UPDATE: NASA Pushes Back Cygnus Launch Decision Due To Space Station Cooling Problem

The decision to launch a cargo flight to the International Space Station next week has been pushed back until Monday (Dec. 16) because of a cooling problem on station that forced the shutdown of redundant systems, according to a NASA update.

Orbital Sciences’ Cygnus commercial spacecraft is expected to blast off on Dec. 18 from the Wallops Flight Facility in Virginia. However, with some station systems offline, the launch does not now meet certain “commit criteria” to make its journey to space next week, said Kenny Todd, the space station’s mission integration and operations manager.

“We haven’t lost any primary functionality,” he said in a NASA Television update today (Dec. 12), emphasizing that the six-person Expedition 38 crew is fine. “There is some redundancy that we’re down right now, but that’s not something I would call critical to day-to-day station operations.”

While a spacewalk is a possibility to fix the problem, it’s too early to say what NASA and other space station partners will decide to do.

NASA controllers spent the night examining a control valve blamed for causing an ammonia pump to shut down yesterday (Dec. 12). The space station uses liquid ammonia to maintain its temperature, pumping the ammonia through external radiators to bleed off heat. Astronauts have made periodic spacewalks to repair parts of the ammonia system, most recently in May when Expedition 35 replaced a pump controller box on the P6 (far port) truss just days before some crew members went home.

“The pump module on one of ISS two external cooling loops automatically shut down today when it got too cold,” stated the NASA Johnson Space Center Twitter feed yesterday (Dec. 11).

“The pump was brought back online, but they think a valve may not be working correctly inside it. Some of the station’s internal electrical systems were moved over to the second loop, and some noncritical things were powered down. The crew was always safe and will work with the ground teams as they figure out what caused the issue.”

Non-critical systems were powered down in the Harmony node, Columbus Laboratory and Japanese Kibo laboratory. After confirming that the new configuration was stable, controllers began this morning (EST) to move the troublesome valve to several positions and monitor the effect on cooling temperatures, according to a NASA TV update.

The crew is going about their activities as much as possible, although they’re on a “reduced timeline” because some of the experiments aren’t running as usual. (Science collected up to now is “not at risk”, Todd said.)

Responding to questions on social media, NASA astronaut Douglas Wheelock — who led three unplanned spacewalks in 2010 to replace a broken ammonia pump module on the S1 truss in the same cooling loop — said he is working with Mission Control to see what needs to be done next.

Of note, NASA has suspended spacewalks after a water leak in one of its spacesuits forced Italian astronaut Luca Parmitano back to the airlock during work in July. (Crewmate Chris Cassidy, who was on the spacewalk at the same time, later said he felt Parmitano was in no immediate danger, but felt the prudent thing to do was stop.)

Astronauts have been troubleshooting the suit periodically on board station, but NASA is planning to send it back on the next SpaceX Dragon flight to Earth for further investigation. SpaceX isn’t planning to get to the station again until late February, media reports say. Russian spacewalks can still continue as they use a separate suit; the most recent one took place in November with the Olympic torch.

While Todd didn’t quite say the ban on spacewalks has been lifted, he added that NASA has new procedures in place to guard against another crew member facing the same water issue. He did not elaborate on what those procedures are.

The current launch window for Cygnus extends as far as Dec. 21 and “possibly” the 22nd, Todd said, but emphasized more time is needed to come to a decision. “At this point, for lack of a better term, we’re going to kick the can a little bit and let the team work a little bit more,” he said.

Updates will follow as the situation and fix progresses.

Mars One Proposes First Privately Funded Robotic Mars Missions – 2018 Lander & Orbiter

The Mars One non-profit foundation that aims to establish a permanent human settlement on the Red Planet in the mid-2020’s – with colonists volunteering for a one-way trip – took a major step forward today, Dec. 10, when they announced plans to launch the first ever privately funded space missions to Mars in 2018; as forerunners to gather critical measurements.

Bas Lansdorp, Mars One Co-founder and CEO announced plans to launch two missions to the Red Planet in 2018 – consisting of a robotic lander and an orbiting communications satellite; essential for transmitting the data collected on the Red Planet’s surface.

And he has partnered with a pair of prestigious space companies to get started.

Lansdorp made the announcement at a news media briefing held today at the National Press Club in Washington, DC.

