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.
