NASA inaugurated a new era of research for the International Space Station (ISS) as an Earth observation platform following the successful installation and activation of the ISS-RapidScat science instrument on the outposts exterior at Europe’s Columbus module.

The ISS Rapid Scatterometer, or 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.

RapidScat is designed to monitor ocean winds for climate research, weather predictions, and hurricane monitoring.

The 1280 pound (580 kilogram) experimental instrument is already collecting its first science data following its recent power-on and activation at the station.

“Its antenna began spinning and it started transmitting and receiving its first winds data on Oct.1,” according to a NASA statement.

The first image from RapidScat was released by NASA on Oct. 6, shown below, and depicts preliminary measurements of global ocean near-surface wind speeds and directions.

The $26 million remote sensing instrument uses radar pulses to observe the speed and direction of winds over the ocean for the improvement of weather forecasting.

“Most satellite missions require weeks or even months to produce data of the quality that we seem to be getting from the first few days of RapidScat,” said RapidScat Project Scientist Ernesto Rodriguez of NASA’s Jet Propulsion Laboratory, Pasadena, California, which built and manages the mission.

“We have been very lucky that within the first days of operations we have already been able to observe a developing tropical cyclone.

“The quality of these data reflect the level of testing and preparation that the team has put in prior to launch,” Rodriguez said in a NASA statement. “It also reflects the quality of the spare QuikScat hardware from which RapidScat was partially assembled.”

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.

Dragon was successfully berthed at the Earth-facing port on the station’s Harmony module on Sept 23, as detailed here.

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 at Earth.

The couch sized instrument and adapter together measure about 49 x 46 x 83 inches (124 x 117 x 211 centimeters).

Engineers are in the midst of a two week check out process that is proceeding normally so far. Another two weeks of calibration work will follow.

Thereafter RapidScat will begin a mission expected to last at least two years, said Steve Volz, associate director for flight programs in the Earth Science Division, NASA Headquarters, Washington, at a prelaunch media briefing at the Kennedy Space Center.

RapidScat is the forerunner of at least five more Earth science observing instruments that will be added to the station by the end of the decade, Volz explained.

The second Earth science instrument, dubbed CATS, could be added by year’s end.

The Cloud-Aerosol Transport System (CATS) is a laser instrument that will measure clouds and the location and distribution of pollution, dust, smoke, and other particulates in the atmosphere.

CATS is slated to launch on the next SpaceX resupply mission, CRS-5, currently targeted to launch from Cape Canaveral, FL, on Dec. 9.

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 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.

Mars isn’t the only place in the Solar System that was busy this week with arriving spacecraft. While NASA’s MAVEN and ISRO’s MOM arrived in orbit around the Red Planet, the International Space Station also welcomed two arriving spacecraft, bringing the total of docked ships at the ISS to five.

Screenshot from NASA TV of the Soyuz-TMA14M arriving with just one solar panel deployed.
Screenshot from NASA TV of the Soyuz-TMA14M arriving with just one solar panel deployed.

Last night, the Expedition 41/42 crew arrived — peeling in on one solar panel on their Soyuz TMA-14M — with the first female cosmonaut to be part of an ISS crew, Elena Serova along with her crewmates cosmonaut Alexander Samokutyaev, and NASA astronaut Barry Wilmore. They took the Soyuz “fast track,” arriving at the station in just under six hours after launch. One of the craft’s solar panels jammed and couldn’t deploy, but the crew docked to Poisk docking compartment without indecent.

The arrival of Wilmore, Samokutyaev and Serova returns the station’s crew complement to six. Already on board are Commander Max Suraev of Roscosmos, Reid Wiseman of NASA and Alexander Gerst of the European Space Agency. They have been aboard the complex since May.

Suraev, Wiseman and Gerst will return home in November. At that time, Wilmore will become commander of the station for Expedition 42, and the remainder of the Expedition 42 crew will arrive in a new Soyuz.

Earlier this week, on September 23, the SpaceX Dragon capsule arrived with over 2.5 tons of science experiments and supplies for the crew.

