Bigelow Expands Our Horizons

On the second try, Bigelow Aerospace and NASA successfully expanded and pressurized a new prototype habitat module.

The Bigelow Expandable Activity Module (BEAM) was attached April 16 to the International Space Station. Expansion had to wait until crew time was available in late May.

The process began on May 26, but was suspended after expansion failed despite increased pressurization.

BEAM had been compacted about seven months longer than intended, so team members theorized that allowing the fabric to “relax” might do the trick. The bladders between the fabric layers were depressurized. Because BEAM is in the vacuum of space, it retained its shape.

Proceeding slowly on May 28, astronaut Jeff Williams added a second or two of pressure when directed by ISS Mission Control. As BEAM continued to expand, longer and frequent bursts of air were permitted.

According to a NASA press release:

The module measured just over 7 feet long and just under 7.75 feet in diameter in its packed configuration. BEAM now measures more than 13 feet long and about 10.5 feet in diameter to create 565 cubic feet of habitable volume. It weighs approximately 3,000 pounds.

During the next week, leak checks will be performed on BEAM to ensure its structural integrity. Hatch opening and NASA astronaut Jeff Williams’ first entrance into BEAM will take place about a week after leak checks are complete.

SpaceX launched a telecommunications satellite yesterday for its customer Thaicom, but once again Elon Musk managed to break the Internet with video footage of the Falcon 9 landing.

The camera was mounted looking down the fuselage as the F9 re-entered the atmosphere. The camera angle is evocative of this iconic scene from Doctor Strangelove.

This was the third landing of a first stage booster on the barge Autonomous Spaceport Drone Ship, Of Course I Still Love You. In December 2015, SpaceX landed a Falcon 9 on the former Launch Complex 13 at Cape Canaveral Air Force Station.

Bigelow Under Pressure

Click the arrow to listen to the May 27, 2016 teleconference with NASA and Bigelow Aerospace representatives.

Perhaps we had inflated expectations, hoping that the Bigelow BEAM would expand nominally as demonstrated in artists' concepts.

Pressurization halted yesterday after the prototype habitat stopped expanding. NASA and Bigelow managers chose to pause to examine data returned from the Bigelow Expandable Activity Module berthed at the International Space Station's Node 3.

During the night, the fabrics relaxed enough that BEAM continued to slowly expand on its own.

Today's teleconference participants said BEAM has been depressurized for now, reducing the air in the bladders between the layers of fabric. Because it's in a vacuum, BEAM is retaining its shape even though the bladders are nearly empty.

BEAM was delivered to NASA in March 2015. Slated for launch on the SpaceX Dragon CRS-8 mission in September 2015, the launch was delayed seven months due to the loss of the SpaceX-7 mission in June 2015. The next flight had to wait until SpaceX solved the cause of the accident.

No one anticipated BEAM remaining tightly packaged for over a year.

But because this is a test, in a sense that's good because it allows NASA and Bigelow to test the prototype for behavior under such conditions.

Telecon participants stated that “friction force between the fabrics” is considered the likely cause for the habitat's failure to properly expand, but they remain fully confident that expansion will be achieved.

Another reason to proceed slowly is that Bigelow is collecting data on how the pressurization places stress loads on Node 3 and the station.

During an April 11, 2016 media event, Robert Bigelow and United Launch Alliance CEO Tory Bruno discussed their intent to pursue a deal to attach the larger next-generation Bigelow B-330 to ISS in the 2020s for commercial use. Studying how BEAM impacts the station structure collects data for that future enterprise.

NASA media representative Dan Huot said at the end of the telecon that tomorrow's attempt will be telecast live on NASA TV, but the time is to be determined.

If this attempt fails, further efforts will be delayed for about a week as ISS crew members have other activities scheduled, some of which involve the Canadarm. BEAM's expansion could cause vibrations that affect the arm's performance.

Mapping the Cape, Part 2

This 1958 image shows Highway A1A rerouted from the Cape to Highway 520 in Cocoa Beach. Click the image to view at a larger size. Image source: NASA.

When the military took over Cape Canaveral in the early 1950s, Florida's Highway A1A ran right through the heart of what would become the epicenter for the missile race between the United States and the Soviet Union.

Highway A1A used to run up the coastline to Daytona Beach. The old Highway A1A through the Cape today is known as General Samuel C. Phillips Parkway. The road continues north between the Atlantic Ocean and the active launch pads for United Launch Alliance and SpaceX. The old A1A continues north through Kennedy Space Center, known to many as “the Cape Road,” and into Canaveral National Seashore.

By 1958, Highway A1A had been redesignated to State Route 520 between Cocoa Beach and Merritt Island. At the western end, it connected to State Route 3, known today as Courtenay Parkway. Courtenay was a small town near what today is just south of the south gate of Kennedy Space Center. Before the arrival of KSC, parts of SR-3 were actually Tropical Trail, a two-lane north-south artery that parallels the Indian River.

If you drove north on SR-3, you'd pass through Courtenay and then through Orsino, another small town that would disappear once NASA bought up 144,000 acres on north Merritt Island to build Kennedy Space Center.

I've long been interested in locating any images of the towns and roads that existed when the government bought up KSC, so I visited the North Brevard Historical Society & Museum in Titusville.

