It's impossible to give a definitive answer to "latest" as there are constantly ongoing missions. However, I can tell you about some very recent and notable missions:

* Artemis I: Launched in November 2022, this was an uncrewed test flight of the Space Launch System (SLS) rocket and Orion spacecraft. It successfully completed a journey around the Moon and is considered a major step towards future human missions.

* Psyche Mission: Launched in October 2023, this mission is heading to 16 Psyche, a massive metallic asteroid that could be the exposed core of a protoplanet.

* Europa Clipper: Scheduled to launch in October 2024, this mission will orbit Jupiter's moon Europa, which is considered one of the most promising places in the solar system for finding signs of life.

* James Webb Space Telescope: While not a "mission" in the traditional sense, the James Webb Space Telescope was deployed in December 2021 and has been making incredible scientific discoveries since then.

If you are interested in the latest news on specific missions, I recommend checking the NASA website or following them on social media.
