In a Wednesday press conference, officials from the United Arab Emirates announced a Mars orbiter mission named Al-Amal (Hope) for the 2020-21 launch opportunity. There's already a strong Twitter presence (official mission handle: https://twitter.com/UAEMarsMission; the science lead has her bilingual account at https://twitter.com/SarahAmiri1). The probe's website is here and it lists an imager, a UV spectrometer, and an infrared spectrometer as instruments, while LASP at CU-Boulder will be the "lead US scientific-academic partner."
More details here, here, and here on the main English-language Emirati news website.
Always good to see more players get in the planetary exploration game, and while Mars is an ambitious first target the UAE appears to have the partners and funding that a new entrant needs.
