ЦитироватьStarliner test flight next on ULA's launch schedule after military mission delay
January 25, 2021 Stephen Clark
The U.S. Space Force has decided to delay the planned late February launch of two military satellites aboard a ULA Atlas 5 rocket to "evaluate readiness" of one of the payloads, giving officials a window to move forward the liftoff of an unpiloted test flight of Boeing's Starliner crew capsule to no earlier than March 25.
The launch of the military's Space Test Program-3, or STP-3, mission was previously scheduled Feb. 26 on an Atlas 5 rocket from Cape Canaveral Space Force Station. The STP-3 mission will deliver two military spacecraft into a geosynchronous orbit more than 20,000 miles over the equator.
A spokesperson for the Space and Missile Systems Center said the STP-3 launch has been delayed to "evaluate readiness" of one the military satellites, named STPSat6, and "ensure mission success of the primary payload."
STPSat 6 hosts several payloads and experiments, including the National Nuclear Security Administration's Space and Atmospheric Burst Reporting System-3 payload, which is designed to detect nuclear detonations from orbit. NASA's Laser Communications Relay Demonstration experiment and several more payloads are also flying on the STPSat 6 spacecraft.
A smaller satellite named LPDE 1 will ride into orbit with STPSat 6. The LPDE 1 spacecraft is designed to accommodate experimental payloads and small satellites, which could be deployed from the parent satellite in orbit.
The STP-3 mission is also a milestone mission for ULA because it will be the first Atlas 5 launch with U.S.-built payload fairing. The 5.4-meter-diameter (17.7-foot) shroud is identical in size to payload fairings that flew on previous Atlas 5 flights, but those were built by RUAG Space in Switzerland.
But the new fairings are built by RUAG technicians inside ULA's rocket factory in Decatur, Alabama, using updated manufacturing techniques. The same fairing design is intended to fly on ULA's next-generation Vulcan Centaur rocket.
The Space Force's Space and Missile Systems Center said the STP-3 mission does not have a new target launch date.
With the STP-3 mission out of the way, ULA's first launch of 2021 will carry Boeing's Starliner spacecraft into orbit on a test flight to the International Space Station.
The unpiloted demonstration mission, named Orbital Flight Test-2, is a repeat of Boeing's OFT-1 test flight in December 2019. Software problems on the OFT-1 mission prevented the Starliner spacecraft from docking with the space station, forcing a premature landing under parachutes at White Sands Space Harbor, New Mexico.

U.S. media accreditation has opened for an upcoming rocket launch with a NASA payload that aims to enhance communications capabilities for the agency's future missions, including the potential to increase bandwidth 10 to 100 times more than radio frequency systems.

NASA's Laser Communications Relay Demonstration (LCRD) will fly as a payload on STPSat-6, the primary spacecraft of the third Space Test Program (STP-3) mission for the Department of Defense. STP-3 is scheduled to lift off on a United Launch Alliance Atlas V 551 rocket Wednesday, June 23, from Space Launch Complex 41 at Cape Canaveral Space Force Station in Florida.

Members of the media who are U.S. citizens or permanent residents and interested in covering the launch must submit a media access application and registration form to Space Launch Delta 45 at: 45swpa@us.af.mil. Requests should be submitted no later than 5 p.m. EDT Friday, June 11. Applicants will be notified of acceptance Tuesday, June 15. NASA subject matter experts will be available for interviews the day before launch.

LCRD represents a significant step toward making operational laser, or optical, communications a reality. The payload's microwave-oven-size optical modules will send and receive data over infrared lasers – not visible to the human eye – at 1.2 gigabits per second from geosynchronous orbit to Earth. At that rate, it's possible to download a two-hour movie in about 20 seconds.

Engineers will beam data between LCRD and optical ground stations located in Table Mountain, California, and Haleakalā, Hawaii, once it is positioned more than 22,000 miles above Earth. Experiments will allow engineers to refine the transmission process, study different operational scenarios, and refine tracking systems. LCRD will generate essential data and information to prepare laser communications systems for operational missions, as engineers cannot replicate the same conditions with ground tests.

