Building a moon base will require extensive resources and infrastructure.
There are vast quantities of water ice on the moon that represents the potential for extraction and use in rocket fuel. But there are no practical reasons to mine this water.
Hubble took pictures of the oldest galaxies it could – seen here – but the James Webb Space Telescope can go back much farther in time.
The James Webb Space Telescope is set to launch into orbit in December 2021. Its mission is to search for the first light to ever shine in the universe.
Potential conflicts in space over resources can be prevented by a commitment to peaceful collaboration.
As the space race is resumed, and expanded to include private corporations, it is more important than ever to lay the groundwork for peaceful collaboration.
A key goal of the Chang'e-5 mission was to find evidence of some of the youngest volcanic eruptions on the Moon.

Did we observe the most distant gamma ray burst yet seen, or was it something closer to home?
Next month, Russia is sending a director and actor to film in space. What does this mean for filmmakers, astronauts, movie fans and the International Space Station?
Astronomers have found a way to estimate the number of stars in the universe.

Scientists have a good estimate on the staggering number of stars in the universe.
Thousands of the satellites orbiting Earth are small – like this cubical satellite seen here being released from the International Space Station.
In the past decade, the number of satellites in orbit has skyrocketed thanks to tiny electronics and cheap launches. The crowded night sky is posing problems for astronomers and astronauts.
The James Webb Space Telescope is the biggest orbital telescope ever built and is scheduled to be launched into space on Dec. 18, 2021.
The largest orbital telescope ever made will allow astronomers to study the atmospheres of alien planets, learn about how stars form in the Milky Way and peer into the farthest reaches of the universe.
It’s important to understand sex and eroticism in space.

As space exploration takes off, it will become increasingly important to study and understand sex, intimacy, desire and pleasure off-Earth.
Four people – none of them trained astronauts – launched into orbit aboard a SpaceX Dragon capsule on Sept. 15, 2021.
The Inspiration4 mission sent four civilians to space for three days. Though still funded by a billionaire, the mission is a step forward in the nascent space tourism industry.
The temperature of the Sun’s surface is about 6,000℃. But higher above the surface, in the atmosphere, it suddenly shoots up to more than a million degrees!

The growth of online and space activity make traditional ideas of national security increasingly outdated.
The universe has a finite age — 13.8 billion years to be exact. So if it had a beginning, why is it so difficult to say for sure whether it will have an end?
Both Jeff Bezos and Richard Branson successfully rode to space on rockets made by their private companies Blue Origin and Virgin Galactic, respectively.

According to a new poll, people across political and demographic lines think the private space race is good for the future but still just an ego trip for the billionaires involved.
Scientists have been studying lunar samples brought back from Apollo missions to understand the geologic history of the Moon.
Without a magnetic field, the Moon’s surface is exposed to solar wind. These could have been depositing resources like water and potential rocket fuel on the Moon’s surface for billions of years.

Later this year I will spend time with former NASA astronaut instructors, before receiving high-G training, crew resource management training and spacesuit training, among other skills.
Gravity feels like it’s pulling everything toward Earth, but why?

Gravity is something every person on Earth intuitively understands: It is what keeps you on the ground. But how come gravity pulls down, rather than pushes up? Einstein came up with the answer.
Now is not the time for rocket men to abandon spaceship Earth.

Billions of galaxies are in the universe, with billions of stars in every galaxy. Could billions of planets be out there too?
