Wrong as usual, if you make a big deal about the American use of Russian RD180 then the below is actually more embarrassing for the Chinese.
Austrian Academy of Sciences contributed flight telemetry instruments and software for the rover landing. Institut de Recherche en Astrophysique et Planétologie in France contributed a Laser-Induced Breakdown Spectroscopy instrument on the Tianwen 1 rover. CNES, provided guidance to their Chinese counterparts on the spectroscopy technique, which uses a laser to zap a pinhead-size portion of a rock, and a spectrometer to analyze the light given off by plasma generated by the laser’s interaction with the rock’s surface. The technique allows an instrument to determine the chemical make-up of rocks on Mars.
LOL such overdramatization over a little collaboration.
Meanhwile,
Austria contributed in main camera on the Nasa's mars rover, Mastcam-Z ,used for flight calibration.
Denmark's Niels Bohr Institute for Astronomy, Physics, and Geophysics provided the permanent magnet arrays for the Athena Payload on NASA’s rover
The optical and electronic elements at the top of its mast of the five instruments ,make up
SuperCam,contributed by France.
Spain contributed in the Mars Environmental Dynamics Analyzer is known as MEDA. It makes weather measurements including wind speed and direction, temperature and humidity, and also measures the amount and size of dust particles in the Martian atmosphere.
The Radar Imager for Perseverance known as RIMFAX,is contributed by Norway.
NASA's sky crane tech used in rover landing was developed with Germany,France contribution.
Italy built the micro-reflector which gives an accurate location of the Rover Perseverance.The apparatus connects with the satellites that orbit around Mars.
Netherlands contributed in parachuting tech used in the rover for landing which involved slowing the 1,025-kg-spacecraft from 1,235 km/h to just 320 km/h. It did this within approximately two minutes.
Australia contributed on PIXL of the rover ;the Queensland University of Technology (QUT) have built software to fast process the data as it comes down from Mars.
These are just some of the key instruments;navigation and guidance also involves contribution by a plethora of nations.
Whatever contribution CNSA is getting is Peebles compared to that amassed by NASA.
Bangladesh should follow the South Korean model of development or adjust it for it's own development if it really wants to become a developed nation.
South Korea started poorer than East Pakistan aka Bangladesh I think but now look at them , but again Bangladeshis not only need a good leader but people in general need to be nationalistic.
Taiwan, Singapore and South Korea etc started off very poor in the beginning but became more developed due to it's people/culture
Even Vietnam is doing better than Bangladesh , culture plays a great role in development
Also replace Bangladeshi with Koreans,than maybe. Culture and genetics works hand in hand,culture is complementary of and the byproduct for character shown by a civilization's genetic traits. Like u can't expect an america pitbull terrier to have the temperament of a border collie.
