NASA’s advanced Global Precipitation Measurement (GPM) weather satellite is continuously tracking and recording the ‘1000 Year’ rainfall event heaping death and devastation across wide areas of South Carolina from the combined actions of a freak Nor’easter and Hurricane Joaquin – which reached a borderline Cat 5 status on Saturday, Oct. 3 with winds of 150 mph.

South Carolina Gov. Nikki Haley declared the historic and torrential rain fall to be a “1000 Year event” on Sunday, Oct. 4. “We have never seen anything like this.” Governor Haley and President Obama issued a “State of Emergency.”

Although the horrendous rains in South Carolina may nearly be done, the nor’easter caused damage estimated to be in the Billions of Dollars and at least 9 storm related deaths as of today, Monday, Oct. 5.

Rainfall totals ranging from 14 to 37 inches in local areas over the past week drenched a wide swath of the Palmetto state with never before seen flooding, according to NASA and NOAA. The most intense periods of rain fell over the weekend.

See herein a gallery of photos from friends and others living through the disaster in South Carolina.

NASA astronaut Scott Kelly also captured dramatic images of Hurricane Joaquin – as I reported earlier here.

A slew of NASA and NOAA orbiting weather satellites are constantly tracking the fierce storms and providing the state and federal governments with the most up to date forecasts to aid officials and emergency responders in evaluating and managing the disaster in the most effective manner possible.

NASA’s GPM and a global fleet of other international weather monitoring satellites gathered measurements every 30 minutes from September 26 to October 5, 2015 that were combined into the eyepoppongly dramatic IMERG (Integrated Multi-satellitE Retrievals for GPM) color-coded video above. It tracks the massive growth, spread and direction of the storms and shows the historic levels of destructive precipitation generated by the lethal pair of powerful storms.

The NASA GPM video shows plumes of moisture from the Nor’Easter and Hurricane Joaquin as they gather force and moved over South Carolina and through the Caribbean around and over the Bahamas and later as Joaquin fortunately veered away from the US eastern seaboard towards Bermuda.

“The IMERG showed highest rainfall totals near 1,000 mm (39.3 inches) in a small area of South Carolina and rainfall between 700 and 900 mm (27.5 and 37.4 inches) over a large area of South Carolina,” says NASA’s Hal Pierce.

Here’s a NASA video with NASA scientist Dalia Kirschbaum describing how GPM can see inside a hurricane to makes rainfall and precipitation measurements in 3D:

Video caption: NASA scientist Dalia Kirschbaum explains how the Global Precipitation Measurement Mission’s Core observatory has an instrument that can see layer by layer through a storm.

The GPM precipitation measurements come from both of its advanced radar instruments – the dual-frequency precipitation (DPR) radar instrument (Ku and Ka band) and the GPM microwave imager (GMI), NASA scientist George Huffman told Universe Today.

The IMERG video is based on an algorithm that also carefully combines and calibrates measurements gathered every 30 minutes from the passive microwave sensors flying aboard a large international constellation of satellites from the US, Europe, Japan and India – and outlined in complete detail further below by NASA’s Huffman and Kirschbaum; exclusively for Universe Today.

The visualization of data was created by NASAs Goddard’s Space Flight Center and shows Hurricane Joaquin around the Bahamas “when it was a tropical storm. Red and green colors show rain and the ice and snow at the top of the storm is visualized in blue.”

“Understanding hurricane structure helps weather forecasters around the world determine a storm’s structure and where it may be going,” says Kirschbaum.

Hurricane Joaquin was still packing winds exceeding 125 mph this morning, but it has lost strength throughout the day.

Over 40,000 homes and businesses are without power today, Oct. 5, in South Carolina due to the unending rain and widespread catastrophic flooding. And many folks had to be evacuated.

Some cemeteries were uprooted with caskets seen floating down flooded streets.

Residents are warned to stay out of the flood waters and standing waters that can be carrying bacteria and diseases presenting a significant health hazard.

In the capitol city of Columbia, there was widespread flooding with severe damage to water mains that cut off drinking water to over 15,000 people.

The governor deployed over 1300 national guard troops to render assistance. Over 150 folks were rescued by helicopter, some from the rooftops of their homes and apartments.

Here’s a helicopter rescue:

Scores of South Carolina residents were getting rescued by canoes and even boats where waters surged in places up to 25 feet above normal.

At least 9 dams have been breached statewide, as well as levees, requiring many thousands people more to be evacuated.

Governor Haley confirmed that over 550 roads were either closed, damaged or destroyed, including back roads and major interstate highways vital to the states and US national economy.

A 70 mile stretch of I-95, a major north-south artery traveled by millions including myself, was closed to all traffic on Sunday and remains closed today. And many side roads that could serve as potential detours are also closed.

Historically high water levels in some of the areas worst hit by flooding has finally receded. But in other areas water levels are rising.

In addition, the US Coast Guard says the cargo ship ‘El Faro’ with 33 people aboard is believed to have sunk because it ventured straight into Hurricane Joaquin. The ship’s crew included 28 Americans and 5 Polish sailors. It sank in the area popularly known as the ‘Bermida Triangle’ in water some 3 miles deep.

