Fire on a spacecraft can be catastrophic. It can spread quickly in a confined space, and for trapped astronauts, there may be no escape. It’s fading in time now, but Apollo 1, which was to be the first crewed Apollo mission, never got off the ground because of a fire that killed the crew. There’ve been other dangerous spacecraft fires too, like the one onboard the Russian Mir space station in 1997.

In an effort to understand how fire behaves in spacecraft, NASA began its Saffire (Spacecraft Fire Safety Experiment) in 2016. Saffire was an eight-year, six-mission effort to study how fire behaves in space. The final Saffire test was completed on January 9th.

Northrup Grumman’s Cygnus cargo spacecraft conducted a successful reboost of the International Space Station over the past weekend, on Saturday, June 25, 2022. The Cygnus NG-17 “Piers Sellers” is the first US-based spacecraft to provide a substantial orbital adjustment to the ISS since the space shuttles retired in 2011. Russia’s Progress cargo spacecraft has been the primary source for station reboosts, attitude control, and debris avoidance maneuvers.

“This reboost of the ISS using Cygnus adds a critical capability to help maintain and support the space station,” said Steve Krein, vice president, civil and commercial space, tactical space systems, Northrop Grumman, in a press release. “It also demonstrates the enormous capability Cygnus offers the ISS and future space exploration efforts.”

On Tuesday, Sept. 29th, the Russian State Space Corporation (Roscosmos) announced that astronauts aboard the International Space Station (ISS) had found the source of a suspected leak. The crew of Expedition 63 – NASA astronaut and Commander Chris Cassidy and Russian cosmonauts Anatoly Ivanishin and Ivan Vagner – had been searching for this leak since August, and determined that it was “beyond expected levels.”

Roscosmos also said in a statement that “it was established that the spot is located in the Zvezda (star) service module, which contains scientific equipment.” They also emphasized that the leak “is not dangerous for the life and health of the ISS crew and does not prevent the ISS continuing manned flight.” Nevertheless, the amount of atmosphere lost may require additional oxygen to be pumped into the station.

NASA WALLOPS FLIGHT FACILITY, VA – Astronauts aboard the International Space Station are now busily unloading nearly four tons of science experiments, research gear, station equipment and crew supplies – following the spectacular launch of the Orbital ATK Antares rocket earlier this week on Sunday Nov. 12 from Virginia’s eastern shore that propelled the Cygnus cargo freighter to an on time arrival two days later on Tuesday Nov. 14.

The Orbital ATK Cygnus spacecraft was christened the S.S. Gene Cernan and named in honor of NASA’s Apollo 17 lunar landing commander; Gene Cernan.

Among the goodies delivered by the newly arrived S.S. Gene Cernan Cygnus OA-8 supply run to resident the crew of six astronauts and cosmonauts from the US, Russia and Italy are ice cream, pizza and presents for the holidays. They are enjoying the fruits of the earthy labor of thousands of space workers celebrating the mission’s success.

The S.S. Gene Cernan Cygnus spacecraft named in honor of the Apollo 17 lunar landing commander and launched by Orbital ATK from the eastern shore of Virgina at breakfast time Sunday, Nov. 12, arrived at the International Space Station early Tuesday morning, Nov 14, carrying over 3.7 tons of research equipment and supplies for the six person resident crew.

Soon thereafter at 5:04 a.m., Expedition 53 Flight Engineer Paolo Nespoli of ESA (European Space Agency) assisted by NASA astronaut Randy Bresnik successfully captured Orbital ATK’s Cygnus cargo freighter using the International Space Station’s 57.7-foot-long (17.6 meter-long) Canadarm2 robotic arm.

The station was orbiting 260 statute miles over the South Indian Ocean at the moment Nespoli grappled the S.S. Gene Cernan Cygnus spacecraft with the Canadian-built robotic arm.

Nespoli and Bresnik were working at a robotics work station inside the seven windowed domed Cupola module that offers astronauts the most expansive view outside to snare Cygnus with the robotic arms end effector.

The Cygnus cargo freighter – named after the last man to walk on the Moon – reached its preliminary orbit nine minutes after blasting off early Sunday atop the upgraded 230 version of the Orbital ATK Antares rocket from NASA’s Wallops Flight Facility in Virginia.

The flawless liftoff of the two stage Antares rocket took place shortly after sunrise Sunday at 7:19 a.m. EST, Nov. 12, rocket from Pad-0A at NASA’s Wallops Flight Facility in Virginia.

