š°ļø NASAās New Horizons mission taught us a lot about Pluto, but the spacecraft sped past so quickly.Ā The next step is an orbiter, and now NASA is starting to seriously consider one.
NASA has given theĀ Southwest Research InstituteĀ (SwRI) funding to start developing the idea. SwRI is tasked with investigating āthe important attributes, feasibility and cost of a possible future Pluto orbiter mission.ā
New Horizons visited Pluto before heading deeper into the Kuiper Belt and visiting 2014 MU69, a Kuiper Belt Object (KBO) also known asĀ Ultima Thule. The spacecraft may even visit a third KBO. The proposed Pluto Orbiter would follow a similar path.
Thanks to New Horizons, we know that Pluto is much more complex than we thought. We know that the surface of Pluto is far more active than we couldāve imagined. We know that Pluto has an atmosphere, and we think that Pluto once had liquid on its surface. Pluto may also have aĀ sub-surface ocean, possibly linked to Plutoā so-called heart, theĀ Tombaugh Region.
āThe exploration of Pluto wasnāt easy, but it sure was worth itā, writes Alan Stern,Ā theĀ principal investigatorĀ of theĀ New Horizons.Ā Ā āIt took 14 years (1989 to 2003), about a dozen different mission concept proposals, and the weight of the first National Academy Planetary Science Decadal Survey just to unleash the funding. After a fierce competition among rival teams, NASA ultimately selected New Horizons as its Pluto flyby mission.ā