Also docked to the space station is the Soyuz ship that will take Suraev, Wiseman and Gerst home, a Progress resupply ship and the European ATV-5 supply ship.

There are two more cargo missions targeted to launch to the space station before the end of the year. Orbital Sciences just announced October 20 as the next launch date for their Cygnus commercial space freighter. It will occupy the same Harmony node port as Dragon when it leaves in a few weeks. When Cygnus vacates the Harmony node port, SpaceX CRS-5 will replace it in December.

Commercial SpaceX Dragon Cargo Capsule Arrives at Space Station

After a two day chase through space, a commercial SpaceX Dragon cargo capsule completed its orbital ballet and arrived at the International Space Station (ISS) today, Sept. 23, packed with some 2.5 tons of ground breaking science experiments and supplies for the human crew.

The Dragon CRS-4 resupply freighter rendezvoused with the station early this morning following a carefully choreographed series of thruster firings that brought the vessel to within a capture distance of some 10 meters (32 feet) beneath the massive orbiting outpost.

Expedition 41 crewmember and European Space Agency astronaut Alexander Gerst then maneuvered the station’s 58-foot Canadian built robotic arm. He deftly captured the Dragon at 6:52 a.m. EDT while working at the controls of the robotics workstation in the Cupola module and as the station soared some 260 miles above the Pacific Ocean.

NASA TV live coverage of the rendezvous and grappling process began at 5:00 a.m. EDT with berthing coverage concluding about 9:30 a.m. – http://www.nasa.gov/ntv

NASA astronaut Reid Wiseman assisted Gerst in operating the Canadarm2 from inside the domed, seven windowed Cupola.

Approximately two hours later at 9 a.m. EST, the private SpaceX Dragon was berthed at the Earth-facing port on the stations Harmony module.

The SpaceX Dragon CRS-4 cargo mission thundered to space on the company’s Falcon 9 rocket from Space Launch Complex-40 at Cape Canaveral Air Force Station in Florida at 1:52 a.m. EDT Sunday, Sept. 21, just hours after a deluge of widespread rain showers inundated central Florida. Story here.

CRS-4 marks the company’s fourth 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.

Eight more Dragon cargo missions to the ISS are slated through 2016.

The Dragon spacecraft is loaded with more than 5,000 pounds of science experiments, spare parts, crew provisions, food, clothing and supplies to the six person crews living and working aboard the ISS soaring in low Earth orbit under NASA’s Commercial Resupply Services (CRS) contract.

This mission opens a new era in Earth science for the ISS. Tucked inside the Dragon’s unpressurized trunk section at the rear is the ISS-Rapid Scatterometer.

RapidScat is NASA’s first research payload aimed at conducting Earth science from the station’s exterior. The station’s robot arm will pluck RapidScat out of the trunk and attach it to an Earth-facing point on the exterior trusswork of ESA’s Columbus science module.

The remote sensing instrument will use radar pulses to observe the speed and direction of winds over the ocean for the improvement of weather forecasting.

Dragon also carries the first 3-D printer to space for the first such space based studies ever attempted by the astronaut crews. The printer will remain at the station for at least the next two years.

Also aboard are 20 mice housed in a special rodent habitat, as well as fruit flies.

Dragon will remain docked to the ISS for about a month. Then it will return to Earth via a parachute assisted Pacific Ocean landing off the coast of Baja California. On the return trip, the capsule will be packed with nearly 3,300 pounds (1,486 kg) of cargo, science samples, and computer and vehicle hardware for engineering checks.

The next SpaceX unmanned resupply mission is set to launch in early December on the CRS-5 flight.

KENNEDY SPACE CENTER, FL – SpaceX is on the cusp of launching the company’s fourth commercial resupply Dragon spacecraft mission to the International Space Station (ISS) shortly after midnight, Saturday, Sept. 20, 2014, continuing a rapid fire launch pace and carrying NASA’s first research payload – RapidScat – aimed at conducting Earth science from the stations exterior.

