Elon Musk says his company SpaceX is the largest satellite operator in the world. It has grown its workforce significantly over the past few years

SpaceX and other companies are rushing to put thousands of small, inexpensive satellites in orbit, but pressure to keep costs low and a lack of regulation leave those satellites vulnerable to hackers.

The one-tonne robot wiggles its wheels before rolling forwards across Jezero Crater's dusty terrain.

Mars-bound craft landed at an angle and appeared to leak fuel

‘Until now, it was uncertain that space plasma hurricanes even existed, so to prove this with such a striking observation is incredible’, scientist says

The first human expedition to Mars could take place within five to ten years. The crew will be made up mainly of volunteers, with the goal of establishing a colony on the red planet and eventually making the trip to Mars available to anyone.

Yusaku Maezawa announced he will choose eight members of the public to join him on a trip around the moon, scheduled to fly on SpaceX's Starship in 2023.

Amazing images as Nasa's Perseverance rover lands on Mars and seeks signs of past microbial life.

Earth is the only planet in the solar system with aircraft capable of sustained flight. Suppose the ground-breaking Ingenuity helicopter, currently stowed aboard the similarly spectacular Mars Perseverance rover, accomplishes its planned mission. In that case, Mars will become the second planet to have a powered aircraft fly through its atmosphere.  Ingenuity has sent its … Continue reading "The Mars Helicopter is Online and Getting Ready to Fly"

NASA's Mars Perseverance rover acquired this image using its Right Mastcam-Z camera. Mastcam-Z is a pair of cameras located high on the rover's mast. This image was acquired on Feb. 24, 2021 (Sol 3) at the local mean solar time of 16:22:38.

When NASA's Perseverance rover touched down on the Martian surface last week, humans cheered from the confines of planet Earth. But if the space agency or others hope to leave and send astronauts to Mars, experts say they need to consider a technology that was studied decades ago but never fully developed: nuclear-powered rockets.

Engineers hinted they had hidden a code in the parachute that landed the Perseverance rover. Within hours, puzzle enthusiasts cracked it.

Just four martian days after touching down on the Red Planet, NASA’s Perseverance rover has sent back its first video of its new home: a 1-minute arabesque of color and motion captured from four on-board cameras, as the car-size rover dangles from its rocket-propelled descent vehicle, a red-and-white parachute snaps into place, and the pitted surface of Mars comes slowly into view, dark canyons giving way to ripples of dust that look like giant, rust-colored dunes (see video, above).

NASA released stunning new video for the first time Monday from its Perseverance rover's audacious landing on Mars last week. The footage, shot from multiple cameras, captures the rover's entry, descent and landing on the red planet's Jezero Crater on Feb. 18.

The new planetoid unseats Farout, which held the title for about two years

Black holes are regions in space where gravity is very strong—so strong that nothing that enters them can escape, including light. Theoretical predictions suggest that there is a radius surrounding black holes known as the event horizon. Once something passes the event horizon, it can no longer escape a black hole, as gravity becomes stronger as it approaches its center.

If all goes well, the first flight on Mars will be made by Perseverance Mars rover's companion drone helicopter, the Linux-powered Ingenuity.

The first black hole that humanity ever discovered is much more massive than previously thought, according to new research. The galactic X-ray source, later named Cygnus X-1, was discovered in 1965, when a pair of Geiger counters were carried on board a sub-orbital rocket launched from New Mexico.

Perseverance landed safely on the red planet on Thursday, immediately getting to work with a first photo of the rover's "forever home."

The spacecraft will arrive at Mars on February 18, joining missions from China and the United Arab Emirates.
