InSight has gone two for two, placing the second of its instruments gently on the Martian ground. The Heat Flow and Physical Properties Probe (HP3, pronounced "H-P-cubed") is on the ground next to the seismometer. It was placed at about 10:39 local solar time on InSight's sol 76 (today, 12 February). This is great news! Now it's time to bury the "mole" in the ground. I plan to have a more detailed update on the progress of the mission next week. In the meantime, you can check in on InSight through its raw images page here.
