The number of near-Earth asteroids (NEAs) discovered now tops 15,000, with an average of 30 added each week. "While no known NEA currently poses a risk of impact with Earth over the next 100 years," says NASA Planetary Defense Officer Lindley Johnson. "We've found mostly the larger asteroids...we have a lot more of the smaller, but still potentially hazardous ones, to find."

On Oct. 30, 2016, the Solar Dynamics Observatory, or SDO, experienced a partial solar eclipse in space when it caught the moon passing in front of the sun. The lunar transit lasted an hour, with the moon covering about 59 percent of the sun at the peak of its journey across the face of the sun. The moon's shadow occasionally obstructs SDO's otherwise constant view of the sun. The shadow's edge is sharp and distinct, since the moon has no atmosphere that would distort sunlight.

It’s also important to know the Federal Supply Class or Service Codes (FSC/SVC) for your products or services. Prepare a capability brief in both printed and electronic versions with an emphasis on Government work.
In order to register your business with us, there are three systems you’ll need to use. The Data Universal Numbering System (DUNS), the System for Award Management (SAM) and the NASA Vendor Data Base (NVDB). After you’ve survived all those acronyms, your business is registered!
Here at NASA we have centers around the country that each procure different types of business. Where does your product or service fit in? The best thing to do is visit THIS site and find out more about each center. You can also take a look at our Acquisition Forecast to find out about expected contract opportunities.
You can find current procurement opportunities in your product or service area by checking the Federal Business Opportunities website. This site also helps you identify our requirements and even send you e-mail notifications of released requirements.
Contracting procedures can be tedious, it’s always a good idea to familiarize yourself with the Federal Acquisition Regulations (FAR), as well as our supplement to those regulations. Which can be found HERE.
Did you know that many of our purchases are orders on the Federal Supply Schedule contracts? They are, which means you can contact the U.S. General Services Administration (GSA) for information on how to obtain a contract.
There are some very beneficial resources available to you throughout this process. You can request training and counseling on marketing, financial and contracting issues at minimal or no cost from Procurement Technical Assistance Centers (PTACs).
You also have the option to consult with the SBA’s Procurement Center Representatives (PCRs) and the SBA Business Development Centers. The SBA provides each of our centers with a liaison.
There is also an option to get free and confidential mentoring by former CEOs through SCORE.
Direct contracting is not the only route for small businesses. Consider subcontracting opportunities, and get information through the SBA’s SUB-Net or Subcontracting Opportunities Directory. Solicitations or notices are posted by prime contractors. Our list of prime vendors is located on our Marshall Space Flight Center’s website.
Explore other small business programs, such as our Mentor-Protégé Program, the Small Business Innovation Research Program and the Historically Black Colleges and Universities and Minority-Serving Institutions Program. Information on these and other programs is available on our Office of Small Business Programs website.
After you have identified your customers, researched their requirements and familiarized yourself with our procurement regulations and strategies, it’s time to market your product or service.

Just days from now, on Aug. 21, 2017, the Moon will pass between the Sun and Earth, casting its shadow down on Earth and giving all of North America the chance to see a solar eclipse. Remember that it is never safe to look at the partially eclipsed or uneclipsed Sun, so make sure you use a solar filter or indirect viewing method if you plan to watch the eclipse.
Eclipses set the stage for historic science. Past eclipses enabled scientists to study the Sun’s structure, find the first proof of Einstein’s theory of general relativity, and discover the element helium — 30 years before it was found on Earth..
We’re taking advantage of the Aug. 21 eclipse by funding 11 ground-based scientific studies. As our scientists prepare their experiments for next week, we’re looking back to an historic 1860 total solar eclipse, which many think gave humanity our first glimpse of solar storms — called coronal mass ejections — 100 years before scientists first understood what they were.
Coronal mass ejections, or CMEs, are massive eruptions made up of hot gas, plasma and magnetic fields. Bursting from the Sun’s surface, these giant clouds of solar material speed into space up to a million miles per hour and carry enough energy to power the world for 10,000 years if we could harness it. Sometimes, when they’re directed towards Earth, CMEs can affect Earth’s space environment, creating space weather: including triggering auroras, affecting satellites, and – in extreme cases – even straining power grids.
Scientists observed these eruptions in the 1970s during the beginning of the modern satellite era, when satellites in space were able to capture thousands of images of solar activity that had never been seen before.
But in hindsight, scientists realized their satellite images might not be the first record of these solar storms. Hand-drawn records of an 1860 total solar eclipse bore surprising resemblance to these groundbreaking satellite images.
On July 18, 1860, the Moon’s shadow swept across North America, Spain and North Africa. Because it passed over so much populated land, this eclipse was particularly well-observed, resulting in a wealth of scientific observations.
Drawings from across the path of the 1860 eclipse show large, white finger-like projections in the Sun’s atmosphere—called the corona—as well as a distinctive, bubble-shaped structure. But the observations weren’t uniform – only about two-thirds of the 1860 eclipse sketches showed this bubble, setting off heated debate about what this feature could have been.
Sketches from the total solar eclipse of July 1860.
One hundred years later, with the onset of space-based satellite imagery, scientists got another piece of the puzzle. Those illustrations from the 1860 eclipse looked very similar to satellite imagery showing CMEs – meaning 1860 may have been humanity’s first glimpse at these solar storms, even though we didn’t understand what we were seeing.
While satellites provide most of the data for CME research, total solar eclipses seen from the ground still play an important role in understanding our star. During an eclipse, observers on the ground are treated to unique views of the innermost corona, the region of the solar atmosphere that triggers CMEs.
This region of the Sun’s atmosphere can’t be measured at any other time, since human-made instruments that create artificial eclipses must block out much of the Sun’s atmosphere—as well as its bright face—in order to produce clear images. Yet scientists think this important region is responsible for accelerating CMEs, as well as heating the entire corona to extraordinarily high temperatures.
When the path of an eclipse falls on land, scientists take advantage of these rare chances to collect unique data. With each new total solar eclipse, there’s the possibility of new information and research—and maybe, the chance to reveal something as astronomical as the first solar storm.
Learn all about the Aug. 21 eclipse at eclipse2017.nasa.gov, and follow @NASASun on Twitter and NASA Sun Science on Facebook for more. Watch the eclipse through the eyes of NASA at nasa.gov/eclipselive starting at 12 PM ET on Aug. 21.

