In mid-August, the spacecraft will perform a burn to bring it into a circular orbit of 50km above the lunar surface. This will give LROC a resolution of 50cm per pixel.
"To perform a burn " is a technical jargon, but what does it mean?
It means to use its engine for a time to change its speed. Most of the time spacecrafts coast without using their engines.
That's right. Chemical engines, rockets, they have be ignited, they burn.
