There’s an oft-used idiom that you can’t see political borders from space, but we’ve known for a while it’s no longer true. Between higher resolution cameras and the increase in human activity, there have been several examples of borders visible from space. Here’s one more.
Astronauts aboard the International Space Station took this photograph in November of 2014 of a 20-kilometer (12-mile) stretch of the Iraq-Iran border, near the coast of the Persian Gulf. Clearly visible is the border between the two countries, along with signs of fortification: circular gun emplacements, systems of large curved earthworks and straight connecting roads that run parallel to the border.
NASA said the ISS team that analyzes astronaut photos first thought the circular features to be oil-pad installations (like ones seen in Texas here). But they said the “strategic location of these formations along the international boundary made it easier to see these as patterns of military fortifications. This region of oil refining and exporting was the center of numerous military actions during the war in the 1980s, especially during the defense of the southern city of Basra.”
Back in 2011, we featured an image from astronaut Ron Garan which clearly showed the human-made border between India and Pakistan. Since 2003, India has illuminated the border with Pakistan by floodlights in attempt to prevent ammunition trafficking and the infiltration of terrorists.
This picture shows the illuminated man-made border between India and Pakistan,the line snaking through the landscape, as seen from the International Space Station on August 21, 2011. Of the hundreds of clusters lights, the largest are the capital cities of Islamabad, Pakistan, and New Delhi, India. Credit: NASA/Ron Garan
“Realizing what this picture depicted had a big impact on me,” Garan said. “When viewed from space, Earth almost always looks beautiful and peaceful. However, this picture is an example of man-made changes to the landscape in response to a threat, clearly visible from space. This was a big surprise to me.”
There’s also a satellite photo from the M-Sat Planet Observer showing the clear border and demilitarized zone between North and South Korea.

NASA pays tribute to the crews of Apollo 1 and space shuttles Challenger and Columbia
Today, Feb. 1, concludes the most somber week in NASA history as we remember the fallen astronauts who gave their lives exploring space so that others could reach to the stars – venturing further than ever before!
In the span of a week and many years apart three crews of American astronauts made the ultimate sacrifice and have perished since 1967. Heroes all ! – They believed that the exploration of space was worth risking their lives for the benefit of all mankind.

“Today we remember and give thanks for the lives and contributions of those who gave all trying to push the boundaries of human achievement. On the solemn occasion, we pause in our normal routines and remember the STS-107 Columbia crew; the STS-51L Challenger crew; the Apollo 1 crew; Mike Adams, the first in-flight fatality of the space program as he piloted the X-15 No. 3 on a research flight; and those lost in test flights and aeronautics research throughout our history,” said Bolden.
“Let us join together … in paying our respects, and honoring the memories of our dear friends. They will never be forgotten. Godspeed to every one of them.”
12 years ago today on Saturday, Feb. 1, 2003, Space Shuttle Columbia suddenly and unexpectedly disintegrated over the skies of Texas during the fiery reentry into the Earth’s atmosphere at the conclusion of the STS-107 science mission. All aboard were lost: Rick Husband, William McCool, David Brown, Laurel Clark, Kalpana Chawla, Michael Anderson, and Ilan Ramon.

The Falcon Heavy is the brainchild of billionaire entrepreneur Elon Musk, SpaceX CEO and founder, and illustrates his moving forward with the firm’s next giant leap in spaceflight.
The rocket is designed to lift over 53 tons (117,00 pounds) to orbit and could one day launch astronauts to the Moon and Mars.
The commercial Falcon Heavy rocket has been under development by SpaceX for several years and the initial launch is now planned for later this year from Launch Complex 39A at the Kennedy Space Center (KSC) in Florida.
The new rocket is comprised of three Falcon 9 cores.
The Falcon Heavy will be the most powerful rocket developed since NASA’s Saturn V rocket that hurled NASA’s Apollo astronauts to the Moon in the 1960s and 1970s – including the first manned landing on the Lunar surface by Neil Armstrong and Buzz Aldrin in July 1969.
Here is the updated animation of the SpaceX Falcon Heavy flight and booster recovery:

The video shows the launch of the triple barreled Falcon Heavy from Launch Complex 39A at NASA’s Kennedy Space Center in Florida. Then it transitions to the recovery of all three boosters by a guided descent back to a soft touchdown on land in the Cape Canaveral/Kennedy Space Center area.
SpaceX, headquartered in Hawthorne, CA, signed a long term lease with NASA in April 2014 to operate seaside pad 39A as a commercial launch facility for launching the Falcon Heavy as well as the manned Dragon V2 atop SpaceX’s man-rated Falcon 9 booster.
Launch Complex 39A has sat dormant for over three years since the blastoff of the final shuttle mission STS-135 in July 2011 on a mission to the International Space Station (ISS).

