Iran simultaneously launches three satellites - state media

Iran simultaneously launched three satellites for the first time on Sunday using the Simorgh (Phoenix) satellite carrier rocket developed by the Ministry of Defence, state media reported. One satellite weighing 32 kg (70 pounds) and two nano-satellites of less than 10 kg each were sent to a minimum orbit of 450 km (280 miles), with the two smaller devices aimed at testing narrowband communication and geopositioning technology, the reports said.

Mars rover data confirms ancient lake sediments on red planet

NASA's rover Perseverance has gathered data confirming the existence of ancient lake sediments deposited by water that once filled a giant basin on Mars called Jerezo Crater, according to a study published on Friday. The findings from ground-penetrating radar observations conducted by the robotic rover substantiate previous orbital imagery and other data leading scientists to theorize that portions of Mars were once covered in water and may have harbored microbial life.
