An actuator that was “behaving strangely” on the SpaceX Falcon 9’s upper stage caused a last minute scrub for Tuesday’s attempt to launch a Dragon capsule to the International Space Station, as well as the first try at an historic first stage landing on a floating platform in the Atlantic Ocean.
Need to investigate the upper stage Z actuator. Was behaving strangely. Next launch attempt on Friday at 5am.
SpaceX will try again on Friday, January 9, 2014 at 5:09 a.m. EST. Like today’s attempt, there will be 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 further delays.
This is the commercial space company’s fifth resupply mission to the ISS and the unmanned cargo freighter is loaded with more than 5,108 pounds (2317 kg) of scientific experiments, technology demonstrations, crew supplies, spare parts, food, water, clothing and assorted research gear for the space station.
The “experiment” that has attracted the most attention, however, is the attempt to land the first stage of the two-stage rocket on a floating platform in the Atlantic Ocean, approximately 320 km (200 miles) off the coast of Florida.
This is the first attempt at such a landing. SpaceX has conducted numerous successful soft landing tests on land, and done several touchdowns on the ocean’s surface.
Elon Musk has estimated the odds of success at the landing attempt at about 50% at best.
“It’s an experiment,” said Hans Koenigsmann, VP of Mission Assurance at SpaceX, speaking at a media briefing on Jan. 5 at the Kennedy Space Center. “There’s a certain likelihood that this will not work out right, that something will go wrong.” He also added that the landing on the off shore barge is just a secondary objective of SpaceX, not NASA.
It’s sunrise from space – one of 16 that occur daily as the massive lab complex orbits the Earth about every 90 minutes while traveling swiftly at about 17,500 mph and an altitude of about 250 miles (400 kilometers).
Just stare in amazement at this gorgeous sunrise view of “Our Beautiful Earth” taken earlier today, Jan. 3, 2015, aboard the International Space Station (ISS) by crewmate and NASA astronaut Barry “Butch” Wilmore.
And smack dab in the middle is the Canadian-built robotic arm that will soon snatch a soaring Dragon!
Wilmore is the commander of the ISS Expedition 42 crew of six astronauts and cosmonauts hailing from three nations: America, Russia and Italy.
He is accompanied by astronauts Terry Virts from NASA and Samantha Cristoforetti from the European Space Agency (ESA) as well as by cosmonauts Aleksandr Samokutyayev, Yelena Serova, and Anton Shkaplerov from Russia.
All told the crew of four men and two women see 16 sunrises and 16 sunsets each day. During the daylight periods, temperatures reach 200 ºC, while temperatures plunge drastically during the night periods to -200 ºC.
Here’s another beautiful ISS sunset view captured on Christmas by Terry Virts:
Virts tweeted the picture and wrote: “Sunrise on Christmas morning – better than any present I could ask for!!!!”
Another treasure from Virts shows the many splendid glorious colors of Earth seen from space but not from the ground:
“In space you see intense colors, shades of blue that I’d never seen before,” says Virts from his social media accounts (http://instagram.com/astro_terry/) (http://instagram.com/iss).
“It’s been said a thousand times but it’s true: There are no borders that you can see from space, just one beautiful planet,” he says. “If everyone saw the Earth through that lens I think it would be a much better place.”
And many of the crews best images are taken from or of the 7 windowed Cupola.
Here’s an ultra cool shot of Butch waving Hi!
And they all eagerly await the launch and arrival of a Dragon! Indeed it’s the SpaceX cargo Dragon currently slated for liftoff in three days on Tuesday, Jan. 6.
Weather odds are currently 60% favorable for launch of the unmanned space station resupply ship on the SpaceX CRS-5 mission.
The launch was postponed from Dec. 19 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 went the full duration of approximately 3 seconds and cleared the path for a liftoff attempt after the Christmas holidays.
CRS-5 is slated to blast off at 6:20 a.m. EST Tuesday, Jan. 6, 2015, atop a SpaceX Falcon 9 rocket from Cape Canaveral Air Force Station in Florida.
NASA Television live launch coverage begins at 5 a.m. EST.
Assuming all goes well, Dragon will rendezvous at the ISS on Thursday, Jan. 8, for grappling and berthing by the astronauts maneuvering the 57 foot-long (22 m) Canadian built robotic arm.
