Boeing’s Orbital Flight Test 2 (OFT-2) mission to the Worldwide Area Station is poised to start at 6:54 p.m. EDT (2254 GMT) on Thursday (May 19) from Cape Canaveral Place Drive Station in Florida.
This second uncrewed take a look at mission of the company’s Starliner capsule serves as a crucial action in NASA’s certification of the spacecraft for human spaceflight, following the incomplete authentic OFT mission in December 2019 and valve troubles that delayed OFT-2’s liftoff from summertime 2021 until now.
OFT-2 will have additional than 500 lbs (225 kilograms) of cargo to the orbital laboratory, at minimum 440 lbs (200 kg) of which consists of foodstuff and materials for the station’s current crew. The remaining payloads have been contributed by Boeing and involve, among other flight memorabilia, keepsakes such as flags and pins commemorating the United States’ historically Black schools and universities (HBCUs).
“Closing illustration gaps in our firm and our sector is a precedence for Boeing, and inspiring numerous college students to go after professions in aerospace is an crucial component of that work,” Boeing President and CEO David Calhoun explained in a assertion past year.
Getting its second ride aboard Starliner will also be a flight take a look at dummy affectionately named Rosie the Rocketeer. Rosie rode aboard the initially OFT and furnished engineers facts about G-pressure exertion on the system all through start. For this flight, in accordance to a Boeing assertion, the identical sensors made use of for Rosie on OFT-1 will be made use of to measure the strain on the vehicle’s four seats immediately. (Rosie’s principal operate on OFT-2 will be to offer ballast, mission staff associates have mentioned.)
Robotic cargo launches to the house station are common, transpiring each and every couple months with a rotation of Russian Development vessels and two personal American automobiles — Northrop Grumman’s Cygnus spacecraft and SpaceX’s Dragon capsule. These freighters ferry big cargo loads to the ISS, and the reusable Dragon delivers equipment back again down as properly. (Development and Cygnus burn up in Earth’s ambiance when their time at the ISS is done.)
Speaking to the rewards of NASA’s professional crew program at a briefing in the runup to the initially planned OFT-2 launch attempt previous calendar year, NASA’s deputy chief scientist for the Intercontinental House Station Application, Jennifer Buchli, pointed out the rewards of becoming ready to transport a bigger variety of astronauts and science gear at a faster level, anything that Starliner could assist provide about:
“Having far more crew on orbit and much more cargo back again and forth from ISS implies we can do additional science,” Buchli stated. “We really do a vast range of experiments in anything from human analysis to fluid physics, to technological innovation demonstrations, daily life sciences, as properly as schooling.”
To date, NASA has finished about 3,000 experiments on the orbital lab, which has hosted rotating astronaut crews repeatedly considering that late 2000. These experiments, varying in their sizing and composition, make up a portion of the cargo routinely transported to, and in some cases back again from, the Intercontinental House Station.
Even so, it does not appear that Starliner will be transporting much meaningful science gear for the orbiting lab on the coming mission. According to NASA, OFT-2’s cargo includes “food and crew desire merchandise for the present-day expedition crewmembers on station and provisions, like clothes and sleeping baggage, for CFT astronauts.” (CFT stands for “Crew Flight Check,” the to start with Starliner astronaut mission, which Boeing and NASA prepare to start late this 12 months if all goes properly with OFT-2.)
For OFT-2, the science is principally the spacecraft alone (and, to a lesser extent, Rosie the Rocketeer). Screening no matter whether or not Starliner is ready for astronauts is very important before strapping them onboard for a crewed flight.
OFT-2 aims to reveal that Starliner can rendezvous and dock with the house station, a undertaking it unsuccessful to achieve during the primary OFT immediately after suffering a number of software glitches. To do this, the vehicle will use an instrument identified as the Vision-primarily based Electro-optical Sensor Tracking Assembly, or VESTA.
Talking on NASA’s “Houston, We Have a Podcast,” Amy Comeau, venture engineer for the Boeing Starliner main engineer’s workplace, highlighted VESTA as the “main focus” of OFT-2’s aim to dock with the station. She explained VESTA’s digital camera suite, which was designed to differentiate visible attributes of the room station in the very same way a human would:
“The technique utilizes visual cues on place station … such as the solar panels, stickers, the modules, and so on., and it also makes use of star tracker information so that it can interpret, [in] authentic time, the exact place of Starliner’s situation relative to the Worldwide Area Station’s placement. And so then this data is really fed into our flight computer systems that finally drive the spacecraft into the proper docking port.”
In a May possibly 11 press meeting next Starliner’s thriving flight readiness evaluate, NASA’s Deputy Main Flight Director Emily Nelson remarked that VESTA is “one of the most critical, and seriously type of the coolest, sensors they’ve received on [the] spacecraft.”
According to Nelson, once flight operators confirm VESTA is “seeing the room station appropriately and determining in which it should to go,” Starliner will get started a quantity of demonstration maneuvers. “The spacecraft will end to display that if we convey to it to cease, it will in reality stop. It’ll immediately retreat some, to exhibit that we have that retreat functionality. And then we’ll press into the remaining rendezvous and docking,” Nelson claimed.
Starliner will stay docked to the ISS for 5 to eight days ahead of parachuting back to Earth someplace in the western U.S., in accordance to NASA. When it returns, it will carry with it just about 600 lbs . (270 kg) of cargo, including 3 of the station’s dozen or so NORS (“Nitrogen Oxygen Recharge System”) tanks.
NORS tanks offer atmospheric gases to the house station. These tanks are frequently returned on cargo missions, and most not too long ago one accompanied the crew of the groundbreaking personal Ax-1 mission back to Earth in their SpaceX Dragon capsule past month. Nonetheless, OFT-2 will be the initially mission to return three NORS tanks at just one time, Joel Montalbano, supervisor for NASA’s ISS program, mentioned in the May well 11 briefing.
All through an OFT-2 overview press convention on May well 3, Montalbano summed up Starliner’s cargo, stating, “the bulk of the cargo heading up is going to be food items, and so about a tiny over 450, 460 kilos [204 to 209 kg] … And then, coming back, we’ll be bringing property some of the NORS tanks, the nitrogen oxygen recharge tanks that we have on board. They are employed, and so we’ll return them to the ground, refurb them and then fly these once again. And so that’s the large highlights. We’re also flying up some compact car or truck components, some EVA spacewalk source hardware as perfectly.”
The the vast majority of Boeing’s cargo will be returning to Earth with Starliner at the conclude of OFT-2 as effectively. In addition to the flags and pins symbolizing the legacy of HBCUs, other room-flown memorabilia on OFT-2 consist of Rosie the Riveter cash commemorating ladies in the aerospace business for the duration of Entire world War II, seeds from five distinctive species of trees to echo the “moon tree” hard work very first taken on by Apollo astronaut Stu Roosa in 1971, and also the unique firm ID card issued to Boeing founder Bill Boeing, which carries his signature.
