Roman’s Five-Year Forecast: A Downpour of Data!

Our Nancy Grace Roman Space Telescope recently passed a major review of the ground system, which will make data from the spacecraft available to scientists and the public.

Since the telescope has a gigantic field of view, it will be able to send us tons of data really quickly — about 500 times faster than our Hubble Space Telescope! That means Roman will send back a flood of new information about the cosmos.

Let’s put it into perspective — if we printed out all of Roman’s data as text, the paper would have to hurtle out of the printer at 40,000 miles per hour (64,000 kilometers per hour) to keep up! At that rate, the stack of papers would tower 330 miles (530 kilometers) high after a single day. By the end of Roman’s five-year primary mission, the stack would extend even farther than the Moon! With all this data, Roman will bring all kinds of cosmic treasures to light, from dark matter and dark energy to distant planets and more!

A patchwork of bright, criss-crossing cloud trails was created by ships churning through the Atlantic Ocean off the coast of Portugal and Spain in this image captured by one of our Earth observing satellites. The narrow clouds known as ship tracks, form when water vapor condenses around tiny particles of pollution that ships emit.

Some of the pollution particles generated by ships (especially sulfates) are soluble in water and serve as the seeds around which cloud droplets form. Clouds infused with ship exhaust have more and smaller droplets than unpolluted clouds. Because of this, the light hitting the polluted clouds scatters in many directions, making them appear brighter and thicker than unpolluted marine clouds, which are typically seeded by larger, naturally occurring particles such as sea salt.

10 Things: CubeSats — Going Farther

Now that the MarCOs — a pair of briefcase-sized interplanetary CubeSats — seem to have reached their limit far beyond Mars, we’re looking forward to an expanding era of small, versatile and powerful space-based science machines.

Here are ten ways we’re pushing the limits of miniaturized technology to see  just how far it can take us.

1. MarCO: The Farthest (So Far)

MarCO, short for Mars Cube One, was the first interplanetary mission to use a class of mini-spacecraft called CubeSats.

The MarCOs — nicknamed EVE and WALL-E, after characters from a Pixar film — served as communications relays during InSight's November 2018 Mars landing, beaming back data at each stage of its descent to the Martian surface in near-real time, along with InSight's first image.

WALL-E sent back stunning images of Mars as well, while EVE performed some simple radio science.

All of this was achieved with experimental technology that cost a fraction of what most space missions do: $18.5 million provided by NASA's Jet Propulsion Laboratory in Pasadena, California, which built the CubeSats.

WALL-E was last heard from on Dec. 29; EVE, on Jan. 4. Based on trajectory calculations, WALL-E is currently more than 1 million miles (1.6 million kilometers) past Mars; EVE is farther, almost 2 million miles (3.2 million kilometers) past Mars.

2. What Are CubeSats?

CubeSats were pioneered by California Polytechnic State University in 1999 and quickly became popular tools for students seeking to learn all aspects of spacecraft design and development.

Today, they are opening up space research to public and private entities like never before. With off-the-shelf parts and a compact size that allows them to hitch a ride with other missions — they can, for example, be ejected from the International Space Station, up to six at a time — CubeSats have slashed the cost of satellite development, opening up doors to test new instruments as well as to create constellations of satellites working together.

CubeSats can be flown in swarms, capturing simultaneous, multipoint measurements with identical instruments across a large area. Sampling entire physical systems in this way would drive forward our ability to understand the space environment around us, in the same way multiple weather sensors help us understand global weather systems.

3. Measuring Up

The size and cost of spacecraft vary depending on the application; some are the size of a pint of ice cream while others, like the Hubble Space Telescope, are as big as a school bus.

Small spacecraft (SmallSats) generally have a mass less than 400 pounds (180 kilograms) and are about the size of a large kitchen fridge.

CubeSats are a class of nanosatellites that use a standard size and form factor.  The standard CubeSat size uses a "one unit" or "1U" measuring 10x10x10 centimeters (or about 4x4x4 inches) and is extendable to larger sizes: 1.5, 2, 3, 6, and even 12U.

The Sojourner rover (seen here on Mars in 1997) is an example of small technology that pioneered bigger things. Generations of larger rovers are being built on its success.

