KENNEDY SPACE CENTER, FL – A SpaceX Dragon supply ship jam packed with more than 2.5 tons of critical science gear, crew supplies and 40 mice successfully arrived this morning at the International Space Station (ISS) – where six humans from the US, Russia and France are living and working aboard.

Dragon reached the station four days after it was launched from the Kennedy Space Center (KSC) on Sunday, Feb. 19 on the first Falcon 9 rocket ever to blast off from historic launch pad 39A in a blaze of glory.

Astronauts Thomas Pesquet of ESA (European Space Agency) and station commander Shane Kimbrough of NASA deftly maneuvered the space station’s 57.7-foot (17.6-meter) Canadian-built Canadarm2 robotic arm to reach out and flawlessly capture the Dragon CRS-10 spacecraft at about 5:44 a.m. EST early Thursday, after it arrived at the station.

Pesquet and Kimbrough were working at the robotics work station inside the seven windowed Cupola module as they monitored Dragon’s approach for capture by the grappling snares on the terminus of the robotic arm this morning as the station was soaring over the northwest coast of Australia.

“Looks like we have a great Dragon capture,” said capcom astronaut Mike Hopkins.

“We want to congratulate all the teams working around the world for the successful arrival,” said Pesquet.

The million pound station is orbiting approximately 250 miles (400 km) above Earth.

The commercial Dragon cargo freighter arrived about 16 minutes earlier than originally planned.

The duo were assisted by experienced NASA astronaut Peggy Whitson. The 57 year old Whitson will soon set a record for most time spent in space by an American on April 24.

The gumdrop shaped Dragon cargo freighter slowly and methodically approached the station and the capture point through the required approach corridor during the final stages of the orbital chase.

After hovering at the capture point in free drift at a distance of about 34 feet (11 m) from the orbiting outpost, the crew members extended the robotic arm and Dragon was successfully plucked from free space using Canardarm2 at the grapple fixture located on the side of the supply ship.

The entire thrilling approach and grappling sequence was broadcast live on NASA TV.

Robotics officers on the ground at the NASA’s Johnson Space Center then took over and berthed Dragon to the Earth facing port on the Harmony module at about 8 a.m. as the mated craft were soaring over central America.

16 latches and bolts on the stations Common Berthing Mechanism (CBM) will hold Dragon firmly in place for a hard mate to the stations Harmony module.

4 gangs of 4 bolts were driven into place with ground commands from the robotics officer to firmly bolt Dragon to the nadir port on Harmony.

The second stage capture and Dragon installation was confrmed at 8:12 a.m. Feb 23 as the craft were flying over the US East Coast.

“Today’s’ re-rendezvous has gone by the book,” said NASA commentator Rob Navias.

“Dragon systems are in excellent shape.”

“There have been no issues and everything has gone as planned.”

“Today was smooth sailing as Dragon arrived below the space station and maneuvered its way through a carefully choreographed procedure to the grapple position for rendezvous and capture.”

“Dragon is now firmly attached to the International Space Station and the crew will begin unloading critical science payloads and supplies this afternoon.”

“Today’s’ re-rendezvous has gone by the book,” said NASA commentator Rob Navias.

“Dragon systems are in excellent shape.”

“There have been no issues and everything has gone as planned.”

Yesterday’s rendezvous was automatically aborted when a bad bit of navigational data was uplinked to Dragons relative GPS navigation system as it was about 0.7 miles below the station.

“The Dragon’s computers received an incorrect navigational update, triggering an automatic wave off. Dragon was sent on a “racetrack” trajectory in front of, above and behind the station for today’s second rendezvous attempt.”

There was never any danger to the crew, space station or Dragon. It merely arrived a day later than planned as it is fully equipped to do if needed.

CRS-10 counts as the company’s tenth scheduled flight to deliver supplies, science experiments and technology demonstrations to the International Space Station (ISS).

The Dragon is the first of two cargo craft arriving at the station over two consecutive days.

The unpiloted Russian Progress 66 supply ship launched yesterday from Baikonur is slated to arrive early Friday morning with 2.9 tons of supplies. It will automatically dock at the Pirs docking module at about 3:45 a.m., with a trio of Russian cosmonauts monitoring all the action.

After conducting leak checks, the crew plans to open the hatch to Dragon later today.

They will quickly begin removing the highest priority science investigations and gear first.

Dragon will remain at the station for about 30 days.

1000 pounds of ‘late stow’ experiments were loaded the day before the originally planned Feb. 18 liftoff of the SpaceX Falcon 9 rocket.

Dragon was successfully launched from NASA’s Kennedy Space Center atop the 213-foot-tall (65-meter) SpaceX Falcon 9 rocket at 9:38 a.m. EST on Feb. 19, 2017 from historic Launch Complex 39A to low Earth orbit.

Dragon is carrying more than 5500 pounds of equipment, gear, food, crew supplies, hardware and NASA’s Stratospheric Aerosol Gas Experiment III (SAGE III) ozone mapping science payload in support of the Expedition 50 and 51 crew members.

SAGE III will measure stratospheric ozone, aerosols, and other trace gases by locking onto the sun or moon and scanning a thin profile of the atmosphere. It is one of NASA’s longest running earth science programs.

The LIS lightning mapper will measure the amount, rate and energy of lightning as it strikes around the world from the altitude of the ISS as it orbits Earth. Its data will complement that from the recently orbited GLM lighting mapper lofted to geosynchronous aboard the NASA/NOAA GOES-R spacecraft instrument.

