5 Facts About Earth's Radiation Donuts 🍩

Did you know that our planet is surrounded by giant, donut-shaped clouds of radiation?

Here's what you need to know.

1. The radiation belts are a side effect of Earth's magnetic field

The Van Allen radiation belts exist because fast-moving charged particles get trapped inside Earth's natural magnetic field, forming two concentric donut-shaped clouds of radiation. Other planets with global magnetic fields, like Jupiter, also have radiation belts.

2. The radiation belts were one of our first Space Age discoveries

Earth's radiation belts were first identified in 1958 by Explorer 1, the first U.S. satellite. The inner belt, composed predominantly of protons, and the outer belt, mostly electrons, would come to be named the Van Allen Belts, after James Van Allen, the scientist who led the charge designing the instruments and studying the radiation data from Explorer 1.

3. The Van Allen Probes have spent six years exploring the radiation belts

In 2012, we launched the twin Van Allen Probes to study the radiation belts. Over the past six years, these spacecraft have orbited in and out of the belts, providing brand-new data about how the radiation belts shift and change in response to solar activity and other factors.

4. Surprise! Sometimes there are three radiation belts

Shortly after launch, the Van Allen Probes detected a previously-unknown third radiation belt, created by a bout of strong solar activity. All the extra energy directed towards Earth meant that some particles trapped in our planet's magnetic field were swept out into the usually relatively empty region between the two Van Allen Belts, creating an additional radiation belt.

5. Swan song for the Van Allen Probes

Originally designed for a two-year mission, the Van Allen Probes have spent more than six years collecting data in the harsh radiation environment of the Van Allen Belts. In spring 2019, we're changing their orbit to bring the perigee — the part of the orbit where the spacecraft are closest to Earth — about 190 miles lower. This ensures that the spacecraft will eventually burn up in Earth's atmosphere, instead of orbiting forever and becoming space junk.

Because the Van Allen Probes have proven to be so hardy, they'll continue collecting data throughout the final months of the mission until they run out of fuel. As they skim through the outer reaches of Earth's atmosphere, scientists and engineers will also learn more about how atmospheric oxygen can degrade satellite measurements — information that can help build better satellites in the future.

The Big Build: Artemis I Stacks Up

Our Space Launch System (SLS) rocket is coming together at the agency’s Kennedy Space Center in Florida this summer. Our mighty SLS rocket is set to power the Artemis I mission to send our Orion spacecraft around the Moon. But, before it heads to the Moon, NASA puts it together right here on Earth.

Read on for more on how our Moon rocket for Artemis I will come together this summer:

Get the Base

How do crews assemble a rocket and spacecraft as tall as a skyscraper? The process all starts inside the iconic Vehicle Assembly Building at Kennedy with the mobile launcher. Recognized as a Florida Space Coast landmark, the Vehicle Assembly Building, or VAB, houses special cranes, lifts, and equipment to move and connect the spaceflight hardware together. Orion and all five of the major parts of the Artemis I rocket are already at Kennedy in preparation for launch. Inside the VAB, teams carefully stack and connect the elements to the mobile launcher, which serves as a platform for assembly and, later, for fueling and launching the rocket.

Start with the boosters

Because they carry the entire weight of the rocket and spacecraft, the twin solid rocket boosters for our SLS rocket are the first elements to be stacked on the mobile launcher inside the VAB. Crews with NASA’s Exploration Ground Systems and contractor Jacobs team completed stacking the boosters in March. Each taller than the Statue of Liberty and adorned with the iconic NASA “worm” logo, the five-segment boosters flank either side of the rocket’s core stage and upper stage. At launch, each booster produces more than 3.6 million pounds of thrust in just two minutes to quickly lift the rocket and spacecraft off the pad and to space.

Bring in the core stage

In between the twin solid rocket boosters is the core stage. The stage has two huge liquid propellant tanks, computers that control the rocket’s flight, and four RS-25 engines. Weighing more than 188,000 pounds without fuel and standing 212 feet, the core stage is the largest element of the SLS rocket. To place the core stage in between the two boosters, teams will use a heavy-lift crane to raise and lower the stage into place on the mobile launcher.

