and temperature control to protect astronauts on extravehicular activities, aka spacewalks. To help solve this, we created a phase-change material with help from the Triangle Research and Development Corporation.

With funding from a NASA Small Business Innovation Research contract, Triangle incorporated the material into a fabric glove insert that could maintain a steady temperature by absorbing and releasing heat, ensuring it feels just right.

While the invention never made it to orbit, it did make it into the driver’s seat.

Outlast Technologies exclusively licensed the material from Triangle and has incorporated it into outdoor gear, bedding, and now – auto racing suits with help from Cambridge, England-based Walero.

Due to extreme temperatures in the cockpit, drivers in almost every major racing championship wear Walero for its cooling properties. Cristiana Oprea (pictured) wears it while driving for the European Rally Championship. Credit: Walero

The race undergarments, bonded with fire-retardant material for added protection, help drivers maintain a lower core temperature and heart rate, which means fewer mistakes and better lap times.

The suits have been sold to both amateur racers and professional NASCAR drivers.

Lightweight Rain Jackets

The superinsulating material that makes up space blankets is one of our most ubiquitous spinoffs. Found everywhere from inside the walls and roofs of buildings to cryogenic tanks and MRI machines, radiant barrier technology was first created to insulate spacesuits and spacecraft. And now this NASA spinoff can be found in weatherproof jackets as well.

Inspired by her passion to run following a series of surgeries to help correct a life-threatening injury, Hema Nambiar launched her Larchmont, New York, start-up company 13-One. To create her jacket, she worked with Advanced Flexible Materials Inc.’s brand Heatsheets. The brand was already marketing products like the space blankets traditionally distributed after races to prevent dangerous drops in temperature.

The 13-One jackets are designed to be warm and weatherproof, but their thin, reflective lining lets them also be lightweight and easily portable. Credit: Lourenso Ramautar, Out of New York Studio

The resulting line of jackets has a black exterior and a lining to reflect body heat. They weigh less than a pound, are wind- and water-resistant, and easily pack into a small, built-in pouch.

How will the James Webb Space Telescope change how we see the universe? Ask an expert!

The James Webb Space Telescope is launching on December 22, 2021. Webb’s revolutionary technology will explore every phase of cosmic history—from within our solar system to the most distant observable galaxies in the early universe, to everything in between. Postdoctoral Research Associate Naomi Rowe-Gurney will be taking your questions about Webb and Webb science in an Answer Time session on Tuesday, December 14 from noon to 1 p.m EST here on our Tumblr!

🚨 Ask your questions now by visiting http://nasa.tumblr.com/ask.

Dr. Naomi Rowe-Gurney recently completed her PhD at the University of Leicester and is now working at NASA Goddard Space Flight Center as a postdoc through Howard University. As a planetary scientist for the James Webb Space Telescope, she’s an expert on the atmospheres of the ice giants in our solar system — Uranus and Neptune — and how the Webb telescope will be able to learn more about them.

The James Webb Space Telescope – fun facts:

Webb is so big it has to fold origami-style to fit into its rocket and will unfold like a “Transformer” in space.

Webb is about 100 times more powerful than the Hubble Space Telescope and designed to see the infrared, a region Hubble can only peek at.

With unprecedented sensitivity, it will peer back in time over 13.5 billion years to see the first galaxies born after the Big Bang––a part of space we’ve never seen.

It will study galaxies near and far, young and old, to understand how they evolve.

Webb will explore distant worlds and study the atmospheres of planets orbiting other stars, known as exoplanets, searching for chemical fingerprints of possible habitability.

10 Things: Why Cassini Mattered

One year ago, on Sept. 15, 2017, NASA’s Cassini spacecraft ended its epic exploration of Saturn with a planned dive into the planet’s atmosphere--sending back new science to the last second. The spacecraft is gone, but the science continues. Here are 10 reasons why Cassini mattered...

1. Game Changers

Cassini and ESA (European Space Agency)’s Huygens probe expanded our understanding of the kinds of worlds where life might exist.