NASA’s RAVEN experiment will test autonomous docking technologies for spacecraft.

SAGE III and RAVEN were stowed in the Dragon’s unpressurized truck.

The research supplies and equipment brought up by Dragon will support over 250 scientific investigations to advance knowledge about the medical, psychological and biomedical challenges astronauts face during long-duration spaceflight.

The 40 mice will be used in a wound healing experiment to test therapies in microgravity.

An advanced plant growth habitat will launch soon to test better technologies for growing crops in space that could contribute to astronauts nutrition on long duration spaceflights.

Get Ready for the First Pictures of a Black Hole’s Event Horizon

It might sound trite to say that the Universe is full of mysteries. But it’s true.

Chief among them are things like Dark Matter, Dark Energy, and of course, our old friends the Black Holes. Black Holes may be the most interesting of them all, and the effort to understand them—and observe them—is ongoing.

That effort will be ramped up in April, when the Event Horizon Telescope (EHT) attempts to capture our first image of a Black Hole and its event horizon. The target of the EHT is none other than Sagittarius A, the monster black hole that lies in the center of our Milky Way Galaxy. Though the EHT will spend 10 days gathering the data, the actual image won’t be finished processing and available until 2018.

The EHT is not a single telescope, but a number of radio telescopes around the world all linked together. The EHT includes super-stars of the astronomy world like the Atacama Large Millimeter Array (ALMA) as well as lesser known ‘scopes like the South Pole Telescope (SPT.) Advances in very-long-baseline-interferometry (VLBI) have made it possible to connect all these telescopes together so that they act like one big ‘scope the size of Earth.

The ALMA array in Chile. Once ALMA was added to the Event Horizon Telescope, it increased the EHT’s power by a factor of 10. Image: ALMA (ESO/NAOJ/NRAO), O. Dessibourg

The combined power of all these telescopes is essential because even though the EHT’s target, Sagittarius A, has over 4 million times the mass of our Sun, it’s 26,000 light years away from Earth. It’s also only about 20 million km across. Huge but tiny.

The EHT is impressive for a number of reasons. In order to function, each of the component telescopes is calibrated with an atomic clock. These clocks keep time to an accuracy of about a trillionth of a second per second. The effort requires an army of hard drives, all of which will be transported via jet-liner to the Haystack Observatory at MIT for processing. That processing requires what’s called a grid computer, which is a sort of virtual super-computer comprised of 800 CPUs.

But once the EHT has done its thing, what will we see? What we might see when we finally get this image is based on the work of three big names in physics: Einstein, Schwarzschild, and Hawking.

A simulation of what the EHT might show us. Image: Event Horizon Telescope Organization

As gas and dust approach the black hole, they speed up. They don’t just speed up a little, they speed up a lot, and that makes them emit energy, which we can see. That would be the crescent of light in the image above. The black blob would be a shadow cast over the light by the hole itself.

Einstein didn’t exactly predict the existence of Black Holes, but his theory of general relativity did. It was the work of one of his contemporaries, Karl Schwarzschild, that actually nailed down how a black hole might work. Fast forward to the 1970s and the work of Stephen Hawking, who predicted what’s known as Hawking Radiation.

Taken together, the three give us an idea of what we might see when the EHT finally captures and processes its data.

Einstein’s general relativity predicted that super massive stars would warp space-time enough that not even light could escape them. Schwarzschild’s work was based on Einstein’s equations and revealed that black holes will have event horizons. No light emitted from inside the event horizon can reach an outside observer. And Hawking Radiation is the theorized black body radiation that is predicted to be released by black holes.

The power of the EHT will help us clarify our understanding of black holes enormously. If we see what we think we’ll see, it confirms Einstein’s Theory of General Relativity, a theory which has been confirmed observationally over and over. If EHT sees something else, something we didn’t expect at all, then that means Einstein’s General Relativity got it wrong. Not only that, but it means we don’t really understand gravity.

In physics circles they say that it’s never smart to bet against Einstein. He’s been proven right time and time again. To find out if he was right again, we’ll have to wait until 2018.

NASA’s Historic Pad 39A Back in Business with Maiden SpaceX Falcon 9 Blastoff to ISS and Booster Landing

KENNEDY SPACE CENTER, FL – After a six year lull NASA’s historic pad 39A roared back to business this morning with the dramatic maiden blastoff of a SpaceX Falcon 9 rocket, on a critical cargo delivery mission for NASA to the space station – while simultaneously landing the first stage back on the ground at the Cape on a secondary mission aimed at one day propelling humans to Mars.

The era of undesired idleness for America’s most famous launch pad was broken at last by the rumbling thunder of a SpaceX Falcon 9 that ignited at 9:38 a.m. EST Sunday morning, Feb 19, at Launch Complex 39A at NASA’s Kennedy Space Center.

The storied liftoff took place under heavily overcast skies with rain showers nearby under seemingly improbable weather conditions.

After liftoff, the rocket disappeared within seconds and never really reappeared in the local area until the final moments of the descent of the first stage – which nailed a nearly perfect dead center touchdown at Landing Zone 1 at the Cape some 9 minutes after launch.

Nevertheless the Falcon 9 launch was a smashing success and probably the loudest I have ever witnessed since the shuttle era ended. Watching from atop the roof of the iconic VAB, I can report the building did experience some rather exciting rattling!

