Experience High-Res Science In First 8K Footage From Space

Astronaut Journal Entry - Week 3

Currently, six humans are living and working on the International Space Station, which orbits 250 miles above our planet at 17,500mph. Below you will find a real journal entry, written in space, by NASA astronaut Scott Tingle.

Week three. The time is flying by. The SpaceX Dragon cargo craft is 80% loaded. This has been a big effort for the crew as well as our specialists on the ground. Tracking a large matrix of storage locations, special requirements and loading locations is a nightmare, but our team on the ground made it look easy. 

Our crew is becoming more versatile and now flexes between operations and science tasking with what is seemingly just a flick of a switch. I had the opportunity to set up our Microgravity Science Glovebox for the Trans-Alloy experiment. Unfortunately, the team had to abort the science run due to high temperatures in the glovebox. 

Tomorrow morning, we will remove the science hardware, remove the cooling plugs, and set it all back up again. Reworks like this don’t bother me, and I am happy to do what is needed to reach success. We are on, and sometimes beyond, the frontline of science where lines between science, engineering and operations become very blurry and complex. We have to be flexible!  The International Space Station (ISS) has now entered its 20th year of operations. What an engineering marvel. As with any aging program, we have accumulated an expanse of experience operating in space. As an engineering community, we are much smarter about operating in space than we were 30 years ago when we designed ISS. I will be very encouraged to see our community apply lessons learned as we create new systems to require less training, less maintenance and less logistics.

I’ve managed to take a few moments over the last week to take some pictures of Earth. Sunrises are the most beautiful part of the day. Out of total darkness, a thin blue ring begins to form that highlights the Earth’s circumference. At this moment, you can really see how thin our atmosphere is. Within a few minutes, the sun rises on station and highlights the docked vehicles while Earth just below is still in night’s shadow. A few minutes later, ISS is over brightly-lighted ground and water, providing a fresh view of the features below. The promise of a new day is real!

The crew managed to have a movie night last night, which provided some good fun and camaraderie. This was a welcome break from the busy routine we endure. Unfortunately, today, I woke to hear that astronaut and moonwalker John Young had passed away. And I also learned that a good friend from the Navy had passed away after a challenging battle with cancer. When he learned he had cancer two years ago, he decided to ignite the afterburners and live every day like there was no tomorrow…he was just as successful in his final days as he was in his previous 50 years. To two remarkable American heroes, thank you for all you have sacrificed and thank you for a lifetime of inspiration. Fair winds and following seas.

Here’s What You Need to Know About Near-Earth Objects

Our solar system is littered with asteroids and comets, and sometimes they get a little close to Earth. But no need to worry! This happens all the time. When an asteroid or comet could come close to our planet, it’s known as a near-Earth object – aka NEO.

But how close is “close”?

A near-Earth object is defined as an object that could pass by our Earth within 30 million miles. We begin to keep close watch on objects that could pass within 5 million miles of our planet.

To put that into perspective, our Moon is only 238,900 miles away.

However unlikely an impact is, we want to know about all near-Earth objects. Our Planetary Defense Coordination Office maintains watch for asteroids and comets coming close to Earth. Along with our partners, we discover, catalog and characterize these bodies.

But what if one of these objects posed a threat?

We want to be prepared. That is why we are working on several deflection techniques and technologies to help protect our planet.

So next time that you hear of an asteroid passing “close” to Earth, know that it’s just one of many that we are tracking.

Here are 10 more things you should know about Planetary Defense.

Celestial Mechanics Around the Solar System During December 2019

The dance of planets, moons and spacecraft around the solar system creates a host of rare alignments in late December 2019. Here's what's coming up.

Dec. 21: Winter solstice in the Northern Hemisphere

Dec. 21 is the 2019 winter solstice for the Northern Hemisphere. A solstice marks the point at which Earth's tilt is at the greatest angle to the plane of its orbit, also the point where half of the planet is receiving the longest stretch of daylight and the other the least. There are two solstices a year, in June and December: the summer and winter solstices, respectively, in the Northern Hemisphere.

The winter solstice is the longest night of the year, when that hemisphere of Earth is tilted farthest from the Sun and receives the fewest hours of sunlight in a given year. Starting Dec. 21, the days will get progressively longer until the June solstice for those in the Northern Hemisphere, and vice versa for the Southern Hemisphere.  

Dec. 26: Annular solar eclipse visible in Asia

On Dec. 26, an annular solar eclipse will be visible in parts of Asia. During an annular eclipse, the Moon's apparent size is too small to completely cover the face of the Sun, creating a "ring of fire" around the Moon's edge during the eclipse.