Later in its mission, LCRD will conduct optical communications relay services with a future terminal on the International Space Station, which is expected to launch on a commercial resupply services mission in 2022. These operations could prove the viability of using laser communications in future crewed missions to the Moon and Mars.

The LCRD mission is led by NASA's Goddard Space Flight Center in Greenbelt, Maryland. Partners include NASA's Jet Propulsion Laboratory in Southern California and the MIT Lincoln Laboratory. LCRD is funded through NASA's Technology Demonstration Missions program, part of the agency's Space Technology Mission Directorate, and the Space Communications and Navigation (SCaN) program within the agency's Human Exploration and Operations Mission Directorate. 

STP-3 is a co-manifested spacecraft launch mission managed by the U.S. Space Force's (USSF) Space and Missile Systems Center. The STP-3 mission matures technology and reduces risk for the Department of the Air Force, USSF, and defense and civil partners. The primary spacecraft on STP-3 is STPSat-6 and the rideshare spacecraft is the Long Duration Propulsive Evolved Expendable Launch Vehicle (EELV) Secondary Payload Adapter (ESPA) -1, or LDPE-1. Northrop Grumman built both spacecraft.

ЦитироватьNASA's James Webb Space Telescope, which will be the premier observatory of the next decade, remains on schedule for a launch readiness date no earlier than Oct. 31, 2021.

Webb will ship to the launch site in August with little to no schedule margin; launch processing will take two months. The observatory has completed all the post-environmental testing deployments, and it is in its final integration and folding stages. Final stow, closeout, and pack and ship are imminent. We are working closely with the European Space Agency (ESA) and Arianespace on establishing the launch date. We will launch approximately four months after the first launch of the Ariane 5 this year, which is scheduled for late July. Webb has no launch date constraints; hence, it can launch almost any day of the year...

Launch of NASA's Laser Communications Relay Demonstration — LCRD Official Launch Coverage
  NASA
Watch the liftoff of our Laser Communications Relay Demonstration (LCRD) from Cape Canaveral Space Force Station in Florida. The two-hour launch window opens Dec. 5, 2021 at 4:04 a.m. EST.
Laser communications offer data rates higher than traditional radio frequency systems, allowing more data per transmission. Once in orbit, LCRD will demonstrate the benefits of using infrared lasers to communicate information from space, including reduced size, weight, and power requirements for a communications system on a spacecraft. A smaller size means more room for science instruments. Less weight means a less expensive launch. Less power means less drain on the spacecraft's batteries. All of this enables further exploration.
LCRD is a NASA payload aboard the Department of Defense's Space Test Program Satellite-6 (STPSat-6). STPSat-6, part of the Space Test Program 3 (STP-3) mission, will launch on a United Launch Alliance Atlas V 551 rocket from the Cape Canaveral Space Force Station in Florida. STP is operated by the United States Space Force's Space Systems Command.

