Предлагаете ещё и за пресс-службой НАСА подтирать? (а то тут предлагали уже РИА и ТАСС править, было дело). По теме - это ничего, что основное объявление о трансляции вышло ещё 25 июня (#3116), а затем репетовалось многажджы (#3126, #3133, #3134, #3137, #3139 - только за сегодня 4 раза) или только обращаем внимание на крайний пост? Или предлагаете под каждым постом - расшифровывать, расшифровывать, расшифровывать... А просто единожды запомнить
- UTC = EDT + 4 H
- ДМВ = EDT + 7 H,
если EST - то ещё + 1 H, - видимо не судьба...

With weather at 80 percent go for launch and everything proceeding as planned, optimism and enthusiasm were high at Monday morning’s Ascent Abort-2 flight test preview news conference at Kennedy Space Center in Florida.

“We are incredibly excited,” said Jenny Devolites, Ascent Abort-2 crew module manager and test conductor. “It’s such an honor to be a part of this activity and to have this opportunity.”

The Ascent Abort-2 flight test of the launch abort system for NASA’s Orion spacecraft, featuring a test version of the crew module, will lift off from Space Launch Complex 46 at Cape Canaveral Air Force Station Tuesday, July 2. The four-hour launch window opens at 7 a.m. EDT. NASA TV will broadcast launch activities, starting at 6:40 a.m. A postlaunch briefing is  scheduled for approximately two hours after launch. Audio of this briefing will stream live on the agency’s website.

Orion will help pave the way for Artemis missions with astronauts to the Moon and then Mars.

“This test is extremely important,” said Mark Kirasich, Orion program manager. “Our Launch Abort System is a key safety feature of the spacecraft — it will protect the crew members who fly onboard Orion during the most challenging part of the mission, which is the ascent phase.”

Ascent Abort-2 will verify Orion’s abort system can pull the crew module away from an emergency during its ascent to space. The two main objectives: execute the abort by demonstrating it can be completed end to end, and collect key data. There are approximately 900 sensors — including temperature sensors, pressure sensors and microphones —located throughout the vehicle.

At liftoff, the booster will provide about 500,000 pounds of thrust. It will take 55 seconds to ascend to 31,000 feet, traveling more than 800 mph, at which point the abort will be initiated and the abort motor will ignite. Also igniting will be the attitude control motor, which provides steering.

Twenty-seven seconds after the abort, the jettison motor will ignite, pulling away the Launch Abort System from the crew module. The crew module will then free-fall and descend back to the ocean. As a backup communication system, 12 ejectable data recorders eject into the water in pairs. The highest altitude reached will be about 45,000 feet.

“It’s certainly a very exciting test for us tomorrow because it is so important,” NASA astronaut Randy Bresnik said. “The neat part is the next time this whole Launch Abort System flies, there will be crew underneath it in Artemis 2.”

НАСА испытает систему эвакуации пилотируемого корабля Orion
00:24

ВАШИНГТОН, 2 июл - РИА Новости. НАСА во вторник испытает систему экстренной эвакуации создаваемого для полетов в далекий космос пилотируемого корабля Orion, подробности теста сообщили на брифинге в понедельник представители ведомства.

Испытание пройдет на космодроме на мысе Канаверал (штат Флорида) после 14.00 мск во вторник. Пилотируемая капсула космического корабля Orion поднимется с Земли на высоту приблизительно 9,5 тысячи метров, после чего на 56-й секунде полета будет включен двигатель системы эвакуации. С его помощью капсула "оторвется" от несущего ее корабля, после чего на высоте порядка 13,4 тысячи метров включится двигатель, необходимый для корректировки ориентации капсулы в пространстве и ее безопасного возвращения на Землю. В НАСА сообщили, что весь тестовый полет продлится не более 4 минут.

"Две главные цели нашего теста: во-первых, испытание системы эвакуации, показать, что мы можем сделать это от начала и до конца, и, во-вторых, сбор информации", - сообщила руководитель предстоящего испытания Джэнни Деволитес (Jenny Devolites). По ее словам, за экспериментом будут следить около 900 датчиков, которые будут фиксировать показатели давления, температуры и шума в капсуле корабля.

