Find out the big approvals and big misses on the budget.
Nasa's budget proposal for 2018 has been released by the space agency revealing what's in store for future missions and what projects could be stalled.
The budget proposes a total fund of $19.1 bn (£14.73bn) for the agency, $561m less than what the agency received in fiscal year 2017. In terms of its missions, Nasa has chosen to prioritise human spaceflight and exploration of the solar system over Earth sciences and educational outreach programmes.
In simple terms, Nasa is pushing for an aggressive space outreach programme where it wants a successful manned mission to anything beyond what humankind has achieved as soon as possible. However, this proposal still needs approval from Congress, so a few programme fundings may be altered. IBTimes UK takes a look at some of the big approvals and some of the misses.