The radiant of the Quadrantids lies in the demoted constellation Quadrans Muralis.
The Mural Quadrant is an angle measuring device mounted on or built into a wall. Quadrans Muralis appears on some 19th-century star atlases between Hercules, Boötes and Draco, and different astronomers changed the stars from time to time.
In the early 1920's, the International Astronomical Union divided up the sky into official constellations for consistency in star naming. 88 constellations remained, but over 30 historical constellations, including Quadrans Muralis, didn't make the cut.
Most of the Quadrans Muralis stars are now within the boundaries of the official constellation Boötes, but the name of the meteor shower did not change.
Meteor showers are usually the residue that collects in the orbits of comets. Unlike most meteor showers' parent bodies, the Quadrantids are associated with an asteroid—2003 EH1.

Just as gravity is one key to how things move on Earth, a process called magnetic reconnection is key to how electrically-charged particles speed through space. Now, our Magnetospheric Multiscale mission, or MMS, has discovered magnetic reconnection – a process by which magnetic field lines explosively reconfigure – occurring in a new and surprising way near Earth.
Invisible to the eye, a vast network of magnetic energy and particles surround our planet — a dynamic system that influences our satellites and technology. The more we understand the way those particles move, the more we can protect our spacecraft and astronauts both near Earth and as we explore deeper into the solar system.
Earth’s magnetic field creates a protective bubble that shields us from highly energetic particles that stream in both from the Sun and interstellar space. As this solar wind bathes our planet, Earth’s magnetic field lines get stretched. Like elastic bands, they eventually release energy by snapping and flinging particles in their path to supersonic speeds.
That burst of energy is generated by magnetic reconnection. It’s pervasive throughout the universe — it happens on the Sun, in the space near Earth and even near black holes.
Scientists have observed this phenomenon many times in Earth’s vast magnetic environment, the magnetosphere. Now, a new study of data from our MMS mission caught the process occurring in a new and unexpected region of near-Earth space. For the first time, magnetic reconnection was seen in the magnetosheath — the boundary between our magnetosphere and the solar wind that flows throughout the solar system and one of the most turbulent regions in near-Earth space.
The four identical MMS spacecraft — flying through this region in a tight pyramid formation — saw the event in 3D. The arrows in the data visualization below show the hundreds of observations MMS took to measure the changes in particle motion and the magnetic field.
The data show that this event is unlike the magnetic reconnection we’ve observed before. If we think of these magnetic field lines as elastic bands, the ones in this region are much smaller and stretchier than elsewhere in near-Earth space — meaning that this process accelerates particles 40 times faster than typical magnetic reconnection near Earth. In short, MMS spotted a completely new magnetic process that is much faster than what we’ve seen before.
What’s more, this observation holds clues to what’s happening at smaller spatial scales, where turbulence takes over the process of mixing and accelerating particles. Turbulence in space moves in random ways and creates vortices, much like when you mix milk into coffee. The process by which turbulence energizes particles in space is still a big area of research, and linking this new discovery to turbulence research may give insights into how magnetic energy powers particle jets in space.