ЦитироватьВ рамках миссии Space Test Program-3 (STP-3) ракета, в частности, должна вывести на геостационарную орбиту высотой 35,4 тыс. км экспериментальный военный спутник STPSat-6 с системой Space and Atmospheric Burst Reporting System-3 для отслеживания космических и атмосферных взрывов, который создан Национальным управлением ядерной безопасности США (NNSA).
      Он обеспечивает обнаружение ядерных взрывов и отслеживание данных о космической среде и предназначен для дополнения детекторов ядерной детонации на борту современных космических аппаратов GPS.
      Ракета также выведет на орбиту в интересах NASA экспериментальный спутник LCRD - демонстратор ретранслятора лазерной космической связи (Laser Communications Relay Demonstration). По данным американского космического агентства, на аппарате будет апробирована технология инфракрасной лазерной ретрансляции, которая позволит спутникам передавать данные двухсторонней связи между Международной космической станцией и Землей с геосинхронной орбиты на Землю со скоростями порядка 1.2 Гбит. Помимо этого, система лазерной связи позволит значительной уменьшить вес, габариты и энергопотребление по сравнению с другими аппаратами связи. Спутник должен будет проработать на орбите два года.
      Кроме того, ракета несет адаптер полезной нагрузки LDPE-1, предназначенный для развертывания малых военных спутников, и еще шесть аппаратов космического слежения в интересах Пентагона, технические данные которых засекречены.
      Все космические аппараты будут выведены на орбиту примерно через семь часов после старта ракеты.
      Двухступенчатая ракета-носитель Atlas V создана компанией ULA, которая является совместным предприятием корпораций Boeing и Lockheed Martin, осуществляющим запуски в интересах Пентагона и американского разведывательного сообщества. Она имеет несколько конфигураций, которые отличаются количеством твердотопливных ускорителей и забрасываемой на орбиту полезной нагрузкой.
      На ее первой ступени используются двухкамерный жидкостный ракетный двигатель РД-180 производства российской компании НПО "Энергомаш".

T-minus 2 hours and counting. The countdown clock is ticking again, as the ULA launch team marches toward liftoff of an Atlas 5 rocket at 4:04 a.m. EST (0904 GMT) with the STP-3 mission.
There is one more built-in hold in today's countdown, expected at T-minus 4 minutes. That hold is expected to last 30 minutes.
A thermal conditioning procedure known as chilldown will begin shortly to prepare the plumbing on the Atlas 5's mobile launch platform for the transfer of super-cold cryogenic propellants into the rocket.
Once cryogenic tanking begins, nearly 66,000 gallons of liquid hydrogen and liquid oxygen will be loaded into the two-stage Atlas 5 rocket.

12/07/2021 09:47 Stephen Clark
Liquid oxygen is now flowing into the Atlas 5's Centaur upper stage at Cape Canaveral's Complex 41 launch pad. About 4,150 gallons of the cryogenic propellant, chilled to minus 298 degrees Fahrenheit, will be burned by the Centaur's single Aerojet Rocketdyne RL10 engine along with the liquid hydrogen to be loaded aboard later in the countdown.
Three burns by the Centaur's RL10 engine over a six-and-a-half hour span are planned on this morning's mission to inject the STPSat 6 and LDPE 1 satellites into a near-circular geosynchronous orbit more than 22,400 miles (36,100 kilometers) above the equator.

12/07/2021 10:11  Stephen Clark
Chilldown of the liquid hydrogen transfer lines at Complex 41 is getting started now. This is a step in preparation for loading the super-cold fuel, stored at minus 423 degrees Fahrenheit, into the Centaur upper stage.

The Centaur liquid oxygen tank is now being topped off after reaching the 96 percent full mark.

12/07/2021 10:15  Stephen Clark
After initially pumping liquid oxygen into the Atlas 5's first stage in a slow-fill mode, the cryogenic oxidizer is now being pumped into the rocket in the fast-fill mode.
The Atlas 5's first stage is also known as the Common Core Booster, and it holds 48,800 gallons of liquid oxygen, which will be consumed by the RD-180 main engine in a mixture with RP-1 kerosene loaded into the rocket before the countdown.