Today, the Coast Guard reported the discovery of a debris field over 25-square-miles wide. At least one crew member has already been found dead.

The El Faro set out from the port of Jacksonville on Tuesday when Joaquin was a tropical storm with 85 mph wind speed.

The last distress call on last Thursday morning, as the ship neared the eye of the Hurricane, then a Category 3. The ship was listing over 15 degrees surrounded by 30 foot high waves.

The hurricane quickly grew into a Cat 4 and no further word was heard from the ship. It may be 3 miles underwater at the bottom of the Atlantic Ocean.

How and from which fleet of satellites does NASA obtain the orbital measurements used to create the high resolution, color-coded GPM IMERG visualizations?

“The Integrated Multi-satellitE Retrievals for GPM (IMERG) creates a merged precipitation product from the GPM constellation of satellites. These satellites include DMSPs from the U.S. Department of Defense, GCOM-W from the Japan Aerospace Exploration Agency (JAXA), Megha-Tropiques from the Centre National D’etudies Spatiales (CNES) and Indian Space Research Organization (ISRO), NOAA series from the National Oceanic and Atmospheric Administration (NOAA), Suomi-NPP from NOAA-NASA, and MetOps from the European Organisation for the Exploitation of Meteorological Satellites (EUMETSAT),” NASA scientists George Huffman and Dalia Kirschbaum told me exclusively for Universe Today.

“All of the instruments (radiometers) onboard the constellation partners are intercalibrated with information from the GPM Core Observatory’s GPM Microwave Imager (GMI) and Dual-frequency Precipitation Radar (DPR). The data are gridded at 0.1°x0.1° lat./lon and provided in 30 minute time slices through morphing between satellite overpasses. The satellite estimates are then calibrated with rainfall gauge information.”

Here’s another GPM visualization of Hurricane Joaquin:

Why Was September’s Lunar Eclipse So Dark?

The September 17, 2015 total lunar eclipse - the last of the recent tetrad of lunar eclipses over the past 17 months - was darker than expected. Several factors described below were in play. This photo was taken in Washington's Olympic National Park. Credit: Rick Klawitter

First off, a huge thank you to everyone who made and sent their Danjon scale estimate of the totally-eclipsed Moon’s brightness to Dr. Richard Keen, University of Colorado atmospheric scientist. Your data were crucial to his study of how aerosols in Earth’s atmosphere and other factors influence the Moon’s appearance.

Grateful for your help, Keen received a total of 28 observations from 7 different countries.

Keen — Graph created by Dr. Richard Keen plotting Danjon L values submitted by Universe Today readers and others that compare predicted values (top curve) with observed values.

Using the Danjon information and estimates of the Moon’s brightness using the reverse binocular method, Keen crunched the data and concluded that the Moon was about 0.6 L (Danjon) units darker than expected and 0.4 magnitude dimmer, a brightness reduction of 33%. This agrees well with my own observation and possibly yours, too. No wonder so many stars sparkled near the Moon that night.

Depending on how clear the atmosphere is, the Moon's color can vary dramatically from one eclipse to another. The numbers, called the Danjon Scale, will help you estimate the color of Sunday night's eclipse. Credit: Bob King — Lunar eclipse brightness is rated on the Danjon scale where “0” equals a dark gray totality and “4” a bright, coppery yellow. Credit: Bob King

I think it’s safe to say, most of us expected a normal or even bright totality. So why was it dark? Several factors were at play — one to do with the Moon’s location in Earth’s shadow, the other with a volcanic eruption and a third with long-term, manmade pollution.

During a perigee eclipse, the moon passes more deeply into Earth’s shadow compared to one that happens near apogee, when the moon is most distant from Earth.

You’ll recall that the eclipse occurred during lunar perigee, when the Moon swings closest to Earth in its 27-day orbit. Being closer, it also tracked deeper into Earth’s umbra or inner shadow which narrows the farther back of the planet it goes. An apogean Moon (farthest from Earth) passes through a more tapered cone of darkness closer to the penumbra, where sunlight mixes with shadow. A Moon nearer Earth would find the umbral shadow roomier with the light-leaking penumbra further off in the distance.

But there’s more. Working independently, Steve Albers of NOAA and Brazilian astronomer Helio Vital suggested another reason: aerosols in the atmosphere. “Earth’s stratosphere is no longer completely clean of volcanic ashes,” said Vital in an e-mail communication. “In fact, lingering aerosols (ash, dust, sulfuric acid droplets) from the explosion of Calbuco five months ago may be to blame for that excessive darkening.”

With the lunar horizon in the foreground, the Earth passes in front of the Sun on September 27, 2015 in this simulation, revealing the red ring of sunrises and sunsets along the limb of the planet responsible for illuminating the Moon during the eclipse. The clarity of the stratosphere at eclipse time can greatly affect lunar brightness during totality.

While much of the debris blasted into the stratosphere made for colorful sunsets in the southern hemisphere, some of that material has likely made its way to the northern hemisphere. Albers has noticed an increase in yellow and purple sunsets in his home town of Boulder in recent months, telltale signs of volcanic spew at play.

