Last week, NASA shared a blog post saying they detected a sensor glitch associated with the James Webb Space Telescope's Mid-Infrared Instrument (MIRI). For some reason, the sensor for MIRI's Medium Resolution Spectroscopy (MRS) is receiving less light than expected at the longest wavelengths.

NASA is investigating the cause, and said that the instrument is not at risk and no effect has been seen for images taken by MIRI. According to agency officials, all other modes of JWST and MIRI remain unaffected, and they are searching for the underlying issue.

The glitch was found this month during regular calibration and monitoring of the telescope's performance.

It was an exciting time when, two weeks ago, SpaceX got the clearance it needed to conduct its first orbital flight test with the Starship and Super Heavy launch system. After years of waiting, SN flight tests, static fire tests, and stacking and unstacking, the long-awaited test of the SN24 Starship and BN7 Booster prototype was on. For this flight, SpaceX hoped to achieve an altitude of at least 150 km (90 mi) above sea level, crossing the 100 km (62 mi) threshold that officially marks the boundary of "space" (aka. the Karman Line) and making a partial transit around the world before splashing down off the coast of Hawaii.

Unfortunately, things began to go awry a few minutes into the flight as the Starship prototype failed to separate from the booster, sending the rocket into a spin that ended in an explosion.

One of the world's most powerful radio telescope arrays is joining the hunt for signals from other galactic civilizations. The National Science Foundation's Karl G. Jansky Very Large Array (VLA), situated about 50 miles west of Socorro, New Mexico, is collecting data that scientists will analyze for the type of emissions that only artificial transmitters make, signals that would betray the existence of a technically accomplished society.

"The VLA is the go-to instrument for radio astronomers, but this is the first time we are using it in a wide-ranging and continuous search for technosignatures," said Andrew Siemion, Bernard M. Oliver Chair for SETI at the SETI Institute.

The VLA is one of the most productive radio telescopes in the world and consists of 27 antennas spread over 23 miles of desert real estate. Since 2017, it has been engaged in a project known as VLASS (Very Large Array Sky Survey), a radio reconnaissance of 80% of the sky.

Wildlife and environmental groups sued the Federal Aviation Administration on Monday over SpaceX's launch last month of its giant rocket from Texas.
