Spaceships getting damaged or crashing is common story in science fiction but it’s also terrifyingly common with real spaceships. So what do we if our spaceship gets damaged?

Mr. Musk, who runs Tesla and SpaceX, visited Twitter’s San Francisco headquarters on Wednesday and tweeted a nine-second video of himself smiling and carrying a porcelain sink into the building.

“Entering Twitter HQ — let that sink in!” he wrote.

The world’s richest man arrived at Twitter’s San Francisco offices on Wednesday ahead of a Friday deadline to complete the acquisition of the social media service.

Just to return the emphasis to ‘out there’.

Upcoming launches and landings of crew members to and from the International Space Station, and launches of rockets delivering spacecraft that observe the Earth, visit other planets and explore the universe.

The world’s most powerful operational rocket could finally launch again as soon as next week.

SpaceX’s Falcon Heavy, the most powerful rocket in the world, is approaching its first launch in over three years. The massive launch system, which is powered by three modified Falcon 9 first-stage boosters, is now linked together and awaiting launch from Pad 39A at NASA’s Kennedy Space Center.

Ahead of the launch, SpaceX has shared an image of the behemoth’s 27 Merlin engines on Twitter. “Falcon Heavy in the hangar at Launch Complex 39A,” the company wrote alongside the impressive photo.

On October 17th, a NASA official speaking at an Astrophysics Advisory Committee meeting revealed that the European Space Agency (ESA) had begun “exploring options” and studying the feasibility of launching the Euclid near-infrared space telescope on SpaceX’s Falcon 9 rocket.

In a major upset, director Josef Aschbacher confirmed less than three days later that ESA will contract with SpaceX to launch the Euclid telescope and Hera, a multi-spacecraft mission to a near-Earth asteroid, after all domestic alternatives fell through.

The European Union and, by proxy, ESA, are infamously insular and parochial about rocket launch services. That attitude was largely cultivated by ESA and the French company Arianespace’s success in the international commercial launch market in the 1980s, 1990s, and 2000s – a hard-fought position that all parties eventually seemed to take for granted. When that golden era slammed headfirst into the brick wall erected by SpaceX in the mid-2010s, Arianespace found itself facing a truly threatening competitor for the first time in 15+ years.

Physicists have been chasing antimatter technology for more than 80 years now — driven by the promise of oppositely oriented particles that explode in a burst of energy whenever they make contact with their more common counterpart. If we could tame antimatter, those explosions could be used to power a new generation of technology, from molecular scanners to rocket engines to the so-called “annihilation laser,” a tightly concentrated energy beam fueled by annihilating positrons. But while scientists have seen recent breakthroughs in creating the particles, they still have trouble capturing and containing them.
