Time Magazine's UAE's Mission to Mars Launches Successfully—a First for the Arab World says that the Mars orbiter named Al-Amal (Hope) or Emirates Mars Mission:
...blasted off from the Tanegashima Space Center on a small southern Japanese island aboard a Mitsubishi Heavy Industries’ H-IIA rocket, on time at 6:58 a.m. (2158 GMT Sunday) into the blue sky. Mitsubishi said the probe has been successfully separated from the rocket and is now on its solo journey. The launch had been delayed for five days because of stormy weather.
Question: What was the duration of the launch window this day? Did it first enter a short period of LEO for phasing and/or staging, or did it launch directly into its interplanetary trajectory? How many stages were involved?
