NASA eyes three dates for mega moon rocket’s maiden launch

NASA has taken a major step toward the highly anticipated maiden launch of its mega moon rocket.

The space agency this week named three dates in late August and early September that currently offer ideal conditions for the launch of its mighty Space Launch System (SLS) rocket and Orion spacecraft as part of the Artemis I mission.

At a briefing on July 20, NASA officials cited August 29, September 2, and September 5 as possible launch dates for the mission, which will involve the Orion spacecraft performing a flyby of the moon before returning to Earth. The selected launch date is likely to be confirmed about a week prior to liftoff.

The mission duration will vary depending on the date, NASA said. So if the SLS launches on August 29 or September 5, the mission will last 42 days, while a September 2 launch will see Orion return 39 days later.

Following the completion of a recent ground-based test involving the SLS rocket, technicians are now making final adjustments to the vehicle in preparation for launch from the Kennedy Space Center in Florida.

Artemis I will be an uncrewed flight to test both the SLS rocket and Orion spacecraft, while Artemis II will take the same path but with a crew on board. Artemis III, which could take place as early as 2025, will aim to put the first woman and first person of color on the surface of the moon in what would be the first astronaut lunar landing in five decades.

NASA’s Artemis program heralds a new era of human space exploration, and involves plans for a long-term lunar presence that could serve as a stepping stone for the first crewed missions to Mars.

The SLS will be one of the most powerful rockets ever to launch, capable of delivering 8.8 million pounds of thrust, 15% more than the 7.5 million pounds offered by the Saturn V, which powered the first astronauts toward the moon in the Apollo missions 50 years ago.

For an idea of the kind of power that will be on display during the SLS’s first launch, take a look at this NASA video showing a ground-based test that involved firing all four of the rocket’s engines at the same time, as if for an actual launch.

Watch this Japanese rocket explode just seconds after launch
Japan's Kairos rocket explodes seconds after launch.

A Japanese rocket exploded just seconds after launching on its maiden flight on Wednesday. The vehicle was uncrewed and no one was hurt in the incident.

Footage of the launch, which was supposed to deploy a government test satellite, shows the 18-meter-tall Kairos rocket erupting into a huge fireball just five seconds after getting airborne. Burning debris falling to the ground also caused a blaze back at the launch site.

Meet NASA’s trio of mini moon rovers set to launch next year
Part of NASA’s CADRE technology demonstration, three small rovers that will explore the Moon together show off their ability to drive as a team autonomously – without explicit commands from engineers – during a test in a clean room at the agency’s Jet Propulsion Laboratory in December 2023.

NASA is ramping up its plans for exploring the moon, not only in terms of preparing to send astronauts there but also rovers. There's the VIPER rover, which will search for water around the lunar south pole, and now NASA is introducing a trio of mini rovers called CADRE, or Cooperative Autonomous Distributed Robotic Exploration. These will work together as a team to map the lunar surface, testing the possibilities of using rovers in groups for future exploration.

The rovers, developed at NASA's Jet Propulsion Laboratory, are just the size of a carry-on suitcase. They are designed to move independently but share data so they can cover more ground than a single rover could. They'll have to work over a lunar day, which is about two weeks, to map out features on the surface and look below ground using radar.