Sunday’s spectacular Antares launch delighted spectators – but came a day late due to a last moment scrub on the originally planned Veteran’s Day liftoff, Saturday, Nov. 11, when a completely reckless pilot flew below radar into restricted airspace just 5 miles away from the launch pad – forcing a sudden and unexpected halt to the countdown under absolutely perfect weather conditions.

After a carefully choreographed series of intricate thruster firings to raise its orbit over the next two days, the Cygnus spacecraft on the OA-8 resupply mission for NASA arrived in the vicinity of the orbiting research laboratory.

With Cygnus firmly in the grip of the robots hand, ground controllers at NASA’s Mission Control at the Johnson Space Center in Texas, maneuvered the arm towards the exterior hull and berth the cargo ship at the Earth-facing port of the stations Unity module.

1st stage capture was completed at 7:08 a. EST Nov 14.

After driving in the second stage gang of bolts, hard mate and capture were completed at 7:15 a.m.

The station was flying 252 miles over the North Pacific in orbital night at the time of berthing.

The Cygnus spacecraft dubbed OA-8 is Orbital ATK’s eighth contracted cargo resupply mission with NASA to the International Space Station under the unmanned Commercial Resupply Services (CRS) program to stock the station with supplies on a continuing and reliable basis.

NASA TV provided live coverage of the rendezvous and grappling.

Including Cygnus there are now five visiting vehicle spaceships parked at the space station including also the Russian Progress 67 and 68 resupply ships and the Russian Soyuz MS-05 and MS-06 crew ships.

Cygnus will remain at the space station until Dec. 4, when the spacecraft will depart the station and deploy several CubeSats before its fiery re-entry into Earth’s atmosphere as it disposes of several tons of trash.

On this flight, the Cygnus OA-8 spacecraft is jam packed with its heaviest cargo load to date!

Altogether over 7,400 pounds of science and research, crew supplies and vehicle hardware launched to the orbital laboratory and its crew of six for investigations that will occur during Expeditions 53 and 54.

NASA WALLOPS FLIGHT FACILITY, VA – The Orbital ATK Antares rocket is all set for a breakfast time blastoff from the commonwealth of Virginia to the International Space Station for NASA with a Cygnus cargo freighter named in honor of Gene Cernan, the last man to walk on the Moon.

The Antares launch is targeted for 7:37 a.m. EST on Saturday, Nov. 11, 2017 carrying the S.S. Gene Cernan resupply vessel that’s loaded with nearly four tons of science and supplies for the six person crew serving on the station.

Antares liftoff with the Cygnus spaceship also known as OA-8 will take place from launch Pad-0A at NASA’s Wallops Flight Facility located along the eastern shore of Virginia.

The rocket was integrated with the Cygnus OA-8 supply ship this week and rolled out to the launch pad starting around 1 a.m. EST this morning Thursday, Nov. 9.

The Cygnus OA-8 spacecraft is Orbital ATK’s eighth contracted cargo resupply mission with NASA to the International Space Station under the unmanned Commercial Resupply Services (CRS) program to stock the station with supplies on a continuing basis.

The upgraded Antares rocket was erected into the vertical position and is now poised for liftoff early Saturday morning.

Tens of millions of spectators could potentially witness the launch with their own eyeballs since NASA’s Wallops Flight Facility is located within a short driving distance of the most heavily populated area of the United States along the eastern seaboard.

Since Saturdays weather forecast is quite favorable at this time this could be your chance to watch an exciting launch on a critical mission for NASA with your family or friends.

See detailed visibility map below.

But be aware that temperatures will be rather chilly, setting record or near record lows in the 20s throughout the Northeast and Atlantic coast states.

If you are wondering whether to watch, consider that Antares launches are infrequent.

The last Antares launch from Wallops took place a year ago on 23 October 2016 for the OA-5 cargo resupply mission to the ISS for NASA.

If you can’t watch the launch in person, you can always follow along via NASA’s live coverage.

Live launch coverage will begin at 7 a.m. Saturday on NASA Television and the agency’s website: www.nasa.gov

The launch window opens at 7:37 a.m. EST.

The windows runs for five minutes extending to 7:42 a.m. EST.

The S.S. Gene Cernan manifest includes equipment and samples for dozens of scientific investigations including those that will study communication and navigation, microbiology, animal biology and plant biology. The ISS science program supports over 250 ongoing research investigations.

Among the science: “Cygnus will carry several CubeSats that will conduct a variety of missions, from technology demonstrations of laser communication and increased data downlink rates to an investigation to study spaceflight effects on bacterial antibiotic resistance. Other experiments will advance biological monitoring aboard the station and look at various elements of plant growth in microgravity that may help inform plant cultivation strategies for future long-term space missions. The spacecraft will also transport a virtual reality camera to record a National Geographic educational special on Earth as a natural life-support system.”