SpaceX is now renovating and modifying the pad as well as the Fixed and Mobile Service Structures, RSS and FSS. They will maintain and operate Pad 39A at their own expense, with no US federal funding from NASA.
When it does launch, the liquid fueled Falcon Heavy will become the most powerful rocket in the world according to SpaceX, generating nearly four million pounds of liftoff thrust from 27 Merlin 1D engines. It will then significantly exceeding the power of the Delta IV Heavy manufactured by competitor United Launch Alliance (ULA), which most recently was used to successfully launch and recover NASA’s Orion crew capsule on its maiden unmanned flight in Dec. 2014

SpaceX recently completed a largely successful and history making first attempt to recover a Falcon 9 booster on an ocean-going “drone ship.” The rocket nearly made a pinpoint landing on the ship but was destroyed in the final moments when control was lost due to a loss of hydraulic fluid.
Read my story with a SpaceX video – here – that vividly illustrates what SpaceX is attempting to accomplish by recovering and ultimately reusing the boosters in order to dramatically cut the cost of access to space.

“Robotic controllers let the CATS out of the bag!” So says NASA spokesman Dan Huot in a cool new NASA timelapse video showing in detail how CATS crawled around the space stations gangly exterior and clawed its way into its new home – topped off with a breathtaking view of our home planet that will deliver science benefits to us down below.
The CATS experiment was installed on the exterior of the International Space Station (ISS) via a first ever type of robotic handoff, whereby one of the stations robotic arms handed the rectangular shaped instrument off to a second robotic arm. Sort of like relays runners passing the baton while racing around the track for the gold medal.
In this case it was all in the name of science. CATS is short for Cloud Aerosol Transport System.
Ground controllers at NASA’s Johnson Space Center in Houston plucked CATS out of the truck of the recently arrivedSpaceX Dragon cargo delivery vehicle with the Special Purpose Dexterous Manipulator (Dextre). Then they passed it off to a Japanese team of controllers at JAXA, manipulating the second arm known as the Japanese Experiment Module Remote Manipulator System. The JAXA team then installed CATS onto an external platform on Japans Kibo laboratory.
CATS is a new Earth Science instrument dedicated to collecting continuous data about clouds, volcanic ash plumes and tiny airborne particles that can help improve our understanding of aerosol and cloud interactions and improve the accuracy of climate change models.
The remote-sensing laser instrument measures clouds and the location and distribution of pollution, dust, smoke, and other particulates and aerosols in the atmosphere that directly impacts the global climate.
Data from CATS will be used to derive properties of cloud/aerosol layers at three wavelengths: 355, 532, 1064 nm.

All the movements were conducted overnight by robotic flight controllers on the ground. They installed CATS to an external platform on Japan’s Kibo lab module.
CATS is helping to open a new era on the space station research dedicated to expanding its use as a science platform for making extremely valuable remote sensing observations for Earth Science.
The CATS instrument is the fourth successful NASA Earth science launch out of five scheduled during a 12-month period. And it is the second to be installed on the exterior of the ISS, following ISS-RapidScat that was brought by the SpaceX CRS-4 Dragon.
The fifth launch — the Soil Moisture Active Passive satellite — is scheduled for Jan. 29 from Vandenberg Air Force Base in California.
CATS was launched to the station as part of the payload aboard the SpaceX Dragon CRS-5 cargo vessel bolted atop the SpaceX Falcon 9 for the spectacular nighttime blastoff on Jan. 10 at 4:47 a.m. EST from Cape Canaveral Air Force Station in Florida.
CATS was loaded in the unpressurized rear trunk section of Dragon.

