KENNEDY SPACE CENTER, FL – Orbital ATK’s Cygnus supply ship soared to space from the Florida Space Coast at lunchtime today, Tuesday, April 18, drenched in sunshine and carrying the ‘SS John Glenn’ loaded with over three and a half tons of precious cargo – bound for the multinational crew residing aboard the International Space Station (ISS).
Just like clockwork, Orbital ATK’s seventh cargo delivery flight to the station launched right on time at 11:11 a.m. EDT Tuesday at the opening of the launch window atop a United Launch Alliance Atlas V rocket from Space Launch Complex 41 on Cape Canaveral Air Force Station in Florida.
The ‘SS John Glenn’ Cygnus resupply spacecraft was manufactured by NASA commercial cargo provider Orbital ATK. The vehicle is also known alternatively as the Cygnus OA-7 or CRS-7 mission.
“This was a great launch,” said Joel Montalbano, NASA’s deputy manager of the International Space Station program, at the post launch media briefing at NASA’s Kennedy Space Center.
‘We have a vehicle on its way to the ISS.”

Huge crowds gathered at public viewing areas ringing Cape Canaveral and offering spectacular views from Playalinda Beach to the north, the inland waterway and more beautiful space coast beaches to the south.
Near perfect weather conditions and extended views of the rocket roaring to orbit greeted all those lucky enough to be on hand for what amounts to a sentimental third journey to space for American icon John Glenn.
The launch was carried live on NASA TV with extended expert commentary. Indeed this launch coverage was the final one hosted by NASA commentator George Diller- the longtime and familiar ‘Voice of NASA’ – who is retiring from NASA on May 31.
The serene sky blue skies with calm winds and moderate temperatures were punctuated with wispy clouds making for a thrilling spectacle as the rocket accelerated northeast up the US East Coast on a carefully choreographed trajectory to the massive orbiting outpost.
“The status of the spacecraft is great!” said Frank Culbertson, a former shuttle and station astronaut and now Orbital ATK’s Space Systems Group president.

The mission is named the ‘S.S. John Glenn’ in tribute to legendary NASA astronaut John Glenn – the first American to orbit Earth back in February 1962.
Glenn was one of the original Mercury Seven astronauts selected by NASA. At age 77 he later flew a second mission to space aboard Space Shuttle Discovery- further cementing his status as a true American hero.
Glenn passed away in December 2016 at age 95. He also served four terms as a U.S. Senator from Ohio.
A picture of John Glenn in his shuttle flight suit and a few mementos are aboard.
After a four day orbital chase Cygnus will arrive in the vicinity of the station on Saturday, April 22.
“It will be captured at about 6 a.m. EDT Saturday,” Montalbano elaborated.
Expedition 51 astronauts Thomas Pesquet of ESA (European Space Agency) and Peggy Whitson of NASA will use the space station’s Canadian-built robotic arm to grapple Cygnus, about 6:05 a.m. Saturday.
They will use the arm to maneuver and berth the unmanned vehicle to the Node-1 Earth-facing nadir port on the Unity module.
Cygnus will remain at the space station for about 85 days until July before its destructive reentry into Earth’s atmosphere, disposing of several thousand pounds of trash.
The countdown for today’s launch of the 194-foot-tall two stage United Launch Alliance (ULA) rocket began when the rocket was activated around 3 a.m. The rocket was tested during a seven-hour long countdown.
This is the third Cygnus to launch on an Atlas V rocket from the Cape. The last one launched a year ago on March 24, 2016 during the OA-6 mission. The first one launched in December 2015 during the OA-4 mission. Each Cygnus is named after a deceased NASA astronaut.
“We’re building the bridge to history with these missions,” said Vernon Thorp, ULA’s program manager for Commercial Missions. “Every mission is fantastic and every mission is unique. At the end of the day every one of these missions is critical.”
“The Atlas V performed beautifully,” said Thorpe at the post launch briefing.
The other Cygnus spacecraft have launched on the Orbital ATK commercial Antares rocket from NASA Wallops Flight Facility on Virginia’s eastern shore.
Cygnus OA-7 is loaded with 3459 kg (7626 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 51 and 52 crews. The total volumetric capacity of Cygnus exceeds 27 cubic meters.
The official OA-7 payload manifest includes the following:
TOTAL PRESSURIZED CARGO WITH PACKAGING: 7,442.8 lbs. / 3,376 kg
• Science Investigations 2,072.3 lbs. / 940 kg
• Crew Supplies 2,103.2 lbs. / 954 kg
• Vehicle Hardware 2,678.6 lbs. / 1,215 kg
• Spacewalk Equipment 160.9 lbs. / 73 kg
• Computer Resources 4.4 lbs. / 2 kg
• Russian Hardware 39.7 lbs. / 18 kg
UNPRESSURIZED CARGO (CubeSats) 183 lbs. / 83 kg
The Orbital ATK Cygnus CRS-7 (OA-7) mission launched aboard an Atlas V Evolved Expendable Launch Vehicle (EELV) in the 401 configuration vehicle. This includes a 4-meter-diameter payload fairing in its longest, extra extended configuration (XEPF) to accommodate the enhanced, longer Cygnus variant being used.
“ULA is excited to be a part of the team that delivered such an important payload to astronauts aboard the ISS,” said Gary Wentz, ULA vice president of Human and Commercial Systems, in a statement.
“Not only are we delivering needed supplies as the first launch under our new RapidLaunch™ offering, but we are truly honored to launch a payload dedicated to John Glenn on an Atlas V, helping to signify the gap we plan to fill as we start launching astronauts from American soil again in 2018.”
The first stage of the Atlas V booster is powered by the RD AMROSS RD-180 engine. There are no side mounted solids on the first stage. The Centaur upper stage is powered by the Aerojet Rocketdyne RL10C-1 engine.
Overall this is the 71st launch of an Atlas V and the 36th utilizing the 401 configuration.
The 401 is thus the workhorse version of the Atlas V and accounts for half of all launches.

