Once, the energy system used in space missions was very simple. If it is only a short-term task, then the corresponding detection device only needs a built-in battery or can use the built-in solar energy system and the panel to obtain energy. If the equipment performing the task requires a lot of energy, it can use nuclear energy generators or energy fuels. However, as the scope of space missions continues to expand, such as the Moon’s polar craters, comets, and the cold Jupiter satellites, scientists must develop new energy systems.
In order to achieve this goal, NASA has launched a reward project for the development of future advanced energy storage systems for manned and unmanned space missions. Now, it has selected four excellent solutions. They are the Silicon Anode Based Cells for High Specific Energy Systems from Amprius, High Energy Density and Long from California Institute of Technology. -Life Lithium-Sulfur Batteries for Aerospace Applications (High Energy Density and Long Life Li-Sulfur Battery Systems for Aerospace Applications), Advanced High Energy Rechargeable Lithium-Sulfur Batteries from Indiana University (Advanced High Energy Rechargeable Lithium-Sulfur Battery Systems) And Garnet Electrolyte Based Safe, Lithium-Sulfur Energy Storage (garnet electrolyte-based, lithium-sulfur energy storage system) from the University of Maryland, College Park.
It is reported that each program will be divided into three phases.
Phase 1: Use 250,000 U.S. dollars for component testing and analysis for a period of 8 months;
Phase 2: Use 1 million U.S. dollars for engineering research and development for a period of 1 year;
Phase 3: Use $2 million for model development for a period of 18 months.
Michael Gazarik, deputy administrator of the space technology department, said: “The new energy storage technology is critical to our future exploration in deep space—whether our mission is an asteroid, Mars or another planet. This is what we are in this mission-critical technology area. The reason for the investment."
4x4 Winch is a kind of winch which is powered by direct current electricity provided by the vehicle's electrical system and pull the vehicles out of trouble through the cable or synthetic ropes. It is typically mounted to a vehicle's front or rear bumper. Winch electric is one of the necessary tools for off road adventure.

Typical Applications: off-road vehicles, agricultural vehicles, ATV all-terrain vehicles, yachts, fire rescue vehicles, road barrier vehicles and other special vehicles, special vehicles.
Usages:
Plug the winch remote control into the winch. Your
winch should have come with a remote control attached to a long cord. Look for
the plug at the end of the cord and attach it to the corresponding receptacle
on the outside of the winch. Run the remote control cord from the winch to the
driver`s seat and place the remote control in your vehicle
Put on a pair of thick gloves. Never handle a winch cable without gloves on. The cable could cut your hands.
Find something in front of your car to anchor your winch to. A large tree trunk, boulder, or other vehicle is ideal.
Don`t anchor your winch to something small and weak or you risk breaking it.
Try to find an anchor that`s straight in front of your vehicle.
Use the disengage lever to release the winch cable. The disengage lever should be located on the outside of
the winch. The lever should have an option that says [free spool" or
[disengaged." Turn the lever to that option. This will release the cable so
you`re able to manually pull it out from the winch.
Pull the winch cable all the way to the anchor. Don't pull too
much of the cable out or you'll create unnecessary slack. Set the end of the
cable down next to the anchor.
If the winch cable doesn't reach the anchor, look for another anchor that's closer to your vehicle.
Wrap a tree trunk protector around the bottom of the anchor. A tree trunk protector is a thick nylon strap with two loops, one on each end. Wrap the protector around the anchor so the two end loops are facing you. Hold the two end loops in your hand.
If your winch didn`t come with a tree trunk protector, you can order one online or find one at your local hardware store.
Hook a D-shackle through the 2 loops on the protector. A D-shackle is a curved shackle with a large pin that screws in and out of the shackle. Remove the pin from the D-shackle and put the curved part of the D-shackle through both of the loops on the tree trunk protector. Once the loops are on the shackle, reinsert the pin and twist it to tighten it into place.
Hook the winch hook to the D-shackle with the tip facing up. The winch hook is the hook at the end of the winch cable
Turn the disengage lever back to [engaged." You want the lever to be back in the position it started in before you released the winch cable. This will prevent more cable from coming out of the winch.
Use the winch remote to slowly pull the winch cable taut. Press the button on the remote control to start pulling the winch cable back into the winch. This will cause the winch cable to tighten. Stop pressing the button when the cable is taut
