While the Great Wall of China is not readily visible from space (we debunked that popular myth here) there are several other human-built structures that actually can be seen from space. And that list is growing, thanks to the large solar farms being built around the world.
The solar farm with the current distinction of being the largest in the world — as of February 2017 – is the Longyangxia Dam Solar Park in China. These new images from NASA’s Landsat 8 satellite show the farm’s blue solar panels prominently standing out on the brown landscape of the western province of Qinghai, China. Reportedly, the solar farm covers 27 square kilometers (10.42 square miles), and consists of nearly 4 million solar panels.
You can see in the image below from 2013 that the farm has been growing over the years. The project has cost the amount of 6 billion yuan ($889.5 million).

China wants to shed its title of the biggest polluter in the world and is now investing in clean, renewable energy. It has a goal of producing 110 GW of solar power and 210 GW of wind power by the year 2020. That sounds like a lot, but in a country of 1.4 billion people that relies heavily on coal, it amounts to less than 1 percent of the country’s more than 1,500 gigawatts of total power generation capacity, says Inside Climate News.
According to NASA, China is now the world’s largest producer of solar power, however Germany, Japan, and the United States produce more solar power per person.
China has another solar farm in the works that will have a capacity of 2,000 MW when it is finished.

Whether or not a planet has a magnetic field goes a long way towards determining whether or not it is habitable. Whereas Earth has a strong magnetosphere that protects life from harmful radiation and keeps solar wind from stripping away its atmosphere, planet’s like Mars no longer do. Hence why it went from being a world with a thicker atmosphere and liquid water on its surface to the cold, desiccated place it is today.
For this reason, scientists have long sought to understand what powers Earth’s magnetic field. Until now, the consensus has been that it was the dynamo effect created by Earth’s liquid outer core spinning in the opposite direction of Earth’s rotation. However, new research from the Tokyo Institute of Technology suggests that it may actually be due to the presence of crystallization in the Earth’s core.
The research was conducted by scientists from the Earth-Life Science Institute (ELSI) at Tokyo Tech. According to their study – titled “Crystallization of Silicon Dioxide and Compositional Evolution of the Earth’s Core“, which appeared recently in Nature – the energy that drives the Earth’s magnetic field may have more to do with the chemical composition of the Earth’s core.

Of particular concern for the research team was the rate of which Earth’s core cools over geological time – which has been the subject of debate for some time. And for Dr. Kei Hirose – the director of the Earth-Life Science Institute and lead author on the paper – it has been something of a lifelong pursuit. In a 2013 study, he shared research findings that indicated how the Earth’s core may have cooled more significantly than previously thought.
He and his team concluded that since the Earth’s formation (4.5 billion years ago), the core may have cooled by as much as 1,000 °C (1,832 °F). These findings were rather surprising to the Earth sciences community – leading to what one scientists referred to as the “New Core Heat Paradox“. In short, this rate of core cooling would mean that some other source of energy would be required to sustain the Earth’s geomagnetic field.
On top of this, and related to the issue of core-cooling, were some unresolved questions about the chemical composition of the core. As Dr. Kei Hirose said in a Tokyo Tech press release:
“The core is mostly iron and some nickel, but also contains about 10% of light alloys such as silicon, oxygen, sulfur, carbon, hydrogen, and other compounds. We think that many alloys are simultaneously present, but we don’t know the proportion of each candidate element.”

In order to resolve this, Hirose and his colleagues at ELSI conducted a series of experiments where various alloys were subjected to heat and pressure conditions similar to that in the Earth’s interior. This consisted of using a diamond anvil to squeeze dust-sized alloy samples to simulate high pressure conditions, and then heating them with a laser beam until they reached extreme temperatures.
In the past, research into iron alloys in the core have focused predominantly on either iron-silicon alloys or iron-oxide at high pressures. But for the sake of their experiments, Hirose and his colleagues decided to focus on the combination of silicon and oxygen – which are believed to exist in the outer core – and examining the results with an electron microscope.
What the researchers found was that under conditions of extreme pressure and heat, samples of silicon and oxygen combined to form silicon dioxide crystals – which were similar in composition to mineral quartz found in the Earth’s crust. Ergo, the study showed that the crystallization of silicon dioxide in the outer core would have released enough buoyancy to power core convection and a dynamo effect from as early on as the Hadean eon onward.
As John Hernlund, also a member of ELSI and a co-author of the study, explained:
“This result proved important for understanding the energetics and evolution of the core. We were excited because our calculations showed that crystallization of silicon dioxide crystals from the core could provide an immense new energy source for powering the Earth’s magnetic field.”