On launch day, the core stage’s RS-25 engines produce more than 2 million pounds of thrust and ignite just before the boosters. Together, the boosters and engines produce 8.8 million pounds of thrust to send the SLS and Orion into orbit.

Add the Launch Vehicle Stage Adapter

Once the boosters and core stage are secured, teams add the launch vehicle stage adapter, or LVSA, to the stack. The LVSA is a cone-shaped element that connects the rocket’s core stage and Interim Cryogenic Propulsion Stage (ICPS), or upper stage. The roughly 30-foot LVSA houses and protects the RL10 engine that powers the ICPS. Once teams bolt the LVSA into place on top of the rocket, the diameter of SLS will officially change from a wide base to a more narrow point — much like a change in the shape of a pencil from eraser to point.

Lower the Interim Cryogenic Propulsion Stage into place

Next in the stacking line-up is the Interim Cryogenic Propulsion Stage or ICPS. Like the LVSA, crews will lift and bolt the ICPS into place. To help power our deep space missions and goals, our SLS rocket delivers propulsion in phases. At liftoff, the core stage and solid rocket boosters will propel Artemis I off the launch pad. Once in orbit, the ICPS and its single RL10 engine will provide nearly 25,000 pounds of thrust to send our Orion spacecraft on a precise trajectory to the Moon.

Nearly there with the Orion stage adapter

When the Orion stage adapter crowns the top of the ICPS, you’ll know we’re nearly complete with stacking SLS rocket for Artemis I. The Orion Stage Adapter is more than just a connection point. At five feet in height, the Orion stage adapter may be small, but it holds and carries several small satellites called CubeSats. After Orion separates from the SLS rocket and heads to the Moon, these shoebox-sized payloads are released into space for their own missions to conduct science and technology research vital to deep space exploration. Compared to the rest of the rocket and spacecraft, the Orion stage adapter is the smallest SLS component that’s stacked for Artemis I.

Top it off

Finally, our Orion spacecraft will be placed on top of our Moon rocket inside the VAB. The final piece will be easy to spot as teams recently added the bright red NASA “worm” logotype to the outside of the spacecraft. The Orion spacecraft is much more than just a capsule built to carry crew. It has a launch abort system, which will carry the crew to safety in case of an emergency, and a service module developed by the European Space Agency that will power and propel the spacecraft during its three-week mission. On the uncrewed Artemis I mission, Orion will check out the spacecraft’s critical systems, including navigation, communications systems, and the heat shield needed to support astronauts who will fly on Artemis II and beyond.

Ready for launch!

The path to the pad requires many steps and check lists. Before Artemis I rolls to the launch pad, teams will finalize outfitting and other important assembly work inside the VAB. Once assembled, the integrated SLS rocket and Orion will undergo several final tests and checkouts in the VAB and on the launch pad before it’s readied for launch.

The Artemis I mission is the first in a series of increasingly complex missions that will pave the way for landing the first woman and the first person of color on the Moon. The Space Launch System is the only rocket that can send NASA astronauts aboard NASA’s Orion spacecraft and supplies to the Moon in a single mission.

10 Ways the Webb Telescope ‘Trains’ for Space

The James Webb Space Telescope will peer at the first stars and galaxies as a cosmic time machine, look beyond to distant worlds, and unlock the mysteries of the universe. But before it can do any of those things, it needs to “train” for traveling to its destination — 1 million miles away from Earth!

So how does Webb get ready for space while it’s still on the ground? Practice makes perfect. Different components of the telescope were first tested on their own, but now a fully-assembled Webb is putting all of its training together. Here are 10 types of tests that Webb went through to prepare for its epic journey:

1. Sounding Off

A rocket launch is 100 times more intense and four times louder than a rock concert! (That’s according to Paul Geithner, Webb’s deputy project manager – technical.) To simulate that level of extreme noise, Webb’s full structure was blasted with powerful sound waves during its observatory-level acoustic testing in August.

2. Shaking It Up

Webb will also have to withstand a super-bumpy ride as it launches — like a plane takeoff, but with a lot more shaking! The observatory was carefully folded into its launch position, placed onto a shaker table, and vibrated from 5 to 100 times per second to match the speeds of Webb’s launch vehicle, an Ariane 5 rocket.

3. All Systems Go

In July, Webb performed a rigorous test of its software and electrical systems as a fully connected telescope. Each line of code for Webb was tested and then retested as different lines were combined into Webb’s larger software components. To complete this test, Webb team members were staffed 24 hours a day for 15 consecutive days!

4. Hanging Out

After launch, Webb is designed to unfold (like origami in reverse) from its folded launch position into its operational form. Without recharging, the telescope’s onboard battery would only last a few hours, so it will be up to Webb’s 20-foot solar array to harness the Sun’s energy for all of the telescope’s electrical needs. To mimic the zero-gravity conditions of space, Webb technicians tested the solar array by hanging it sideways.

5. Time to Stretch

The tower connects the upper and lower halves of Webb. Once Webb is in space, the tower will extend 48 inches (1.2 meters) upward to create a gap between the two halves of the telescope. Then all five layers of Webb’s sunshield will slowly unfurl and stretch out, forming what will look like a giant kite in space. Both the tower and sunshield will help different sections of Webb maintain their ideal temperatures.

For these steps, engineers designed an ingenious system of cables, pulleys and weights to counter the effects of Earth’s gravity. 6. Dance of the Mirrors

Unfolding Webb’s mirrors will involve some dance-like choreography. First, a support structure will gracefully unfold to place the circular secondary mirror out in front of the primary mirror. Although small, the secondary mirror will play a big role: focusing light from the primary mirror to send to Webb’s scientific instruments.

Next, Webb’s iconic primary mirror will fully extend so that all 18 hexagonal segments are in view. At 6.5 meters (21 feet 4-inches) across, the mirror’s massive size is key for seeing in sharp detail. Like in tower and sunshield testing, the Webb team offloaded the weight of both mirrors with cables, pulleys and weights so that they unfolded as if weightless in space.

7. Do Not Disturb

Before a plane takeoff, it’s important for us to turn off our cell phones to make sure that their electromagnetic waves won’t interfere with navigation signals. Similarly, Webb had to test that its scientific instruments wouldn’t disrupt the electromagnetic environment of the spacecraft. This way, when we get images back from Webb, we’ll know that we’re seeing actual objects in space instead of possible blips caused by electromagnetic interference. These tests took place in the Electromagnetic Interference (EMI) Lab, which looks like a futuristic sound booth! Instead of absorbing sound, however, the walls of this chamber help keep electromagnetic waves from bouncing around.

8. Phoning Earth

How will Webb know where to go and what to look at? Thanks to Webb’s Ground Segment Tests, we know that we’ll be able to “talk” to Webb after liftoff. In the first six hours after launch, the telescope needs to seamlessly switch between different communication networks and stations located around the world. Flight controllers ran through these complex procedures in fall 2018 to help ensure that launch will be a smooth success.

After Webb reaches its destination, operators will use the Deep Space Network, an international array of giant radio antennas, to relay commands that tell Webb where to look. To test this process when Webb isn’t in space yet, the team used special equipment to imitate the real radio link that will exist between the observatory and the network.

9. Hot and Cold

Between 2017 and 2019, Webb engineers separately tested the two halves of the telescope in different thermal vacuum chambers, which are huge, climate-controlled rooms drained of air to match the vacuum of space. In testing, the spacecraft bus and sunshield half were exposed to both boiling hot and freezing cold temperatures, like the conditions that they’ll encounter during Webb’s journey.

But Webb’s mirrors and instruments will need to be colder than cold to operate! This other half of Webb was tested in the historic Chamber A, which was used to test Apollo Moon mission hardware and specifically upgraded to fit Webb. Over about 100 days, Chamber A was gradually cooled down, held at cryogenic temperatures (about minus 387 F, or minus 232.8 C), and then warmed back up to room temperature.

