Helium payload
WebPayloads cannot exceed a package weight/size ratio of three ounces per square inch. No payload package can exceed 6 pounds in weight. The entire weight of the payload, excluding the balloon, cannot exceed 12 pounds. No rope or cable should be used which requires more than 50 pounds of force to separate the; payload packages from the balloon. WebCredit: Columbia Scientific Balloon Facility Large unmanned helium balloons provide NASA with an inexpensive means to place payloads into a space environment. The unique capabilities of this program are crucial for the development of new technologies and payloads for NASA's space flight missions.

WebHelium is een kleurloos en reukloos edelgas en heeft een extreem laag kookpunt (4,2 K ), het laagste van alle elementen. Het is in de meeste omstandigheden chemisch inert. Het is na waterstof het meest voorkomende element in het universum. Helium bestaat uit losse … WebYes, a helium balloon can certainly work on Mars. There have been many studies at NASA's Jet Propulsion Laboratory and NASA's Wallops Flight Facility that show feasible mission designs. Solar-heated Montgolfier balloons may provide more lift for the same total system mass, but have very large altitude variations, usually touching down at night.
