Four days after liftoff the SS John Glenn finally arrived at the station as planned Saturday morning April 22 following a carefully choreographed series of thruster maneuvers this past week.
The private Cygnus resupply vessel is carrying nearly four tons of science and supplies crammed inside for the five person multinational Expedition 51 crew.
After reaching the vicinity of the space station overnight Saturday, Cygnus was successfully captured by astronaut crew members Thomas Pesquet of ESA (European Space Agency) and Expedition 51 Station Commander Peggy Whitson of NASA at 6:05 a.m. EDT using the space station’s 57.7-foot (17.6-meter) Canadian-built Canadarm2 robotic arm.
The SS John Glenn Cygnus vehicle counts as Orbital ATK’s seventh cargo delivery flight to the station.
The vehicle is also known alternatively as the Cygnus OA-7 or CRS-7 mission.
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.

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.

Blastoff of the S.S. John Glenn on the OA-7 or CRS-7 flight counts as Orbital ATK’s seventh contracted commercial resupply services mission to the ISS for NASA.
The ‘S.S. John Glenn’ is named in honor of legendary NASA astronaut John Glenn – the first American to orbit Earth back in February 1962.
If you can’t attend in person, there are a few options to watch online.
NASA’s Atlas V/Cygnus CRS-7 launch coverage will be broadcast on NASA TV and the NASA launch blog beginning at 10 AM, Tuesday morning.
A ULA webcast will be available starting at 10 a.m. at: www.ulalaunch.com
And for the first time ever you can also watch the launch live via a live 360 stream on the NASA Television YouTube channel. The 360 degree broadcast starts about 10 minutes prior to lift off at:

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.

The rocket was rolled out to pad 41 at about 9 a.m. EDT this morning Monday April 17, in a process that takes about 25 minutes
The rocket and spacecraft passed the Launch Readiness Review held by United Launch Alliance and Orbital ATK on April 15. Launch managers from ULA, Orbital ATK and NASA determined all is ready for Tuesday’s targeted launch to the ISS.
OA-7 is loaded with 3500 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 51 and 52 crews. The total volumetric capacity of Cygnus exceeds 27 cubic meters.

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 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.”

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.
“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.”

At the time, Orbital ATK officials told Universe Today they were working towards efforts for the next Cygnus to launch from Wallops on the OA-7 resupply mission sometime next spring – tentatively in March 2017.
“Following a successful Antares launch for the recent OA-5 Commercial Resupply Services mission and subsequent rendezvous and berthing of the Cygnus spacecraft with the International Space Station, Orbital ATK has responded to NASA’s needs for enhanced schedule assurance for cargo deliveries and maximum capacity of critical supplies to the space station in 2017 by once again partnering with United Launch Alliance to launch Cygnus aboard an Atlas V for the upcoming OA-7 mission in the spring timeframe,” Orbital ATK said in a statement to Universe Today.
“We anticipate the earliest we may need a NASA commercial resupply mission is early 2017. We mutually agreed with Orbital ATK to use an Atlas V for the company’s seventh contracted cargo resupply mission to the space station in the spring. We will provide additional details at a later date,” NASA HQ public affairs told Universe Today for this story.

The ULA Atlas V would launch from Space Launch Complex-41 on Cape Canaveral Air Force Station.
Cygnus OA-7 will be processed and loaded at NASA’s Kennedy Space Center in Florida for later integration with the Atlas V.

When Cygnus launches on Atlas from KSC it can carry roughly over 300 pounds more to orbit vs. using Antares from Virginia.
The Cygnus OA-5 spaceship is currently still berthed at the million pound station and carried about 5100 pounds to orbit.
Thus the ISS is in good shape overall at this time from a supplies standpoint.
“Supplies and research investigations are at good levels aboard the International Space Station. In addition to Orbital ATK’s recent successful commercial resupply services mission to station in October, a Russian Progress and Japanese HTV will carry additional cargo to the orbiting laboratory before the end of the year,” NASA public affairs elaborated for this story.