And it was SpaceX’s first daylight booster landing back at the Cape. The two earleir touchdowns were at night – most recently for the CRS-9 mission last summer in July 2016.

The goal of the mission was aimed at launching the SpaceX Dragon cargo freighter to deliver over 5500 pounds of science and supplies to the orbiting science outpost on the CRS-10 mission.

The Dragon spacecraft was successfully delivered in Earth orbit and is on course for the International Space Station (ISS) on the CRS-10 mission.

As a secondary side goal, SpaceX successfully carried out a propulsive soft landing of the 156 foot tall first stage of the Falcon 9 rocket on land at Cape Canaveral Air Force Station’s Landing Zone 1 (LZ-1), located about 9 miles south of KSC launch complex 39A.

The touchdown, like the launch was completely obscured until the final moments of the descent, when it suddenly and magnificently reappeared as a strange pale colored cylinder emitting a long yellow flame after dropping below the low hanging clouds.

The booster successfully accomplished a propulsive upright soft landing at Landing Zone-1 (LZ-1) accompanied by multiple sonic booms at Cape Canaveral Air Force Station, Florida, about 9 minutes after launch.

This was the 8th first stage booster that SpaceX has successfully recovered either by land or on a tiny droneship at sea over the past year.

The goal is to refurbish and recycle the 156 foot tall first stage boosters for relaunch with a new payload.

SpaceX CEO billionaire Elon Musk hopes that by reusing the spent booster, he can drastically cut the cost of access to space and that will one day lead to human colonies and a “City on Mars.”

The dream of Bob Cabana, former astronaut and now Center Director at the Kennedy Space Center NASA’s, to turn KSC into a multiuser spaceport open to utilization by government, industry and entrepreneurs like SpaceX’s billionaire CEO Elon Musk is finally coming to fruition in a blaze of glory.

“I’m so proud of this team for all the dedication and hard work,” said Cabana.

Today’s launch counts as the first commercial launch from Kennedy’s historic pad.

The storied pad initially sent NASA astronauts to the Moon soon after the dawn of the Space Age during the Apollo/Saturn era and was then significantly overhauled to serve as the on ramp for NASA space shuttles for another three decades.

SpaceX has now transformed pad 39A for launches of the Falcon 9. A bright future lies ahead with launches of the heavy lift Falcon Heavy later this year and a renewal of manned launches of astronauts some time in 2018.

SAGE III will measure stratospheric ozone, aerosols, and other trace gases by locking onto the sun or moon and scanning a thin profile of the atmosphere.

The LIS lightning mapper will measure lightning from the altitude of the ISS. NASA’s RAVEN experiment will test autonomous docking technologies for spacecraft.

As of today we are at last launching rockets again from the Kennedy Space Center – thanks to SpaceX and the Falcon 9. What a tremendous return to space !

The Universe Has A Lithium Problem

This illustration shows the evolution of the Universe, from the Big Bang on the left, to modern times on the right. Image: NASA

Over the past decades, scientists have wrestled with a problem involving the Big Bang Theory. The Big Bang Theory suggests that there should be three times as much lithium as we can observe. Why is there such a discrepancy between prediction and observation?

To get into that problem, let’s back up a bit.

The Big Bang Theory (BBT) is well-supported by multiple lines of evidence and theory. It’s widely accepted as the explanation for how the Universe started. Three key pieces of evidence support the BBT:

observations of the Cosmic Microwave Background
our growing understanding of the large-scale structure of the Universe
rough agreement between calculations and observations of the abundance of primordial light nuclei (Do NOT attempt to say this three times in rapid succession!)

But the BBT still has some niggling questions.

The missing lithium problem is centred around the earliest stages of the Universe: from about 10 seconds to 20 minutes after the Big Bang. The Universe was super hot and it was expanding rapidly. This was the beginning of what’s called the Photon Epoch.

At that time, atomic nuclei formed through nucleosynthesis. But the extreme heat that dominated the Universe prevented the nuclei from combining with electrons to form atoms. The Universe was a plasma of nuclei, electrons, and photons.

Only the lightest nuclei were formed during this time, including most of the helium in the Universe, and small amounts of other light nuclides, like deuterium and our friend lithium. For the most part, heavier elements weren’t formed until stars appeared, and took on the role of nucleosynthesis.

The problem is that our understanding of the Big Bang tells us that there should be three times as much lithium as there is. The BBT gets it right when it comes to other primordial nuclei. Our observations of primordial helium and deuterium match the BBT’s predictions. So far, scientists haven’t been able to resolve this inconsistency.

But a new paper from researchers in China may have solved the puzzle.

One assumption in Big Bang nucleosynthesis is that all of the nuclei are in thermodynamic equilibrium, and that their velocities conform to what’s called the classical Maxwell-Boltzmann distribution. But the Maxwell-Boltzmann describes what happens in what is called an ideal gas. Real gases can behave differently, and this is what the researchers propose: that nuclei in the plasma of the early photon period of the Universe behaved slightly differently than thought.

This graphics shows the distribution of early primordial light elements in the Universe by time and temperature. Temperature along the top, time along the bottom, and abundance on the side. Image: Hou et al. 2017

The authors applied what is known as non-extensive statistics to solve the problem. In the graph above, the dotted lines of the author’s model predict a lower abundance of the beryllium isotope. This is key, since beryllium decays into lithium. Also key is that the resulting amount of lithium, and of the other lighter nuclei, now all conform to the amounts predicted by the Maxwell-Boltzmann distribution. It’s a eureka moment for cosmology aficionados.

