WASP-96 b is a hot gas giant exoplanet that orbits a Sun-like star roughly 1,150 light years away, in the constellation Phoenix. The planet orbits extremely close to its star (less than 1/20th the distance between Earth and the Sun) and completes one orbit in less than 3½ Earth-days.
NIRISS was contributed by the Canadian Space Agency. The instrument was designed and built by Honeywell in collaboration with the Université de Montréal and the National Research Council Canada.
NASA scientists are preparing to paint the most detailed picture to date of the atmosphere of Venus when the aptly named DAVINCI — or Deep Atmosphere Venus Investigation of Noble Gases, Chemistry, and Imaging — mission drops a probe to the planet's surface.
When the 3-foot-wide (0.9 meters) descent sphere of the DAVINCI mission takes its one-way parachute trip to Venus' surface in the early 2030s, it will be carrying the VASI (Venus Atmospheric Structure Investigation) instrument along with five other instruments. VASI will collect data regarding the temperature, pressure and winds of Venus' atmosphere as it makes its hellish descent and enters the planet's crushing lower atmosphere.
"There are actually some big puzzles about the deep atmosphere of Venus," Ralph Lorenz, the science lead for the VASI instrument and a planetary scientist at the Johns Hopkins Applied Physics Laboratory (APL) in Maryland, said in a statement. "We don't have all the pieces of that puzzle and DAVINCI will give us those pieces by measuring the composition at the same time as the pressure and temperature as we get near the surface."
Lufthansa Technik has converted a decommissioned Airbus A320 into a hydrogen field laboratory to test maintenance and ground-based processes in preparation for hydrogen-powered flight.
The project, which is being funded by Hamburg’s Ministry of Economic Affairs and development bank IFB Hamburg, is a partnership among Lufthansa Technik, Hamburg Airport, German aerospace center DLR and the ZAL Center for Applied Aeronautical Research.
Over the coming months, the Lufthansa aircraft, which was operated for 30 years as D-AIQF, is scheduled to be fitted with a series of hydrogen components, including test systems, an internal tank for liquid hydrogen (LH2) and an onboard fuel cell. These will be paired with supporting ground-based hydrogen infrastructure.
The research is expected to include studies of refueling times and processes; best practices to avoid overfilling and waste; prevention of ice build-up on components and surfaces; hydrogen gas leakage and recovery; safety and fire hazards; inerting of stored hydrogen; and training requirements for ground and maintenance personnel.
A digital twin of the A320 will also be created for use in simulating, developing and testing predictive maintenance methods for hydrogen-powered aircraft systems and components.
These preparations are expected to pave the way for the handling and maintenance of hydrogen-powered aircraft, which are anticipated to enter service in the middle of the next decade.
What are they?
The most conservative hypothesis is that these UFOs are built by humans: experimental vehicles under development by the US military or by foreign militaries. In the past, famous UFO sites (e.g., Area 51) have turned out to be test sites for advanced technologies. Some of the “triangular shaped” objects that are capable of rapid accelerations and high speeds do seem remarkably similar to descriptions of hypersonic vehicles that are currently under development by the Army, Navy, Air Force, DARPA and the NSA. The Indian, Chinese and Russian military are all developing their own hypersonic vehicles. DARPA’s HTV-2 had test flights over a decade ago so that the recent appearance of flying triangular shaped objects that can reach high speeds seems consistent with this hypothesis. There is also extensive work on developing drone swarms by many nations (including even Armenia) whose properties match some UFO reports.HGV-2 India's project of hypersonic missile that supposedly be ready for 2035