2. A (Little) Like Home

At Saturn’s largest moon, Titan, Cassini and Huygens showed us one of the most Earth-like worlds we’ve ever encountered, with weather, climate and geology that provide new ways to understand our home planet.

3. A Time Machine (In a Sense)

Cassini gave us a portal to see the physical processes that likely shaped the development of our solar system, as well as planetary systems around other stars.

4. The Long Run

The length of Cassini’s mission enabled us to observe weather and seasonal changes over nearly half of a Saturn year, improving our understanding of similar processes at Earth, and potentially those at planets around other stars.

5. Big Science in Small Places

Cassini revealed Saturn’s moons to be unique worlds with their own stories to tell.

6. Ringscape

Cassini showed us the complexity of Saturn’s rings and the dramatic processes operating within them.

7. Pure Exploration

Some of Cassini’s best discoveries were serendipitous. What Cassini found at Saturn prompted scientists to rethink their understanding of the solar system.

8. The Right Tools for the Job

Cassini represented a staggering achievement of human and technical complexity, finding innovative ways to use the spacecraft and its instruments, and paving the way for future missions to explore our solar system.

9. Jewel of the Solar System

Cassini revealed the beauty of Saturn, its rings and moons, inspiring our sense of wonder and enriching our sense of place in the cosmos.

10. Much Still to Teach Us

The data returned by Cassini during its 13 years at Saturn will continue to be studied for decades, and many new discoveries are undoubtedly waiting to be revealed. To keep pace with what’s to come, we’ve created a new home for the mission--and its spectacular images--at https://solarsystem.nasa.gov/cassini.

Get Ready To Launch America!

A new era of human spaceflight is about to begin. American astronauts will once again launch on an American rocket from American soil to the International Space Station as part of our Commercial Crew Program! NASA astronauts Bob Behnken and Doug Hurley will fly on SpaceX’s Crew Dragon spacecraft, lifting off on a Falcon 9 rocket at 4:32 p.m. EDT May 27, from Kennedy Space Center in Florida, for an extended stay at the space station for the Demo-2 mission. 

As the final flight test for SpaceX, this mission will validate the company’s crew transportation system, including the launch pad, rocket, spacecraft and operational capabilities. This also will be the first time NASA astronauts will test the spacecraft systems in orbit.

Behnken and Hurley were among the first astronauts to begin working and training on SpaceX’s next-generation human space vehicle and were selected for their extensive test pilot and flight experience, including several missions on the space shuttle.

Behnken will be the joint operations commander for the mission, responsible for activities such as rendezvous, docking and undocking, as well as Demo-2 activities while the spacecraft is docked to the space station.

Hurley will be the spacecraft commander for Demo-2, responsible for activities such as launch, landing and recovery.

Lifting off from Launch Pad 39A atop a specially instrumented Falcon 9 rocket, Crew Dragon will accelerate its two passengers to approximately 17,000 mph and put it on an intercept course with the International Space Station. In about 24 hours, Crew Dragon will be in position to rendezvous and dock with the space station. The spacecraft is designed to do this autonomously but astronauts aboard the spacecraft and the station will be diligently monitoring approach and docking and can take control of the spacecraft if necessary.

The Demo-2 mission will be the final major step before our Commercial Crew Program certifies Crew Dragon for operational, long-duration missions to the space station. This certification and regular operation of Crew Dragon will enable NASA to continue the important research and technology investigations taking place onboard the station, which benefits people on Earth and lays the groundwork for future exploration of the Moon and Mars starting with the agency’s Artemis program, which will land the first woman and the next man on the lunar surface in 2024.

What Are the Bright Spots on Ceres?

Dwarf planet Ceres has more than 130 bright areas, and most of them are associated with impact craters. Now, Ceres has revealed some of its well-kept secrets in two new studies in the journal Nature, thanks to data from our Dawn spacecraft.

Two studies have been looking into the mystery behind these bright areas. One study identifies this bright material as a kind of salt, while the other study suggests the detection of ammonia-rich clays. 