“Orbital ATK is proud to name the OA-8 Cygnus Cargo Delivery Spacecraft after former astronaut Eugene “Gene” Cernan,” said Orbital ATK.

“As the last human to step foot on the moon, Cernan set records for both lunar surface extravehicular activities and longest time in lunar orbit, paving the way for future human space exploration. He died in January 2017.”

The last Cygnus was named the S.S. John Glenn, first American to orbit Earth, and launched atop a ULA Atlas V in March 2017.

After a two day orbital chase Cygnus will reach the stations vicinity on Monday, Nov. 13.

“Expedition 53 Flight Engineers Paolo Nespoli of ESA (European Space Agency) and Randy Bresnik of NASA will use the space station’s robotic arm to capture Cygnus at about 5:40 a.m. NASA TV coverage of rendezvous and capture will begin at 4:15 a.m.,” said NASA.

“After Canadarm2 captures Cygnus, ground commands will be sent to guide the station’s robotic arm as it rotates and attaches the spacecraft to the bottom of the station’s Unity module. Coverage of installation will begin at 7 a.m.”

“Cygnus will remain at the space station until Dec. 4, when the spacecraft will depart the station and deploy several CubeSats before its fiery reentry into Earth’s atmosphere as it disposes of several tons of trash.”

Under the Commercial Resupply Services (CRS) contract with NASA, Orbital ATK will deliver approximately 28,700 kilograms of cargo to the space station. OA-8 is the eighth of these missions.

Aerospace giant Northrop Grumman will acquire Orbital ATK for approximately $9.2 billion, in a deal the companies announced Monday and they say will “expand capability” is largely “complementary” and involves “little overlap.”

Orbital ATK specializes in a wide variety of launch vehicles, satellites, missiles and munitions that Northrop believes will significantly enhance capabilities it lacks while offering Orbital significantly more technical and financial resources to grow sales and business opportunities.

Under the terms of the huge deal West Falls Church, Virginia based Northrop will dole out approximately $7.8 billion in cash to buy Dulles, Virginia based Orbital ATK and assume $1.4 billion in net debt. Orbital ATK shareholders will receive all-cash consideration of $134.50 per share, which is about a 20% premium above the stock’s price of $110 per share at the close of trading Friday, Sept. 15.

Rumors of the deal first appeared on Sunday.

The final purchase is expected to take place around mid-2018, subject to approval by government regulators and Orbital ATK shareholders.

The Boards of Directors of both companies have already given unanimous approval to the mega buyout.

“Our two companies represent a very complementary fit,” Wes Bush, chief executive officer and president of Northrop Grumman said in a conference call on Monday, Sept. 18.

“We have very little overlap, and we fully expect our combined portfolios of leading technologies, along with our aligned and innovation-focused cultures, to yield significant value creation through revenue, cost and operational synergies, accelerating our profitable growth trajectory.”

Northrop indicated that Orbital ATK will operate as a separate fourth unit – at least initially – and that Orbital programs will benefit from the increased financial resources available from Northrup.

“Upon completion of the acquisition, Northrop Grumman plans to establish Orbital ATK as a new, fourth business sector to ensure a strong focus on operating performance and a smooth transition into Northrop Grumman.”

For his part Orbital ATK CEO David Thompson was very pleased with the buyout and future opportunities.

“The agreement reflects the tremendous value that Orbital ATK has created for our customers, our shareholders and our employees,” David Thompson, Orbital ATK president and chief executive officer said at the conference call.

“The combination will allow our team as a new business sector within Northrop Grumman to maintain strong operational performance on existing customer programs and to pursue new opportunities that require greater technical and financial resources than we currently possess.”

“Our collective customers should benefit from the expanded capabilities for innovation, increased speed of delivery and improved affordability of production resulting from the combination.”

“The combination of our companies and human capital will also significantly benefit our customers,” Bush elaborated. “Together, we can offer our customers enhanced mission capabilities and more competitive offerings in areas such as space, missiles and strategic deterrents.

“Our shareholders can expect revenue synergies from these new business opportunities.”

Northrop Grumman sales for 2017 amount to about $25 billion vs. about $4.5 billion for Orbital ATK
Orbital ATK itself is the product of a very recent merger in 2015 of Orbital Sciences and ATK.

The company employs over 13,000 people including over 4,200 scientists and engineers. It holds a heft backlog of contracts worth more than $15 billion.

Northrop Grumman employs over 68,000 people and is the fifth largest defense contractor.