Remember that you can always try and catch of glimpse of the ISS flying overhead by checking NASA’s Spot the Station website with a complete list of locations.
And don’t forget to catch up on the Christmas holiday and New Year’s 2015 imagery and festivities from the station crews in my recent stories – here, here and here.

The current six person crew includes astronauts and cosmonauts from three nations – America, Russia, and Italy – and the four men and two women are celebrating New Year’s 2015 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 ISS has been continuously occupied by humans for 15 years. And they are joined by Robonaut 2 who recently got legs.
Terry Virts and Samantha Cristoforetti have been especially prolific in picture taking and posting to social media for us all to enjoy the view while speeding merrily along at 17,500 mph from an altitude of about 250 miles (400 kilometers) above Earth.
Here’s a special New Year video greeting from Wilmore and Virts:

“Happy New Year from the International Space Station!” said Wilmore.
“We figure that we will be over midnight somewhere on the Earth on New Year’s for 16 times throughout this day. So we plan to celebrate New Year’s 16 times with our comrades and our people down on Earth.”
“We wish everybody a happy, healthy, and prosperous 2015 as we get the awesome privilege of celebrating New Year’s here on the space station with our six station crewmates,” added Virts!
“We’ll enjoy our 16 New Year’s celebrations here.”
They plan to celebrate the dawn of 2015 with fruit juice toasts, NASA reports.
The year 2015 starts officially for the station crew at midnight by the Universal Time Clock (UTC), also known as Greenwich Mean Time (GMT), in London, or at 7 p.m. EST Dec. 31.
New Year’s Day 2015 is a day off for the crew.
And I’m certain they’ll be gazing out the windows capturing more views of “Our Beautiful Earth!”
And don’t forget to catch up on the Christmas holiday imagery and festivities from the station crews in my recent stories – here and here.
Be sure to remember that you can always try and catch of glimpse of the ISS flying overhead by checking NASA’s Spot the Station website with a complete list of locations.
Meanwhile the crew continues science operations and preparations for next week’s arrival of the next unmanned space station resupply ship on the SpaceX CRS-5 mission.
CRS-5 is slated to blast off atop a SpaceX Falcon 9 rocket on Jan. 6 from Cape Canaveral Air Force Station in Florida.

This has been on my bucket list for a while, but I’ve never had the opportunity to witness it myself: seeing the International Space Station transit the Moon. And now thanks to my friend Gadi Eidelheit, I want to see it for myself even more! He captured video and imagery of the ISS scooting in front of the Moon, from Ganot, Israel.
“This was just about 10km from my house!” Gadi told me via email. “I used a Canon 700d with Sigma 18-250 for the first clip and Canon sx50HS for the second clip (maximum zoom which equivalent to 1200mm). To find the best place I used Heavens-Above and a little trial and error! I just choose different locations near my home until I found the correct spot.”
For the first part of the video you need to look closely, as the transit happens quite quickly. But then Gadi slows it down, and later zooms in on the action. It still happens quite quickly but it’s very fun to see.
Gadi is an amateur astronomer and blogger who always has interesting things to post on social media or on his blog. You’ve really got me motivated now, Gadi!!

ESA astronaut Alexander Gerst from Germany who recently returned from a six month voyage to the International Space Station (ISS) has a special Christmas gift for all – a stunning six-minute timelapse compilation of his favorite images of Earth taken during his “Blue Dot” mission in 2014.
“A 4K timelapse showing our planet in motion, from my favourite Earth images taken during the Blue Dot mission,” wrote Gerst in connection with his spectacular timelapse video released to coincide with Christmastime.
“I wish all of you a merry Christmas! It was a wild year for me, thanks for joining me on this fascinating journey!” said Gerst in English.
“Wünsche euch allen fröhliche Weihnachten! War ein wildes Jahr für mich, vielen Dank, dass ihr mit dabei wart!” said Gerst in German.
You can watch the Earth roll by through Gerst’s perspective in this six-minute timelapse video combining over 12,500 images taken during his six-month mission aboard the ISS that shows the best our beautiful planet has to offer.
“Marvel at the auroras, sunrises, clouds, stars, oceans, the Milky Way, the International Space Station, lightning, cities at night, spacecraft and the thin band of atmosphere that protects us from space,” according to the video’s description.