Final preparations for the launch are underway right now at the Cape Canaveral launch pad with the stowage of sensitive late load items including a specially designed rodent habitat housing 20 mice.

Update 20 Sept: Poor weather scrubs launch to Sept. 21 at 1:52 a.m.

Fueling of the two stage rocket with liquid oxygen and kerosene propellants commences in the evening prior to launch.

If all goes well, Saturday’s launch of a SpaceX Falcon 9 rocket would be the second in less than two weeks, and the fourth over the past ten weeks. The last Falcon 9 successfully launched the AsiaSat 6 commercial telecom satellite on Sept. 7 – detailed here.

“We are ready to go,” said Hans Koenigsmann, SpaceX vice president of mission assurance, at a media briefing at the Kennedy Space Center today, Sept. 19.

Liftoff of the SpaceX Falcon 9 rocket on the CRS-4 mission bound for the ISS is targeted for an instantaneous window at 2:14 a.m. EDT from Space Launch Complex 40 at Cape Canaveral Air Force Station in Florida at the moment Earth’s rotation puts Cape Canaveral in the flight path of the ISS.

The weather forecast is marginal at 50/50 with rain showers and thick clouds as the primary concerns currently impacting the launch site.

The Dragon spacecraft is loaded with more than 5,000 pounds of science experiments, spare parts, crew provisions, food, clothing and supplies to the six person crews living and working aboard the ISS soaring in low Earth orbit under NASA’s Commercial Resupply Services (CRS) contract.

The CRS-4 missions marks the start of a new era in Earth science. The truck of the Dragon is loaded Dragon with the $30 Million ISS-Rapid Scatterometer to monitor ocean surface wind speed and direction.

RapidScat is NASA’s first research payload aimed at conducting Earth science from the stations exterior. The stations robot arm will pluck RapidScat out of the truck and attach it to an Earth-facing point on the exterior trusswork of ESA’s Columbus science module.

Dragon will also carry the first 3-D printer to space for studies by the astronaut crews over at least two years.

The science experiments and technology demonstrations alone amount too over 1644 pounds (746 kg) and will support 255 science and research investigations that will occur during the station’s Expeditions 41 and 42 for US investigations as well as for JAXA and ESA.

“This flight shows the breadth of ISS as a research platform, and we’re seeing the maturity of ISS for that,” NASA Chief Scientist Ellen Stofan said during a prelaunch news conference held today, Friday, Sept. 19 at NASA’s Kennedy Space Center.

After a two day chase, Dragon will be grappled and berth at an Earth-facing port on the stations Harmony module.

The Space CRS-4 mission marks the company’s fourth 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.

Story updated[/caption]

The 30 day flight of the SpaceX-3 Dragon commercial cargo freighter loaded with a huge cache of precious NASA science experiments including a freezer packed with research samples ended today with a spectacular departure from the orbiting lab complex soaring some 266 miles (428 km) above Earth.

Update 3:05 PM EDT May 18: SpaceX confirms successful splashdown at 3:05 p.m. EDT today.

“Splashdown is confirmed!! Welcome home, Dragon!”

Robotics officers at Mission Control at NASA’s Johnson Space Center detached Dragon from the Earth-facing port of the Harmony module at 8 a.m. EDT (1300 GMT) this morning, Sunday, May 18, 2014 using the stations Canadian-built robotic arm.

Engineers had earlier unbolted all 16 hooks and latches firmly connecting the vehicle to the station in preparation.

NASA astronaut Steve Swanson then commanded the gum dropped shaped Dragon capsule’s release from Canadarm2 as planned at 9:26 a.m. EDT (1326 GMT) while the pair were flying majestically over southern Australia.

The undocking operation was shown live on NASA TV.

Swanson was assisted by Russian cosmonaut Alexander Skvortsov as the US- Russian team were working together inside the domed Cupola module.

Following the cargo ships release by the 57 foot long arms grappling snares, Swanson carefully maneuvered the arm back and away from Dragon as it moved ever so slowly in free drift mode.