“This will be the first private mission to Mars and the lander’s successful arrival and operation will be a historic accomplishment,” said Lansdorp.

Lansdorp stated that Mars One has signed contracts with Lockheed Martin and Surrey Satellite Technology Ltd. (SSTL) to develop mission concept studies – both are leading aerospace companies with vast experience in building spacecraft.

The 2018 Mars One lander would be a technology demonstrator and include a scoop, cameras and an exotic solar array to boost power and longevity.

The spacecraft structure would be based on NASA’s highly successful 2007 Phoenix Mars lander – built by Lockheed Martin – which discovered and dug into water ice buried just inches beneath the topsoil in the northern polar regions of the Red Planet.

“We are excited to have been selected by Mars One for this ambitious project and we’re already working on the mission concept study, starting with the proven design of Phoenix,” said Ed Sedivy, Civil Space chief engineer at Lockheed Martin Space Systems. “Having managed the Phoenix spacecraft development, I can tell you, landing on Mars is challenging and a thrill and this is going to be a very exciting mission.”

Lockheed Martin engineers will work for the next 3 to 4 months to study mission concepts as well as how to stack the orbiter and lander on the launcher,” Sedivy said at the briefing.

“The lander will provide proof of concept for some of the technologies that are important for a permanent human settlement on Mars,” said Lansdorp.

Two examples involve experiments to extract water into a usable form and construction of a thin film solar array to provide additional power to the spacecraft and eventual human colonists.

It would include a Phoenix like scoop to collect soils for the water extraction experiment and cameras for continuous video recording transmitted by the accompanying orbiter.

Lockheed Martin is already under contract to build another Phoenix type lander for NASA that is slated to blastoff in 2016 on the InSight mission.

“They have a distinct legacy of participating in nearly every NASA mission to Mars,” said Lansdorp.

So if sufficient funding is found it seems apparent that lander construction should be accomplished in time.

However, building the science instruments from scratch to meet the tight timeline could be quite challenging.

Given that the lander is planned to launch in barely over four years, I asked Sedivy if that was sufficient time to select, design and develop the new science instruments planned for the 2018 mission.

“A typical life cycle for the Mars program provides three and a half years from commitment to design to launch. So we have about 1 year to commit to preliminary design for the 2018 launch, so that’s favorable,” Sedivy told Universe Today.

“Now as for having enough time for selecting the suite of science experiments that’s a little trickier. It depends on what’s actually selected and the maturity of those elements selected.”

“So we will provide Mars One with input as to where we see the development risks. And we’ll help guide the instrument selections to have a high probability that they will be ready in time for the 2018 launch window,” Sedivy told me.

For the 2018 lander, Mars One also plans to include an experiment from a worldwide university challenge and items from several Science, Technology, Engineering and Math (STEM) challenge winners.

Surrey Satellite Technology Ltd. (SSTL) was selected to studying orbiter concepts that will provide a high bandwidth communications system in a Mars synchronous orbit and will be used to relay data and a live video feed from the lander on the surface of Mars back to Earth, according to Sir Martin Sweeting, Executive Chairman of SSTL.

There are still many unknowns at this stage including the sources for all the significant funding required by Mars One to transform their concepts into actual flight hardware.

“Crowdfunding and crowdsourcing activities are important means to do that,” said Lansdorp.

At the briefing, Lansdorp stated that Mars One has started an Indiegogo crowdfunding campaign. The goal is to raise $400,000 by Jan. 25, 2014.

Link to – Indiegogo Mars One campaign

Mars One is looking for sponsors and partners. They also plan a TV show to help select the winners of the first human crew to Mars from over 200,000 applicants from countries spread all across Earth.

The preliminary 2018 mission study contracts with Lockheed and Surrey are valued at $260,000 and $80,000 respectively.

How Much Radiation Would You Get During A Mars Mission?

While asking questions about habitability on Mars, one thing that scientists also need to consider is whether it’s safe enough for humans to even do exploration there. Radiation is definitely a big factor — in a press conference yesterday (Dec. 9) for the American Geophysical Union’s conference, scientists said the environment is unlike anything we are used to naturally on Earth.

Radiation on Mars comes from two sources: galactic cosmic rays (over the long term) and solar energetic particles (in short bursts of activity when the sun gets super-active). Of note, the sun has had a muted peak to its solar cycle, so that’s affecting the expected amount of particles on Mars. But the Mars Curiosity rover, in its first 300 Earth days of roaming, has plenty of data on galactic cosmic rays.

