An Ecuadoran satellite launched last month could collide with the remains of a Russian rocket in the coming hours, the country's civilian space agency warned Wednesday.

The "Pegaso" (Pegasus) nanosatellite, designed and built in Ecuador, set off aboard an unmanned rocket April 25 from the Jiuquand station in northern China. It is the country's first.

"Alert: possible collision between NEE-01 Pegaso and Russian rocket remains," tweeted the country's civilian space agency, EXA.

"The collision can happen in the coming hours," said its director and Ecuador's first and only astronaut, Ronnie Nader.

Measuring just 10 by 10 by 75 centimeters (four by four by 30 inches), and weighing 1.2 kilograms (2.6 pounds), Pegaso on Thursday transmitted its first live video with audio.

Last month's launch came amid much fanfare, including a live broadcast.

The South American country plans to send a second satellite into space from Russia in July.
