@aura3700: What's the most beautiful thing you've ever seen while in space?
From an astronauts perspective, what is your opinion on movies like Interstellar and Gravity?
What are Perseid Meteors, and why should you be excited for them this year? Let us tell you!
The Perseid meteor shower is caused by debris from Comet Swift-Tuttle as it swings through the inner solar system and ejects a trail of dust and gravel along its orbit. When the Earth passes through the debris, specs of comet-stuff hit the atmosphere at 140,000 mph and disintegrate in flashes of light. Meteors from this comet are called Perseids because they seem to fly out of the constellation Perseus.
Last year, this meteor shower peaked during a bright “supermoon”, so visibility was reduced. Luckily, forecasters say the show could be especially awesome this year because the Moon is nearly new when the shower peaks on Aug. 12-13.
The best place to view the event is away from city lights around midnight. Under a clear, dark sky forecasters predict meteor rates as high as 100 per hour on peak night. So, get outside, look up and enjoy the show!
If your area has poor visibility on the peak night, we’ve got you covered! We’ll be hosting a live broadcast about the meteor shower from 10 p.m. EDT Wednesday, Aug. 12, to 2 a.m. Thursday, Aug. 13. In addition to footage from our live skycam, the program will highlight the science behind the Perseids, as well as our research related to meteors and comets. Tune in on NASA TV or our UStream Channel.
On July 7, three crew members launched from Earth; headed to their new home on the International Space Station.
Crewmembers Kate Rubins of NASA, Anatoly Ivanishin of Roscosmos and Takuya Onishi of the Japan Aerospace Exploration Agency (JAXA) will spend approximately four months on the orbital complex, returning to Earth in October.

Today is Small Business Saturday, an annual campaign that American Express started back in 2010 on the Saturday after Thanksgiving to support “local places that make our communities strong.”
The U.S. Senate has even taken note by passing a bipartisan resolution recognizing November 25, 2017 as Small Business Saturday: “an opportunity for all Americans to rally behind these local, independently-owned businesses and support the entrepreneurs who keep our families employed.”
Here at NASA, we look to promote and integrate small businesses across the country into the work we do to pioneer the future of space exploration, scientific discovery and aeronautics research.
Our Small Business Innovative Research (SBIR) and Small Business Technology Transfer (STTR) program seeks to fund the research, development and demonstration of innovative technologies that help address space exploration challenges and have significant potential for commercialization. In fiscal year 2017, our program awarded 567 contracts to 277 small businesses and 44 research institutions for a total of $173.5M that will enable our future missions into deep space and advancements in aviation and science, while also benefiting the U.S. economy. This year, the SBIR/STTR program’s Economic Impact Report indicated a $2.74 return for every dollar spent on awards—money well spent!
Our small business partners’ ideas have helped our work become more efficient and have advanced scientific knowledge on the International Space Station. Over 800 small businesses are contributing to the development of our Space Launch System rocket that will carry humans to deep space. SBIR/STTR program awardees are also helping the Curiosity Rover get around Mars and are even preparing the Mars 2020 Rover to search for signs of potential life on the Red Planet.
Small businesses are also contributing to scientific advances here on Earth like helping our satellites get a clearer picture of soil moisture in order to support water management, agriculture, and fire, flood and drought hazard monitoring.
In an effort to improve our understanding of the Arctic and Antarctica, a small business developed a cost-saving unmanned aircraft system that could withstand some of the coldest temperatures on the planet.
Does your small business have a big idea? Your next opportunity to join the SBIR/STTR program starts on January 11, 2018 when our latest solicitation opens.
We’ll be seeking new ideas from small businesses and research institutions for research, development and demonstration of innovative technologies. Go to www.nasa.sbir.gov to learn more.

Look no further than this cozy and relaxing fireplace – complete with four RS-25 rocket engines to fill your hearth with light. (And 8.8 million pounds of thrust to power your party to the Moon.)
These tips are meant for a DSLR or mirrorless camera, but some point-and-shoot cameras with manual controls could be used as well.
The Perseids are dusty remnants of comet 109P/Swift-Tuttle.
Earth passes through the comet’s invisible, multi-billion mile trail of tiny debris each year around August, creating a meteor shower of so-called “shooting stars” as the particles are vaporized in our atmosphere.
Perseid meteors already are streaking across the sky. This year's shower peaks on a moonless summer night -from 4 pm on the 12th until 4 am on the 13th Eastern Daylight Time.