This study not only provides evidence to help resolve the so-called “New Core Heat Paradox”, it also may help advance our understanding of what conditions were like during the formation of Earth and the early Solar System. Basically, if silicon and oxygen form crystal of silicon dioxide in the outer core over time, then sooner or later, the process will stop once the core runs out of these elements.
When that happens, we can expect Earth’s magnetic field will suffer, which will have drastic implications for life on Earth. It also helps to put constraints on the concentrations of silicon and oxygen that were present in the core when the Earth first formed, which could go a long way towards informing our theories about Solar System formation.
What’s more, this research may help geophysicists to determine how and when other planets (like Mars, Venus and Mercury) still had magnetic fields (and possibly lead to ideas of how they could be powered up again). It could even help exoplanet-hunting science teams determine which exoplanets have magnetospheres, which would allow us to find out which extra-solar worlds could be habitable.
One of the most worrisome aspects of Climate Change is the role played by positive feedback mechanisms. In addition to global temperatures rising because of increased carbon dioxide and greenhouse gas emissions, there is the added push created by deforestation, ocean acidification, and (most notably) the disappearance of the Arctic Polar Ice Cap.
However, according to a new study by a team of researchers from the School of Earth and Space Exploration at Arizona State University, it might be possible to refreeze parts of the Arctic ice sheet. Through a geoengineering technique that would rely on wind-powered pumps, they believe one of the largest positive feedback mechanisms on the planet can be neutralized.
Their study, titled “Arctic Ice Management“, appeared recently in Earth’s Future, an online journal published by the American Geophysical Union. As they indicate, the current rate at which Arctic ice is disappearing it quite disconcerting. Moreover, humanity is not likely to be able to combat rising global temperatures in the coming decades without the presence of the polar ice cap.

Of particular concern is the rate at which polar ice has been disappearing, which has been quite pronounced in recent decades. The rate of loss has been estimated at being between 3.5% and 4.1% per decade, with in an overall decrease of at least 15% since 1979 (when satellite measurements began). To make things worse, the rate at which ice is being lost is accelerating.
From a baseline of about 3% per decade between 1978-1999, the rate of loss since the 2000s has climbed considerably – to the point that the extent of sea-ice in 2016 was the second lowest ever recorded. As they state in their Introduction (and with the support of numerous sources), the problem is only likely to get worse between now and the mid-21st century:
“Global average temperatures have been observed to rise linearly with cumulative CO2 emissions and are predicted to continue to do so, resulting in temperature increases of perhaps 3°C or more by the end of the century. The Arctic region will continue to warm more rapidly than the global mean. Year-round reductions in Arctic sea ice are projected in virtually all scenarios, and a nearly ice-free (<106 km2 sea-ice extent for five consecutive years) Arctic Ocean is considered “likely” by 2050 in a business-as-usual scenario.”
One of the reasons the Arctic is warming faster than the rest of the planet has to do with strong ice-albedo feedback. Basically, fresh snow ice reflects up to 90% of sunlight while sea ice reflects sunlight with albedo up to 0.7, whereas open water (which has an albedo of close to 0.06) absorbs most sunlight. Ergo, as more ice melts, the more sunlight is absorbed, driving temperatures in the Arctic up further.