Она рассказала, что в отличие от реальной ситуации, в ходе теста капсула Orion не будет снабжена парашютами. "Мы подробно испытывали парашюты, и на этот раз их не будет", - рассказала представитель ведомства. По ее словам, в НАСА ожидают, что капсула получит повреждения в результате столкновения с поверхностью океана и впоследствии затонет.

"Это испытание крайне важно ... оно является ключевым моментом в обеспечении безопасности экипажа", - сказал на брифинге в понедельник руководитель программы Orion Марк Кирасич (Mark Kirasich).

Countdown preparations will begin around 1 a.m. EDT (0500 GMT), when members of the booster and Orion teams from the Air Force, Northrop Grumman, NASA and Lockheed Martin will begin arriving at the control center at Cape Canaveral Air Force Station.

Controllers will receive a weather briefing at T-minus 2 hours -- roughly 5 a.m. EDT (0900 GMT) -- and proceed into power-up of the abort test booster at T-minus 90 minutes.

The booster is a single-stage SR118 solid rocket motor from the Air Force's stockpile of decommissioned Peacekeeper missiles. The same type of rocket motor is used on the Minotaur 4 family of satellite launch vehicles.

Ground teams will verify good telemetry connectivity between the vehicle and ground receiving stations, and test the booster's flight termination system, which would be used to destroy the vehicle if it flies off course.

A final poll of the Orion team is planned at T-minus 18 minutes, followed by a check of the readiness of the booster team at T-minus 16 minutes.

Managers will give final authorization to launch at T-minus 6 minutes, 30 seconds.

At about T-minus 5 minutes, the booster will be switched to internal power, and final arming of the rocket is planned at around T-minus 2 minutes.

The SR118 rocket motor will ignite as the countdown reaches zero to propel the 93-foot-tall (28-meter) vehicle off the ground with 500,000 pounds of thrust.

Я ввел в поиск гугл 6:40 EST. Он мне выдал ссылку на сайт для пересчета времени, где было написано EDT. Мне стало интересно, то ли кто-то ошибся, то ли НАСА не переходит на летнее время. И когда же, собственно, смотреть. Оказалось, трансляция начнется в 13:40, а окно для запуска - с 14:00 до 18:00. Ничего не запоминал. Всё проверил по справочникам, строго по заветам Старого.
The trajectory is temporarily deviated. Skybot not to blame.

НАСА переходит, но в пресс-службе сидят, как бы это помягше..., вот Вам ещё ссылка из той же оперы, а здесь они решили вопрос инако - без упоминания типа времени (по умолчанию - мол, и так все знают, какое время в Хьюстоне).

Orion data recorders come with return-to-sender instructions
July 1, 2019 | Stephen Clark

NASA has a plan to retrieve 12 ejectable data recorders released fr om an Orion test capsule in the waters off Cape Canaveral following a launch abort test Tuesday, but local boaters and beachgoers could still find the floating orange devices.

If that happens, NASA wants the recorders back.

The data recorders will register information from early 900 temperature, pressure and acoustic sensors during a three-minute flight of an Orion test capsule Tuesday over Cape Canaveral. The test flight is designed to demonstrate the function of the Orion capsule’s abort system, which would be used to quickly whisk astronauts away from a catastrophic launch failure.

NASA considers the demonstration a critical step before putting astronauts on the spacecraft for missions to the moon.

The Orion test capsule to be flown Tuesday is a simplified, cheaper version fo the spacecraft that astronauts will fly. It’s the same shape and weight of the space-worthy Orion spacecraft, and the test capsule is mounted on top of a modified Peacekeeper missile at Space Launch Complex 46, located near the easternmost point of Cape Canaveral Air Force Station.

The four-hour launch window opens at 7 a.m. EDT (1100 GMT) Tuesday.

Less than a minute after liftoff, an abort rocket on top of the 93-foot-tall (28-meter) vehicle will ignite to quickly pull the test capsule away from the Peacekeeper test booster at an altitude of 31,000 feet (about 9,500 meters). The abort system also has a rocket to control its attitude, or orientation, during the critical abort maneuver.

Around 27 seconds later, a different rocket motor will ignite to separate the abort system from the test capsule. All three major components — the booster, capsule and abort system — will fall into the Atlantic Ocean around 7 miles (11 kilometers) east of Cape Canaveral, wh ere they will impact the sea and sink.