4. A Legacy of Small Pathfinders

Not unlike a CubeSat, NASA’s first spacecraft — Explorer 1 — was a small, rudimentary machine. It launched in 1958 and made the first discovery in outer space, the Van Allen radiation belts that surround Earth. It was the birth of the U.S. space program.

In 1997, a mini-rover named Sojourner rolled onto Mars, a trial run for more advanced rovers such as NASA's Spirit, Opportunity and Curiosity.

Innovation often begins with pathfinder technology, said Jakob Van Zyl, director of the Solar System Exploration Directorate at NASA's Jet Propulsion Laboratory. Once engineers prove something can be done, science missions follow.

5. Testing in Space

NASA is continually developing new technologies — technologies that are smaller than ever before, components that could improve our measurements, on-board data processing systems that streamline data retrievals, or new methods for gathering observations. Each new technology is thoroughly tested in a lab, sometimes on aircraft, or even at remote sites across the world. But the space environment is different than Earth. To know how something is going to operate in space, testing in space is the best option.

Sending something unproven to orbit has traditionally been a risky endeavor, but CubeSats have helped to change that. The diminutive satellites typically take less than two years to build. CubeSats are often a secondary payload on many rocket launches, greatly reducing cost. These hitchhikers can be deployed from a rocket or sent to the International Space Station and deployed from orbit.

Because of their quick development time and easy access to space, CubeSats have become the perfect platform for demonstrating how a new technological advancement will perform in orbit.

6. At Work in Earth Orbit

A few recent examples from our home world:

RainCube, a satellite no bigger than a suitcase, is a prototype for a possible fleet of similar CubeSats  that could one day help monitor severe storms, lead to improving the accuracy of weather forecasts and track climate change over time.

IceCube tested instruments for their ability to make space-based measurements of the small, frozen crystals that make up ice clouds. Like other clouds, ice clouds affect Earth’s energy budget by either reflecting or absorbing the Sun’s energy and by affecting the emission of heat from Earth into space. Thus, ice clouds are key variables in weather and climate models.

7. First Dedicated CubeSat Launch

A series of new CubeSats is now in space, conducting a variety of scientific investigations and technology demonstrations following a Dec. 17, 2018 launch from New Zealand — the first time CubeSats have launched for NASA on a rocket designed specifically for small payloads.

This mission included 10 Educational Launch of Nanosatellites (ELaNa)-19 payloads, selected by NASA’s CubeSat Launch Initiative:

CubeSat Compact Radiation Belt Explorer (CeREs) — High energy particle measurement in Earth’s radiation belt

Simulation-to-Flight 1 (STF-1) — Software condensing to support CubeSat implementations

Advanced Electrical Bus (ALBus) — Advances in solar arrays and high capacity batteries

CubeSat Handling Of Multisystem Precision Time Transfer (CHOMPTT) — Navigation plans for exo-planetary implementation

CubeSail — Deployment and control of a solar sail blade

NMTSat — Magnetic field, high altitude plasma density

Rsat — Manipulation of robotic arms

Ionospheric Scintillation Explorer (ISX) — Plasma fluctuations in the upper atmosphere

Shields-1 — Radiation shielding

DaVinci — High School to Grade School STEM education

8. The Little CubeSat That Could

CubeSat technology is still in its infancy, with mission success rates hovering near 50 percent. So, a team of scientists and engineers set out on a quest. Their goal? To build a more resilient CubeSat — one that could handle the inevitable mishaps that bedevil any spacecraft, without going kaput.

They wanted a little CubeSat that could.

They got to work in 2014 and, after three years of development, Dellingr was ready to take flight.

9. Going Farther

There are a handful of proposed NASA missions could take CubeSat technology farther:

CUVE would travel to Venus to investigate a longstanding mystery about the planet’s atmosphere using ultraviolet-sensitive instruments and a novel, carbon-nanotube light-gathering mirror.

Lunar Flashlight would use a laser to search for water ice in permanently shadowed craters on the south pole of Earth’s Moon.

Near-Earth Asteroid Scout, a SmallSat, would use a solar sail to propel it to do science on asteroids that pass close to Earth.

All three spacecraft would hitch rides to space with other missions, a key advantage of these compact science machines.

10. And We’re Just Getting Started

Even if they're never revived, the team considers MarCO a spectacular success.