On the Martian surface, the average dose is about 0.67 millisieverts (mSv) per day, at least between the measurement period of August 2012 and June 2013. The journey to Mars had a dose of 1.8 mSv per day inside the spaceship. So what does that means for NASA’s human health consideration concerns?

With a 500-day trip on the surface and the journey to and from Mars (which would take 180 days each way), NASA is saying the total dosage for the mission would be about 1 Sv. Population studies over the long term have shown that increases the fatal cancer risk by 5%. Current NASA guidelines for low-Earth orbit don’t allow for a more than 3% increase, but 1 Sv is within the guidelines for several other space agencies.

But don’t rule out the trip to Mars yet, NASA states: “[NASA] does not currently have a limit for deep space missions, and is working with the National Academies Institute of Medicine to determine appropriate limits for deep space missions, such as a mission to Mars in the 2030s.”

Besides, other entities are thinking about going, such as Mars One.

Read more about the radiation findings in this Dec. 9 article on Science. The research was led by Don Hassler, a Southwest Research Institute program director and principal investigator of Curiosity’s radiation assessment detector (RAD).

Curiosity Discovers Ancient Mars Lake Could Support Life

Outcrops in Yellowknife Bay are being exposed by wind driven erosion. These rocks record superimposed ancient lake and stream deposits that offered past environmental conditions favorable for microbial life.

NASA’s Curiosity rover has discovered evidence that an ancient Martian lake had the right chemical ingredients that could have sustained microbial life forms for long periods of time – and that these habitable conditions persisted on the Red Planet until a more recent epoch than previously thought.

Furthermore researchers have developed a novel technique allowing Curiosity to accurately date Martian rocks for the first time ever – rather than having to rely on educated guesses based on counting craters.

All that and more stems from science results just announced by members of the rover science team.

Researchers outlined their remarkable findings in a series of six new scientific papers published today (Dec. 9) in the highly respected journal Science and at talks held today at the Fall 2013 Annual Meeting of the American Geophysical Union (AGU) in San Francisco.

The Curiosity team also revealed that an investigation of natural Martian erosion processes could be used to direct the rover to spots with a higher likelihood of holding preserved evidence for the building blocks of past life – if it ever existed.

The ancient fresh water lake at the Yellowknife Bay area inside the Gale Crater landing site explored earlier this year by Curiosity existed for periods spanning perhaps millions to tens of millions of years in length – before eventually evaporating completely after Mars lost its thick atmosphere.

Furthermore the lake may have existed until as recently as 3.7 Billion years ago, much later than researchers expected which means that life had a longer and better chance of gaining a foothold on the Red Planet before it was transformed into its current cold, arid state.

Researchers also announced that they are shifting the missions focus from searching for habitable environments to searching for organic molecules – the building blocks of all life as we know it.

Why the shift? Because the team believes they have found a way to increase the chance of finding organics preserved in the sedimentary rock layers.

“Really what we’re doing is turning the corner from a mission that is dedicated to the search for habitable environments to a mission that is now dedicated to the search for that subset of habitable environments which also preserves organic carbon,” Curiosity Principal Investigator John Grotzinger, of the California Institute of Technology in Pasadena, said at an AGU press conference today.

“That’s the step we need to take as we explore for evidence of life on Mars.”

Earlier this year, Curiosity drilled into a pair of sedimentary Martian mudstone rock outcrops at Yellowknife Bay known as “John Klein” and “Cumberland” – for the first time in history.

Grotzinger said the ancient lake at Yellowknife Bay was likely about 30 miles long and 3 miles wide.

Powdered samples deposited into the rovers miniaturized chemistry labs – SAM and CheMin – revealed the presence of significant levels of phyllosilicate clay minerals.

These clay minerals form in neutral pH water that is ‘drinkable” and conducive to the formation of life.

“Curiosity discovered that the fine-grained sedimentary rocks preserve evidence of an environment that would have been suited to support a Martian biosphere founded on chemolithoautotrophy,” according to one of the science papers co-authored by Grotzinger.

“This aqueous environment was characterized by neutral pH, low salinity, and variable redox states of both iron and sulfur species.”

