The comet that killed the dinosaurs
Monday, 15 February 2021 09:32
It was tens of miles wide and 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 goes 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 NASA wants to fly a helicopter on Mars for the first time

More than a century after the first powered flight on Earth, NASA intends to prove it's possible to replicate the feat on another world.
Transported aboard the Mars 2020 spacecraft that arrives at the Red Planet on Thursday, the small Ingenuity helicopter will have several challenges to overcome - the biggest being the rarefied Martian atmosphere, which is just one percent the density of Ea Melting dusty ice may have carved Martian gullies
Monday, 15 February 2021 09:32
By analyzing the occurrences of exposed dusty ice on Mars using data from NASA's Mars Reconnaissance Orbiter, ASU planetary scientists Aditya Khuller and Philip Christensen have found the lowest latitude detection of dusty water ice on Mars.
The melting of this dusty water ice could have led to the formation of gullies that have eroded into rock and ice at these locations and may provide p Tuning in for a precision landing on Mars on Feb 18

On 18 February 2021, NASA will initiate the most precise landing ever attempted on the Red Planet. A spacecraft with the Perseverance rover on board will enter the Martian atmosphere at around 21:38 (CET) at just under 19,500 kilometres per hour. Within seven crucial minutes, the spacecraft will decelerate to zero using its heat shield, parachute and braking thrusters to set the rover - suspende Perseverance rover lands on Mars this week

After a seven-month journey, NASA's Perseverance rover prepares to touch down on Mars on Thursday after first negotiating a risky landing procedure that will mark the start of its multi-year search for signs of ancient microbial life.
The Mars 2020 mission, which set off late from Florida in late July, includes the largest ever vehicle to be dispatched to the Red Planet.
Built at NASA's Tianwen 1 enters Mars' polar orbit
Monday, 15 February 2021 09:32
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 Slingshot Aerospace names Melanie Stricklan CEO and Gets Laser-Focused on Space Initiatives

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.

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 NASA's TESS discovers new worlds in a river of young stars

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 Portugal joins ESA's Boost!

Portugal joins ESA's Boost! SpaceX launches Starlink satellites, but booster landing fails
Monday, 15 February 2021 05:40
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.
Biotech fit for the Red Planet: New method for growing cyanobacteria under Mars-like conditions
Monday, 15 February 2021 05:10
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 atmosphere, at a low total pressure, as their source of carbon and nitrogen.
U.S. Army satellite to bring imagery directly to troops on the ground

WASHINGTON — A Rocket Lab Electron launch vehicle scheduled to fly next month will carry a cubesat that will be used by the U.S. Army to assess the benefits of having dedicated imaging satellites for battlefield surveillance.
Lunar Reconnaissance Orbiter gets an upgrade to capture new perspectives of the moon
Sunday, 14 February 2021 13:23
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.
