NASA’s massive new moon rocket arrives at launch pad

NASA’s next-generation rocket system, designed to carry spacecraft to the moon as part of the Artemis mission, has arrived at its launch pad for the first time. The Space Launch System (SLS), standing at 212 feet tall, arrived at Launch Pad 39B at the agency’s Kennedy Space Center in Florida on Friday, March 18, following a 10.5-hour journey from its assembly building.

The rocket was topped with the Orion spacecraft, ready for testing before the uncrewed Artemis I mission to the moon. Subsequent Artemis missions will be crewed, with the aim to put humans back on the moon by 2025. “From this sacred and historical place, humanity will soon embark on a new era of exploration,” said NASA administrator Bill Nelson in a statement. “Artemis I will demonstrate NASA’s commitment and capacity to extend humanity’s presence on the Moon — and beyond.”

To reach the launch pad, the SLS was mounted to a machine called a crawler which transported the 3.5 million pound rocket from the site’s Vehicle Assembly Building. It left the building at 5:47 p.m. ET on Thursday, March 17, and arrived at 4:15 a.m. ET on Friday, March 18.

The rocket is now ready for its final test, called a wet dress rehearsal, in which the launch sequence is carried out and fuel is loaded into the rocket’s tanks. The engines won’t actually ignite, however. If all goes well, the rocket could launch for real in May this year.

“Rolling out of the Vehicle Assembly Building is an iconic moment for this rocket and spacecraft, and this is a key milestone for NASA,” said Tom Whitmeyer, deputy associate administrator for Common Exploration Systems Development at NASA Headquarters in Washington. “Now at the pad for the first time, we will use the integrated systems to practice the launch countdown and load the rocket with the propellants it needs to send Orion on a lunar journey in preparation for launch.”

Astronomers share early images from James Webb’s galaxy survey
Images of four example galaxies selected from the first epoch of COSMOS-Web NIRCam observations, highlighting the range of structures that can be seen. In the upper left is a barred spiral galaxy; in the upper right is an example of a gravitational lens, where the mass of the central galaxy is causing the light from a distant galaxy to be stretched into arcs; on the lower left is nearby galaxy displaying shells of material, suggesting it merged with another galaxy in its past; on the lower right is a barred spiral galaxy with several clumps of active star formation.

One of the major aims of the James Webb Space Telescope is to observe some of the earliest galaxies in the universe, and to do that it needs to be able to see extremely distant objects. But looking at a particular very old galaxy in detail is only half of the problem. To truly understand the earliest stages of the universe, astronomers also need to see how these very old galaxies are distributed so they can understand the large-scale structure of the universe.

That's the aim of the COSMOS-Web program, which is using James Webb to survey a wide area of the sky and look for these rare, ancient galaxies. It aims to study up to 1 million galaxies during over 255 hours of observing time, using both Webb's near-infrared camera (NIRCam) and its mid-infrared instrument (MIRI) camera. While there is still plenty of observing left to do, the researchers in the COSMOS-Web program recently shared some of their first results.
