UPDATE: The launch of Cygnus has been delayed until no earlier than January 7, 2014 due to the coolant leak at the International Space Station and necessary spacewalks to fix the problem. You can read more about the issue here and here.

WALLOPS ISLAND, VA – Orbital Sciences Corp. is marching forward with plans for a spectacular night blastoff of the firms privately developed Antares rocket and Cygnus cargo spacecraft on Thursday, Dec. 19 from a seaside pad at Wallops Island, Virginia on a mission for NASA that’s bound for the International Space Station (ISS).

The nighttime Antares liftoff is currently scheduled for prime time – at 9:19 p.m. EST from Launch Pad 0A at the Mid-Atlantic Regional Spaceport (MARS) at NASA Wallops Island, Virginia. It should be easily visible to tens of millions of residents along a wide swath of the US East Coast spanning from South Carolina to southern Maine – weather permitting.

Here’s our guide on “How to See the Antares/Cygnus Dec. 19 Night Launch” – with your own eyes – complete with viewing maps and trajectory graphics from a variety of prime viewing locations; including Philadelphia, NYC, Baltimore and historic landmarks in Washington, DC.

Update: launch postponed to mid-January 2014 to allow NASA astronauts to conduct 3 EVA’s to swap out the ammonia pump module and restore full cooling capacity to the ISS

It will be visible to spectators inland as well, stretching possibly into portions of West Virginia and western Pennsylvania.

For example; Here’s the expected view from Rocky’s famous workout on the steps of the Philadelphia Art Museum.

The viewing maps are courtesy of Orbital Sciences, the private company that developed both the Antares rocket and Cygnus resupply vessel aimed at keeping the ISS fully stocked and operational for science research.

Up top is the map showing the maximum elevation the rocket will reach in the eastern United States.

The flight is designated the Orbital-1, or Orb-1 mission.

Orb-1 is the first of eight commercial cargo resupply missions to the ISS by Orbital according to its Commercial Resupply Services (CRS) contract with NASA.

Of course you can still view the launch live via the NASA TV webcast.

This marks the maiden night launch of the two stage Antares rocket following a pair of daytime test and demonstration launches earlier this year, in April and September.

It’s important to note that the Dec. 19 liftoff is still dependent on NASA engineers resolving the significant issue with the ammonia cooling system that popped up late last week when a critical flow control valve malfunctioned.

If the pump valve can’t be brought back online, two American astronauts may make two or three unscheduled spacewalks starting later this week.

So in the event spacewalks are required, Antares launch could still slip a few days to the end of the launch window around Dec. 21 or Dec. 22. Thereafter the launch would be postponed until January 2014.

Here’s your chance to witness a mighty rocket launch – from the comfort of your home and nearby locations along the east coast.

And its smack dab in the middle of the Christmas and holiday season resplendent with shining bright lights.

Weather outlook appears rather promising at this time – 95% favorable chance of lift off.

The rocket was rolled out to the Wallops launch pad this morning by Orbital’s technicians.

Cygnus is loaded with approximately 1465 kg (3,230 lbs.) of cargo for the ISS crew for NASA.

NASA Television coverage of the Antares launch will begin at 8:45 p.m. on Dec. 19 – www.nasa.gov/ntv

Stunning Movie Shows What Earth Looks Like to an Incoming Spacecraft

When NASA’s Juno spacecraft flew past Earth in October of this year, it focused some of its cameras on the Earth-Moon system. Immediately after the flyby, images taken by the Junocam were released, but today, NASA released an amazing video taken by the Advanced Stellar Compass (ASC) camera, a low-light camera that is primarily used as a star tracking a navigation tool. Over the course of three days, it captured the orbital ballet-like dance between the Earth and Moon.

“This is profound, and I think our movie does the same thing as “Pale Blue Dot” image from Voyager, except it’s a movie instead of an image,” said Scott Bolton, Juno principal investigator, speaking during a press briefing from the American Geophysical Union conference today in San Fransisco. “Like Carl Sagan said, everything we know is on this dot. To me this says, ‘we’re all in this together.’”

