India's TakeMe2Space sets sights on 50-kilowatt data center

Indian startup TakeMe2Space maps a stepwise path toward orbital data centers

TakeMe2Space says it is seeking $55 million to pursue a 50-kilowatt orbital data center.
The startup already flew a 2024 technology demonstration that supported onboard AI inferencing.
Its next steps are a six-unit cubesat in October and a four-satellite constellation planned for 2027.
Early target markets include agriculture, insurance, and customers interested in resilient off-world data storage.

Super Typhoon Sinlaku

Super Typhoon Sinlaku became a rare early-season Category 5-equivalent storm

NASA says Sinlaku reached around 280 km/h sustained winds as it neared the Marianas.
The storm is described as one of only a handful of Category 5 typhoons known to occur so early in the year.
Heavy rain began reaching Saipan, Tinian, and Rota on April 14.
Satellite imagery also captured gravity waves generated high above the storm.