A number of the critical spare parts for each MarCO will be used in other CubeSat missions. That includes their experimental radios, antennas and propulsion systems. Several of these systems were provided by commercial vendors, making it easier for other CubeSats to use them as well.

More small spacecraft are on the way. NASA is set to launch a variety of new CubeSats in coming years.

"There's big potential in these small packages," said John Baker, the MarCO program manager at JPL. "CubeSats — part of a larger group of spacecraft called SmallSats — are a new platform for space exploration affordable to more than just government agencies."

Flying With Fuel From Plants: The Eco-friendly Way to Go

We eat them. We make medicines out of them. Now we’re learning how to use plants as airplane fuel that helps the environment.

Using biofuels to help power jet engines reduces particle emissions in their exhaust by as much as 50 to 70 percent, according to a new study that bodes well for airline economics and Earth’s atmosphere.

The findings are the result of a cooperative international research program led by NASA and involving agencies from Germany and Canada, and are detailed in a study published in the journal Nature.

Our flight tests collected information about the effects of alternative fuels on engine performance, emissions and aircraft-generated contrails – essentially, human-made clouds - at altitudes flown by commercial airliners. 

The DC-8's four engines burned either JP-8 jet fuel or a 50-50 blend of JP-8 and renewable alternative fuel of hydro processed esters and fatty acids produced from camelina plant oil. Credits: NASA/SSAI Edward Winstead

Contrails are produced by hot aircraft engine exhaust mixing with the cold air that is typical at cruise altitudes several miles above Earth's surface, and are composed primarily of water in the form of ice crystals.

Researchers are interested in contrails because they create clouds that would not normally form in the atmosphere, and are believed to influence Earth’s environment. 

The alternative fuels tested reduced those emissions. That’s important because contrails have a larger impact on Earth’s atmosphere than all the aviation-related carbon dioxide emissions since the first powered flight by the Wright Brothers.

Researchers plan on continuing these studies to understand the benefits of replacing current fuels in aircraft with biofuels.

Discover NASA Technology in Your Life

Have you ever wondered how space exploration impacts you? “Spinoffs” are products and services developed from NASA technology or improved through NASA partnerships. These innovations—first created to help explore space and study Earth—are responsible for billions of dollars in both revenue and saved costs, tens of thousands of jobs created, and for changing the world around us.

Our NASA Home & City interactive web platform allows you to explore some of the spinoff technologies you can find in your everyday life, demonstrating the wider benefits of America’s investments in its space program.

Here are the seven most unexpected items you can find in your homes and cities which were “spun off” from technologies to enable the study and exploration of space.

1. Wireless Headsets

“That’s one small step for man, one giant leap for mankind.” On July 20, 1969, millions were glued to their television sets when NASA astronaut Neil Armstrong offered these famous words via live broadcast, upon becoming the first man to ever step foot on the Moon. This historic transmission was delivered from Armstrong’s headset to the headsets of Mission Control personnel at NASA, and then on to the world.

Improved by the technology that carried Neil Armstrong’s words, more compact and comfortable headsets were developed for airline pilots in the 1960s and '70s. Today those advancements continue to evolve in all forms of communications and telephone equipment. Mobile headsets provide greater efficiency and flexibility for everyone from professionals to video gamers.

2. Water Quality Monitoring

On the International Space Station very little goes to waste. This includes water, which is recovered from every possible source, cleaned and recycled.

Following our development of a simplified bacteria test for water quality on the space station, one engineer created a foundation to distribute test kits suitable for use in rural communities around the world. Water contamination is still a major problem in many places, and the test helps local communities and governments obtain and share water quality data using a smartphone app.

3. Skin Cream

We know that on Earth, gravity is a constant. For astronauts in orbit, however, it’s a different story—and according to a scientist at NASA's Johnson Space Center, studying what happens to bodies in microgravity “can lead to significant new discoveries in human biology for the benefit of humankind.”

As our researchers experimented with replicating microgravity conditions in the lab, they invented a bioreactor that could help simulate conditions that human cells experience in a space-like environment. This allowed them to perform tissue-growth experiments on the ground and in space, and eventually, to consider the question of how to protect human cells from the toxic effects of long-duration space missions.

Now, thanks to this NASA-patented bioreactor, one company uses agents from human cells that produce collagen to enrich its skin cream products. Lab tests have shown the rejuvenating cream to increase skin moisture content by 76 percent and reduce darkness and wrinkles by more than 50 percent.