The Oct. 9 flyby was a gravity assist, accelerating Juno out of the inner solar system and toward Jupiter’s orbit. The probe is expected to arrive at Jupiter on July 4, 2016.

The movie begins at 2:00 UTC on Oct. 6, more than four days before Juno’s closest approach, when the spacecraft was approximately 2.1 million miles (3.3 million kilometers) from Earth. Earth’s moon is seen transiting in front of our planet, and then moves out of frame toward the right as Juno enters the space inside the orbit of our natural satellite. As Juno gets closer to Earth, hints of clouds and continents are visible before the planet’s brightness overwhelms the cameras, which were not designed to image so bright an object. The sequence ends as Earth passes out of view, which corresponds to approximately 17:35 UTC Oct. 9 when Juno was at an altitude of about 47,000 miles (76,000 kilometers) above Earth’s surface.

“From a half-million kilometers out, the Moon is dark as charcoal and but Earth way brighter, as a shiny blue dot,” said John Joergensen, who lead the team that designed the star tracking cameras. “It’s amazing to think that all of humanity being scanned in this movie, and to see how small the Moon is relative to Earth.”

The cameras that took the images for the movie are located near the pointed tip of one of the spacecraft’s three solar-array arms. They are part of Juno’s Magnetic Field Investigation (MAG) and are normally used to determine the orientation of the magnetic sensors. These cameras look away from the sunlit side of the solar array, so as the spacecraft approached, the system’s four cameras pointed toward Earth. Earth and the moon came into view when Juno was about 600,000 miles (966,000 kilometers) away — about three times the Earth-moon separation.

During the flyby, timing was everything. Juno was traveling about twice as fast as a typical satellite, and the spacecraft itself was spinning at 2 rpm. To assemble a movie that wouldn’t make viewers dizzy, the star tracker had to capture a frame each time the camera was facing Earth at exactly the right instant. The frames were sent to Earth, where they were processed into video format.

As Juno is a spinning spacecraft, the images were aligned to remove their apparent rotation. The original ASC images are monochrome; faint coloration has been added by converting the measured grayscale values into false colors matching a true color image of Earth.

Um, something in my eye. This wonderful video details a what took place when the Jupiter-bound Juno spacecraft swung past Earth on Oct. 9, 2013 for a gravity assist, and amateur radio operators around the world sent a Morse Code saying “HI” to the spacecraft.

“We wanted to know, if this were an interplanetary spacecraft, could they we tell there was intelligent life on Earth?” said Bill Kurth, co-investigator for the Juno Waves Investigation from the University of Iowa.

Watch the video to find out if it worked.

“We obviously haven’t heard anything like this from any other planet,” said Scott Bolton, Juno principal investigator, speaking during a press briefing from the American Geophysical Union conference today in San Fransisco.

And the Coldest Place on Earth Is …

With remote-sensing satellites, scientists have found the coldest places on Earth, just off a ridge in the East Antarctic Plateau. The coldest of the cold temperatures dropped to minus 135.8 F (minus 93.2 C) -- several degrees colder than the previous record. Image Credit: Ted Scambos, National Snow and Ice Data Center.

What is the coldest place on Earth? Scientists say it’s a place so cold that ordinary mercury or alcohol thermometers won’t work there. If you were there, every breath would be painful, your clothing would crackle every time you moved, and if you threw hot water into the air, it would fall to the ground as tiny shards of ice. At this place, the new record of minus 136 F (minus 93.2 C) was set on Aug. 10, 2010. Researchers analyzed data from several satellite instruments and found the coldest place on Earth in the past 32 years is … a high ridge in Antarctica between Dome Argus and Dome Fuji, two summits on the ice sheet known as the East Antarctic Plateau. Temperatures in several hollows were found to dip to the new record.

“We had a suspicion this Antarctic ridge was likely to be extremely cold,” said Ted Scambos, from the National Snow and Ice Data Center in Boulder, Colorado. “With the launch of Landsat 8, we finally had a sensor capable of really investigating this area in more detail.”

This beats out the previous low of minus 128.6 F (minus 89.2 C), set in 1983 at the Russian Vostok Research Station in East Antarctica. The coldest permanently inhabited place on Earth is northeastern Siberia, where temperatures in the towns of Verkhoyansk and Oimekon dropped to a bone-chilling 90 degrees below zero Fahrenheit (minus 67.8 C) in 1892 and 1933, respectively.

