What’s Up for April 2017

Jupiter, the king of the planets, is visible all night long, and the Lyrids meteor shower peaks on April 22.

On April 7, Jupiter--the king of planets--reaches opposition, when it shines brightest and appears largest. 

Jupiter will be almost directly overhead at midnight.

This is also a great time to observe the planet’s Galilean moons--Io, Ganymeade, Europa and Callisto. They can be easily seen through binoculars.

With binoculars, you can even see the Great Red Spot as the storm transits the planet every ten hours.

Looking east on April 22, look to the skies for the Summer Triangle, consisting of Deneb, in Cygnus, the Swan; Altair in Aquila, the Eagle; and Vega, in Lyre(the Harp).

Get ready for the Lyrids, the year’s second major meteor shower, as it pierces the Summer Triangle in the early morning hours of April 22. Since the shower begins close to the new moon, expect excellent almost moonless viewing conditions.

What is Artemis I?

On November 14, NASA is set to launch the uncrewed Artemis I flight test to the Moon and back. Artemis I is the first integrated flight test of the Space Launch System (SLS) rocket, the Orion spacecraft, and Exploration Ground Systems at NASA’s Kennedy Space Center in Florida. These are the same systems that will bring future Artemis astronauts to the Moon.

Standing 322 feet (98 meters) tall, the SLS rocket comprises of a core stage, an upper stage, two solid boosters, and four RS-25 engines. The SLS rocket is the most powerful rocket in the world, able to carry 59,500 pounds (27 metric tons) of payloads to deep space — more than any other vehicle. With its unprecedented power, SLS is the only rocket that can send the Orion spacecraft, astronauts, and cargo directly to the Moon on a single mission.

Before launch, Artemis I has some big help: the Vehicle Assembly Building (VAB) at KSC is the largest single-story building in the world. The VAB was constructed for the assembly of the Apollo/Saturn V Moon rocket, and this is where the SLS rocket is assembled, maintained, and integrated with the Orion spacecraft. 

The mobile launcher is used to assemble, process, and launch the SLS rocket and Orion spacecraft. The massive structure consists of a two-story base and a tower equipped with a number of connection lines to provide the rocket and spacecraft with power, communications, coolant, and fuel prior to launch.

Capable of carrying 18 million pounds (8.2 million kg) and the size of a baseball infield, crawler-transporter 2 will transport SLS and Orion the 4.2 miles (6.8 km) to Launch Pad 39B. This historic launch pad was where the Apollo 10 mission lifted off from on May 18, 1969, to rehearse the first Moon landing.

During the launch, SLS will generate around 8.8 million pounds (~4.0 million kg) of thrust, propelling the Orion spacecraft into Earth’s orbit. Then, Orion will perform a Trans Lunar Injection to begin the path to the Moon. The spacecraft will orbit the Moon, traveling 40,000 miles beyond the far side of the Moon — farther than any human-rated spacecraft has ever flown.

The Orion spacecraft is designed to carry astronauts on deep space missions farther than ever before. Orion contains the habitable volume of about two minivans, enough living space for four people for up to 21 days. Future astronauts will be able to prepare food, exercise, and yes, have a bathroom. Orion also has a launch abort system to keep astronauts safe if an emergency happens during launch, and a European-built service module that fuels and propels the spacecraft.

While the Artemis I flight test is uncrewed, the Orion spacecraft will not be empty: there will be three manikins aboard the vehicle. Commander Moonikin Campos will be sitting in the commander’s seat, collecting data on the vibrations and accelerations future astronauts will experience on the journey to the Moon. He is joined with two phantom torsos, Helga and Zohar, in a partnership with the German Aerospace Center and Israeli Space Agency to test a radiation protection vest.

A host of shoebox-sized satellites called CubeSats help enable science and technology experiments that could enhance our understanding of deep space travel and the Moon while providing critical information for future Artemis missions.

