  6. made its 4th close approach to the Sun early this morning and set new records in the process! Parker flew about 11.6 million miles from the Sun and achieved a top speed of more than 244,000 mph, breaking records it set in 2018:

    Here's the skinny: My twin went to do a roll to calibrate the onboard magnetometer, overdrew power and tripped software designed to automatically protect the spacecraft. Voyager 2's power state is good and instruments are back on. Resuming science soon.

  8. Our Interstellar Mapping and Acceleration Probe is one step closer to launch! The IMAP mission will study the boundaries of the heliosphere, where material from the Sun meets interstellar space. IMAP is slated to launch in 2024:

    NASA launched a sounding rocket from in Alaska at 8:40 a.m. ET on Jan. 27. The Polar NOx experiment reached 162 miles in altitude and measured the concentration of nitric oxide in the atmosphere above polar regions at night. 🚀🌙

  15. Magnetic storms near Earth can generate dazzling auroras ⬇️ and also release high-energy particles hazardous to spacecraft & astronauts. Our THEMIS mission saw one such event much closer to Earth than previously thought possible. More from :

  16. A planet’s magnetic field plays a big role in how much the host star affects the planet. Here on Earth, we have a robust magnetic field that shields us from solar activity, but not every world is so lucky. More factors to consider in the :
