Science & Tech News: Earth Observation, Jets, Virus, and Moons
This week's news covers a variety of science and technology topics.
A new Earth observation satellite called NISAR, made by NASA and ISRO, is set to launch.
The Indian Air Force is retiring its MiG-21 fighter jets.
There's news about the dangerous Marburg virus, also known as the 'bleeding eye' virus.
We also learn about what comes out of volcanoes, like ash and gases.
