New ‘KEM’ proposal would extend New Horizons post-Pluto mission to 2021

If approved by NASA, the KEM proposal will allow New Horizons to continue its study of the outer fringes of the Solar System until 2021, including a flyby of 2014 MU69. Image Credit: NASA/JHUAPL/SwRI

The New Horizons mission has revolutionized our understanding of Pluto and its moons, after conducting the first-ever flyby last summer. These mysterious worlds were finally seen up close, and this new view created as many, if not more, new questions as it answered old ones. While the flyby may be long over now, the spacecraft itself is still in excellent health and continues to plunge deeper into the Kuiper Belt at the outer fringes of the Solar System. Scientists have been eager for New Horizons to continue exploring this region farther out past Pluto, and now a proposal has been formally submitted to NASA to do just that. This extended mission will conduct a flyby of at least one more Kuiper Belt Object (KBO) and last until 2021.

NASA’s next Mars rover is due to launch in July or August 2020, and the number of potential landing sites has now been narrowed down by scientists to eight locations. Out of an initial list of 21 targets, eight sites have been chosen as candidate landing sites for the Mars 2020 Rover. Due to land on Mars in February 2021, the rover will search for rocks which could hold possible evidence of past life on the planet.

New study traces dark near-Earth asteroids back to oddball asteroid family

Near-Earth asteroids, also known as Near Earth Objects (NEOs), are some of the best studied space rocks in the Solar System, primarily due to the fact that they approach the orbit of Earth, making them potentially dangerous to our home planet. Now, a new study has provided evidence that at least some of them, including dark ones which are more difficult to see, originate from the oddball Euphrosyne family of dark asteroids which are at the outer edge of the main asteroid belt between Mars and Jupiter, but have highly inclined orbits well above the plane or “equator” of the Solar System.

NASA awards grants to Ozark IC to create circuits for proposed Venus rover

In what may be a significant step toward the seemingly far-off goal of sending a rover to the surface of Venus, NASA has awarded two grants totalling $245,000 to a semiconductor technology firm to design complex integrated circuits which could withstand the extremely harsh environment on this neighboring world.

‘Ocean Worlds Exploration Program’: new budget proposal calls for missions to Europa, Enceladus and Titan

The exploration of the outer Solar System has revealed a plethora of amazing worlds, the likes of which were little known or even unheard of just a decade ago. Among the most remarkable and tantalizing discoveries are the “ocean moons” such as Europa and Enceladus, which have oceans or seas of liquid water beneath their icy surfaces. Other moons like Titan, Ganymede, and Callisto may also have them, and even some asteroids. Titan also has seas and lakes of liquid methane/ethane on its surface. With all that water, these small worlds have become a primary focus in the search for possible life elsewhere in the Solar System. Now, a new NASA budget proposal wants to take that a step further and fund new missions to these watery moons.
