SpaceX Sends Super Science To Space Station!

Will we need to wear the special glasses all day or just during that 2 hour window where viewing is happening?

Deffinelty do not wear them while driving or walking around as you can’t see anything out of them (they are very very dark). But while you are driving and walking you shouldn’t be looking at the Sun anyway. You only need to wear them while you are looking at the Sun. You can use them any day to view the Sun. In a few years, when the Sun once again becomes more active, you can use these glasses and pinhole projectors to see sunspots! Make sure to check that they are ISO 12312-2 compliant, from a trusted vendor, and not scratched or damaged before using them to look at the Sun. https://eclipse2017.nasa.gov/safety 

Chandra X-Ray Observatory, We Appreciate You

On July 23, 1999, the Space Shuttle Columbia blasted off from the Kennedy Space Center carrying the Chandra X-ray Observatory. In the two decades that have passed, Chandra’s powerful and unique X-ray eyes have contributed to a revolution in our understanding of the cosmos.

Since its launch 20 years ago, Chandra's unrivaled X-ray vision has changed the way we see the universe.

Chandra has captured galaxy clusters – the largest gravitationally bound objects in the universe – in the process of merging.

Chandra has shown us the powerful wind and shock fronts that rumble through star-forming systems.

And a star school, so to speak -- home to thousands of the Milky Way's biggest and brightest.

Carl Sagan said, "We are made of star-stuff." It's true. Most of the elements necessary for life are forged inside stars and blasted into interstellar space by supernovas. Chandra has tracked them.

Thank you Chandra X-Ray! To more adventures with you!

Check out Chandra’s 20th anniversary page to see how they are celebrating.

Stretched Loops: When an active region rotated over to the edge of the sun, it presented us with a nice profile view of its elongated loops stretching and swaying above it (March 8/9, 2017). These loops are actually charged particles (made visible in extreme ultraviolet light) swirling along the magnetic field lines of the active region. The video covers about 30 hours of activity. Also of note is a darker twisting mass of plasma to the left of the active region being pulled and spun about by magnetic forces.

NASA Communications and Navigation in 2021: Top 10 Iconic Moments

Did you know NASA uses global networks of antennas and relay satellites to talk with astronauts and spacecraft?

Our space communications and navigation community has had an incredible year! From supporting science and exploration missions to developing cutting-edge tech, here are some of the team’s most impactful accomplishments of 2021.

1. We launched a revolutionary tech demo, the Laser Communications Relay Demonstration, which will showcase the benefits of using infrared laser links to send data from space. Laser communications systems can offer 10 to 100 times more data per second than traditional radio! You can learn more about the mission in a new season of our podcast, The Invisible Network.

2. Planetary radars observed their 1,000th near-Earth asteroid since 1968! Our Deep Space Network plays a critical role in detecting near-Earth asteroids, using radar to spot them. These radar detections help definitively predict if an asteroid is going to hit Earth, or if it’s just going to pass close by.

3. We used lessons learned developing communications services for the Moon to address digital inequality on Earth. Folks at our Glenn Research Center in Cleveland examined how lunar network approaches could address technical challenges to Wi-Fi connectivity in their local community.

4. Our Search and Rescue office participated in dress rehearsals for the Artemis I mission to the Moon! They tested critical distress technologies that will help locate Artemis astronauts in the unlikely event they need to leave the Orion capsule and enter open water before recovery teams can reach them.

5. With high international participation, we hosted a virtual workshop on cognitive communications at our Glenn Research Center in Cleveland, Ohio. Cognitive communications employs artificial intelligence and machine learning in radio systems to provide a host of benefits to user missions!

6. We celebrated the 100th birthday of the creator of Star Trek, the late Gene Roddenberry. The event featured Roddenberry’s son Rod, NASA administrator Bill Nelson, and Star Trek actor George Takei. Following the program, our Deep Space Network broadcast Gene’s 1976 remarks on diversity and inclusion toward star system 40 Eridani — home to the planet Vulcan in Star Trek lore. Signals from the broadcast will arrive there in 16.5 years.

7. We worked with the aerospace community to refine our LunaNet architecture for lunar communications and navigation services! LunaNet will leverage innovative networking techniques, standards, and an extensible framework to rapidly expand network capabilities at the Moon for Artemis. This framework will allow industry, academia, and international partners to build and operate LunaNet nodes alongside us.

8. Our Deep Space Network welcomed a brand new satellite dish into the family! Called Deep Space Station 56, or DSS-56, the 112-foot-wide (34-meter) dish is now online and ready to communicate for a variety of uses, including missions at the Moon and Mars.

9. Our Near Space Network engaged with over 200 commercial aerospace companies! They’re working toward a new paradigm where NASA missions near Earth can rely on a blend of government and commercial space communications infrastructure to meet their needs.

10. Our 10th item on the list isn’t a single moment, but the continued support our communications networks provided missions throughout 2021. Whether it was a Commercial Crew mission to the International Space Station or the Perseverance Rover’s touchdown on Mars, our Near Space Network and Deep Space Network were there to empower mission success!

Crab Nebula in technicolor! This new composite view combines data from five different telescopes, showing the celestial object in multiple kinds of light.

