SHAKE IT UP! The Orion Exploration Mission-1 crew module was blasted with 141 decibels of acoustic energy to make sure parts don’t come loose when exposed to extreme vibrations experienced at launch. Don’t try this at home.
Wouldn’t it be neat to see a period of the universe’s history that we’ve never seen before? That’s exactly what the James Webb Space Telescope (JWST) will be able to do…plus more!
Specifically, Webb will see the first objects that formed as the universe cooled down after the Big Bang. We don’t know exactly when the universe made the first stars and galaxies – or how for that matter. That is what we are building Webb to help answer.
1. The James Webb Space Telescope is the world’s largest and next premier space observatory. It will extend the discoveries of the Hubble Space telescope and observe the birthplaces of stars, galaxies, planets and life over billions of years.
2. It is named after James Webb, NASA’s second administrator and champion of our science.
3. At 3 stories high and the size of a tennis court, it will be 100 times more powerful than Hubble!
4. It is so big that it has to fold origami-style to fit in the rocket, which is only 5.4 meters wide...And then it will unfurl, segment by segment, once in space.
5. The telescope will observe infrared light with unprecedented sensitivity. It will see the first galaxies born after the Big Bang over 13.5 billion years ago.
6. Webb's infrared cameras are so sensitive they must be shielded from light from the sun, Earth, and moon. The 5-layer sunshield is like having sunblock of SPF 1 million.
7. Webb will orbit the sun 1 million miles from Earth, where the telescope will operate at temperatures below -390 F (-235 C).
8. Webb’s mirrors are coated with a super thin layer of gold only about 1000 atoms thick to optimize their reflectivity in the infrared.
9. Webb will launch from French Guiana in 2018. It is launched near the equator because the faster spin of Earth there gives the rocket an extra push.
10. Webb is an international mission, with contributions from the European Space Agency and Canadian Space Agency. Once operational, scientists from all over the world will be able to use Webb to explore our solar system, planets outside our solar system, stars and galaxies.

Solar eclipses occur when the new moon passes between the Earth and the sun and moon casts a traveling shadow on Earth. A total solar eclipse occurs when the new moon is in just the right position to completely cover the sun’s disk.
This will happen next month on August 21, when the new month completely blocks our view of the sun along a narrow path from Oregon to South Carolina.
It may even be dark enough during the eclipse to see some of the brighter stars and few planets!
Two weeks before or after a solar eclipse, there is often, but not always, a lunar eclipse. This happens because the full moon, the Earth and the sun will be lined up with Earth in the middle.
Beginning July 1, we can see all the moon’s phases.
Many of the Apollo landing sites are on the lit side of the first quarter moon. But to see these sites, you’ll have to rely on images for lunar orbiting spacecraft.
On July 9, the full moon rises at sunset and July 16 is the last quarter. The new moon begins on July 23 and is the phase we’ll look forward to in August, when it will give us the total solar eclipse. The month of July ends with a first quarter moon.
We’ll also have two meteor showers, both of which peak on July 30. The Delta Aquarids will have 25 meteors per hour between midnight and dawn.
The nearby slow and bright Alpha Capricornids per at 5 per hour and often produce fireballs.

