Super Pressure Balloon Launched by NASA from New Zealand [ Current Affairs ]
A super pressure balloon has been launched by National Aeronautics and Space Administration (NASA) successfully to conduct near-space scientific investigations from South Island Wanaka Airport, New Zealand in the fifth attempt.
- Due to bad weather previous four attempts was get the massive balloon airborne were thwarted.
- The balloon is 532, 000 cubic meters and seeks to continue airborne for more than 100 days.
- It is predicted to circumnavigate the globe in the mid-latitudes of southern hemisphere once every one to three weeks, based on wind speeds in the stratosphere.
- Operational float altitude of balloon is 33.5 kms.
- It will be observable from the ground, mainly at sunrise and sunset in the southern mid-latitudes of hemisphere.
- Its aircraft operations through the mission will be measured by NASA’s balloon specialists at Columbia Scientific Balloon Facility and NASA’s Wallops Flight Facility, Virginia.
- Long-duration balloon air travel at continuous altitudes play and significant role in providing cheap access to the near-space environment for science and technology.
About Super pressure balloon
A super pressure balloon is an aerostatic balloon whose volume kept moderately constant in the face of changes in the temperature of the controlled lifting gas.
- So from this balloon are allowed to keep a stable altitude for long periods.
- This is in difference with much more mutual variable-volume balloons, which are moreover only partly filled with lifting gas, or made with more flexible materials.