Scambos and his team made the discovery while analyzing the most detailed global surface temperature maps to date, developed with data from remote sensing satellites. The new findings were reported at the American Geophysical Union meeting in San Francisco.

The pursuit to find the coldest place on Earth started when the researchers were studying large snow dunes, sculpted and polished by the wind, on the East Antarctic Plateau. When the scientists looked closer, they noticed cracks in the snow surface between the dunes, possibly created when wintertime temperatures got so low the top snow layer shrunk. This led scientists to wonder what the temperature range was, and prompted them to hunt for the coldest places using data from two types of satellite sensors.

They used data from the Moderate Resolution Imaging Spectroradiometer (MODIS) instruments on NASA’s Terra and Aqua satellites and the Advanced Very High Resolution Radiometer (AVHRR) on several National Oceanic and Atmospheric Administration satellites. These sensitive instruments can pick up thermal radiation emitted from Earth’s surface, even in areas lacking much heat.

Using these sensors to scan the East Antarctic Plateau, Scambos detected extremely cold temperatures on a 620-mile stretch of the ridge at high elevations between Argus and Fuji, and even colder temperatures lower elevations in pockets off the ridge. Then, with the higher resolution of the Thermal Infrared Sensor (TIRS) aboard Landsat 8, the research team pinpointed the record-setting pockets.

The team compared the sites to topographic maps to explore how it gets so cold. Already cold temperatures fall rapidly when the sky clears. If clear skies persist for a few days, the ground chills as it radiates its remaining heat into space. This creates a layer of super-chilled air above the surface of the snow and ice. This layer of air is denser than the relatively warmer air above it, which causes it to slide down the shallow slope of domes on the Antarctic plateau. As it flows into the pockets, it can be trapped, and the cooling continues.

“By causing the air to be stationary for extended periods, while continuing to radiate more heat away into space, you get the absolute lowest temperatures we’re able to find,” Scambos said. “We suspected that we would be looking for one magical site that got extremely cold, but what we found was a large strip of Antarctica at high altitude that regularly reached these record low temperatures.”

Heat Shield for 2014 Orion Test Flight Arrives at Kennedy Aboard NASA’s Super Guppy

KENNEDY SPACE CENTER, FL – The heat shield crucial to the success of NASA’s 2014 Orion test flight has arrived at the Kennedy Space Center (KSC) aboard the agency’s Super Guppy aircraft – just spacious enough to fit the precious cargo inside.

Orion is currently under development as NASA’s next generation human rated vehicle to replace the now retired space shuttle. The heat shields advent is a key achievement on the path to the spacecraft’s maiden flight.

“The heat shield which we received today marks a major milestone for Orion. It is key to the continued assembly of the spacecraft,” Scott Wilson, NASA’s Orion Manager of Production Operations at KSC, told Universe Today during an interview at the KSC shuttle landing facility while the offloading was in progress.

“It will be installed onto the bottom of the Orion crew module in March 2014.”

The inaugural flight of Orion on the unmanned Exploration Flight Test – 1 (EFT-1) mission is scheduled to blast off from the Florida Space Coast in mid September 2014 atop a Delta 4 Heavy booster, Wilson told me.

The heat shield was flown in from Textron Defense Systems located near Boston, Massachusetts and offloaded from the Super Guppy on Dec. 5 as Universe Today observed the proceedings along with top managers from NASA and Orion’s prime contractor Lockheed Martin.

“The Orion heat shield is the largest of its kind ever built. Its wider than the Apollo and Mars Science Laboratory heat shields,” Todd Sullivan told Universe Today at KSC. Sullivan is the heat shield senior manager at Lockheed Martin.

The state-of-the-art Orion crew capsule will ultimately enable astronauts to fly to deep space destinations including the Moon, Asteroids, Mars and beyond – throughout our solar system.

The heat shield was one of the last major pieces of hardware needed to complete Orion’s exterior structure.