The decay chains of primordial light nuclei in the early days of the Universe. Notice the thin red arrows between Beryllium and Lithium at 10-13, the earliest time shown on this chart. Image: Chou et. al.

What this all means is scientists can now accurately predict the abundance in the primordial universe of the three primordial nuclei: helium, deuterium, and lithium. Without any discrepancy, and without any missing lithium.

This is how science grinds away at problems, and if the authors of the paper are correct, then it further validates the Big Bang Theory, and brings us one step closer to understanding how our Universe was formed.

Eureka!

At T Minus 1 Day from ISS Liftoff SpaceX Rolls Falcon 9 to KSC Pad 39A – Feb. 18 Ignition Hinges on FAA License Approval

KENNEDY SPACE CENTER, FL – Its getting down to the wire at T Minus 1 Day from liftoff for SpaceX and NASA as a Falcon 9 rocket was rolled out to historic Launch Complex 39A today, Feb 16, and the Feb. 18 ignition to the space station hinges on the approval of a launch license yet to be granted, the Federal Aviation Administration (FAA) confirmed late today to Universe Today.

“My previous background still applies,” FAA spokesman Hank Price confirmed to Universe Today.

“The FAA is working closely with SpaceX to ensure the activity described in the application meets all applicable regulations for a launch license.”

“The FAA will continue to work with SpaceX to provide a license determination in a timely manner.”

Blastoff of the Falcon 9 from seaside pad 39A at NASA’s Kennedy Space Center in Florida is slated for 10:01 a.m. EST Saturday, Feb. 18.

NASA plans live coverage of the launch beginning at 8:30 a.m. on NASA Television and the agency’s website.

SpaceX currently has license applications pending with the FAA for both the NASA cargo launch and pad 39A. No commercial launch can take place without FAA approval.

No License, No Launch – that’s the bottom line!

Assuming the FAA grants a launch license at the last minute on Friday the weather outlook currently is iffy for Saturday with a 60% chance of favorable conditions at launch time. The concerns are for rains and clouds according to Air Force weather forecasters.

In case of a scrub for any reason on Feb. 18, the backup launch opportunity is 9:38 a.m. Sunday, Feb. 19.

Technically all appears to be on track for the historic first launch of a Falcon 9 from pad 39A pending further reviews and updates from NASA and SpaceX on Friday.

After a successful static fire test of the two stage rocket and all nine first stage Merlin 1D engines on Sunday afternoon, Feb. 12, the path to orbit was cleared for a critical Dragon cargo flight for NASA to deliver over two and a half tons of science and supplies on the CRS-10 resupply mission to the six person crew living and working on the International Space Station (ISS).

The SpaceX Falcon 9 rocket was then integrated with the unmanned Dragon CRS-10 cargo freighter was rolled out of the SpaceX processing hangar at the perimeter fence and then up the incline to the top of pad 39A this morning using a dedicated transporter-erector, so crew could begin final preparation for the Saturday morning blastoff.

From atop KSC pad 39B I witnessed the rocket residing horizontally atop pad 39A as technicians further moved the rocket to launch position.

The 22 story tall Falcon 9/Dragon vehicle was erected to vertical launch position later this afternoon at about 4:50 p.m. to conduct additional ground checks and testing.

It will again be lowered to the horizontal position, so that late load cargo items can be stowed inside the Dragon spaceship on Friday before raising the rocket again into the final launch configuration.

This marks the first time any fully integrated rocket has stood on pad 39A for a scheduled launch since the retirement of NASA’s Space Shuttles in July 2011 on the STS-135 mission to the space station.

The historic NASA launch pad was formerly used to launch both America’s space shuttles and astronauts on Apollo/Saturn V moon landing missions as far back as the 1960s.

SAGE III will measure stratospheric ozone, aerosols, and other trace gases by locking onto the sun or moon and scanning a thin profile of the atmosphere.

The LIS lightning mapper will measure lightning from the altitude of the ISS. NASA’s RAVEN experiment will test autonomous docking technologies for spacecraft.

About 10 minutes after launch, Dragon will reach its preliminary orbit, deploy its solar arrays and begin a carefully choreographed series of thruster firings to reach the space station.

As a secondary objective SpaceX s planning to attempt to land its Falcon 9 first stage on land at Landing Zone 1 at Cape Canaveral Air Force Station.

‘Astronauts Shane Kimbrough of NASA and Thomas Pesquet of ESA (European Space Agency) will use the station’s robotic arm to capture Dragon when it arrives at the space station after its two-day journey. The spacecraft will be berthed to the Earth-facing port on the Harmony module. The following day, the space station crew will pressurize the vestibule between the station and Dragon, then open the hatch that leads to the forward bulkhead of Dragon,’ according to NASA.

Pad 39A has lain dormant for launches for nearly six years since Space Shuttle Atlantis launched on the final shuttle mission STS 135 in July 2011.

See a Flirtatious Lunar Eclipse This Friday Night

This sequence of photos taken on October 18, 2013 nicely show the different phases of a penumbral lunar eclipse. The coming penumbral eclipse will likely appear even darker because Earth’s shadow will shade to the top (northern) half of the Moon rich in dark lunar “seas” at maximum. Credit: **AstroTripper 2000**

Not many people get excited about a penumbral eclipse, but when it’s a deep one and the only lunar eclipse visible in North America this year, it’s worth a closer look. What’s more, this Friday’s eclipse happens during convenient, early-evening viewing hours. No getting up in the raw hours before dawn.

