  For a celestial object that may or may not be a planet, Pluto sure is getting a lot of attention these days.

  Just days after NASA Administrator Jim Bridenstine said that Pluto should be given back its planet status,the U.S. space agency announced that it has funded a study to see if another orbiter mission to the dwarf planet is feasible.

  NASA has provided funding tothe Southwest Research Institute (SwRI) to investigate the costs of the project, its feasibility, as well as develop the spacecraft and payload design requirements and make preliminary cost and risk assessments for new technologies, according to a statement.

  PLUTO SHOULD BE A PLANET AGAIN, RESEARCHERS ARGUE

  Were excited to have this opportunity to inform the decadal survey deliberations with this study, said SwRIs Carly Howett, who is leading the project, in a statement. Our mission concept is to send a single spacecraft to orbit Pluto for two Earth years before breaking away to visit at least one KBO [Kuiper Belt Object] and one other KBO dwarf planet.

  NASA first flew past Pluto in July 2015 with its New Horizons mission, which is managed by SwRI. Throughout that year, the space agency released a series of images of Pluto, includingthe firstclose-up imageof an area near the dwarf planets equator, which contains a range of mountains rising as high as 11,000 feet above Plutos icy surface.

  In January 2019, New Horizons, which was launched in January 2006, flew past fellow Kuiper Beltobject, Ultima Thule.In May, NASA revealed a startling discoverythat there are both water and organic molecules on its surface.

  Alan Stern, SwRIs principal investigator, revealed the organization has been working on its concept for some time.

  In an SwRI-funded study that preceded this new NASA-funded study, we developed a Pluto system orbital tour, showing the mission was possible with planned-capability launch vehicles and existing electric propulsion systems, Stern added in the statement.

  We also showed it is possible to use gravity assists from Plutos largest moon, Charon, to escape Pluto orbit and to go back into the Kuiper Belt for the exploration of more KBOs like MU69 and at least once more dwarf planet for comparison to Pluto.

  Pluto lost its planet status in 2006when it was controversially demoted to dwarf planet by the International Astronomical Union.

  Last month, Bridenstine, during awide-ranging speechat the International Astronautical Congress, said: I am here to tell you, as the NASA Administrator, I believe Pluto should be a planet.

  Bridenstine later responded to a question on his Pluto stance by citing itsburied ocean, its five moons and its multilayered atmosphere. I like there being nineplanets, how about that? he added.
