Touchdown! 

A Soyuz spacecraft is seen as it lands with astronaut Shane Kimbrough of NASA and Russian Flight Engineers Sergey Ryzhikov and Andrey Borisenko near the town of Zhezkazgan, Kazakhstan on Monday, April 10. Kimbrough, Ryzhikov, and Borisenko are returning after 173 days in space onboard the International Space Station. 

While living and working aboard the space station, the crew members contributed to hundreds of experiments in biology, biotechnology, physical science and Earth science aboard the world-class orbiting laboratory. For example, the Microgravity Expanded Stem Cells investigation had crew members observe cell growth and other characteristics in microgravity. 

Results from this investigation could lead to the treatment of diseases and injury in space, and provide a way to improve stem cell production for medical therapies on Earth. Photo Credit: (NASA/Bill Ingalls)

Many thousands of galaxies speckle the black screen. The galaxies cluster in the center of the image where they are larger. Several fuzzy yellow galaxies make up the center of the cluster. These galaxies look like soft glowing dust balls, with no defined structure. Hundreds of streaks surround the center of the cluster, as if someone smudged the galaxies’ light in a circular pattern. Thousands of smaller galaxies dot the whole image, like individual specks of dust. These small galaxies vary in size, shape, and color, ranging from red to blue. The different colors are dispersed randomly across the image — there is no apparent patterning or clustering of red or blue galaxies. Credit: NASA, ESA, CSA, STScI

Observations from both NASA’s James Webb and Hubble space telescopes created this colorful image of galaxy cluster MACS0416. The colors of different galaxies indicate distances, with bluer galaxies being closer and redder galaxies being more distant or dusty. Some galaxies appear as streaks due to gravitational lensing — a warping effect caused by large masses gravitationally bending the space that light travels through.

Like Taylor Swift, Our Universe Has Gone Through Many Different Eras

While Taylor's Eras Tour explores decades of music, our universe’s eras set the stage for life to exist today. By unraveling cosmic history, scientists can investigate how it happened, from the universe’s origin and evolution to its possible fate.

A navy blue rectangle forms the background of an infographic. In the top left corner, it says, “History of the Universe.”  An elongated conical shape spans the width of the image. The smaller end of the horn, beginning at a miniscule point, is on the left side of the image and the wider end is on the right. The outline of the horn quickly expands, tracing out the left end of the horn to be about a quarter of the height of the image. The bell shape gradually grows wider as it approaches the right side of the image. The rightmost side of the horn flares outward like a bell. From the left to the right of the horn are 8 ovals that appear to subdivide it. The first oval contains light blue blobs on a dark blue background. Beneath it, it says, “10^-32 seconds, Inflation, initial expansion.” The second oval contains a light blue fog, blue and white orbs, and short, tightly zig-zagged blue lines. Half the white orbs have plus signs, and half have minus signs on them. Beneath the second oval, it says, “1 microsecond, First Particles, neutrons, protons, and electrons form.” The third oval contains a similar blue fog, but the white and blue orbs are stuck to one another in small clusters with no positive or negative signs. The zig-zagged lines remain. Beneath the third oval, it says, “3 minutes, First Nuclei, helium and hydrogen form.” The fourth oval contains a light blue background with some darker blue speckling on it, like on a fresh brown egg. In front of the background are several small spheres. Each sphere is either surrounded by one or two oval outlines. For the spheres with two ovals, the ovals are the same size but are perpendicular to one another. On each oval, in both cases, is a single dot which intersects with the line of the oval as if it traces an orbital. There are still a couple of zig-zagged lines, though much less than in the previous two ovals. Beneath the fourth oval, it says, “380,000 years, First Light, the first atoms form.” The fifth oval contains a blue camouflage-like pattern with a few white dots. Beneath it, it says, “200 million years, First Stars, gas and dust condense into stars.” The sixth oval contains a similar blue camouflage pattern, though it appears to be more transparent. There are several white dots, more than in the fifth oval, and a few white spiral shapes dispersed throughout. Underneath, it says, “400 million years, Galaxies & Dark Matter, galaxies form in dark matter cradles.” In the seventh oval, the blue camouflage pattern has faded, leaving behind a dark blue background with some very thin fog. There are several white dots and white spirals. Beneath the seventh oval, it says, “10 billion years, Dark Energy, expansion accelerates.” The eighth oval is similar to the seventh oval — it features a dark blue background with some thin haze, tens of white dots of varying size, and several spiral shapes of varying size. However, the eighth oval is considerably larger than the rest of the ovals, as it rests at the very end of the flare of the bell shape. Beneath the eighth oval, it says, “13.8 billion years, Today, humans observe the universe.” Credit: NASA