Last month’s ‘Return to Flight’ liftoff of the upgraded Antares took place two years after its catastrophic failure moments after launch on October 28, 2014 with another Cygnus cargo ship bound for the International Space Station (ISS) that was destroyed along with all its precious contents.
NASA must have a robust and steady train of cargo ships flying to the ISS to keep it fully operational and stocked with research and provisions for the international crews to maximize the stations science output.
“NASA is continuously working with all our partners on range availability, space station traffic and other factors to ensure we operate station in a safe and effective way as we use it for preparing for longer duration missions farther into the solar system,” NASA PAO told me.
The Atlas V built by competitor United Launch Alliance (ULA) enjoys a 100% record of launch success and was recently employed by Orbital ATK to launch a pair of Cygnus vessels to the International Space Station in the past year – in Dec. 2015 on the OA-4 mission and March 2016 on the OA-6 mission.
Orbital ATK contracted ULA to launch Cygnus spacecraft to the ISS as an interim measure to fulfill their obligations to NASA to keep the station fully operational.
Orbital ATK Vice President Frank Culbertson had previously told me that Orbital ATK could readily launch future Cygnus spaceships on the ULA Atlas V again, if the need arose.
Seeking some near term launch stability NASA has apparently decided that that need has now arisen.
Both Atlas/Cygnus cargo missions went off without a hitch and provide a ready and working template for the upcoming OA-7 cargo ship to be processed again at KSC and launched from Cape Canaveral in the spring of 2017.
Orbital ATK says that follow on Cygnus craft will again return to the Antares rocket for Virginia launches later in 2017.
“Orbital ATK’s remaining missions to be conducted in 2017 and 2018 under the CRS-1 contract will launch aboard the company’s Antares rockets from NASA Wallops Flight Facility in Virginia.”

Altogether a trio of Cygnus vessels might launch in 2017.
“The company will be ready to support three cargo resupply missions to the station next year, and will work with NASA to finalize the flight schedule,” the company said.
“The schedule provides margin flexibility for the entire Antares workforce, who worked tirelessly for the past several months to prepare and successfully launch the upgraded rocket from Wallops Island on the OA-5 mission.”
Cygnus was designed from the start to launch on a variety of launch vehicles – in addition to Antares.
“This plan also allows NASA to again capitalize on the operational flexibility built into Orbital ATK’s Cygnus spacecraft to assure the space station receives a steady and uninterrupted flow of vital supplies, equipment and scientific experiments.”
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.
It is not clear at this time who will shoulder the added cost of launching Cygnus OA-7 on Atlas instead of Antares.
Watch for Ken’s Antares/Atlas/Cygnus mission and launch reporting. He was reporting from on site at NASA’s Wallops Flight Facility, VA during the OA-5 launch campaign and previously from KSC for the OA-4 and OA-6 liftoffs.

Orbital ATK announced late Tuesday that the company’s Antares medium-class commercial rocket outfitted with new first stage RD-181 engines has successfully completed a test firing of the powerplants.
The 30-second long static test firing took place at 5:30 p.m. Tuesday evening, May 31, at Virginia Space’s Mid-Atlantic Regional Spaceport (MARS) Pad 0A.
The now revamped launch vehicle – dubbed Antares 230 – has been ‘re-engined’ and upgraded with a pair of modern and more powerful first stage engines – the Russian-built RD-181 fueled by LOX/kerosene.
The engine test was conducted using only the first stage of Antares at the MARS Pad 0A at NASA’s Wallops Flight Facility.
“Early indications show the upgraded propulsion system, core stage and launch complex all worked together as planned,” said Mike Pinkston, Orbital ATK General Manager and Vice President, Antares Program.
“Congratulations to the combined NASA, Orbital ATK and Virginia Space team on a successful test.”
Orbital ATK engineers will now “review test data over the next several days to confirm that all test parameters were met”

If all goes well with the intensive data review, the company could launch Antares as soon as July on its next NASA contracted mission – known as OA-5 – to resupply the International Space Station (ISS).
The test involved firing up Antares dual first stage RD-181 engines at full 100% power (thrust) for a scheduled duration of approximately 30 seconds. Hold down restraints kept the rocket firmly anchored at the pad during the test.
The RD-181 replaces the previously used AJ26 which failed moments after liftoff during the last launch on Oct. 28, 2014 resulting in a catastrophic failure of the rocket and the Cygnus cargo freighter.
The RD-181 flight engines are built by Energomash in Russia and had to be tested via the static hot fire test to ensure their readiness.
“They are a good drop in replacement for the AJ26. And they offer 13% higher thrust compared to the AJ26,” said Kurt Eberly, Orbital ATK Antares deputy program manager, in an interview with Universe Today.

As a result of switching to the new RD-181 engines, the first stage also had to be modified to incorporate new thrust adapter structures, actuators, and propellant feed lines between the engines and core stage structure.
So the primary goal was to confirm the effectiveness of the new engines and all the changes in the integrated rocket stage.
“The successful stage test, along with the extensive testing of each new RD-181, gives us further confidence in the first stage propulsion and in moving forward to launch,” said Pinkston.
“We are now focused on the OA-5 mission and launching the enhanced Cygnus spacecraft to the International Space Station on our upgraded, higher-performing Antares rocket.”
The test used the first stage core planned to launch the OA-7 mission from Wallops late this year.
With the engine test is completed, the OA-7 stage will be rolled back to the HIF and a new stage fully integrated with the Cygnus cargo freighter will be rolled out to the pad for the OA-5 ‘Return to Flight’ mission as soon as July.
“Each of the new flight RD-181 engines has undergone hot fire acceptance testing at the manufacturer’s facility prior to being shipped to Orbital ATK. A certification test series was successfully completed in the spring of 2015 where a single engine was test fired seven times, accumulating 1,650 seconds of test time and replicating the Antares flight profile, before being disassembled for inspection,” said Orbital ATK officials.