At the end of the four-week mission, the Orion spacecraft will return to Earth. Orion will travel at 25,000 mph (40,000 km per hour) before slowing down to 300 mph (480 km per hour) once it enters the Earth’s atmosphere. After the parachutes deploy, the spacecraft will glide in at approximately 20 mph (32 km per hour) before splashdown about 60 miles (100 km) off the coast of California. NASA’s recovery team and the U.S. Navy will retrieve the Orion spacecraft from the Pacific Ocean.

With the ultimate goal of establishing a long-term presence on the Moon, Artemis I is a critical step as NASA prepares to send humans to Mars and beyond.

5 Space Software Codes We Can Use on Earth

We’ve made some amazingly advanced software for our space missions, from launching rockets to the International Space Station to landing rovers on Mars. But a lot of that software can be applied to other situations here on the ground. We’ve got hundreds of downloadable programs in the NASA Software Catalog available for public use—and they’re all free.

We’ve rounded up five interesting software programs to get your search started.

1. Take a walk on Mars from your living room

Want to walk around Mars from the comfort of your living room? OnSight can help with that. Our engineers and scientists created this mixed reality software to immerse themselves in a visualization of the terrain around the Curiosity rover, so users feel like they are really walking on the Red Planet. The software can be adapted to visualize other locations, which means it could also help us explore places on Earth, like caves and lava fields. No wonder it was awarded NASA’s 2018 Software of the Year! 

2. Enhancing images from space and the doctor’s office

It’s hard to take a perfect picture from space. That’s why our scientists created the Hierarchical Image Segmentation software program – to help us enhance and analyze images taken of Earth from space by the Landsat and Terra missions. But, that isn’t all it can do. Doctors have used the software to analyze medical images, such as X-rays, ultrasounds and mammography images, to reveal important details previously unseen by the human eye.

3. Video game tech helps our engineers build spaceflight hardware

Installing sensitive spaceflight hardware is hardly a time for fun and games. Except when it comes to the Distributed Observer Network, or DON 3.1. This software combines innovative NASA tools with commercial video game technology to train our employees for stressful tasks – like maneuvering important, delicate tools through tight spots when building instruments or spacecraft. DON can be used in many other industries, particularly for overcoming the challenges that face virtual teams collaborating on complex problems.

4. Software helps protect Earth from space junk

Those of us on the ground may imagine space as a peaceful place to float among the stars, but in reality, Earth’s atmosphere is filled with junk. This space debris can cause damage to spacecraft and satellites, including the International Space Station. That’s where the Orbital Debris Engineering Model software program comes in. Thanks to this NASA software, we can study the risks of debris impact to help us protect our orbiting equipment and – more importantly – our planet. Communication companies could use this software to prevent debris damage when launching satellites, saving them a lot of time and money.

5. From exploration missions to your office, this software keeps projects on track

Do you manage complex projects at work? There are a lot of steps and moving pieces in play when it comes to getting a spacecraft from the launchpad into space. Used during the space shuttle missions, the Schedule Test and Assessment Tool 5.0 add-on works with Microsoft Project to automate project data to help us stay on track. It’s one of the more popular programs in our software catalog because it provides quick, clear assessment info that can help with decision making.

These are just a few examples of the software NASA has free and available for the public. To browse the new 2019-2020 catalog online, visit https://software.nasa.gov/.

The Pale Blue Dot and the Golden Record

Almost thirty years ago, on Feb. 14, 1990, our Voyager 1 spacecraft turned back toward its home for one last look. 40 astronomical units (almost 4 billion miles) from the Sun, Voyager snapped the first-ever “family portrait” of our solar system.

One image in particular highlights our own planet’s fragility in the vast cosmic arena that we call home. This image of Earth, a tiny point of light, is contained in a camera artifact that resembles a beam of sunlight.