“Production of the heat shields primary structure that carries all the loads began at Lockheed Martin’s Waterton Facility near Denver,” said Sullivan. The titanium composite skeleton and carbon fiber skin were manufactured there to give the heat shield its shape and provide structural support during landing.

“It was then shipped to Textron in Boston in March,” for the next stage of assembly operations, Sullivan told me.

“They applied the Avcoat ablater material to the outside. That’s what protects the spacecraft from the heat of reentry.”

Textron technicians just completed the final work of installing a fiberglass-phenolic honeycomb structure onto the heat shield skin. Then they filled each of the honeycomb’s 320,000 cells with the ablative material Avcoat.

Each cell was X-rayed and sanded to match Orion’s exacting design specifications.

“Now we have about two and a half months of work ahead to prepare the Orion crew module before the heat shield is bolted on and installed,” Sullivan explained.

The Avcoat-treated shell will shield Orion from the extreme heat of nearly 4000 degrees Fahrenheit it experiences during the blazing hot temperatures it experiences as it returns at high speed to Earth. The ablative material will wear away as it heats up during the capsules atmospheric re-entry thereby preventing heat from being transferred to the rest of the capsule and saving it and the human crew from utter destruction.

“Testing the heat shield is one of the prime objectives of the EFT-1 flight,” Wilson explained.

“The Orion EFT-1 capsule will return at over 20,000 MPH,” Wilson told me. “That’s about 80% of the reentry speed experienced by the Apollo capsule after returning from the Apollo moon landing missions.”

“The big reason to get to those high speeds during EFT-1 is to be able to test out the thermal protection system, and the heat shield is the biggest part of that.”

The two-orbit, four- hour EFT-1 flight will lift the Orion spacecraft and its attached second stage to an orbital altitude of 3,600 miles, about 15 times higher than the International Space Station (ISS) – and farther than any human spacecraft has journeyed in 40 years.

“Numerous sensors and instrumentation have been specially installed on the EFT-1 heat shield and the back shell tiles to collect measurements of things like temperatures, pressures and stresses during the extreme conditions of atmospheric reentry,” Wilson explained.

The data gathered during the unmanned EFT-1 flight will aid in confirming. or refuting, design decisions and computer models as the program moves forward to the first flight atop NASA’s mammoth SLS booster in 2017 on the EM-1 mission and human crewed missions thereafter.

“I’m very proud of the work we’ve done, excited to have the heat shield here [at KSC] and anxious to get it installed,” Sullivan concluded.

China’s Maiden Moon Rover Mission Chang’e 3 Achieves Lunar Orbit

China’s maiden moon landing probe successfully entered lunar orbit on Friday, Dec. 6, following Sunday’s (Dec. 1) spectacular blastoff – setting the stage for the historic touchdown attempt in mid December.

Engineer’s at the Beijing Aerospace Control Center (BACC) commanded the Chang’e 3 lunar probe to fire its braking thrusters for 361 seconds, according to China’s Xinhua news agency.

The do or die orbital insertion maneuver proceeded precisely as planned at the conclusion of a four and a half day voyage to Earth’s nearest neighbor.

China’s ‘Yutu’ lunar lander is riding piggyback atop the four legged landing probe during the history making journey from the Earth to the Moon.

The critical engine burn placed Chang’e 3 into its desired 100 kilometer (60 mi.) high circular orbit above the Moon’s surface at 5:53 p.m. Friday, Beijing Time (4:53 a.m. EST).

An engine failure would have doomed the mission.

Chang’e 3 is due to make a powered descent to the Moon’s surface on Dec. 14, firing the landing thrusters at an altitude of 15 km (9 mi) for a soft landing in a preselected area called the Bay of Rainbows or Sinus Iridum region.

The Bay of Rainbows is a lava filled crater located in the upper left portion of the moon as seen from Earth. It is 249 km in diameter.

The variable thrust engine can continuously vary its thrust power between 1,500 to 7,500 newtons, according to Xinhua.

The lander is equipped with terrain recognition equipment and software to avoid rock and boulder fields that could spell catastrophe in the final seconds before touchdown if vehicle were to land directly on top of them.

