A model Sample Recovery Helicopter drives and positions itself over a sample tube during a test in the Mars Yard at NASA's Jet Propulsion Laboratory in Southern California.  Two Sample Recovery Helicopters are slated to fly to Mars as part of the Mars Sample Return campaign. NASA is developing the Sample Recovery Helicopters to serve as backups to the agency's Perseverance rover in transporting sample tubes to the Sample Retrieval Lander.  These helicopters are follow-ons to NASA's Ingenuity Mars Helicopter, which arrived at the Red Planet in the belly of Perseverance in February 2021. The Sample Recovery Helicopters have wheels instead of feet, as well as a small manipulator arm with a two-fingered gripper capable of carrying precious sample tubes.  Testing of the Sample Recovery Helicopters is ongoing. The testbed was made by AeroVironment Inc.  Movie available at https://photojournal.jpl.nasa.gov/catalog/PIA25320

An AH-64 (Apache) Longbow fire control full size radar photographed during icing tests in the Icing Research wind tunnel.  Built at the end of World War II, the Icing Research Tunnel is the oldest and largest refrigerated icing wind tunnel in the world. It can produce winds that travel up to 395 miles per hour and reach temperatures as low as -30 degrees Fahrenheit. The facility simulates ice formation during flight by spraying a cloud of super-cooled water droplets onto an aircraft component or model.

Engineers prepare a small rover – part of NASA's CADRE (Cooperative Autonomous Distributed Robotic Exploration) technology demonstration that's headed to the Moon – for testing in the thermal vacuum chamber behind them at the agency's Jet Propulsion Laboratory in Southern California in October 2023.  Slated to arrive at the Moon in 2024 as part of NASA's CLPS (Commercial Lunar Payload Services) initiative, CADRE is designed to demonstrate that multiple robots can cooperate and explore together autonomously – without direct input from human mission controllers.  A trio of the miniature solar-powered rovers, each about the size of a carry-on suitcase, will explore the Moon as a team, communicating via radio with each other and a base station aboard a lunar lander. By taking simultaneous measurements from multiple locations, CADRE will also demonstrate how multirobot missions can record data impossible for a single robot to achieve – a tantalizing prospect for future missions.  The rover being tested is the first flight model to be completed. Thermal vacuum testing simulates the harsh environment the rovers will face on the journey to the Moon and on the lunar surface: All the air is pumped out of the chamber and the temperature is cycled to high and low extremes.  https://photojournal.jpl.nasa.gov/catalog/PIA25670