This infographic outlines the history of the universe.

0 SECONDS | In the beginning, the universe debuted extremely small, hot, and dense

Scientists aren’t sure what exactly existed at the very beginning of the universe, but they think there wasn’t any normal matter or physics. Things probably didn’t behave like we expect them to today.

A small flash of white light appears in the middle of a completely black image. The flash expands rapidly, glowing purple and consuming the entire image. The white light shrinks, returning to a pinprick at the center of the image. As it collapses, purple streams and waves pulse outward from the white light’s center. Alongside the waves flow hundreds of small galaxies — spiral and spherical collections of dots of light. The galaxies race out from the center, starting as miniscule specks and becoming larger blobs and smudges as they draw closer, speckling the screen. Credit: NASA’s Goddard Space Flight Center/CI Lab

Artist's interpretation of the beginning of the universe, with representations of the early cosmos and its expansion.

10^-32 SECONDS | The universe rapidly, fearless-ly inflated

When the universe debuted, it almost immediately became unstable. Space expanded faster than the speed of light during a very brief period known as inflation. Scientists are still exploring what drove this exponential expansion.

1 MICROSECOND | Inflation’s end started the story of us: we wouldn’t be here if inflation continued

When inflation ended, the universe continued to expand, but much slower. All the energy that previously drove the rapid expansion went into light and matter — normal stuff! Small subatomic particles — protons, neutrons, and electrons — now floated around, though the universe was too hot for them to combine and form atoms.

The particles gravitated together, especially in clumpy spots. The push and pull between gravity and the particles’ inability to stick together created oscillations, or sound waves.

In front of a dark blue background, hundreds of small red and blue spheres float around, at varying distances from the viewer. In the middle of the screen, two large red and blue spheres collide in the foreground. As they collide, a white flash of light radiates outward. As it fades, the two spheres become visible again, now stuck together. After the first collision, several similar collisions and white flashes are visible in the background. In the top left corner, a clump with one blue sphere and one red sphere races towards another clump with two red spheres and one blue sphere. They collide and there is a flash of white light. As the light clears, a clump with two red spheres and two blue spheres is visible in its place, and a single red sphere floats away toward the center of the screen. Credit: NASA’s Goddard Space Flight Center

Artist's interpretation of protons and neutrons colliding to form ionized deuterium — a hydrogen isotope with one proton and one neutron — and ionized helium — two protons and two neutrons.

THREE MINUTES | Protons and neutrons combined all too well

After about three minutes, the universe had expanded and cooled enough for protons and neutrons to stick together. This created the very first elements: hydrogen, helium, and very small amounts of lithium and beryllium.

But it was still too hot for electrons to combine with the protons and neutrons. These free electrons floated around in a hot foggy soup that scattered light and made the universe appear dark.

In a fuzzy gray fog, hundreds of medium-sized red spheres and small green spheres wiggle around, never moving farther than one diameter from their original position. Hundreds of glowing blue daggers of light bounce between the different spheres, changing direction when they collide with them. Suddenly, the red and green spheres combine, turning brown. The daggers no longer collide with the spheres and instead race away in every direction into open space. A single glowing blue dagger of light zooms away from the spheres and fog into an open blackness speckled with thousands of tiny stars. Credit: NASA/JPL-Caltech

This animated artist’s concept begins by showing ionized atoms (red blobs), free electrons (green blobs), and photons of light (blue flashes). The ionized atoms scattered light until neutral atoms (shown as brown blobs) formed, clearing the way for light to travel farther through space.

