NASA is stacking the Artemis II rocket, implying a simple heat shield fix

21 November 2024 at 17:50

The Space Launch System rocket that will dispatch four astronauts on the first Moon mission in more than 50 years passed a major milestone Wednesday.

NASA said ground teams inside the Vehicle Assembly Building (VAB) at Kennedy Space Center in Florida lifted the aft assembly of the rocket's left booster onto the mobile launch platform. Using an overhead crane, teams hoisted the left aft booster assemblyβ€”already filled with pre-packed solid propellantβ€”from the VAB transfer aisle, over a catwalk dozens of stories high and then down onto mounting posts on the mobile launcher.

This marks the start of stacking for the second SLS rocket earmarked to launch NASA's Artemis II mission and slated to send NASA astronauts Reid Wiseman, Victor Glover, Christina Koch, and Canadian astronaut Jeremy Hansen on a 10-day flight around the far side of the Moon. Artemis II will be the first crewed flight of NASA's Artemis program and the first time people fly on the SLS rocket and Orion spacecraft.

The central piece of NASA's second Space Launch System rocket arrived at Kennedy Space Center in Florida this week. Agency officials intend to start stacking the towering launcher in the next couple of months for a mission late next year carrying a team of four astronauts around the Moon.

The Artemis II mission, officially scheduled for September 2025, will be the first voyage by humans to the vicinity of the Moon since the last Apollo lunar landing mission in 1972. NASA astronauts Reid Wiseman, Victor Glover, Christina Koch, and Canadian mission specialist Jeremy Hansen will ride the SLS rocket away from Earth, then fly around the far side of the Moon and return home inside NASA's Orion spacecraft.

"The core is the backbone of SLS, and it’s the backbone of the Artemis mission," said Matthew Ramsey, NASA's mission manager for Artemis II. "We’ve been waiting for the core to get here because all the integrated tests and checkouts that we do have to have the core stage. It has the flight avionics that drive the whole system. The boosters are also important, but the core is really the backbone for Artemis. So it’s a big day.”

Welcome to Edition 7.03 of the Rocket Report! One week ago, SpaceX suffered a rare failure of its workhorse Falcon 9 rocket. In fact, it was the first time the latest version of the Falcon 9, known as the Block 5, has ever failed on its prime mission after nearly 300 launches. The world's launch pads have been silent since the grounding of the Falcon 9 fleet after last week's failure. This isn't surprising, but it's noteworthy. After all, the Falcon 9 has flown more this year than all of the world's other rockets combined and is fundamental to much of what the world does in space.

Astra finally goes private, again. A long-simmering deal for Astra's founders to take the company private has been finalized, the company announced Thursday, capping the rocket launch company’s descent from blank-check darling to delisting in three years, Bloomberg reports. The launch company's valuation peaked at $3.9 billion in 2021, the year it went public, and was worth about $12.2 million at the end of March, according to data compiled by Bloomberg. Astra's chief executive officer, Chris Kemp, and chief technology officer, Adam London, founded the company in 2016 with the goal of essentially commoditizing launch services for small satellites. But Astra's rockets failed to deliver and fell short of orbit five times in seven tries.