Gerst would often would set cameras to automatically take pictures at regular intervals while doing his science research or preparing for the docking of other spacecraft at the ISS in order to get the timelapse effect shown in the video.
The robotic arm capture and berthing of the SpaceX Dragon cargo ship and the release of the Orbital Sciences Cygnus cargo freighter are particularly magnificent in a rarely seen timelapse glimpse of visiting vehicles that are absolutely essential to keeping the station afloat, stocked, and humming with research activities.
Gerst served aboard the ISS between May and November this year as a member of the Expedition 40 and 41 crews.
Gerst launched to the ISS on his rookie space flight on May 28, 2014, aboard the Russian Soyuz TMA-13M capsule along with Russian cosmonaut Maxim Suraev and NASA astronaut Reid Wiseman.
They joined the three station flyers already aboard – cosmonauts Alexander Skvortsov & Oleg Artemyev, and astronaut Steve Swanson – to restore the station crew complement to six.
Gerst and Wiseman became well known and regarded for their prolific and expertly crafted photography skills.
They returned to Earth safely on Nov. 10, 2014, with a soft landing on the Kazakh steppes.
Alex is Germany’s third astronaut to visit the ISS. He conducted a spacewalk with Wiseman on Oct. 7 while aboard. He is trained as a geophysicist and a volcanologist.

There is a long tradition of Christmas greetings from spacefarers soaring around the High Frontier and this year is no exception!
The Expedition 42 crew currently serving aboard the International Space Station has decorated the station for the Christmas 2014 holiday season and send their greetings to all the people of Earth from about 240 miles (400 km) above!
“Merry Christmas from the International Space Station!” said astronauts Barry Wilmore and Terry Virts of NASA and Samantha Cristoforetti of ESA, who posed for the group shot above.
“It’s beginning to look like Christmas on the International Space Station,” said NASA in holiday blog update.
“The stockings are out, the tree is up and the station residents continue advanced space research to benefit life on Earth and in space.”
And the six person crew including a trio of Russian cosmonauts, Aleksandr Samokutyayev, Yelena Serova, and Anton Shkaplerov who celebrate Russian Orthodox Christmas, are certainly hoping for and encouraging a visit from Santa. Terry Virts even tweeted a picture of the special space style milk and cookies awaiting Santa and his Reindeer for the imminent arrival!
“No chimney up here- so I left powdered milk and freeze dried cookies in the airlock. Fingers crossed,” tweeted Virts.
And here’s a special Christmas video greeting from Wilmore and Virts:

“We wish you all a Merry Christmas and Happy New Year. Christmas for us is a time of worship. It’s a time that we think back to the birth of what we consider our Lord. And we do that in our homes and we plan to do the same thing up here and take just a little bit of time just to reflect on those topics and, also, just as the Wise Men gave gifts, we have a couple of gifts,” Wilmore says in the video.
“It’s such an honor and so much fun to be able to celebrate Christmas up here. This is definitely a Christmas that we’ll remember, getting a chance to see the beautiful Earth,” added Virts. “Have fun with your family. Merry Christmas!”
And you can send a holiday tweet to the crew – here:
Meanwhile the crew is still hard at work doing science and preparing for the next space station resupply mission launch by SpaceX from Cape Canaveral, Florida.
A SpaceX Falcon 9 rocket is now set to blastoff on Jan. 6, 2015 carrying the Dragon cargo freighter on the CRS-5 mission bound for the ISS.
The launch was postponed from Dec. 19 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 went the full duration and cleared the path for the Jan. 6 liftoff attempt.
Among the science studies ongoing according to NASA are:
“Behavioral testing for the Neuromapping study to assess changes in a crew member’s perception, motor control, memory and attention during a six-month space mission. Results will help physicians understand brain structure and function changes in space, how a crew member adapts to returning to Earth and develop effective countermeasures.”
“Another study is observing why human skin ages at a quicker rate in space than on Earth. The Skin B experiment will provide scientists a model to study the aging of other human organs and help future crew members prepare for long-term missions beyond low-Earth orbit.”
Merry Christmas to All!
Stay tuned here for Ken’s continuing Earth and planetary science and human spaceflight news.
NASA and SpaceX are now targeting Dec. 19 as the launch date for the next unmanned cargo run to the International Space Station (ISS) under NASA’s Commercial Resupply Services contract.