KENNEDY SPACE CENTER, FL – The ‘SS John Glenn’ cargo freighter stands proudly poised for launch at pad 41 from the Florida Space Coast on Tuesday April 18, loaded with a stash of nearly 4 tons of science investigations and essential supplies atop a United Launch Alliance Atlas V rocket destined for the multinational crew aboard the International Space Station (ISS).
The lunchtime liftoff of the ‘SS John Glenn’ Cygnus resupply spacecraft manufactured by NASA commercial cargo provider Orbital ATK is slated for 11:11 a.m. EDT Tuesday, April 18 from Space Launch Complex 41 on Cape Canaveral Air Force Station, FL.
The US cargo ships provided by NASA suppliers Orbital ATK and SpaceX every few months act as NASA’s essential railroad to space. And they are vital to operating the station with a steady stream of new research experiments as well as essential hardware, spare parts, crew supplies, computer, maintenance and spacewalking equipment as well food, water, clothing, provisions and much more.
The launch window lasts 30 minutes and runs from 11:11-11:41 a.m. EDT April 18.
Excited spectators are gathering from near and far and Tuesday’s weather outlook is spectacular so far.

Science plays a big role in this mission in tribute named in tribute to John Glenn. Over one third of the payload loaded aboard Cygnus involves science.
“The new experiments will include an antibody investigation that could increase the effectiveness of chemotherapy drugs for cancer treatment and an advanced plant habitat for studying plant physiology and growth of fresh food in space,” according to NASA.
The astronauts will grow food in space, including Arabidopsis and dwarf wheat, in an experiment that could lead to providing nutrition to astronauts on a deep space journey to Mars.
“Another new investigation bound for the U.S. National Laboratory will look at using magnetized cells and tools to make it easier to handle cells and cultures, and improve the reproducibility of experiments. Cygnus also is carrying 38 CubeSats, including many built by university students from around the world as part of the QB50 program. The CubeSats are scheduled to deploy from either the spacecraft or space station in the coming months.”
Also aboard is the ‘Genes in Space-2’ experiment. A high school student experiment from Julian Rubinfien of Stuyvescent High School, New York City, to examine accelerated aging during space travel. This first experiment will test if telomere-like DNA can be amplified in space with a small box sized experiment that will be activated by station astronauts.
The Saffire III payload experiment will follow up on earlier missions to study the development and spread of fire and flames in the microgravity environment of space. The yard long experiment is located in the back of the Cygnus vehicle. It will be activated after Cygnus departs the station roughly 80 days after berthing. It will take a few hours to collect the data for transmission to Earth.

From a weather standpoint, Tuesday’s launch outlook is outstanding at this time.
According to meteorologists with the U.S. Air Force 45th Weather Squadron we are forecasting a 90 percent chance of “go” conditions at the 11:11 a.m. EDT launch time. The primary concern is for the possibility of cumulus clouds.
The forecast calls for temperatures of 75-76° F with on-shore winds peaking below 10 knots during the countdown.
In the event of a delay for any reason related to weather or technical issues a backup launch opportunity exists for Wednesday, April 19, and also looks promising.
The AF is also predicting the same 90 percent chance of “go” conditions at launch time. With the primary concern again being for the possibility of cumulus clouds.

KENNEDY SPACE CENTER, FL – The next Cygnus cargo ship launching to the International Space Station (ISS) has been christened the ‘S.S. John Glenn’ to honor legendary NASA astronaut John Glenn – the first American to orbit the Earth back in February 1962.
John Glenn was selected as one of NASA’s original seven Mercury astronauts chosen at the dawn of the space age in 1959. He recently passed away on December 8, 2016 at age 95.
The naming announcement was made by spacecraft builder Orbital ATK during a ceremony with the ‘S.S. John Glenn’, held inside the Kennedy Space Center (KSC) clean room facility where the cargo freighter is in the final stages of flight processing – and attended by media including Universe Today on Thursday, March 9.
“It is my humble duty and our great honor to name this spacecraft the S.S. John Glenn,” said Frank DeMauro, vice president and general manager of Orbital ATK’s Advanced Programs division, during the clean room ceremony in the inside the Payload Hazardous Servicing Facility high bay at NASA’s Kennedy Space Center in Florida.

The S.S. John Glenn is scheduled to liftoff as the Orbital ATK Cygnus OA-7 spacecraft for NASA on a United Launch Alliance (ULA) Atlas V rocket launch no earlier than March 21 from Space launch Complex-41 (SLC-41) on Cape Canaveral Air Force Station, Florida.
The space station resupply mission dubbed Cygnus OA-7 is dedicated to Glenn and his landmark achievement as the first American to orbit the Earth on Feb. 20, 1962 and his life promoting science, human spaceflight and education.
“John Glenn was probably responsible for more students studying math and science and being interested in space than anyone,” said former astronaut Brian Duffy, Orbital ATK’s vice president of Exploration Systems, during the clean room ceremony on March 9.
“When he flew into space in 1962, there was not a child then who didn’t know his name. He’s the one that opened up space for all of us.”

Glenn’s 3 orbit mission played a pivotal role in the space race with the Soviet Union at the height of the Cold War era.
“He has paved the way for so many people to follow in his footsteps,” said DeMauro.
All of Orbital ATK’s Cygnus freighters have been named after deceased American astronauts.
Glenn is probably America’s most famous astronaut in addition to Neil Armstrong, the first man to walk on the moon during Apollo 11 in 1969.
John Glenn went on to become a distinguished U.S. Senator from his home state of Ohio on 1974. He served for 24 years during 4 terms.
He later flew a second mission to space aboard the Space Shuttle Discovery in 1998 as part of the STS-95 crew at age 77. Glenn remains the oldest person ever to fly in space.
“Glenn paved the way for America’s space program, from moon missions, to the space shuttle and the International Space Station. His commitment to America’s human space flight program and his distinguished military and political career make him an ideal honoree for the OA-7 mission,” Orbital ATK said in a statement.

“The OA-7 mission is using the Enhanced Cygnus Pressurized Cargo Module (PCM) to deliver cargo to the International Space Station,” said DeMauro.
Cygnus will carry 7,700 pounds (3500 kg) of cargo to the station with a total volumetric capacity of 27 cubic meters.
“All these teams have worked extremely hard to get this mission to this point and we are looking forward to a great launch.”

