ՆԱՍԱ-ի «Արտեմիս II» առաքելությունը՝ մանրամասն 10-օրյա լուսնային թռիչքի պլան

"...tightly choreographed..."

"...reads like an astronaut’s field manual..."

"...sweeping loop around the moon and back..."

"...validating the spacecraft and operations that will underpin future lunar landings..."

"...readiness test..."

"...trial runs in deep space..."

"...trajectory holds..."

"...could surpass the human distance mark set during Apollo 13..."

"...skimming thousands of miles past the lunar far side..."

"...free-return path home..."

"...twin boosters and quartet of RS-25 engines generate more than 8.8 million pounds of thrust..."

"...proximity-operations demo..."

"...manually steering back toward the departing upper stage as a stand-in 'target'..."

"...rehearsal for the rendezvous and docking work that will be required at the moon on later missions..."

"...including linkups with a human landing system or the lunar Gateway..."

"...deliberately high and elliptical..."

"...safety cushion that allows a rapid return if systems misbehave..."

"...proving the basics in space..."

"...power, thermal control, avionics, and crew displays..."

"...before committing to the moon..."

"...key engine firing..."

"...timed by orbital mechanics, not convenience..."

"...monitoring cabin pressure, oxygen and carbon dioxide levels, humidity, and water production under real crew metabolic loads..."

"...stretch beyond the reach of GPS and near-Earth relay satellites..."

"...crucial proving ground for sustained operations far from Earth..."

"...long burn known as translunar injection..."

"...commits the crew to deep space..."

"...free-return..."

"...gravity alone will arc Orion around the moon and bend it back toward Earth even if later engine firings are unavailable..."

"...NASA favors this profile for its built-in resiliency, a lesson embedded since Apollo..."

"...roughly four-day cruise..."

"...small course-correction burns trim the path..."

"...rehearse emergency procedures..."

"...evaluate radiation-protection techniques inside the cabin..."

"...Building on lessons from Artemis I’s sensor-laden mannequins..."

"...try a 'storm shelter' configuration using stowed equipment to add shielding against solar particle events..."

"...enters the moon’s gravitational sphere of influence..."

"...arcs over the far side at an altitude targeted between about 4,000 and 6,000 miles above the surface..."

"...depending on launch geometry..."

"...roughly three-quarters of an hour behind the lunar limb..."

"...planned blackout managed by DSN handovers and onboard autonomy..."

"...photo-op and milestone moment..."

"...moon framed large in the windows..."

"...expected to edge past the Apollo 13 record of about 248,655 miles from Earth..."

"...document the far side—terrain Apollo astronauts never saw..."

"...mission controllers track spacecraft behavior without ground contact..."

"...no major braking burn is required..."

"...combined pull of Earth and moon guides Orion onto its homebound leg..."

"...manual-flying exercises and systems checks continue en route..."

"...trajectory tweaks to hit the reentry corridor precisely..."

"...jettisons its service module..."

"...exposing the heat shield for atmospheric entry at roughly 24,500 miles per hour..."

"...Plasma sheaths the capsule, briefly cutting radio contact..."

"...temperatures peak near 3,000 degrees Fahrenheit..."

"...sequence of drogues and three main parachutes then slows the vehicle for splashdown off the Southern California coast..."

"...U.S. Navy amphibious teams aim to secure capsule and crew within about two hours..."

"...Every block of this itinerary maps directly to future needs..."

"...precision piloting readies crews for rendezvous with a lunar lander..."

"...life-support trials buy down risk for longer stays..."

"...deep-space comms prove the ground architecture that will support the Gateway..."

"...NASA’s flight directors and the Aerospace Safety Advisory Panel have stressed that crewed certification hinges on these demonstrations..."

"...from avionics performance to heat shield margins..."

"...Artemis I showed Orion could endure deep space without a crew..."

"...logging more than a million miles and a distant lunar orbit..."

"...Artemis 2 is the human-in-the-loop exam..."

"...If it runs this playbook cleanly—from the first manual fly-around to the last parachute reefing—it clears the path for the first lunar landing attempt of the program and, ultimately, a sustainable cadence of missions that return humans to the moon’s surface..."