Lunar eclipses — penumbral, partial and total — always occur at Full Moon, when the Moon, Earth and Sun line up squarely in a row in that order. Only then does the Moon pass through the shadow cast by our planet. Credit: Starry Night with additions by the author

During a partial or total lunar eclipse, the full moon passes first through the Earth’s outer shadow, called the penumbra, before entering the dark, interior shadow or umbra. The penumbra is nowhere near as dark as the inner shadow because varying amounts of direct sunlight filter into it, diluting its duskiness.

To better understand this, picture yourself watching the eclipse from the center of the Moon’s disk (latitude 0°, longitude 0°). As you look past the Earth toward the Sun, you would see the Sun gradually covered or eclipsed by the Earth. Less sunlight would be available to illuminate the Moon, so your friends back on Earth would notice a gradual dimming of the Moon, very subtle at first but becoming more noticeable as the eclipse progressed.

This diagram shows an approximation of the Sun’s position and size as viewed by an observer at the center of the lunar disk during Friday’s penumbral eclipse. More sunlight shines across the Moon early in the eclipse, making the penumbral shadow very pale, but by maximum (right), half the sun is covered and the Moon appears darker and duskier as seen from Earth.

As the Moon’s leading edge approached the penumbra-umbra border, the Sun would narrow to a glaring sliver along Earth’s limb for our lucky lunar observer. Back on Earth, we’d notice that the part of the Moon closest to the umbra looked strangely gray and dusky, but the entire lunar disk would still be plainly visible. That’s what we’ll see during Friday’s eclipse. The Moon will slide right up to the umbra and then roll by, never dipping its toes in its dark waters.

During a partial eclipse, the Moon keeps going into the umbra, where the Sun is completely blocked from view save for dash of red light refracted by the Earth’s atmosphere into what would otherwise be an inky black shadow. This eclipse, the Moon only flirts with the umbra.

The moon’s orbit is tilted 5.1 degrees in relation to Earth’s orbit, so most Full Moons, it passes above or below the shadow and no eclipse occurs. Credit: Bob King

Because the moon’s orbit is tilted about 5° from the plane of Earth’s orbit, it rarely lines up for a perfect bullseye total eclipse: Sun – Earth – Moon in a straight line in that order. Instead, the moon typically passes a little above or below (north or south) of the small, circle-shaped shadow cast by our planet, and no eclipse occurs. Or it clips the outer edge of the shadow and we see — you guessed it — a penumbral eclipse.

Earth’s shadow varies in size depending where you are in it. Standing on the ground during twilight, it can grow to cover the entire sky, but at the moon’s distance of 239,000 miles, the combined penumbra and umbra span just 2.5° of sky or about the width of your thumb held at arm’s length.

The moon passes through Earth’s outer shadow, the penumbra, on Feb. 10-11. In the umbra, the sun is blocked from view, but the outer shadow isn’t as dark because varying amounts of sunlight filter in to dilute the darkness. Times are Central Standard. Credit: F. Espenak, NASA’s GFSC with additions by the author

Because the Moon travels right up to the umbra during Friday’s eclipse, it will be well worth watching.The lower left or eastern half of the moon will appear obviously gray and blunted especially around maximum eclipse as it rises in the eastern sky that Friday evening over North and South America. I should mention here that the event is also visible from Europe, Africa, S. America and much of Asia.

This map shows where the eclipse will be visible. Most of the U.S. will see at least part of the event. Credit: F. Espenak, NASA’s GFSC

For the U.S., the eastern half of the country gets the best views. Here are CST and UT times for the different stages. To convert from CST, add an hour for Eastern, subtract one hour for Mountain and two hours for Pacific times. UT stands for Universal Time, which is essentially the same as Greenwich or “London” Time except when Daylight Saving Time is in effect:

This is a simulated view of the Full **Snow Moon** at maximum eclipse Friday evening low in the eastern sky alongside the familiar asterism known as the Sickle of Leo. Created with Stellarium

Eclipse begins: 4:34 p.m. (22:34 p.m. UT)
Maximum eclipse (moon deepest in shadow): 6:44 p.m. (00:43 UT Feb. 11)
Eclipse ends: 8:53 p.m. (2:53 UT Feb. 11)

You can see that the eclipse plays out over more than 4 hours, though I don’t expect most of us will either be able or would want to devote that much time. Instead, give it an hour or so when the Moon is maximally in shadow from 6 to 7:30 p.m. CST; 7-8:30 EST; 5-6:30 p.m. MST and around moonrise Pacific time.

This should be a fine and obvious eclipse because around the time of maximum, the darkest part of the penumbra shades the dark, mare-rich northern hemisphere of the Moon. Dark plus dark equals extra dark! Good luck and clear skies!

New Age in Weather Forecasting Begins with Spectacular 1st Images from NASA/NOAA GOES-16 Observatory

KENNEDY SPACE CENTER, FL – A new age has begun in the nations weather forecasting capabilities with the release today (Jan. 23) of the spectacular first images gathered by the recently launched NASA/NOAA GOES-16 observatory.