KENNEDY SPACE CENTER, FL – NASA’s constellation of experimental hurricane monitoring CYGNSS microsatellites was successfully air launched by the unique Orbital ATK winged Pegasus rocket on Thursday, Dec 15 – opening a new era in weather forecasters ability to measure the buildup of hurricane intensity in the tropics from orbit that will eventually help save lives and property from impending destructive storms here on Earth.
The agency’s innovative Cyclone Global Navigation Satellite System (CYGNSS) earth science mission was launched at 8:37 a.m. EST, Dec. 15, aboard a commercially developed Orbital ATK Pegasus XL rocket from a designated point over the Atlantic Ocean off the east coast of Florida.
Officials just announced this morning Dec. 16 that the entire fleet is operating well.
“NASA confirmed Friday morning that all eight spacecraft of its latest Earth science mission are in good shape.”
“The launch of CYGNSS is a first for NASA and for the scientific community,” said Thomas Zurbuchen, associate administrator for the agency’s Science Mission Directorate in Washington.
“As the first orbital mission in our Earth Venture program, CYGNSS will make unprecedented measurements in the most violent, dynamic, and important portions of tropical storms and hurricanes.”

Late Thursday, NASA announced that contact had been made with the entire fleet of eight small satellites after they had been successfully deployed and safely delivered to their intended position in low Earth orbit.
“We have successfully contacted each of the 8 observatories on our first attempt,” announced Chris Ruf, CYGNSS principal investigator with the Department of Climate and Space Sciences and Engineering at the University of Michigan.
“This bodes very well for their health and “status, which is the next thing we will be carefully checking with the next contacts in the coming days.”
The three stage Pegasus XL rocket housing the CYGNSS earth science payload inside the payload fairing had been carried aloft to 39,000 feet by an Orbital ATK L-1011 Tristar and dropped from the aircrafts belly for an air launch over the Atlantic Ocean and about 110 nautical miles east-northeast of Daytona Beach.

The L-1011 nicknamed Stargazer took off at about 7:30 a.m. EST from NASA’s Skid Strip on Cape Canaveral Air Force Station in Florida as the media including myself watched the events unfold under near perfect Sunshine State weather with brilliantly clear blue skies.
After flying to the dropbox point – measuring about 40-miles by 10-miles (64-kilometers by 16-kilometers) – the Pegasus rocket was dropped from the belly, on command by the pilot, for a short freefall of about 5 seconds to initiate the launch sequence and engine ignition.
Pegasus launches horizontally in midair with ignition of the first stage engine burn, and then tilts up to space to begin the approximate ten minute trek to LEO.
The rocket launch and satellite release when exactly as planned with no hiccups.
It’s a beautiful day, with gorgeous weather,” said NASA CYGNSS launch director Tim Dunn. “We had a nominal flyout, and all three stages performed beautifully. We had no issues at all with launch vehicle performance.”
Deployment of the first pair of CYGNSS satellites in the eight satellite fleet started just 13 minutes after launch. The other six followed sequentially staged some 30 seconds apart.
“It’s a great event when you have a successful spacecraft separation – and with eight microsatellites, you get to multiply that times eight,” Dunn added.
“The deployments looked great — right on time,” said John Scherrer, CYGNSS Project Manager at the Southwest Research Institute and today’s CYGNSS mission manager, soon after launch.
“We think everything looks really, really good. About three hours after launch we’ll attempt first contact, and after that, we’ll go through a series of four contacts where we hit two [observatories] each time, checking the health and status of each spacecraft,” Scherrer added several prior to contact..
CYGNSS small satellite constellation launch came after a few days postponement due to technical issues following an aborted attempt on Monday, when the release mechanism failed and satellite parameter issues cropped up on Tuesday, both of which were rectified.
NASA’s innovative Cyclone Global Navigation Satellite System (CYGNSS) mission is expected to revolutionize hurricane forecasting by measuring the intensity buildup for the first time.
“The CYGNSS constellation consists of eight microsatellite observatories that will measure surface winds in and near a hurricane’s inner core, including regions beneath the eyewall and intense inner rainbands that previously could not be measured from space,” according to a NASA factsheet.
CYGNSS is an experimental mission to demonstrate proof-of-concept that could eventually turn operational in a future follow-up mission if the resulting data returns turn out as well as the researchers hope.
The CYGNSS constellation of 8 identical satellites works in coordination with the Global Positioning System (GPS) satellite constellation.
The eight satellite CYGNSS fleet “will team up with the Global Positioning System (GPS) constellation to measure wind speeds over Earth’s oceans and air-sea interactions, information expected to help scientists better understand tropical cyclones, ultimately leading to improved hurricane intensity forecasts.”
They will receive direct and reflected signals from GPS satellites.
“The direct signals pinpoint CYGNSS observatory positions, while the reflected signals respond to ocean surface roughness, from which wind speed is retrieved.”

