Moment Nasa's historic Artemis II spacecraft launches | BBC News
NASA's Artemis II spacecraft successfully launched with its four-person crew bound for the moon. The launch proceeded nominally through all major milestones including booster separation, main engine cutoff, and core stage separation at 8 minutes 40 seconds into flight.
Summary
The transcript captures the live launch coverage of NASA's historic Artemis II mission, marking humanity's return to lunar missions with a crewed spacecraft called Integrity. The launch sequence proceeded flawlessly through all critical phases, beginning with the ignition of RS25 engines and solid rocket boosters. Within the first minute, the spacecraft went supersonic and passed through max Q (maximum dynamic pressure). At approximately 2 minutes, the solid rocket boosters separated as planned, followed by main engine throttle adjustments. By 3 minutes into flight, Integrity had reached 49 miles altitude and over 5,000 mph, successfully completing launch system jettison. The four crew members - Commander Reed Wiseman, Glover, Cook, and Hansen - officially crossed the boundary into space at 3 minutes 50 seconds, with Wiseman reporting visual contact with the moon. The mission continued through various system checks and trajectory confirmations, with GPS guidance systems coming online and multiple engine performance verifications. The final major milestone captured was the nominal main engine cutoff and core stage separation at 8 minutes 40 seconds, with the spacecraft on proper trajectory for its lunar mission.
Key Insights
- Commander Reed Wiseman confirmed visual contact with the moon destination, stating they had a beautiful moonrise and were headed right at it
- The four crew members Wiseman, Glover, Cook, and Hansen officially crossed the boundary to space with successful communication checks
- Mission control confirmed that only three good main engines were needed for nominal cutoff, though all four engines were performing well
- An abort once around option window opened at 7 minutes 30 seconds that would target splashdown in the Pacific Ocean if needed
- The spacecraft achieved nominal main engine cutoff and core stage separation at 8 minutes 40 seconds, confirming proper trajectory toward the moon

'One if not the largest strikes by Russia on Kyiv since war began'. #Ukraine #Russia #BBCNews
Russia launched one of its largest aerial assaults on Kyiv since the start of the war, involving hundreds of drones and dozens of missiles. While most were intercepted, several struck civilian areas including a metro station, shopping center, and residential block. The attack signals that President Putin remains committed to continuing the war.
At least 82 killed in Chinese coal mine explosion. #China #BBCNews
A gas explosion at the Liucheng New Mine in Shanxi, China killed at least 82 workers and hospitalized over 100, making it the worst mining accident in the country in over a decade. Rescue robots are being deployed to reach potentially trapped survivors in toxic tunnels. The incident raises questions about mine safety despite years of stricter regulations.
DR Congo reports more than 200 Ebola deaths | BBC News
The Ebola outbreak in the Democratic Republic of Congo has killed 204 people across three provinces with 867 suspected cases, marking the worst African outbreak in a decade. The Africa CDC has warned 10 countries are at risk, prompting regional surveillance efforts. Response efforts are severely hampered by the M23 rebel conflict in eastern Congo, which has restricted access to affected territories.
Spirit Airlines shutting down after rescue talks collapse | BBC News
Spirit Airlines has ceased operations after failing to secure government bailout funding, becoming the first major US airline casualty in 25 years. The collapse is largely attributed to the Iran war, which has caused jet fuel prices to nearly double, creating unsustainable cost pressures. Aviation consultant Paul Charles warns that other smaller carriers may face similar fates in the coming days.
Is this the true face of Anne Boleyn? | BBC News
A BBC News segment investigates whether facial recognition technology can identify a true portrait of Anne Boleyn, wife of Henry VIII. A University of Bradford team applied facial recognition to historical sketches, proposing that the traditionally accepted portrait may actually depict her mother. Art historians remain deeply skeptical of the methodology.
