NASA and Boeing Set for Third Starliner Launch Attempt with Sunita Williams today

Following two scrubbed attempts due to technical glitches, NASA and Boeing are making a third push to launch the Starliner spacecraft with astronauts Sunita Williams and Butch Wilmore aboard. This crucial mission serves as the final test before Starliner can begin routine crew rotations to the International Space Station (ISS).

The Importance of the NASA Mission

The success of this Crew Flight Test mission is paramount for both NASA and Boeing. Here's why:

• Final Test Before Regular Crew Flights: A successful mission would pave the way for Starliner to become a regular player in transporting astronauts to and from the ISS, complementing SpaceX's Crew Dragon capsule.

• Week-Long Stay for Testing: Sunita Williams and Butch Wilmore will spend approximately eight days at the ISS, conducting a series of tests on the Starliner to evaluate its performance and ensure its readiness for future crewed missions.

Overcoming Launch Delays

The previous launch attempts on June 1st and 2nd encountered setbacks:

• June 1st Launch Scrub: A ground launch sequencer computer experienced a slow start-up, violating safety protocols and triggering an automatic launch abort just minutes before liftoff.

• June 2nd Launch Scrub: A faulty ground power supply unit was identified as the culprit behind another launch hold.

Fixing the Problem and Moving Forward

Fortunately, the issues have been addressed:

• ULA Replaced Faulty Hardware: Over the weekend, the United Launch Alliance (ULA) replaced the faulty ground power supply unit, ensuring proper functionality.

• Third Launch Attempt Set for June 5th: Based on the resolution of the technical problems, NASA, Boeing, and ULA are proceeding with the third launch attempt.

Launch Window and Weather Forecast

• Launch Window: The launch window for this third attempt opens at 10:52 AM ET (8:22 PM IST) on June 5th and remains open for 120 minutes.

• Favorable Weather Conditions: Weather forecasts predict an 80% chance of favorable conditions for liftoff during this window.

NASA Mission Timeline: Launch to Landing

• Successful Launch: If all goes well, the Starliner capsule, named "Calypso," will dock with the ISS approximately 24 hours after launch.

• Eight-Day Stay on ISS: Williams and Wilmore will spend eight days onboard the ISS, conducting various tests on the Starliner.

• Return to Earth: After completing their mission, the Starliner will undock and return to Earth, performing a parachute-assisted landing in the western United States.

Importance of Safety and Future Implications

While the launch delays have undoubtedly been frustrating, they highlight the critical importance of prioritizing safety before launching astronauts into space. With all systems seemingly "go" for the third attempt, NASA and Boeing remain dedicated to ensuring a successful flight.

A Milestone for the Future of Space Exploration

A successful Starliner mission would mark a significant milestone in the space industry. It represents a crucial step in maintaining a consistent American presence on the ISS through the collaboration between NASA and Boeing, alongside other commercial partners like SpaceX.