The highly advanced Geostationary Operational Environmental Satellite-16 (GOES-16) weather observatory lifted off two months ago atop a ULA Atlas V rocket on Nov. 19, 2016 from Space Launch Complex 41 (SLC-41) on Cape Canaveral Air Force Station, Florida.

GOES-16 (formerly known as GOES-R through the launch) is the first in a new series of revolutionary NASA/NOAA geostationary weather satellites that entails the first significant instrument upgrade to US weather forecasting capabilities in more than two decades.

“It will be like high-definition from the heavens,” says NOAA.

“Today’s release of the first images from #GOES16 signals the start of a new age in satellite weather observation!!!”

Thus the newly obtained and published imagery has been anxiously awaited by scientists, meteorologists and ordinary weather enthusiasts.

“This is such an exciting day for NOAA! One of our GOES-16 scientists compared this to seeing a newborn baby’s first pictures — it’s that exciting for us,” said Stephen Volz Ph.D. director of NOAA’s Satellite and Information Service, in a statement.

“These images come from the most sophisticated technology ever flown in space to predict severe weather on Earth. The fantastically rich images provide us with our first glimpse of the impact GOES-16 will have on developing life-saving forecasts.”

This image clearly shows the significant storm system that crossed North America that caused freezing and ice that resulted in dangerous conditions across the United States on January 15, 2017 resulting in loss of life. Credit: NOAA/NASA

An especially eye-popping image taken by GOES -16 from its equatorial vantage point situated in geostationary orbit 22,300 miles (35,800 kilometers) above Earth and published today, shows both the Earth and the Moon together – as the lead image here.

The Earth/Moon combo shot is not only fantastically pleasing to the eye, but also serves a significant scientific purpose.

“Like earlier GOES satellites, GOES-16 will use the moon for calibration,” say NOAA officials.

“GOES-16 will boost the nation’s weather observation network and NOAA’s prediction capabilities, leading to more accurate and timely forecasts, watches and warnings.”

GOES-16 is the most advanced and powerful weather observatory ever built and will bring about a ‘quantum leap’ in weather forecasting.

“Seeing these first images from GOES-16 is a foundational moment for the team of scientists and engineers who worked to bring the satellite to launch and are now poised to explore new weather forecasting possibilities with this data and imagery,” said Volz.

“The incredibly sharp images are everything we hoped for based on our tests before launch. We look forward to exploiting these new images, along with our partners in the meteorology community, to make the most of this fantastic new satellite.”

It’s dramatic new imagery will show the weather in real time enabling critical life and property forecasting, help pinpoint evacuation zones and also save people’s lives in impacted areas of severe weather including hurricanes and tornadoes.

And the huge satellite can’t come online soon enough, as demonstrated by the severe winter weather and tornadoes that just wreaked havoc and death in various regions of the US.

Another breathtaking image product (seen below) produced by the GOES-16 Advanced Baseline Imager (ABI) instrument, built by Harris Corporation, shows a full-disc view of the Western Hemisphere in high detail — at four times the image resolution of existing GOES spacecraft.

This composite color full-disk visible image shows North and South America and was taken on January 15, 2017. It was created using several of the 16 spectral channels available on the GOES-16 Advanced Baseline Imager (ABI) instrument. Credit: NOAA/NASA

The 11,000 pound satellite was built by prime contractor Lockheed Martin and is the first of a quartet of four identical satellites – comprising GOES-R, S, T, and U – at an overall cost of about $11 Billion. This will keep the GOES satellite system operational through 2036.

This next generation of GOES satellites will replace the currently operating GOES East and GOES West satellites.

NOAA will soon decide whether GOES-16 will replace either the East or West satellites. A decision from NOAA is expected in May. GOES-16 will be operational by November 2017 as either the GOES-East or GOES-West satellite. Of course everyone wants it first.

The next satellite is nearing assembly completion and will undergo about a year of rigorous environmental and acoustic testing before launch. It will go to whichever slot was not selected this year.

These channels help forecasters distinguish between differences in the atmosphere like clouds, water vapor, smoke, ice and volcanic ash. Credit: NOAA/NASA

The six instrument science suite includes the Advanced Baseline Imager (ABI) built by Harris Corporation, the Geostationary Lightning Mapper (GLM) built by Lockheed Martin, Solar Ultraviolet Imager (SUVI), Extreme Ultraviolet and X-Ray Irradiance Sensors (EXIS), Space Environment In-Situ Suite (SEISS), and the Magnetometer (MAG).

ABI is the primary instrument and will collect 3 times more spectral data with 4 times greater resolution and scans 5 times faster than ever before – via the primary Advanced Baseline Imager (ABI) instrument – compared to the current GOES satellites.

“The higher resolution will allow forecasters to pinpoint the location of severe weather with greater accuracy. GOES-16 can provide a full image of Earth every 15 minutes and one of the continental U.S. every five minutes, and scans the Earth at five times the speed of NOAA’s current GOES imagers.”

NASA Webb Telescope Structure is Sound After Vibration Testing Detects Anomaly

NASA GODDARD SPACE FLIGHT CENTER, MD – The James Webb Space Telescope (JWST) is now deemed “sound” and apparently unscathed, engineers have concluded, based on results from a new batch of intensive inspections of the observatory’s structure, after concerns were raised in early December when technicians initially detected “anomalous readings” during a preplanned series of vibration tests, NASA announced Dec. 23.