The fifth SpaceX cargo mission was postponed from Dec. 16 to Dec. 19 to “allow SpaceX to take extra time to ensure they do everything possible on the ground to prepare for a successful launch,” according to a statement from NASA.
The Dragon spacecraft will launch atop a SpaceX Falcon 9 rocket from Space Launch Complex 40 at Cape Canaveral Air Force Station in Florida.
Both the Falcon 9 rocket and its Dragon spacecraft are in good health, according to NASA.
The mission dubbed SpaceX CRS-5 is slated for liftoff at 1:20 p.m.
An on time liftoff will result in a rendezvous with the ISS on Sunday. The crew would grapple the Dragon with the stations 57 foot long robotic arm at about 6 a.m.
US astronaut and station commander Barry Wilmore will operate the Canadarm2 to capture the SpaceX Dragon when it arrives Sunday morning. ESA astronaut Samantha Cristoforetti will assist Wilmore working at a robotics workstation inside the domed Cupola module during the commercial craft’s approach and rendezvous.
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.
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.
A secondary objective of SpaceX is to attempt to recover the Falcon 9 first stage on an off shore barge.
The SpaceX CRS-4 mission to the ISS concluded with a successful splashdown on Oct 25 after a month long stay.
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 United Launch Alliance Altas V 401 rocket like that shown here will launch the next Orbital Sciences Cygnus cargo ship to the space station in place of the Antares rocket. NASA’s Mars-bound MAVEN spacecraft launches atop Atlas V booster at 1:28 p.m. EST from Space Launch Complex 41 at Cape Canaveral Air Force Station on Nov. 18, 2013.

Following the catastrophic Oct. 28 failure of an Orbital Sciences Corporation Antares rocket on a critical resupply mission to the space station for NASA, the company is seeking to quickly make up the loss to NASA by announcing the selection of the venerable Atlas V rocket built by United Launch Alliance to launch Orbital’s next Cygnus cargo ship to the orbital science lab.
Orbital and ULA signed a contract to launch at least one, and up to two, Cygnus cargo missions to the International Space Station (ISS) under NASA’s Commercial Resupply Services (CRS) program.
The first Cygnus mission would liftoff sometime late in the fourth quarter of 2015 aboard an Atlas V 401 vehicle from Space Launch Complex 41 (SLC-41) at Cape Canaveral Air Force Station in Florida.
Given that ULA’s full launch manifest was fairly full for the next 18 months, Orbital is fortunate to have arranged one or two available launch slots so quickly in the wake of the Antares launch disaster.
“Orbital is pleased to partner with ULA for these important cargo missions to the International Space Station,” said Frank Culbertson, Orbital executive vice president and general manager of its Advanced Programs Group.
“ULA’s ability to integrate and launch missions on relatively short notice demonstrates ULA’s manifest flexibility and responsiveness to customer launch needs.”
Orbital also stated that there will be “no cost increase to the space agency” by utilizing the Atlas V as an interim launcher.
If necessary, a second Cygnus would be launched by the Atlas V in 2016.
The 401 version of the Atlas uses a 4 meter diameter payload fairing, no solid rocket boosters strapped on to the first stage, and a single-engine Centaur upper stage.
Orbital had been evaluating at least three different potential launch providers.
Observers speculated that in addition to ULA, the other possibilities included a SpaceX Falcon 9 or a rocket from the European Space Agency at the Guiana Space Center.
“We could not be more honored that Orbital selected ULA to launch its Cygnus spacecraft,” said Jim Sponnick, vice president, Atlas and Delta Programs.
“This mission was awarded in a highly competitive environment, and we look forward to continuing ULA’s long history of providing reliable, cost-effective launch services for customers.”
The Orbital-3, or Orb-3, mission that ended in disaster on Oct. 28 was to be the third of eight cargo resupply missions to the ISS through 2016 under the NASA Commercial Resupply Services (CRS) contract award valued at $1.9 Billion.
The highly anticipated launch of the Antares rocket on Oct 28 suddenly went awry when one of the Soviet-era first stage engines unexpectedly exploded and cascaded into a spectacular aerial fireball just above the launch pad at NASA’s Wallops Flight Facility on the Orb-3 mission to the ISS.
Read my earlier eyewitness accounts at Universe Today.
