Russian Progress Cargo Ship Launch Failure Deals Setback to ISS

KENNEDY SPACE CENTER, FL – An unmanned Russian Progress resupply ship bound for the International Space Station (ISS) was lost shortly after launch from the Baikonur Cosmodrome in Kazakhstan on Thursday when its Soyuz booster suffered a catastrophic anomaly in the third stage, and the craft and its contents were totally destroyed.

The Russian launch failure deals somewhat of a setback to the ever ongoing efforts by all the space station partners to keep the orbiting outpost well stocked with critical supplies of food and provisions for the multinational six person crew and science experiments to carry out the research activities for which the station was assembled.

The three stage Soyuz-U rocket failed in flight around six and a half minutes after what had been an otherwise flawless nighttime liftoff from the Baikonur Cosmodrome at 9:51 a.m. EST (8:51 p.m. Baikonur time), Thursday, Dec. 1.

Telemetry from the Progress 65 vehicle, also known as Progress MS-04, stopped after 382 seconds of flight while soaring about 190 km over the southern Russian Republic of Tyva.

“The Russian space agency Roscosmos has confirmed a Progress cargo resupply spacecraft bound for the International Space Station and her six person crew has lost shortly after launch,” said NASA.

“According to preliminary information, the contingency took place at an altitude of about 190 km over remote and unpopulated mountainous area of the Republic of Tyva,” said Roscosmos in a statement.

The Progress vehicle burned up during the resulting and unplanned fiery plummet through the Earth’s atmosphere.

This was the second failure of a Russian Progress launch in the past two years. The last failure took place in April 2015 when the third stage separation failed – sending the vehicle spinning wildly out of control and destroying the Progress 59 freighter.

Per protocol, the Russian space agency Roscosmos has formed a state commission to investigate the accident, seek out the root cause and implement measures to prevent such failures in the future.

“The first few minutes of flight were normal, but Russian flight controllers reported telemetry data indicating a problem during third stage operation. The Russians have formed a State Commission and are the source for details on the specific failure cause,” NASA said.

Crew launches on a different version of the Soyuz rocket were delayed and put on hold several months following last year’s Progress 59 failure and accident investigation.

Despite the failure there was no immediate impact on the current Expedition 50 crew and life goes on.

“The loss of the cargo ship will not affect the normal operations of the ISS and the life of the station crew,” said Roscosmos.

“The spacecraft was not carrying any supplies critical for the United States Operating Segment (USOS) of the station,” NASA reported.

Currently there is a satisfactory level of supplies.

“Six crew members living aboard the space station are safe and have been informed of the mission’s status. Both the Russian and U.S. segments of the station continue to operate normally with onboard supplies at good levels.”

However the continued useful utilization of the million pound station is totally dependent on receiving a steady train of supplies from Earth – comprising Russian, US and Japanese cargo freighters launching multiple times per year.

The Progress 65 cargo freighter was jam packed with 2.6 tons of food, fuel, and supplies for the space station crew, including approximately 1,400 pounds of propellant, 112 pounds of oxygen, 925 pounds of water, and 2,750 pounds of spare parts, supplies and scientific experiment hardware.

The Progress was carrying a few items from NASA but they are all replaceable, says NASA. The US items packed on board included spare parts for the station’s environmental control and life support system, research hardware, crew supplies and crew clothing.

Had all gone well, Progress 65 would have docked to the rear port of the space station’s Russian Zvezda Service Module at 11:43 a.m. Saturday, Dec. 3.

Japan is all set to launch the next cargo flight to the ISS on Friday, Dec. 9 when the Japan Aerospace Exploration Agency (JAXA) HTV-6 resupply ship will blast off atop the H-II rocket.

The most recent US commercial cargo launch to the ISS took place on Oct. 17 with blastoff of the Orbital ATK Antares rocket from NASA Wallops in Virginia, which delivered the Cygnus OA-5 resupply freighter to orbit. It docked to the ISS on Oct 23.

The next US cargo launch could be either an Orbital ATK Cygnus launch atop a ULA Atlas V in March 2017 or a SpaceX Dragon launch perhaps in Jan 2017.

The US has also suffered ISS cargo launch failures from both of the commercial resupply providers; SpaceX on the Dragon CRS-7 mission in Jun 2015 and Orbital ATK on the Cygnus Orb-3 mission in October 2014.

The cargo ships function as a railroad to space and function as the lifeline to keep the station continuously crewed and functioning. Without periodic resupply by visiting vehicles from the partner nations the ISS cannot continue to operate.

After a two year gap, the first Cygnus cargo freight train from Virginia bound for the International Space Station (ISS) arrived earlier this morning – restoring this critical supply route to full operation today, Sunday, Oct. 23.

The Orbital ATK Cygnus cargo spacecraft packed with over 2.5 tons of supplies was berthed to an Earth-facing port on the Unity module of the ISS at 10:53 a.m. EDT.

The Cygnus OA-5 mission took flight atop the first re-engined Orbital ATK Antares rocket during a spectacular Monday night liftoff on Oct. 17 at 7:40 p.m. EDT from the Mid-Atlantic Regional Spaceport pad 0A at NASA’s Wallops Flight Facility on Virginia’s picturesque Eastern shore.

Antares pair of RD-181 first stage engines were firing with some 1.2 million pounds of liftoff thrust and brilliantly lighting up the crystal clear evening skies in every direction to the delight of hordes of spectators gathered from near and far.

Cygnus is loaded with over 5,100 pounds of science investigations, food, supplies and hardware for the space station and its six-person multinational crew.

This was the first Antares launch from Virginia in two years following the rockets catastrophic failure just moments after liftoff on Oct. 28, 2014, which doomed the Orb-3 resupply mission to the space station – as witnessed by this author.

Orbital ATK’s Antares commercial rocket had to be overhauled with the completely new RD-181 first stage engines- fueled by LOX/kerosene – following the destruction of the Antares rocket and Cygnus supply ship two years ago.

The 14 story tall commercial Antares rocket launched for the first time in the upgraded 230 configuration – powered by a pair of the new Russian-built RD-181 first stage engines.

The RD-181 replaces the previously used AJ26 engines which failed shortly after the last liftoff on Oct. 28, 2014 and destroyed the rocket and Cygnus cargo freighter.

The launch mishap was traced to a failure in the AJ26 first stage engine turbopump and forced Antares launches to immediately grind to a halt.

After a carefully choreographed five day orbital chase, Cygnus approached the million pound orbiting outpost this morning.

After it was within reach, Expedition 49 Flight Engineers Takuya Onishi of the Japan Aerospace Exploration Agency and Kate Rubins of NASA carefully maneuvered the station’s 57.7-foot (17.6-meter) Canadian-built robotic arm to reach out and capture the Cygnus OA-5 spacecraft at 7:28 a.m. EDT.

It was approximately 30 feet (10 meters) away from the station as Onishi and Rubins grappled the resupply ship with the robotic arms snares.

After leak checks, the next step is for the crew to open the hatches between the pressurized Cygnus and Unity and begin unloading the stash aboard.

The 21-foot-long (6.4-meter) spacecraft is scheduled to spend about five weeks attached to the station. The crew will pack the ship with trash and no longer needed supplies and gear.

It will be undocked in November and then conduct several science experiments, including the Saffire fire experiment and deploy cubesats.

Thereafter it will be commanded to conduct the customary destructive re-entry in Earth’s atmosphere.

The Cygnus spacecraft for the OA-5 mission is named the S.S. Alan G. Poindexter in honor of former astronaut and Naval Aviator Captain Alan Poindexter.

Under the Commercial Resupply Services (CRS) contract with NASA, Orbital ATK will deliver approximately 28,700 kilograms of cargo to the space station. OA-5 is the sixth of these missions.

Antares ‘Return to Flight’ Blastoff Soars to Stellar Success

NASA WALLOPS FLIGHT FACILITY, VA – The ‘Return to Flight’ blastoff of Orbital ATK’s upgraded Antares rocket soared to a stellar success this evening, Oct. 17, on a space station bound mission to stock the orbiting outpost with two and a half tons of science and supplies.

The re-engined Orbital ATK Antares/Cygnus OA-5 mission lifted off at 7:45 p.m. EDT, tonight from the Mid-Atlantic Regional Spaceport pad 0A at NASA’s Wallops Flight Facility on Virginia’s picturesque Eastern shore spewing about 1.2 million pounds of liftoff thrust and brilliantly lighting up the evening skies in every direction.

Sporting a pair of more powerful new RD-181 engines, Antares roared off the launch pad somewhat more swiftly than the previous launches and consequently reached its preliminary orbit about one minute earlier.

Cygnus separated from the second stage as planned about 9 minutes after liftoff. The launch marked the first nighttime liftoff of Antares.

“It’s great to see launches to the International Space Station happening again from the Virginia coast – and it shows what can be accomplish with a close partnership of federal and state agencies, along with the U.S. industry, all working together,” said NASA Administrator Charles Bolden.

“I am incredibly proud of what you have all done,” said Bolden in post launch remarks to the launch team at Wallops Launch Control Center. “Thank you for all your hard work.”

This was the first Antares launch in two years following the rockets catastrophic failure just moments after liftoff on Oct. 28, 2014, which doomed the Orb-3 resupply mission to the space station – as witnessed by this author.

The weather was absolutely perfect at 100% GO by launch time and consequently was visible to millions of East Coast residents from the Carolinas to Maine as well as inland regions.

Visibility was aided by cloudless evening skies that afforded a spectacular long distance view of the engine firings for both the first and second stages, as the rocket accelerated to orbit in a southeastwardly direction before arcing over towards the African continent.

The power producing and life giving solar arrays were deployed and unfurled about two hours after liftoff, finished at about 9:40 p.m.

Cygnus is loaded with over 5,100 pounds of science investigations, food, supplies and hardware for the space station and its crew.

After Cygnus arrives at the ISS on Sunday, Oct. 23, Expedition 49 Flight Engineers Takuya Onishi of the Japan Aerospace Exploration Agency and Kate Rubins of NASA will grapple the spacecraft with the space station’s 57 foot long Canadian-built robotic arm. It will take hold of the Cygnus,

Ground controllers will then command the station’s arm to rotate and install it on the bottom of the station’s earth facing Unity module.

The Cygnus spacecraft will spend about five weeks attached to the space station. Cygnus will remain at the space station until November, when the spacecraft will depart the station and begin a fire experiment dubbed Saffire-II.

The 14 story tall commercial Antares rocket launched for the first time in the upgraded 230 configuration – powered by a pair of the new Russian-built RD-181 first stage engines.

For the OA-5 mission, the Cygnus advanced maneuvering spacecraft was loaded with approximately 2,425 kg (5,346 lb.) of supplies and science experiments for the International Space Station (ISS). The cargo was packed inside 56 cargo bags of multiple sizes.

The experiments will support dozens of new and existing investigations as the space station crews of Expeditions 49 and 50 contribute to about 250 science and research studies.

Among the science payloads aboard the Cygnus OA-5 mission is the Saffire II payload experiment to study combustion behavior in microgravity. Data from this exp,eriment will be downloaded via telemetry. In addition, a NanoRack deployer will release Spire Cubesats used for weather forecasting. These secondary payload operations will be conducted after Cygnus departs the space station.

Here is the Cygnus payload manifest:

Payloads:
• Spacecraft Fire Experiment-II (Saffire-II)
• Fast Neuron Spectrometer
• ACM and Experiment Tray
• SLMMD
Cargo:
• ISS Experiment Hardware
• EVA Equipment– EMU Repair Kit– EVA Supplies

Antares Return to Flight Set for Magnificent Monday Night Launch – Watch Live

NASA WALLOPS FLIGHT FACILITY, VA – The ‘Return to Flight’ blastoff of Orbital ATK’s upgraded Antares rocket will have to wait one more day to come to fruition with a magnificent Monday night launch – after a technical scrub was called this afternoon, Oct. 16, at NASA’s Virginia launch base due to a faulty cable.

The launch potentially offers a thrilling skyshow to millions of US East Coast spectators if all goes well.

Despite picture perfect Fall weather, technical gremlins intervened to halt Sunday nights planned commercial cargo mission for NASA carrying 2.5 tons of science and supplies bound for the International Space Station (ISS).

The launch of the Orbital ATK CRS-5 mission is now scheduled for October 17 at 7:40 p.m. EDT, from the Mid-Atlantic Regional Spaceport pad 0A at NASA’s Wallops Flight Facility on Virginia’s picturesque Eastern shore.

You can watch the launch live on NASA TV as well as the agency’s website beginning at 6:30 p.m. EDT Oct 17.

Mondays liftoff is slated to take place approximately 23 minutes earlier then Sunday’s hoped for time of 8:03 p.m. EDT in order to match the moment when the orbital plane of the station passes on NASA Wallops.

The weather outlook on Monday remains extremely favorable with a 95 percent chance of acceptable conditions at launch time.

A nearly full moon has risen over Antares the past few days at the launch pad.

Announcement of the launch scrub of the mission – also known as OA-5 – came just as the six hour countdown was set to begin after engineers discovered the bad cable.

“Today’s launch of Orbital ATK’s Antares rocket is postponed 24 hours due to a ground support equipment (GSE) cable that did not perform as expected during the pre-launch check out,” officials at NASA Wallops said.

The faulty cable was a component of the rocket’s hold down system at the pad, Orbital ATK officials told Universe Today after the scrub was announced.

Technicians have spares on hand and are working now to replace the cable in time to permit a Monday evening launch.

“We have spares on hand and rework procedures are in process. The Antares and Cygnus teams are not currently working any technical issues with the rocket or the spacecraft.”

Besides the cable the rocket is apparently in perfect shape.

“The Antares and Cygnus teams are not currently working any technical issues with the rocket or the spacecraft.”

Antares launches have been on hold for two years after it was grounded following its catastrophic failure just moments after liftoff on Oct. 28, 2014 that doomed the Orb-3 resupply mission to the space station – as witnessed by this author.

The 14 story tall commercial Antares rocket also will launch for the first time in the upgraded 230 configuration – powered by new Russian-built first stage engines designed and manufactured by Energomesh.

The 133-foot-tall (40-meter) Antares was rolled out to pad 0A on Thursday, Oct. 13 – three days prior to Sunday’s intended launch date. It was raised to the vertical launch position on Friday.

The two stage Antares will carry the Orbital OA-5 Cygnus cargo freighter to orbit on a flight bound for the ISS and its multinational crew of astronauts and cosmonauts.

The launch marks the first nighttime liftoff of the Antares – and it could be visible up and down the eastern seaboard if weather and atmospheric conditions cooperate to provide a spectacular viewing opportunity to the most populated region in North America.

The Cygnus spacecraft for the OA-5 mission is named the S.S. Alan G. Poindexter in honor of former astronaut and Naval Aviator Captain Alan Poindexter.

NASA WALLOPS FLIGHT FACILITY, VA – After a two year stand down, an upgraded commercial Antares rocket was rolled out to the NASA Wallops launch pad on Virginia’s eastern shore and raised to its launch position today in anticipation of a spectacular Sunday night liftoff, Oct. 16, to the International Space Station (ISS) on a critical resupply mission for NASA.

Blastoff of the re-engined Orbital ATK Antares rocket is slated for 8:03 p.m. EDT on Oct. 16 from the Mid-Atlantic Regional Spaceport pad 0A at NASA’s Wallops Flight Facility on Virginia’s picturesque Eastern shore.

The two year lull in Antares launches followed the rockets immediate grounding after its catastrophic failure just moments after liftoff on Oct. 28, 2014 that doomed the Orb-3 resupply mission to the space station – as witnessed by this author.

Officials had to postpone this commercial resupply mission – dubbed OA-5 – from mid-week due to Cat 3 Hurricane Nicole which slammed into Bermuda yesterday, Oct. 13, packing winds of about 125 mph, and is home to a critical NASA launch tracking station.

After the storm passed, engineers found the tracking station only suffered minor damage – so the GO was given to proceed with preparation for Sunday’s nighttime launch.

“Repairs to the station have been made and the team is currently readying to support the launch,” according to NASA officials.

Engineers are still testing the station to ensure its readiness.

“The Bermuda site provides tracking, telemetry and flight terminations support for Antares launches from NASA’s Wallops Flight Facility on Virginia’s Eastern Shore. Final testing is scheduled to be conducted the morning of Oct. 15 prior to the launch readiness review later that day.”

First Antares Liftoff in 2 Years Targeted for Dazzling Nighttime Leap from Virginia on Oct. 13

The first Antares rocket liftoff in nearly two years is now being targeted for Oct. 13 on what is sure to be a dazzling nighttime leap from NASA’s Virginia launch base – and potentially offering a thrilling skyshow to millions of US East Coast spectators, if all goes well.

Top NASA and Orbital ATK managers formally approved the launch of the upgraded commercial Antares rocket for next Thursday evening, Oct. 13, on a cargo resupply mission to the International Space Station (ISS). The announcement follows on the heels of a successful joint pre-launch Flight Readiness Review (FRR).

Blastoff of the Orbital ATK Antares rocket is slated for 9:13 p.m. EDT on Oct. 13 from the Mid-Atlantic Regional Spaceport pad 0A at NASA’s Wallops Flight Facility on Virginia’s picturesque Eastern shore.

Antares will be rolled out to the pad 0A on Oct. 11 – two days prior to the anticipated launch date.

Antares will carry the Orbital OA-5 Cygnus cargo freighter to orbit on a flight bound for the ISS and its multinational crew of astronauts and cosmonauts.

The 14 story tall commercial Antares rocket also will launch for the first time in the upgraded 230 configuration – powered by new Russian-built first stage engines.

For the OA-5 mission, the Cygnus advanced maneuvering spacecraft will be loaded with approximately 2,400 kg (5,290 lbs.) of supplies and science experiments for the International Space Station (ISS).

“Cygnus is loaded with the Saffire II payload and a nanoracks cubesat deployer,” Frank DeMauro, Orbital ATK Cygnus program manager, told Universe Today in a interview.

If Cygnus launches as planned on Oct. 13, it is scheduled to arrive at the station on Sunday, Oct. 16. Astronauts will use the space station’s robotic arm to grapple Cygnus at approximately about 6:45 a.m. EDT and berth it to the bottom of the station’s Unity module.

NASA TV will provide live coverage of the launch as well as the rendezvous and grappling activities.

Orbital ATK’s Antares commercial rocket had to be overhauled with the completely new RD-181 first stage engines following the destruction of the Antares rocket and Cygnus supply ship two years ago.

In light of the grounding of the SpaceX Falcon 9 and Dragon cargo flights following the catastrophic Sept.1 launch pad disaster, and the catastrophic Antares launch failure in Oct. 2014, this Orbital ATK mission becomes more critical than ever to keep that station stocked and fully operational for the resident crews with a reliable American supply train.

In the meantime, Orbital ATK has successfully resumed launches of their Cygnus cargo freighters to the ISS utilizing the United Launch Alliance (ULA) Atlas V rocket as an interim measure until Antares is returned to flight status

They utilized the ULA Atlas V rocket to successfully deliver two Cygnus vessels to the ISS on the OA-4 flight in Dec 2015 and OA-6 flight in March 2016.

Watch for Ken’s continuing Antares/Cygnus mission and launch reporting. He will be reporting from on site at NASA’s Wallops Flight Facility, VA during the launch campaign.