It was already four feet distant within three minutes of release.

Three departure burns by the Dragon’s Draco maneuvering thrusters followed quickly in succession and occurred precisely on time at 9:29, 9:30 and 9:38 a.m. EST.

Dragon exited the 200 meter wide keep out zone – an imaginary bubble around the station with highly restricted access – at the conclusion of the 3rd departure burn.

“The Dragon mission went very well. It was very nice to have a vehicle take science equipment to the station, and maybe some day even humans,” Swanson radioed after the safe and successful departure was completed.

“Thanks to everyone who worked on the Dragon mission.”

The private SpaceX Dragon spent a total of 28 days attached to the ISS.

The six person international crew from Russia, the US and Japan on Expeditions 39 and 40 unloaded some 2.5 tons of supplies aboard and then repacked it for the voyage home.

The SpaceX resupply capsule is carrying back about 3500 pounds of spacewalk equipment, vehicle hardware, science samples from human research, biology and biotechnology studies, physical science investigations and education activities, as well as no longer needed trash.

“The space station is our springboard to deep space and the science samples returned to Earth are critical to improving our knowledge of how space affects humans who live and work there for long durations,” said William Gerstenmaier, associate administrator for human exploration and operations.

“Now that Dragon has returned, scientists can complete their analyses, so we can see how results may impact future human space exploration or provide direct benefits to people on Earth.”

Among the research investigations conducted that returned samples in the cargo hold were an examination of the decreased effectives of antibiotics in space, better growth of plants in space, T-Cell activation in aging and causes of human immune system depression in the microgravity environment.

The 10 minute long deorbit burn took place as scheduled at 2:10 p.m. EDT (1810 GMT) today.

Dragon returned to Earth for a triple parachute assisted splash down today at around 3:02 p.m. EDT (19:02 GMT) in the Pacific Ocean – some 300 miles west of Baja California.

It will be retrieved by recovery boats commissioned by SpaceX. The science cargo will be extracted and then delivered to NASA’s Johnson Space Center within 48 hours.

Dragon thundered to orbit atop SpaceX’s powerful new Falcon 9 v1.1 rocket on April 18, from Cape Canaveral, Fla.

This unmanned Dragon delivered about 4600 pounds of cargo to the ISS including over 150 science experiments, a pair of hi tech legs for Robonaut 2, a high definition Earth observing imaging camera suite (HDEV), the laser optical communications experiment (OPALS), the VEGGIE lettuce growing experiment as well as essential gear, spare parts, crew provisions, food, clothing and supplies to the six person crews living and working aboard in low Earth orbit.

It reached the ISS on April 20 for berthing.

Dragon is the only unmanned resupply vessel supply that also returns cargo back to Earth.

The SpaceX-3 mission marks the company’s third resupply mission to the ISS under the $1.6 Billion Commercial Resupply Services (CRS) 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.

The SpaceX Dragon is among a trio of American vehicles, including the Boeing CST-100 and Sierra Nevada Dream Chaser vying to restore America’s capability to fly humans to Earth orbit and the space station by late 2017, using seed money from NASA’s Commercial Crew Program (CCP) in a public/private partnership. The next round of contracts will be awarded by NASA about late summer 2014.

Another significant milestone was the apparently successful attempt by SpaceX to accomplish a controlled soft landing of the Falcon 9 boosters first stage in the Atlantic Ocean for eventual recovery and reuse. It was a first step in a guided 1st stage soft landing back at the Cape.

The next unmanned US cargo mission to the ISS is set for early morning on June 10 with the launch of the Orbital Sciences Cygnus freighter atop an Antares booster from a launch pad at NASA’s Wallops Flight Facility on the eastern shore of Virginia.

To close out their final week aboard the International Space Station, three of the six Expedition 39 crew members are completing their unloading tasks inside the docked commercial SpaceX Dragon cargo freighter and other duties while teams at Mission Control in Houston conduct delicate robotics work outside with dazzling maneuvers of the Dextre robot to remove the last external experiment from the vessels storage truck.

