Formålet med bloggen er å bidra til informasjon om luftfart av alle slag. Også litt om ubåter og forsvarsspørsmål. Nyheter vil du finne her også, en del på engelsk som er det mest brukte luftfartsspråket. Har du selv noe som bør komme ut, så send meg en mail til per.gram@hesbynett.no
NASAS MARS-HELIKOPTER MED NOK EN VELLYKKET FLYGNING
Nasas helikopterdrone Ingenuity har gjennomført en tredje flygning, den så langt lengste og raskeste.
Etter to turer der helikopteret har fløyet mindre turer på planetens overflate, dekket det på den tredje turen en distanse på 50 meter. Helikopteret kom også opp i en hastighet på to meter i sekundet.
– Dagens flygning gikk som planlagt, og det var intet annet enn utrolig, sier Dave Lavery, sjefen for Ingenuity-prosjektet.
Droneflygingen på den røde planeten er det første prosjektet i sitt slag. Ingenuity fløy for første gang mandag. Norske Håvard Fjær Grip, som jobber ved Nasa Jet Propulsion Laboratory og California Institute of Technology i Pasadena, er en sentral figur i prosjektet. (NTB)

NASA's Mars
helicopter's third flight goes farther, faster than before
NASA's mini
helicopter Ingenuity on Sunday successfully completed its third flight on
Mars, moving farther and faster than ever before, with a peak speed of 6.6
feet per second.
After two initial
flights during which the craft hovered above the Red Planet's surface, the
helicopter on this third flight covered 64 feet (50 meters) of distance,
reaching the speed of 6.6 feet per second (two meters per second), or four
miles per hour in this latest flight.
"Today's
flight as what we planned for, and yet it was nothing short of
amazing," said Dave Lavery, the Ingenuity project's program executive.
The Perseverance
rover, which carried the four-pound (1.8 kilograms) rotorcraft to Mars,
filmed the 80-second third flight. NASA said Sunday that video clips would
be sent to Earth in the coming days.
The lateral flight
was a test for the helicopter's autonomous navigation system, which
completes the route according to information received beforehand.
"If Ingenuity
flies too fast, the flight algorithm can't track surface features,"
NASA explained in a statement about the flight.
Ingenuity's
flights are challenging because of conditions vastly different from Earth's
-- foremost among them a rarefied atmosphere that has less than one percent
the density of our own.
This means that
Ingenuity's rotors, which span four feet, have to spin at 2,400 revolutions
per minute to achieve lift -- about five times more than a helicopter on
Earth.
NASA announced it
is now preparing for a fourth flight. Each flight is planned to be of
increasing difficulty in order to push Ingenuity to its limits.
The Ingenuity
experiment will end in one month in order to let Perseverance return to its
main task: searching for signs of past microbial life on Mars.