Our Transiting Exoplanet Survey Satellite (TESS), launched last year on April 18, is completing a year in space, surveying the skies to find the closest, most exciting planets outside our solar system for further study. Worlds that TESS is hunting for include super-Earths, rocky planets, gas giants, and maybe even some Earth-sized planets — and much, much more! TESS is scanning the whole sky one section at a time, monitoring the brightness of stars for periodic dips caused by planets transiting (that is, passing in front of) those stars. So far, TESS has found 548 candidates and 10 confirmed exoplanets.
Since its launch, TESS has orbited Earth a total of 28 times. TESS has a unique elliptical orbit that circuits around Earth twice every time the Moon orbits. This allows TESS’s cameras to monitor each patch of sky continuously for nearly a month at a time. To get into this special orbit, TESS made a series of loops culminating in a lunar gravitational assist, which gave it the final push it needed.
Did you know that TESS has some serious mileage? The spacecraft has traveled about 20 million miles so far, which works out to an average of about 2,200 miles per hour. That’s faster than any roadrunner we’ve ever seen! This would be four times faster than an average jet. You’d get to your destination in no time!
TESS downloads data during its closest approach to Earth about every two weeks. So far, it has returned 12,000 gigabytes of data. That’s as if you streamed about 3,000 movies on Netflix. Get the popcorn ready! If you total all the pixels from every image taken using all four of the TESS cameras — which is about 600 full-frame images per orbit, you’d get about 805 billion pixels. This is like half a million iPhone screens put together!
When the Kepler Space Telescope reached the end of its mission, it passed the planet-finding torch to TESS. Where Kepler's view was deep — looking for planets as far away as 3,000 light-years — TESS's view is wide, surveying nearly the entire sky over two years. Each sector TESS views is 20 times larger than Kepler's field of view.
TESS will continue to survey the sky and is expected to find about 20,000 exoplanets in the two years it'll take to complete a scan of nearly the entire sky. Before TESS, several thousand candidate exoplanets were found, and more than 3,000 of these were confirmed. Some of these exoplanets are expected to range from small, rocky worlds to giant planets, showcasing the diversity of planets in the galaxy.
The TESS mission is led by MIT and came together with the help of many different partners. You can keep up with the latest from the TESS mission by following mission updates and keep track of the number of candidates and confirmed exoplanets.

NOAA’s GOES-R weather satellite will soon be launched into space – becoming our nation’s most advanced geostationary satellite to date. So what does that mean for you? Here are six reasons to be excited about GOES-R:
Perhaps you turn on the TV or radio, or check your favorite weather website or smartphone weather app to get the latest forecast. No matter the platform of your weather forecast, the data and information for those forecasts come from NOAA’s National Weather Service (NWS).
Weather satellites, like the GOES satellites, are the backbone of NWS forecasts. GOES-R will be more advanced than any other weather satellite of its kind and could make the answer to the question “What’s the weather going to be?” more detailed and accurate both in the near term and further out into the future.
Do you live in an inland state, a state with a coastline or a state with a mountain range? Great, that’s all of you! Data from the GOES-R satellite will be a game changer for forecasters in your area.
Here’s why: satellites are fitted with instruments that observe weather and collect measurements. The primary instrument on the new GOES-R satellite will collect three times more data and provide four times better resolution and more than five times faster coverage than current satellites! This means the satellite can scan Earth’s Western Hemisphere every five minutes and as often as every 30 seconds in areas where severe weather forms, as compared to approximately every 30 minutes with the current GOES satellites. Pretty cool, right?
This expedited data means that forecasts will be timelier, with more “real-time” information in them, allowing NWS to make those warnings and alerts that much faster, thereby potentially saving lives.
And a faster forecast is a big deal for our economy. Commercial shipping and aviation are just two examples of industries that rely on up-to-date weather data for critical decisions about how to route ships and safely divert planes around storms.
We all depend on a power grid for virtually every aspect of modern life. But power grids are vulnerable to bursts of energy from the sun that can affect us on Earth.
Luckily, GOES-R will be sitting over 22,000 miles above us, and in addition to measuring weather on Earth, it will monitor incoming space weather.
How different will GOES-R be? Imagine going from your classic black and white TV to a new high definition one. It will enable NOAA to gather data using three times more channels, four times the resolution, five times faster than the current GOES satellites.
This faster, more accurate data means better observations of developing storms and other severe weather.
6. GOES-R will be a continuing a legacy
GOES-R may be the first of its kind, but it is the heir to a rich tradition of geostationary earth observation.
In fact, NOAA has continuously operated a GOES satellite for over 40 years. Since 1975, GOES satellites have taken well over 3 million images!
The GOES-R satellite is scheduled to launch Saturday, Nov. 19 at 5:42 p.m. EST aboard a United Launch Alliance Atlas V rocket. Liftoff will occur from our Kennedy Space Center in Florida.
