What phase do sister chromatids move apart?

I remember the stages of mitosis through IPMATC
Interphase - the cell just does cell stuff, and the chromosomes start to condense.
Metaphase - the chromosomes meet along the equatorial plane (meet and Metaphase start with the letter 'm'), and the nuclear envelope starts to disintegrate
Anaphase - the chromosome move away from each other (Anaphase and away both start with 'a')
Telophase - the nuclear envelope reforms
Cytokinesis - the cell membrane splits, creating 2 daughter cells

The titanic is the answer

The soviet union beat the us to the first successful launch, with the october 4, 1957, orbiting of sputnik 1, and later beat the us to have the first human in earth orbit, yuri gagarin, on april 12, 1961. the "race" peaked with the july 20, 1969, us landing of the first humans on the moon with apollo 11