Credit: National Snow and Ice Data CenterTo address this concern, the research team – led by Steven J. Desch, a professor from the School of Earth and Space Exploration – considered how the melting is connected to seasonal fluctuations. Essentially, the Arctic sea ice is getting thinner over time because new ice (aka. “first-year ice”), which is created with every passing winter, is typically just 1 meter (3.28 ft) thick.
Ice that survives the summer in the Arctic is capable of growing and becoming “multiyear ice”, with a typical thickness of 2 to 4 meters (6.56 to 13.12 ft). But thanks to the current trend, where summers are getting progressively warmer, “first-year ice” has been succumbing to summer melts and fracturing before it can grow. Whereas multiyear ice comprised 50 to 60% of all ice in the Arctic Ocean in the 1980s, by 2010, it made up just 15%.
With this in mind, Desch and his colleagues considered a possible solution that would ensure that “first-year ice” would have a better chance of surviving the summer. By placing machines that would use wind power to generate pumps, they estimate that water could be brought to the surface over the course of an Arctic winter, when it would have the best chance of freezing.
Based on calculations of wind speed in the Arctic, they calculate that a wind turbine with 6-meter diameter blades would generate sufficient electricity so that a single pump could raise water to a height of 7 meters, and at a rate of 27 metric tons (29.76 US tons) per hour. The net effect of this would be thicker sheets of ice in the entire affected area, which would have a better chance of surviving the summer.

Over time, the negative feedback created by more ice would cause less sunlight to be absorbed by the Arctic ocean, thus leading to more cooling and more ice accumulation. This, they claim, could be done on a relatively modest budget of $500 billion per year for the entire Arctic, or $50 billion per year for 10% of the Arctic.
While this may sounds like a huge figure, they are quick to point out that the cast covering the entire Arctic with ice-creating pumps – which could save trillions in GDP and countless lives- is equivalent to just 0.64% of current world gross domestic product (GDP) of $78 trillion. For a country like the United States, it represents just 13% of the current federal budget ($3.8 trillion).
And while there are several aspects of this proposal that still need to be worked out (which Desch and his team fully acknowledge), the concept does appear to be theoretically sound. Not only does it take into account the way seasonal change and Climate Change are linked in the Arctic, it acknowledges how humanity is not likely to be be able to address Climate Change without resorting to geoengineering techniques.
And since Arctic ice is one of the most important things when it comes to regulating global temperatures, it makes perfect sense to start here.
This simplified map of the continents shows the new continent Zealandia in grey. Image: Mortimer et. al. 2017, GSA Today.
We tend to lump New Zealand and Australia together. They’re similar culturally and share the same geographical position, relative to North America and Europe, anyway. But according to a new paper published in the Geological Society of America Today, it looks like New Zealand and their neighbor New Caledonia are actually their own continent: ‘Zealandia.’
Continent means something different to geographers and geologists. To be considered a geological continent, like Zealandia, the area in question has to satisfy a few conditions:
the land in question has to be higher than the ocean floor
it has to include a broad range of siliceous igneous, metamorphic, and sedimentary rocks
it has to have thicker crust than the ocean floor that surrounds it
it has to have well-defined limits, and be large enough to be considered a continent
In Geology, the first three points are well-understood. But as the authors say in the introduction to their paper, “…the last point—how “major” a piece of continental crust has to be to be called a continent—is almost never discussed… .” Since the Earth has so many micro-continents and continental fragments, defining how large something has to be to be called a continent is challenging. But the researchers did their homework.
They noted that the term “Zealandia” has been used before to describe New Zealand and surrounding regions. But the boundaries were never fully explored. 94% of this new continent is submerged, which helps explain why it’s taken this long to be identified.
This map shows the spatial limits of Zealandia. Note the dotted red line that delineates continental crust from ocean crust. Zealandia is also bisected by a plate boundary between the Pacific Plate and the Australian Plate. Image: Mortimer et. al. 2017, GSA Today
Zealandia seemed to be a collection of broken pieces, but new data collected over the years has challenged that interpretation. Recent satellite data has given us new gravity and elevation maps of the seafloor. This data has shown that Zealandia is a unified region large as large as India.
“This is not a sudden discovery but a gradual realization; as recently as 10 years ago we would not have had the accumulated data or confidence in interpretation to write this paper.”
As the authors point out in their paper, it took a while to determine that Zealandia is a continent. There was no Eureka moment. “This is not a sudden discovery but a gradual realization; as recently as 10 years ago we would not have had the accumulated data or confidence in interpretation to write this paper.”
Besides satisfying our intellectual curiosity about our planet, the discovery is important for other reasons. A proper understanding of the plate structures and continental boundaries is important to other sciences, and may trigger further understandings that we can’t predict yet. It may also point to other areas of research.
Also, many treaties rely on the agreed upon delineation of maritime and continental boundaries, including rights to fish stocks and underground resources. While the recognition of Zealandia seems clear from a scientific standpoint, it remains to be seen if it will be accepted politically.