Solar eclipses happen when the Moon lines up just right with the Sun and Earth. Though the Moon orbits Earth about once a month, the tilt in its orbit means that it's relatively rare for the Moon to pass right in line between the Sun and Earth — and those are the conditions that create an eclipse. Depending on the alignment, the Moon can create a partial, total or annular solar eclipse.

On Dec. 26, the Moon will be near perigee, the point in its orbit when it's farthest from Earth. That means its apparent size from Earth is just a bit smaller — and that difference means that it won't completely cover the Sun during the Dec. 26 eclipse. Instead, a ring of the bright solar surface will be visible around the Moon during the point of greatest eclipse. This is called an annular eclipse.

It is never safe to look directly at an annular solar eclipse, because part of the Sun is always visible. If you're in the path of the annular eclipse, be sure to use solar viewing glasses (not sunglasses) or another safe viewing method to watch the eclipse.

Dec. 26: Parker Solar Probe flies by Venus

After the eclipse, more than 100 million miles away from Earth, Parker Solar Probe will pull off a celestial maneuver of its own. On Dec. 26, the spacecraft will perform the second Venus gravity assist of the mission to tighten its orbit around the Sun.

During the seven gravity assists throughout the mission, Parker Solar Probe takes advantage of Venus's gravity to slow down just the right amount at just the right time. Losing some of its energy allows the spacecraft to be drawn closer by the Sun's gravity: It will fly by the Sun's surface at just 11.6 million miles during its next solar flyby on Jan. 29, 2020. During this flyby, Parker Solar Probe will break its own record for closest-ever spacecraft to the Sun and will gather new data to build on the science already being shared from the mission.

Heads-up, Earthlings! The annual Geminid meteor shower has arrived, peaking overnight Dec. 13-14. It's a good time to bundle up! Then, go outside and let the universe blow your mind!

The Geminids are active every December, when Earth passes through a massive trail of dusty debris shed by a weird, rocky object named 3200 Phaethon. The dust and grit burn up when they run into Earth's atmosphere in a flurry of "shooting stars." 

The Geminids can be seen with the naked eye under clear, dark skies over most of the world, though the best view is from the Northern Hemisphere. Observers will see fewer Geminids in the Southern Hemisphere, where the radiant doesn't climb very high over the horizon. Skywatching is easy. Just get away from bright lights and look up in any direction! Give your eyes time to adjust to the dark. Meteors appear all over the sky.

10 Frequently Asked Questions About the James Webb Space Telescope

Got basic questions about the James Webb Space Telescope and what amazing things we’ll learn from it? We’ve got your answers right here! 

The James Webb Space Telescope, or Webb, is our upcoming infrared space observatory, which will launch in 2021. It will spy the first luminous objects that formed in the universe and shed light on how galaxies evolve, how stars and planetary systems are born, and how life could form on other planets.

1. What is the James Webb Space Telescope?

Our James Webb Space Telescope is a giant space telescope that observes infrared light. Rather than a replacement for the Hubble Space Telescope, it’s a scientific successor that will complement and extend its discoveries.

Being able to see longer wavelengths of light than Hubble and having greatly improved sensitivity will let Webb look further back in time to see the first galaxies that formed in the early universe, and to peer inside dust clouds where stars and planetary systems are forming today.

2. What are the most exciting things we will learn?

We have yet to observe the era of our universe’s history when galaxies began to form. 

We have a lot to learn about how galaxies got supermassive black holes in their centers, and we don't really know whether the black holes caused the galaxies to form or vice versa.

We can't see inside dust clouds with high resolution, where stars and planets are being born nearby, but Webb will be able to do just that. 

We don't know how many planetary systems might be hospitable to life, but Webb could tell whether some Earth-like planets have enough water to have oceans.

We don't know much about dark matter or dark energy, but we expect to learn more about where the dark matter is now, and we hope to learn the history of the acceleration of the universe that we attribute to dark energy. 

And then, there are the surprises we can't imagine!

3. Why is Webb an infrared telescope?

By viewing the universe at infrared wavelengths with such sensitivity, Webb will show us things never before seen by any other telescope. For example, it is only at infrared wavelengths that we can see the first stars and galaxies forming after the Big Bang. 

And it is with infrared light that we can see stars and planetary systems forming inside clouds of dust that are opaque to visible light, such as in the above visible and infrared light comparison image of the Carina Nebula.