The rover has detected key elements required for life including carbon, hydrogen, oxygen, sulfur nitrogen and phosphorous.

The team is still looking for signatures of organic molecules.

Right now the researchers are driving Curiosity along a 6 mile path to the base of Mount Sharp -the primary mission destination – which they hope to reach sometime in Spring 2014.

But along the way they hope to stop at a spot where wind has eroded the sedimentary rocks just recently enough to expose an area that may still preserve evidence for organic molecules – since it hasn’t been bombarded by destructive cosmic radiation for billions of years.

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.

CAPE CANAVERAL AIR FORCE STATION, FL – The flawless blastoff of SpaceX’s next generation Falcon 9 rocket on Tuesday Dec. 3 put on a spectacular sky show along the Florida Space Coast that was both beautiful and unforgettable – besides being truly historic as the firms first ever delivery of a commercial space satellite to the lucrative market of geostationary orbit.

For your enjoyment here’s a collection of photos and videos from fellow space photojournalists of the 5:41 p.m. EST sunset launch from Space Launch Complex 40 (SLC-40) at Cape Canaveral Air Force Station, FL.

Following a pair of launch scrubs last week on Nov. 25 and Thanksgiving Day Nov. 28 caused by issues with the powerful new Merlin 1-D first stage engines, the third time was fat last the charm as the Falcon 9 blasted precisely at the opening of the 86 minute launch window.

CAPE CANAVERAL AIR FORCE STATION, FL – SpaceX scored a spectacular launch success this evening (Dec. 3 ) when the maiden flight of their upgraded Falcon 9 rocket from Florida scorched the sky of the Florida Space Coast and successfully delivered a commercial space satellite to geostationary orbit for the first time ever – thereby revolutionizing the commercial space industry from this day forward.

The third time was finally the charm as the Falcon 9 blasted off precisely on time at 5:41 p.m. EST from Launch Complex 40 at Cape Canaveral following a pair of launch scrubs last week on Nov. 25 and Thanksgiving Day Nov. 28 caused by technical problems with the first stage engine.

The booster thundered off the pad and pierced the completely cloud free evening sky soon after sunset as the blistering roar rumbled deafeningly all across the space coast viewing area.

The rocket exhaust plume was easily visible for several minutes after liftoff of the historic mission.

The 3,138 kg (6,918 lbs) SES-8 satellite was built by Orbital Sciences for SES and is a hybrid Ku- and Ka-band spacecraft that will provide TV and communications coverage for the South Asia and Asia Pacific regions.

This new version of the Falcon 9 rocket has nearly 50% more thrust compared to the original Falcon 9.

The stakes could not have been higher for the future of SpaceX.

The firms future launch manifest of more than 50 flights for NASA and a variety of commercial entities worth billions of dollars were riding on the success of tonight’s liftoff from Cape Canaveral Air Force Station, Florida.

With 54 satellites in orbit SES is one of the largest commercial telecommunications satellite operators in the world.

The next generation Falcon 9 rocket injected the SES-8 telecommunications to its targeted geostationary transfer orbit flying 295 x 80,000 km above Earth.

A restart of the second stage engine was absolutely essential to the success of the mission since a failure to ignite would have doomed the SES-8 satellite from reaching is desired orbit since it’s a requirement for all geostationary transfer missions.

The picture-perfect flight met 100% of the mission objectives, SpaceX said in a post-launch statement.

“The successful insertion of the SES-8 satellite confirms the upgraded Falcon 9 launch vehicle delivers to the industry’s highest performance standards,” said Elon Musk, CEO and Chief Designer of SpaceX.

“As always, SpaceX remains committed to delivering the safest, most reliable launch vehicles on the market today. We appreciate SES’s early confidence in SpaceX and look forward to launching additional SES satellites in the years to come.”

Today’s launch marked SpaceX’s first commercial launch from Florida as well as the first commercial flight from Cape Canaveral Air Force Station in over five years.

Satellite operators have booked their commercial launches with other rocket companies overseas due to the high cost of other American expendable rockets.

SpaceX’s entire corporate aim has been to significantly cut the high cost of access to space.

“This is really rocking the industry. Everybody has to look out,” said Martin Halliwell, SES chief technical officer, at the prelaunch meeting with reporters including Universe Today.

With today’s SpaceX is sure to sign even more contracts bringing additional commercial telecommunications satellite space launches back to American soil.

