THK has developed its best-performing, high-speed rotary bearing ever: the High-Speed, Double-Row Angular Contact Ring BWH. This rotary bearing has balls aligned inside a cage between the inner and outer rings and is part of the THK Rotary Series, along with the cross-roller ring. The main features of this product are its ability to receive loads in all directions as well as its high rigidity and rotational accuracy, which are equal to that of cross-roller rings. By adopting a new structure to change the rolling elements from rollers to balls, this product achieves the greatest high-speed performance ever offered by THK.

According to PBC Linear, their new non-captive linear actuators are different from the more common external versions of lead screw-driven linear actuators because they allow the lead screw to completely pass through the motor. This fundamental difference offers advantages for designs that have limited space available or for engineers looking to shrink the overall size of their design package.

NASA's Mars Perseverance rover's descent stage was recently stacked atop the rover at Kennedy Space Center, and the two were placed in their back shell. The Ingenuity helicopter can be seen attached to the rover's underside (lower center of the image). [Image credit: NASA/JPL-Caltech]
Engineers working on NASA's Perseverance rover mission at the Kennedy Space Center in Florida have begun the process of placing the Mars-bound rover and other spacecraft components into the configuration they'll be in as they ride on top of the United Launch Alliance Atlas V rocket. The launch period for the mission opens on July 17 -- less than two months from now.
Called "vehicle stacking," the process began on April 23 with the integration of the rover and its rocket-powered descent stage. One of the first steps in the daylong operation was to lift the descent stage onto Perseverance so that engineers could connect the two with flight-separation bolts.
When it's time for the rover to touch down on Mars, these three bolts will be released by small pyrotechnic charges, and the spacecraft will execute the sky crane maneuver: Nylon cords spool out through what are called bridle exit guides to lower the rover 25 ft (7.6 m) below the descent stage. Once Perseverance senses it's on the surface, pyrotechnically fired blades will sever the cords, and the descent stage flies off. The sky crane maneuver aims to ensure Perseverance will land on the Martian surface free of any other spacecraft components, eliminating the need for a complex deployment procedure.

"Attaching the rover to the descent stage is a major milestone for the team because these are the first spacecraft components to come together for launch, and they will be the last to separate when we reach Mars," said David Gruel, the Perseverance rover assembly, test, and launch operations manager at NASA's Jet Propulsion Laboratory in Southern California, which manages rover operations. "These two assemblies will remain firmly nestled together until they are about 65 ft [20 m] over the surface of Mars."
On April 29, the rover and descent stage were attached to the cone-shaped back shell, which contains the parachute and, along with the mission's heat shield, provides protection for the rover and descent stage during Martian atmospheric entry. This is the "7 minutes of terror" maneuver made famous by the successful landing of the Curiosity rover in 2012.

Whether they are working on final assembly of the vehicle at Kennedy Space Center, testing software and subsystems at JPL, or (as the majority of the team is doing) teleworking due to coronavirus safety precautions, the Perseverance team remains on track to meet the opening of the rover's launch period. No matter what day Perseverance launches, it will land at Mars' Jezero Crater on Feb. 18, 2021.
The Perseverance rover's astrobiology mission will search for signs of ancient microbial life. It will also characterize the planet's climate and geology, collect samples for future return to Earth, and pave the way for human exploration of the Red Planet.

The rover will feature many new technology innovations, including the most advanced pair of "eyes" ever sent to the Red Planet's surface. The Mastcam-Z instrument packs a next-gen zoom capability that will help the mission make 3D imagery more easily.
The mission will also include NASA's small Mars Helicopter (called Ingenuity), the first aircraft to attempt powered flight on another planet. The helicopter will ride to Mars attached to the belly of the Perseverance rover. For several months following the rover's landing, Ingenuity will remain encapsulated in a protective cover to shield it from debris during entry, descent, and landing. When the timing in the rover mission is right, Ingenuity will be deployed to stand and operate on its own on the surface of the Red Planet.
If the 4-lb (1.81-kg), solar-powered craft -- a combination of specially designed components and off-the-shelf parts -- survives the cold Martian nights during its pre-flight checkout, the team will proceed with testing. If successful during its 30-Martian-day (31-Earth-day) experimental flight test window, the small craft will prove that powered flight can be achieved on Mars.

The Perseverance rover mission is part of a larger program that includes missions to the Moon as a way to prepare for human exploration of the Red Planet. Charged with returning astronauts to the Moon by 2024, NASA aims to establish a sustained human presence on and around the Moon by 2028 through NASA's Artemis lunar exploration plans.