See a dazzling gallery of photos of Dextre dangling outside the docked Dragon depot – above and below.

On Monday, May 5, the robotics team at NASA Mission Control Center at the Johnson Space Center in Houston carefully guided Canada’s Dextre robotic “handyman” attached to the end of the 57-foot long Canadarm2 to basically dig out the final payload item housed in the unpressurized trunk section at the rear of the SpaceX Dragon cargo vessel docked to the ISS.

Dextre stands for “Special Purpose Dexterous Manipulator” and was contributed to the station by the Canadian Space Agency. It measures 12 feet tall and is outfitted with a pair of arms and an array of finely detailed tools to carry out intricate and complex tasks that would otherwise require spacewalking astronauts.

The massive orbiting outpost was soaring some 225 miles above the home planet as Dextre’s work was in progress to remove the Optical PAyload for Lasercomm Science, or OPALS, from the Dragon’s truck.

The next step is to install OPALS on the Express Logistics Carrier-1 (ELC-1) depot at the end of the station’s port truss on Wednesday.

Monday’s attempt was the second try at grappling OPALS. The initial attempt last Thursday “was unsuccessful due to a problem gripping the payload’s grapple fixture with the Special Purpose Dextrous Manipulator, or Dextre,” NASA reported.

A software patch solved the problem.

Dragon thundered to orbit atop SpaceX’s powerful new Falcon 9 v1.1 rocket on April 18, from Cape Canaveral, Fla.

This unmanned Dragon delivered about 4600 pounds of cargo to the ISS including over 150 science experiments, a pair of hi tech legs for Robonaut 2, a high definition Earth observing imaging camera suite (HDEV), the laser optical communications experiment (OPALS), the VEGGIE lettuce growing experiment as well as essential gear, spare parts, crew provisions, food, clothing and supplies to the six person crews living and working aboard in low Earth orbit, under NASA’s Commercial Resupply Services (CRS) contract.

OPALS uses laser light instead of radio waves to beam back precisely guided data packages to ground stations. The use of lasers should greatly increase the amount of information transmitted over the same period of time, says NASA.

The science experiments carried aboard Dragon are intended for research to be conducted by the crews of ISS Expeditions 39 and 40.

Robotics teams had already pulled out the other payload item from the truck, namely the HDEV imaging suite. It is already transmitting back breathtaking real time video views of Earth from a quartet of video cameras pointing in different directions mounted on the stations exterior.

The SpaceX CRS-3 mission marks the company’s third 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.

After spending six months in space, Station Commander Koichi Wakata from Japan as well as NASA astronaut Rick Mastracchio and Russian cosmonaut Mikhail Tyurin will be departing the station in a week aboard their Soyuz TMA-11M spacecraft on May 13 at 6:33 p.m. EDT.

They are scheduled to land some 3.5 hours later in the steppes of Kazakhstan at 9:57 p.m. (7:57 a.m. Kazakh time on May 14). The events will be carried live on NASA TV.

To prepare for the journey home, the trio also completed fit checks on their Russian Sokol launch and entry suits on Monday.

Meanwhile Dragon is also set to depart the station soon on May 18 for a parachute assisted splashdown and recovery by boats in the Pacific Ocean west of Baja California.

Dragon has been docked to the station since arriving on Easter Sunday morning, April 20.

It was grappled using Canadarm 2 and berthed at the Earth facing port of the Harmony module by Commander Wakata and flight engineer Mastracchio while working at the robotics work station inside the seven windowed domed Cupola module.

For the return trip, the Expedition 39 crew is also loading Dragon with precious science samples collected over many months from the crews research activities as well as trash and no longer needed items.

The powerful SpaceX Falcon 9 rocket that launched successfully on a cargo delivery run for NASA bound for the Space Station on Friday, April 18, from Cape Canaveral, Fla, also had a key secondary objective for the company aimed at experimenting with eventually recovering the rockets first stage via the use of landing legs and leading to the boosters refurbishment and reuse further down the road.