Throw open the windows and break out the feather duster, because spring is here and it’s time to do a little cleaning! Fortunately, no one has to tidy up the dust in space — because there’s a lot of it — around 100 tons rain down on Earth alone every day! And there’s even more swirling around the solar system, our Milky Way galaxy, other galaxies and the spaces in between.
By studying the contents of the dust in your house — which can include skin cells, pet fur, furniture fibers, pollen, concrete particles and more — scientists learn a lot about your environment. In the same way, scientists can learn a lot by looking at space dust. Also called cosmic dust, a fleck of space dust is usually smaller than a grain of sand and is made of rock, ice, minerals or organic compounds. Scientists can study cosmic dust to learn about how it formed and how the universe recycles material.
“We are made of star-stuff,” Carl Sagan famously said. And it’s true! When a star dies, it sheds clouds of gas in strong stellar winds or in an explosion called a supernova. As the gas cools, minerals condense. Recent observations by our SOFIA mission suggest that in the wake of a supernova shockwave, dust may form more rapidly than scientists previously thought. These clouds of gas and dust created by the deaths of stars can sprawl across light-years and form new stars — like the Horsehead Nebula pictured above. Disks of dust and gas form around new stars and produce planets, moons, asteroids and comets. Here on Earth, some of that space dust eventually became included in living organisms — like us! Billions of years from now, our Sun will die too. The gas and dust it sheds will be recycled into new stars and planets and so on and so forth, in perpetuity!
Astronomers originally thought dust was a nuisance that got in the way of seeing the objects it surrounded. Dust scatters and absorbs light from stars and emits heat as infrared light. Once we started using infrared telescopes, we began to understand just how important dust is in the universe and how beautiful it can be. The picture of the Andromeda galaxy above was taken in the infrared by our Spitzer Space Telescope and reveals detailed spirals of dust that we can’t see in an optical image.
We also see plenty of dust right here in our solar system. Saturn’s rings are made of mostly ice particles and some dust, but scientists think that dust from meteorites may be darkening the rings over time. Jupiter also has faint dusty rings, although they’re hard to see — Voyager 1 only discovered them when it saw them backlit by the Sun. Astronomers think the rings formed when meteorite impacts on Jupiter’s moons released dust into orbit. The Juno spacecraft took the above picture in 2016 from inside the rings, looking out at the bright star Betelgeuse.

And some space dust you can see from right here on Earth! In spring or autumn, right before sunrise or after sunset, you may be able to catch a glimpse of a hazy cone of light above the horizon created when the Sun’s rays are scattered by dust in the inner solar system. You can see an example in the image above, extending from above the tree on the horizon toward a spectacular view of the Milky Way. This phenomenon is called zodiacal light — and the dust that’s reflecting the sunlight probably comes from icy comets. Those comets were created by the same dusty disk that that formed our planets and eventually you and the dust under your couch!

Our solar system is huge, so let us break it down for you. Here are 5 things to know this week:
1. Dancing with a Star
Our local star, better known as the sun, teems with activity. This month NASA has been tracking regions that burst with magnetic loops. The Solar Dynamics Observatory is one of several space-based assets that keep tabs on the sun daily, watching as charged particles trace the magnetic field, forming bright lines as they emit light in ultraviolet wavelengths.
2. An Idyll for Ida
On Nov. 24, the asteroid Ida makes its closest approach to Earth (at a very safe distance). Ida is the first asteroid found to have its own moon, and the second ever visited by a spacecraft. Its close encounter happened in 1993 as Galileo flew by en route to Jupiter.
3. Moonshine
On Nov. 23, the Cassini spacecraft will fly near Saturn's icy moon Tethys. Several instruments aboard Cassini will collect data, including an eight-frame color image mosaic. Between Nov. 27 and Dec. 2, Cassini will have very limited communications with Earth, because Cassini will enter solar conjunction, when Cassini and Saturn are on the other side of the Sun from Earth.
4. The Moon Will Occult Aldebaran
That may sound ominous, but all it means is that Earth's moon will pass in front of the giant red star Aldebaran on Nov. 26. Aldebaran is the bright "eye" of the constellation Taurus. The event will only be visible in some parts of North America. Details can be found HERE.
5. One Wild Ride, One Year Later
What a year it's been for the Rosetta mission since the Philae lander came to rest on the surface of Comet 67P/Churyumov-Gerasimenko in November 2014. A steady flow of data from the orbiter, together with several days of information sent from the lander, is providing a detailed picture of this remnant from the creation of the solar system.

Our future Mars 2020 rover, seen here as imagined through the eyes of an artist, will search for signs of past microbial life. The mission will take the next step in exploring the Red Planet by not only seeking signs of habitable conditions on Mars in the ancient past, but also searching for signs of past microbial life itself.
The Mars 2020 rover introduces a drill that can collect core samples of the most promising rocks and soils and set them aside on the surface of Mars. A future mission could potentially return these samples to Earth. Mars 2020 is targeted for launch in July/August 2020, aboard an Atlas V 541 rocket from Space Launch Complex 41 at Cape Canaveral Air Force Station in Florida. Learn more.