Too much light and it will be hard for your eyes to see fainter meteors, plus your image will get flooded with the glow of light. Turning down the brightness of the camera’s LCD screen will help keep your eyes adjusted to the dark. The peak of the 2018 Perseid meteor shower occurs just after the new moon, meaning a thin crescent will set long before the best viewing hours, leaving hopeful sky watchers with a moonlight-free sky!

Meteor photography requires long exposures, and even the steadiest of hands can’t hold a camera still enough for a clear shot. Heavier tripods help reduce shaking caused by wind and footsteps, but even a lightweight tripod will do. You can always place sandbags against the feet of the tripod to add weight and stability. If you don’t have a tripod, you might be able to prop your camera on or up against something around you, but be sure to secure your camera.

A wide-angle lens will capture more of the sky and give you a greater chance of capturing a meteor in your shot, while a zoom lens captures a smaller area of the sky. The odds of a meteor streaking past that small patch are lower.

A tripod does a great job of reducing most of the shaking your camera experiences, but even the act of pressing the shutter button can blur your extended exposure. Using the self-timer gives you several seconds for any shaking from pressing the shutter button to stop before the shutter is released. A shutter release cable (without a self-timer) eliminates the need to touch the camera at all. And if your camera has wifi capabilities, you might be able to activate the shutter from a mobile device.

At night, autofocus will struggle to find something on which to focus. Setting your focus to infinity will get you close, but chances are you’ll have to take some test images and do some fine tuning. With your camera on a tripod, take a test image lasting a few seconds, then use the camera’s screen to review the image. Zoom in to a star to see how sharp your focus is. If the stars look like fuzzy blobs, make tiny adjustments to the focus and take another test image.
Repeat until you are happy with the result.
If your camera has a zoomable electronic viewfinder or live view option, you might be able to zoom to a star and focus without having to take a test image.
The Perseids appear to radiate from the constellation Perseus, visible in the northern sky soon after sunset this time of year.
Even though we don’t know when or where a single meteor will appear, we do know the general area from which they’ll originate.
Meteor showers get their name based on the point in the sky from which they appear to radiate. In the case of the Perseids, during their peak, they appear to come from the direction of the constellation Perseus in the northern sky.
In this 20-second exposure, a meteor lights up the sky over the top of a mountain ridge near Park City, Utah. Even though this image was captured during the annual Perseid meteor shower, this "shooting star" is probably not one of the Perseid meteors, which originate from material left behind by Comet Swift-Tuttle. Instead, it's likely one of the many bits of rock and dust that randomly fall into the atmosphere on any given night. Credit: NASA/Bill Dunford
As Earth rotates, the stars in the sky appear to move, and if your shutter is open long enough, you might capture some of that movement. If you want to avoid apparent star movement, you can follow the 500 Rule. Take 500 and divide it by the length in millimeters of your lens. The resulting number is the length of time in seconds that you can keep your shutter open before seeing star trails. For example, if you’re using a 20 mm lens, 25 seconds (500 divided by 20) is the longest you can set your exposure time before star trails start to show up in your images.

Once you know the maximum exposure time, you can set your shutter priority to that length and let the camera calculate other settings for your first image. Depending on how the image turns out, you can manually adjust aperture (set it to a lower number if the image is too dark) and ISO (set it to a higher number if the image is too dark) to improve your next images. Changing only one setting at a time will give you a better understanding of how those changes affect your image.

With your camera settings adjusted, capturing that perfect photo is just a matter of time and luck. The highest rate of meteors visible per hour is in the hours after midnight and before dawn. Set up your camera next to a lounge chair or a blanket to witness the wonder of a meteor shower for yourself – and, with any luck, you’ll take home some envy-inducing shots, too!

How has being in space changed your perspective of life on Earth?
On this day in 1972, two NASA astronauts landed on the Moon. Now, 45 years later, we have been instructed to return to the lunar surface.
Today at the White House, President Trump signed the Space Policy Directive 1, a change in national space policy that provides for a U.S.-led program with private sector partners for a human return to the Moon, followed by missions to Mars and beyond.
Among other dignitaries on hand for the signing, were NASA astronauts Sen. Harrison “Jack” Schmitt, Buzz Aldrin, Peggy Whitson and Christina Koch.
Schmitt landed on the moon 45 years to the minute that the policy directive was signed as part of our Apollo 17 mission, and is the most recent living person to have set foot on our lunar neighbor.
Above, at the signing ceremony instructing us to send humans back to the lunar surface, Schmitt shows First Daughter Ivanka Trump the Moon sample he collected in 1972.
The effort signed today will more effectively organize government, private industry and international efforts toward returning humans on the Moon, and will lay the foundation that will eventually enable human exploration of Mars.