10. Cosmic Vision

When the Hubble Space Telescope was first sent into space, its images were blurry due to a flaw with its mirror. This error taught us about the importance of comprehensively checking Webb’s “eyes” before the telescope gets out of reach.

Besides training for space survival, Webb also spent time in Chamber A undergoing mirror alignment and optical testing. The team used a piece of test hardware that acted as a source of artificial starlight to verify that light would travel correctly through Webb’s optical system.

Whew! That’s a lot of testing under Webb’s belt! Webb is set to launch in October 2021 from Kourou, French Guiana. But until then, it’s still got plenty of training left, including a final round of deployment tests before being shipped to its launch location.

Solar System: Things to Know This Week

In addition to the Mercury transit of the sun today, there are a few other things you should know about our solar system this week:

1. Mars, Ready for its Close-Up

Mars will soon be closer to Earth than it has been for 11 years, presenting a great opportunity for backyard sky watchers.

2. Fire and Ice

Our spacecraft have an even closer view of Mars, and that fact regularly leads to some intriguing discoveries. The latest: volcanoes may have erupted beneath an ice sheet there billions of years ago. The above image is a mineral map of part of the Martian surface.

3. Icy Hydra

Meanwhile, our New Horizons spacecraft has sent home the first compositional data about Pluto's four small moons. The new data show the surface of Hydra is dominated by nearly pristine water ice--confirming hints that scientists picked up in images showing Hydra's highly reflective surface.

4. Ceres, Ever Sharper

The mission director for our Dawn mission writes, "Ceres, which only last year was hardly more than a fuzzy blob against the stars, is now a richly detailed world, and our portrait grows more elaborate every day."

Exploring an Asteroid Without Leaving Earth

You may remember that back in February, four crew members lived and worked inside our Human Research Exploration Analog (HERA). That crew, made up of 4 women, simulated a 715-day journey to a Near-Earth asteroid. Then in May, a second crew of 4 – this time, 4 men, launched on their simulated journey to that same asteroid.  These 30 day missions help our researchers learn how isolation and close quarters affect individual and group behavior. Studies like this at our Johnson Space Center prepare us for long duration space missions, like a trip to an asteroid or even to Mars. We now have a third crew, living and working inside the HERA. This is the spacecraft’s 11th crew. The mission began on June 11, and will end on August 10.

The crew members are currently living inside this compact, science-making house. But unlike in a normal house, these inhabitants won’t go outside for 30 days. Their communication with the rest of planet Earth will also be very limited, and they won’t have any access to internet. The only people they will talk with regularly are mission control and each other.

The HERA XI crew is made up of 3 men and 1 woman selected from the Johnson Space Center Test Subject Screening (TSS) pool. The crew member selection process is based on a number of criteria, including the same criteria for astronaut selection. The four would-be astronauts are:

• Tess Caswell

• Kyle Foster

• Daniel Surber

• Emmanuel Urquieta

What will they be doing?

The crew will test hardware prototypes to get “the bugs worked out” before they are used in off-Earth missions. They will conduct experiments involving plants, brine shrimp, and creating a piece of equipment with a 3D printer. After their visit to an asteroid, the crew will simulate the processing of soil and rocks they collected virtually. Researchers outside of the spacecraft will collect data regarding team dynamics, conflict resolution and the effects of extended isolation and confinement.

How real is a HERA mission?

When we set up an analog research investigation, we try to mimic as many of the spaceflight conditions as we can. This simulation means that even when communicating with mission control, there will be a delay on all communications ranging from 1 to 5 minutes each way, depending on how far their simulated spacecraft is from Earth.

Obviously we are not in microgravity, so none of the effects of microgravity on the human or the vehicle can be tested. You can simulate isolation to a great degree – although the crew knows they are note really isolated from humanity, the communications delays and ban from social media help them to suspend reality. We emulate confinement and the stress that goes along with it.

Scientists and researchers use analogs like HERA to gather more data for comparison to data collected aboard the space station and from other analogs so they can draw conclusions needed for a real mission to deep space, and one day for a journey to Mars.            

