On June 15, 2011, Iran launched the Rasad-1 satellite into orbit around Earth.

Rasad-1 (the name means Observation-1 in Farsi) is an imaging satellite that was sent into a 162-mile orbit by an Iranian Safir rocket. Rasad-1 made about 15 orbits per day, and sent back pictures to Earth.

This was Iran’s third satellite and the second to be launched successfully by an indigenous rocket. This feat raised concerns among those who feared Iran’s intentions concerning its nuclear development program.

29th April

On April 29, 1985, the European Space Agency’s Spacelab launched on the space shuttle Challenger on mission STS-51B. This was the second time the Spacelab went to space and the first time it flew in a fully operational configuration. 

Spacelab pallets had flown to space on three previous shuttle missions, but this was the first time that the entire laboratory was used to conduct research in microgravity. Spacelab provided a platform for five fields of research: astronomy, atmospheric physics, materials science, life science and fluid dynamics. 

The lab was shaped like a cylinder and measured about 23 feet long, or about the length of a short school bus. The pressurized module was housed in the shuttle’s cargo bay. Seven astronauts, two monkeys and 24 rodents launched with Spacelab during STS-51B. After spending a week doing research in space, they landed safely at Edwards Air Force Base.

January 21st 2019

Monday 21st January from about 4 to 6 am

See a total eclipse of the Moon early  morning Monday 21st January from about 4 to 6 am. The Moon will turn red (“Blood Moon”), but no-one knows in advance just what shade of red, as it depends on the amount of dust, dirt and aerosols in our upper atmosphere, through which sunlight passes to reach the Moon.  Eclipse will begin 2:34 am, with totality lasting from 4:40 to 5:11. Here’s hoping for a clear night!