The Dragon CRS-5 spacecraft was loaded with over 5108 pounds (2317 kg) of scientific experiments, technology demonstrations, the CATS science payload, student research investigations, crew supplies, spare parts, food, water, clothing and assorted research gear for the six person crew serving aboard the ISS.
It successfully rendezvoused at the station on Jan. 12 after a two day orbital chase, delivering the critical cargo required to keep the station stocked and humming with science.

President Obama gave a shout out to NASA Astronaut Scott Kelly and his upcoming 1 year mission to the International Space Station at the 2015 State of the Union address to the US Congress on Tuesday evening, Jan. 20, 2015.
Obama wished Kelly (pictured above in the blue jacket) good luck during his address and told him to send some photos from the ISS via Instagram. Kelly was seated with the First Lady, Michelle Obama, during the speech on Capitol Hill.
The TV cameras focused on Kelly and he was given a standing ovation by the Congress and the President.
Obama also praised Kelly’s flight and the recent Dec. 5, 2014, launch of NASA’s Orion deep space capsule as “part of a re-energized space program that will send American astronauts to Mars.”
Watch this video of President Obama hailing NASA and Scott Kelly:

Here’s a transcript of President Obama’s words about NASA, Orion, and Scott Kelly’s 1 Year ISS mission:
“Pushing out into the Solar System not just to visit, but to stay. Last month, we launched a new spacecraft as part of a re-energized space program that will send American astronauts to Mars. In two months, to prepare us for those missions, Scott Kelly will begin a year-long stay in space. Good luck, Captain and make sure to Instagram it.”
In late March, Astronaut Scott Kelly will launch to the International Space Station and become the first American to live and work aboard the orbiting laboratory for a year-long mission.
Scott Kelly and Russian Cosmonaut Mikhail Kornienko, both veteran spacefliers, comprise the two members of the 1 Year Mission crew.
Normal ISS stays last for about a six month duration.

No American has ever spent anywhere near a year in space. 4 Russian cosmonauts conducted long duration stays of about a year or more in space aboard the Mir Space Station in the 1980s and 1990s.
Together with Russian cosmonaut Gennady Padalka, Kelly and Kornienko will launch on a Russian Soyuz capsule from the Baikonur Cosmodrome as part of Expedition 44.
Kelly and Kornienko will stay aboard the ISS until March 2016.
They will conduct hundreds of science experiments focusing on at least 7 broad areas of investigation including medical, psychological, and biomedical challenges faced by astronauts during long-duration space flight.

Dramatic new photos and video of the daring and mostly successful attempt by Space X to land their Falcon 9 booster on an ocean-going “drone ship” were released this morning, Friday, Jan. 16, by SpaceX CEO and founder Elon Musk.
Musk posted the imagery online via his twitter account and they vividly show just how close his team came to achieving total success in history’s first attempt to land and recover a rocket on a tiny platform in the ocean.
Here’s the video: “Close, but no cigar. This time.”
The history making attempt at recovering the Falcon 9 first stage was a first of its kind experiment to accomplish a pinpoint soft landing of a rocket onto a miniscule platform at sea using a rocket assisted descent by the first stage Merlin engines aided by steering fins.
The first stage rocket reached an altitude of over 100 miles after firing nine Merlins as planned for nearly three minutes. It had to be slowed from traveling at a velocity of about 2,900 mph (1300 m/s). The descent maneuver has been likened to someone balancing a rubber broomstick on their hand in the middle of a fierce wind storm.
The imagery shows the last moments of the descent as the rocket hits the edge of the drone ship at a 45 degree angle with its four landing legs extended and Merlin 1D engines firing.

Musk tweeted that the first stage Falcon 9 booster ran out of hydraulic fluid and thus hit the barge.
“Rocket hits hard at ~45 deg angle, smashing legs and engine section,” Musk explained today.
Lacking hydraulic fluid the boosters attached steering fins lost power just before impact.
“Before impact, fins lose power and go hardover. Engines fights to restore, but …,” Musk added.