The capsule will transmit data collected during the three-minute test back to receiving stations on the ground before hitting the ocean. Engineers want the information to validate the design of the abort system, and ensure it is ready to save astronauts from a failure during the Orion spacecraft’s ascent into orbit on NASA’s Space Launch System, the huge rocket in development to loft the capsule and its crew toward the moon.

In case there are problems with the real-time telemetry stream, NASA added 12 data recorders to the test capsule. The devices will be jettisoned from the vehicle during its descent into the ocean.

“We have two separate pods, they’re actually military flare dispensers, and they had six recorders in each one, and we eject them in pairs every 10 seconds,” said Don Reed, launch director for the AA-2 mission, in an interview with Spaceflight Now. “So 20 seconds after the LAS (launch abort system) jettisons from the crew module, we start ejecting, so the first pair comes out 20 seconds after the LAS is jettisoned, and then every 10 seconds until all 12 are ejected.”

The recorders are designed to survive the impact with the ocean, and they carry automatically-activating locator beacons to help recovery teams on boats find them.

Each device will record the same data, so finding just one recorder will provide a full backup to the in-flight telemetry data stream.

NASA recovered all of the devices during a rehearsal last year, Reed said.

The recorders are bright orange, and are about the length and width of a large candy bar, although somewhat thicker.

“They float, and they do have a label on them,” said Jenny Devolites, NASA’s test conductor for the abort demonstration. “They also actually have a beacon and a transmitter, so that we can locate them.”

The labels say the the recorders are “property of NASA,” and they have a phone number and email address for the public to contact the agency for officials to come and pick up them up.

“We did practice, so we proved we can find them and recover them, but if you see anything like this tomorrow, let us know,” said Mark Kirasich, NASA’s Orion program manager.

T-minus 1 hour, 15 minutes. The countdown is on track for this morning's Orion abort test at Cape Canaveral.

The latest weather briefing shows all conditions are currently observed "go," and there's an 80 percent probability of acceptable weather during this morning's launch window, which opens at 7 a.m. EDT (1100 GMT).

The only weather concern is with cloud cover that could obscure the view of optical tracking cameras positioned around the Florida spaceport. The weather rules dictate no more than three-eighths sky coverage.

T-minus 56 minutes. Today's test flight will last around three minutes, and reach a maximum altitude of around 44,000 feet (13,400 meters). Here's an overview of the flight sequence:
  • T+00:00: The Orion test vehicle lifts off from pad 46 at Cape Canaveral Air Force Station on top of a modified SR118 solid-fueled rocket motor. The SR118 rocket motor comes from the U.S. Air Force's stockpile of decommissioned Peacekeeper nuclear-tipped missiles and produces about 500,000 pounds of thrust.
  • T+00:55: After heading due east from pad 46, the test vehicle reaches an altitude of 31,000 feet (about 9,500 meters) and a speed of about Mach 1.3. The abort command is triggered at this time, and the Orion capsule's solid-fueled abort motor instantly ignites to pull the craft away from the Peacekeeper booster, which is expected to exhaust its propellant and burn out moments later. The abort motor produces about 400,000 pounds of thrust from four nozzles.
  • T+01:10: The abort system's attitude control motor begins to reorient the Orion test capsule so its heat shield faces toward the ground. The attitude control motor is a solid-fueled rocket with eight variable-thrust nozzles positioned around the circumference of the abort tower. The motor can adjust the thrust of each nozzle to control the vehicle's attitude after an abort by moving the position of pintles inside the rocket, which changes the throat area of each nozzle.
  • T+01:22: The jettison motor on the abort system ignites with around 40,000 pounds of thrust to separate from the Orion test vehicle, once the capsule is in the correct orientation after the abort maneuver. The boilerplate Orion capsule, abort system and spent Peacekeeper rocket motor will all splash down in the Atlantic Ocean in a downrange zone around 7 miles (11 kilometers) east of Cape Canaveral, and are designed to sink on impact.
  • T+01:42: The first pair of 12 data recorders begin ejecting from the Orion capsule. Five more pairs of recorders eject from the vehicle at 10-second intervals up until impact.

An important thing with this test launch. There are NO parachutes. Orion simulator is NOT being recovered. This is literally just an abort motor test. Don’t panic when you don’t see parachutes.
