KENNEDY SPACE CENTER, FL – Following a perfectly executed three day orbital rendezvous, NASA astronaut and Expedition 47 Commander Tim Kopra successfully reached out with the International Space Station’s robotic arm, Canadarm2, grabbed hold and captured Orbital ATK’s commercial Cygnus cargo freighter at 6:51 a.m. EDT, this morning, Saturday, March 26, 2016.

The ISS and Cygnus were soaring some 250 miles (400 kilometers) over the Indian Ocean at the time of capture following the cargo crafts blastoff atop a two stage United Launch Alliance (ULA) Atlas V at 11:05 p.m. EDT on Tuesday, March 22, 2016 from Space Launch Complex 41 on Cape Canaveral Air Force Station, Fl.

Robotics officers on the ground in Houston working with the station crew high above then maneuvered Cygnus – holding over 3.5 tons of critical cargo supplies and science – into position for final installation and berthing to the orbiting laboratory’s Earth-facing port on the Unity module a few hours later. It was finally bolted fully into place at approximately 10:52 a.m. EDT.

This Cygnus is named the S.S. Rick Husband in honor of Col. Rick Husband, the late commander of Space Shuttle Columbia, which was tragically lost with its crew of seven NASA astronauts during re-entry on its final flight on Feb. 1, 2003.

The crew plans to open the hatch to the SS Rick Husband tomorrow morning on Easter Sunday, March 26.

The Orbital ATK Cygnus CRS-6 space freighter is loaded with 3513 kg (7700 pounds) of science experiments and hardware, crew supplies, spare parts, gear and station hardware for the orbital laboratory in support of over 250 research experiments being conducted on board by the Expedition 47 and 48 crews.

All of Cygnus maneuvers were “executed to perfection for a flawless approach and rendezvous” after the three day trip from Florida to the ISS, as the vehicle closed in to within a few meters for grappling, said NASA commentator Rob Navius.

NASA TV showed spectacular HD views of Cygnus and its UltraFlex solar arrays – deployed 2 hours after launch – from station and robotic arm cameras during the final approach operation, as flight controllers closely monitored all spacecraft systems.

“The crew is ready for Cygnus approach to the capture point,” radioed Kopra.

“Station you are go for capture,” Mission Control radioed back.

Cygnus was placed into free drift mode before capture to prevent any accidental perturbations in the final seconds.

From his robotics work station in the Cupola, Kopra then put the arm in motion by about 6:40 a.m. EDT, during the final phase of the final approach. He extended the 57 foot long (19 meter long) arm to reach out and grab the aft end of Cygnus cargo craft at its grappling pin by closing the snares on the end effector.

ESA astronaut Tim Peake served as backup for arm operations while NASA astronaut Jeff Williams monitored Cygnus systems.

The SS Rick Husband was rock steady during its capture as the station was flying over South Africa and the Indian Ocean.

“Capture confirmed,” reported Navius just moments before the video downlink was temporarily lost as the station communications moved between satellites.

“Excellent work gentleman. Much appreciated. Made that look easy,” radioed Jeremy Hansen, a Canadian Space Agency astronaut from Houston mission control.

“We’d also like to say we are really honored to bring aboard the SS Rick Husband to the International Space Station,” radioed Kopra. “He was a personal hero to many of us. This will be the first Cygnus honoree who was directly involved with the construction of this great station.”

It took about 9 minutes to complete the approach from the 30 meter distant hold point to the final capture point where the SS Rick Husband Cygnus arrived at about 6:37 am EDT. NASA TV showed the grapple fixture gradually coming into view.

Cygnus approached precisely within the center of the approach corridor, said Peake, during continuing updates as the ship moved closer to the targeted berthing port. It was perfectly aligned for its capture point.

Cygnus grapple fixture is located at the bottom end of the vehicles service module, beside the thruster.

Kopra and Peake are spending their 103rd day on the station today. While Williams arrived just 8 days ago.

All burns to get to the initial rendezvous point in the keep out sphere 250 meters away were “right on the money. Every burn has been on course and on target, said NASA JSC commentator Navius in Houston, as Cygnus soared some 400 km over the Pacific.

“Everything has gone off without a hitch. A rock solid approach.”

Flight controllers in Houston and Orbital ATK’s Dulles control headquarters then gave the go ahead to resume moving and approach closer to the 30 meter hold point.

The actual berthing operation took place about an hour later than expected to double check that everything was precisely aligned and communications were fully established.