Marking a first of its kind test, this 20 story tall commercial Falcon 9 rocket was equipped with a quartet of landing legs to test controlled soft landing techniques first in the ocean and then back on solid ground at some later date this year or next – by reigniting the 1st stage engines for a guided touchdown.

The 12 foot diameter Falcon 9 rocket would sprout the legs just prior to water impact for the controlled soft landing in the Atlantic Ocean, guided by SpaceX engineers.

Prior to the launch SpaceX managers were careful not to raise expectations.

“The entire recovery of the first stage is completely experimental,” said Hans Koenigsmann, SpaceX vice president of mission assurance. “It has nothing to do with the primary mission.”

He estimated the odds of successfully retrieving an intact booster at merely 30 or 40 percent.

Following Friday’s blastoff, SpaceX reported they made significant strides towards that goal of a 1st stage recovery.

SpaceX engineers had preprogrammed the spent first stage to relight several Merlin 1 D engines after completing the boost phase and stage seperation to stabilize it, reduce its roll rate and then gradually lower its altitude back down to the Atlantic Ocean’s surface for a soft landing attempt and later possible recovery by retrieval ships.

All these critical steps seemed to go fairly well in initial reports that are subject to change.

SpaceX CEO and founder Elon Musk reported at a post launch briefing and later tweeted further updates that the Falcon 9 first stage actually made a good water landing despite rough seas, with waves swelling at least six feet.

“Roll rate close to zero (v important!).”

“Data upload from tracking plane shows landing in Atlantic was good! Several boats enroute through heavy seas,” Musk tweeted.

Furthermore he reported that the 1st stage survived the ocean touchdown.

“Flight computers continued transmitting for 8 seconds after reaching the water. Stopped when booster went horizontal.”

Because of the high waves, the recovery boats had difficulty reaching the booster in the recovery area located some two hundred miles off shore from Cape Canaveral.

Several previous attempts by SpaceX to recover the first stage via parachutes and thrusters were not successful. So SpaceX adopted this new approach with the landing legs and 1st stage Merlin 1 D engines.

Further details will be proved when they become available.

The attachment of the 25 foot long 1st stage landing legs to SpaceX’s next-generation Falcon 9 rocket for ocean recovery counts as a major step towards the firm’s future goal of building a fully reusable rocket and dramatically lowering launch costs compared to expendable boosters.

The eventual goal is to accomplish a successful first stage touchdown by the landing legs on solid ground back somewhere near on Cape Canaveral, Florida.

Musk said that SpaceX is still working out the details on finding a suitable landing location with NASA and the US Air Force.

Extensive work and testing remains to develop and refine the technology before a land landing will be attempted by the company, says Musk.

It will be left to future missions to accomplish a successful first stage touchdown by the landing legs back on solid ground back through a series of ramped up rocket tests at Cape Canaveral, Florida.

“Even though we probably won’t get the stage back, I think we’re really starting to connect the dots of what’s needed,” Musk said at the briefing.

“There are only a few more dots that need to be there to have it all work. I think we’ve got a decent chance of bringing a stage back this year, which would be wonderful.”

Overall Musk was very pleased with the performance of the rocket and the landing leg test.

“I would consider it a success in the sense that we were able to control the boost stage to a zero roll rate, which is previously what has destroyed the stage, an uncontrolled roll, where the on-board nitrogen thrusters weren’t able to control the aerodynamic torque and spun up.”

“This time, with more powerful thrusters and more nitrogen propellant, we were able to null the roll rates.”

“I’m feeling pretty excited,” Musk stated. “This is a happy day. Most important of all is that we did a good job for NASA.”

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

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

Indeed Dragon is loaded with nearly 5000 pounds of cargo, about double the weight carried previously.

If all goes well, Dragon will reach the ISS early on Easter Sunday morning after a two day orbital chase.