“My previous background still applies,” FAA spokesman Hank Price confirmed to Universe Today.
“The FAA is working closely with SpaceX to ensure the activity described in the application meets all applicable regulations for a launch license.”
“The FAA will continue to work with SpaceX to provide a license determination in a timely manner.”
Blastoff of the Falcon 9 from seaside pad 39A at NASA’s Kennedy Space Center in Florida is slated for 10:01 a.m. EST Saturday, Feb. 18.
NASA plans live coverage of the launch beginning at 8:30 a.m. on NASA Television and the agency’s website.
SpaceX currently has license applications pending with the FAA for both the NASA cargo launch and pad 39A. No commercial launch can take place without FAA approval.
No License, No Launch – that’s the bottom line!
Assuming the FAA grants a launch license at the last minute on Friday the weather outlook currently is iffy for Saturday with a 60% chance of favorable conditions at launch time. The concerns are for rains and clouds according to Air Force weather forecasters.
In case of a scrub for any reason on Feb. 18, the backup launch opportunity is 9:38 a.m. Sunday, Feb. 19.
Technically all appears to be on track for the historic first launch of a Falcon 9 from pad 39A pending further reviews and updates from NASA and SpaceX on Friday.

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

The SpaceX Falcon 9 rocket was then integrated with the unmanned Dragon CRS-10 cargo freighter was rolled out of the SpaceX processing hangar at the perimeter fence and then up the incline to the top of pad 39A this morning using a dedicated transporter-erector, so crew could begin final preparation for the Saturday morning blastoff.
From atop KSC pad 39B I witnessed the rocket residing horizontally atop pad 39A as technicians further moved the rocket to launch position.
The 22 story tall Falcon 9/Dragon vehicle was erected to vertical launch position later this afternoon at about 4:50 p.m. to conduct additional ground checks and testing.
It will again be lowered to the horizontal position, so that late load cargo items can be stowed inside the Dragon spaceship on Friday before raising the rocket again into the final launch configuration.
This marks the first time any fully integrated rocket has stood on pad 39A for a scheduled launch since the retirement of NASA’s Space Shuttles in July 2011 on the STS-135 mission to the space station.
The historic NASA launch pad was formerly used to launch both America’s space shuttles and astronauts on Apollo/Saturn V moon landing missions as far back as the 1960s.
Dragon is carrying more than 5500 pounds of equipment, gear, food, crew supplies, hardware and NASA’s Stratospheric Aerosol Gas Experiment III (SAGE III) ozone mapping science payload in support of the Expedition 50 and 51 crew members.
SAGE III will measure stratospheric ozone, aerosols, and other trace gases by locking onto the sun or moon and scanning a thin profile of the atmosphere.
The LIS lightning mapper will measure lightning from the altitude of the ISS. NASA’s RAVEN experiment will test autonomous docking technologies for spacecraft.

The research supplies and equipment brought up by Dragon will support over 250 scientific investigations to advance knowledge about the medical, psychological and biomedical challenges astronauts face during long-duration spaceflight.
About 10 minutes after launch, Dragon will reach its preliminary orbit, deploy its solar arrays and begin a carefully choreographed series of thruster firings to reach the space station.
As a secondary objective SpaceX s planning to attempt to land its Falcon 9 first stage on land at Landing Zone 1 at Cape Canaveral Air Force Station.
‘Astronauts Shane Kimbrough of NASA and Thomas Pesquet of ESA (European Space Agency) will use the station’s robotic arm to capture Dragon when it arrives at the space station after its two-day journey. The spacecraft will be berthed to the Earth-facing port on the Harmony module. The following day, the space station crew will pressurize the vestibule between the station and Dragon, then open the hatch that leads to the forward bulkhead of Dragon,’ according to NASA.