A few other details:

The crew follows a timeline that is similar to one used for the     ISS crew.

They work 16 hours a day, Monday through Friday. This     includes time for daily planning, conferences, meals and exercises.  

They will be growing and taking care of plants and     brine shrimp, which they will analyze and document.

Past HERA crew members wore a sensor that recorded heart rate, distance, motion and sound intensity. When crew members were working together, the sensor would also record their proximity as well, helping investigators learn about team cohesion.

Researchers also learned about how crew members react to stress by recording and analyzing verbal interactions and by analyzing “markers” in blood and saliva samples.

As with the 2 earlier missions this year, this mission will include 22 individual investigations across key human research elements. From psychological to physiological experiments, the crew members will help prepare us for future missions.

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.

Standing 212 feet tall and measuring 27.6 feet in diameter, the SLS core stage is the largest rocket stage NASA has ever built. Due to its size, the hardware must be shipped aboard NASA’s Pegasus barge.

900 miles

Once loaded, the barge – which was updated to accommodate the giant core stage -- will travel 900 miles to Florida across inland and ocean waterways. Once at Kennedy, teams with our Exploration Ground Systems team will complete checkouts for the core stage prior to stacking preparations.

18 Miles + 500 Sensors

As impressive as the core stage is on the outside, it’s also incredible on the inside. The “brains” of the rocket consist of three flight computers and special avionics systems that tell the rocket what to do. This is linked to 18 miles of cabling and more than 500 sensors and systems to help feed fuel and steer the four RS-25 engines.

8.8 million

Speaking of engines… Our SLS Moon rocket generates approximately 8.8 million pounds of thrust at launch. Two million pounds come from the four powerful RS-25 engines at the base of the core stage, while each of the two solid rocket boosters produces a maximum thrust of 3.6 million pounds. Together, the engines and boosters will help launch a crew of four Artemis astronauts inside NASA’s Orion spacecraft beyond Earth orbit to venture around the Moon.

733,000 Gallons

Achieving the powerful thrust required at launch calls for a large amount of fuel - 733,000 gallons, to be precise. The stage has two huge propellant tanks that hold the super-cooled liquid hydrogen and liquid oxygen that make the rocket “go.” A new liquid hydrogen storage sphere has recently been built at Kennedy, which can store 1.25 million gallons of liquid hydrogen.

Four

The number four doesn’t just apply to the RS-25 engines. It’s also the number of astronauts who will fly inside our Orion spacecraft atop our SLS rocket for the first crewed Artemis mission. When NASA astronauts Reid Wiseman, Christina Koch, and Victor Glover along with CSA astronaut Jeremy Hansen launch, they will be the first astronauts returning to the Moon in more than 50 years.

Did somebody say space laser?

We’re set to launch ICESat-2, our most advanced laser instrument of its kind, into orbit around Earth on Sept. 15. The Ice, Cloud and land Elevation Satellite-2 will make critical observations of how ice sheets, glaciers and sea ice are changing over time, helping us better understand how those changes affect people where they live. Here’s 10 numbers to know about this mission:

One Space Laser

There’s only one scientific instrument on ICESat-2, but it’s a marvel. The Advanced Topographic Laser Altimeter System, or ATLAS, measures height by precisely timing how long it takes individual photons of light from a laser to leave the satellite, bounce off Earth, and return to ICESat-2. Hundreds of people at our Goddard Space Flight Center worked to build this smart-car-sized instrument to exacting requirements so that scientists can measure minute changes in our planet’s ice.

Two Types of Ice

Not all ice is the same. Land ice, like the ice sheets in Greenland and Antarctica, or glaciers dotting the Himalayas, builds up as snow falls over centuries and forms compacted layers. When it melts, it can flow into the ocean and raise sea level. Sea ice, on the other hand, forms when ocean water freezes. It can last for years, or a single winter. When sea ice disappears, there is no effect on sea level (think of a melting ice cube in your drink), but it can change climate and weather patterns far beyond the poles.