Orbital was awarded a $1.9 Billion contract with NASA under the CRS program to deliver 20,000 kilograms of research experiments, crew provisions, spare parts, and hardware for the eight ISS flights.
In choosing the Atlas V with a greater lift capacity compared to Antares, Orbital will also be able to significantly increase the cargo mass loaded inside the Cygnus by about 35%.
This may allow Orbital to meet its overall space station payload obligation to NASA in 7 total flights vs. the originally planned 8.
The venerable Atlas V rocket is one of the most reliable and well built rockets in the world.
Indeed the Atlas V has been entrusted to launch many high value missions for NASA and the Defense Department – such as MAVEN, Curiosity, JUNO, TDRSS, and the X-37 B.
MAVEN launched on a similar 401 configuration being planned for Cygnus.
The two-stage Atlas rocket is also being man-rated right now to launch humans to low Earth orbit in the near future.
Orbital is still in the process of deciding on a new first stage propulsion system for Antares’ return to flight planned for perhaps sometime in 2016.

Story and images expanded
NASA WALLOPS FLIGHT FACILITY, VA – Moments after a seemingly glorious liftoff on Oct. 28, 2014, the Orbital Sciences Corp. commercial Antares rocket suffered a catastrophic failure as one of the Soviet-era first stage engines exploded and cascaded into a spectacular aerial fireball just above the launch pad at NASA’s Wallops Flight Facility on the doomed Orb-3 mission to the International Space Station (ISS).
Although I witnessed and photographed the launch failure from the media viewing area on site at NASA Wallops from a distance of about 1.8 miles away, myself and a small group of space journalists working together from Universe Today, AmericaSpace, and Zero-G News had also placed sound activated cameras directly at the launch pad to capture the most spectacular up close views for what we all expected to be a “nominal” launch. Our imagery had been impounded by accident investigators – until being released to us now.
Now in part 2 of this exclusive series of video and photos our team can show you the terrible fate suffered by Antares after its destructive descent and frightening incineration as it was consumed by a hellish inferno.
My time lapse video above clearly shows the explosion and incendiary descent of Antares into a mammoth fireball.
As I reported in Part 1, all of our team’s cameras and image cards were impounded for nearly a month by Orbital’s official and independent Accident Investigation Board (AIB) that was assembled quickly in the aftermath of the Antares launch failure disaster and charged with determining the root cause of the launch failure.
The videos and photos captured on our image cards were used as evidence and scrutinized by the investigators searching for clues as to the cause and have only just been returned to us in the past few days.
One image clearly shows that the south side engine nozzle of the AJ26 first stage engine was intact and had shut down after the initial explosion and during the plummet. Therefore it was the north side engine that blew up and led to the launch failure. See my up close AJ26 engine photo below.
Video Caption: AmericaSpace and Zero-G News video compilation of four cameras surrounding the launch pad to capture liftoff.

Similar launch pad photos taken by NASA and Orbital Sciences cameras have not been publicly released and may not be released for some time to come.
The videos and images collected here are the work of my colleagues Matthew Travis, Elliot Severn, Alex Polimeni, Charles Twine, Jeff Seibert, Mike Barrett, and myself, and show exquisite, heretofore unreleased, views of the explosion, fireball, and wreckage from various positions all around the launch pad.
Our remote cameras were placed all around the Antares pad OA at the Mid-Atlantic Regional Spaceport (MARS) on Wallops Island, VA, and somehow miraculously survived the rocket’s destruction as it plunged to the ground very near and just north of the seaside launch pad.
A turbopump failure in one of the rocket’s Soviet-era first stage engines has been identified as the most likely cause of the Antares’ destruction according to official statements from David Thompson, Orbital’s Chairman and Chief Executive Officer.
The AJ26 engines were originally manufactured some 40 years ago in the then Soviet Union as the NK-33.
They were refurbished and “Americanized” by Aerojet Rocketdyne.
“While still preliminary and subject to change, current evidence strongly suggests that one of the two AJ26 main engines that powered Antares’ first stage failed about 15 seconds after ignition. At this time, we believe the failure likely originated in, or directly affected, the turbopump machinery of this engine, but I want to stress that more analysis will be required to confirm that this finding is correct,” said Thompson.
Overall this was the 5th Antares launch using the AJ26 engines.