This ultimately caused the Falcon 9 to crash land as the legs and engine section were smashed and destroyed as the fuel and booster burst into flames. The ship survived no problem.
“Residual fuel and oxygen combine.”
“Full RUD (rapid unscheduled disassembly) event. Ship is fine minor repairs. Exciting day!” said Musk.
“Rocket made it to drone spaceport ship, but landed hard. Close, but no cigar this time. Bodes well for the future tho,” Musk tweeted within hours after the launch and recovery attempt.
As I wrote on launch day here at Universe Today, despite making a ‘hard landing’ on the vessel dubbed the ‘autonomous spaceport drone ship,’ the 14 story tall Falcon 9 first stage did make it to the drone ship, positioned some 200 miles offshore of the Florida-Carolina coast, northeast of the launch site in the Atlantic Ocean. The rocket broke into pieces upon hitting the barge.
Whereas virtually every other news outlet quickly declared the landing attempt a “Failure” in the headline, my assessment as a scientist and journalist was the complete opposite!!
In my opinion the experiment was “a very good first step towards the bold company goal of recovery and re-usability in the future” as I wrote in my post launch report here at Universe Today.
Listen to my live radio interview with BBC 5LIVE conducted Saturday night (Jan. 11 UK time), discussing SpaceX’s first attempt to land and return their Falcon-9 booster.
“Is it safe? Was SpaceX brave or foolhardy? Why is this significant? Will SpaceX succeed in the future?” the BBC host asked me.
SpaceX achieved virtually all of their objectives in the daunting feat except for a soft landing on the drone ship.
This was a bold experiment involving re-lighting one of the first stage Merlin 1D engines three times to act as a retro rocket to slow the stages descent and aim for the drone ship.
Four attached hypersonic grid fins and a trio of Merlin propulsive burns succeeded in slowing the booster from hypersonic velocity to subsonic and guiding it to the ship.
The drone ship measures only 300 feet by 170 feet. That’s tiny compared to the Atlantic Ocean.
The first stage was planned to make the soft landing by extending four landing legs to a width of about 70 feet to achieve an upright landing on the platform with a accuracy of 30 feet (10 meters).
No one has ever tried such a landing attempt before in the ocean says SpaceX. The company has conducted numerous successful soft landing tests on land. And several soft touchdowns on the ocean’s surface. But never before on a barge in the ocean.
So they will learn and move forward to the next experimental landing, that could come as early as a few weeks on the launch of the DSCOVR mission in late January or early February.
“Upcoming flight already has 50% more hydraulic fluid, so should have plenty of margin for landing attempt next month.”

Musk’s daring vision is to recover, refurbish and reuse the first stage and dramatically reduce the high cost of access to space, by introducing airline like operational concepts.
It remains to be seen whether his vision of reusing rockets can be made economical. Most of the space shuttle systems were reused, except for the huge external fuel tanks, but it was not a cheap proposition.
But we must try to cut rocket launch costs if we hope to achieve routine and affordable access to the high frontier and expand humanity’s reach to the stars.
The Falcon 9 launch itself was a flawless success, blasting off at 4:47 a.m. EST on Jan. 10 from Space Launch Complex 40 at Cape Canaveral Air Force Station in Florida.
The Dragon CRS-5 spacecraft was loaded with over 5108 pounds (2317 kg) of scientific experiments, technology demonstrations, the CATS science payload, student research investigations, crew supplies, spare parts, food, water, clothing and assorted research gear for the six person crew serving aboard the ISS.

Nearly twelve hours after the threat of a leak of toxic ammonia forced the crew into a middle of the night evacuation from the US side of the International Space Station this morning (Jan. 14) and a hatch closure, top level managers from the partner space agencies gave the all clear and allowed the astronauts and cosmonauts to reopen access to the American portion of the orbiting outpost.
The six person crew hailing from the US, Italy and Russia were allowed to open the sealed hatch to the U.S. segment later this afternoon after it was determined that the ammonia leak was quite fortunately a false alarm.
No ammonia leak was actually detected. But the crew and mission control had to shut down some non essential station systems on the US segment in the interim.
All the Expedition 42 crew members were safe and in good health and never in danger, reported NASA.
The station crews and mission control teams must constantly be prepared and train for the unexpected and how to deal with potential emergencies, such as today’s threat of a serious chemical leak.
After a thorough review of the situation by the International Space Station mission management team, the crew were given the OK by flight controllers to head back.
They returned inside at 3:05 p.m. EST. Taking no chances, they wore protective masks and sampled the cabin atmosphere and reported no indications of any ammonia.
Fears that a leak had been detected resulted from the sounding of an alarm at around 4 a.m. EST.
The alarm forced Expedition 42 station commander Barry Wilmore and Flight Engineer Terry Virts of NASA and Flight Engineer Samantha Cristoforetti of the European Space Agency to don protective gas masks and move quickly into the Russian segment, sealing the hatch behind them to the US segment.
Inside the Russian segment, they joined the remainder of Expedition 42, namely cosmonauts Aleksandr Samokutyayev, Yelena Serova, and Anton Shkaplerov from Russia, also living and working aboard the ISS and rounding out the crew of four men and two women.