Approximately 185 seconds into flight, the Falcon 9’s second stage equipped with a single Merlin 1-D engine ignited.

It burned for five minutes and 20 seconds to inject SES-8 satellite into its initial parking orbit.

Eighteen minutes later the second stage engine relit for a second time and fired for just over one minute to deliver SES-8 satellite to its final geostationary transfer orbit.

This extra powerful new version of the Falcon 9 dubbed v1.1 is powered by a cluster of nine of SpaceX’s new Merlin 1D engines that are about 50% more powerful compared to the standard Merlin 1C engines. The nine Merlin 1D engines 1.3 million pounds of thrust at sea level rises to 1.5 million pounds as the rocket climbs to orbit.

The Merlin 1 D engines are arrayed in an octaweb layout for improved efficiency.

Therefore the upgraded Falcon 9 can boost a much heavier cargo load to the ISS, low Earth orbit, geostationary orbit and beyond.

The next generation Falcon 9 is a monster. It measures 224 feet tall and is 12 feet in diameter. That compares to a 130 foot tall rocket for the original Falcon 9.

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.

CAPE CANAVERAL, FL – Today (Dec. 3) marks the 3rd attempt by SpaceX to launch the maiden flight of their significantly upgraded Falcon 9 rocket with the SES-8 telecommunications satellite – following the Nov. 28 ‘Thanksgiving = Spacegiving Day’ scrub due to an aborted 1st stage engine firing in progress.

And the stakes could not be higher for the future of SpaceX – with the firms future launch manifest worth billions of dollars riding on the success of today’s liftoff from Cape Canaveral Air Force Station, Florida.

In an unprecedented launch event for SpaceX, the upper stage engine on the next generation Falcon 9 booster absolutely must restart in flight for a second time in order for the commercial SES-8 payload to be delivered to geostationary transfer orbit (GTO).

Blastoff from Cape Canaveral’s seaside Space Launch Complex 40 is set for 5:41 p.m. EST (2241 GMT).

The Thanksgiving Day launch was aborted by the computers when the Marlin engines thrust failed to build up as fast as planned.

The weather forecast currently shows a 90% chance of favorable conditions at liftoff time according to Air Force meteorologists. The only concern is for winds.

The launch of SES-8 is a milestone marking the first ever attempt by SpaceX to place a satellite into the geostationary orbit replete with numerous high value commercial satellites. This is the doorway to the future profitability of SpaceX.

“I don’t want to tempt fate, but I think it’s going to have a pretty significant impact on the world launch market and on the launch industry because our prices are the most competitive of any in the world,” said SpaceX CEO and chief designer Elon Musk at a prelaunch briefing for media including Universe Today in Cocoa Beach, FL.

For the mission to be declared a success, the upper stage engine must reignite precisely as planned about 27 minutes after liftoff and burn for approximately 1 minute to successfully propel SES-8 into the propel orbit about 33 minutes after launch.

“Whether or not this launch is successful, I’m confident we will certainly make it on some subsequent launch,” said Musk.

“This is really rocking the industry. Everybody has to look out,” said Martin Halliwell, SES chief technical officer, who joined Musk at the prelaunch meeting.

The upgraded Falcon 9 will also be the launcher utilized for the manned SpaceX Dragon capsules launching to the ISS sometime later this decade!

And the very next satellite set for launch by SpaceX later in December – Thaicom 6- is essentially already waiting at the door to the onramp to space.

SpaceX plans a live broadcast of the Falcon 9 liftoff from pad 40 on Cape Canaveral Air Force Station, FL beginning at 5 p.m. EST.

It can be viewed here: www.spacex.com/webcast

The show will feature commentary about the Falcon 9 rocket and launch sequences and the SES-8 commercial satellite from SpaceX corporate headquarters in Hawthorne, CA.

The Falcon 9/SES-8 launch window extends for 86 minutes until 7:07 p.m. EST.

The 3,138 kg (6,918 lbs) SES-8 satellite is a hybrid Ku- and Ka-band spacecraft that will provide TV and communications coverage for the South Asia and Asia Pacific regions.

This mighty new version of the Falcon 9 dubbed v1.1 is powered by a cluster of nine of SpaceX’s new Merlin 1D engines that are about 50% more powerful compared to the standard Merlin 1C engines.
