The AZURE mission successfully launched back-to-back aboard two sounding rockets in Norway tonight. These colorful clouds created a light show in the sky, helping researchers track the flow of neutral and charged particles in Earth's ionosphere.

MMS has spent the last four years touring Earth's magnetosphere, studying its fundamental processes. The four spacecraft rely on high-altitude GPS to pull off their tight flying formations — and these record-breaking fixes may help future missions: go.nasa.gov/2CYvykj pic.twitter.com/UBDInCZc9N

Researchers have found "rain" on the Sun — solar material cascading down magnetic loops — in a place they never expected it. This new discovery could provide a missing link between two of the biggest mysteries in solar science. go.nasa.gov/2Kaq6Rr pic.twitter.com/XWLsQn20yK

🚀 Rocket Report: The sounding rocket team in Norway saw some of the best science conditions yet – strong auroral activity in the sky! Poor weather has kept the two rockets grounded, but clear skies have just arrived. Launch window is open until April 10: go.nasa.gov/2oJGOtz. pic.twitter.com/zp4hA9XFQ7

This Thursday is also a Sun day for #ParkerSolarProbe! ☀️ Today at 6:40pm ET, the mission makes its second close approach to the Sun. The instruments have already been gathering science data for several days as the spacecraft swings by our star. Details: blogs.nasa.gov/parkersolarpro… pic.twitter.com/QybLl3vlCf

45-year-old data has given scientists a fresh look at blobs in the solar wind — bubbles some 50 to 500 times the size of Earth — that could shed light on the processes that send the solar wind out from the Sun. go.nasa.gov/2uMNU2Z pic.twitter.com/Ptij9ZqEtP

Space is a vacuum, but it's not 100% empty. It's filled with particles, energy and magnetic fields — some of which can affect spacecraft and astronauts. Scientists are working to understand the complex factors that shape the space we travel through: science.nasa.gov/science-news/n… pic.twitter.com/ApLhYx6R3u

There aren’t any street signs 🛣 marking the limit of the heliosphere, so the @NASAVoyager team relied on clues from the spacecraft’s instruments to figure out when it crossed into interstellar space. Here’s what it saw on its 11-billion-mile road trip: go.nasa.gov/2YputLr pic.twitter.com/43utz2EXU0

The solar wind — the Sun's outflow of particles and magnetic field — creates a bubble in space that stretches far past the orbit of Neptune. Beyond that bubble is interstellar space. Here are 5️⃣ things to know about the space between the stars. 🌟 go.nasa.gov/2YputLr pic.twitter.com/2tAO2hUxFr

It's #SunDay! ☀️ Yesterday, #ParkerSolarProbe started its second solar encounter, a phase when all of its instruments are collecting and storing science data. The spacecraft will make its closest solar approach for this orbit on April 4. More details: blogs.nasa.gov/parkersolarpro… pic.twitter.com/kvimS3Z2p6

A lot! How electric fields energize and transport particles, how magnetic fields confine them, how rapidly the radiation belts vary and how intense they can get. Researchers will use the information to develop better forecast models, engineers to improve their spacecraft designs.

Not this time! The top speed will be the same as the first orbit. New records for speed and distance to the Sun won't be set until after the next Venus gravity assist in December -- that orbital adjustment is what sends the spacecraft closer to the Sun and to a faster top speed.

As we prepare to travel beyond Earth, we have to understand the weather in space. ⛈🌌 But it's not wind and rain — this "weather" is driven by the Sun's activity and high-energy particles from beyond our solar system.

Just as ancient mariners needed to know about the oceans they traveled, we need to understand the deep-space environment in order to safely travel through it -- and the Voyagers are giving us our first direct observations of interstellar space.