Forest fires that raged across the western states and Canadian provinces all spring and summer may also have contributed. Most of that smoke usually stays in the lower part of the atmosphere, but some may have found its way to the stratosphere, the very layer responsible for transmitting most of the sunlight that falls into Earth’s shadow and colors the moon.

Sunlight has to pass through these light-absorbing minerals and chemicals on its way through the atmosphere and into Earth’s shadow. Less light means a darker moon during total eclipse. Coincidentally, much of the totally eclipsed Moon passed through the southern half of the umbra which “increased the effectiveness of the Calbuco aerosols (which are still more concentrated in the southern hemisphere than the northern) at dimming the light within the umbra,” writes Keen.

It also so happened that the darkest part of the moon coincided with two vast, dark volcanic plains called Oceanus Procellarum (Ocean of Storms) and Mare Imbrium, artificially enhancing the overall gloom over the northern half of the Moon.

Finally, the human hand may also have played a role in lunar color and brightness. The burning of coal and oil has caused a gradual increase in the amount of human-made sulfate aerosols in the atmosphere since the start of the industrial revolution. According to NASA, at current production levels, human-made sulfate aerosols are believed to outweigh the naturally produced sulfate aerosols. No surprise that the concentration of aerosols is highest in the northern hemisphere where most industrial activity is found.

Isn’t it fascinating that one blood-red Moon can tell us so much about the air we breathe? Thank you again for your participation!

Eclipse By Fire! Smoky Haze Pervades Night Sky, Darkens Moon

The Full Moon at 10:30 p.m. last night (Aug. 30). Even at 25 altitude, it glowed a deep, dark orange due to heavy smoke from western forest fires. Credit: Bob King

Did you see the Moon last night? I walked outside at 10:30 p.m. and was stunned to see a dark, burnt-orange Full Moon as if September’s eclipse had arrived a month early. Why? Heavy smoke from forest fires in Washington, California and Montana has now spread to cover nearly half the country in a smoky pall, soaking up starlight and muting the moonlight.

If this is what global warming has in store for us, skywatchers will soon have to take a forecast of “clear skies” with a huge grain of salt.

By day, the sky appears the palest of blues. By night, the stars are few if any, and the Moon appears faint, the color of fire and strangely remote. Despite last night’s clear skies, only the star Vega managed to penetrate the gloom. I never saw my shadow even at midnight when the Moon had climbed high into the southern sky.

We’ve seen this smoke before. Back in July, Canadian forest fires wafted south and west and covered much of the northern half of the U.S., giving us red suns in the middle of the afternoon and leaving only enough stars to count with two hands at night. On the bright side, the Moon is fascinating to observe. I set up the telescope last night and spend a half hour watching this unexpected “eclipse”; sunsets appear positively atomic. The size of the smoke particles is just right for filtering out or scattering away blues, greens and even yellow from white light. Vivid reds, pinks and oranges remain to tint anything bright enough to penetrate the haze.

But smoke can cause harm, too. Forest fire smoke contains carbon monoxide, carbon dioxide and soot. On especially smoky days, you can even smell the odor of burning trees in the air at ground level. Some may suffer from burning eyes, asthma or bronchitis on especially smoky days even a thousand miles from the source fires.

Above, at a higher elevation, we see through less smoke, so the moonlit sky is a little brighter there. No stars are visible. Credit: Bob King — Wide-angle view of last night’s Moon.

No stars are visible. Credit: Bob King

On clear, blue-sky days, I’ve watched the smoke creep in from the west. It begins a light haze and slowly covers the entire sky in a matter of several hours, often showing a banded structure in the direction of the Sun. A little smoke is OK for observing, but once it’s thick enough to redden the Moon even hours after moonrise, you can forget about using your telescope for stargazing. Sometimes, a passing thunderstorm and cold front clears the sky again. Sometimes not.

The only cures for fire soot are good old-fashioned rain and the colder weather that arrives with fall. In the meantime, many of us will spend our evenings reading about the stars instead of looking at them.

Catching Earth at Aphelion

Do you feel a little… distant today? The day after the 4^th of July weekend brings with it the promise of barbecue leftovers and discount fireworks. It also sees our fair planet at aphelion, or its farthest point from the Sun. In 2015, aphelion (or apoapsis) occurs at 19:40 Universal Time (UT)/3:40 PM EDT today, as we sit 1.01668 astronomical units (AU) from the Sun. This translates to 152.1 million kilometres, or 94.5 million miles. We’re actually 3.3% closer to the Sun in early January than we are today. This also the latest aphelion has occurred on the calendar year since 2007, and it won’t fall on July 6^th again until 2018. The insertion of an extra day every leap year causes the date for Earth aphelion to slowly vary between July 3^rd and July 6^th in the current epoch.

Aphelion sees the Earth 4.8 million kilometers farther from the Sun than perihelion in early January. The eccentricity of our orbit—that is, how much our planet’s orbit varies from circular to elliptical—currently sits at 0.017 or 1.7%.

