Treaties meant to ensure sustainability in space don’t currently regulate private companies, and not every country has signed on to an agreement for sustainable space exploration.

India became the first country to land near the south pole of the Moon, a notoriously difficult achievement that also marks them as the fourth country to land on the Moon.

The Indian spacecraft could lay the ground for future missions with astronauts, and even for lunar bases.

If an astronaut were to die on Mars, neither cremation nor burial would be good options.

While a return to the Moon will allow the U.S. to collaborate with other nations interested in space, this endeavor is also complicated by geopolitical tensions.

Some people incorrectly say the Moon landings didn’t happen. But the evidence – and logic – isn’t on their side.

There’s a limit to the amount of oxygen we can carry with us in space – particularly if we want to do long-haul journeys to the Moon and Mars.

A US-led coalition and China are both planning to establish bases on the Moon. How the two nations will navigate actions on the Moon and how other countries will be involved is still unclear.

With more than 100 lunar missions planned in coming years, space junk near the Moon could become an issue for humanity. No agency tracks lunar space junk, so two astronomers decided to do it themselves.
