A Chinese high-thrust oxyhydrogen rocket engine has completed a 520-second test in preparation for the upcoming launches of space station lab modules, its maker said on Wednesday.
Developed by the China Aerospace Science and Technology Corporation, the engine is designed for the core stage of the Long March-5 carrier rocket series, which will be used to launch two lab modules of China's or Sols 3414-3416: Progress!

Over the weekend, we completed the planned drive with a relatively easy (by "Greenheugh Pediment" standards) traverse in the pediment. With lots of bedrock in the workspace, we quickly identified a contact science target for APXS and MAHLI, "Oosta," that was slightly less dusty than the surrounding bedrock and nicely layered.
We decided not to co-target ChemCam LIBS with the contact scienc A Day in the Life of a T-DOC

It takes a team to plan Perseverance's daily activities, including people in many different roles. One of these roles is called the tactical documentarian, or T-DOC. The tactical documentarian takes notes of the decisions made throughout the day as the rover's plan changes, and shares those notes with the team so that the next day's planning team knows what happened, and why.

Our Solar System is believed to have formed from a cloud of gas and dust, the so-called solar nebula, which began to condense on itself gravitationally ~ 4.6 billion years ago. As this cloud contracted, it began to spin and shaped itself into a disk revolving about the highest gravity mass at its centre, which would become our Sun.

The Solar System has eight planets. In 2006, astronomers reclassified Pluto as a dwarf planet, the same class as contains Eris, Sedna, Quaoar, Ceres and perhaps many more solar system small bodies. These are defined approximately as bodies that orbit the Sun but that are not massive enough (unlike regular planets) to gravitationally dominate their environments by clearing away material.

Despite being the closest planet to the Sun, some craters on Mercury's poles contain ice. The deposits, which were first detected in the early 1990s, were thought to be thick layers of nearly pure water ice. A new study published in the Planetary Science Journal was able to characterize the icy deposits in Mercury's north pole in greater detail and has provided a more robust way of finding and s Roman Telescope could help find other Earths by surveying space dust

A team of scientists found NASA's Nancy Grace Roman Space Telescope will be able to measure a specific kind of space dust littered throughout dozens of nearby planetary systems' habitable zones, or the regions around stars where temperatures are mild enough that liquid water could pool on worlds' surfaces.

Aided by microbes found in the subarctic conditions of Canada's Hudson Bay, an international team - including researchers from Portugal's Instituto Superior de Agronomia and Tecnico, Canada's Universite Laval in Quebec, and Cornell - has created the first color catalog of icy planet surface signatures to uncover the existence of life in the cosmos.

There's a powerful new member of NASA's family of giant antennas that enable engineers and scientists on Earth to communicate with the growing number of spacecraft exploring our solar system.
Called Deep Space Station 53, or DSS-53, the 111-foot (34-meter) antenna is part of NASA's Deep Space Network (DSN).

'Visionary' US astrophysicist Eugene Parker dead at 94

Eugene Parker, a pioneering American astrophysicist whose mathematical prediction that charged particles streamed from stars in a solar wind was met with disbelief before he was ultimately vindicated, has died aged 94, NASA said on Wednesday.
Parker was hailed as a visionary who laid the groundwork for the field of heliophysics, the science of understanding the Sun and its interactions with Earth and the solar system, including space weather.
In 2018, he became the first person to witness the launch of a spacecraft bearing his name, NASA's Parker Solar Probe.