The $157 million fleet of eight identical spacecraft comprising the Cyclone Global Navigation Satellite System (CYGNSS) system were all delivered to low Earth orbit by the Orbital ATK Pegasus XL rocket.
The nominal mission lifetime for CYGNSS is two years but the team says they could potentially last as long as five years or more if the spacecraft continue functioning.

Pegasus launches from the Florida Space Coast are infrequent. The last once took place over 13 years ago in late April 2003 for the GALEX mission.
Typically they take place from Vandenberg Air Force Base in California or the Reagan Test Range on the Kwajalein Atoll.

CYGNSS counts as the 20th Pegasus mission for NASA and the 43rd mission overall for Orbital ATK.
The CYGNSS spacecraft were built by Southwest Research Institute in San Antonio, Texas.
The solar panels and spacecraft dispenser were built by Sierra Nevada Corporation (SNC).
Each one weighs approx 29 kg. The deployed solar panels measure 1.65 meters in length.
The solar panels measure 5 feet in length and will be deployed within about 15 minutes of launch.
“We are thrilled to be a part of a project that helps gain better hurricane data that can eventually help keep a lot of people safe, but from a business side, we are also glad we could help SwRI achieve their mission requirements with better performance and lower cost and risk,” said Bryan Helgesen, director of strategy and business development for Space Technologies in SNC’s Space Systems business area, in a statement.

KENNEDY SPACE CENTER, FL – Monday’s (Dec. 12) planned launch of NASA’s innovative Cyclone Global Navigation Satellite System (CYGNSS) hurricane microsatellite fleet was aborted when a pump in the hydraulic system that releases the Pegasus air-launch booster from its L-1011 carrier aircraft failed in flight. UPDATE: launch delayed to Dec 15, story revised
NASA and Orbital ATK confirmed this afternoon that the launch of the Orbital ATK commercial Pegasus-XL rocket carrying the CYGNSS small satellite constellation has been rescheduled again to Thursday, Dec. 15 at 8:26 a.m. EST from a drop point over the Atlantic Ocean.
Late last night the launch was postponed another day from Dec. 14 to Dec. 15 to solve a flight parameter issue on the CYGNSS spacecraft. New software was uploaded to the spacecraft that corrected the issue, NASA officials said.
“NASA’s launch of CYGNSS spacecraft is targeted for Thursday, Dec. 15,” NASA announced.
“We are go for launch of our #Pegasus rocket carrying #CYGNSS tomorrow, December 15 from Cape Canaveral Air Force Station,” Orbital ATK announced.

“The CYGNSS constellation consists of eight microsatellite observatories that will measure surface winds in and near a hurricane’s inner core, including regions beneath the eyewall and intense inner rainbands that previously could not be measured from space,” according to a NASA factsheet.
Despite valiant efforts by the flight crew to restore the hydraulic pump release system to operation as the L-1011 flew aloft near the Pegasus drop zone, they were unsuccessful before the launch window ended and the mission had to be scrubbed for the day by NASA Launch Director Tim Dunn.

The hydraulic release system passed its pre-flight checks before takeoff of the Stargazer.
“Launch of the Pegasus rocket was aborted due to an issue with the launch vehicle release on the L-1011 Stargazer. The hydraulic release system operates the mechanism that releases the Pegasus rocket from the carrier aircraft. The hydraulic system functioned properly during the pre-flight checks of the airplane,” said NASA.
A replacement hydraulic pump system component was flown in from Mojave, California, and successfully installed and checked out. Required crew rest requirements were also met.

