During the Mars landing, a number of hardware elements slowed the spacecraft’s speed from 20,000 kph, when it first entered the Martian atmosphere, to zero miles per hour when placed gently on its surface.

Reporting from Space, Tuesday (9/8/2022) all processes from entering the atmosphere to NASA’s Perseverance landing on the surface of Mars, occurred in just a very short time, for seven minutes.

Once the job is done, hardware such as parachutes, heat shields, and more are removed from NASA’s Mars rover Perseverance, hitting Planet Mars some distance away so as not to damage it.

For the past year and a half, the Perseverance team has been looking at and cataloging the suspected EDL debris. The Perseverance rover landing wreckage shots turned out to be quite a lot.

This extreme weather potential is the result of the detection of tropical cyclone seeds 97W, which can affect weather conditions in Indonesia.

Based on BMKG analysis, tropical cyclone seeds 97W were observed in the South China Sea west of the Philippines, to be precise at around 14.0 North Latitude 112.6 East Longitude with a maximum wind speed of 20 knots and a minimum air pressure of 1003.7 mb.

The Deputy for Meteorology at BMKG, Guswanto, said that this system is moving in a west-northwest direction with the potential to grow into a tropical cyclone in the next 24 hours in the medium category.

According to him, the seeds of the tropical cyclone induce an increase in wind speed of more than 25 knots (low level jet) in the South China Sea.

The cyclonic circulation was observed in the Pacific Ocean north of West Papua which forms a meeting area and wind deceleration (convergence), which extends in the Pacific Ocean north of Halmahera to the north of West Papua.