380 THOUSAND YEARS | Neutral atoms formed and left a blank space for light

As the universe expanded and cooled further, electrons joined atoms and made them neutral. With the electron plasma out of the way, some light could travel much farther.

A wide oval stretches across a rectangular black background. The oval is about twice as wide as it is tall. It is covered in speckles of varying colors from blue to yellow and red. The colors group together to form large splotches of reds, oranges, and yellows, as well as other splotches of blues and greens. In the bottom left corner, there is a horizontal rectangle with a spectrum of colors, with blue on the left, yellow in the center, and red on the right. Above the rectangle is a label reading “temperature.” Below the rectangle, on the left side under the blue is a label reading, “cooler.” On the right side, under the red, is a label reading “warmer.” Credit: ESA and the Planck Collaboration

An image of the cosmic microwave background (CMB) across the entire sky, taken by ESA's (European Space Agency) Planck space telescope. The CMB is the oldest light we can observe in the universe. Frozen sound waves are visible as miniscule fluctuations in temperature, shown through blue (colder) and red (warmer) coloring.

As neutral atoms formed, the sound waves created by the push and pull between subatomic particles stopped. The waves froze, leaving ripples that were slightly denser than their surroundings. The excess matter attracted even more matter, both normal and “dark.” Dark matter has gravitational influence on its surroundings but is invisible and does not interact with light.

In front of a navy-blue background, tens of light blue orbs float at varying sizes, representing varying distances from the viewer. There are three large blue orbs in the foreground, with small plus signs at their centers. Several yellow streaks of light race across the screen. As the streaks collide with blue orbs, the orbs flash and grow slightly larger, absorbing the yellow streaks, before returning to their original state. The yellow streaks of light do not re-emerge from the orbs. Credit: NASA’s Goddard Space Flight Center

This animation illustrates the absorption of photons — light particles — by neutral hydrogen atoms.

ALSO 380 THOUSAND YEARS | The universe became dark — call it what you want, but scientists call this time period the Dark Ages 

Other than the cosmic microwave background, there wasn't much light during this era since stars hadn’t formed yet. And what light there was usually didn't make it very far since neutral hydrogen atoms are really good at absorbing light. This kicked off an era known as the cosmic dark ages.

A dense orange fog floats in front of a black background that is just barely visible through the thick fog. There are dozens of glowing purple orbs within the fog, clustered in a circle in the center of the visual. One by one, the purple orbs send out bright white circular flashes of light. Following each flash of light, a white ring expands outward from the center of the orb, before fading away once its diameter reaches about one sixth of the image size. Credit: NASA’s Goddard Space Flight Center 

This animation illustrates the beginning of star formation as gas begins to clump due to gravity. These protostars heat up as material compresses inside them and throw off material at high speeds, creating shockwaves shown here as expanding rings of light.

200 MILLION YEARS | Stars created daylight (that was still blocked by hydrogen atoms)

Over time, denser areas pulled in more and more matter, in some places becoming so heavy it triggered a collapse. When the matter fell inward, it became hot enough for nuclear fusion to start, marking the birth of the first stars!

In front of a black background, there are millions of glowing green dots. They form a fine, wispy web stretching across the image, like old cobwebs that have collected dust. Over time, more dots collect at the vertices of the web. As the web gets thicker and thicker, the vertices grow and start moving towards each other and towards the center. The smaller dots circle the clumps, like bees buzzing around a hive, until they are pulled inward to join them. Eventually, the clumps merge to create a glowing green mass. The central mass ensnares more dots, coercing even those from the farthest reaches of the screen to circle it. Credit: Simulation: Wu, Hahn, Wechsler, Abel (KIPAC), Visualization: Kaehler (KIPAC)

A simulation of dark matter forming structure due to gravity.

