NASA counts down for first crewed lunar mission in half a century
NASA is set to launch Artemis 2, the first crewed trip around the Moon since Apollo 8.

CAPE CANAVERAL, Florida: NASA
is set to launch four astronauts as soon as Wednesday (Apr 1) evening on a 10-day flight around the moon, marking the
most ambitious US space mission in decades
and a major step toward returning humans to the lunar surface before China's first crewed landing.
The Artemis II crew of
NASA
astronauts Christina Koch, Victor Glover and Reid Wiseman and Canadian astronaut Jeremy Hansen donned their flight suits and arrived at the launchpad ahead of liftoff scheduled as early as 6:24pm EDT (2224 GMT) from
NASA
's Kennedy Space Centre in Florida.
NASA
mission managers had polled "go" to launch the Artemis II mission's towering, 322-foot (98 m) Space Launch System rocket topped with the astronauts' Orion crew capsule. Clouds rolled over Florida's Space Coast midday, though weather forecasts remain 80 per cent favourable for launch.
The launch could occur as late as 8:24pm in Wednesday's two-hour launch window, just one pad away from where the last moon-bound astronauts of the US Apollo programme lifted off more than half a century ago.

The astronauts had arrived in Florida from Houston on Friday. They awoke on Wednesday about nine hours before launch for breakfast, a weather briefing and pre-mission preparations, before sharing farewell words with family ahead of their 2 pm drive to the launchpad, escorted by armoured vehicles.
They have been in a two-week quarantine leading up to liftoff and spent time with their families over the weekend at the Kennedy Space Centre's beach house, a spot where astronauts rest before blasting off into space.

NASA
on Wednesday morning started filling the SLS core stage with 733,000 gallons of super-cooled propellant that powers the rocket's four RS-25 engines. The pickup truck-sized engines, built by Aerojet Rocketdyne, had powered
NASA
's Space Shuttle for decades.
"Everything is going very well right now," assistant launch director Jeremy Graeber said of the SLS core stage fuelling process.
If a last-minute snag with the rocket pops up, or the weather worsens and triggers a scrub,
NASA
could try again to launch as soon as Friday and until Apr 6, after which it would wait until Apr 30 for its next opportunity.
"Certainly all indications are right now, we are in excellent, excellent shape as we get into count," launch director Charlie Blackwell-Thompson told reporters on Monday.
The launch had originally been planned for as early as Feb 6, and then Mar 6, until a pesky hydrogen leak prompted
NASA
to roll the rocket back to its vehicle assembly building for scrutiny.
FARTHEST TRIP IN HISTORY
The Artemis II mission will send the crew on a winding, nearly 10-day journey around the moon and back, sending them some 252,000 miles (406,000 km) into space - the farthest humans have ever travelled.
The current record for the farthest spaceflight at roughly 248,000 miles is held by the three-man crew of the Apollo 13 lunar mission in 1970, which was beset by technical problems after an oxygen tank exploded and was unable to land on the moon as planned.
Humans have not left Earth's orbit since the final Apollo mission in 1972.
NASA
launched its first Artemis mission without crew in 2022, sending the gumdrop-shaped Orion spacecraft on a similar path around the moon and back.
Artemis II will pose a greater test of Orion and the SLS rocket. The astronauts on board will test critical life-support systems, crew interfaces and communications. They will also take manual control of Orion in space roughly three hours after launch to test its steering and manoeuvrability, a key feature should its automated systems fail.

### Merits
- If a last-minute snag with the rocket pops up, or the weather worsens and triggers a scrub, NASA could try again to launch as soon as Friday and until Apr 6, after which it would wait until Apr 30 for its next opportunity. "Certainly all indications are right now, we are in excellent, excellent shape as we get into count," launch director Charlie Blackwell-Thompson told reporters on Monday.