The weather forecast from the Air Force’s 45th Weather Squadron at Cape Canaveral has significantly increased to predicting a 90% chance of favorable conditions on Thursday, Dec. 15.
The primary weather concerns are for flight cumulus clouds.
The Pegasus rocket cannot fly through rain or clouds due to a negative impact and possible damage on the rocket’s thermal protection system (TPS).
In the event of a delay, the range is also reserved for Friday, Dec. 16 where the daily outlook remains at a 90% chance of favorable weather conditions.

After Stargazer takes off from the Skid Strip early Thursday around 6:30 a.m. EST, it will fly north to a designated drop point box about 126 miles east of Daytona Beach, Florida over the Atlantic Ocean. The crew can search for a favorable launch point if needed, just as they did Monday morning.
The drop box point measures about 40-miles by 10-miles (64-kilometers by 16-kilometers). The flight crew flew through the drop box twice on Monday, about a half an hour apart, as they tried to repair the hydraulic system by repeatedly cycling it on and off and sending commands.
“It was not meeting the prescribed launch release pressures, indicating a problem with the hydraulic pump,” said NASA CYGNSS launch director Tim Dunn.
“Fortunately, we had a little bit of launch window to work with, so we did a lot of valiant troubleshooting in the air. As you can imagine, everyone wanted to preserve every opportunity to have another launch attempt today, so we did circle around the race once, resetting breakers on-board the aircraft, doing what we could in flight to try to get that system back into function again.”
The rocket will be dropped for a short freefall of about 5 seconds to initiate the launch sewuence. It launches horizontally in midair with ignition of the first stage engine burn, and then tilts up to space to begin the trek to LEO.

KENNEDY SPACE CENTER, FL – An exciting new chapter in hurricane monitoring and forecasting intensity prediction is due to open Monday morning at NASA’s Kennedy Space Center when a new constellation of microsatellites dubbed CYGNSS are slated to be deployed from an air-launched Orbital ATK Pegasus XL rocket.
The fleet of eight identical spacecraft comprising the Cyclone Global Navigation Satellite System (CYGNSS) system will be delivered to Earth orbit by an Orbital ATK Pegasus XL rocket.
The Pegasus/CYGNSS vehicle is attached to the bottom of the Orbital ATK L-1011 Stargazer carrier aircraft.
“The CYGNSS constellation consists of eight microsatellite observatories that will measure surface winds in and near a hurricane’s inner core, including regions beneath the eyewall and intense inner rainbands that previously could not be measured from space,” according to a NASA factsheet.
The data obtained by studying the inner core of tropical cyclones “will help scientists and meteorologists better understand and predict the path of a hurricane.”
Improved hurricane forecasts can help protect lives and mitigate property damage in coastal areas under threat from hurricanes and cyclones.

CYGNSS is an experimental mission to demonstrate proof-of-concept that could eventually turn operational in a future follow-up mission if the resulting data returns turn out as well as the researchers hope.
The Pegasus XL rocket with the eight observatories are tucked inside the nose cone will be air-launched by dropping them from the belly of Orbital’s modified L-1011 carrier aircraft, nicknamed Stargazer, after taking off from the “Skid Strip” runway at Cape Canaveral Air Force Station in Florida.
If all goes well, the rocket will be dropped from Stargazer’s belly for the launch currently planned for Monday, Dec. 12 at 8:24 a.m. EST.
Five seconds after the rocket is deployed at 39,000 feet, the solid fueled Pegasus XL first stage engine with ignite for the trip to low earth orbit.
They will be deployed from a dispenser at an altitude of about 510 km and an inclination of 35 degrees above the equator.

