Q&A with Jamie Bock, principal investigator of NASA’s SPHEREx mission (members only)

A $150 million cost overrun and two-year launch delay for NASA’s InSight Mars mission could mean fewer opportunities for new planetary science missions in the next few years, but the head of the agency’s science division said this week NASA will still approve development of at least one new solar system probe in December.

Analysis of data from NASA’s planet-hunting Kepler space telescope has revealed a near Earth-size world orbiting in the habitable zone of a sun-like star, scientists announced Thursday, the closest match yet in the ongoing hunt for planets similar in size to Earth where life, as humans understand it, might have a chance to evolve.

In a bit of interplanetary troubleshooting, the robot arm on NASA’s InSight Mars lander has lifted a support structure to reveal an underground thermal probe that got stuck soon after it started hammering into the Red Planet’s surface earlier this year.
