## FAQs
### Q: When was the Hope probe launched and when did it arrive at Mars?
A: The Hope probe launched on July 19, 2020, and successfully entered orbit around Mars on February 9, 2021.

### Q: Who built and operates the Hope probe?
A: The probe was manufactured by the Mohammed bin Rashid Space Centre, the Laboratory for Atmospheric and Space Physics, the University of California, Berkeley, and Arizona State University. It is operated by the Mohammed bin Rashid Space Centre.

### Q: What is the orbit of the Hope probe around Mars?
A: The probe has a highly elliptical orbit with a periapsis (closest point) of 20,000 km and an apoapsis (farthest point) of 43,000 km. It completes one orbit approximately every 55 hours.

## Why It Matters
The Emirates Mars Mission (Hope) represents a landmark achievement in space exploration, signifying the first interplanetary mission undertaken by an Arab nation. It moves beyond the traditional focus on Mars' surface to provide a holistic, global view of the Martian atmosphere. The mission's unique scientific orbit allows it to sample the atmosphere at various times of day and across different seasons, enabling scientists to study atmospheric dynamics, including the escape of hydrogen and oxygen into space, which provides clues to the planet's past habitability.

The project is also notable for its collaborative model, partnering the Mohammed bin Rashid Space Centre in the UAE with three U.S.-based institutions: Arizona State University, the University of California, Berkeley, and the Laboratory for Atmospheric and Space Physics. This partnership facilitated a significant knowledge transfer, building capabilities within the UAE's space sector. By openly sharing its data globally, the mission serves as a tool for scientific diplomacy and contributes valuable new data to the global understanding of Mars.

## Notable For
- **First Arab Interplanetary Mission:** It is the first spacecraft from an Arab nation to reach Mars orbit.
- **Unique Scientific Orbit:** Its 55-hour, highly elliptical orbit (20,000 km x 43,000 km) enables a global, diurnal view of the Martian atmosphere, unlike most other orbiters which are in lower, polar orbits.
- **Atmospheric Science Focus:** The mission's primary goal is to create the first holistic picture of the Martian atmosphere, studying daily and seasonal weather cycles.
- **International Collaboration:** The probe was a joint effort between the UAE's Mohammed bin Rashid Space Centre and U.S. institutions including Arizona State University and the University of California, Berkeley.

## Body
### Mission Specifications and Launch
The Emirates Mars Mission, known as the "Hope" probe (Arabic: مسبار الأمل), is a robotic space exploration mission launched on July 19, 2020, at 21:58:14 UTC. It was launched aboard a Japanese H-IIA rocket from the Tanegashima Space Center. The launch services were provided by Mitsubishi Heavy Industries. The probe's takeoff mass was 1,350 kg, with a dry mass of 550 kg. It has a nominal power output of 1,800 Watts.

### Orbital Operations and Objectives
Upon reaching Mars, the probe entered a highly elliptical orbit to begin its scientific mission. This orbit is characterized by a periapsis of 20,000 kilometres and an apoapsis of 43,000 kilometres. The spacecraft completes one full orbit every 55 hours. This specific orbital path was chosen to allow the probe's instruments to observe the planet's atmosphere across different times of day and seasons, building a comprehensive model of Martian weather and climate.

### Development and Partners
The mission is operated by the Mohammed bin Rashid Space Centre (MBRSC) in the UAE. The probe was manufactured through a partnership involving MBRSC, the Laboratory for Atmospheric and Space Physics (LASP), the University of California, Berkeley, and Arizona State University. Arizona State University is a public research university located in Tempe, Arizona, founded in 1885. The H-IIA launch vehicle used for the mission is a Japanese medium-lift expendable rocket. The mission maintains an active online presence, with its official Twitter account (@HopeMarsMission) having accrued over 55,000 followers as of early 2023.

### Data and Identifiers
The mission is cataloged in international databases with the COSPAR ID 2020-047A and the NAIF ID -62. The public can access more information about the mission through its official websites (emiratesmarsmission.ae) and its Wikimedia Commons category "Emirates Mars missions."
