The first few flights of Boeing\u2019s CST-100 Starliner commercial crew capsule will likely land on expansive desert plains in New Mexico or Utah, according to a former astronaut charged with developing the spacecraft\u2019s operations scheme.<\/p>\n

Boeing is still finalizing a list of five candidate landing sites in the Western United States, but the U.S. Army\u2019s White Sands Missile Range in New Mexico and the Army\u2019s Dugway Proving Ground in Utah will initially be the prime return locations, said Chris Ferguson, deputy manager of the CST-100 Starliner program.<\/p>\n

The capsules will parachute to airbag-cushioned landings after each mission, beginning with the CST-100\u2019s first test flights in 2017. Boeing is developing the program under a $4.2 billion contract with NASA, which also has an agreement with SpaceX to give the agency two independent vehicles to ferry astronauts between Earth and the International Space Station.<\/p>\n

\u201cWe don\u2019t enjoy the tremendous cross range with a capsule vehicle that we had with the space shuttle,\u201d said Ferguson, a two-time shuttle commander who flew on the final shuttle flight in 2011. \u201cThat\u2019s why we need a few more sites to give us the landing opportunities over the course of the year that we need. With five sites, we can get about 450 opportunities to land every year.\u201d<\/p>\n

That\u2019s assuming no bad weather and stable ground for the capsule\u2019s airbag landing. Ferguson said five landing sites gives Boeing enough options to ensure a landing the same day the spacecraft undocks from the space station, even accounting for poor conditions.<\/p>\n

All of the candidates are in the Western United States, allowing the capsule to drop its disposable service module for a destructive re-entry over the Pacific Ocean, Ferguson said.<\/p>\n

\u201cSome of the (landing sites) are very familiar to you \u2014 Edwards Air Force Base and White Sands,\u201d Ferguson said. \u201cDugway Proving Ground is a new one \u2026 but they have a lot of features that we like. There are others that are candidates. I don\u2019t want to mention them just yet until we can really solidify the details with them, but suffice it to say they\u2019re in the western part of the United States, and we look for areas that no one else is. You can extrapolate where that is. The Southwest is a good place to land.\u201d<\/p>\n

The space shuttle had three standard landing sites: Kennedy\u2019s Space Center\u2019s Shuttle Landing Facility, a concrete landing strip at Edwards Air Force Base, and a gypsum runway at White Sands.<\/p>\n

Boeing officials say the CST-100 Starliner\u2019s first unpiloted demonstration flight is scheduled for May 2017, when the capsule will fly to the International Space Station, dock with the complex to deliver cargo, then return to Earth.<\/p>\n

The demo flight is followed by a pad abort test at White Sands in August 2017, a CST-100 demo mission with astronauts in September 2017, and final certification of the human-rated craft by NASA before operational crew rotation missions begin in December 2017.<\/p>\n

Boeing wants to narrow down the roster of landing sites for the CST-100 Starliner\u2019s first two test flights in 2017.<\/p>\n

\u201cWe\u2019re focusing on White Sands and Dugway as our target sites for those flights,\u201d Ferguson said. He declined to rank which location would be the prime landing site, saying that decision could be made much closer to the mission.<\/p>\n

The third space shuttle mission landed at White Sands in 1982, and two NASA robotic probes \u2014 Genesis and Stardust \u2014 returned to Earth at Dugway with solar wind and cometary samples.<\/p>\n

Each CST-100 mission to orbit will launch from Cape Canaveral aboard United Launch Alliance Atlas 5 rockets.<\/p>\n

Boeing officials are working on mission control guidelines for CST-100 flights as technicians in Florida assemble the capsule\u2019s first test article.<\/p>\n

\u201cAfter we get through integrated testing and production, we have to go into operations,\u201d Ferguson said. \u201cBoeing is great at building products, and then we typically sell them to somebody else who operates them.\u201d<\/p>\n

That is not the case for the CST-100 program.<\/p>\n

Boeing is the capsule\u2019s owner and operator, but the aerospace contractor is delegating front line control responsibility to NASA\u2019s mission control experts at the Johnson Space Center in Houston. NASA\u2019s crew trainers will also get CST-100 passengers ready for flight.<\/p>\n

\u201cIt will have a different look to it, but a lot of those same faces will be part of the control team that worked the last space shuttle flight,\u201d Ferguson said.<\/p>\n

John Mulholland, Boeing\u2019s CST-100 program manager, said the company selected NASA\u2019s mission control team because \u201cthey are the only entity that has done the plan, train and fly portion of a domestic human space mission.\u201d<\/p>\n

The first launch day simulation with Boeing, NASA and ULA teams is scheduled for January, according to Ferguson. ULA\u2019s Atlas 5 rocket, like other launchers, cannot be controlled in flight, but the booster will carry a computer designed to detect failures and trigger an abort, separating the crew capsule before an explosion.<\/p>\n

