Video: Juno’s countdown to Jupiter

In a pair of mission extensions, NASA has cleared the way for more seismic observations on Mars with the robotic InSight lander and approved plans for the Juno spacecraft to alter its orbit and perform close flybys of Jupiter’s icy moon Europa, Ganymede, and the volcanic moon Io.

Loaded with investigations into chemotherapy drugs with reduced side effects and radiation detectors for homeland security, a plant-growing chamber to promote future food harvesting in space and a technology demonstration for sample-return capsules, a commercial Cygnus cargo vessel will be sent to the International Space Station next week.

The Air Force will launch a second pair of small security probes 22,300 miles above the Earth using a Delta 4 rocket on Friday to alert ground controllers of impending space collisions and monitor potential meddling with U.S. orbiting assets.