400 MILLION YEARS | Dark matter acted like an invisible string tying galaxies together

As the universe expanded, the frozen sound waves created earlier — which now included stars, gas, dust, and more elements produced by stars — stretched and continued attracting more mass. Pulling material together eventually formed the first galaxies, galaxy clusters, and wide-scale, web-like structure. 

A borderless three-dimensional cube rotates from left to right in front of a black background. In the cube are many organic cloud-like blobs. They are primarily purplish blue and black, with the centers being darker than the outsides. In the space between the clouds is a light blue translucent material through which more blobs can be seen further back in the cube. As the cube rotates, the blobs become increasingly red and the blue translucent material becomes increasingly see through. After becoming bright red, the blobs start to fade and become a translucent yellow fog before disappearing completely. As they fade, millions of small yellow-ish stars become visible. The stars dot the cube in every dimension. Credit: M. Alvarez, R. Kaehler and T. Abel 

In this animation, ultraviolet light from stars ionizes hydrogen atoms by breaking off their electrons. Regions already ionized are blue and translucent, areas undergoing ionization are red and white, and regions of neutral gas are dark and opaque.

1 BILLION YEARS | Ultraviolet light from stars made the universe transparent for evermore

The first stars were massive and hot, meaning they burned their fuel supplies quickly and lived short lives. However, they gave off energetic ultraviolet light that helped break apart the neutral hydrogen around the stars and allowed light to travel farther.

An animation on a black rectangular background. On the left of the visual is a graph constructed with blue text and the line on the graph. The y-axis of the graph reads “Expansion Speed.” The x-axis is labeled “Time.” At the origin, the x-axis reads, “10 billion years ago.” Halfway across the x-axis is labeled “7 Billion years ago.” At the end of the x-axis is labeled “now.” On the graph is a line which draws itself out. It starts at the top of the y-axis. It slopes down to the right, linearly, as if it were going to draw a straight line from the top left corner of the graph to the bottom right corner of the graph. Around the 7-billion mark, the line begins to decrease in slope very gradually. Three quarters of the way across the x-axis and three quarters of the way down the y-axis, the line reaches a minimum, before quickly curving upwards. It rapidly slopes upward, reaching one quarter from the top of the y-axis as it reaches the end of the x-axis labeled “now.” At the same time, on the right hand of the visual is a tiny dark blue sphere which holds within it glowing lighter blue spheres — galaxies and stars — and a lighter blue webbing. As the line crawls across the graph, the sphere expands. At first, its swelling gently slows, corresponding to the decreasing line on the graph. As the line reaches its minimum and the slope decreases, the sphere slows down its expansion further. Then, as the line arcs back upward, the sphere expands rapidly until it grows larger than the right half of the image and encroaches on the graph. Credit: NASA's Goddard Space Flight Center

Animation showing a graph of the universe’s expansion over time. While cosmic expansion slowed following the end of inflation, it began picking up the pace around 5 billion years ago. Scientists still aren't sure why.

SOMETIME AFTER 10 BILLION YEARS | Dark energy became dominant, accelerating cosmic expansion and creating a big question…?

By studying the universe’s expansion rate over time, scientists made the shocking discovery that it’s speeding up. They had thought eventually gravity should cause the matter to attract itself and slow down expansion. Some mysterious pressure, dubbed dark energy, seems to be accelerating cosmic expansion. About 10 billion years into the universe’s story, dark energy – whatever it may be – became dominant over matter.

A small blue sphere hangs in front of inky blackness. The lower half of the sphere is shrouded in shadow, making it appear hemispherical. The sphere is a rich blue, with swirling white patterns across it — Earth. In the foreground of the image is a gray horizon, covered in small craters and divots — the Moon. Credit: NASA

An image of Earth rising in the Moon’s sky. Nicknamed “Earthrise,” Apollo 8 astronauts saw this sight during the first crewed mission to the Moon.

