Lebanon, Kenya and Jamaica are among the handful of countries that have gotten rid of the ‘period tax’ - the additional charge the government adds to the retail price of sanitary products like pads or tampons. Now, a new campaign has started to scrap the tax in Pakistan. According to UNICEF, the tax can add up to 40% to the retail price of sanitary pads in the country, making them out of reach for many women and girls, especially in impoverished communities.

Mahnoor Omer, the 25-year-old lawyer from Pakistan who has started a legal case to cut the tax, talks us through attitudes to periods in her home country and explains why this campaign is so important to her. And we hear from young women in Pakistan who tell us what they think of the tax.

For the first time in more than 50 years, NASA is taking humanity back to the moon with its Artemis II mission. The crew is made up of four astronauts, including the first woman astronaut and the first black astronaut to travel to the moon. They will blast off from the Kennedy Space Center in Florida, in a spacecraft never used by humans before, and begin their journey to orbit around the moon.

The launch is expected to happen on 1 April - but NASA are keeping their options open, and have named six other potential dates. So - when will the launch take place? And once it does, how long will it take the mission to reach the Moon?
