Write a comment
A Chinese high-thrust oxyhydrogen engine designed for the Long March-5 carrier rocket has completed a 520-second test in Beijing in preparation for space station missions, the engine's maker said on Wednesday.
Developed by an institute under the China Aerospace Science and Technology Corporation (CASC), the engine is the most advanced cryogenic liquid rocket engine that has been put into u ISS Leaks May Be Caused by Metal Fatigue, Micrometeorite Impact, Source Says

A commission of Russian State Space Corporation Roscosmos believes that cracks in Russia's Zvezda module at the International Space Station (ISS) were most likely formed due to metal fatigue or micrometeorite impact, a source in the rocket and space sphere said on Wednesday.

The China National Space Administration made public on Thursday morning the first high-definition pictures of Mars taken by the nation's spacecraft.
The pictures - two black-and-white and one color - were shot recently by China's Tianwen 1 robotic probe when the spacecraft was travelling in Mars orbit, according to the administration.

The planet Mars has no global magnetic field, although scientists believe it did have one at some point in the past. Previous studies suggest that when Mars' global magnetic field was present, it was approximately the same strength as Earth's current field.
Surprisingly, instruments from past Mars missions, both orbiters and landers, have spotted patches on the planet's surface that are st China's commercial rocket SD-3 to make maiden flight in 2022

Smart Dragon-3 (SD-3), the third member of China's Dragon series commercial carrier rockets family, will make its maiden flight in 2022, its developer said Wednesday.
A four-stage solid-propellant rocket, the SD-3 will be the largest and have the highest carrying capacity among the Dragon series, according to the China Academy of Launch Vehicle Technology.

Write a comment
Engineers have successfully repaired a liquid oxygen valve on the Space Launch System rocket's core stage with subsequent checks confirming the valve to be operating properly.
The team plans to power up the core stage for remaining functional checks later this week before moving forward with final preparations for a hot fire test in mid-March at NASA's Stennis Space Center near Bay St. Lou NASA prepares Dragon capsule for first reuse with astronauts

NASA is preparing for the first time to reuse a SpaceX Dragon capsule, the Endeavor, on a crewed mission in April.
The capsule previously took astronauts Bob Behnken and Doug Hurley to the International Space Station in May. The upcoming Crew 2 mission is planned for launch no earlier than April 20 from Kennedy Space Center.
NASA gave a detailed update this week about the capsule's r SpaceX Starship makes upright landing, but rocket explodes minutes later

Elon Musk's SpaceX notched the first upright landing of the company's deep-space Starship rocket after a test flight early Wednesday evening in Boca Chica, Texas - but the rocket exploded minutes later.
A live feed showed the stainless steel rocket soaring above the South Texas shoreline, flipping over and decelerating to a gentle touchdown at a slight angle on the landing pad.

Why does ESA send missions beyond our Earth? To explore unknown worlds, and better understand our place in the Universe. But that answer only gives part of the picture. The first thing people do when they first reach space is to turn back to see our homeworld. Looking down on our planet from above allows ESA with its global partners to monitor climate, disasters and environmental changes – to work together to protect our home.
And danger comes from above as well as below: a close eye on our stormy Sun is vital to gather early warning of
Help is a long way away: The challenges of sending humans to Mars

On July 20, 1969, Apollo 11 astronaut Buzz Aldrin stepped out a lunar lander onto the surface of the moon. The landscape in front of him, which was made up of stark blacks and grays, resembled what he later called "magnificent desolation."
When it comes to desolation, however, the moon may have nothing on Mars.
The red planet circles the sun at an average distance of about 140 million miles from Earth. When people eventually visit this world—whether that's in 20 years or 50—they may face a journey lasting 1,000 days or longer. The entire Apollo 11 mission, in contrast, lasted just a little over eight days. If future Mars astronauts get lonely, or if something more serious goes wrong, help is a long way away.
For researchers who study how human bodies and minds respond to the rigors of space travel, the scenario poses a lot of unknowns.
