ЦитатаStarliner 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.

Назначенный на 23 июня запуск AtlasV 551 (корпорация ULA) скорее всего будет отложен на некоторое время, что следует из обьъявления ULA и пояснения ее руководителя Тори Бруно.

Все дело в новом карбоновом удлиненном сопле двигателя второй ступени RL10C-1-1.

Сообщение ULA 2 часа назад:
Цитата: undefinedЗапуск ракеты ULA #AtlasV 551 с миссией #STP3 для @SpaceForceDOD @USSF_SMC был отложен для оценки готовности ракеты-носителя. Мы работаем с нашим клиентом, чтобы определить следующую доступную возможность запуска.

ЦитатаNASA'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.