“The alarm is part of the environmental systems software on the station designed to monitor the cabin’s atmosphere. At the same time, the station’s protection software shut down one of two redundant cooling loops (Thermal Control System Loop B),” NASA said in an update.
Ammonia is a toxic substance used as a coolant in the stations complex cooling system that is an essential requirement to continued operation of the station.
Ammonia is a gas at room temperature that is extremely dangerous to inhale or when it comes in contact with skin, eyes and internal organs.
Precautions must be taken if a leak is feared in a confined space such as the ISS. It has about the same habitable volume as a four bedroom house.
As a professional chemist, I’ve worked frequently with ammonia in research and development labs and manufacturing plants and know the dangers firsthand. It can cause severe burns and irritations and worse.
There have been prior ammonia leaks aboard the ISS facility that forced a partial evacuation similar to today’s incident.
The ISS has been continuously occupied by humans for 15 years.
In the case of a life threatening emergency, the crew can rapidly abandon the station aboard the two docked Russian Soyuz capsules. They hold three persons each and serve as lifeboats.
Fortunately, the perceived ammonia leak this morning was not real and apparently was caused by a false alarm.
“This morning’s alarm is suspected to have been caused by a transient error message in one of the station’s computer relay systems, called a multiplexer-demultiplexer. A subsequent action to turn that relay box off and back on cleared the error message and the relay box is reported by flight controllers to be in good operating condition,” according to a NASA statement.
“Meanwhile, flight controllers are continuing to analyze data in an effort to determine what triggered the alarm that set today’s actions in motion.”
“Work to reactivate cooling loop B on the station will continue throughout the night and into the day Thursday. The crew members are expected to resume a normal complement of research activities on Thursday as well.”

Breaking News: A possible ammonia leak aboard the US side of the International Space Station (ISS) has forced a partial evacuation of the entire crew to the Russian side earlier this morning, Wednesday, Jan. 14.
All six crew members from the US, Italy and Russia are safe and in good shape at this time, says NASA and Roscosmos, the Russian Federal Space Agency.
Hatches between the US and Russian segments were sealed shut, pending further analysis.
Mission controllers are in the process of assessing whether it’s a real leak or a false alarm due to a faulty sensor or a computer problem. It’s not completely clear at this time.
The latest indications at 11 a.m. EST, Jan. 14, are that it may be a false alarm, says NASA.
“The security of a crew was guaranteed thanks to correct actions of the cosmonauts, astronauts and the crew of the Mission control centres in Moscow and Houston. Further plan of actions in the US modules must be prepared in Houston,” according to Roscosmos.
“For now NASA colleagues are analyzing situation”, – noted the head of Russian Mission Control Centre Maxim Matushin
Ammonia is a toxic substance used as a coolant in the stations complex cooling system that is an essential requirement to continued operation of the station.
There have been prior ammonia leaks aboard the ISS facility.
NASA announced that an alarm sounded in the US segment at about 4 a.m. EST. indicating a possible ammonia leak. As a result, all six Expedition 42 astronauts and cosmonauts evacuated the US segment.
“Flight controllers in Mission Control at NASA’s Johnson Space Center in Houston saw an increase in pressure in the station’s water loop for thermal control system B then later saw a cabin pressure increase that could be indicative of an ammonia leak in the worst case scenario,” according to a NASA announcement.
Therefore as a precaution after the alarm sounded earlier today, the crew was directed to isolate themselves in the Russian segment this morning while teams are evaluating the situation. The crew powered down non-essential equipment in the U.S. segment of the station according to established procedures, said NASA.
“In an exchange at 7:02 a.m. with Expedition 42 Commander Barry Wilmore of NASA, spacecraft communicator James Kelly said flight controllers were analyzing their data but said it is not yet known if the alarm was actually triggered by a leak or whether the situation was caused by a faulty sensor or by a problem in a computer relay box that sends data and commands to various systems on the station.”
The evacuation comes just two days after a commercial SpaceX Dragon cargo freighter successfully rendezvoused and berthed at the station on Monday, Jan. 11.

