Venus: Nasa announces two new missions

Nasa has announced that it is sending two new missions to Venus in order to examine the planet's atmosphere and geological features.

The missions, which have each been awarded $500m (£352m) in funding, are due to launch between 2028 and 2030.

Nasa administrator Bill Nelson said the missions would offer the "chance to investigate a planet we haven't been to in more than 30 years".

The last US probe to visit the planet was the Magellan orbiter in 1990.

However, other spacecraft - from Europe and Japan - have orbited the planet since then.

The missions were picked following a peer review process and were chosen based on their potential scientific value and the feasibility of their development plans.
