Have a Happy Halloween with NASA

Attention ghouls and goblins of the galaxy! The season for scares and frights is upon us, so we’ve rounded up a few Halloween resources to capture that festive feeling. Read on for craft ideas, free decoration downloads, a creepy soundtrack, and even costume ideas.

Launch Your Creativity with Space Crafts!

In honor of the completion of our Nancy Grace Roman Space Telescope’s spacecraft — the vehicle that will maneuver the observatory to its place in space and enable it to function once there — we’re bringing you a space craft you can complete at home! Join us for a journey across the cosmos, starting right in your own pantry.

Student Experiments Soar!

Have you ever wondered what it takes to get a technology ready for space? The NASA TechRise Student Challenge gives middle and high school students a chance to do just that – team up with their classmates to design an original science or technology project and bring that idea to life as a payload on a suborbital vehicle.

Since March 2021, with the help of teachers and technical advisors, students across the country have dreamed up experiments with the potential to impact space exploration and collect data about our planet.

So far, more than 180 TechRise experiments have flown on suborbital vehicles that expose them to the conditions of space. Flight testing is a big step along the path of space technology development and scientific discovery.

A Tour of Cosmic Temperatures

We often think of space as “cold,” but its temperature can vary enormously depending on where you visit. If the difference between summer and winter on Earth feels extreme, imagine the range of temperatures between the coldest and hottest places in the universe — it’s trillions of degrees! So let’s take a tour of cosmic temperatures … from the coldest spots to the hottest temperatures yet achieved.

First, a little vocabulary: Astronomers use the Kelvin temperature scale, which is represented by the symbol K. Going up by 1 K is the same as going up 1°C, but the scale begins at 0 K, or -273°C, which is also called absolute zero. This is the temperature where the atoms in stuff stop moving. We’ll measure our temperatures in this tour in kelvins, but also convert them to make them more familiar!

We’ll start on the chilly end of the scale with our CAL (Cold Atom Lab) on the International Space Station, which can chill atoms to within one ten billionth of a degree above 0 K, just a fraction above absolute zero.

25 Years of Exploring the Universe with NASA's Chandra Xray Observatory

On July 23, 1999, the space shuttle Columbia launched into orbit carrying NASA’s Chandra X-ray Observatory. August 26 marked 25 years since Chandra released its first images.

These were the first of more than 25,000 observations Chandra has taken. This year, as NASA celebrates the 25th anniversary of this telescope and the incredible data it has provided, we’re taking a peek at some of its most memorable moments.

This photo contains both flight (flat in the foreground) and qualification assembly (upright in the background) versions of the Solar Array Sun Shield for NASA’s Nancy Grace Roman Space Telescope. These panels will both shade the mission’s instruments and power the observatory.

Double Vision: Why Do Spacecraft Have Twin Parts?

Seeing double? You’re looking at our Nancy Grace Roman Space Telescope’s Solar Array Sun Shield laying flat in pieces in the foreground, and its test version connected and standing upright in the back. The Sun shield will do exactly what it sounds like –– shade the observatory –– and also collect sunlight for energy to power Roman.

These solar panels are twins, just like several of Roman’s other major components. Only one set will actually fly in space as part of the Roman spacecraft…so why do we need two?

Sometimes engineers do major tests to simulate launch and space conditions on a spare. That way, they don’t risk damaging the one that will go on the observatory. It also saves time because the team can do all the testing on the spare while building up the flight version. In the Sun shield’s case, that means fitting the flight version with solar cells and eventually getting the panels integrated onto the spacecraft.

Our Nancy Grace Roman Space Telescope's primary structure (also called the spacecraft bus) moves into the big clean room at our Goddard Space Flight Center (top). While engineers integrate other components onto the spacecraft bus in the clean room, the engineering test unit (also called the structural verification unit) undergoes testing in the centrifuge at Goddard. The centrifuge spins space hardware to ensure it will hold up against the forces of launch.

Engineers at our Goddard Space Flight Center recently tested the Solar Array Sun Shield qualification assembly in a thermal vacuum chamber, which simulates the hot and cold temperatures and low-pressure environment that the panels will experience in space. And since the panels will be stowed for launch, the team practiced deploying them in space-like conditions. They passed all the tests with flying colors!

The qualification panels will soon pass the testing baton to the flight version. After the flight Solar Array Sun Shield is installed on the Roman spacecraft, the whole spacecraft will go through lots of testing to ensure it will hold up during launch and perform as expected in space.

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.

Athletes Go for the Gold with NASA Spinoffs

NASA technology tends to find its way into the sporting world more often than you’d expect. Fitness is important to the space program because astronauts must undergo the extreme g-forces of getting into space and endure the long-term effects of weightlessness on the human body. The agency’s engineering expertise also means that items like shoes and swimsuits can be improved with NASA know-how.

As the 2024 Olympics are in full swing in Paris, here are some of the many NASA-derived technologies that have helped competitive athletes train for the games and made sure they’re properly equipped to win.

The LZR Racer reduces skin friction drag by covering more skin than traditional swimsuits. Multiple pieces of the water-resistant and extremely lightweight LZR Pulse fabric connect at ultrasonically welded seams and incorporate extremely low-profile zippers to keep viscous drag to a minimum.

One Giant Leap for Mankind

Millions of people around the globe will come together for the Paris 2024 Olympic Games later this month to witness a grand event—the culmination of years of training and preparation.

Fifty-five years ago this July, the world was watching as a different history-changing event was unfolding: the Apollo 11 mission was landing humans on the surface of another world for the first time. An estimated 650 million people watched on TV as Neil Armstrong reached the bottom of the ladder of the lunar module on July 20, 1969, and spoke the words, “That’s one small step for [a] man, one giant leap for mankind.”

While the quest to land astronauts on the Moon was born from the space race with the Soviet Union during the Cold War, this moment was an achievement for the whole of humanity. To mark the world-embracing nature of the Moon landing, several tokens of world peace were left on the Moon during the astronauts’ moonwalk.

The SLS (Space Launch System) Core Stage by Numbers

Technicians with NASA and SLS core stage lead contractor Boeing, along with RS-25 engines lead contractor Aerojet Rocketdyne, an L3Harris Technologies company, are nearing a major milestone for the Artemis II mission. The SLS (Space Launch System) rocket’s core stage for Artemis II is fully assembled and will soon be shipped via barge from NASA’s Michoud Assembly Facility in New Orleans to the agency’s Kennedy Space Center in Florida. Once there, it will be prepped for stacking and launch activities.

Get to know the core stage – by the numbers.
