Beijing (XNA) Feb 16, 2021
China's Tianwen 1 robotic probe entered orbit above Mars' polar regions on Monday, moving closer to the red planet, the China National Space Administration said. The spacecraft activated its 3,000-Newton-thrust orbital-control engine at 5 pm to conduct an orbital plane change maneuver to enter polar orbit with a perigee of about 265 kilometers above the red planet, the administration said

India's premier space organisation, which is directly overseen by the PM's office, is one of just six space agencies around the world to boast full launch capabilities, the capacity to carry out extraterrestrial missions, and operate large fleets of artificial satellites. The Indian Space Research Organisation (ISRO), credited with finding evidence of water on the Moon and successful Mars

A new analysis of ceramic chips embedded in meteorites suggests the formation of our solar system was not as quiet and orderly as we once thought. A new study from University of Chicago scientists builds evidence that the baby solar system likely witnessed wild temperature swings and changing conditions-contradicting the decades-old theory that the solar syst

Using observations from NASA's Transiting Exoplanet Survey Satellite (TESS), an international team of astronomers has discovered a trio of hot worlds larger than Earth orbiting a much younger version of our Sun called TOI 451. The system resides in the recently discovered Pisces-Eridanus stream, a collection of stars less than 3% the age of our solar system that stretches across one-third of the

Starlink 19 deployment

WASHINGTON — SpaceX launched another set of Falcon 9 satellites Feb. 15, but suffered a rare failed landing of the rocket’s first stage during the mission.

The Falcon 9 lifted off from Space Launch Complex 40 at Cape Canaveral Space Force Station at 10:59 p.m.

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. Astronauts on Mars will need oxygen, water, food, and other consumables. These will need to be sourced from Mars, because importing them from Earth would be impractical in the long term. In Frontiers in Microbiology, scientists show for the first time that Anabaena cyanobacteria can be grown with only local gases, water, and other nutrients and at low pressure. This makes it much easier to develop sustainable biological life support systems.

"Here we show that cyanobacteria can use gases available in the Martian , at a low total , as their source of carbon and nitrogen.

Lunar Reconnaissance Orbiter gets an upgrade to capture new perspectives of the moon

Eleven years into its mission, the Lunar Reconnaissance Orbiter (LRO) is starting to show its age, but a recent software update promises to give the spacecraft a new lease on life. As NASA's eye in the sky over the moon, the LRO has been responsible for some of the best Lunar observations since the days of Apollo. This new upgrade will allow that legacy to continue.

Launched in June 2009, the LRO quickly succeeded in mapping over 98% of the moon's surface at a resolution of 100 meters per pixel. The orbiter is also famous for taking incredible high-resolution images of the Apollo landing sites, in which landers, rovers, tire tracks and astronaut footprints are clearly visible.

In 2016, the LRO found evidence that the moon is geologically active as a result of tidal forces from the Earth, and also because the moon is shrinking as its core cools.

This image features the southeast wall of a small crater located a few hundred kilometers to the north of the giant Hellas impact basin on Mars. The complete crater itself is about 12 km in diameter; this image shows a 5 x 10 km area.

The Color and Stereo Surface Imaging System (CaSSIS) onboard the ExoMars Trace Gas Orbiter took the image on 19 October 2020.

When viewed with CaSSIS' color filters, the image shows exceptional diversity in color. This diversity is related to the presence of various minerals that reflect light differently at different wavelengths. The light-toned deposits highlight the bedrock exposures of the area, which probably contain ancient clay-rich minerals that would have formed in the presence of water. Also visible are wind-blown sandy deposits that form ripples on the floor of the crater. Their distinctive tan color implies that they contain iron-oxide minerals.

Comet or asteroid: What killed the dinosaurs and where did it come from?

It forever changed history when it crashed into Earth about 66 million years ago.

The Chicxulub impactor, as it's known, left behind a crater off the coast of Mexico that spans 93 miles and runs 12 miles deep. Its devastating impact brought the reign of the dinosaurs to an abrupt and calamitous end by triggering their sudden mass extinction, along with the end of almost three-quarters of the plant and animal species living on Earth.

The enduring puzzle: Where did the asteroid or comet originate, and how did it come to strike Earth? Now, a pair of researchers at the Center for Astrophysics | Harvard & Smithsonian believe they have the answer.

In a study published today in Nature's Scientific Reports, Harvard University astrophysics undergraduate student Amir Siraj and astronomer Avi Loeb put forth a new theory that could explain the origin and journey of this catastrophic object.

SpaceX plans to launch 60 more of its Starlink communications satellites from Florida on Sunday night as the company expands sales of the broadband internet service those satellites provide. Liftoff on a Falcon 9 rocket is scheduled for 11:20 p.m. EST, but the U.S. Space Force forecasts a 60% chance that storm clouds or a threat of lightning that could cause a postponement. Elon

The UAE's "Hope" probe sent back its first image of Mars, the national space agency said Sunday, days after the spacecraft successfully entered the Red Planet's orbit. The picture "captured the largest volcano in the solar system, Olympus Mons, emerging into the early morning sunlight," it said in a statement. The image was taken from an altitude of 24,700 kilometres (15,300 miles) above