SPACE VIEW PARK/KENNEDY SPACE CENTER, FL – For the first time in more than half a decade, a rocket came to life at NASA’s Kennedy Space Center when a SpaceX Falcon 9 breathed her first fire at historic pad 39A today, Sunday, Feb. 12 – successfully completing a critical static test firing of the first stage engines that opens the door to a launch to the space station next weekend for NASA.
The hot fire test generated a huge plume of smoke exhausting out the north side of the flame trench of Launch Complex 39A at approximately 4:30 p.m. EST, Feb. 12.
The hold down engine test with the erected rocket involved the ignition of all nine Merlin 1D first stage engines generating some 1.7 million pounds of thrust at pad 39A – which has been repurposed from its days as a shuttle launch pad.
The Merlin 1D engines fired for about 3 seconds while the two stage rocket was restrained on the pad.
SpaceX confirmed the test via social media shortly after it took place.
“First static fire test of Falcon 9 at historic launch complex 39A completed in advance of Dragon’s upcoming mission to the @Space_Station,” SpaceX tweeted in a very brief announcement.
I watched excitedly from a public viewing spot at Space View Park in Titusville as the exhaust plume grew quickly in size to a gigantic grey-white colored mushroom cloud of smoke and ash, heaving out the north side of the flame trench silent since the shuttle era.
Then just as quickly the smoke cloud dissipated completely within about 10 minutes leaving barely a trace of what we can expect to see soon.
Titusville offers a prime viewing location for anyone interested in traveling to the Florida Space Coast to see this Falcon 9 launch in person.

The test confirms that both the first stage engines and the rocket are suited for liftoff. Over the past few days, launch teams also tested the pad equipment, raised and lowered the rocket and conducted fit checks of the rocket at the pad.
The test had been delayed several days as technicians coped with issues until all was right to carry out the static fire test.
The positive outcome paves the path for a Falcon 9.Dragon blastoff as soon as next Saturday.
This marks the first time any rocket has stood on pad 39A and fired its engines since the retirement of NASA’s Space Shuttles in July 2011 on the STS-135 mission to the space station.

After the successful completion of the static fire test, the booster will be rolled back to the big processing hangar and the Dragon resupply ship will be integrated on top.
The historic NASA launch pad was formerly used to launch both America’s space shuttles and astronauts on Apollo/Saturn V moon landing missions.

SpaceX was previously employing pad 40 on Cape Canaveral Air Force Station for Falcon 9 launches to the ISS as well as commercial launches.
But pad 40 suffered severe damage following the unexpected launch pad explosion on Sept 1, 2016 that completely destroyed a Falcon 9 and the $200 million Amos-6 commercial payload during a prelaunch fueling test.
An accident investigation revealed that a second stage helium tank burst due to friction ignition during the fueling test.
SpaceX modified the fueling procedures as a short term fix and is working on redesigning the second stage as a long term fix.
SpaceX is working to repair and refurbish pad 40. It is not known when it will be ready to resume launches.
Thus SpaceX has had to switch launch pads for near term future flights and press pad 39A into service much more urgently, speeding up the refurbishing and repurposing work which at last is sufficient to launch rockets again.
Pad 39A has lain dormant for launches for nearly six years since Space Shuttle Atlantis launched on the final shuttle mission STS 135 in July 2011.

KENNEDY SPACE CENTER, FL – The first SpaceX Falcon 9 rocket ever to grace historic launch pad 39A at NASA’s Kennedy Space Center in Florida was erected this afternoon, Friday, Feb. 10, to prepare the booster for a critical static fire sometime Saturday, and a launch to the space station next weekend – if all goes well.
This marks the first time any rocket has stood on pad 39A since the retirement of NASA’s Space Shuttles in July 2011.