“The agreement will also provide expanded career options for our employees as part of a larger, more diverse aerospace and defense company,” said Thompson.

It will also benefit stockholders.

“The transaction represents a truly compelling financial proposition for our shareholders, valuing the enterprise at about $9.2 billion and providing our investors with more than 120% total return over the 3-year period from the completion of the Orbital ATK merger in early 2015 to the expected closing in the first half of 2018.”

Orbital ATK launchers run the gamut from small to medium to large.

The rockets include the massive solid rocket boosters for NASA’s Space Launch System (SLS) heavy lift rocket under development, the Antares liquid fueled booster used to launch Cygnus cargo freighters to the International Space Station for NASA, the Minotaur family of medium class solid rocket launchers, as well as sounding rockets for a variety of low weight science missions.

The most recent Orbital ATK launch took place on Aug. 26 when a Minotaur 4 rocket (a retired Peacekeeper ICBM) lifted off from Cape Canaveral with a USAF surveillance satellite.

Orbital ATK also has a thriving satellite manufacturing business building NASA science, commercial, government and military satellites.

Northrop Grumman is the prime contractor for NASA’s James Webb Space Telescope and designed the optics and spacecraft bus under contract for NASA’s Goddard Space Flight Center in Greenbelt, Maryland.

The first two missions of the unmanned Dream Chaser mini-shuttle carrying critical cargo to the International Space Station (ISS) for NASA will fly on the most powerful version of the Atlas V rocket and start as soon as 2020, announced Sierra Nevada Corporation (SNC) and United Launch Alliance (ULA).

“We have selected United Launch Alliance’s Atlas V rocket to launch our first two Dream Chaser® spacecraft cargo missions,” said SNC of Sparks, Nevada.

Dream Chaser will launch atop the commercial Atlas V in its most powerful configuration, dubbed Atlas V 552, with five strap on solid rocket motors and a dual engine Centaur upper stage while protectively tucked inside a five meter diameter payload fairing – with wings folded.

Blast off of Dream Chaser loaded with over 5500 kilograms of cargo mass for the space station crews will take place from ULA’s seaside Space Launch Complex-41 on Cape Canaveral Air Force Station in Florida.

The unique lifting body design enables runway landings for Dream Chaser, similar to the NASA’s Space Shuttle at the Shuttle Landing Facility runway at NASA’s Kennedy Space Center in Florida.

The ULA Atlas V enjoys a 100% success rate. It has also been chosen by Boeing to ferry crews on piloted missions of their CST-100 Starliner astronaut space taxi to the ISS and back. The Centaur upper stage will be equipped with two RL-10 engines for both Dream Chaser and Starliner flights.

“SNC recognizes the proven reliability of the Atlas V rocket and its availability and schedule performance makes it the right choice for the first two flights of the Dream Chaser,” said Mark Sirangelo, corporate vice president of SNC’s Space Systems business area, in a statement.

“Humbled and honored by your trust in us,” tweeted ULA CEO Tory Bruno following the announcement.

Liftoff of the maiden pair of Dream Chaser cargo missions to the ISS are expected in 2020 and 2021 under the Commercial Resupply Services 2 (CRS2) contract with NASA.

“ULA is pleased to partner with Sierra Nevada Corporation to launch its Dream Chaser cargo system to the International Space Station in less than three years,” said Gary Wentz, ULA vice president of Human and Commercial Systems.

“We recognize the importance of on time and reliable transportation of crew and cargo to Station and are honored the Atlas V was selected to continue to launch cargo resupply missions for NASA.”

By utilizing the most powerful variant of ULA’s Atlas V, Dream Chaser will be capable of transporting over 5,500 kilograms (12,000 pounds) of pressurized and unpressurized cargo mass – including science experiments, research gear, spare part, crew supplies, food, water, clothing and more per ISS mission.

“In addition, a significant amount of cargo, almost 2,000 kilograms is directly returned from the ISS to a gentle runway landing at a pinpoint location,” according to SNC.

“Dream Chaser’s all non-toxic systems design allows personnel to simply walk up to the vehicle after landing, providing immediate access to time-critical science as soon as the wheels stop.”

“ULA is an important player in the market and we appreciate their history and continued contributions to space flights and are pleased to support the aerospace community in Colorado and Alabama,” added Sirangelo.

Under the NASA CRS-2 contract awarded in 2016, Dream Chaser becomes the third ISS resupply provider, joining the current ISS commercial cargo vehicle providers, namely the Cygnus from Orbital ATK of Dulles, Virginia and the cargo Dragon from SpaceX of Hawthorne, California.

