United Arab Emirates (UAE) Mars rover「HOPE」(Al Amal) and Chinese Mars rover“Tianwen 1”However, they were put into orbit around Mars one after another. In July 2020, three Mars probes and rover were launched worldwide, two of which have arrived on Mars.

HOPE, UAE’s first Mars probeTo reduce the speed from 121,000 km / h to 18,000 km / h27 minutes of engine injectionWe entered a temporary orbit (altitude 1000 x 49,380 km) that goes around Mars in 40 hours. It was confirmed that engine injection was started at around 0:48 am on February 10, Japan time, and that the engine was successfully inserted into the orbit at around 1:15 on the same day.
The mission team will make scientific observations of the HOPE orbit in the future.Orbit around Mars in 55 hoursWe plan to change the altitude to (altitude 22,000 x 43,000 km) and start observing the atmosphere of Mars, which is the main purpose. HOPE’s mission isAbout 2 yearsThe plan (687 days, one year on Mars) allows it to be extended for another year.

On the other handChinese Tianwen-1Also started engine injection for orbit insertion at 19:52 local time on February 10, the same as HOPE. Near fire point (one point in the orbit closest to Mars) altitude about 400 km after about 15 minutes,Orbit around Mars in about 10 daysIt has been announced that Tianwen-1 was the first spacecraft in the country to successfully insert into orbit around Mars.
Tianwen-1Consists of an orbiter, a lander, and a roverIt has been.The China National Space Administration (CNSA) will adjust the orbit and observe the planned landing site in the future.Landing is scheduled from May to June 2021It is said.
In addition, on February 19, Japan time, the Mars rover of NASA“Perseverance”Will arrive on Mars and land at Jezero Crater at the western end of the Isidis Plain at around 5:55 am. I am looking forward to the results of the spacecraft and rover that reached Mars at the end of the journey of nearly 500 million km for about 7 months.