The historic NASA launch pad was formerly used to launch both America’s space shuttles and astronauts on Apollo/Saturn V moon landing missions.
SpaceX CEO Elon Musk also posted a photo on instagram with this caption:

After the successful completion of the static fire test, the booster will be rolled back to the big processing hangar and the Dragon resupply ship will be integrated on top.
During the brief static fire test, all 9 Merlin 1D first stage engines are ignited for a few seconds to confirm they and the rocket are suited for liftoff while hold down clamps restrain the rocket on the pad.
Dragon will be loaded with more than 5500 pounds of equipment, gear, food, supplies and NASA’s Stratospheric Aerosol Gas Experiment III (SAGE III) ozone mapping science payload.

In a significant move towards further expansion of the International Space Station’s (ISS) burgeoning research and commercial space economy capabilities, NASA has approved the development of the first privately developed airlock and is targeting blastoff to the orbiting lab complex in two years.
Plans call for the commercial airlock to be launched on a commercial cargo vessel and installed on the U.S. segment of the ISS in 2019.
It enhances the US capability to place equipment and payloads outside and should triple the number of small satellites like CubeSats able to be deployed.
The privately funded commercial airlock is being developed by Nanoracks in partnership with Boeing, which is the prime contractor for the space station.
The airlock will be installed on an open port on the Tranquility module – that already is home to the seven windowed domed Cupola observation deck and the commercial BEAM expandable module built by Bigelow Aerospace.
“We want to utilize the space station to expose the commercial sector to new and novel uses of space, ultimately creating a new economy in low-Earth orbit for scientific research, technology development and human and cargo transportation,” said Sam Scimemi, director, ISS Division at NASA Headquarters in Washington, in a statement.
“We hope this new airlock will allow a diverse community to experiment and develop opportunities in space for the commercial sector.”
The airlock will launch aboard one of NASA’s commercial cargo suppliers in 2019. But the agency has not specified which contractor. The candidates include the SpaceX cargo Dragon, an enhanced ATK Cygnus or potentially the yet to fly SNC Dream Chaser.
Boeing will supply the airlock’s Passive Common Berthing Mechanism (CBM) hardware to connect it to the Tranquility module.

The airlock will beef up the capability of transferring equipment, payloads and deployable satellites from inside the ISS to outside, significantly increasing the utilization of ISS, says Boeing.
“The International Space Station allows NASA to conduct cutting-edge research and technology demonstrations for the next giant leap in human exploration and supports an emerging space economy in low-Earth orbit. Deployment of CubeSats and other small satellite payloads from the orbiting laboratory by commercial customers and NASA has increased in recent years. To support demand, NASA has accepted a proposal from NanoRacks to develop the first commercially funded airlock on the space station,” says NASA.
“The installation of NanoRacks’ commercial airlock will help us keep up with demand,” said Boeing International Space Station program manager Mark Mulqueen. “This is a big step in facilitating commercial business on the ISS.”
Right now the US uses the airlock on the Japanese Experiment Module (JEM) to place payloads on the stations exterior as well as for small satellite deployments. But the demand is outstripping the JEM’s availability.
The Nanoracks airlock will be larger and more robust to take up the slack.
NASA has stipulated that the Center for the Advancement of Science in Space (CASIS), NASA’s manager of the U.S. National Laboratory on the space station, will be responsible for coordinating all payload deployments from the commercial airlock – NASA and non NASA.
“We are entering a new chapter in the space station program where the private sector is taking on more responsibilities. We see this as only the beginning and are delighted to team with our friends at Boeing,” said Jeffrey Manber, CEO of NanoRacks.
The NanoRacks commercial airlock could potentially launch to the ISS in the trunk of a SpaceX cargo Dragon.

