Boeing’s Starliner astronaut taxi is preparing for a key check of its programs forward of carrying people. The spacecraft was scheduled to launch on an uncrewed mission and try to succeed in the Worldwide House Station on July 30, nevertheless it has been delayed indefinitely following a docking incident with a Russian module and newly found valve points on the Starliner spacecraft.
On July 29, NASA and Boeing introduced that they’d stand down from the July 30 launch try, suspending to Aug. 3. The choice got here as NASA and Roscosmos evaluated a scenario on the Worldwide House Station involving the newly arrived Nauka module unexpectedly firing its thrusters, briefly interfering with the station’s orientation.
Then on Aug. 3, NASA and Boeing determined to face down from backup launch alternatives on each Aug. 3 and Aug. 4, as officers found a valve problem on the Starliner spacecraft. The Altas V rocket is scheduled to roll again from the launch web site to the Vertical Integration Facility on Wednesday morning. The following accessible launch window has not but been introduced.

Associated: Easy methods to watch Boeing launch its 2nd Starliner check flight for NASA
The mission, referred to as Orbital Flight Check 2 (OFT-2), will probably be an important milestone for Boeing, which was unable to succeed in that vacation spot with Starliner’s first check flight in December 2019. After finishing a radical investigation in July 2020, Boeing and NASA carried out 80 “corrective actions” to arrange Starliner for a do-over of the OFT mission. If all goes nicely, NASA astronauts will quickly start flying astronauts to the house station for NASA.
Here is a whole information to all the pieces it is advisable know in regards to the OFT-2 mission — together with easy methods to see the launch and all associated dwell occasions on-line and in-person — and what this historic mission will imply for NASA and the business spaceflight trade.
When is the launch?
Editor’s be aware: The next webcast schedule is *** NO LONGER UP TO DATE *** as Boeing and NASA haven’t but selected the subsequent launch alternative for OFT-2 following a collection of delays in July and August. We are going to replace this part with new webcast particulars as soon as that info turns into accessible.
The Starliner mission, also called Orbital Flight Check 2 (OFT-2), at the moment has no deliberate launch date. It was scheduled to carry off July 30 at 2:53 p.m. EDT (1853 GMT), then delayed to Aug. 3 at 1:20 p.m. EDT (1720 GMT) earlier than Boeing and NASA determined to delay the mission indefinitely and return Starliner to the manufacturing facility to repair some malfunctioning valves on the spacecraft.
The timing of the launch is all the time topic to vary as a result of technical, climate or different components. Launch climate forecasts will probably be supplied by the U.S. House Pressure’s forty fifth Climate Squadron.
You may watch dwell protection of the mission right here at House.com, courtesy of NASA Tv. NASA’s launch broadcast will start with prelaunch actions and finish after Starliner’s orbital insertion; dwell protection will resume when Starliner approaches the house station for docking about 24 hours after liftoff.
Starliner ought to attain its preliminary orbit about 31 minutes after liftoff. After the orbit insertion maneuver, the spacecraft will start a 24-hour orbital chase to meet up with the Worldwide House Station for rendezvous and docking.
About 18 hours after Starliner docks, the Expedition 65 astronauts onboard the house station will open the hatch and enter the Starliner car for an inspection. NASA has not but introduced a brand new schedule for hatch opening, however count on that second, too, will stream dwell on NASA’s channels and on House.com.
Starliner will spend lower than per week docked on the house station earlier than returning to Earth for a parachute-assisted touchdown at White Sands House Harbor in New Mexico; NASA has not but introduced a brand new touchdown date for the mission.
The place will Starliner carry off?
Boeing will launch Starliner from House Launch Advanced 41 at Cape Canaveral House Pressure Station in Florida, a busy launch port located close to NASA’s Kennedy House Heart. The launch space is about an hour east of Orlando adjoining to the Atlantic coast, offering for a secure area for rocket stage drops and general launch actions.
Cape Canaveral House Pressure Station is without doubt one of the United States’ first launch websites and had its title formally modified from Cape Canaveral Air Pressure Station in late 2020.
This is identical facility from which the primary U.S. satellite tv for pc, Explorer 1, launched in 1958 and the place among the first American astronauts launched for house and Earth orbit. Quite a few uncrewed planetary probes have additionally departed Cape Canaveral over the a long time, with some reaching into interstellar house.
Easy methods to see the launch in individual
Planning to observe the launch in individual? Because of the ongoing COVID-19 pandemic, NASA is limiting facility entry to the general public and just some media will probably be there in individual. Spectators wishing to view the launch from the close by NASA Kennedy House Heart should buy tickets on-line prematurely. (However spectators beware: With the rising variety of COVID-19 circumstances in Florida, NASA could very nicely find yourself canceling the occasion at KSC.)
Viewers alongside the japanese seaboard of america could possibly catch a glimpse of the rocket hovering by the sky, climate and daylight allowing. Nevertheless, if the launch happens through the daytime, it might be tough to look at.
What’s on board?
Whereas Starliner will probably be uncrewed for the OFT-2 mission, the commander’s seat can have a passenger: Rosie the Rocketeer, Boeing’s anthropometric check system. Rosie additionally flew to house briefly through the first Starliner mission in December 2019 and was outfitted with 15 sensors to guage the stresses of spaceflight on the human physique. However for OFT-2, the “dummy” will not be accumulating any extra knowledge.