It is ironic that we’re actually farther from the Sun in the middle of northern hemisphere summer. It sure doesn’t seem like it on a sweltering Florida summer day, right? That’s because the 23.44 degree tilt of the Earth’s rotational axis is by far the biggest driver of the seasons. But our variation in distance from the Sun does play a factor in long term climate as well. We move a bit slower farther from the Sun, assuring northern hemisphere summers are currently a bit longer (by about 4 days) than winters. The variation in solar insolation between aphelion and perihelion currently favors hot dry summers in the southern hemisphere.

But these factors are also slowly changing as well.

The eccentricity of our orbit varies from between 0.000055 and 0.0679 over a span of a ‘beat period’ of 100,000 years. Our current trend sees eccentricity slowly decreasing.

The tilt of our rotational axis varies between 22.1 and 24.5 degrees over 41,000 years. This value is also currently on a decreasing trend towards its shallow minimum around 11,800 AD.

And finally, the precession of the Earth’s axis and apsidal precession combine to slowly move the date of aphelion and perihelion one time around our calendar once every 21,000 years.

These combine to form what are known as Milankovitch Cycles of long-term climate variation, which were first expressed by astronomer Milutin Milankovic in 1924. Anthropogenic climate change is a newcomer on the geologic scene, as human civilization does its very best to add a signal of its very own to the mix.

We also just passed the mid-point ‘pivot of the year’ on July 2nd. More than half of 2015 is now behind us.

Want to observe the aphelion and perihelion of the Earth for yourself? If you have a filtered rig set to photograph the Sun, try this: take an image of the Sun today, and take another on perihelion next year on January 2nd. Be sure to use the same settings, so that the only variation is the angular size of the Sun itself. The disk of the Sun varies from 33’ to 31’ across. This is tiny but discernible. Such variations in size between the Sun and the Moon can also mean the difference between a total solar and annular eclipse.

Should we term the aphelion Sun a #MiniSol? Because you can never have too many internet memes, right?

And did you know: the rotational axis of the Sun is inclined slightly versus the plane of the ecliptic to the tune of 7.25 degrees as well. In 2015, the Sun’s north pole was tipped our way on March 7^th, and we’ll be looking at the south pole of our Sun on September 9^th.

And of course, seasons on other planets are much more extreme. We’re just getting our first good looks at Pluto courtesy of New Horizons as it heads towards its historic flyby on July 14^th. Pluto reached perihelion in 1989, and is headed towards aphelion 49 AU from the Sun on the far off date in 2114 AD. Sitting on Pluto, the Sun would shine at -19th magnitude—about the equivalent of the twilight period known as the ‘Blue Hour’ here on Earth—and the Sun would appear a scant one arc minute across, just large enough to show a very tiny disk.

All thoughts to consider as we start the long swing inward towards perihelion next January.

Happy aphelion!

Space Weather Storm Monitoring Satellite Blasts off for Deep Space on SpaceX Rocket

NOAA's DSCOVR satellite launches from Cape Canaveral Air Force Station on Feb. 11, 2015. DSCOVR will provide NOAA space weather forecasters more reliable measurements of solar wind conditions, improving their ability to monitor potentially harmful solar activity. Credit: Alan Walters/AmericaSpace

After a 17 year long wait, a new American mission to monitor intense solar storms and warn of impeding space weather disruptions to vital power grids, telecommunications satellites and public infrastructure was launched atop a SpaceX Falcon 9 on Wednesday, Feb. 11, from Cape Canaveral, Florida, to start a million mile journey to its deep space observation post.

The third time proved to be the charm when the Deep Space Climate Observatory, or DSCOVR science satellite lifted off at 6:03 p.m. EST Wednesday from Space Launch Complex 40 at Cape Canaveral Air Force Station in Florida.

The spectacular sunset blastoff came after two scrubs this week forced by a technical problem with the Air Force tracking radar and adverse weather on Sunday and Tuesday.

The $340 million DSCOVR has a critical mission to monitor the solar wind and aid very important forecasts of space weather at Earth at an observation point nearly a million miles from Earth. It will also take full disk color images of the sunlit side of Earth at least six times per day that will be publicly available and “wow” viewers.

The couch sized probe was targeted to the L1 Lagrange Point, a neutral gravity point that lies on the direct line between Earth and the sun located 1.5 million kilometers (932,000 miles) sunward from Earth. At L1 the gravity between the sun and Earth is perfectly balanced and the satellite will orbit about that spot just like a planet.

L1 is a perfect place for the science because it lies outside Earth’s magnetic environment. The probe will measure the constant stream of solar wind particles from the sun as they pass by.

The DSCOVR spacecraft (3-axis stabilized, 570 kg) will be delivered to the Sun-Earth L1 point, 1.5 million km (1 million miles) from the Earth, directly in front of the Sun. A Halo (Lissajous) orbit will stabilize the craft's position around the L1 point while keeping it outside the radio noise emanating from the Sun.

