It is interesting to compare the JWST to the Hubble Telescope.

The following data was taken from the video:
t = 0.0 s, v = 0 km/h
t = 20.0 s, v = 274 km/h
t = 30.0 s, v = 462 km/h (an increase of 188 km/h in 10.0 s)
t =40.0 s, v = 689 km/h (an increase of 227 km/h in 10.0 s)
t = 50.0 s, v = 859 km/h (an increase of 170 km/h in 10.0 s)
What does it say about the acceleration of the rocket?

Apollo 13 – 50th Anniversary of “Houston, we have a problem!”
One of the most eventful of space missions!
An explosion on board on the way to the Moon left the astronauts scrambling to stay alive, and make it back to Earth.
The phrase “Houston, we have a problem!” (not an exact quote from the mission I know) is a popular quotation from the radio communications between the Apollo 13 astronauts and the NASA Mission Control Center, during the Apollo 13 spaceflight, as the astronauts communicated their discovery of the explosion that crippled their flight.
If you don’t know the story, I highly recommend watching the movie Apollo 13 – Not sure if its on Netflix at the moment.

Traffic Cameras
- Do you think average speed cameras are better than regular speed cameras?
- What are the advantages of both types of speed camera?
- Could you think of a better way to regulate the speed of cars on such roads?
