A Mars aircraft is a vehicle capable of sustaining powered flight in the atmosphere of Mars. So far, the Mars helicopter Ingenuity is the only object to ever fly on Mars, having completed a total of 9 successful flights so far. It made the first powered flight on 19 April 2021, while stationed on the surface of Mars.

Unlike airplanes, helicopters feature spinning wings called blades or rotors on top. As a helicopter’s blades spin, they create a force called lift that allows the helicopter to rise into the air. For example, helicopters can move straight up or down and hover in the air without moving.

First, and most significantly, helicopters need an atmosphere to fly. The blades, or “rotors” of a helicopter must spin fast enough to generate a force called “lift”. But lift can only be generated in the presence of some kind of atmosphere.

Indeed, flying close to the surface of Mars is the equivalent of flying at more than 87,000 feet on Earth, essentially three times the height of Mount Everest, NASA engineers said. The altitude record for a helicopter flight on earth is 41,000 feet.

The vacuum airship could be used as a communication relay for other vehicular probes on Mars thereby overcoming line of sight constraints. If the vacuum airship is damaged, it can land, be repaired, and re-evacuated to resume operation, whereas a balloon would need to have gas pumped back into the vessel.

Nonetheless, a helium filled party balloon on Mars will definitely not float, but will sink with around the same force one rises at on earth. As for a balloon on Mars made to be a balloon on Mars, it definitely could be done. After all, helium is actually 50% more boyant on Mars.

An air-buoyant vacuum vessel (aka a vacuum balloon) would float in air by the same principles as a helium weather balloon or blimp, but be filled with “nothing” (i.e. vacuum) instead of helium. “Nothing” (i.e. vacuum) is more abundant than helium. “Nothing” (i.e. vacuum) is lighter weight than helium.

You need a material strong enough to stand against the air pressure while being light enough to not end up weighing down the craft. Technically, yes it’s possible.

“Vacua Buoyancy Is Provided by a Vacuum Bag Comprising a Vacuum Membrane Film Wrapped Around a Three-Dimensional (3D) Frame to Displace Air, on Which 3D Graphene “Floats” a First Stack of Two-Dimensional Planar Sheets of Six-Member Carbon Atoms Within the Same 3D Space as a Second Stack of Graphene Oriented at a 90- …

Most balloons can be filled with helium or air, simply check the instructions provided or on the product page for details. Some balloons can only be filled with air due to their size (like mini latex and foil balloons), and some balloons are not designed for helium (like balloon garlands).

When anything like a balloon is filled with a gas that is lighter than the air regarding its density, then the balloon will float. Now it is known that the density of hydrogen and helium is lighter than that of air. So, if a balloon is filled with any of these gases, the balloon will float.

Walmart does not offer balloon filling services in all of its stores, corporate customer service representatives and store associates confirmed. Walmart also does not sell pre-filled helium balloons in-store. If your local Walmart does not fill balloons, you can purchase a helium tank at Walmart.

First, fill the water bottle about 1/3 of the way full with white vinegar. Next, put baking soda into the un-inflated balloon, filling it about halfway. Ideally, you’d have a funnel handy for this process but, because I didn’t have one, I made one out of construction paper rolled up, and tape. It did the trick!

The alpha particles that are emitted from the decaying atom bond with loose electrons underground, producing helium atoms. Currently, this natural process is the only method with which helium is produced on Earth. In other words: You cannot make your own helium!

Argon can be used instead of Helium and is preferred for certain types of metal. Helium is used for lots of lighter than air applications and Hydrogen is a suitable replacement for many where the flammable nature of Hydrogen is not an issue.