Controllers used the arm to move Cygnus in for capture. They commanded four gangs of four bolts to latch Cygnus to the common berthing mechanism (CBM) on the internally positioned Unity modules nadir or Earth-facing port.

The first and second stage captures were successfully completed by 10:52 a.m. EDT this morning, marking the official hard mating of Cygnus and the station.

When the ISS Expedition 47 crew members open the hatch, they will be greeted with a sign noting the spacecraft was named SS Rick Husband in honor of the STS-107 mission commander.

The SS Rick Husband Cygnus is actually at the vanguard of a “constellation” of three resupply ships arriving at the station over a three week period of three weekends.

Next comes the Russian Progress 63 which will dock at Russia’s Zvezda module next weekend after launching this Thursday from site 31 at Kaszakhstan carrying another three tons of supplies.

Following Progress is the SpaceX Return To Flight (RTF) mission dubbed SpaceX CRS-8.

It is slated to launch on April 8 and arrive at the ISS on April 10 for berthing to the Earth-facing port of the Harmony module – at the end of the station where NASA space shuttles formerly docked. It carries another 3.5 tons of supplies.

So altogether the trio of international cargo ships will supply over 12 tons of station supplies in rapid succession over the next 3 weeks.

This choreography will set up America’s Cygnus and Dragon resupply craft to simultaneously be present and reside attached at adjacent ports on the ISS for the first time in history.

Plans currently call for Cygnus to stay at station for approximately two months until May 20th, when it will be unbolted and unberthed for eventual deorbiting and reentry.

But first it will stay on orbit for about another eight days, said Orbital ATK’s Cygnus program manager Frank DeMauro in an interview with Universe Today.

After unberthing, Cygnus will be used to conduct several experiments including the Saffire-1 experiment, it will deploy nanosats from an externally mounted carrier, and the REBR experiment will monitor the burn-up of Cygnus during the fiery reentry into the Earth’s atmosphere, said DeMauro.

Orbital ATK’s attention then shifts to the next Cygnus launch on the Return to Flight, or RTF, mission of the firms Antares rocket from NASA Wallops on the eastern shore of Virginia.

OA-6 is only the second Cygnus to be launched atop a ULA Atlas V rocket, following the OA-4 mission last December.

The CRS-6/OA-6 flight is also the second flight of the enhanced Cygnus variant, that is over 1 meter longer and sports 50% more volume capability.

Thus it is capable of carrying a much heavier payload of some 3500 kg (7700 lbs) vs. a maximum of 2300 kg (5070 lbs) for the standard version.

KENNEDY SPACE CENTER, FL – A stunningly beautiful nighttime launch mesmerized delighted spectators as it roared off a Florida space coast launch pad late Tuesday night, March 22, on a mission for NASA stocked with over three tons of science and supplies bound for the multinational crews working aboard the International Space Station (ISS).

A United Launch Alliance (ULA) Atlas V rocketed raced to orbit from Cape Canaveral Air Force Station, Fl, carrying an enlarged Cygnus commercial resupply spacecraft on the Orbital ATK CRS-6 mission to the ISS.

The venerable Atlas V lifted off right on target at 11:05 p.m. EDT from Space Launch Complex 41 into a picturesque moonlit sky that magnificently illuminated the scattered thin clouds hovering over the seaside launch pad for the hordes of excited folks and families lining the beaches and lucky to witness what may be history’s last launch of a Cygnus from Florida.

Future liftoffs of the private Orbital ATK Cygnus supply truck designed to stock the station will return to their original launch site on Virginia’s eastern shore starting with the next mission for their NASA customer sometime this summer.

Cygnus launches to the ISS normally start from NASA’s Wallops Flight Facility in Virginia.

But a catastrophic failure of the Orbital ATK Antares rocket moments after liftoff on Oct. 28, 2014, forced Orbital to seek and book an alternative launch vehicle while the company redesigned and reengined Antares first stage with new powerful powerplants for the ride to orbit.

The Cygnus has been named the S.S. Rick Husband in honor of Col. Rick Husband, the late commander of Space Shuttle Columbia, which was tragically lost with its crew of seven NASA astronauts during re-entry on its final flight on Feb. 1, 2003.

This flight is also known as OA-6 and is being launched under terms of the firm’s Commercial Resupply Services (CRS) contract with NASA. It also counts as Orbital ATK’s fifth cargo delivery mission to the space station.

