Antares Rocket Rolls to Pad as Drenching Rain Delays Cargo Launch to ISS to May 21

WALLOPS FLIGHT FACILITY, VA - Orbital ATK’s Antares rocket loaded with the Cygnus cargo spacecraft destined for the International Space Station (ISS) has rolled out to the launch pad at NASA’s Wallops Flight Facility on Virginia’s Eastern shore - even as drenching days of rain forced a days delay to the nighttime liftoff now rescheduled to Monday, May 21.

Liftoff of the two stage Antares rocket carrying the Cygnus resupply spaceship is now slated for a 5-minute window that opens at 4:39 a.m. EDT May 21 from Pad 0A of Virginia Space’s Mid-Atlantic Regional Spaceport at Wallops.

Check out our exclusive SpaceUpClose photos of the Antares rocket resting horizontally at pad OA this afternoon May 18 during a brief break in the rain and thick ground level fog.

The rocket measures 42.4 meters in height and 3.9 meters in diameter.  The Cygnus has a pressurized volume of 27 cubic meters and is 6.39 m in height. It is loaded with 800 kg (1764 lb) of propellants.

The much anticipated Antares launch had been set to take off at 5:04 a.m. EDT May 20, but was officially postponed earlier today because of several days of nearly continuous terrible rain squalls inundating much of the US East Coast from New York to Florida.

Weather forecasters say there is an 80-percent probability of acceptable weather for launch of Antares with Cygnus in the wee hours of Monday morning.

“Orbital ATK in conjunction with NASA, has moved the Antares and Cygnus launch to NET Monday, May 21st at 4:39 a.m. EDT to support further pre-launch inspections and more favorable weather conditions, Orbital SATK said in a statement. “Monday shows an 80% probability of acceptable weather for launch.”


The rocket was rolled out of the Horizontal Integration Facility (HIF) late Thursday, May 17 for the 1 mile trip from the rocket assembly facility to the OA launch pad at NASA Wallops.




The targeted launch date was adjusted from May 20 to May 21 after the rocket rollout was completed.

The Cygnus vessel is jam packed with over 3.5 tons of science and supplies bound for the six person multinational crew living and working aboard the million pound orbiting outpost.

The mission, alternatively named CRS-9 or OA-9 , is Orbital ATK’s ninth contracted cargo delivery flight to the International Space Station for NASA.

On board Cygnus are 7,400 pounds (3,350 kg) of cargo including science experiments, research gear, food, water, spare parts, crew supplies and vehicle hardware to support the Expedition 55 and 56 crews.

Cygnus will deliver vital equipment, supplies and scientific equipment to the space station as part of Orbital ATK’s Commercial Resupply Services (CRS) contract with NASA.


The prior Cygnus cargo freighter was successfully launched by an Antares 230 vehicle from Wallops on Nov. 11, 2017 on the OA-8 resupply mission for NASA .


Among the research experiments on OA-9 are; the space Sextant Navigation investigation testing use of a hand-held sextant by astronauts for emergency navigation on missions in deep space as humans begin to travel farther from Earth; the Cold Atom Lab (CAL) is a new facility that will create a spot ten billion times colder than the vacuum of space, and could help us answer some of the biggest questions in physics; and Biomolecule Extraction and Sequencing Technology (BEST), an investigation to identify unknown microbial organisms on the space station and understand how humans, plants and microbes adapt to living on the station.


After it departs, Cygnus will also deploy a number of cubesats from a Nanoracks supplied deployer.

The Cygnus is named the SS J.R. Thompson - after J.R. Thompson, a distinguished leader in the aerospace industry and a member of the Orbital ATK family.


“Thompson was a distinguished leader in the aerospace industry who helped shape the strategy and directed the operations of Orbital ATK's predecessor company, Orbital Sciences Corporation, for nearly 25 years. Before joining Orbital, Thompson was NASA's Deputy Administrator from 1989 to 1991,” said Orbital ATK in a statement.  
The cylindrically shaped spaceship will reach orbit some eight minutes after liftoff and begin an orbital chase

Cygnus will arrive at the ISS on May 24, three days after launch and a carefully choreographed series of thruster firings.  

“Three NASA astronauts aboard the station will manage the spacecraft’s arrival,” said NASA. “Expedition 55 Flight Engineer Scott Tingle will grapple the spacecraft, backed by Ricky Arnold, and Drew Feustel will monitor Cygnus systems during its approach.”

“They will use the space station’s robotic Canadarm2 to grab the spacecraft and ground controllers will command the robotic arm to rotate and install Cygnus onto the station’s Unity module.”

NASA will televise prelaunch science and mission briefings over the weekend on Saturday and Sunday.



The public is invited to watch the launch for free from the NASA Wallops Visitor Center which opens at 1 AM on May 21.

“Additional locations for catching the launch are Robert Reed Park on Chincoteague Island or Beach Road spanning the area between Chincoteague and Assateague Islands. Assateague Island National Seashore/Chincoteague National Wildlife Refuge in Virginia will not be open for viewing the launch,” says NASA.


The launch could be visible to tens of millions of spectators all along the US East Cost depending on clear weather conditions.