DSCOVR is a joint mission between NOAA, NASA, and the U.S Air Force (USAF) that will be managed by NOAA. The satellite and science instruments are provided by NASA and NOAA. The rocket was funded by the USAF.

The mission is vital because its solar wind observations are crucial to maintaining accurate space weather forecasts to protect US infrastructure such as power grids, aviation, planes in flight, all types of Earth orbiting satellites for civilian and military needs, telecommunications, ISS astronauts and GPS systems.

It will take about 150 days to reach the L1 point and complete satellite and instrument checkouts.

DSCOVR will then become the first operational space weather mission to deep space and function as America’s primary warning system for solar magnetic storms.

It will replace NASA’s aging Advanced Composition Explorer (ACE) satellite which is nearly 20 years old and far beyond its original design lifetime.

“DSCOVR is the latest example of how NASA and NOAA work together to leverage the vantage point of space to both understand the science of space weather and provide direct practical benefits to us here on Earth,” said John Grunsfeld, associate administrator of NASA’s Science Mission Directorate in Washington.

DSCOVR was first proposed in 1998 by then US Vice President Al Gore as the low cost ‘Triana’ satellite to take near continuous views of the Earth’s entire globe to feed to the internet as a means of motivating students to study math and science. It was eventually built as a much more capable Earth science satellite that would also conduct the space weather observations.

But Triana was shelved for purely partisan political reasons and the satellite was placed into storage at NASA Goddard and the science was lost until now.

DSCOVR is equipped with a suite of four continuously operating solar science and Earth science instruments from NASA and NOAA.

It will make simultaneous scientific observations of the solar wind and the entire sunlit side of Earth.

The 750-kilogram (1250 pound) DSCOVR probe measures 54 inches by 72 inches.

The two Earth science instruments from NASA are the Earth Polychromatic Imaging Camera (EPIC) and the National Institute of Standards and Technology Advanced Radiometer (NISTAR).

EPIC will provide true color spectral images of the entire sunlit face of Earth at least six times per day, as viewed from an orbit around L1. They will be publically available within 24 hours via NASA Langley.

It will view the full disk of the entire sunlit Earth from sunrise to sunset and collect a variety of science measurements including on ozone, aerosols, dust and volcanic ash, vegetation properties, cloud heights and more.

Listen to my post launch interview with the BBC about DSCOVR and ESA’s successful IXV launch on Feb. 11.

A secondary objective by SpaceX to recover the Falcon 9 first stage booster on an ocean going barge had to be skipped due to very poor weather and very high waves in the Atlantic Ocean making a safe landing impossible. The stage did successfully complete a soft landing in the ocean.

Stay tuned here for Ken’s continuing Earth and planetary science and human spaceflight news.

What Could Explain the Mysterious Ring in Antarctica?

Ever since its discovery was announced earlier this year, the 3 km-wide ring structure discovered on the of Antarctica has been a source of significant interest and speculation. Initially, the discovery was seen as little more than a happy accident that occurred during a survey of East Antarctica by a WEGAS (West-East Gondwana Amalgamation and its Separation) team from the Alfred Wegener Institute.

However, after the team was interviewed by the Brussels-based International Polar Foundation, news of the find and its possible implication spread like wildfire. Initial theories for the possible origin of the ring indicated that it could be the result of the impact of a large meteor. However, since the news broke, team leader Olaf Eisen has offered an alternative explanation: that the ring structure is in fact the result of other ice-shelf processes.

As Eisen indicated in a new entry on the AWI Ice Blog: “Doug MacAyeal, glaciologist from the University of Chicago, put forward the suggestion that the ring structure could be an ice doline.” Ice dolines are round sinkholes that are caused by a pool of melt water formed within the shelf ice. They are formed by the caving in of ice sheets or glaciers, much in the same way that sinkholes form over caves.

“If the melt water drains suddenly,” he wrote, “like it often does, the surface of the glacier is destabilised and does collapse, forming a round crater. Ice depressions like this have been observed in Greenland and on ice shelves of the Antarctic Peninsula since the 1930s.”

However, in glaciers, these cavities form much more rapidly, as the meltwater created by temperature variations causes englacial lakes or water pockets to from which then drains through the ice sheet. Such dolines have been observed for decades, particularly in Greenland and the Antarctic Peninsula where the ice melts during the summertime.

Initial analysis of satellite images appear to confirm this, as they indicate that the feature could have been present before the supposed impact took place around 25 years ago. In addition, relying on data from Google Maps and Google Earth, the WEGAS (West-East Gondwana Amalgamation and its Separation) team observed that the 3 km ring is accompanied by other, smaller rings.

Such formations are inconsistent with meteorite impacts, which generally leave a single crater with a raised center. And as a general rule, these craters also measure between ten to twenty times the size of the meteorite itself – in this case, that would mean a meteorite 200 meters in diameter. This would mean that, had the ring structure been caused by a meteorite, it would have been the largest Antarctic meteor impact on record.

It is therefore understandable why the announcement of this ring structure triggered such speculation and interest. Meteorite impacts, especially record-breaking ones are nothing if not a hot news item. Too bad this does not appear to be the case.