Back in October, the Cygnus CRS OA-5 mission (aka. the Orbital Sciences CRS Flight 5) rendezvoused with the International Space Station. As part of Orbital ATK craft’s sixth Commercial Resupply mission to the ISS, the unmanned spacecraft spent the past month berthed with the station, delivering 2,268 kg (5,000 pounds) of cargo and experiments and taking on 1,120 kilograms (2,469 pounds) of trash.
As of this Monday, November 21st, the spacecraft – named the “S.S. Alan Poindexter” in honor of the deceased Space Shuttle commander who died in 2012 – separated from the station’s Unity Module, and will spend the next week performing standalone operations. These have included the much-anticipated Spacecraft Fire Experiment 2 (aka. Saffire-II), which is managed by NASA’s Glenn Research Center.
This experiment, which began just five hours after the shuttle detached from the station (and after it conducted an orbit-raising maneuver), involved the Cygnus controllers deliberately starting a fire inside the spacecraft’s pressurized cabin. The purpose of this was to investigate how fuel combustion works and fires grow in a microgravity environment.

How fire behaves in space is one of the least understood hazards facing crewed exploration. Until now, research has been limited, and for obvious reasons. Starting a controlled fire in a microgravity environment, especially when you don’t even know how it will behave, is an extremely risky venture. All previous tests that were carried out were severely restricted in size, and yielded very little information.
In contrast, the uncrewed portion of the Cygnus mission offers NASA scientists a rare opportunity to conduct a microgravity fire test aboard a spacecraft. Not only are they hoping to address how fires can ignite, but also how large they can grow in microgravity, how they may consume materials the spacecraft is built from, and eventually die.
As Jitendra Joshi, the technology integration lead for NASA’s Advanced Exploration Systems division, said in an interview with Spaceflight Now, such tests are critical for developing fire countermeasures:
“One of the least understood risks in space is how fire propagates (and) starts. How do you control the fire? How do you detect the fire? All these things. You can’t call 911 like on Earth to come help you.”
In addition to being pressurized, the inside of the Cygnus spacecraft also contained samples of material that are commonly found aboard the ISS. NASA was also sure to include materials that would be included in future tests of the Orion capsule, since such tests are of extreme importance to their “Journey to Mars” and other long-range, long-duration missions.
This was the second experiment conducted as part of the Saffire program, which is managed by NASA’s Advanced Exploration Systems Division, part of the Glenn Research Center. It follows on the heels of the highly successful Saffire-I experiment, which took place in July of 2016. In that experiment, samples of a cotton-fiberglass blend were ignited inside an enclosure aboard a Cygnus vehicle, which consisted of a flow duct and avionics bay.
The samples themselves measured 0.4 meter wide by 1 m long, and were ignited by a hot wire inside an enclosure measuring half a meter wide, 1 meter deep and 1.3 meter long. Prior to this experiment, the largest fire experiment that had ever been conducted in space was about the size of an index card.
The Saffire-II experiment (the second of three proposed fire tests) began just after 18:15 Eastern Time (23:15 UTC ) on November 21st, as the first of nine samples was ignited aboard the craft. This time around, the samples included a cotton-fiberglass blend, Nomex (a flame resistant material used commonly aboard spacecraft), and the same acrylic glass that is used for spacecraft windows.
The nine samples burned for a total of two hours before dying out, and yielded much useful information. As Gary Ruff, Saffire’s project manager, said in a previous NASA press release:
“A spacecraft fire is one of the greatest crew safety concerns for NASA and the international space exploration community. Saffire is all about gaining a better understanding of how fire behaves in space so NASA can develop better materials, technologies and procedures to reduce crew risk and increase space flight safety.”
The third and final experiment for the Spacecraft Fire Experiment series (Saffire-III) is scheduled to take place during the OA-7 mission, which is scheduled to take place in March of 2017. With all three experiments complete, NASA hopes to have accumulated enough data to help guide the selection and construction of future spacecraft, subsystems and instruments.
They also hope that these experiments will help mission planners come up with operational protocols designed to address fires during future crewed missions. These will be especially handy during missions where astronauts don’t have the option of exiting to a docked spacecraft and returning to Earth (as they do aboard the ISS).
The Cygnus craft is now moving on to deploy the four LEMUR CubeSats, which will happen on Friday, November 25th. These CubeSats are part of a growing community of satellites that provide global ship tracking and weather monitoring services.
Following this, Cygnus will remain in orbit for two more days before conducting two burns that will cause it to deorbit and burn up in out atmosphere – which will take place on Sunday, November 27th.

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.

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.
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 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.
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.

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 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 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.
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 experiment 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.
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.

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.
