Elon Musk is dialing back his threat to decommission a capsule used to take astronauts and supplies to the International Space Station for NASA. The threat came as President Donald Trump and Musk argued on social media on Thursday. Trump said he could cut government contracts given to Musk's rocket company, SpaceX. Musk responded by saying SpaceX will begin decommissioning its Dragon spacecraft. It was unclear how serious he was, but he later posted he wouldn't withdraw the capsule. SpaceX is the only U.S. company capable right now of transporting crews to and from the space station, using its four-person Dragon capsules.

A NASA spacecraft will make its second close brush with the sun. The Parker Solar Probe made its record-breaking first pass within 3.8 million miles of the scorching sun in December, flying closer than any object sent before. Parker will attempt the journey again on Saturday. Scientists hope the data from Parker will help them better understand the sun's outer atmosphere and what drives the solar wind. Parker was launched in 2018 to get a close-up look at the sun and is the fastest spacecraft built by humans.
