The mission’s architects also tested out a maneuver known as “skip-entry” – the first time it had been practiced with a capsule built for astronauts. It did so at speeds of up to 24,500mph, with atmospheric friction being used to slow the capsule to about 325mph before parachutes were engaged ensuring a dignified splashdown. Nasa was keen to test out the reliability of its new heat shield that was deployed in the last 20 minutes of flight as a means of coping with temperatures of almost 2,760C(5,000F) generated with re-entry into the Earth’s atmosphere. In the course of its 25-day, $4bn flight, Orion spanned 1.4m miles (2.25m km) and came within 80 miles (130km) of the moon during a week-long orbit. Orion blasted off on 16 November from the Kennedy Space Center in Florida’s Cape Canaveral. Delays and cost overruns have bedeviled the program, with storms and fuel leaks forcing launches to be postponed through the summer and autumn. Nasa scientists were especially relieved by the successful return of the Orion capsule given the troubled beginnings of Artemis. Nasa plans an Artemis II flight around the moon and back with astronauts on board perhaps by 2024, with the first human lunar landing to follow with Artemis III potentially the year after. This mission will prepare for a crewed Artemis II mission and subsequent missions that will deliver astronauts to the surface of the Moon and to the lunar Gateway. The success of the first Artemis flight paves the way to further moon missions in quick order. An uncrewed Orion will be tested on Artemis I and travel 40,000 miles past the Moon, farther than any spacecraft built for humans has gone before. “It’s historic because we are now going back into deep space with a new generation.” “I’m overwhelmed,” Nasa’s administrator, Bill Nelson, told Associated Press. A view of Earth as seen from the Artemis 1 Orion capsule more than 9 hours into flight on Nov. Nasa’s mission control complex in Houston declared on Sunday to be an extraordinary day. ![]() ![]() NASA, via Associated Press On Sunday, just after noon Eastern time, the Orion. They had spent three days in the valley of Taurus-Littrow in the longest moon landing of the Apollo era. NASA’s Orion spacecraft captured a view of planet Earth during its trip home from the moon on Sunday morning. On 11 December 1972, two astronauts aboard Apollo 17 – Eugene Cernan and Harrison Schmitt – became the last of 12 moonwalkers. With Artemis missions, NASA will land the first woman and first person of color on the Moon, using innovative technologies to explore more of the lunar surface than ever before. Its aim is to return astronauts to the surface of the moon this decade, and then to create a base there from which to launch explorations of Mars. Orion’s return brings to a completion the first flight of Artemis I, Nasa’s new moon program which has been devised as the follow-on to the Apollo era. “From Tranquility Base to Taurus-Littrow to the tranquil waters of the Pacific, the latest chapter of Nasa’s journey to the moon comes to a close. “Splashdown!” the Mission Control commentator, Rob Navias, announced. ![]()