However, the possibility that the ring structure is the result of an ice doline raises a new host of interesting questions. For one, it would indicate that dolines are much more common in East Antarctica than previously thought. Ice dolines were first noticed in the regions of West Antarctica and the Antarctic Peninsula, where rapid warming is known to take place.

East Antarctica, by contrast, has long been understood to be the coldest, windiest and driest landmass on the planet. Knowing that such a place could produce rapid warming that would lead to the creation of a significant englacial lake would certainly force scientists to rethink what they know about this continent.

“To form an ice doline this size, it would need a considerable reservoir of melt water,” Eisen said. “Therefore we would need to ask, where did all this melt water come from? Which melting processes have caused such an amount of water and how does the melting fit into the climate pattern of East Antarctica?”

In the coming months, Eisen and the AWI scientists plant to analyze the data from the Polar 6 (Eisen’s mission) measurements thoroughly, in the hopes of getting all the facts straight. Also, Jan Lenaerts – a Belgian glaciologist with AWI – is planning an land-based expedition to the site; which unfortunately due to the short Antarctic summer season and the preparation time needed won’t be taking place until the end of 2015.

But what is especially interesting, according to Eisen, is the rapid pace at which the debate surrounding the ring structure occurred. Within days of their announcement, the WEGAS team was astounded by the nature of the debate taking place in the media and on the internet (particularly Facebook), bringing together glaciologists from all around the world.

As Eisen put it in his blog entry, “For the WEGAS team, however, our experience of the last few days has shown that modern scientific discussion is not confined to the ivory towers of learned meetings, technical papers, and lecture halls, but that the public and social media play a tremendous role. For us, cut off from the modern world amongst the eternal ice, this new science seems to have happened at an almost breathtaking pace.”

This activity brought the discussion about the nature of the ring structure forward by several weeks, he claims, focusing attention on the true causes of the surprise discovery itself and comparing and contrasting possible theories.

NOAA/NASA/USAF Deep Space Climate Observatory (DSCOVR) Launching Feb. 8 to Monitor Solar Winds

The long awaited Deep Space Climate Observatory, or DSCOVR science satellite is slated to blast off atop a SpaceX Falcon 9 on Sunday, Feb. 8, from Cape Canaveral, Florida on a mission to monitor the solar wind and aid very important forecasts of space weather at Earth.

DSCOVR is a joint mission between NOAA, NASA, and the U.S Air Force (USAF) that will be managed by NOAA. The satellite and science instruments are provided by NASA and NOAA.

Update Feb 8: Hold, Hold, Hold !!! 6:10 PM 2/8/15 Terminal Count aborted at T Minus 2 min 26 sec due to a tracking issue. NO launch of Falcon 9 today. rocket being safed now. next launch opportunity is Monday. Still TBD.

The rocket is provided by the USAF. SpaceX will try to recover the first stage via a guided descent to a floating barge in the Atlantic Ocean.

The weather outlook is currently very promising with a greater than 90 percent chance of favorable weather at launch time shortly after sunset on Sunday which could make for a spectacular viewing opportunity for spectators surrounding the Florida Space coast.

Liftoff atop the SpaceX Falcon 9 rocket is targeted for at 6:10:12 p.m. EST on Feb. 8, from Cape Canaveral Air Force Station Space Launch Complex 40.

There is an instantaneous launch window, meaning that any launch delay due to weather, technical or other factors will force a scrub to Monday.

The launch will be broadcast live on NASA TV: http://www.nasa.gov/nasatv

NASA’s DSCOVR launch blog coverage of countdown and liftoff will begin at 3:30 p.m. Sunday.

“DSCOVR is NOAA’s first operational space weather mission to deep space,” said Stephen Volz, assistant administrator of the NOAA Satellite and Information Service in Silver Spring, Maryland, at the pre-launch briefing today (Feb. 7) at the Kennedy Space Center in Florida.

The mission of DSCOVR is vital because its solar wind observations are crucial to maintaining accurate space weather forecasts to protect US infrastructure from disruption by approaching solar storms.

“DSCOVR will maintain the nation’s solar wind observations, which are critical to the accuracy and lead time of NOAA’s space weather alerts, forecasts, and warnings,” according to a NASA description.

“Space weather events like geomagnetic storms caused by changes in solar wind can affect public infrastructure systems, including power grids, telecommunications systems, and aircraft avionics.”

DSCOVR will replace NASA’s aging Advanced Composition Explorer (ACE) satellite which is nearly 20 years old and far beyond its original design lifetime.

The couch sized probe is being targeted to the L1 Lagrange Point, a neutral gravity point that lies on the direct line between Earth and the sun located 1.5 million kilometers (932,000 miles) sunward from Earth. At L1 the gravity between the sun and Earth is perfectly balanced and the satellite will orbit about that spot just like a planet.

L1 is a perfect place for the science because it lies outside Earth’s magnetic environment. The probe will measure the constant stream of solar wind particles from the sun as they pass by.

This will enable forecasters to give a 15 to 60 minute warning of approaching geomagnetic storms that could damage valuable infrastructure.