Most of their collection reflects the lifestyles of those who lived in the region going back to the 1890s. A few artifacts are on file, which helped piece together the cartographical jigsaw puzzle.

In the museum's collection is a 1926 map of Brevard County by the Associated Map Co. of Miami, Florida. The map shows the major routes and small towns that dotted Cape Canaveral and Merritt Island at the time.

(Merritt Island is labelled as “Merritt's Island,” and Courtenay is spelled “Courteney.”)

In a December 2014 article, I wrote about how two dirt roads ran east from Highway A1A to the Cape Canaveral coastline. Look for the CANAVERAL town marker. The road paralleling the coastline was the Pier Road, so called because the paved road ended at the Canaveral Pier. The other road is Lighthouse Road; the map shows it ends just south of the LIGHT HOUSE. The road from the pier to the lighthouse was unpaved.

The road was still unpaved in 1950, when the first rockets were being launched from the tip of Cape just beyond the lighthouse. Those converted V-2 missiles were stored at Patrick Air Force Base to the south, then towed up Lighthouse Road to Pad 3 for launch.

This 1950 image taken from the lighthouse shows the road was still unpaved as of that date.

Highway A1A merged with Lighthouse Road near what then was known as DeSoto Beach. That's roughly north of today's Launch Complex 37, used by United Launch Alliance for the Delta IV booster. Early 1950s maps of the station show patrol roads at the north and south borders. North Patrol Road still exists today, running east-west between Launch Pads 34 and 37.

The arrival of so many rocket and missile programs in the 1950s began to erase decades of Cape history. Small towns such as DeSoto Beach were purchased by the government and bulldozed.

Lighthouse Road was partially closed circa 1956 for the Thor pads at Launch Complex 17. The remnants of Lighthouse Road are still visibile in this 1958 image; the old dirt road was still visible running through the complex to intersect with the Pier Road.

Further north on the old Highway A1A was Titusville Beach. That's roughly where Kennedy Space Center's launch pads 39A and 39B are located.

Much of that area was reworked in the early 1960s. NASA contractors dredged old swamp land and parts of the Banana Creek, using sediment and rocks and sand to fill the landscape.

A 1966 documentary called “The Big Challenge” about the construction of Kennedy Space Center, originally produced by NASA and the Army Corps of Engineers.

The Big Challenge is a 1966 film documenting the construction of KSC, including its launch pads. It shows the dredging and filling to construct the pads, the Vehicle Assembly Building, and the major causeways.

Hanging on the museum's wall is this undated image of Titusville Beach. The caption at the bottom reads:

Houses along Titusville Beach prior to NASA acquiring the land in the 1960s. Playalinda Beach is in the far distance. The cleared area to the left of State Road A1A was the site of Sunrise Beach, the only subdivision ever constructed in the beach area.

I have to wonder if that lone condo on the shoreline across from the “cleared area” might be the famous Astronaut Beach House. According to a 2005 NASA article, the condo was built as a model for the Neptune Beach subdivision. The location in the image is about the right place. The black-and-white colors appear similar.

After the old Highway A1A was rerouted off-base, travelers headed north on State Route 3 to reach Daytona Beach. But as NASA began buying up north Merritt Island in the early 1960s, Highway A1A once again was designated elsewhere.

The town of Orsino existed roughly where NASA Parkway and Kennedy Parkway intersect today. State Route 405 across the Indian River did not exist until 1965.

As seen in the 1926 map, travellers reaching Orsino from the south turned right on what was known as Orsino Road, then could turn left to proceed north. If they continued east, the road ended at the Banana River.

The above image is of a convenience store located roughly where today's NASA and Kennedy Parkways intersect. According to an undated Florida Today article by columnist Milt Salamon in the Museum's file, it was a combination “post office-store-gas station.”

The Orsino Baptist Church was located just south of the convenience store and a half-mile west of State Route 3. According to the Orsino Baptist Church web site, the original building was moved in its entirely about four miles south.

The church web site states:

The church was located in the community of Orsino approximately one-half mile west of S.R. #3 on what is now called the NASA Parkway. NASA took over the property where the church was located.

In 1963, the church was required to move from the small community of Orsino, named after the homesteader, Orsino Smith. The Chamber of Commerce was disbanded and the officers of the Chamber of Commerce voted to donate the money left in the treasury ($255.91) to the building fund for Orsino Baptist Church. The pastor at that time was Reverend J.L. Gaines. In July of 1963, the original building was moved to the current location at 4505 N. Courtenay Parkway in Merritt Island.

According to the Milt Salamon column, NASA paid to move the church building.

Where does Highway A1A run today?

According to Google Maps, it continues west on State Route 528, which loses the A1A designation at the Indian River west of Merritt Island. The A1A designation resumes in Volusia County at the north end of Canaveral National Seashore and the Mosquito Lagoon, south of New Smyrna Beach on a local road known as Atlantic Avenue.

Bigelow on Display

A display of the Bigelow Aerospace BEAM and B-330 habitats is now at the Kennedy Space Center Visitor Complex. It's on the third floor of the Space Shuttle Atlantis building, behind the orbiter.

Note that the crew vehicle docked at the B-330 is a SpaceX crew Dragon.

These are images I shot of the display. The images may be used elsewhere with credit to Click on the image to view at a larger size.