Study authors write that the bright material is consistent with a type of magnesium sulfate called hexahydrite. A different type of magnesium sulfate is familiar on Earth as Epsom salt.

Researchers, using images from Dawn’s framing camera, suggest that these salt-rich areas were left behind when water-ice sublimated in the past. Impacts from asteroids would have unearthed the mixture of ice and salt.

An image of Occator Crater (below) shows the brightest material on Ceres. Occator itself is 60 miles in diameter, and its central pit, covered by this bright material, measures about 6 miles wide. With its sharp rim and walls, it appears to be among the youngest features on the dwarf planet.

In the second nature study, members of the Dawn science team examined the composition of Ceres and found evidence for ammonia-rich clays. Why is this important?

Well, ammonia ice by itself would evaporate on Ceres today, because it is too warm. However, ammonia molecules could be stable if present in combination with other minerals. This raises the possibility that Ceres did not originate in the main asteroid belt between Mars and Jupiter, where it currently resides. But instead, might have formed in the outer solar system! Another idea is that Ceres formed close to its present position, incorporating materials that drifted in from the outer solar system, near the orbit of Neptune, where nitrogen ices are thermally stable.

As of this week, our Dawn spacecraft has reached its final orbital altitude at Ceres (about 240 miles from the surface). In mid-December, it will begin taking observations from this orbit, so be sure to check back for details!

See the Closest Ever Images of the Sun

Solar Orbiter just released its first scientific data — including the closest images ever taken of the Sun.

Launched on February 9, 2020, Solar Orbiter is a collaboration between the European Space Agency and NASA, designed to study the Sun up close. Solar Orbiter completed its first close pass of the Sun on June 15, flying within 48 million miles of the Sun’s surface.

This is already closer to the Sun than any other spacecraft has taken pictures (our Parker Solar Probe mission has flown closer, but it doesn’t take pictures of the Sun). And over the next seven years, Solar Orbiter will inch even closer to the Sun while tilting its orbit above the plane of the planets, to peek at the Sun’s north and south poles, which have never been imaged before.

Here’s some of what Solar Orbiter has seen so far.

The Sun up close

Solar Orbiter’s Extreme Ultraviolet Imager, or EUI, sees the Sun in wavelengths of extreme ultraviolet light that are invisible to our eyes.

EUI captured images showing “campfires” dotting the Sun. These miniature bright spots are over a million times smaller than normal solar flares. They may be the nanoflares, or tiny explosions, long thought to help heat the Sun’s outer atmosphere, or corona, to its temperature 300 times hotter than the Sun’s surface. It will take more data to know for sure, but one thing’s certain: In EUI’s images, these campfires are all over the Sun.

The Polar and Helioseismic Imager, or PHI, maps the Sun’s magnetic field in a variety of ways. These images show several of the measurements PHI makes, including the magnetic field strength and direction and the speed of flow of solar material.

PHI will have its heyday later in the mission, as Solar Orbiter gradually tilts its orbit to 24 degrees above the plane of the planets, giving it a never-before-seen view of the poles. But its first images reveal the busy magnetic field on the solar surface.

Studying space

Solar Orbiter’s instruments don’t just focus on the Sun itself — it also carries instruments that study the space around the Sun and surrounding the spacecraft.

The Solar and Heliospheric Imager, or SoloHi, looks out the side of the Solar Orbiter spacecraft to see the solar wind, dust, and cosmic rays that fill the space between the Sun and the planets. SoloHi captured the relatively faint light reflecting off interplanetary dust known as the zodiacal light, the bright blob of light in the right of the image. Compared to the Sun, the zodiacal light is extremely dim – to see it, SoloHi had to reduce incoming sunlight by a trillion times. The straight bright feature on the very edge of the image is a baffle illuminated by reflections from the spacecraft’s solar array.

This first data release highlights Solar Orbiter’s images, but its in situ instruments also revealed some of their first measurements. The Solar Wind Analyser, or SWA instrument, made the first dedicated measurements of heavy ions — carbon, oxygen, silicon, and iron — in the solar wind from the inner heliosphere.