DSCOVR is equipped with a suite of four continuously operating solar science and Earth science instruments from NASA and NOAA.

It will make simultaneous scientific observations of the solar wind and the entire sunlit side of Earth.

Three instruments will help measure the solar wind on the DSCOVR mission: (shown from left to right), the Faraday cup to monitor the speed and direction of positively-charged solar wind particles, the electron spectrometer to monitor electrons, and a magnetometer to measure magnetic fields.

The 750-kilogram DSCOVR probe measures 54 inches by 72 inches.

I saw the DSCOVR spacecraft up close at NASA Goddard Space Flight Center in Maryland last fall during processing in the clean room.

A secondary objective of the rocket launch for SpaceX is to conduct their second attempt to recover the Falcon 9 first stage booster on an ocean going barge. Read my articles about the first attempt in January 2015, starting here.

It was originally named ‘Triana’ (aka Goresat) and was conceived by then US Vice President Al Gore as a low cost satellite to take near continuous views of the Earth’s entire globe to feed to the internet as a means of motivating students to study math and science. It was eventually built as a much more capable Earth science satellite as well as to conduct the space weather observations.

But Triana was shelved for purely partisan political reasons and the satellite was placed into storage and the science was lost until now.

NASA Launches Revolutionary Earth Science Satellite Measuring Soil Moisture Cycle

NASA’s Soil Moisture Active Passive (SMAP) observatory, on a United Launch Alliance Delta II rocket, is seen after the mobile service tower was rolled back Friday, Jan. 30 at Space Launch Complex 2, Vandenberg Air Force Base, Calif.

Story updated[/caption]

At dawn this morning (Jan. 31) NASA launched an advanced Earth science satellite aimed at making measurements of our planet’s surface soil moisture and freeze/thaw states from space that will revolutionize our understanding of the water, energy, and carbon cycles driving all life on Earth, aid weather forecasting and improve climate change models.

NASA’s new Soil Moisture Active Passive (SMAP) observatory thundered off the pad at 6:22 a.m. PST (9:22 a.m. EST) Saturday atop a two stage United Launch Alliance Delta II rocket from Space Launch Complex 2 on Vandenberg Air Force Base, California.

The $916 million satellite successfully separated from the rocket’s second stage some 57 minutes after the flawless liftoff and was injected into an initial 411- by 425-mile (661- by 685-kilometer) orbit. The spacecraft then deployed its solar arrays and telemetry indicated it was in excellent health.

“We’re in contact with SMAP and everything looks good right now,” NASA Launch Manager Tim Dunn said.

“Deployment of the solar arrays is underway. We just couldn’t be happier.”

SMAP separated from the second stage while pointed toward the sun as seen in the video below from a rocket mounted camera:

SMAP is NASA’s 1st Earth observing satellite designed to make high resolution global observations of Earth’s vital surface soil moisture content and freeze/thaw cycle just below your feet. It will aid global forecasting and have broad applications for science and society.

SMAP’s combined radar and radiometer instruments will peer into the top 2 inches (5 centimeters) of soil, through clouds and moderate vegetation cover, day and night, to produce the highest-resolution, most accurate soil moisture maps ever obtained from space, says NASA.

The blastoff of SMAP successfully concluded NASA’s ambitious plans to launch a record breaking total of five Earth science satellites in less than a year’s time.

“The launch of SMAP completes an ambitious 11-month period for NASA that has seen the launch of five new Earth-observing space missions to help us better understand our changing planet,” said NASA Administrator Charles Bolden.

“Scientists and policymakers will use SMAP data to track water movement around our planet and make more informed decisions in critical areas like agriculture and water resources.”

SMAP is projected to last for at least a three year primary mission.

The prior NASA Earth science instrument launched was the Cloud Aerosol Transport System (CATS) payload hauled to space by the SpaceX CRS-4 Dragon on Jan. 10, 2015 and recently installed on the exterior of the ISS. Read my CATS installation story – here.

The three earlier NASA Earth science missions launched over the past year included ISS-RapidScat in September 2014, the Global Precipitation Measurement (GPM) Core Observatory, a joint mission with the Japan Aerospace Exploration Agency, in February 2014, and the Orbiting Carbon Observatory-2 (OCO-2) carbon observatory in July 2014.

“Congratulations to the NASA Launch Services Program team, JPL and all of our mission partners on today’s successful launch of the SMAP satellite,” said Jim Sponnick, ULA vice president, Atlas and Delta Programs.

“It is our honor to launch this important Earth science mission to help scientists observe and predict natural hazards, and improve our understanding of Earth’s water, energy and carbon cycles.”

SMAP will provide high-resolution, space-based measurements of soil moisture and its state — frozen or thawed — a new capability that will allow scientists to better predict natural hazards of extreme weather, climate change, floods and droughts, and help reduce uncertainties in our understanding of Earth’s water, energy and carbon cycles, according to a NASA description.

