“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 arrived SpaceX 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.

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 rocket landing and recovery attempt was a secondary objective of SpaceX, that immediately followed the spectacular nighttime blastoff of the Falcon 9 on Jan. 10 carrying the SpaceX Dragon cargo freighter spacecraft on a critical resupply mission for NASA bound for the space station.

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.

I replied; “It was a 99% success” and more …..

“Am super proud of my crew for making huge strides towards reusability on this mission. You guys rock!” Musk declared in a later tweet.

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.

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.

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.

Note: This breaking news story is being updated. Check back frequently for updates.

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.

SpaceX also had a secondary objective of recovering the Falcon 9 booster’s first stage via an unprecedented precision guided landing on an ocean-going “drone.”

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.

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.”

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.

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 exploded unexpectedly after launch from NASA Wallops, VA, on Oct. 28, 2014.

The oft delayed launch of the SpaceX Falcon 9 rocket on the CRS-5 cargo resupply mission for NASA to the International Space Station (ISS) has been reset to Saturday, Jan. 10.

Liftoff is currently targeted for 4:47 a.m. EST Saturday, Jan. 10, from Space Launch Complex 40 at Cape Canaveral Air Force Station in Florida following a postponement from Friday, Jan. 9.

The launch was unexpectedly scrubbed with one minute, 21 seconds left on the countdown clock for technical reasons earlier this week just prior to the targeted blastoff time of 6:20 a.m. EST on Tuesday, Jan. 6.

A thrust vector control actuator for the Falcon 9’s second stage failed to perform as expected, resulting in a launch abort, said NASA.

NASA and SpaceX decided to take another day to fully evaluate the issue and ensure a launch success.

The launch will be the first Falcon 9 liftoff for 2015.

The overnight launch should put on a spectacular sky show for spectators along the Florida space coast.

There is only an instantaneous launch window available, meaning that the blastoff must proceed at that exact instant. Any delays due to technical issues or weather would force a scrub until at least Tuesday, Jan. 13.

Overall, CRS-5 is the company’s fifth commercial resupply services mission to the International Space Station.

In additional to being a critical cargo mission required to keep the space station stocked with provisions for the crew and research experiments, the mission features a history making attempt to recover the first stage of the Falcon 9 rocket.

The rocket recovery and landing attempt is a key step towards carrying out SpaceX CEO Elon Musk’s bold vision of rocket reusability.

Towards that end, SpaceX dispatched the “autonomous spaceport drone ship” sailing at sea towards a point where Musk hopes it will serve as an ocean going landing platform for the precision landing of his firm’s Falcon 9 rocket after it concludes its launch phase to the ISS.

The “autonomous spaceport drone ship” departed the port of Jacksonville, FL, on Saturday, Jan. 3, heading to a point somewhere around 200 to 250 miles or so off the US East coast in a northeasterly direction coinciding with the flight path of the rocket.

However, the absolute overriding goal of the mission is to safely deliver NASA’s contracted cargo to the ISS, emphasized Hans Koenigsmann, VP of Mission Assurance, SpaceX, at a media briefing on Jan. 5 at the Kennedy Space Center.

Landing on the off-shore barge is just a secondary objective of SpaceX, not NASA, he repeated several times.

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.

When it comes to science and space exploration, you have to get accustomed to a mix of success and failure.

If you’re wise you learn from failure and turn adversity around into a future success.

Such is the case for the resilient student scientists who learned a hard lesson of life at a young age when the space science experiments they poured their hearts and souls into for the chance of a lifetime to launch research investigations aboard the Antares rocket bound for the International Space Station (ISS) on the Orb-3 mission, incomprehensibly exploded in flames before their eyes on Oct. 28, 2014.

Those student researchers from across America are being given a second chance and will have their reconstituted experiments re-flown on the impending SpaceX CRS-5 mission launch, thanks to the tireless efforts of NASA, NanoRacks, CASIS, SpaceX and the Student Spaceflight Experiments Program (SSEP) which runs the program.

The SpaceX CRS-5 launch to the ISS on the Falcon 9 rocket planned for this morning, Jan. 6, was scrubbed with a minute to go for technical reasons and has been reset to no earlier than Jan. 9.

The experiments are known collectively as the ‘Yankee Clipper’ mission.

Antares Orb-3 was destroyed shortly after the exhilarating blastoff from NASA’s Wallops Flight Facility on the Virginia shore.

Everything aboard the Orbital Sciences Antares rocket and ‘the SS Deke Slayton’ Cygnus cargo freighter was lost, including all the NASA supplies and research as well as the student investigations.

