Science News Briefs: SpaceX Delays, Paralympian Astronaut, and Antarctic Concerns

A summary of the latest in science includes SpaceX pausing Falcon 9 launch due to weather, Paralympian John McFall aiming for space, Falcon 9 grounded after landing failure, ISRO anticipates budget rise, Antarctic research highlights climate concerns, and a delay in the Polaris Dawn mission due to equipment issues.

SpaceX has postponed the Falcon 9 launch of Polaris Dawn, originally scheduled for Wednesday, citing unfavorable weather off Florida's coast. The company is also delaying its Crew Dragon capsule launch due to a helium leak.

British Paralympic athlete John McFall will soon become the first individual with a physical disability cleared for ESA space missions. McFall, who won bronze in the 2008 Beijing Paralympics, advocates sports and space progress at the Paris Games.

The U.S. FAA has grounded SpaceX's Falcon 9 after a failed landing during a Starlink mission. The reusable booster fell into the sea post-launch. Meanwhile, ISRO expects a significant budget increase, and Antarctic scientists reveal rapid environmental changes.