13.8 BILLION YEARS | The universe as we know it today: 359,785,714,285.7 fortnights from the beginning

We owe our universe today to each of its unique stages. However, scientists still have many questions about these eras.

Our upcoming Nancy Grace Roman Space Telescope will look back in time to explore cosmic mysteries like dark energy and dark matter – two poorly understood aspects of the universe that govern its evolution and ultimate fate.

Spectacular Death. Spectacular Star. Your Crushed Heart Remains Bright From Afar. You’re Looking At

Spectacular death. Spectacular star. Your crushed heart remains bright from afar. You’re looking at a composite image of the Crab Nebula, located 6,500 light-years away. The white dot in the center — an extremely dense ball of neutrons just 12 miles across but with the same mass as our Sun — is all that remains from a star that exploded in 1054 A.D. Had the blast occurred 50 light-years away, its intense radiation would have wiped out most life forms on Earth.  Spectacular death. Spectacular star. We’re grateful we can admire you from afar.

High (Like 240,000 Miles) Fashion: What Astronauts Wear to the Moon

High (Like 240,000 Miles) Fashion: What Astronauts Wear To The Moon

We call it a spacesuit, almost as if it’s something an astronaut pulls out of the closet. It’s more accurate to think of it as an astronaut’s personal spacecraft: self-contained and functional, with a design focused on letting astronauts work safely in space. Just as we’ve been able to improve rockets, satellites and data systems over 60 years, we’ve made great improvements to spacesuits.

High (Like 240,000 Miles) Fashion: What Astronauts Wear To The Moon

When the first woman and next man step foot on the Moon in 2024, they will be wearing the next generation of spacesuit, called the Exploration Extravehicular Mobility Unit, or xEMU for short. The new suit can be used under different conditions for various tasks, including walking, driving rovers or collecting samples. The design will also allow the suits to be used for spacewalks on the space station, or Gateway – our upcoming spaceship that will orbit the Moon. Future missions to Mars can build on the core suit technologies with additional upgrades for use in the Martian atmosphere and greater gravity.

60 Years of Improvements

image

Even before we had astronauts, pilots were using pressurized suits to fly at high speeds at altitudes where the air was too thin to breathe. Our first spacesuits – shown here worn by the first NASA astronauts in 1959 – were variations of the suit used by Navy test pilots.

image

The Gemini spacesuit – shown here in a photo of astronaut Ed White making the first American spacewalk in 1965  – added a line that could connect the astronaut to the spacecraft for oxygen, and which also served as a tether when they left the capsule for a spacewalk.

image

The Apollo astronauts had to completely separate themselves from the lunar module, so we added a portable life support unit, which the astronauts carried on their backs. The photo above shows the life support system on the suit of Apollo 11 astronaut Buzz Aldrin as he deploys lunar experiments in 1969.

Though the bulky suits weren’t exactly easy to maneuver, astronauts still managed to get their jobs done and enjoy themselves doing it.

A Great Moment in Spacesuit History: Singing on the Moon

What, you wouldn’t sing if you were on the moon?

Different Suits for Different Functions

image

We have used different suits for different purposes. During the Space Shuttle program, astronauts inside the shuttle wore these orange “pumpkin” suits, which were designed to be worn within the cabin. 

image

On spacewalks, special suits – made to be worn only outside the spacecraft – provided high mobility, more flexibility and life support as the astronauts worked in zero gravity.

image

During construction of the International Space Station, we should have issued a hard hat and a pair of steel-toed boots with each suit. Astronauts conducted more than 200 spacewalks as part of building the station, which took place from 1998 until 2011. Above, an astronaut at the end of the shuttle’s robotic arm is maneuvered back into the shuttle’s payload bay with a failed pump during the shuttle’s final flight in 2011.