The video starts with a composite image of the Crab Nebula, a supernova remnant that was assembled by combining data from five telescopes spanning nearly the entire breadth of the electromagnetic spectrum: the Very Large Array, the Spitzer Space Telescope, the Hubble Space Telescope, the XMM-Newton Observatory, and the Chandra X-ray Observatory. 

It then dissolves to the red-colored radio-light view that shows how a neutron star’s fierce “wind” of charged particles from the central neutron star energized the nebula, causing it to emit the radio waves. 

The yellow-colored infrared image includes the glow of dust particles absorbing ultraviolet and visible light. 

The green-colored Hubble visible-light image offers a very sharp view of hot filamentary structures that permeate this nebula. 

The blue-colored ultraviolet image and the purple-colored X-ray image shows the effect of an energetic cloud of electrons driven by a rapidly rotating neutron star at the center of the nebula.

Juno: Exploring Jupiter’s Intense Radiation

Since 2011, our Juno spacecraft has been heading towards Jupiter, where it will study the gas giant’s atmosphere, aurora, gravity and magnetic field. Along the way, Juno has had to deal with the radiation that permeates space.

All of space is filled with particles, and when these particles get moving at high speeds, they’re called radiation. We study space radiation to better protect spacecraft as they travel through space, as well as to understand how this space environment influences planetary evolution. Once at Jupiter, Juno will have a chance to study one of the most intense radiation environments in our solar system.

Near worlds with magnetic fields – like Earth and Jupiter – these fast-moving particles can get trapped inside the magnetic fields, creating donut-shaped swaths of radiation called radiation belts.

Jupiter’s radiation belts – the glowing areas in the animation below – are especially intense, with particles so energetic that they zip up and down the belts at nearly the speed of light.

Earth also has radiation belts, but they aren’t nearly as intense as Jupiter’s – why? First, Jupiter’s magnetic field is much stronger than Earth’s, meaning that it traps and accelerates faster particles.

Second, while both Earth’s and Jupiter’s radiation belts are populated with particles from space, Jupiter also has a second source of particles – its volcanically active moon Io. Io’s volcanoes constantly release plumes of particles that are energized by Jupiter’s magnetic field. These fast particles get trapped in Jupiter’s radiation belts, making the belts that much stronger and more intense.  

In addition to studying this vast space environment, Juno engineers had to take this intense radiation into consideration when building the spacecraft. The radiation can cause instruments to degrade, interfere with measurements, and can even give the spacecraft itself an electric charge – not good for something with so many sensitive electronics.  

Since we know Jupiter is a harsh radiation environment, we designed Juno with protections in place to keep it safe. Most of Juno’s electronics live inside a half-inch-thick titanium vault, where most of the radiation can’t reach them. We also planned Juno’s orbit to swoop in very close to Jupiter’s surface, underneath the most intense pockets of radiation in Jupiter’s radiation belts.

Juno arrives at Jupiter on July 4th. Throughout its time orbiting the planet, it will send back data on Jupiter’s magnetic field and energetic particles, helping us understand this intense radiation environment better than ever before.

For updates on the Juno mission, follow the spacecraft on Facebook, Twitter, YouTube and Tumblr.

How does it feel to into space for the first time? Like liftoff and leaving earth’s atmosphere? It seems like the world’s terrifying roller coaster, but what’s it really like?

What’s Up for July 2016?

What's Up for July? Use Saturn as your guide to a tour of the summer Milky Way.

Saturn continues to dazzle this month. Its wide rings and golden color provide a nice contrast to nearby Mars and Antares. Below Saturn lies the constellation Scorpius, which really does look like a scorpion! 

Through binoculars or telescopes you'll be able to spot two pretty star clusters: a compact (or globular) cluster, M-4, and an open cluster, M-7. M-7 is known as Ptolemy's cluster. It was observed and cataloged by Greek-Egyptian astronomer Ptolemy in the first century.

Climbing north, you'll be able to spot the teapot shape which forms part of the constellation Sagittarius. The center of the Milky Way is easy to see. It looks like bright steam rising from the teapot's spout. 

With difficulty, a good star chart and a medium-sized telescope you can locate faint Pluto in the "teaspoon" adjacent to the teapot.

A binocular tour of this center core of the Milky Way reveals many beautiful summer sky objects. We first encounter the Eagle Nebula, M-16. Part of this nebula is featured in the famous and beautiful "Pillars of Creation" images taken by our Hubble Space Telescope.

You'll have to stay up later to see the northern Milky Way constellations, which are better placed for viewing later in the summer and fall. Cygnus the swan features the prettiest supernova remnant in the entire sky, the Veil Nebula. It's too big to fit in one eyepiece view, but luckily there are three sections of it. 

Look between Aquila and Cygnus to find three tiny constellations: Delphinus the dolphin, Vulpecula the fox and Lyra the lyre (or harp). M-57, the Ring Nebula, is the remains from a shell of ionized gas expelled by a red giant star into the surrounding interstellar medium. It's pretty, too! Look in Vulpecula for the Dumbbell, another planetary nebula.

We'll end our summer tour with Lacerta the lizard and Draco the Dragon. Lacerta is home to a star with an extrasolar planet in its orbit, and Draco, facing away from the center of our Milky Way, is a treasure trove of distant galaxies to catch in your telescope.