The voyage began with the flawless launch of Chang’e 3 atop China’s Long March 3-B booster at 1:30 a.m. Beijing local time, Dec. 2, 2013 (12:30 p.m. EST, Dec. 1) from the Xichang Satellite Launch Center, in southwest China.

If successful, the Chang’e 3 mission will mark the first soft landing on the Moon since the Soviet Union’s unmanned Luna 24 sample return vehicle landed nearly four decades ago back in 1976.

Chang’e 3 targeted lunar landing site in the Bay of Rainbows or Sinus Iridum

The name for the ‘Yutu’ rover – which means ‘Jade Rabbit’ – was chosen after a special naming contest involving a worldwide poll and voting to select the best name.

‘Yutu’ stems from a Chinese fairy tale, in which the goddess Chang’e flew off to the moon taking her little pet Jade rabbit with her.

The six-wheeled ‘Yutu’ rover will be lowered in stages to the moon’s surface in a complex operation and then drive off a pair of landing ramps to explore the moon’s terrain.

Yutu measures 150 centimeters high and weighs approximately 120 kilograms.

The rover and lander are equipped with multiple cameras, spectrometers, an optical telescope, radar and other sensors to investigate the lunar surface and composition.

Chang’e 3 marks the beginning of the second phase of China’s lunar robotic exploration program.

The lander follows a pair of highly successful lunar orbiters named Chang’e 1 and 2 which launched in 2007 and 2010.

The next step will be an unmanned lunar sample return mission, perhaps by 2020.

China’s Chang’e 3 probe joins NASA’s newly arrived LADEE lunar probe which entered lunar orbit on Oct. 6 following a similarly spectacular night time blastoff from NASA’s Wallops Flight Facility in Virginia.

Speedy Particles Whip At Nearly The Speed Of Light In Earth’s Radiation Belts

The radiation-heavy Van Allen Belts around Earth contain particles that can move at almost the speed of light across vast distances, new research reveals. The information came from an instrument flown aboard the Van Allen Probes twin NASA spacecraft, which launched in 2012.

According to scientists, the process that creates this is similar to what happens in the Large Hadron Collider and other particle accelerators. The magnetic field on the Earth accelerates electrons faster as these particles orbit the planet. While scientists had spotted this process happening at small scales before, the new paper has seen this across hundreds of thousands of kilometers or miles.

“With the Van Allen Probes, I like to think there’s no place for these particles to hide because each spacecraft is spinning and ‘glimpses’ the entire sky with its detector ‘eyes’, so we’re essentially getting a 360-degree view in terms of direction, position, energy, and time,” stated Harlan Spence, principal scientist for the Energetic Particle, Composition, and Thermal Plasma (ECT) instrument aboard the probes, and co-author on the research paper. He is also director of the University of New Hampshire Institute for the Study of Earth, Oceans, and Space.

The research was led by University of Alberta physicist Ian Mann, and is available in Nature Communications. “People have considered that this acceleration process might be present but we haven’t been able to see it clearly until the Van Allen Probes,” Mann stated.

This Time-Lapse ISS Video Isn’t Just Another Time-Lapse ISS Video

It’s actually remarkably beautiful, and well worth two minutes of your time.*

Assembled from actual photographs taken by astronauts aboard the Space Station, many of them by Don Pettit during Expedition 31 (Don took a lot of photos) this timelapse “The World Outside My Window” by David Peterson ramps up the artistic value by featuring super-duper high definition, smoothed frame transitions and a musical score by “Two Steps From Hell.” (Don’t worry, that sounds scarier than it is.) Even if you’ve seen some of these clips before, they’re worth another go.

After all, there’s no good reason not to be reminded of how beautiful our planet is from space. Enjoy!

*It’s actually two minutes and twenty-eight seconds but I don’t think you’ll mind.

Awesome ‘Sideways’ View from Space of the Erupting Kliuchevskoi Volcano

We’ve seen some great views from space of erupting volcanoes, like Pavlov, Shiveluch, and Nabro. While most of the views from space look straight down in a in a nadir view, this photo was taken from the International Space Station with an oblique or sideways viewing angle. This provides a three-dimensional-type view, similar to what might be seen from an airplane instead of a flattened view that looks straight down. This image was taken by an astronaut when the ISS was located over a ground position more than 1,500 kilometers (900 miles) to the southwest of the Kamchatka Peninsula in the far eastern part of Russia. The Kliuchevskoi volcano is just one of 160 volcanoes in this region, with 29 of the 160 being active.