WALLOPS ISLAND, VA – The soon to be reborn Orbital ATK Antares commercial rocket sporting new first stage engines has been raised at its repaired launch pad on Virginia’s scenic eastern shore for a long awaited test firing of the powerplants. The static test firing is now slated to take place in less than 3 days on Tuesday evening, May 31.
The now revamped launch vehicle – dubbed Antares 230 – has been ‘re-engined’ and upgraded with a pair of modern and more powerful first stage engines – the Russian-built RD-181 fueled by LOX/kerosene.
The engine test will be conducted using only the first stage of Antares at the Mid-Atlantic Regional Spaceport’s Pad-0A at NASA’s Wallops Flight Facility.
The raised rocket with the first stage capped at the top is visible right now at the Wallops pad – as seen in my new photos taken this week.
NASA announced that the static test firing is slated for no earlier than May 31 during a test window that runs from 5 p.m. to 8:15 p.m. EDT. As a contingency, the Wallops range has been reserved for backup test dates that run through June 5 just in case issues crop up.
NASA will not be carrying a live webcast of the test. Rather they will note the completion of the test on the Wallops’ Facebook and Twitter sites.

The test firing will be visible from various public viewing locations in the local Wallops area. However the NASA Wallops Visitor center will not be open.

To prepare for the static hot fire test, Orbital ATK technicians rolled the vehicle on a dedicated multi-wheeled transporter erector launcher from the rockets processing hangar inside the Horizontal Integration Facility at NASA’s Wallops Flight Facility to Virginia Space’s Mid-Atlantic Regional Spaceport Pad-0A about a mile away.
A successful outcome is absolutely crucial for permitting Antares to carry out its ‘Return to Flight’ launch dubbed OA-5 and set for sometime this summer.
“The hot fire will demonstrate the readiness of the rocket’s first stage and the launch pad fueling systems to support upcoming flights,” said NASA officials.
Antares launches ground to a halt following a devastating launch failure 19 months ago which destroyed the rocket and its payload of space station science and supplies for NASA in a huge fireball.
The ‘Return to Flight’ blastoff – which could come as soon as July 2016 – will be the first for the private Antares rocket since that catastrophic launch failure on Oct. 28, 2014, just seconds after liftoff from Wallops. That flight was carrying Orbital ATK’s Cygnus cargo freighter on the critical Orb-3 resupply mission for NASA and the astronauts living and working on the International Space Station (ISS).
The launch mishap was traced to a failure in the AJ26 first stage engine turbopump and caused Antares launches to immediately grind to a halt.
The RD-181 replaces the AJ26. The flight engines are built by Energomash in Russia.
“They are a good drop in replacement for the AJ26. And they offer 13% higher thrust compared to the AJ26,” said Kurt Eberly, Orbital ATK Antares deputy program manager, in an interview with Universe Today.
As a result of switching to the new RD-181 engines, the first stage also had to be modified to incorporate new thrust adapter structures, actuators, and propellant feed lines between the engines and core stage structure.
“This stage test paradigm is a design verification test,” said Eberly.
“After the 30 second test is done we will shut it down and have a pile of data to look at,” Eberly told Universe Today.
“Hopefully it will confirm all our environments and all our models and give us the confidence so we can proceed with the return to flight.”
Technicians have been processing the rocket at the pad to ready it for the test. They also conducted a wet dress rehearsal (WDR) and loaded the propellants like during an actual launch campaign.
The full up engine test follows the WDR.
“After the WDR we will do the stage test,” Eberly explained.
“It is a 30 second test. We will fire up both engines and hit all 3 power levels that we plan to use in flight.”
“We will use the thrust vector controls. So we will move the nozzles and sweep them through sinusoidal sweeps at different frequencies and excite various resonances and look for any adverse interaction between fluid modes and structural modes.”
The test uses the first stage core planned to launch the OA-7 mission from Wallops late this year.

“Orbital ATK is building, testing and flying the Antares rocket and Cygnus cargo spacecraft under NASA’s Commercial Resupply Services contract. NASA initiatives like the cargo resupply contracts are helping develop a robust U.S. commercial space transportation industry with the goal of achieving safe, reliable and cost-effective transportation to and from the International Space Station and low-Earth orbit,” according to NASA.

NASA WALLOPS FLIGHT FACILITY, VA – Assembly and testing of a significantly upgraded version of Orbital ATK’s commercially developed Antares rocket has kicked into high gear and is on target for rebirth – as the clock ticks down towards its ‘Return to Flight’ by approximately mid-2016 from a launch pad at the Mid-Atlantic Regional Spaceport (MARS) in Virginia, company managers told Universe Today during a recent up close media visit to see the actual flight hardware.