“The student program represents 18 experiments flying as the Yankee Clipper,” said Dr. Jeff Goldstein, in an interview with Universe Today at NASA Wallops prior to the Antares launch. Goldstein is director of the National Center for Earth and Space Science Education, which oversees SSEP in partnership with NanoRacks LLC.

“Altogether 8 communities sent delegations. 41 student researchers were at NASA Wallops for the launch and SSEP media briefing.”

“The 18 experiments flying as the SSEP Yankee Clipper payload reflect the 18 communities participating in Mission 6 to ISS.”

“The communities represent grade 5 to 16 schools from all across America including Washington, DC; Kalamazoo, MI; Berkeley Heights and Ocean City, NJ; Colleton County and North Charleston, SC, and Knox County and Somerville, TN.”

Goldstein explains that within days of the launch failure, efforts were in progress to re-fly the experiments.

“Failure happens in science and what we do in the face of that failure defines who we are,” said Goldstein, “NASA and NanoRacks moved mountains to get us on the next launch, SpaceX CRS-5. We faced an insanely tight turnaround, but all the student teams stepped up to the plate.”

Even the NASA Administrator Charles Bolden lauded the students efforts and perseverance!

“I try to teach students, when I speak to them, not to be afraid of failure. An elementary school student once told me, when I asked for a definition of success, that ‘success is taking failure and turning it inside out.’ It is important that we rebound, learn from these events and try again — and that’s a great lesson for students,” said NASA Administrator Bolden.

“I am delighted that most of the students will get to see their investigations re-flown on the SpaceX mission. Perseverance is a critical skill in science and the space business.”

Virtually all of the experiments have been reconstituted to fly on the CRS-5 mission, also known as SpaceX-5.

“17 of the 18 student experiments lost on Orb-3 on October 28 are re-flying on SpaceX-5. These experiments comprise the reconstituted Student Spaceflight Experiments Program (SSEP) Yankee Clipper II payload for SSEP Mission 6 to ISS,” noted Goldstein.

“This shows the resilience of the federal-private partnership in commercial space, and of the commitment by our next generation of scientists and engineers.”

The wide range of experiments include microgravity investigations on how fluids act and form into crystals in the absence of gravity crystal growth, mosquito larvae development, milk expiration, baby bloodsuckers, development of Chrysanthemum and soybean seeds and Chia plants, effect of yeast cell division and implications for human cancer cells, and an examination of hydroponics.

That dark day in October witnessed by the students, Goldstein, myself as a fellow scientist, and others is something we will never forget. We all chose to learn from the failure and move forward to greater accomplishments.

Don’t surrender to failure. And don’t give in to the ‘Do Nothing – Can’t Do’ crowd so prevalent today.

Remember what President Kennedy said during his address at Rice University on September 12, 1962:

“We choose to go to the moon in this decade and do the other things, not because they are easy, but because they are hard.”

SpaceX is on track to rollout their Falcon 9 rocket carrying the Dragon cargo freighter this evening, Monday, Jan, 5, 2015 to launch pad 40 on a mission bound for the International Space Station (ISS) to deliver critical supplies.

The Dragon CRS-5 mission is slated to blast off at 6:20 a.m. EST, Tuesday, Jan. 6, 2015, atop the SpaceX Falcon 9 rocket from Space Launch Complex 40 at Cape Canaveral Air Force Station in Florida.

The predawn launch should put on a spectacular sky show for spectators along the Florida space coast.

There is only an instantaneous launch window available, meaning that the blastoff must proceed at that exact instant. Any delays due to technical issues or weather would force a scrub until at least Friday, Jan. 9.

The launch has already been postponed several times, most recently from Dec. 19, 2014 when a static fire test of the first stage engines on Dec. 17 shut down prematurely.

A second static fire test of the SpaceX Falcon 9 successfully went the full duration of approximately 3 seconds and cleared the path for a liftoff attempt after the Christmas holidays.

The delay allowed the teams to recoup and recover and enjoy the festive holiday season.

“It was a good decision to postpone the launch until after the holidays,” said Hans Koenigsmann, VP of Mission Assurance, SpaceX, at a media briefing today at the Kennedy Space Center (KSC).

Following the catastrophic failure of the Orbital Sciences Antares rocket and Cygnus cargo freighter on Oct. 28 from NASA’s Wallops Flight Facility in Virginia, officials have been prudently cautious to ensure that all measures were carefully rechecked to maximize the possibilities of a launch success.

CRS-5 marks the company’s fifth 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

The weather odds have improved to 70% GO from 60% GO reported Major Perry Sweat, 45th Weather Squadron rep, USAF, at the briefing today at the Kennedy Space Center.

