What Space Weather Means for You

In space, invisible, fast-moving particles from the Sun and other sources in deep space zip around, their behavior shaped by dynamic electric and magnetic fields. There are so few of these particles that space is considered a vacuum, but what’s there packs a punch. Together, we call all of this invisible activity space weather — and it affects our technology both in space and here on Earth.

This month, two new missions are launching to explore two different kinds of space weather.

Scrambled signals

Many of our communications and navigation systems — like GPS and radio — rely on satellites to transmit their signals. When signals are sent from satellites down to Earth, they pass through a dynamic zone on the upper edge of Earth’s atmosphere called the ionosphere.

Gases in the ionosphere have been cooked into a sea of positive- and negative-charged particles by solar radiation. These electrically charged particles are also mixed in with neutral gases, like the air we breathe. The charged particles respond to electric and magnetic fields, meaning they react to space weather. Regular weather can also affect this part of the atmosphere.

Influenced by this complicated web of factors, structured bubbles of charged gas sometimes form in this part of the atmosphere, particularly near the equator. When signals pass through these bubbles, they can get distorted, causing failed communications or inaccurate GPS fixes.

Right now, it’s hard to predict just when these bubbles will form or how they’ll mess with signals. The two tiny satellites of the E-TBEx mission will try to shed some light on this question.

As these CubeSats fly around Earth, they’ll send radio signals to receiving stations on the ground. Scientists will examine the signals received in order to see whether — and if so, how much — they were jumbled as they traveled through the upper atmosphere and down to Earth.

All together, this information will give scientists a better idea of how these bubbles form and change and how much they disrupt signals — information that could help develop strategies for mitigating these bubbles’ disruptive effects.

Damaged satellites

The high-energy, fast-moving particles that fill space are called radiation. Every single spacecraft — from scientific satellites sprinkled throughout the solar system to the communications satellites responsible for relaying the GPS signals we use every day — must weather the harsh radiation of space.

Strikes from tiny, charged particles can spark memory damage or computer upsets on spacecraft, and over time, degrade hardware. The effects are wide-ranging, but ultimately, radiation can impact important scientific data, or prevent people from getting the proper navigation signals they need.

Space Environment Testbeds — or SET, for short — is our mission to study how to better protect satellites from space radiation.

SET aims its sights on a particular neighborhood of near-Earth space called the slot region: the gap between two of Earth’s vast, doughnut-shaped radiation belts, also known as the Van Allen Belts. The slot region is thought to be calmer than the belts, but known to vary during extreme space weather storms driven by the Sun. How much it changes exactly, and how quickly, remains uncertain.

The slot region is an attractive one for satellites — especially commercial navigation and communications satellites that we use every day — because from about 12,000 miles up, it offers not only a relatively friendly radiation environment, but also a wide view of Earth. During intense magnetic storms, however, energetic particles from the outer belt can surge into the slot region. 

SET will survey the slot region, providing some of the first day-to-day weather measurements of this particular neighborhood in near-Earth space. The mission also studies the fine details of how radiation damages instruments and tests different methods to protect them, helping engineers build parts better suited for spaceflight. Ultimately, SET will help other missions improve their design, engineering and operations to avoid future problems, keeping our space technology running smoothly as possible.

To the moon to stay

How We’re Accelerating Our Missions to the Moon

Our Space Launch System isn’t your average rocket. It is the only rocket that can send our Orion spacecraft, astronauts and supplies to the Moon. To accomplish this mega-feat, it has to be the most powerful rocket ever built. SLS has already marked a series of milestones moving it closer to its first launch, Artemis.

Here are four highlights you need to know about — plus one more just on the horizon.

Counting Down

Earlier this month, Boeing technicians at our Michoud Assembly Facility in New Orleans successfully joined the top part to the core stage with the liquid hydrogen tank. The core stage will provide the most of the power to launch Artemis 1. Our 212-foot-tall core stage, the largest the we have ever built, has five major structural parts. With the addition of the liquid hydrogen tank to the forward join, four of the five parts have been bolted together. Technicians are finishing up the final part — the complex engine section — and plan to bolt it in place later this summer.  

Ready to Rumble

This August, to be exact. That’s when the engines for Artemis 1 will be added to the core stage. Earlier this year, all the engines for the first four SLS flights were updated with controllers, tested and officially cleared “go” for launch. We’ve saved time and money by modifying 16 RS-25 engines from the space shuttle and creating a more powerful version of the solid rocket boosters that launched the shuttle. In April, the last engine from the shuttle program finished up a four-year test series that included 32 tests at our Stennis Space Center near Bay St. Louis, Mississippi. These acceptance tests proved the engines could operate at a higher thrust level necessary for deep space travel and that new, modernized flight controllers —the “brains” of the engine — are ready to send astronauts to the Moon in 2024.

Getting a Boost

Our industry partners have completed the manufacture and checkout of 10 motor segments that will power two of the largest propellant boosters ever built. Just like the engines, these boosters are designed to be fast and powerful. Each booster burns 60 tons of propellant every second, generating a max thrust of 3.6 million pounds for two minutes of pure awesome. The boosters will finish assembly at our Kennedy Space Center in Florida and readied for the rocket’s first launch in 2020. In the meantime, we are well underway in completing the boosters for SLS and Orion’s second flight in 2022.

Come Together

Meanwhile, other parts of the rocket are finished and ready for the ride to the Moon. The final piece of the upper part of the rocket, the launch vehicle stage adapter, will soon head toward Kennedy Space Center in Florida. Two other pieces, including the interim cryogenic propulsion stage that will provide the power in space to send Orion on to the Moon, have already been delivered to Kennedy.

Looking to the Future

Our engineers evaluated thousands of designs before selecting the current SLS rocket design. Now, they are performing critical testing and using lessons learned from current assembly to ensure the initial and future designs are up to the tasks of launching exploration missions for years to come. This real-time evaluation means engineers and technicians are already cutting down on assembly time for future mission hardware, so that we and our partners can stay on target to return humans to the Moon by 2024 — to stay so we can travel on to Mars.
