Re: Mars Sample Return (MSR) Mission

Sample Return Technology Successfully Tested on Xodiac Rocket landing to collect a sample of more than 320 grams of top soil from the surface of the desert floor.

PlanetVac is a surface soil collection system for a sample return mission. The configuration tested would replace a foot pad of a planetary lander spacecraft. The goal is to bring back a sample of surface soil from a celestial body.

“Bringing something back from another planet, celestial body, is the Holy Grail of planetary science,”

The pneumatic sampler foot pad starts operation after the lander touches down on a surface. Compressed gas is injected into the foot pad enclosure, lofting the soil into a cyclone separator for collection.

“What it does is kind of like your vacuum,” The pneumatic sampler foot pad starts operation after the lander touches down on a surface. Compressed gas is injected into the foot pad enclosure, lofting the soil into a cyclone separator for collection.

“What it does is kind of like your vacuum,” “It creates an area of high pressure in the front and uses an area of low pressure in the back to suck up the sample.

“The Flight Opportunities program allowed us to take the PlanetVac idea and actually strap it on to Masten’s rocket putting it in a situation more realistic to what it might encounter in a space mission,” said Spring. “This reduces the risk since we now know it can survive both landing and heating loads as well as the rocket environment and still collect the sample and retain it to come back.”

Re: Mars Sample Return (MSR) Mission

Europe prepares for Mars courier

The campaign aims to bring at least 500 grams of samples back from the Jezero crater that once held a lake and contains an ancient preserved river delta. The rocks in the area preserve information about Mars' diverse geology.

The main challenges are the electric propulsion and power generation. "Not to forget finding and navigating the spacecraft to rendezvous with the football sized orbiting sample over 50 million km away from ground control," adds Orson.

The spacecraft will use technological heritage from ESA's most recently launched science mission, BepiColombo: both use electric propulsion and multi-stage detachable modules.

Once it has collected them in what can be likened to an interplanetary treasure hunt, it will return to the lander platform and load them into a single large canister on the Mars Ascent Vehicle (MAV). This vehicle will perform the first liftoff from Mars and carry the container into Mars orbit.

Re: Mars Sample Return (MSR) Mission

As much as I would want man to get to mars we have yet to do a sample return from mars making use of the small baseline of how we would get men back from mars. Many of the software, sensors for what we design with and communications will tested in making the mission possible.
