Kessler syndrome: vertical diffusion rate?

Kessler syndrome: vertical diffusion rate?

- The post asks how quickly debris from a Kessler syndrome cascade in LEO would spread vertically to higher orbits versus remaining in the originating orbital shell. - It notes simulations show rapid lateral spread of debris, especially from large collisions, and suggests higher-inclination fragments might intersect populated near-equatorial orbits

ExoMars Rosalind Franklin Parachute Baked Sterile at ESTEC Ahead of 2028 Mars Mission

ExoMars Rosalind Franklin Parachute Baked Sterile at ESTEC Ahead of 2028 Mars Mission

- A 35-metre, 74-kg parachute for the ExoMars Rosalind Franklin rover was heat-sterilised at ESA’s ESTEC facility in the Netherlands. - The sterilisation completes a planetary protection milestone ahead of the mission’s planned 2028 launch. - The parachute will slow the rover during descent through Mars’ atmosphere. - Work

- Branch Technology developed Freeform 3D Printing to create lightweight lattice structural elements for modular building components. - The process originated from Branch’s work on NASA’s 3D‑Printed Habitat Challenge and a cooperative agreement with Marshall Space Flight Center. - Innovations include custom nozzles for lattice extrusion and basalt fiber‑reinforced

SLS to launch without upper stage for Artemis 3

SLS to launch without upper stage for Artemis 3

- NASA will launch Artemis 3’s SLS without the planned Exploration Upper Stage (EUS). - Decision reflects EUS development and schedule challenges prompting a change to the vehicle configuration. - Agency officials are evaluating alternative mission architectures, interim upper-stage options, and impacts to the Artemis timeline. - Program leadership is conducting risk

Kessler syndrome: vertical diffusion rate?

Kessler syndrome: vertical diffusion rate?

- Questions how a Kessler cascade originating in LEO would spread debris across orbital inclinations and whether higher-inclination orbits accelerate spreading. - Notes simulations showing rapid secondary-collision debris production, especially from large impactors. - Asks how quickly fragments would be carried to higher orbits versus cleared by atmospheric drag at low