Station crew members Rick Mastracchio and Steven Swanson will grapple the Dragon cargo freighter with the 57 foot long Canadarm2 on Easter Sunday at about 7:14 a.m. and then berth it at the Earth-facing port of the Harmony module.

NASA TV coverage of the Easter Sunday grappling process will begin at 5:45 a.m. with berthing coverage beginning at 9:30 a.m. : http://www.nasa.gov/ntv

UPDATE: Thanks to several people on Twitter who pointed out that what is seen in the footage here is the the upper stage of the Falcon 9, the Dragon capsule, and the ejected solar panel covers moving along together in orbit around the Earth. And as Phil Plait pointed out, since this was taken a few minutes after the capsule separated from the rocket upper stage, all the individual things you see here were still near each other in space.

We need to say it: astrophotographer Thierry Legault has done it again! Here’s an absolutely fantastic capture of the SpaceX Dragon capsule just 25 minutes after it launched from Cape Canaveral Air Force Station, as it passed over Europe. Here, Legault captured footage of Dragon crossing the Big Dipper as seen from Paris at 19:50 UTC, April 18, 2014.

“It was an incredible vision: 4 bright dots moving together!” Legault told Universe Today via email.

Check out more of his amazing astrophotography and even some of his tips and tricks at Thierry’s website.

SpaceX Dragon launch to ISS Marches Towards April 18 Liftoff after Helium Leak Forces Scrub – Watch Live

NASA and SpaceX are marching forward towards a Friday, April 18 liftoff attempt for the Falcon 9 rocket sending a commercial Dragon cargo craft on the company’s third resupply mission to the International Space Station following the scrubbed launch attempt on Monday, April 14 – forced by the discovery of a Helium gas leak inside the rocket during the latter stages of the countdown.

An on time blastoff of the upgraded Falcon 9 sets the stage for an Easter Sunday rendezvous and berthing of the Dragon resupply spacecraft at the massive orbiting outpost packed with almost 5000 pounds of science experiments and supplies for the six person crew.

However the weather prognosis is rather iffy for Friday afternoons launch attempt at 3:25:21 p.m. EDT from Space Launch Complex 40 at Cape Canaveral Air Force Station in Florida.

Forecasters predict only a 40 percent “GO” of acceptable weather conditions at the appointed liftoff time of the SpaceX-3 mission – roughly the time when the Earth’s rotation moves the rocket into the plane of the space stations orbit.

Meteorologists with the U.S. Air Force 45th Weather Squadron are predicting a significant chance of rain showers and thunderstorms in the Florida Space coast launch area that could violate three launch rules, namely the Thick Cloud, Lightning and Flight Through Precipitation rules.

In the event of a scrub for any reason on Friday, NASA, SpaceX and Air Force managers approved another backup launch opportunity on Saturday, April 19 at 3:02:42 p.m.

The weather outlook for a Saturday liftoff improves somewhat to 60 percent “GO”.

Originally, Monday and Friday were the only available launch target dates this week.

Assuming a successful Falcon 9 launch on Friday, station crew members Rick Mastracchio and Steven Swanson will grapple the Dragon cargo freighter with the 57 foot long Canadarm2 on Easter Sunday morning, April 20, at 7:14 a.m. at then berth it at the Earth-facing port of the Harmony module.

Monday’s launch attempt was scrubbed about an hour before liftoff when SpaceX mission controllers and engineers detected that a helium valve in the pneumatic system for stage separation between the first and second stages was not holding the specified pressure.

The success of the mission was therefore dependent on the perfect operation of a backup check valve for the stage separation pistons.

Although no technical issues were detected with the backup valve, the anamolous situation violated SpaceX launch rules.

“SpaceX policy is not to launch with any known anomalies,” said SpaceX in a statement.

The erect Falcon 9 was lowered back to the horizontal position so that SpaceX engineers could swap out the faulty helium valve, as well as conduct a complete inspection of the rocket to look for signs of any other issues that may have contributed to the valve not working as designed, said SpaceX.

