Having spent well over $150 billion on the International Space Station, NASA fears a potential lack of launch vehicles could leave the orbiting platform without a U.S. astronaut and create a potential safety risk.
Such a gap would occur only if a crew had a problem that forced them to leave the space station early, but it would represent a costly "lost opportunity that cannot be regained"

The "red planet" in the evening sky seems more and more within reach, as leading space agencies aspire astronaut missions to Mars in the future. Unlike the 1969 moon landing, these missions are designed for a long-term stay, which poses new challenges for science: In addition to a habitat, for example, the few materials brought from Earth must be used efficiently and sustainably to equip and fee

A tightly choreographed dance between NASA's Deep Space Network and Mars orbiters will keep the agency's Perseverance in touch with Earth during landing and beyond. When NASA's Mars 2020 Perseverance rover touches down with the Ingenuity Mars Helicopter on the Red Planet on Feb. 18, they won't be alone. From orbit, two robotic buddies will be playing a special role in the event by checking in on

NASA, in collaboration with other leading space agencies, aims to send its first human missions to Mars in the early 2030s, while companies like SpaceX may do so even earlier.

Both Earth and Mars currently have oxidising atmospheres, which is why iron-rich materials in daily life develop rust (a common name for iron oxide) during the oxidation reaction of iron and oxygen. The Earth has had an oxidising atmosphere for approximately two and a half billion years, but before that, the atmosphere of this planet was reducing - there was no rust.

A description of gravity compatible with the principles of quantum mechanics has long been a widely pursued goal in physics. Existing theories of this 'quantum gravity' often involve mathematical corrections to Heisenberg's Uncertainty Principle (HUP), which quantifies the inherent limits in the accuracy of any quantum measurement.