NASA says the plume—likely a combination of steam, volcanic gases, and ash—stretched to the east-southeast due to prevailing winds. The dark region to the north-northwest is likely a product of shadows and of ash settling out. Several other volcanoes are visible in the image, including Ushkovsky, Tolbachik, Zimina, and Udina. To the south-southwest of Kliuchevskoi lies Bezymianny Volcano, which appears to be emitting a small steam plume (at image center).

These volcanic peaks are an eye-catching landmark from orbit. Here’s an image of the same region taken by astronaut Chris Hadfield earlier this year:

CAPE CANAVERAL, FL – China successfully launched its first ever lunar rover bound for the Moon’s surface aboard a Long March rocket today at 1:30 a.m. Beijing local time, Dec. 2, 2013 (12:30 p.m. EST, Dec. 1) from the Xichang Satellite Launch Center in southwest China.

The spectacular night time blastoff of the Long March-3B carrier rocket with the ‘Yutu’ rover was carried live on China’s state run CCTV enabling viewers worldwide to watch the dramatic proceedings as they occurred in real time – including fantastic imagery of booster jettison, spacecraft separation, thruster firings and exquisite views of Earth from cameras aboard the booster.

See the stunning launch video below.

The entire flight sequence proceeded flawlessly and placed the combined Chang’e 3 lunar landing vehicle and ‘Yutu’ rover on the desired earth-moon transfer orbit following spacecraft separation and unfurling of the life giving solar panels and landing legs, announced Zhang Zhenzhong, director of the Xichang center.

“The Chang’e probe is on its way to the moon, of course, is a symbol of China’s national prowess,” said Zhang Zhenzhong through a translator during the live CCTV broadcast. “Of course, it’s a symbol of China’s national power and prowess.”

The three stage 55 meter (185 foot) tall Long March-3B carrier rocket was uniquely equipped with a quartet of strap on liquid fueled boosters to provide the additional liftoff thrust required for the four day journey to Earth’s Moon.

The name for the ‘Yutu’ rover – which translates as ‘Jade Rabbit’ – was chosen after a special naming contest involving a worldwide poll and voting to select the best name.

‘Yutu’ stems from a Chinese fairy tale, in which the goddess Chang’e flew off to the moon taking her little pet Jade rabbit with her.

The Chang’e 3 lander will fire thrusters to enter lunar orbit on Dec. 6.

It is due to make a powered descent to the lunar surface on Dec. 14, firing thrusters at an altitude of 15 km (9 mi) for touchdown in a preselected area called the Bay of Rainbows or Sinus Iridum region.

If successful, the Chang’e 3 mission will mark the first soft landing on the Moon since the Soviet Union’s unmanned Luna 24 sample return vehicle landed nearly four decades ago back in 1976.

‘Yutu’ is sitting atop the 4 legged landing probe during the launch and voyage to the Moon.

A complex maneuver will be used to deploy the six-wheeled ‘Jade Rabbit’ rover. It will be lowered in stages to the moon’s surface and then drive off a pair of landing ramps to explore the moon’s terrain.

Watch this short CCTV news report with a cool animation showing how the ‘Yutu’ rover reaches the lunar surface.

‘Jade Rabbit’ measures 150 centimeters high and weighs approximately 120 kilograms.

The rover and lander are equipped with multiple cameras, spectrometers, an optical telescope, radar and other sensors to investigate the lunar surface and composition.

One highly anticipated highlight will be when the lander and deployed Jade Rabbit rover image each other on the surface.

The rover is expected to continue operating for at least three months.

The Chang’e 3 landing mission marks the beginning of the second phase of China’s lunar robotic exploration program.

It follows a pair of highly successful lunar orbiters named Chang’e 1 and 2 which launched in 2007 and 2010.

The next step will be an unmanned lunar sample return mission, perhaps around 2020.