On June 24, 2020, NASA announced the agency’s headquarters building in Washington, D.C., was to be named after Mary W. Jackson, the first African American female engineer at NASA.
Jackson’s story — along with those of her colleagues Katherine Johnson, Dorothy Vaughan, and Christine Darden — was popularized with the release of the “Hidden Figures” movie, based on Margot Lee Shetterly’s book by the same name.
Today, as the accomplishments of these women are brought to light, we celebrate them as Modern Figures — hidden no longer. Despite their recent recognition, we cannot forget the challenges that women and BIPOC faced and continue to face in the STEM fields.
Jackson showed talent for math and science at an early age. She was born in 1921 in Hampton, Virginia, and attended the all-Black George P. Phenix Training School where she graduated with honors. She graduated from Hampton Institute (now Hampton University) in 1942 with a bachelor of science degree in both mathematics and physical sciences.
Jackson worked several jobs before arriving at the National Advisory Committee on Aeronautics (NACA), the precursor organization to NASA. She was a teacher, a receptionist, and a bookkeeper — in addition to becoming a mother — before accepting a position with the NACA Langley Aeronautical Laboratory’s segregated West Area Computers in 1951, where her supervisor was Dorothy Vaughan.
After two years in West Computing, Jackson was offered a computing position to work in the 4-foot by 4-foot Supersonic Pressure Tunnel. She was also encouraged to enter a training program that would put her on track to become an engineer — however, she needed special permission from the City of Hampton to take classes in math and physics at then-segregated Hampton High School.
She completed the courses, earned the promotion, and in 1958 became NASA’s first African-American female engineer. That same year, she co-authored her first report, “Effects of Nose Angle and Mach Number on Transition on Cones at Supersonic Speeds.” By 1975, she had authored or co-authored 12 NACA and NASA technical publications — most focused on the behavior of the boundary layer of air around an airplane.
Jackson eventually became frustrated with the lack of management opportunities for women in her field. In 1979, she left engineering to become NASA Langley’s Federal Women’s Program Manager to increase the hiring and promotion of NASA’s female mathematicians, engineers, and scientists.
Not only was she devoted to her career, Jackson was also committed to the advancement of her community. In the 1970s, she helped the students in the Hampton King Street Community Center build their own wind tunnel and run experiments. She and her husband Levi took in young professionals in need of guidance. She was also a Girl Scout troop leader for more than three decades.
Jackson retired from Langley in 1985. Never accepting the status quo, she dedicated her life to breaking barriers for minorities in her field. Her legacy reminds us that inclusion and diversity are needed to live up to NASA’s core values of teamwork and excellence.

This month hosts the best meteor shower of the year and the brightest stars in familiar constellations.
The Geminds peak on the morning of the 14th, and are active from December 4th through the 17th. The peak lasts for a full 24 hours, meaning more worldwide meteor watchers will get to see this spectacle.
Expect to see up to 120 meteors per hour between midnight and 4 a.m. but only from a dark sky. You'll see fewer after moonrise at 3:30 a.m. local time.
In the southern hemisphere, you won't see as many, perhaps 10-20 per hour, because the radiant never rises above the horizon.
Take a moment to enjoy the circle of constellations and their brightest stars around Gemini this month.
Find yellow Capella in the constellation Auriga.
Next-going clockwise--at 1 o'clock find Taurus and bright reddish Aldebaran, plus the Pleiades.
At two, familiar Orion, with red Betelguese, blue-white Rigel, and the three famous belt stars in-between the two.
Next comes Leo, and its white lionhearted star, Regulus at 7 o'clock.
Another familiar constellation Ursa Major completes the view at 9 o'clock.
There's a second meteor shower in December, the Ursids, radiating from Ursa Minor, the Little Dipper. If December 22nd and the morning of December 23rd are clear where you are, have a look at the Little Dipper's bowl, and you might see about ten meteors per hour. Watch the full What’s Up for December Video:
