We recently published a list of scientists who are changing the world right now. Of the 50 scientists on our list, a handful of them are deeply committed to space exploration.
These nine scientists are seriously altering the way we view and think about outer space. From first missions to Pluto to lab research and study, this group is moving past physical limits to raise awareness, develop scientific theories, and discover life beyond Earth.
Meet the nine inspiring scientists who are all about space.

Alan Stern is spearheading the most important space mission of 2015.
On July 14, 2015, the NASA spacecraft New Horizons flew by Pluto — closer than any other human-made instrument has ever been. Alan Stern is spearheading the mission, leading the team of scientists that made sure the spacecraft survived its nine-year journey through space.
Until New Horizons reached its closest approach to Pluto, little was known about this dwarf planet and its system of five moons. Now the NASA spacecraft has collected data that Stern and his team will be analyzing over the coming months to understand the geology, composition, and atmospheric content of Pluto in significant detail, something that would never have happened without the New Horizons spacecraft.
Stern is the principal investigator for NASA's New Horizons mission.
Andrea Accomazzo was the first person to land a probe on a comet.
In August 2014, the Rosetta spacecraft began orbiting the comet 67P Churyumov-Gerasimenko and transmitting images to Earth of the dusty space snowball that were more detailed than anything we'd ever seen.
Ultimately, Rosetta will give scientists a better idea of what comets are made of and how they work, as well as provide insights into the chemical makeup of the solar system. As the Rosetta flight director, Andrea Accomazzo helped design the mission and led the team that guided it toward 67P. Now he's working with the European Space Agency on their interplanetary missions to Mercury, Mars, and Jupiter.
Accomazzo is an ESA spacecraft-operations manager at Venus Express and the flight director of the Rosetta mission.
Andrea Pocar took us a step closer to understanding how the sun generates energy.
We all know that the sun is a gigantic nuclear furnace, but until now we didn’t know exactly how it produces energy. To figure it out, scientists have been tracking pp neutrinos — tiny particles released when two protons fuse together deep inside the sun, as lead author Andrea Pocar presented in a recent paper on the Borexino experiment. Through the experiment, scientists are analyzing the elusive particles by blocking out all other noise around a vat of material that emits light when excited by a neutrino.
Because these neutrinos are proof that protons are fusing within the sun, finally observing them helps confirm our theories about how the sun creates energy using fusion — and what's going on inside while that happens.
Pocar is an associate professor in the department of physics at the University of Massachusetts at Amherst.