4. Will Webb take amazing pictures like Hubble? Can Webb see visible light?

YES, Webb will take amazing pictures! We are going to be looking at things we've never seen before and looking at things we have seen before in completely new ways.

The beauty and quality of an astronomical image depends on two things: the sharpness and the number of pixels in the camera. On both of these counts, Webb is very similar to, and in many ways better than, Hubble. 

Additionally Webb can see orange and red visible light. Webb images will be different, but just as beautiful as Hubble's. Above, there is another comparison of infrared and visible light Hubble images, this time of the Monkey Head Nebula.

5. What will Webb's first targets be?

The first targets for Webb will be determined through a process similar to that used for the Hubble Space Telescope and will involve our experts, the European Space Agency (ESA), the Canadian Space Agency (CSA), and scientific community participants.

The first engineering target will come before the first science target and will be used to align the mirror segments and focus the telescope. That will probably be a relatively bright star or possibly a star field.

6. How does Webb compare with Hubble?

Webb is designed to look deeper into space to see the earliest stars and galaxies that formed in the universe and to look deep into nearby dust clouds to study the formation of stars and planets.

In order to do this, Webb has a much larger primary mirror than Hubble (2.5 times larger in diameter, or about 6 times larger in area), giving it more light-gathering power. It also will have infrared instruments with longer wavelength coverage and greatly improved sensitivity than Hubble. 

Finally, Webb will operate much farther from Earth, maintaining its extremely cold operating temperature, stable pointing and higher observing efficiency than with the Earth-orbiting Hubble.

7. What will Webb tell us about planets outside our solar system? Will it take photos of these planets?

Webb will be able to tell us the composition of the atmospheres of planets outside our solar system, aka exoplanets. It will observe planetary atmospheres through the transit technique. A transit is when a planet moves across the disc of its parent star. 

Webb will also carry coronographs to enable photography of exoplanets (planets outside our solar system) near bright stars (if they are big and bright and far from the star), but they will be only "dots," not grand panoramas. Coronographs block the bright light of stars, which could hide nearby objects like exoplanets.

Consider how far away exoplanets are from us, and how small they are by comparison to this distance! We didn’t even know what Pluto really looked like until we were able to send an observatory to fly right near it in 2015, and Pluto is in our own solar system!

8. Will we image objects in our own solar system?

Yes! Webb will be able to observe the planets at or beyond the orbit of Mars, satellites, comets, asteroids and objects in the distant, icy Kuiper Belt.

Many important molecules, ices and minerals have strong characteristic signatures at the wavelengths Webb can observe. 

Webb will also monitor the weather of planets and their moons. 

Because the telescope and instruments have to be kept cold, Webb’s protective sunshield will block the inner solar system from view. This means that the Sun, Earth, Moon, Mercury, and Venus, and of course Sun-grazing comets and many known near-Earth objects cannot be observed.

9. How far back will Webb see? 

Webb will be able to see what the universe looked like around a quarter of a billion years (possibly back to 100 million years) after the Big Bang, when the first stars and galaxies started to form.

10. When will Webb launch and how long is the mission?

Webb will launch in 2021 from French Guiana on a European Space Agency Ariane 5 rocket. 

Webb’s mission lifetime after launch is designed to be at least 5-1/2 years, and could last longer than 10 years. The lifetime is limited by the amount of fuel used for maintaining the orbit, and by the possibility that Webb’s components will degrade over time in the harsh environment of space.

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.

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)

A Laboratory for Star Formation

Location: In the Carina spiral arm of our Milky Way Galaxy

Distance from Earth: About 20,000 light-years

Object type: Nebula and open star cluster

Discovered by: Sir John Herschel in 1834

Imaged here by the Hubble Space Telescope, NGC 3603 is a collection of thousands of large, hot stars, including some of the most massive stars known to us. Scientists categorize it as an “open cluster” because of its spread-out shape and low density of stars. Surrounding the bright star cluster are plumes of interstellar gas and dust, which comprise the nebula part of this cosmic object. New stars are formed from the gaseous material within these clouds! NGC 3603 holds stars at a variety of life stages, making it a laboratory for scientists to study star evolution and formation. Astronomers estimate that star formation in and around the cluster has been occurring for 10 to 20 million years.

Read more information about NGC 3603 here.

Right now, the Hubble Space Telescope is delving into its #StarrySights campaign! Find more star cluster content and breathtaking new images by following along on Hubble’s Twitter, Facebook, and Instagram.