“Rosie’s there, however she is basically a ballast,” John Vollmer, vice chairman and program supervisor of Boeing’s business crew program, mentioned in Tuesday’s prelaunch briefing. “We’re taking measurements — we have put sensors within the seats and different places within the car, as we discovered that we thought that may be extra worthwhile since we would gotten the info from Rosie on the primary flight.”
A lot of Starliner’s cargo will probably be easy provides and gear for the Expedition 65 crew aboard the Worldwide House Station. Starliner will deliver greater than 400 kilos (180 kilograms) to the orbiting laboratory, and upon departure the spacecraft will return to Earth with greater than 550 lbs. (250 kg) of cargo, in response to NASA.
Starliner can even fly commemorative issues. OFT-2 will embody 14 banners from traditionally Black faculties and universities (HBCUs), Silver Snoopy pins (historically given to NASA astronauts who instantly contribute to human spaceflight success) and Rosie the Riveter commemorative cash to honor the practically 19 million American girls who contributed to the aerospace trade through the Second World Struggle.
Different gadgets aboard the spacecraft embody American flags and an ID card signed and utilized by Boeing’s founder, Invoice Boeing, to journey the U.S. by air. The identical card additionally flew onboard OFT-1.
What’s Starliner’s mission?
The general aim of Starliner’s OFT-2 mission is to rocket a spacecraft to the Worldwide House Station, dock with it to trade provides and gear, and execute a secure splashdown within the Atlantic Ocean. That is an uncrewed check mission to make sure that the important thing milestones of an astronaut flight are potential in order that Starliner might be licensed to hold astronaut crews.
In 2014, each Boeing and SpaceX acquired business crew growth contracts from NASA, collectively valued at $6.8 billion, to deliver astronauts to house as a substitute for the house shuttle car that retired in 2011. Within the interim, Russia’s Soyuz spacecraft introduced all NASA astronauts to the ISS.
SpaceX’s Crew Dragon started operational flights with astronauts in 2020, lowering NASA’s want to make use of Soyuz spacecraft. Nevertheless, Boeing encountered technical issues which have delayed Starliner human flights. Throughout Starliner’s final check try in December 2019, the spacecraft skilled a collection of glitches that stranded the car within the unsuitable orbit to succeed in the Worldwide House Station.
The spacecraft landed safely after its failed try to succeed in the ISS, and since then NASA and Boeing have been working collectively to repair dozens of points recognized through the 2019 flight.
Media stories counsel that if Boeing’s OFT-2 passes its flight certification, the corporate could fly astronauts on a crewed check flight in late 2021. (NASA and Boeing officers declined to provide a extra particular timeframe for the primary crewed mission throughout an OFT-2 prelaunch information briefing on July 27; that was earlier than the most recent collection of delays.)
OFT-2 mission timeline & flight profile
Editor’s be aware: The occasions and dates listed on the next schedule are *** NO LONGER UP TO DATE *** as Boeing and NASA haven’t but selected the subsequent launch alternative for OFT-2 following a collection of delays in July and August. Nevertheless, the flight profile probably won’t change for later launch alternatives. We are going to replace this part with new webcast particulars as soon as that info turns into accessible.
Ought to the schedule maintain, Starliner will blast off aboard a United Launch Alliance Atlas V rocket at
1:20 p.m. EDT (1720 GMT) on Tuesday (Aug. 3) from House Launch Advanced-41 on Cape Canaveral House Pressure Station in Florida.
The spacecraft will attain its preliminary orbit roughly 31 minutes later, after which get able to dock with the Worldwide House Station. Docking is scheduled to happen roughly 24 hours after liftoff.
NASA says the spacecraft will stay docked to the ISS for about 5 to 10 days earlier than coming again to Earth. Starliner will try to land at White Sands House Harbor in New Mexico on the identical day that it undocks from the house station. Via the entire course of, Boeing and NASA will probably be assessing and testing the spacecraft’s efficiency to attempt to certify the spacecraft to ferry astronauts.
A few of the issues NASA desires to see are the profitable in-orbit operation of all main spacecraft programs, good efficiency of steering, navigation and management programs by launch, orbit and re-entry, and secure acoustic and vibration ranges for astronauts. Starliner can even have to satisfy all its fundamental mission necessities of launching, docking and touchdown to a level that’s operational and secure for astronauts.
Earlier than the latest delays, NASA had pledged to place astronauts on board Starliner for a crewed check flight in 2021, so long as OFT-2 meets its aims. “NASA and Boeing will search for alternatives towards the top of this 12 months to fly Starliner’s first crewed mission to the house station,” the company mentioned in a latest assertion. Nevertheless, that timeline will probably be affected by Starliner’s ongoing delays.
That first astronaut mission, referred to as Crew Flight Check, will go to house with veteran NASA astronauts Barry “Butch” Wilmore, Nicole Mann and Mike Fincke. The company says that the crew will stay in house for “a number of months,” however did not specify if that may be a standard six-month rotation. Typically the schedule is adjusted for operational causes, and as a comparability level, SpaceX’s first crewed check flight in 2020, Demo-2, was about two months lengthy.
Crew Flight Check might want to go its main milestones to permit Starliner to get full certification to haul astronaut crews to house repeatedly. As soon as that occurs, NASA can have two business crew automobiles to make use of (Starliner and Crew Dragon) for all its astronaut flights.
Even when the 2 business crew automobiles are operational, NASA nonetheless could use Russian Soyuz seats occasionally. The company has pledged to place Russian cosmonauts aboard American business crew automobiles in trade for Soyuz seats for NASA astronauts, however that association could also be delayed till 2022.
