Parker Solar Probe makes another flyby of the sun, solar energy bags a win, and more science stories

NASA/Johns Hopkins APL NASA this week announced the four-person crew that will lead its Artemis III mission in 2027: NASA astronauts Andre Douglas, Frank Rubio and Randy Bresnik along with ESA's Luca Parmitano as the flight's pilot. Plus, the Parker Solar Probe took another trip around the sun, solar energy overtook coal in May, and more. Here's this week's science news.

NASA's Parker Solar Probe made another close pass around the sun this week, getting 3.8 million miles from the surface and reaching a speed of 430,000 mph. This marked its 28th flyby, and matched the speed and distance records the probe first set back in December 2024. It's hit those numbers five times since. The spacecraft began its latest approach on June 3, and transmitted a beacon tone on Thursday to signal to the team that all is well.

The Parker Solar Probe has been studying our star for eight years, incrementally getting closer and closer to the surface. It launched in 2018 and made its first close approach to the sun that fall, when it came within 15 million miles of the sun's surface. For its first flyby, it reached a maximum speed of 213,200 mph. Despite the harsh conditions in the sun's vicinity — the heat shield reaches an estimated 1,700 degrees F when the spacecraft is closest to the sun — the Parker team says the probe still appears to be doing well after all this time. Below the heat shield, the Parker probe is protected by thermal blankets which have kept the temperature of the spacecraft itself consistent during these flybys.