NASA decided to plus up the number of ISS commercial cargo providers from two to three for the critical task of ensuring the regular delivery of critical science, crew supplies, provisions, spare parts and assorted gear to the multinational crews living and working aboard the massive orbiting outpost.

NASA’s CRS-2 contracts run from 2019 through 2024 and specify six cargo missions for each of the three commercial providers.

By adding a new third provider, NASA simultaneously gains the benefit of additional capability and flexibility and also spreads out the risk.

Both SpaceX and Orbital ATK suffered catastrophic launch failures during ISS resupply missions, in June 2015 and October 2014 respectively, from which both firms have recovered.

Orbital ATK and SpaceX both successfully launched ISS cargo missions this year. Indeed a trio of Orbital ATK Cygnus spacecraft have already launched on the Atlas V, including the OA-7 resupply mission in April 2017.

SpaceX has already launched a pair of resupply missions this year on the CRS-10 and CRS-11 flights in February and June 2017.

Unlike the Cygnus which burns up on reentry and Dragon which lands via parachutes, the reusable Dream Chaser is capable of low-g reentry and runway landings. This is very beneficial for sensitive scientific experiments and allows much quicker access by researchers to time critical cargo.

Dream Chaser has been under development for more than 10 years. It was originally developed as a manned vehicle and a contender for NASA’s commercial crew vehicles. When SNC lost the bid to Boeing and SpaceX in 2014, the company opted to develop this unmanned variant instead.

A full scale test version of the original Dream Chaser is currently undergoing ground tests at NASA’s Armstrong Flight Research Center in California. Approach and landing tests are planned for this fall.

Other current cargo providers to the ISS include the Russian Progress and Japanese HTV vessels.

KENNEDY SPACE CENTER, FL – The SS John Glenn commercial Cygnus resupply vessel arrived at the International Space Station early this morning, April 22, 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, the commercial Cygnus cargo ship 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 stations Canardarm2.

Working at robotic work consoles inside the domed Cupola module, Pesquet and Whitson deftly maneuvered the space station’s 57.7-foot (17.6-meter) Canadian-built Canadarm2 robotic arm to reach out and flawlessly snare the Cygnus CRS-7 spacecraft at 6:05 a.m. EST at the short and tiny grappling pin located at the base of the vessel.

Cygnus and the station were soaring some 250 miles (400 km) over Germany as they were joined at Canada’s high tech arm in a perfect demonstration of the peaceful scientific purpose of the massive laboratory complex.

The private supply ship was moved and bolted into place a few hours later at 8:19 a.m. EDT to physically berth and join the station at the Unity module.

Thus begins a three month long sentimental journey ‘bridging history’ to the dawn of America’s human spaceflight with the cylindrically shaped ship named in tribute to John Glenn – the first American to orbit Earth way back in 1962.

The SS John Glenn is a private Cygnus spacecraft manufactured by Orbital ATK under the commercial resupply services (CRS) contact with NASA whose purpose is to deliver many thousands of pounds of cargo and research supplies to the space station to enable the scientific research for which it was built.

Cygnus arrived at the station via a carefully choreographed series on thruster maneuvers after almost four days in orbit following liftoff earlier this week.

The SS John Glenn blasted to orbit on time at 11:11 a.m. EDT Tuesday, April 18 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 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.

The entire rendezvous and grappling sequence was broadcast live on NASA TV starting at 4:30 a.m. Saturday: http://nasa.gov/nasatv

“Over the pin. Trigger initiated and snares closed,” radioed Pesquat in the final moments of approach as he carefully and ever so slowly moved the arm towards Cygnus this morning.

“Capture confirmed right on time at 6:05 a.m,” replied Houston Mission Control.

“We have a good capture, and are go for safing,” reported Station Commander Whitson.

“The crew of Expedition 51 would like to congratulate all the teams at NASA, Orbital ATK and the contractors for a flawless cargo-delivery mission,” Pesquat elaborated. “We are very proud to welcome onboard the S.S. John Glenn.”

“The more than three tons of pressurized cargo in the Cygnus spacecraft will be put to good use to continue our mission of research, exploration and discovery. Achievements like this, fruit of the hard work by space agencies and private companies and the international cooperation across the world, are what truly makes the ISS such a special endeavor at the service of all mankind.”

“Station, Houston, well said,” replied Mission Control.

After the astronauts finished their work in orbit, mission controllers in Houston took over and commanded the arm to move Cygnus to the Earth facing port on Node 1 where it was remotely bolted in place with 16 hooks and latches and hard mated to the Unity module.

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.

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.

Science plays a big role in this mission 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.