4. Acoustic Guitars

From its start, NASA has innovated in all branches of aeronautics, which has led to numerous advances in helicopters, including ways to limit vibrations as they fly and advanced composites to build tougher, safer vehicles. 

An industrious helicopter manufacturer that built up its expertise with NASA contracts later used the same special vibration analysis equipment to enhance the sound of acoustic guitars. The company also built the body out of a fiberglass composite used for rotor blades. The resulting instruments are stronger and less expensive to produce than those of traditional rosewood and produce a rich, full sound.

5. Tiny [Mobile] Homes

While the International Space Station is the largest spacecraft ever flown—it's about the size of a football field—living and working space for astronauts is still at a premium. NASA created a studio called the Habitability Design Center to experiment with the interior design of spacecraft to maximize usable space and make scientific research as efficient and effective as possible.

An architect who helped NASA design the interior of the International Space Station launched a company specializing in compact trailers for camping and exploration. Suitable for a full hookup campsite or going completely off-grid, the company's flagship trailer can accommodate two adults and two children for sleeping and can be customized with a range of features including a shower, refrigerator, toilet, and more. And it all fits into a unit light enough to be towed by a four-cylinder car.

6. Blue Light Blocking Ski Goggles

Skiers and snowboarders face extremely bright sunlight, especially when it's reflected off the white snow. That can make it hard to see, and not just because of glare. The blue in sunlight makes it more difficult to discern colors at the edge of the visible light spectrum, like reds. A NASA-designed filter used in snow goggles helps block up to 95 percent of blue light, making it easier for people on the slopes to see the terrain clearly.

7. Implants for the Hearing Impaired

Hearing aids, which make sound louder, can only do so much for those who were born or have become deaf. Cochlear implants work in a completely different way, converting sound into digital signals that can be processed by the brain.  And the technology traces back in part to a NASA space shuttle engineer who used skills in electronics instrumentation and his own experiences with hearing loss to develop an early version of the life-changing device.

These are just a few examples of thousands of NASA Spinoff and dual-purpose technologies benefiting the world around us.

Countdown to Launch of Landsat 9

We’re launching Landsat 9 — the ninth in a series of satellite missions from NASA and the U.S. Geological Survey (USGS) that have been collecting images of our planet for almost 50 years. Follow along as we count down to launch!

A normal launch countdown starts at 10, but for Landsat 9, we’re jumping in with L-9!

There are 9 million images in the USGS/NASA Landsat archive! They’re all available for free, for use by scientists, data managers, and anyone else who’s interested. You can even download them!

Landsat 9 won’t be orbiting alone. Working together, Landsat 9 and Landsat 8 will completely image Earth every 8 days! This helps us track changes on the planet’s surface as they happen in near-real-time.

Landsat sees all 7 continents! From Antarctic ice to growing cities to changing forests, Landsat measures land — and coastal regions — all around the globe.

Working in space is really hard. Landsat 6 never made it to orbit, an important reminder that failures can be opportunities to learn and grow. Shortly after the unsuccessful launch, engineers got to work on Landsat 7, which is still collecting data today — 22 years later.

We have 5 decades of Landsat observations, the longest continuous record of Earth’s land surfaces in existence! While building the original Landsat in the 1970s, it would have been hard to imagine that this mission would still be providing crucial data about our planet today.

For each color band collected, Landsat 9 will see 4 times the shades of light as the previous Landsat mission! With more than 16,000 different intensities detected, Landsat 9 will be able to see crucial details on our planet’s surface.

Our eyes detect 3 colors of light: red, green, and blue — and Landsat does too! But Landsat 9 also detects wavelengths that can be combined to measure things our eyes can’t, like crop stress, coral reef health, fires, and more.

There are 2 instruments on Landsat 9! The Operational Land Imager 2 collects light, and works kind of like our eyes — or cameras — to make data-rich images. The Thermal Infrared Sensor 2 measures temperature, helping monitor plant health, fires, and more.

The Landsat program is the result of 1 amazing partnership! For more than 50 years, we’ve worked with the U.S. Geological Survey to design, build, launch, and manage Landsat satellites.

Two agencies working together makes for the longest continuous record of Earth’s surfaces. Now, let’s launch this satellite!
