The agency will be able to do more in the future because of the budget request. NASA deputy administrator Pam Melroy said at a major conference that the $26 billion request is 8 percent more than enacted federal spending levels in the previous fiscal year. The budget would boost the Artemis program.

NASA is aiming for a big 2023 thanks to a generous budget request.

The anniversary of the first spaceflight is marred by the deterioriating relationship between Russia and other countries. Russia's various partnerships shattered in the wake of its Feb. 24 invasion of Ukraine, touching everything from Mars missions to launches on its Russian-built Soyuz rockets, and ongoing threats to withdraw from the ISS program unless newly imposed sanctions are lifted.

The U.S. Space Command spotted a fireball in the sky. According to a study published in the preprint database, the small meteorite had a speed that was far more than the average speed of the other meteorites in the solar system. Some of the data needed to verify their calculations was classified by the U.S. government, so the data was never peer-reviewed or published.

Declassified government data shows that an object exploded over Earth in 2004.

There was a problem with thelium check valve in the mobile launch tower, which necessitated adjustments during a key test ahead of the Artemis 1 launch later this year. The test was resumed on Tuesday with only the core stage tanks. The tanking activity of the upper stage was moved to Thursday.

The Artemis 1 moon mission test was scaled back due to a faulty valve.

The operating temperature of the final instrument was just above absolute zero. There are more steps to be taken to verify the instrument is working well, but this key moment in the commission shows the instrument is theoretically capable of collecting heat-generating signals.

The final James Webb Space Telescope instrument reached super-cold operating temperature.

The Arecibo Observatory was famous for sending a message to E.T. in 1974, but new technologies and the observatory's demise are prompting some researchers to think about a new message to aliens. How this would be transmitted and what message to send are still in the early stages. The hope is that it will be a peaceful message.

Is it time to send another message to aliens? Some scientists think so.