The mission will map the entire globe every two to three days for at least three years and provide the most accurate and highest-resolution maps of soil moisture ever obtained. The spacecraft’s final circular polar orbit will be 426 miles (685 kilometers), at an inclination of 98.1 degrees. The spacecraft will orbit Earth once every 98.5 minutes and repeat the same ground track every eight days.

“All subsystems are being powered on and checked out as planned,” Kent Kellogg, the SMAP project manager, during a post-launch press conference.

“Communications, guidance and control, computers and power are all operating nominally.”

The observatory is in excellent health. Its instruments will be turned on in 11 days.

Today’s blastoff of SMAP marks ULA’s second successful launch this month as well as the second of 13 planned for 2015. ULA’s first launch of 2015 was MUOS-3 from Cape Canaveral on Jan. 20.

ULA’s next launch involves NASA’s Magnetospheric Multiscale Mission (MMS) to study Earth’s magnetic reconnection. It is scheduled for launch on an Atlas V 421 booster on March 12 from Cape Canaveral. See my up close visit with MMS and NASA Administrator Charles Bolden at NASA Goddard Space Flight Center detailed in my story – here.

NEW JERSEY – Record breaking snow from the ‘Blizzard of 2015’ hit vast regions of the US Northeast today, Jan. 27, 2015, stretching from Long Island to New England.

NASA and NOAA Earth orbiting satellites are keeping track of the storm affecting millions of residents.

This afternoon the agencies provided a new set of night-time and daytime views of the Blizzard of 2015 taken by the Suomi NPP and the GOES-East satellites.

The crippling blizzard is causing misery, extensive destruction to homes and businesses in localized areas, power outages, traffic accidents, breaks in some sea walls and deaths.

The satellite image above shows a combination of the day-night band and high resolution infrared imagery from the NASA-NOAA’s Suomi NPP satellite.

It was taken as the historic blizzard neared peak intensity as it moved over the New York area and through the Boston Metropolitan areas at 06:45Z (1:45 a.m. EST) on January 27, 2015.

The high cloud tops from the most intense parts of the storm blurred the regions normally bright nighttime lights in the satellite image.

Although the snow totals were about half the over two feet forecast for the New York Metropolitan region, many areas to the north and east were inundated with very heavy to historic snow fall totals, as bad or worse than the forecasters predicted.

Over two feet of snow fell on areas of New York’s Long Island and stretching north to vast regions of Connecticut, Massachusetts, New Hampshire and into Maine.

Near hurricane force waves are crashing into some coastal towns along the Massachusetts shoreline. Wind gusts as high as 78 mph have been recorded.

“Highest snowfall report has been Auburn, MA with 32.5 inches! Wind gust reports as high as 78 mph in Nantucket, MA,” according to a tweet this evening from the National Weather Service (NWS).

Worchester, Mass had a record breaking 31 inches of snow. And it’s still falling this evening in the 2nd largest city in New England.

A flood emergency is in effect in Marshfield, Mass., where an 80 foot section of the seawall was smashed by crashing waves and is destroying homes as shown on NBC Nightly News.

Blinding snow is raging in Portland, Maine this evening according on a live NBC News report.

“At 10 a.m. EST, the National Weather Service noted “the powerful nor’easter that brought moderate to heavy snowfall and blizzard conditions to the Northeast on Monday will continue to affect the region on Tuesday, with heavy snow and blizzard conditions expected from eastern Long Island to Maine as the system slowly moves to the northeast. Snow and strong winds will being tapering off from south to north Tuesday night into Wednesday morning,” wrote NASA’s Rob Gutro of NASA’s Goddard Space Flight Center in an update.

“Later on January 27, 2015 at 17:35 UTC (12:35 p.m. EST) NOAA’s Geostationary Operational Environmental or GOES-East satellite captured an image of the nor’easter over New England. The image was created by the NASA/NOAA GOES Project and showed the clouds associated with the nor’easter blanketing New England. An occluded front extended north and eastward out of the low pressure area’s center out into the Atlantic Ocean.”

The latest NOAA forecast as of 4 PM, Jan. 27 states:

HIGH WINDS AND HEAVY SNOW WILL BEGIN TO GRADUALLY TAPER OFF FROM SOUTH TO NORTH TONIGHT…BUT WILL LAST INTO EARLY WEDNESDAY MORNING ACROSS PORTIONS OF MAINE. HEAVY SNOWFALL WILL COMBINE WITH SUSTAINED WINDS OF 30 TO 40 MPH…AND GUSTS IN EXCESS OF 50 MPH…TO CREATE LIFE-THREATENING WHITEOUT OR BLIZZARD CONDITIONS. THESE WINDS MAY LEAD TO DOWNED TREES AND POWER LINES RESULTING IN POWER OUTAGES. TRAVEL WILL BE IMPOSSIBLE AND LIFE-THREATENING IN MANY AREAS. ALONG THE IMMEDIATE COASTLINE…WIND GUSTS TO NEAR 65 MPH WILL BE POSSIBLE. COASTAL FLOODING AND SEVERE BEACH EROSION WILL ALSO BE A POSSIBILITY…AND VULNERABLE ROADS AND STRUCTURES MAY BE FLOODED OR DAMAGED.