3-Dimensional Earth

ICESat-2 will measure elevation to see how much glaciers, sea ice and ice sheets are rising or falling. Our fleet of satellites collect detailed images of our planet that show changes to features like ice sheets and forests, and with ICESat-2’s data, scientists can add the third dimension – height – to those portraits of Earth.

Four Seasons, Four Measurements

ICESat-2’s orbit will make 1,387 unique ground tracks around Earth in 91 days – and then start the same ground pattern again at the beginning. This allows the satellite to measure the same ground tracks four times a year and scientists to see how glaciers and other frozen features change with the seasons – including over winter.

532 Nanometer Wavelength

The ATLAS instrument will measure ice with a laser that shines at 532 nanometers – a bright green on the visible spectrum. When these laser photons return to the satellite, they pass through a series of filters that block any light that’s not exactly at this wavelength. This helps the instrument from being swamped with all the other shades of sunlight naturally reflected from Earth.

Six Laser Beams

While the first ICESat satellite (2003-2009) measured ice with a single laser beam, ICESat-2 splits its laser light into six beams – the better to cover more ground (or ice). The arrangement of the beams into three pairs will also allow scientists to assess the slope of the surface they’re measuring.

Seven Kilometers Per Second

ICESat-2 will zoom above the planet at 7 km per second (4.3 miles per second), completing an orbit around Earth in 90 minutes. The orbits have been set to converge at the 88-degree latitude lines around the poles, to focus the data coverage in the region where scientists expect to see the most change.

800-Picosecond Precision

All of those height measurements come from timing the individual laser photons on their 600-mile roundtrip between the satellite and Earth’s surface – a journey that is timed to within 800 picoseconds. That’s a precision of nearly a billionth of a second. Our engineers had to custom build a stopwatch-like device, because no existing timers fit the strict requirements.

Nine Years of Operation IceBridge

As ICESat-2 measures the poles, it adds to our record of ice heights that started with the first ICESat and continued with Operation IceBridge, an airborne mission that has been flying over the Arctic and Antarctic for nine years. The campaign, which bridges the gap between the two satellite missions, has flown since 2009, taking height measurements and documenting the changing ice.

10,000 Pulses a Second

ICESat-2’s laser will fire 10,000 times in one second. The original ICESat fired 40 times a second. More pulses mean more height data. If ICESat-2 flew over a football field, it would take 130 measurements between end zones; its predecessor, on the other hand, would have taken one measurement in each end zone.

And One Bonus Number: 300 Trillion

Each laser pulse ICESat-2 fires contains about 300 trillion photons! Again, the laser instrument is so precise that it can time how long it takes individual photons to return to the satellite to within one billionth of a second.

Are You Ready to #BeTheSpark?

Students - want to modify a NASA Spinoff technology and solve a real word problem?

Our Optimus Prime Spinoff Promotion and Research Challenge, known as OPSPARC for short, is a student challenge that guides teams through various NASA Spinoff technologies that are in their everyday world. The teams use their imagination, creativity, and engineering skills to develop their own ideas for NASA spinoff technology.

Spinoffs are technologies originally created for space and modified into everyday products used here on Earth.

Perhaps the most widely recognized NASA spinoff, memory foam was invented by NASA-funded researchers looking for ways to keep test pilots cushioned during flights. Today, memory foam makes for more comfortable beds, couches and chairs, not to mention better shoes, movie theater seats and even football helmets.

There are more than two-thousand NASA Spinoffs They include memory foam, invisible braces, firefighting equipment, programmable pace makers, artificial limbs, scratch-resistant lenses, aircraft anti-icing systems, endangered species tracking software, cochlear implants, satellite television, long-distance telecommunications, and many, many more.

The deadline has been extended to February 26th for our Mission 3 student challenge. Sign up NOW here: https://opsparc.gsfc.nasa.gov/

Fans of the Hasbro TRANSFORMERS brand will pick up on the play on words between the challenge name, OPSPARC, and the "AllSpark" from the TRANSFORMERS universe. The AllSpark is what gave the TRANSFORMERS robots life and knowledge, which they use to help mankind — just like NASA spinoffs. Students from around the globe will have the opportunity to Be The Spark!