A frontal boundary has settled in over Central Florida. This front and its associated cloudiness will be very slow to move south of the Space Coast. With the clouds only slowly eroding overhead, the primary weather concern remains thick clouds, according to Sweat.

The unmanned cargo freighter is loaded with more than 5108 pounds (2317 kg) of scientific experiments, technology demonstrations, crew supplies, spare parts, food, water, clothing and assorted research gear for the space station.

The Dragon research experiments will support over 256 science and research investigations for the six person space station crews on Expeditions 42 and 43.

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.

Assuming all goes well, Dragon will rendezvous at the ISS on Thursday, Jan. 8, for grappling and berthing by the ISS astronauts maneuvering the 57 foot-long (17 meter-long) Canadian built robotic arm.

The SpaceX CRS-5 launch is the first cargo launch to the ISS since the doomed Orbital Sciences Antares/Cygnus launch ended in catastrophe on Oct. 28.

With Antares launches on indefinite hold, the US supply train to the ISS is now wholly dependent on SpaceX.

Orbital Sciences has now contracted United Launch Alliance
(ULA) to launch the firms Cygnus cargo freighter to the ISS by late 2015 on an Atlas V rocket.

A secondary objective of SpaceX is to attempt to recover the Falcon 9 first stage on an off shore barge.

KENNEDY SPACE CENTER, FL – To ensure the highest possibility of success for the launch of a critical resupply mission to the International Space Station (ISS), SpaceX has announced the successful completion of a second static fire test of the first stage propulsion system of the firms commercial Falcon 9 rocket on Dec. 19.

The successful engine test clears the path towards a liftoff now rescheduled to early January 2015.

The launch of the Falcon 9 had been slated for Dec. 19, but NASA and SpaceX decided just 1 day before liftoff on Dec. 18 to postpone the launch of the CRS-5 resupply mission into the new year, when the first static fire test failed to run for its full duration of approximately three seconds.

“SpaceX completed a successful static fire test of the Falcon 9 rocket [on Dec. 19] in advance of the CRS-5 mission for NASA,” said SpaceX in a statement.

The second test was done because the first test of the Merlin 1D engines did not run for its full duration of about three seconds.

“While the Dec. 17 static fire test accomplished nearly all of our goals, the test did not run the full duration, ”SpaceX spokesman John Taylor confirmed to Universe Today.

“The data suggests we could push forward without a second attempt, but out of an abundance of caution, we are opting to execute a second static fire test prior to launch.”

Both tests were conducted at Space Launch Complex 40 at Cape Canaveral Air Force Station in Florida.

“We opted to execute a second test,” noted SpaceX.

The SpaceX Falcon 9 rocket carrying the Dragon cargo freighter had been slated to liftoff on Dec. 19 on its next unmanned cargo run dubbed CRS-5 to the ISS under NASA’s Commercial Resupply Services (CRS) contract.

Following the catastrophic failure of the Orbital Sciences Antares rocket and Cygnus cargo freighter on Oct 28 from NASA’s Wallops Flight Facility in Virginia, officials are being prudently cautious to ensure that all measures are being carefully rechecked to maximize the possibilities of a launch success.

The new launch date for CRS-5 is now set for no earlier than Jan. 6, 2015

“Given the extra time needed for data review and testing, coupled with the limited launch date availability due to the holidays and other restrictions, our earliest launch opportunity is now January 6 with January 7 as a backup,” said SpaceX.

The unmanned cargo freighter is loaded with more than 3,700 pounds of scientific experiments, technology demonstrations, crew supplies, spare parts, food, water, clothing and assorted research gear.

The Dragon research experiments will support over 256 science and research investigations for the six person space station crews on Expeditions 42 and 43.

CRS-5 marks the company’s fifth 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 ISS during a dozen Dragon cargo spacecraft flights through 2016.

Among the other mission goals, SpaceX is planning a daring and bold attempt to propulsively land and recover the first stage on an ocean going platform called the “autonomous spaceport drone ship.”

KENNEDY SPACE CENTER, FL – Due to technical problems encountered during a hot fire test of the first stage engines this week with the SpaceX Falcon 9 rocket, the planned Dec. 19 launch of the commercial rocket and NASA contracted Dragon cargo freighter to the International Space Station (ISS) on a critical resupply mission has been postponed a few weeks into the new year to Jan. 6 at the earliest “out of an abundance of caution,” SpaceX officials told Universe Today.

Prior to every launch, SpaceX performs an internally required full countdown dress rehearsal and hot fire test of the first stage propulsion systems.