The ISS has been continuously occupied by humans for 15 years.
The current six person crew includes astronauts and cosmonauts from three nations; America, Russia and Italy including four men and two women serving aboard the massive orbiting lab complex.
They comprise Expedition 42 Commander Barry “Butch” Wilmore and Terry Virts from NASA, Samantha Cristoforetti from the European Space Agency (ESA) and cosmonauts Aleksandr Samokutyayev, Yelena Serova, and Anton Shkaplerov from Russia.

The commercial SpaceX cargo Dragon, loaded with over 2.6 tons of critically needed supplies and science experiments, was captured by the crew aboard the International Space Station (ISS) this morning (Jan. 12) while soaring over the Mediterranean Sea.
The SpaceX Dragon CRS-5 cargo vessel arrived at the station following a flawless two day orbital pursuit and spectacular nighttime blastoff atop the SpaceX Falcon 9 on Jan. 10 at 4:47 a.m. EST from Cape Canaveral Air Force Station in Florida.

Dragon was successfully berthed and bolted into place a few hours later at 8:54 a.m. EST.
Working at the robotics work station inside the seven windowed domed cupola, Expedition 42 Commander Barry “Butch” Wilmore of NASA, with the assistance of Flight Engineer Samantha Cristoforetti of the European Space Agency, successfully captured the Dragon spacecraft with the station’s Canadian-built robotic arm at 5:54 a.m. EST.
Wilmore grappled Dragon with the station’s 57-foot-long (17-meter-long) robotic arm at 5:54 a.m. EST, about 18 minutes ahead of schedule, in an operation shown live on NASA TV, back-dropped by breathtaking views of “our beautiful Earth” passing by some 260 miles (410 kilometers) below.
Among the goodies aboard are belated Christmas presents for the crew. The Falcon 9 and Dragon were originally scheduled to liftoff in December and arrive in time for the Christmas festivities.
The cargo freighter flew beneath the station to arrive at the capture point 32 feet (10 meters) away. Dragon’s thrusters were disabled at the time of grappling.
Robotics officers at Houston Mission Control then began remotely maneuvering the arm to berth Dragon at the Earth-facing port on the station’s Harmony module starting at 7:45 a.m. EST.
Dragon is being attached via the common berthing mechanism (CBM) using four gangs of four bolts apiece to accomplish a hard mate to Harmony. The overall grappling and berthing process requires a few hours.
Dragon was successfully berthed and bolted into place at 8:54 a.m. EST and its now part of the space station.
The crew will conduct leak pressure checks, remove the docking mechanism and open the hatch later today or tomorrow.

CRS-5 marks the company’s fifth operational resupply mission to the ISS under a $1.6 Billion contract with NASA to deliver 20,000 kg (44,000 pounds) of cargo to the station during a dozen Dragon cargo spacecraft flights through 2016 under NASA’s Commercial Resupply Services (CRS) contract.
Overall this is the sixth Dragon to arrive at the ISS.
The ISS cannot function without regular deliveries of fresh cargo by station partners from Earth.
The Dragon CRS-5 spacecraft is loaded with over 5108 pounds (2317 kg) of scientific experiments, technology demonstrations, crew supplies, spare parts, food, water, clothing, and assorted research gear for the six person crew serving aboard the ISS.
Among the payloads is the Cloud-Aerosol Transport System (CATS), a remote-sensing laser instrument to measure clouds and the location and distribution of pollution, dust, smoke, and other particulates and aerosols in the atmosphere that directly impact the global climate.
CATS is loaded aboard the unpressurized trunk of Dragon.
Also loaded onboard are 17 student experiments known collectively as the “Yankee Clipper” mission. The experiments are sponsored by the National Center for Earth and Space Science Education, which oversees the Student Spaceflight Experiments Program (SSEP) in partnership with NanoRacks LLC.
The launch marked the first US commercial resupply launch since the catastrophic destruction of an Orbital Sciences Antares rocket and Cygnus Orb-3 spacecraft bound for the ISS which exploded unexpectedly after launch from NASA Wallops, VA, on Oct. 28, 2014.
The US supply train to the ISS is now wholly dependent on SpaceX until Cygnus flights are resumed, hopefully by late 2015, on an alternate rocket, the Atlas V.