Разгонный блок Centaur Atlas 5, приводимый в движение двигателем Aerojet Rocketdyne RL10, выведет два спутника Space Force на геостационарную орбиту с последовательным запуском трех ракет в течение шести с
половиной часов.
Два спутника содержат множество технологических прототипов и экспериментов. Военные инженеры проверят их готовность к использованию в будущих оперативных космических полетах.
Запуск спонсируется военной программой космических испытаний, которая контролирует многие экспериментальные космические миссии министерства обороны. На более крупном из двух спутников на ракете Atlas 5, названном STPSat 6 и построенном Northrop Grumman, размещен эксперимент НАСА по лазерной связи и полезная нагрузка для Национального управления ядерной безопасности, предназначенная для обнаружения ядерных взрывов для проверки соблюдения международных договоров.
Военные не раскрывают подробностей других экспериментов в рамках миссии, но официальные лица заявили, что они, как правило, будут тестировать технологии, связанные с осведомленностью о космосе, мониторингом космической погоды и связью.
Спутник совместного использования под названием Long Duration Propulsive ESPA, или LDPE 1, также выходит на орбиту на ракете Atlas 5. Он устанавливается на ракету под STPSat 6 внутри обтекателя полезной нагрузки диаметром 17,7 футов (5,4 метра).
LDPE 1 проводит собственные технологические эксперименты и будет иметь собственную двигательную установку для маневрирования в космосе. Космический аппарат способен выводить на орбиту небольшие спутники. Когда его спросили, военные не подтвердили, есть ли в экспериментах с космическим кораблем LDPE 1 какие-либо развертываемые малогабаритные спутники.

Походу, в 2021 году идём на рекорд по количеству запусков ракет-носителей космического назначения за всю историю космонавтики. ;D

Да врятли. Там под 139 было в 67-м, если верит Вики.
Сейчас 125, и до конца года 3 недели.
Хотя может быть. Планируется с датами в этом году еще 13-15.

Но в 1969 году до орбиты долетело только 110.
Так что по количеству успешных вполне можем побить.

Atlas V launches STP-3
  SciNews
A United Launch Alliance (ULA) Atlas V 551 launch vehicle launched the Space Test Program-3 (STP-3) mission for the U.S. Space Force's (USSF) Space Systems Command (SSC), from Space Launch Complex 41 (SLC-41) at Cape Canaveral Space Force Station, Florida, on 7 December 2021, at 10:19 UTC (05:19 EST). The primary spacecraft is STP Satellite (STPSat)-6 and the rideshare spacecraft is the Long Duration Propulsive Evolved Expendable Launch Vehicle (EELV) Secondary Payload Adapter (ESPA) (LDPE) – 1. STPSat-6 carries nine payloads including the Space and Atmospheric Burst Reporting System 3 (SABRS-3), NASA's Laser Communication Relay Demonstration (LCRD) payload and several Department of Defense Space Experiments Review Board space weather and situational awareness payloads.

The Atlas 5's STP-3 mission will last seven hours and 10 minutes from launch until separation of the second of two military tech demo satellites in geosynchronous orbit. That's the longest Atlas rocket flight in the program's more than 60-year history. https://spaceflightnow.com/2021/12/06/ula-to-set-rocket-endurance-record-on-next-launch/...

MECO-3! The third burn by the Centaur upper stage is complete, finishing powered flight for the launch of #STP3 aboard the #AtlasV rocket. Standing by for the first payload deployment.
.
Separation confirmed! The United Launch Alliance #AtlasV rocket has released the STPSat-6 satellite into space for the U.S. @SpaceForceDoD and @NASALaserComm.

РБ "Центавр" 8 часов в активной фазе - это случаем не рекорд для кислородно-водородного РБ. Сколько он топлива потерял за счёт испарения?

TLEs now out for the STP-3 launch: STPSAT-6, LDPE-1  in 36096 x 36112 km x 0.1 deg orbits, Centaur AV-093 made a depletion burn to 36126 x 38655 km x 0.1 deg

A new object cataloged from the STP-3 launch in super-sync orbit of 35990 x 36117 km x 0.1 deg, presumably a payload ejected from LDPE-1. @AFResearchLab is this ASCENT, or something else?

A new object cataloged from the LDPE-1 launch, 2021-118E. Unclear so far if another debris object or one of the payloads deploying from LDPE-1 (guessing will be the latter)

The object 2021-118E ejected from LDPE-1 on Jan 25 is confirmed by Space-Track to be AFRL's ASCENT satellite.