OA-6 is loaded with 3513 kg (7700 pounds) of science experiments and hardware, crew supplies, spare parts, gear and station hardware to the orbital laboratory in support over 250 research experiments being conducted on board by the Expedition 47 and 48 crews.

About a quarter of the cargo is devoted to science and research gear. The cargo includes 3279 kg of science investigations, 1139 kg of crew supplies, 1108 kg of vehicle hardware, 157 kg of spacewalk equipment, and 98 kg of computer resources.
Here a NASA description of a few of the scientific highlights:

– Gecko Gripper, testing a mechanism similar to the tiny hairs on geckos’ feet that lets them stick to surfaces using an adhesive that doesn’t wear off,

– Strata-1, designed to evaluate how soil on small, airless bodies such as asteroids behaves in microgravity.

– Meteor, an instrument to evaluate from space the chemical composition of meteors entering Earth’s atmosphere. The instrument is being re-flown following its loss on earlier supply missions.

– Saffire, which will set a large fire inside the Cygnus in an unprecedented study to see how large fires behave in space. The research is vital to selecting systems and designing procedures future crews of long-duration missions can use for fighting fires.

– Cygnus is carrying more than two dozen nanosatellites that will be ejected from either the spacecraft or the station at various times during the mission to evaluate a range of technology and science including Earth observations.

KENNEDY SPACE CENTER, FL – The next Cygnus cargo resupply ship targeted to blastoff for the International Space Station (ISS) on March 22, has been named the S.S. Rick Husband in honor of Col. Rick Husband, the late commander of Space Shuttle Columbia, which was tragically lost with its crew of seven NASA astronauts during re-entry on its final flight on Feb. 1, 2003.

The ‘S.S. Rick Husband’ was announced as the Cygnus delivery vessels name by former astronaut Dan Tani, now senior director of Missions and Cargo Operations for Orbital ATK in Dulles, Virginia, during a media briefing in the clean room processing facility at the Kennedy Space Center in Florida.

“Rick was a very accomplished astronaut, and a devoted husband and father,” said Tani.

The commercial Cygnus cargo freighter was built by Orbital ATK, based in Dulles, Virginia.

Christened the S.S. Rick Husband, the spacecraft is a tribute to NASA astronaut Col. Rick Husband, of U.S. Air Force, who served as commander of Columbia’s STS-107 mission. The mission and all aboard were lost as Columbia disintegrated due to the effects of reentry heating into the Earth’s atmosphere high over Texas.

Final processing of the cargo ship was completed as bunny suited media including myself observed technicians putting the finishing touches on the vehicle inside Kennedy’s Payload Hazardous Servicing Facility (PHSF). Technicians had already finished fueling the vehicle with hydrazine and nitrogen tetroxide.

Liftoff of the commercial resupply services mission to the orbiting outpost is now targeted for Tuesday, March 22, during a 30-minute launch window that opens at 11:05 p.m. EDT.

The Orbital ATK Cygnus spacecraft, also known as Commercial Resupply Services-6 (CRS-6), will launch atop a United Launch Alliance (ULA) Atlas V rocket from the seaside Space Launch Complex 41 at Cape Canaveral Air Force Station (CCAFS) in Florida.

OA-6 is loaded with 3513 kg (7700 pounds) of science experiments and hardware, crew supplies, spare parts, gear and station hardware to the orbital laboratory in support over 250 research experiments being conducted on board by the Expedition 47 and 48 crews.

Overall, Orbital will deliver approximately 28,700 kilograms of cargo to the ISS under the life of the CRS contract, which extends to 2018.

STS-107 was Husband’s second flight to space.

OA-6 is the first Cygnus to named after an astronaut who actually participated in building the ISS – during his first flight as shuttle pilot on the STS-96 mission in 1999.

The prior Cygnus cargo spacecraft was named the S.S. Deke Slayton during the OA-4 mission. OA-4 successfully launched to the ISS in December 2015 – read my on site articles here.

Orbital ATK has named each Cygnus after a deceased NASA astronaut, several of whom later worked for the company.

OA-6 is only the second Cygnus to be launch atop a ULA Atlas V rocket, following the OA-4 mission last December.

The CRS-6/OA-6 flight is also the second flight of the enhanced Cygnus variant, that is over 1 meter longer and sports 50% more volume capability.

Thus it is capable of carrying a much heavier payload of some 3500 kg (7700 lbs) vs. a maximum of 2300 kg (5070 lbs) for the standard version.
