NewMars member Void wrote a series of posts on the idea of landing payloads on Mars without having to slow them down to zero velocity for landing. The original series of posts led to creation of a topic, and the consensus was that the idea is indeed practical if payloads can survive the impact. This topic is about a specific variation on that theme.
Post #3 contains a summary of work published in 2022, about a design that uses a small parachute and crumple legs to allow a payload to crash-land safely on Mars.
This topic is available for additional reports on this specific idea.
The original topic in this forum contains the word "ballistic"

This post includes a Google summary of a concept called 'Shield" to land packages on Mars at significant velocities.
The best (and worst) Mars landings of all time | Space
A concept called SHIELD (Simplified High Impact Energy Landing Device) is being developed for low-cost Mars landers that could survive a "high impact" landing, designed to endure a deceleration of up to 1000 g's. This technology would allow smaller, less expensive missions to access Mars and land in more rugged or treacherous areas than traditional methods.
How it works: Instead of relying on complex systems like large parachutes and retro-rockets, SHIELD uses a drag skirt to slow the lander to subsonic speeds and a collapsible base, similar to a car's crumple zone, to absorb the impact.
Purpose: It aims to make Mars exploration more affordable by reducing the mass and complexity of the entry, descent, and landing (EDL) system.
Potential benefits: This could enable missions to investigate a wider range of scientific topics and land in areas that are currently too risky for conventional landers.
Testing: NASA has conducted successful tests of the SHIELD concept, with a prototype surviving an impact with forces far greater than what would be experienced on Mars.