After conducting both “visual and ultrasonic examinations” at NASA’s Goddard Space Flight Center in Maryland, engineers have found it to be safe at this point with “no visible signs of damage.”

But because so much is on the line with NASA’s $8.8 Billion groundbreaking Webb telescope mission that will peer back to nearly the dawn of time, engineers are still investigating the “root cause” of the “vibration anomaly” first detected amidst shake testing on Dec. 3.

“The team is making good progress at identifying the root cause of the vibration anomaly,” NASA explained in a Dec 23 statement – much to everyone’s relief!

“They have successfully conducted two low level vibrations of the telescope.”

“All visual and ultrasonic examinations of the structure continue to show it to be sound.”

Starting late November, technicians began a defined series of environmental tests including vibration and acoustics tests to make sure that the telescopes huge optical structure was fit for blastoff and could safely withstand the powerful shaking encountered during a rocket launch and the especially harsh rigors of the space environment. It would be useless otherwise – unable to carry out unparallelled science.

To carry out the vibration and acoustics tests conducted on equipment located in a shirtsleeve environment, the telescope structure was first carefully placed inside a ‘clean tent’ structure to protect it from dirt and grime and maintain the pristine clean room conditions available inside Goddard’s massive clean room – where it has been undergoing assembly for the past year.

NASA’s James Webb Space Telescope is the most powerful space telescope ever built and is the scientific successor to the phenomenally successful Hubble Space Telescope (HST).

The mammoth 6.5 meter diameter primary mirror has enough light gathering capability to scan back over 13.5 billion years and see the formation of the first stars and galaxies in the early universe.

The Webb telescope will launch on an ESA Ariane V booster from the Guiana Space Center in Kourou, French Guiana in 2018.

“The James Webb Space Telescope is undergoing testing to make sure the spacecraft withstands the harsh conditions of launch, and to find and remedy all possible concerns before it is launched from French Guiana in 2018.”

However, shortly after the vibration testing began technicians soon discovered unexpected “anomalous readings” during a shake test of the telescope on Dec. 3, as the agency initially announced in a status update on the JWST website.

The anomalous readings were found during one of the vibration tests in progress on the shaker table, via accelerometers attached to the observatories optical structure known as OTIS.

“During the vibration testing on December 3, at Goddard Space Flight Center in Greenbelt, Maryland, accelerometers attached to the telescope detected anomalous readings during a particular test,” the team elaborated.

So the team quickly conducted further “low level vibration” tests and inspections to more fully understand the nature of the anomaly, as well as scrutinize the accelerometer data for clues.

“Further tests to identify the source of the anomaly are underway. The engineering team investigating the vibe anomaly has made numerous detailed visual inspections of the Webb telescope and has found no visible signs of damage.”

“They are continuing their analysis of accelerometer data to better determine the source of the anomaly.”

The team is measuring and recording the responses of the structure to the fresh low level vibration tests and will compare these new data to results obtained prior to detection of the anomaly.

Work continues over the holidays to ensure Webb is safe and sound and can meet its 2018 launch target. After thoroughly reviewing all the data the team hope to restart the planned vibration and acoustic testing in the new year.

“Currently, the team is continuing their analyses with the goal of having a review of their findings, conclusions and plans for resuming vibration testing in January.”

Webb’s massive optical structure being tested is known as OTIS or Optical Telescope element and Integrated Science. It includes the fully assembled 18-segment gold coated primary mirror and the science instrument module housing the four science instruments

OTIS is a combination of the OTE (Optical Telescope Assembly) and the ISIM (Integrated Science Instrument Module) together.

“OTIS is essentially the entire optical train of the observatory!” said John Durning, Webb Telescope Deputy Project Manager, in an earlier exclusive interview with Universe Today at NASA’s Goddard Space Flight Center.

“It’s the critical photon path for the system.”

The components were fully integrated this past summer at Goddard.

The combined OTIS entity of mirrors, science module and backplane truss weighs 8786 lbs (3940 kg) and measures 28’3” (8.6m) x 8”5” (2.6 m) x 7”10“ (2.4 m).

The environmental testing is being done at Goddard before shipping the huge structure to NASA’s Johnson Space Center in February 2017 for further ultra low temperature testing in the cryovac thermal vacuum chamber.

The 6.5 meter diameter ‘golden’ primary mirror is comprised of 18 hexagonal segments – looking honeycomb-like in appearance.

And it’s just mesmerizing to gaze at – as I had the opportunity to do on a few occasions at Goddard this past year – standing vertically in November and seated horizontally in May.

Each of the 18 hexagonal-shaped primary mirror segments measures just over 4.2 feet (1.3 meters) across and weighs approximately 88 pounds (40 kilograms). They are made of beryllium, gold coated and about the size of a coffee table.

The Webb Telescope is a joint international collaborative project between NASA, the European Space Agency (ESA) and the Canadian Space Agency (CSA).

Webb is designed to look at the first light of the Universe and will be able to peer back in time to when the first stars and first galaxies were forming.

It will also study the history of our universe and the formation of our solar system as well as other solar systems and exoplanets, some of which may be capable of supporting life on planets similar to Earth.

