Planetary scientists from Rice University, NASA's Johnson Space Center and the California Institute of Technology have an answer to a mystery that's puzzled the Mars research community since NASA's Curiosity rover discovered a mineral called tridymite in Gale Crater in 2016.
Tridymite is a high-temperature, low-pressure form of quartz that is extremely rare on Earth, and it wasn't immediately clear how a concentrated chunk of it ended up in the crater. Gale Crater was chosen as Curiosity's landing site due to the likelihood that it once held liquid water, and Curiosity found evidence that confirmed Gale Crater was a lake as recently as 1 billion years ago.

NASA wants your help designing a starshade to observe exoplanets
Monday, 25 July 2022 12:21 Write a comment
The field of exoplanet study has come a long way in recent decades. To date, 5,063 exoplanets have been confirmed in 3,794 systems beyond our own, with another 8,819 candidates awaiting confirmation. In the coming years, tens of thousands of more planets are expected to be found, thanks to next-generation observatories. The ultimate goal in this search is to find planets that are "Earth-like," meaning they have a good chance of supporting life. This is no easy task, as rocky planets located within their parent star's habitable zones (HZs) tend to orbit closely, making them harder to see.
To make this process easier, NASA is designing a hybrid observatory consisting of a "Starshade" that will block out a star's light so that a ground-based telescope can directly image planets orbiting it.
Chinese astronauts set up new lab on space station

Astronauts entered the new lab module of China's space station for the first time Monday, in a major step towards completing the orbital outpost by the end of the year.
The station is one of the crown jewels of Beijing's ambitious space programme, which has landed robotic rovers on Mars and the Moon, and made China only the third nation to put humans in orbit.

DARPA's Hypersonic Air-breathing Weapon Concept (HAWC), a missile program conducted in partnership with the U.S. Air Force, completed another successful free flight in early July. This is the second demonstration vehicle built by Raytheon Technologies to meet test objectives. The first Raytheon flight was in September 2021. It was followed by success with a different contractor's vehicle configu SpaceX launches another 53 Starlink satellites in sixth launch of month

SpaceX sent another 53 Starlink satellites into orbit Sunday with its 33rd launch of the year, just days after the company broke its annual record set in 2021.
That satellites were sent into low-Earth orbit from Launch Complex 39A at Kennedy Space Center in Florida at 9:38 a.m. EDT, the company said in a statement.

Scientists from NASA's OSIRIS-REx mission recently learned that surface regeneration happens a lot quicker on asteroids than on Earth. By analyzing rock fractures on asteroid Bennu from high-resolution images taken by the OSIRIS-REx spacecraft, the team discovered that the Sun's heat fractures rocks on Bennu in just 10,000 to 100,000 years. This information will help scientists estimate how long How do collisions of rocks with planets help the planets evolve?

Planetary scientist Katarina Miljkovic is available to discuss the nature of planets in Melbourne this week. It's part of a national tour of public and school talks promoting opportunities for women in physics.
The planets in our solar system are vastly different although they all formed from the same cloud of gas and dust around a star - our sun. Why is this?

China plans to launch a large space telescope next year to fly alongside the Tiangong space station, according to the China Academy of Launch Vehicle Technology.
The academy said a Long March 5B heavy-lift carrier rocket will deploy the Xuntian space telescope in a low-Earth orbit similar to the track of the Tiangong station as they both circle Earth. The telescope will carry out deep-spac Hawkeye 360 opens new satellite manufacturing facility