This unmanned SpaceX mission dubbed CRS-3 will deliver some 5000 pounds of science experiments, a pair of hi tech legs for Robonaut 2, a high definition imaging camera suite, an optical communications experiment (OPALS) and essential gear, the VEGGIE lettuce growing experiment, spare parts, crew provisions, food, clothing and supplies to the six person crews living and working aboard the ISS soaring in low Earth orbit under NASA’s Commercial Resupply Services (CRS) contract.

To date SpaceX has completed two operational cargo resupply missions and a test flight. The last flight dubbed CRS-2 blasted off a year ago on March 1, 2013 atop the initial version of the Falcon 9 rocket.

NASA awarded contracts to SpaceX and competitor Orbital Sciences to develop unmanned cargo freighters via CRS to restore US capability to resupply the ISS following the shutdown of the space shuttle program in 2011.

SpaceX is under contract to NASA to deliver 20,000 kg (44,000 pounds) of cargo to the ISS during a dozen Dragon cargo spacecraft flights through 2016 at a cost of about $1.6 Billion.

The next launch of Orbital Sciences Antares/Cygnus commercial rocket to the ISS from NASA Wallops, VA, is tentatively slated for May 6. But the target date hinges on when this SpaceX-3 mission actually flies and could slip into mid-June.

US Spy Sat and SpaceX Set for Double Barreled Blastoffs After Critical Cape Canaveral Radar Revitalized

The Florida Space Coast is about to ignite with a doubled barreled dose of spectacular rocket launches from Cape Canaveral over the next few days that were suddenly postponed two weeks ago amidst final launch preparations when an electrical short completely knocked out use of the US Air Force’s crucial tracking radar that is mandatory to insure public safety.

A pair of liftoffs vital to US National Security and NASA/SpaceX are now slated for April 10 and April 14 from Cape Canaveral Air Force Station after revitalizing the radar systems.

The tracking radar is an absolutely essential asset for the Eastern Range that oversees all launches from Cape Canaveral Air Force Station and the Kennedy Space Center in Florida.

The United Launch Alliance Atlas V is now slated to launch on Thursday, April 10 at 1:45 p.m. EDT.

The Atlas V rocket is carrying the super secret NROL-67 intelligence gathering spy satellite for the National Reconnaissance Office (NRO).

The SpaceX Falcon 9 is slated to launch on Monday, April 14 at 4:58 p.m. EDT.

The Falcon 9 is lofting a SpaceX Dragon cargo ship and delivering some 5000 pounds of science experiments and supplies for the six man space station crew – under a resupply contract with NASA.

The pair of liftoffs of the Atlas V and Falcon 9 boosters for the NRO and SpaceX/NASA had been slated just days apart on March 25 and March 30, respectively.

I was on site at Cape Canaveral Launch Pad 41 photographing the Atlas V rocket carrying the NRO payload in anticipation of the launch.

Shortly thereafter a fire of unexplained origin in the radar equipment unexpected occurred and knocked the tracking radar off line. When no quick fix was possible, both launches were delayed indefinitely pending repairs.

“The tracking radar experienced an electrical short, overheating the unit and rendering the radar inoperable,” said the USAF in a statement I received from the 45th Space Wing that controls the critical launch control systems, communications, computers and radar elements at the Eastern Range.

On Monday, April 7, the Air Force announced that range repairs were on target and that a retired, inactive radar had been brought back online.

“A radar that was previously in standby status has been brought back to operational status while the repair work is being accomplished,” said the USAF in a statement.

A fully functional tracking radar is an absolute requirement to ensure the success and safety of every rocket launch.

Insufficient maintenance and antiquated equipment due to a lack of US government funding and investment in infrastructure may be at fault for the electrical short.

The Eastern range radar must function perfectly in order to destroy any rocket in a split second in the event it abruptly veers off course towards the nearby populated areas along the Florida Space Coast.

The Atlas V rocket was rolled out earlier today to Space Launch Complex 41 in preparation for Thursday’s NROL-67 launch. The weather forecast shows a 90 percent chance of favorable weather conditions for launch.