Hydraulic Pump Glitch Aborts NASA’s Hurricane MicroSat Fleet Launch to Dec. 15 – Live Coverage

KENNEDY SPACE CENTER, FL – Monday’s (Dec. 12) planned launch of NASA’s innovative Cyclone Global Navigation Satellite System (CYGNSS) hurricane microsatellite fleet was aborted when a pump in the hydraulic system that releases the Pegasus air-launch booster from its L-1011 carrier aircraft failed in flight. UPDATE: launch delayed to Dec 15, story revised

NASA and Orbital ATK confirmed this afternoon that the launch of the Orbital ATK commercial Pegasus-XL rocket carrying the CYGNSS small satellite constellation has been rescheduled again to Thursday, Dec. 15 at 8:26 a.m. EST from a drop point over the Atlantic Ocean.

Late last night the launch was postponed another day from Dec. 14 to Dec. 15 to solve a flight parameter issue on the CYGNSS spacecraft. New software was uploaded to the spacecraft that corrected the issue, NASA officials said.

“NASA’s launch of CYGNSS spacecraft is targeted for Thursday, Dec. 15,” NASA announced.

“We are go for launch of our #Pegasus rocket carrying #CYGNSS tomorrow, December 15 from Cape Canaveral Air Force Station,” Orbital ATK announced.

“The CYGNSS constellation consists of eight microsatellite observatories that will measure surface winds in and near a hurricane’s inner core, including regions beneath the eyewall and intense inner rainbands that previously could not be measured from space,” according to a NASA factsheet.

Despite valiant efforts by the flight crew to restore the hydraulic pump release system to operation as the L-1011 flew aloft near the Pegasus drop zone, they were unsuccessful before the launch window ended and the mission had to be scrubbed for the day by NASA Launch Director Tim Dunn.

The Pegasus/CYGNSS vehicle is attached to the bottom of the Orbital ATK L-1011 Stargazer carrier aircraft.

The hydraulic release system passed its pre-flight checks before takeoff of the Stargazer.

“Launch of the Pegasus rocket was aborted due to an issue with the launch vehicle release on the L-1011 Stargazer. The hydraulic release system operates the mechanism that releases the Pegasus rocket from the carrier aircraft. The hydraulic system functioned properly during the pre-flight checks of the airplane,” said NASA.

A replacement hydraulic pump system component was flown in from Mojave, California, and successfully installed and checked out. Required crew rest requirements were also met.

The one-hour launch window opens at 8:20 a.m and the actual deployment of the rocket from the L-1011 Tristar is timed to occur 5 minutes into the window at 8:26 a.m.

NASA’s Pegasus/CYGNUS launch coverage and commentary will be carried live on NASA TV – beginning at 7 a.m. EDT

You can watch the launch live on NASA TV at – http://www.nasa.gov/nasatv

Live countdown coverage on NASA’s Launch Blog begins at 6:30 a.m. Dec. 15.

Coverage will include live updates as countdown milestones occur, as well as video clips highlighting launch preparations and the flight.

A prelaunch program by NASA EDGE will begin at 6 a.m.

The weather forecast from the Air Force’s 45th Weather Squadron at Cape Canaveral has significantly increased to predicting a 90% chance of favorable conditions on Thursday, Dec. 15.

The primary weather concerns are for flight cumulus clouds.

The Pegasus rocket cannot fly through rain or clouds due to a negative impact and possible damage on the rocket’s thermal protection system (TPS).

In the event of a delay, the range is also reserved for Friday, Dec. 16 where the daily outlook remains at a 90% chance of favorable weather conditions.

After Stargazer takes off from the Skid Strip early Thursday around 6:30 a.m. EST, it will fly north to a designated drop point box about 126 miles east of Daytona Beach, Florida over the Atlantic Ocean. The crew can search for a favorable launch point if needed, just as they did Monday morning.

The drop box point measures about 40-miles by 10-miles (64-kilometers by 16-kilometers). The flight crew flew through the drop box twice on Monday, about a half an hour apart, as they tried to repair the hydraulic system by repeatedly cycling it on and off and sending commands.

“It was not meeting the prescribed launch release pressures, indicating a problem with the hydraulic pump,” said NASA CYGNSS launch director Tim Dunn.

“Fortunately, we had a little bit of launch window to work with, so we did a lot of valiant troubleshooting in the air. As you can imagine, everyone wanted to preserve every opportunity to have another launch attempt today, so we did circle around the race once, resetting breakers on-board the aircraft, doing what we could in flight to try to get that system back into function again.”

The rocket will be dropped for a short freefall of about 5 seconds to initiate the launch sewuence. It launches horizontally in midair with ignition of the first stage engine burn, and then tilts up to space to begin the trek to LEO.

Here’s a schematic of key launch events:

The $157 million fleet of eight identical spacecraft comprising the Cyclone Global Navigation Satellite System (CYGNSS) system will be delivered to low Earth orbit by the Orbital ATK Pegasus XL rocket.

The nominal mission lifetime for CYGNSS is two years but the team says they could potentially last as long as five years or more if the spacecraft continue functioning.

Pegasus launches from the Florida Space Coast are infrequent. The last once took place over 13 years ago in April 2003 for the GALEX mission.

Typically they take place from Vandenberg Air Force Base in California or the Reagan Test Range on the Kwajalein Atoll.

CYGNSS counts as the 20th Pegasus mission for NASA.

The CYGNSS spacecraft were built by Southwest Research Institute in San Antonio, Texas. Each one weighs approx 29 kg. The deployed solar panels measure 1.65 meters in length.

The solar panels measure 5 feet in length and will be deployed within about 15 minutes of launch.
