November 10, 2014 Science Discovery: What kinds of jobs do astronauts do?
Astronauts have to do many jobs outside their spacecraft. The International Space Station requires many adjustments that can only be done by trained personnel. Robotic equipment is used to put the components of the space station together but much of the construction can only be done by hand. Astronauts also have to make repairs to complicated items such as Hubble Space Telescope and damaged satalites.theyre work can be dangerous because in space there is lack of oxygen which is why they have to wear space helemets. Also the lack of pressure would cause gases in the blood to separate as if it were boiling. Thats why they wear the space suite.
November 16, 2014 Science discovery: What was Back Death?
The Black Death was disease that hit Europe in the Middle Ages killing around 25 million people in 5 years.it was known as the black death because of the dark marks that appeared on the skin of its victims a few days before they died. It was once thought that the Black Death was more likely to have been a hemorrhagic virus similar to Ebola or Lassa Fver.
hemorrhagic-A group of viruses that reproduce by dissolving the internal organs of the victim.