#MissionAccomplished

image

Spacesuits are rarely the story themselves, but they make it possible for our astronauts to get their jobs done, even when they have to improvise. In the picture above, astronauts on a 1992 space shuttle mission are conducting a spacewalk they hadn’t originally planned on. The crew was originally supposed to use a specially designed grab bar to capture the INTELSAT VI satellite. Two attempts to use the grab bar on two-person spacewalks failed, so we improvised a plan to add a third spacewalker and have all three go outside and literally grab the satellite.

Comin’ in Hot: Seven Things to Know About our New Heat Shield

What goes up, must come down, and from space, without burning up in an atmosphere. That’s why we’re pumped for the Low-Earth Orbit Flight Test of an Inflatable Decelerator, or LOFTID. Launching on Nov. 1, 2022, with the National Oceanic and Atmospheric Administration’s (NOAA) Joint Polar Orbiting Satellite System-2 (JPSS-2) mission, this technology demonstration marks the next step in advancing an innovative heat shield design that could one day be used to land heavy payloads – including humans – on Mars!

Animated GIF of an animation of mission highlights for the Low-Earth Orbit Flight Test of an Inflatable Decelerator (LOFTID). We see the upper stage of the ULA Atlas V rocket reorient and position LOFTID for entry into Earth's atmosphere. The re-entry vehicle spins and separates from the upper stage. The inflated heat shield is scene descending toward Earth and motion lines behind the technology indicate the transmission of data during its flight.

Here are seven things to know about this innovative re-entry system: 

1. LOFTID is the first-ever in-orbit test of this technology. 

Inflatable heat shields, called Hypersonic Inflatable Aerodynamic Decelerators (HIADs), have been in the works for more than a decade. In 2012, the third of the Inflatable Re-entry Vehicle Experiments (IRVE) launched on a suborbital sounding rocket from the Wallops Flight Facility, demonstrating a 3-meter (10-foot) diameter inflatable heat shield.

Engineers at NASA's Langley Research Center are standing next to an orange stack of inflated test rings atop a stand during the final test of the inflation system in Jan. 2022. The inflation system is one component of the LOFTID re-entry vehicle demonstration.

But the LOFTID re-entry vehicle, at 19.7 feet (6 meters) in diameter, will be the largest blunt body aeroshell to ever go through atmospheric entry. Designed to withstand temperatures as high as 2900°F (1600°C), this first-ever in-orbit test of this technology will prove if it can successfully slow down large payloads – such as crewed spacecraft, robotic explorers, and rocket components – enabling them to survive the heat of re-entry at planetary destinations with an atmosphere.

2. You can find out how this tech works in real-time.  

LOFTID is unique in that all operations will happen within a few hours of launch. After the JPSS-2 satellite safely reaches orbit, the LOFTID vehicle will separate from the upper stage of the Atlas V rocket and begin re-entry into Earth’s atmosphere. If all goes as planned, the technology will help the vehicle decelerate from hypersonic (more than 25 times faster than the speed of sound) down to subsonic flight, less than 609 miles per hour for a safe splash down and recovery from the Pacific Ocean. 

While in flight, engineers at NASA’s Langley Research Center will receive location data every 20 seconds and onboard sensors and cameras will record more comprehensive data about the technology’s performance. You can get a behind-the-scenes look at Langley’s Flight Mission Support Center where the LOFTID project team will be monitoring the flight test at NASA.gov/live following the launch.

Graphic of the LOFTID Mission Timeline and Flight Path illustrating the important milestones in the technology demonstration. The background imagery on the left is the launch from Vandenberg Space Force Base in California. From the launchpad, the stages of the launch sequence and separation are identified by different icons and timelines starting with the booster separation, and moving through payload spacecraft separation, the aeroshell inflation and the Centaur upper stage orientation and spin. We see a rendering of the heat shield separating at L+70 minutes and LOFTID beginning its descent toward Earth. We see LOFTID's parachute deployed and its splashdown in the Pacific Ocean depicted at the L+125 minute mark.