The late Carl Sagan referred to this image of Earth in the title of his 1994 book, Pale Blue Dot. Sagan wrote: "That's here. That's home. That's us. On it everyone you love, everyone you know, everyone you ever heard of, every human being who ever was, lived out their lives. … There is perhaps no better demonstration of the folly of human conceits than this distant image of our tiny world. To me, it underscores our responsibility to deal more kindly with one another, and to preserve and cherish the pale blue dot, the only home we've ever known.”

We placed a message aboard Voyager 1 and 2 — a kind of time capsule intended to communicate a story of our world to extraterrestrials. The Voyager message is carried by a phonograph record: a 12-inch gold-plated copper disk containing sounds and images selected to portray the diversity of life and culture on Earth.

The Golden Record includes 115 images and a variety of natural sounds, such as those made by surf, wind and thunder, birds, whales and other animals. Musical selections from different cultures and eras were also added, as well as spoken greetings from Earth-people in fifty-five languages and printed messages from President Carter.

The Golden Record represents the whole of humanity, mounted to a feat of human engineering on a long voyage through interstellar space. 

You can listen to the sounds of Earth on the golden record here and take a moment to appreciate our pale blue dot.

9 Ocean Facts You Likely Don’t Know, but Should

Earth is a place dominated by water, mainly oceans. It’s also a place our researchers study to understand life. Trillions of gallons of water flow freely across the surface of our blue-green planet. Ocean’s vibrant ecosystems impact our lives in many ways. 

In celebration of World Oceans Day, here are a few things you might not know about these complex waterways.

1. Why is the ocean blue? 

The way light is absorbed and scattered throughout the ocean determines which colors it takes on. Red, orange, yellow,and green light are absorbed quickly beneath the surface, leaving blue light to be scattered and reflected back. This causes us to see various blue and violet hues.

2. Want a good fishing spot? 

Follow the phytoplankton! These small plant-like organisms are the beginning of the food web for most of the ocean. As phytoplankton grow and multiply, they are eaten by zooplankton, small fish and other animals. Larger animals then eat the smaller ones. The fishing industry identifies good spots by using ocean color images to locate areas rich in phytoplankton. Phytoplankton, as revealed by ocean color, frequently show scientists where ocean currents provide nutrients for plant growth.

3. The ocean is many colors. 

When we look at the ocean from space, we see many different shades of blue. Using instruments that are more sensitive than the human eye, we can measure carefully the fantastic array of colors of the ocean. Different colors may reveal the presence and amount of phytoplankton, sediments and dissolved organic matter.

4. The ocean can be a dark place. 

About 70 percent of the planet is ocean, with an average depth of more than 12,400 feet. Given that light doesn’t penetrate much deeper than 330 feet below the water’s surface (in the clearest water), most of our planet is in a perpetual state of darkness. Although dark, this part of the ocean still supports many forms of life, some of which are fed by sinking phytoplankton. 

5. We study all aspects of ocean life. 

Instruments on satellites in space, hundreds of kilometers above us, can measure many things about the sea: surface winds, sea surface temperature, water color, wave height, and height of the ocean surface.

6. In a gallon of average sea water, there is about 1/2 cup of salt. 

The amount of salt varies depending on location. The Atlantic Ocean is saltier than the Pacific Ocean, for instance. Most of the salt in the ocean is the same kind of salt we put on our food: sodium chloride.

7. A single drop of sea water is teeming with life.  

It will most likely have millions (yes, millions!) of bacteria and viruses, thousands of phytoplankton cells, and even some fish eggs, baby crabs, and small worms. 

8. Where does Earth store freshwater? 

Just 3.5 percent of Earth’s water is fresh—that is, with few salts in it. You can find Earth’s freshwater in our lakes, rivers, and streams, but don’t forget groundwater and glaciers. Over 68 percent of Earth’s freshwater is locked up in ice and glaciers. And another 30 percent is in groundwater. 

9. Phytoplankton are the “lungs of the ocean”.

Just like forests are considered the “lungs of the earth”, phytoplankton is known for providing the same service in the ocean! They consume carbon dioxide, dissolved in the sunlit portion of the ocean, and produce about half of the world’s oxygen.