Dragon will remain attached to the ISS for about four weeks until Feb. 10.
The history making attempt at recovering the Falcon 9 first stage was a first of its kind experiment to accomplish a pinpoint soft landing of a rocket onto a tiny platform in the middle of a vast ocean using a rocket assisted descent.
In my opinion the experiment was “a very good first step towards the bold company goal of recovery and re-usability in the future” as I wrote in my post launch report here at Universe Today.
Listen to my live radio interview with BBC 5LIVE conducted Saturday night, discussing SpaceX’s first attempt to land and return their Falcon-9 booster.
Stay tuned here for Ken’s continuing Earth and planetary science and human spaceflight news.

SpaceX successfully launched their commercial Falcon 9 rocket and Dragon cargo ship on a critical mission for NASA bound for the space station this morning, Jan. 10, while simultaneously accomplishing a hard landing of the boosters first stage on an ocean-floating “drone ship” platform in a very good first step towards the bold company goal of recovery and re-usability in the future.
The spectacular night time launch of the private SpaceX Falcon 9 rocket lit up the skies all around the Florida Space Coast and beyond following a flawless on time liftoff at 4:47 a.m. EST from Cape Canaveral Air Force Station.
The nine Merlin 1D engines of the 208 foot-tall Falcon 9 generated 1.3 million pounds of liftoff thrust as the rocket climbed to orbit on the first SpaceX launch of 2015.
The Dragon CRS-5 mission is on its way to a Monday-morning rendezvous with the International Space Station (ISS).
It is loaded with more than two tons of supplies and NASA science investigations for the six person crew aboard the massive orbiting outpost.
A secondary goal of SpaceX was to conduct a history-making attempt at recovering the 14 story tall Falcon 9 first stage via a precision landing on an ocean-going landing platform known as the “autonomous spaceport drone ship.”
SpaceX CEO Elon Musk quickly tweeted that good progress was made, and as expected, more work needs to be done.
This was an experiment involving re-lighting one of the first stage Merlin engines three times to act as a retro rocket to slow the stages descent and aim for the drone ship.
“Rocket made it to drone spaceport ship, but landed hard. Close, but no cigar this time. Bodes well for the future tho,” Musk tweeted soon after the launch and recovery attempt.
“Ship itself is fine. Some of the support equipment on the deck will need to be replaced…”
“Didn’t get good landing/impact video. Pitch dark and foggy. Will piece it together from telemetry and … actual pieces.”
Musk’s daring vision is to recover, refurbish and reuse the first stage and dramatically reduce the high cost of access to space, by introducing airline like operational concepts.
The ‘autonomous spaceport drone ship’ was positioned some 200 to 250 miles offshore of the launch site in the Atlantic Ocean along the rockets flight path, flying along the US Northeast coast to match that of the ISS.
The autonomous spaceport drone ship measure only 300 by 100 feet, with wings that extend its width to 170 feet. That’s tiny compared to the Atlantic Ocean.
Therefore the SpaceX team was successful in accomplishing a rocket assisted descent and pinpoint landing in the middle of a vast ocean, albeit not as slow as hoped.
No one has ever tried such a landing attempt before in the ocean says SpaceX. The company has conducted numerous successful soft landing tests on land. And several soft touchdowns on the ocean’s surface. But never before on a barge in the ocean.
So they will learn and move forward to the next experimental landing.

“We are delighted to kick off 2015 with our first commercial cargo launch of the year,” said NASA Administrator Charles Bolden in a statement.
“Thanks to our private sector partners, we’ve returned space station resupply launches to U.S. soil and are poised to do the same with the transport of our astronauts in the very near future.”
“Today’s launch not only resupplies the station, but also delivers important science experiments and increases the station’s unique capabilities as a platform for Earth science with delivery of the Cloud-Aerosol Transport System, or CATS instrument. I congratulate the SpaceX and NASA teams who have made today’s success possible. We look forward to extending our efforts in commercial space to include commercial crew by 2017 and to more significant milestones this year on our journey to Mars.”