\u201cThe spacecraft and the astronauts on-board will always be talking to the control center in Houston,\u201d Ferguson said. \u201cThe reason being they have that familiarity element with the CAPCOM (spacecraft communicator), and understanding that we\u2019re going to be working with Houston for the entire mission, not just for that short period of ascent. We thought it was very advantageous to build that relationship and work with one control entity.\u201d<\/p>\n

Meanwhile, spacecraft construction at the Starliner factory at NASA\u2019s Kennedy Space Center is ramping up. The program will eventually employ 550 people on Florida\u2019s Space Coast as the CST-100 moves into full operations.<\/p>\n

\u201cThe team is doing extremely well,\u201d Mulholland said. \u201cThe performance to plan has been very strong. If you look at the performance of the team over the past year, we\u2019ve achieved the milestones in this calendar year that we had planned.\u201d<\/p>\n

Pieces of the CST-100 Starliner\u2019s structural test article, including forward and aft domes, a tunnel and a hatch, are inside the KSC assembly plant, which was once a space shuttle hangar.<\/p>\n

\u201cWe\u2019re really coming into a different phase right now as the design activity is rolling to completion,\u201d Mulholland said. \u201cReally, the focus now is turning to manufacturing, and then integrated testing \u2026 We\u2019ve got a number of our components that have already either finished qualification testing, or are starting, or are in some phase of qualification testing.\u201d<\/p>\n

Boeing is taking a different approach to development of its human-rated spacecraft than SpaceX, which has already completed a pad abort test and plans an in-flight abort demo in late 2016. SpaceX is testing as it goes, while Boeing is doing more design work up front.<\/p>\n

\u201cA lot of focus is on ensuring, at this phase, that we\u2019ve got full rigor in all our processes and all of our designs, really trying to buy down the risk that something could come up downstream to perturbate either our design or our schedule,\u201d Mulholland said.<\/p>\n

Boeing plans no such in-flight escape test, and Mulholland said it can prove out the CST-100 abort system through wind tunnel analyses.<\/p>\n

\u201cThat\u2019s our philosophy \u2014 to make sure we don\u2019t run a test just to go run a test,\u201d Mulholland said. \u201cWe make sure we fully understand all the requirements that we need to certify to, and we pick the best approach.\u201d<\/p>\n

Mulholland said the sequence of test flights in 2017 is tight, but Boeing\u2019s schedule has margin to achieve the start of operational missions by the end of that year. Managers decided to move the pad abort test from early 2017 to August, a change that Mulholland said created more margin in the schedule leading to the first crew flight.<\/p>\n

Boeing is building at least three flight-ready CST-100 crew modules, and each will be certified for up to 10 missions. Every flight will require a new service module. The company could order more vehicles if Boeing wins a contract to resupply the space station with cargo, an award NASA expects to announce November.<\/p>\n

Pieces of the first space-rated Starliner arrive at KSC at the end of the year, and engineers will put together a qualification unit after shipping a stripped-down structural test article to a Boeing facility in Huntington Beach, California, for loads testing.<\/p>\n

The qualification article will be outfitted for the pad abort once its ground testing is complete, and Boeing will fly newly-built capsules for the uncrewed and crewed demonstrations to the space station.<\/p>\n

\u201cWe made the decision earlier in the year to jiggle that flow up a little bit, and do the pad abort test on the qualification test vehicle,\u201d Mulholland said. \u201cWhat that allowed us to do was to put an additional five months of margin in our build sequence, and use new-build crew modules for the uncrewed flight and the crewed flight test.\u201d<\/p>\n

Designers have also added body-mounted solar cells to the aft end of the CST-100 service module to give the spacecraft more power, Mulholland said. The extra power ensures the capsule meets its requirements set by Boeing and NASA.<\/p>\n

\u201cWe have to launch and dock within 24 hours, be able to wave off that docking and hold for 24 hours, then stay docked for six months, undock, have a waved off landing for 24 hours, and then land,\u201d Ferguson said. \u201cWe can support that with our current battery and solar array structure.\u201d<\/p>\n

Ferguson said Boeing and NASA should announce the two-person crew for the CST-100\u2019s first piloted test mission next year. The duo will include a Boeing pilot and a NASA astronaut. Many observers believe Ferguson, a veteran of three space shuttle missions, could be Boeing\u2019s test pilot.<\/p>\n

NASA has already announced a group of four astronauts to start training on CST-100 and Crew Dragon systems to fly on commercial spaceships, but no specific crews have been named.<\/p>\n

Boeing and SpaceX crewed flights by the end of 2017 depend on Congress appropriating $1.2 billion for the commercial crew program, in line with NASA\u2019s request, according to agency officials.<\/p>\n