KENNEDY SPACE CENTER, FL – With liftoff tentatively penciled in for mid-February, SpaceX still awaits FAA approval of a launch license for what will be the firms first Falcon 9 rocket to launch from historic pad 39A at the Kennedy Space Center – on a critical NASA mission to resupply the space station – the Federal Aviation Administration (FAA) confirmed today to Universe Today.
“The FAA is working closely with SpaceX to ensure the activity described in the application meets all applicable regulations for a launch license,” FAA spokesman Hank Price confirmed to Universe Today.
As of today, Feb. 7, SpaceX has not yet received “a license determination” from the FAA – as launch vehicle, launch pad and payload preparations continue moving forward for blastoff of the NASA contracted flight to carry science experiments and supplies to the International Space Station (ISS) aboard a SpaceX cargo Dragon atop an upgraded SpaceX Falcon 9 rocket from Launch Complex 39A on the Florida Space Coast.
“The FAA will continue to work with SpaceX to provide a license determination in a timely manner,” Price told me.
SpaceX currently has license applications pending with the FAA for both the NASA cargo launch and pad 39A. No commercial launch can take place without FAA approval.

The goal of the 22-story tall SpaceX Falcon 9 is to carry an unmanned Dragon cargo freighter for the NASA customer on the CRS-10 resupply mission to the International Space Station (ISS).
Dragon will be loaded with more than two tons of equipment, gear, food, supplies and NASA’s Stratospheric Aerosol Gas Experiment III (SAGE III) ozone mapping science payload.

The historic NASA launch pad was formerly used to launch both America’s space shuttles and astronauts on Apollo/Saturn V moon landing missions.
SpaceX, founded by billionaire CEO Elon Musk, leased Launch Complex 39A from NASA back in April 2014 and is modifying and modernizing the pad for unmanned and manned launches of the Falcon 9 as well as the Falcon Heavy.
The role of the FAA is to license commercial launches and protect the public.
“The FAA licenses commercial rocket launches and reentries to ensure the protection of public health and safety,” Price elaborated.
Last week SpaceX announced a shuffled launch schedule, whereby the NASA cargo flight on the CRS-10 resupply mission was placed first in line for liftoff from pad 39A – ahead of a commercial EchoStar communications satellite.
The aerospace company said the payload switch would allow additional time was to complete all the extensive ground support work and pad testing required for repurposing seaside Launch Complex 39A from launching the NASA Space Shuttle to the SpaceX Falcon 9.
The inaugural Falcon 9 blastoff from pad 39A has slipped repeatedly from January into February 2017.
The unofficial most recently targeted ‘No Earlier Than’ NET date for CRS-10 has apparently slipped from NET Feb 14 to Feb 17.
CRS-10 counts as SpaceX’s tenth cargo flight to the ISS since 2012 under contract to NASA.
Further launch postponements are quite possible at any time and NASA is officially stating a goal of “NET mid-February” – but with no actual target date specified.

Crews have been working long hours to transform and refurbish pad 39A and get it ready for Falcon 9 launches. Furthermore, a newly built transporter erector launcher was seen raised at the pad multiple times in recent weeks. The transporter will move the rocket horizontally up the incline at the pad, and then erect it vertically for launch.
SpaceX was previously employing pad 40 on Cape Canaveral Air Force Station for Falcon 9 launches to the ISS as well as commercial launches.
But pad 40 suffered severe damage following the unexpected launch pad explosion on Sept 1, 2016 that completely destroyed a Falcon 9 and the $200 million Amos-6 commercial payload during a prelaunch fueling test.
Furthermore it is not known when pad 40 will be ready to resume launches.
Thus SpaceX has had to switch launch pads for near term future flights and press pad 39A into service much more urgently, and the refurbishing and repurposing work is not yet complete.
Pad 39A has lain dormant for launches for nearly six years since Space Shuttle Atlantis launched on the final shuttle mission STS 135 in July 2011.
To date SpaceX has not rolled a Falcon 9 rocket to pad 39A, not raised it to launch position, not conducted a fueling exercise and not conducted a static fire test. All the fit checks with a real rocket remain to be run.

Once the pad is ready, SpaceX plans an aggressive launch schedule in 2017.
“The launch vehicles, Dragon, and the EchoStar satellite are all healthy and prepared for launch,” SpaceX stated.
The history making first use of a recycled Falcon 9 carrying the SES-10 communications satellite could follow as soon as March or April, if all goes well – as outlined here.
Stay tuned here for Ken’s continuing Earth and Planetary science and human spaceflight news.