As OSIRIS-REx closes in on its target destination—asteroid Bennu—anticipation is building for the first-ever, close-up glimpse of this small world. It took thousands of people to come this far. Get to know a few members of the team:
1. Carl Hergenrother, Astronomy Working Group Lead & Strategic and Tactical Scientist
Job Location: University of Arizona, Tucson Expertise: Asteroids & Comets Time on mission: Since before there was a mission Age: 45 Hometown: Oakland, New Jersey
“When you’re observing Bennu with a telescope, you see it as a dot. … So when it actually becomes its own little world, it’s really exciting—and almost a little sad. Up until that point, it can be anything. And now, there it is and that’s it.”
2. Heather Roper, Graphic Designer
Job Location: University of Arizona, Tucson Job Title: Graphic Designer Expertise: Visual Communications Time on mission: 5 years Age: 25 Hometown: Tucson, Arizona
“I really like the challenge of visually depicting the science of the mission and getting to show people things that we can’t see.”
3. Jason Dworkin, Project Scientist
Job Location: NASA’s Goddard Space Flight Center, Greenbelt, Maryland Expertise: Origin-of-life Chemistry Time on mission: Since before there was a mission Age: 49 Hometown: Houston, Texas
"In 10th grade, I had to do a science fair project for biology class. … I wanted to expand on chemistry experiments from old journal papers; but that could have been dangerous. I got in touch with … a pioneering scientist in origin-of-life research and asked for advice. He was worried that I would accidentally injure myself, so he invited me into his lab . . . that helped set my career.”
4. Sara Balram Knutson, Science Operations Lead Engineer
Job Location: University of Arizona, Tucson Expertise: Aerospace Engineering Time on mission: 6 years Age: 31 Hometown: Vacaville, California
“My dad was in the Air Force, so I grew up being a bit of an airplane nerd. When I was in high school, I really liked math, science, and anything having to do with flight. I looked for a field where I could combine all those interests and I found aerospace engineering.”
5. Nancy Neal Jones, Public Affairs Lead
Job Location: NASA’s Goddard Space Flight Center, Greenbelt, Maryland Expertise: Science Communications Time on mission: 7 years Age: 51 Hometown: New York, New York
“We’re going to a pristine asteroid to take a sample to bring to Earth. This means that my children and grandchildren, if they decide to go into the sciences, may have an opportunity analyze the Bennu samples.”
6. Javier Cerna, Communications System Engineer
Job Location: Lockheed Martin Corporation, Littleton, Colorado Expertise: Electrical Engineering Time on mission: Since before there was a mission Age: 37 Hometown: Born in Mexico City, and raised in Los Angeles, and Las Cruces, New Mexico
“One thing we do is evaluate how strong the signal from the spacecraft is—kind of like checking the strength of the WiFi connection. Basically, we’re ensuring that the link from the spacecraft to the ground, and vice versa, stays strong.”
7. Jamie Moore, Contamination Control Engineer
Job Location: Lockheed Martin Corporation, Littleton, Colorado Expertise: Chemistry Time on mission: 5 years Age: 32 Hometown: Apple Valley, Minnesota & Orlando, Florida
“I was there for just about every deployment of the sampling hardware to make sure it was kept clean and to evaluate the tools engineers were using. I even went to Florida with the spacecraft to make sure it stayed clean until launch.”
8. Mike Moreau, Flight Dynamics System Manager
Job Location: NASA’s Goddard Space Flight Center, Greenbelt, Maryland; Littleton, Colorado Expertise: Mechanical and aerospace engineering Time on mission: 5 years Age: 47 Hometown: Swanton, Vermont
“I grew up on a dairy farm in Vermont, which is a world away from working for NASA. But I can trace a lot of my success as an engineer and a leader back to things that I learned on my dad’s farm.”
9. Johnna L. McDaniel, Contamination Control Specialist
Job Location: NASA’s Kennedy Space Center, Florida Expertise: Anti-Contamination Cleaning Time on Mission: 4 months Age: 53 Hometown: Cocoa, Florida
“The clothing requirements depend on the payload. With OSIRIS-Rex, we could not wear any items made with nylon. This was because they have amino acid-based polymers in them and would have contaminated the spacecraft. I even had a special bucket for mopping.”
10. Annie Hasten, Senior Financial Analyst
Job Location: Lockheed Martin Corporation, Steamboat Springs, Colorado Expertise: Business Time on Mission: 1.5 years Age: 30 Hometown: Littleton, Colorado
“I think it’s a pleasure to work with people who are so intensely passionate about their jobs. These engineers are doing their dream jobs, so you feed off of that positive energy.”
