Artemis II: Crewed lunar flyby readies for launch as Orion braking test exposes critical safety risk
Next month NASA will launch Artemis II: four astronauts aboard Orion on SLS for a 10-day lunar flyby, the first human return beyond LEO since 1972. The mission depends on a critical lunar braking burn — Orion's 8,280 km/h approach must lose ~2,900 km/h or the crew could be stranded.