KENNEDY SPACE CENTER, FL – SpaceX announced Sunday (Jan. 29) a significant shuffle to the Falcon 9 launch schedule, saying that a key NASA mission to resupply the space station is moving to the head of the line and will now be their first mission to launch from historic pad 39A at the Kennedy Space Center – formerly used to launch space shuttles.
The late breaking payload switch will allow SpaceX, founded by billionaire CEO Elon Musk, additional time to complete all the extensive ground support work and pad testing required for repurposing seaside Launch Complex 39A from launching the NASA Space Shuttle to the SpaceX Falcon 9.
Blastoff of the 22-story tall SpaceX Falcon 9 carrying an unmanned Dragon cargo freighter with NASA as customer on the CRS-10 resupply mission to the International Space Station (ISS) could come as soon as mid-February, said SpaceX.
“SpaceX announced today that its first launch from Launch Complex 39A (LC-39A) at NASA’s Kennedy Space Center in Florida will be the CRS-10 mission to the International Space Station,” said SpaceX in a statement.
CRS-10 counts as SpaceX’s tenth cargo flight to the ISS since 2012 under contract to NASA.

Crews have been working long hours to modify pad 39A and get it ready for Falcon 9 launches. Also, the newly built transporter erector launcher was seen raised at the pad multiple times in recent days. The transporter will move the rocket horizontally up the incline at the pad, and then erect it vertically.
“This schedule change allows time for additional testing of ground systems ahead of the CRS-10 mission,” SpaceX announced in a statement.
The surprise switch in customers means that the previously planned first Falcon 9 launch from pad 39A of the commercial EchoStar 23 communications satellite is being pushed off to a later date – perhaps late February.
Until now, EchoStar 23 was slated to be the first satellite launched by a Falcon 9 from Launch Complex 39A on NASA’s Kennedy Space Center. It could have come as soon as by the end of this week.
However, the Falcon 9 launch date from pad 39A has slipped repeatedly in January, with this week on Feb. 3 as the most recently targeted ‘No Earlier Than’ NET date.
SpaceX successfully resumed launches of the Falcon 9 earlier this month when the first flock of 10 Iridium NEXT mobile voice and data relay satellites blasted off on the Iridium 1 mission from Vandenberg Air Force Base in California on Jan. 14, 2017.
NASA now gets the first dibs for using pad 39A which has lain dormant for nearly six years since Space Shuttle Atlantis launched on the final shuttle mission STS 135 in July 2011.
The last Dragon resupply mission to the ISS blasted off on July 18, 2016 on the CRS-9 mission. The Falcon 9 first stage was also successfully recovered via a propulsive soft landing back at the Cape at night.

The last successful Falcon 9 launch from Space Launch Complex-40 took place on Aug. 14, 2016, carrying the JCSAT-16 Japanese communications satellite to orbit.

But following the unexpected launch pad explosion on Sept 1, 2016 that completely destroyed a Falcon 9 and the $200 million Amos-6 commercial payload during a prelaunch fueling test, pad 40 suffered extensive damage.
Furthermore it is not known when the pad will be ready to resume launches.

So SpaceX has had to switch launch pads for near term future flights and press pad 39A into service much more urgently, and the refurbishing and repurposing work is not yet complete.
To date SpaceX has not rolled a Falcon 9 rocket to pad 39A, not raised it to launch position, not conducted a fueling exercise and not conducted a static fire test. All the fit checks with a real rocket remain to be run.
Thus the current launch target of mid-February for CRS-10 remains a target date and not a firm launch date. EchoStar 23 is next in line.
“The launch is currently targeted for no earlier than mid-February,” SpaceX elaborated.
“Following the launch of CRS-10, first commercial mission from 39A is currently slated to be EchoStar XXIII.”
Once the pad is ready, SpaceX plans an aggressive launch schedule in 2017.
“The launch vehicles, Dragon, and the EchoStar satellite are all healthy and prepared for launch,” SpaceX stated.
The history making first use of a recycled Falcon 9 carrying the SES-10 communications satellite could follow as soon as March, if all goes well.