The hot fire test attempted on Tuesday “did not run for its full duration” of about three seconds, SpaceX spokesman John Taylor confirmed to me.

Therefore SpaceX and NASA managers decided to postpone the launch in order to run another static fire test.

“We are opting to execute a second static fire test prior to launch,” Taylor said.

In light of the catastrophic failure of the Orbital Sciences Antares rocket and Cygnus cargo freighter, everything must be done to ensure a launch success.

Due to the large amount of work required to test and analyze all rocket systems and the impending Christmas holidays, the earliest opportunity to launch is Jan. 6.

The SpaceX Falcon 9 rocket carrying the Dragon cargo freighter had been slated to liftoff on its next unmanned cargo run dubbed CRS-5 to the ISS under NASA’s Commercial Resupply Services (CRS) contract.

Here is the full update from SpaceX.

“While the recent static fire test accomplished nearly all of our goals, the test did not run the full duration. The data suggests we could push forward without a second attempt, but out of an abundance of caution, we are opting to execute a second static fire test prior to launch.”

“Given the extra time needed for data review and testing, coupled with the limited launch date availability due to the holidays and other restrictions, our earliest launch opportunity is now Jan. 6 with Jan. 7 as a backup.

“The ISS orbits through a high beta angle period a few times a year. This is where the angle between the ISS orbital plane and the sun is high, resulting in the ISS’ being in almost constant sunlight for a 10 day period.

“During this time, there are thermal and operational constraints that prohibit Dragon from being allowed to berth with the ISS. This high beta period runs from 12/28/14-1/7/15”

“Note that for a launch on 1/6 , Dragon berths on 1/8.”

“Both Falcon 9 and Dragon remain in good health, and our teams are looking forward to launch just after the New Year.”

SpaceX Falcon 9 Rocket to Attempt Daring Ocean Platform Landing with Next Launch

KENNEDY SPACE CENTER, FL – In a key test of rocket reusability, SpaceX will attempt a daring landing of their Falcon 9 first stage rocket on an ocean platform known as the “autonomous spaceport drone ship” following the planned Friday, Dec. 19, blastoff on a high stakes mission to the International Space Station (ISS).

The SpaceX Falcon 9 rocket carrying the Dragon cargo freighter is slated to liftoff on its next unmanned cargo run, dubbed CRS-5, to the ISS under NASA’s Commercial Resupply Services (CRS) contract. In a late development, there is a possibility the launch could be postponed to January 2015.

The instantaneous launch window for the Falcon 9/Dragon is slated for 1:20 p.m from Space Launch Complex 40 at Cape Canaveral Air Force Station in Florida.

As the Dragon proceeds to orbit, SpaceX engineers will attempt to recover the Falcon 9 first stage via a precision landing for the first time “on a custom-built ocean platform known as the autonomous spaceport drone ship,” according to a SpaceX statement.

“While SpaceX has already demonstrated two successful soft water landings, executing a precision landing on an unanchored ocean platform is significantly more challenging.”

SpaceX rates the chances of success at “perhaps 50% at best.”

Of course since this has never been attempted before, tons of planning is involved and lots can go wrong.

But this is space exploration, and it’s not for the meek and mild.

It’s time to go boldly where no one has gone before and expand the envelope if we hope to achieve great things.

The 14 story Falcon 9 will be zooming upwards at 1300 m/s (nearly 1 mi/s). Engineers will then relight the Merlin 1D first stage engines to stabilize and lower the rocket.

Four hypersonic grid fins had been added to the first stage and placed in an X-wing configuration. They will be deployed only during the reentry attempt and will be used to roll, pitch, and yaw the rocket in concert with gimballing of the engines.

Here’s a description from SpaceX:

“To help stabilize the stage and to reduce its speed, SpaceX relights the engines for a series of three burns. The first burn—the boostback burn—adjusts the impact point of the vehicle and is followed by the supersonic retro propulsion burn that, along with the drag of the atmosphere, slows the vehicle’s speed from 1300 m/s to about 250 m/s. The final burn is the landing burn, during which the legs deploy and the vehicle’s speed is further.”

“To complicate matters further, the landing site is limited in size and not entirely stationary. The autonomous spaceport drone ship is 300 by 100 feet, with wings that extend its width to 170 feet. While that may sound huge at first, to a Falcon 9 first stage coming from space, it seems very small. The legspan of the Falcon 9 first stage is about 70 feet and while the ship is equipped with powerful thrusters to help it stay in place, it is not actually anchored, so finding the bullseye becomes particularly tricky. During previous attempts, we could only expect a landing accuracy of within 10km. For this attempt, we’re targeting a landing accuracy of within 10 meters.”