Antares was carrying Orbital’s privately developed Cygnus pressurized cargo freighter loaded with nearly 5000 pounds (2200 kg) of science experiments, research instruments, crew provisions, spare parts, spacewalk and computer equipment and gear on a critical resupply mission dubbed Orb-3 bound for the International Space Station (ISS).
It was the heaviest cargo load yet lofted by a Cygnus. Some 800 pounds additional cargo was loaded on board compared to earlier flights. That was enabled by using the more powerful ATK CASTOR 30XL engine to power the second stage for the first time.
The astronauts and cosmonauts depend on a regular supply train from the ISS partners to kept it afloat and productive on a 24/7 basis.
The Orbital-3, or Orb-3, mission was to be the third of eight cargo resupply missions to the ISS through 2016 under the NASA Commercial Resupply Services (CRS) contract award valued at $1.9 Billion.
Orbital Sciences is under contract to deliver 20,000 kilograms of research experiments, crew provisions, spare parts, and hardware for the eight ISS flights.

Barely two months after being launched to the International Space Station (ISS), NASA’s first science payload aimed at conducting Earth science from the station’s exterior has started its ocean wind monitoring operations two months ahead of schedule.
Data from the ISS Rapid Scatterometer, or ISS-RapidScat, payload is now available to the world’s weather and marine forecasting agencies following the successful completion of check out and calibration activities by the mission team.
Indeed it was already producing high quality, usable data following its power-on and activation at the station in late September and has monitored recent tropical cyclones in the Atlantic and Pacific Oceans prior to the end of the current hurricane season.
RapidScat is designed to monitor ocean winds for climate research, weather predictions, and hurricane monitoring for a minimum mission duration of two years.
“RapidScat is a short mission by NASA standards,” said RapidScat Project Scientist Ernesto Rodriguez of JPL.
“Its data will be ready to help support U.S. weather forecasting needs during the tail end of the 2014 hurricane season. The dissemination of these data to the international operational weather and marine forecasting communities ensures that RapidScat’s benefits will be felt throughout the world.”
The 1280 pound (580kilogram) experimental instrument was developed by NASA’s Jet Propulsion Laboratory. It’s a cost-effective replacement to NASA’s former QuikScat satellite.
The $26 million remote sensing instrument uses radar pulses reflected from the ocean’s surface at different angles to calculate the speed and direction of winds over the ocean for the improvement of weather and marine forecasting and hurricane monitoring.
The RapidScat, payload was hauled up to the station as part of the science cargo launched aboard the commercial SpaceX Dragon CRS-4 cargo resupply mission that thundered to space on the company’s Falcon 9 rocket from Space Launch Complex-40 at Cape Canaveral Air Force Station in Florida on Sept. 21.
ISS-RapidScat is NASA’s first research payload aimed at conducting near global Earth science from the station’s exterior and will be augmented with others in coming years.
It was robotically assembled and attached to the exterior of the station’s Columbus module using the station’s robotic arm and DEXTRE manipulator over a two day period on Sept 29 and 30.
Ground controllers at Johnson Space Center intricately maneuvered DEXTRE to pluck RapidScat and its nadir adapter from the unpressurized trunk section of the Dragon cargo ship and attached it to a vacant external mounting platform on the Columbus module holding mechanical and electrical connections.
The nadir adapter orients the instrument to point its antennae at Earth.
The couch sized instrument and adapter together measure about 49 x 46 x 83 inches (124 x 117 x 211 centimeters).
“The initial quality of the RapidScat wind data and the timely availability of products so soon after launch are remarkable,” said Paul Chang, ocean vector winds science team lead at NOAA’s National Environmental Satellite, Data and Information Service (NESDIS)/Center for Satellite Applications and Research (STAR), Silver Spring, Maryland.
“NOAA is looking forward to using RapidScat data to help support marine wind and wave forecasting and warning, and to exploring the unique sampling of the ocean wind fields provided by the space station’s orbit.”
This has been a banner year for NASA’s Earth science missions. At least five missions will be launched to space within a 12 month period, the most new Earth-observing mission launches in one year in more than a decade.
ISS-RapidScat is the third of five NASA Earth science missions scheduled to launch over a year.
NASA has already launched the of the Global Precipitation Measurement (GPM) Core Observatory, a joint mission with the Japan Aerospace Exploration Agency, in February and the Orbiting Carbon Observatory-2 (OCO-2) carbon observatory in July 2014.
