Starliner Spacecraft's Landing on Sunday a Critical Moment for Boeing and NASA –,

Boeing’s firstStarliner spacecraftwill return to Earth Sunday (Dec.) to cap a rocky test flight that, despite some successes, left the capsule in the wrong orbitand unable to reach the International Space Station for NASA as planned.If all goes according to the revised plan, the uncrewed Starliner – which Boeing designed to eventually fly astronauts forNASA– will land at White Sands Space Harbor in New Mexico at 7: am EST ( (GMT), six days earlier than its original Dec. 50 target. The spacecraft will rely on a heat shield to withstand the searing heat of reentry, three parachutes to slow its descent back to Earth and airbags to cushion its landing. And all of that gear needs to work perfectly for a safe touchdown.“Tomorrow is a big day,” NASA Administrator Jim Bridenstine said of Starliner’s landing

A smooth, successful landing will be a redemption of sorts for Boeing’s Starliner, which was left in its unplanned orbit due to atiming error with the spacecraft’s mission clock

. The glitch meant Starliner, which launched early Friday (Dec., was unable to rendezvous with the space station to demonstrate its automated docking system , a vital capability for future astronaut missions.But just as vital is landing safely. And that’s what Boeing will attempt to show on Sunday.

“Entry, descent and landing is not for the faint of heart, and this vehicle has not entered, “said Jim Chilton, senior vice president of Boeing’s Space and Launch Division. “We have not gone from space to the atmosphere.”************************************************************ ********************************

Starliner’s return to Earth will occur in stages, each of which must go right for the spacecraft to land safely. First, Starliner will have to leave its current orbit, which is about (miles) (kilometers) above Earth.

To do that, Starliner’s service module will fire its thrusters in a so-called “deorbit burn” at 7: 23 am EST ( (GMT) that will last 57 seconds. That should slow the spacecraft to about times the speed of sound, Steve Stich, deputy manager of NASA’s Commercial Crew Program, said in the teleconference. Mach (is about) ********************************************************************************************************************, ****************************************************************************************** mph (22, (km / h).After the deorbit burn, the cylindrical service module should separate from the Starliner crew capsule and perform its own maneuver to fall safely out space and into the Pacific Ocean, Stich said.

The rest of the landing scenario relies on Starliner’s crew capsule, which will plunge through the atmosphere on a trajectory that flies over the Pacific Ocean and crosses Baja California and Mexico, and then just west of El Paso, Texas, to reach a landing zone at White Sands Space Harbor in New Mexico.

Earth’s atmosphere, its heat shield will heat up to 3, (degrees Fahrenheit) 1, 728 degrees Celsius), according to a Boeing mission description. The spacecraft will then jettison that heat shield and prepare to deploy its parachutes.

By the time we get to (*******************************************************************************************************************, (feet [9,100 meters], we’ll deploy parachutes ; the vehicle will be going less than the speed of sound, less than Mach 1, “Stich said.Starliner is equipped with three main parachutes to slow its descent back to Earth. During a pad abort test in November,only two of those parachutes deployed during a Starliner landing, a glitch Boeing pegged to a misaligned pin in the parachute rigging system.

Chilton said both Boeing and NASA have checked and double-checked that the pins in the current Starliner’s parachutes were installed correctly.

We did have a NASA team go in and look at all the closeout photos, “Stitch added. “The parachutes on this spacecraft were rigged correctly.”************************************ (Starliner’s big test

At 3, (feet) m), air bags should inflate on Starliner’s base. Those airbags are designed to cushion the impact of landing on astronauts inside the spacecraft.While there are no human astronauts on this Starliner. , the spacecraft is carrying ” Rosie the Rocketeer, “a spacesuit-clad anthropomorphic test dummy equipped with sensors to measure what astronauts will feel.

We’re going to be able to measure how the human would receive the Gs during entry, and also as the parachutes deploy and as we land, “Stich said. “We can measure that environment on Rosie and then extrapolate how a human would do in that environment.”: ****************************(Boeing’s CST -) Starliner Space Capsule (Infographic)

After landing, teams from Boeing and NASA will arrive to recover the vehicle (and its Rosie dummy) to see How Starliner and its systems performedduring the trip home.

About the only thing Starliner will not have done during its test flight is the actual docking with the space station. Timing issue aside, the spacecraft fared well during launch and its major systems performed as expected in orbit, Chilton said. Engineers were also able to to deploy and retract Starliner’s docking system to make sure it would work during actual dockings.

But just like launch, landing is a test. that stands apart, Chilton said.

“Not all objectives are created equal,” he added. “Make no mistake. We still have something to prove here on entry tomorrow.”
