NASA and Boeing have decided to stand down from Friday’s launch attempt of the agency’s Orbital Flight Test-2 mission. Currently, launch teams are assessing the next available opportunity. The move allows the International Space Station team time to continue working checkouts of the newly arrived Roscosmos’ Nauka module and to ensure the station will be ready for Starliner’s arrival.

NASA, Boeing and United Launch Alliance now are targeting 1:20 p.m. EDT Tuesday, Aug. 3, for launch of the Orbital Flight Test-2 (OFT-2) with the International Space Station ready for the arrival of the Starliner spacecraft. NASA’s live launch coverage begins at 12:30 p.m. Docking is targeted for 1:37 p.m. Wednesday, Aug. 4.OFT-2, Boeing’s second uncrewed flight, is designed to test the end-to-end capabilities of the new system for NASA’s Commercial Crew Program.

Work continues with Nauka moduleAugust 03, 2021, 07:06 GMTThe integration of the Nauka Multipurpose Laboratory Module into the Russian segment of the ISS continues at the International Space Station. The week, Roscosmos cosmonauts Oleg Novitskiy and Pyotr Dubrov will unload the module and dismantle the equipment that has arrived inside it. In addition, the 65th long-term expedition Russian crew members are beginning to prepare for the upcoming spacewalks. The closest are scheduled for September 2 and 8, 2021. They will be dedicated on the new Nauka module integration on the outside of the International Space Station. The integration itself will take over six months and will require about ten spacewalks of Russian cosmonauts. During this period, cable networks and pipelines will have to be laid, the means of fastening large-sized objects, as well as an airlock and a radiation heat exchanger will be installed currently located on the Rassvet Mini Research Module.The next operation associated with the Nauka module is the Yuri Gagarin (Soyuz MS-18) spacecraft redocking. According to preliminary data from the TsNIIMash Mission Control Center ballistic and navigation support service (part of Roscosmos), the ship's undocking from the Rassvet module and docking with Nauka are scheduled for September 28, 2021. Thus, Soyuz MS-18 will free the docking port for the Soyuz MS-19 spacecraft, which is to launch on October 5.
During pre-launch preparations for the uncrewed test flight of the CST-100 Starliner spacecraft, Boeing engineers monitoring the health and status of the vehicle detected unexpected valve position indications in the propulsion system. The issue was initially detected during check outs following yesterday’s electrical storms in the region of Kennedy Space Center.Consequently, the launch of the Starliner spacecraft to the International Space Station atop a United Launch Alliance Atlas V rocket will be postponed. The launch was scheduled for 1:20 p.m. ET on Tuesday, Aug. 3. Boeing and NASA teams are assessing the situation. The team will provide updates regarding a launch attempt on Wednesday, Aug. 4.
The next United Launch Alliance Atlas 5 rocket from Cape Canaveral, flying with two solid rocket boosters, will launch the second test flight of Boeing's Starliner spacecraft to the ISS on August 4 earliest at 12:57pm EDT.
03.08.2021 17:28ISS orbit altitude correction is scheduled for August 19In order to form ballistic conditions before the launch and docking of the Soyuz MS-19 manned transport vehicle, as well as undocking and landing of the Soyuz MS-18 spacecraft, the specialists of the Russian Mission Control Center will correct the orbital altitude of the International Space Station. According to preliminary data from the ballistic and navigation support service of the TsNIIMash Flight Control Center (part of the Roscosmos State Corporation), on August 19, 2021 at 07:04 Moscow time, the engines of the Zvezda service module will be turned on, which will operate for 47 seconds, and the impulse value will be 0.67 m / s. After this maneuver, the average altitude of the ISS should increase by 1.2 km and amount to 420.84 km.Currently, the crew of the 65th long-term expedition, consisting of Roscosmos cosmonauts Oleg Novitsky and Peter Dubrov and NASA astronaut Mark Vande Hai, who arrived on April 9, 2021 on the Soyuz MS-18 manned spacecraft, as well as crew members Crew Dragon - NASA astronauts Shane Kimbrow and Megan MacArthur, ESA astronaut Tom Peske and Japan Aerospace Research Agency astronaut Akihiko Hoshide.
NASA @NASAAlongside @BoeingSpace, we'll take more time to ensure #Starliner is ready to launch to the @Space_Station. We’re standing down from a Aug. 4 launch attempt & will return the spacecraft to the Vertical Integration Facility for further inspection & testing https://go.nasa.gov/3imebz1
NASA, Boeing Standing Down on Aug. 4 Starliner Launch AttemptNASA and Boeing are standing down from the Wednesday, Aug. 4, launch attempt of the agency’s Orbital Flight Test-2 to the International Space Station as mission teams continue to examine the cause of the unexpected valve position indications on the CST-100 Starliner propulsion system.Early in the launch countdown for the Aug. 3 attempt, mission teams detected indications that not all valves were in the proper configuration needed for launch. Mission teams decided to halt the countdown to further analyze the issue.NASA and Boeing worked through several steps to troubleshoot the incorrect valve indications, including cycling the service module propulsion system valves, within the current configuration of the Starliner and United Launch Alliance Atlas V rocket at Space Launch Complex-41 on Cape Canaveral Space Force Station in Florida.Mission teams have decided to roll the Atlas V and Starliner back to the Vertical Integration Facility (VIF) for further inspection and testing where access to the spacecraft is available. Boeing will power down the Starliner spacecraft this evening. The move to the VIF is expected to take place as early as tomorrow.Engineering teams have ruled out a number of potential causes, including software, but additional time is needed to complete the assessment.NASA and Boeing will take whatever time is necessary to ensure Starliner is ready for its important uncrewed flight test to the space station and will look for the next available opportunity after resolution of the issue.