Around the World in Seven Ground Stations

Happy Birthday, Jules Verne!

Considered by many to be the father of science fiction, French novelist Jules Verne takes his readers on a “From the Earth to the Moon,” “Twenty Thousand Leagues Under the Sea” and “Around the World in Eighty Days.” In his honor, let’s take our own journey around the world, exploring seven far-flung ground stations and the communications networks they support. These ground stations downlink data from science and exploration missions, maintaining the critical link from space to ground.

Our Deep Space Network supports far-out missions like Voyager 1, a spacecraft that's now over 13 billion miles from Earth. To communicate that far, the Network uses antennas as large as 230 feet in diameter. The network has ground stations in Pasadena, California; Madrid, Spain; and this one in Canberra, Australia. The ground stations are strategically placed for maximum coverage of the night sky, ensuring that deep space missions can communicate their data back to Earth. Check out that lizard!

Our Space Network uses relay satellites in conjunction with ground stations to provide continuous communications coverage for satellites in low-Earth orbit like the International Space Station, enabling 24/7 connection with astronauts onboard. Spacecraft using the Space Network beam their data to the constellation of Tracking and Data Relay Satellites, which forward that data to the ground. This is a photo of a Space Network ground station in Guam, a U.S. territory. The spherical structures around the antennas are called “radomes” and protect the antennas from the tropical storms!

Optical communications uses lasers to provide missions with higher data rates than radio communications. Optical terminals also offer missions reduced size, weight and power requirements over comparable radio antennas. A smaller system leaves more room for science instruments, a weight reduction can mean a less expensive launch and reduced power allows batteries to last longer. This ground station in Haleakalā, Hawaii, will relay data to California through a groundbreaking optical communications satellite, the Laser Communications Relay Demonstration. The demonstration will show the power and promise of optical communications to support the next generation of science missions.

Antarctica may seem like an odd place for radio antennas, but McMurdo Ground Station is vitally important to our networks. In 2017, we used the McMurdo ground station to demonstrate a new technology called Disruption Tolerant Networking (DTN), sending a selfie from McMurdo to the space station through numerous DTN nodes. DTN protocols allow data to be stored at points along its route that do not have an open connection to the next intermediary, preventing data loss and improving data returns.

This Near Earth Network ground station in Santiago, Chile, might not be our only South American ground station for long. The Near Earth Network is considering Punta Arenas, Chile, as a possible location for Ka-band antennas, which would provide missions with higher data rates. The Near Earth Network is also experimenting with Ka-band arraying, which uses multiple smaller antennas to provide the same capabilities of a larger, Ka-band antenna. Ka-band services will greatly increase the amount of science data we can gather!

If the space station ever has communications trouble, we could communicate with our astronauts through emergency very high frequency (VHF) communications ground stations like this one in Wallops Island, Virginia. VHF offers voice-only, contingency communications for the station and the Soyuz spacecraft, which ferries astronauts to and from the station. We maintain two VHF stations strategically placed to maximize contact with the space station as it orbits above North America. International partners operate VHF stations that provide contacts as the station orbits above Asia and Europe. NASA’s segment of the VHF network recently underwent critical upgrades that improve the reliability and durability of the system.

This beautiful photo captures Near Earth Network antennas in Svalbard, Norway, beneath the glow of the Northern lights, a phenomenon that occurs when charged particles from the Sun interact with various gasses in Earth’s atmosphere. If one were to visit Iceland, one could see these same lights above Snæfellsjökull volcano, featured in Jules Verne’s “A Journey to the Center of the Earth” as the imaginary entrance to a subterranean world.

A lot has changed in the nearly two centuries since Jules Verne was born. Verne’s 1865 novel “From the Earth to the Moon” and its 1870 sequel “Around the Moon” imagine a giant cannon capable of launching three men into lunar orbit. These imaginary astronauts used opera glasses to survey the lunar surface before returning safely to Earth.

Such a story may seem ridiculous in an age where humanity has occupied space for decades and satellites explore distant worlds with increasing regularity, but Verne’s dreams of spaceflight were novel ­– if not revolutionary – at the time. This change in worldview reflects humanity’s inexorable technological progress and our mission at NASA to turn science fiction into science fact.

As the next generation of exploration commences, our ever-evolving communications capabilities rise to meet the demands of missions that dreamers like Verne could hardly imagine.

The seven ground stations featured here were just a taste of our communications infrastructure. To learn more about space communications, visit: https://www.nasa.gov/SCaN