3. A lemon-sized capsule ejected into the Pacific Ocean will hold key flight data. 

The LOFTID re-entry vehicle will record both sensor and camera data during its flight. The data will include the temperatures and pressures experienced by the heat shield and will illustrate how well the technology performed during the demonstration.

Although the goal is to retrieve the LOFTID re-entry vehicle after it splashes down in the Pacific Ocean, the team wanted a back-up option just in case they can’t recover it. Enter the tiny yellow package called an ejectable data module (EDM) which will also record flight data. The EDM will be released from the spacecraft at an altitude of about 50,000 feet. It will free fall into the Pacific Ocean off the coast of Hawaii and should land within 10 miles of the spacecraft’s splash down location. A recovery team, that has practiced hide-and-seek of the EDM on land and sea, will use GPS to search an approximately 900-mile area of the Pacific Ocean to find their “lemon.”

Four men are pictured wearing life vests aboard a U.S. Army Landing Craft Utility boat as they conducted a water recovery test of the ejectable data module for the Low-Earth Orbit Flight Test of an Inflatable Decelerator (LOFTID).

4. This heat shield packs a punch. 

Although NASA has historically relied on rigid aeroshells, parachutes, and retro-propulsion (rockets) to decelerate people, vehicles, and hardware during entry, descent, and landing operations, a benefit of inflatable heat shields is that they take up less space in a rocket, allowing more room for other hardware or payloads. LOFTID’s aeroshell has been folded and tightly packed down to 4 by 1.5 feet for launch and stacked in the United Launch Alliance (ULA) Atlas V rocket payload fairing.

Close up of the United Launch Alliance Atlas V payload fairing containing the National Oceanic and Atmospheric Administration’s (NOAA) Joint Polar Satellite System-2 (JPSS-2) as it arrived at the vertical integration facility at Space Launch Complex 3 at Vandenberg Space Force Base (VSFB) in California. We see the hand-painted JPSS-2 mission patch on the top of the fairing, the NOAA and NASA logos beneath, and then LOFTID mission patch underneath.

5. LOFTID is dedicated in honor of one of its innovators.  

LOFTID was developed as a partnership with ULA and is dedicated to the memory of Bernard Kutter, ULA manager of advanced programs, who passed away in August 2020. Kutter was instrumental in advancing the inflatable heat shield design and developing the plan to test the system on an Atlas V rocket. He was an advocate for both space technology and expanding access to space. Kutter’s NASA and ULA counterparts agree that LOFTID is unlikely to have made it to space without his vision and passion.

6. LOFTID is made of tough stuff. 

Synthetic fibers make up the inflatable structure, braided into tubes that are, by weight, 10 times stronger than steel. The tubes are coiled so that they form the shape of a blunt cone when inflated. The thermal protection system that covers the inflatable structure can survive searing entry temperatures up to 2,900 degrees Fahrenheit. Researchers used the same heat-shielding materials to create a fire shelter prototype for firefighters battling forest fires.

7. You can make your own LOFTID Halloween costume! 

Still looking for an out-of-this world Halloween costume? With a few commonly found materials, like orange pool noodles and duct tape, you can create your own LOFTID costume. However, we make no promises of protecting or slowing you down from becoming the life of the party.

In front of the NASA worm logo on the stone wall outside the Mary W. Jackson NASA Headquarters building in Washington, is a woman wearing the make-your-own LOFTID Halloween costume. She wears black long-sleeved shirt, gloves and pants, and has yellow suspenders holding up a stack of orange pool noodles in the shape of rings meant to represent the inflatable heat shield technology.

Follow @NASA_Technology for the latest updates on LOFTID. Don’t miss our live coverage leading up to launch from the Vandenberg Space Force Base in California. The NASA Edge JPSS-2 Tower Rollback Show airs live on NASA TV and YouTube on Tuesday, Nov. 1 at 12 a.m. EDT, and NASA TV live launch coverage will begin at 4:45 a.m. EDT.
