This came as a complete surprise. Perseverance rover discovers igneous rocks at the bottom of a former lake

The Perseverance rover discovered volcanic rocks at the bottom of the Lake Lake crater, including basaltic rock from which Perseverance sampled.

The discovery of volcanic igneous rocks by NASA’s Perseverance rover at the bottom of Lake Jezero crater could hold clues to Mars’ climate history and pinpoint when it was wet and potentially habitable.

“We were very excited to find the igneous rocks,” Ken Farley, professor of geochemistry at the California Institute of Technology (Caltech), a project contributor, told Space.com. The origin of Lake’s igneous rocks remains a mystery, Farley said, as there are no obvious volcanic features in or near the crater.

The discovery of volcanic rocks came as a complete surprise, as the Perseverance rover was expected to land on sedimentary rocks formed from mud and detritus deposited by an ancient lake that filled the rover’s landing site, Lake Crater, about 3.7 billion years ago.

Perseverance landed on Mars on February 18, 2021, with the 45-kilometer-wide Lake Crater chosen as the landing site because of the extremely prominent and ancient river delta that flows into the crater. Planetary scientists and astrobiologists hope that such an environment would have been favorable for life billions of years ago.

Some of the rocks found in Jezero Crater have similar compositions to rocks from deep within the Earth, where the oxidation of iron through interaction with water can produce molecular hydrogen (a potential energy source for microbial life) and hydrocarbons such as methane? which can serve as the building blocks of some of life’s more complex connections.

Firefly Aerospace a private space company successfully launched a rocket

Firefly Aerospace has successfully launched an Alpha rocket and placed seven research mini-satellites into orbit. Some of them were launched in the interests of NASA, there are also satellites created in Spain and Greece. The launch was made from the base of the US Space Force Wadenberg.

Firefly Aerospace, a private space company, successfully launched a rocket and put several mini-satellites into orbit.

The Alpha rocket is a lightweight rocket, meaning it can launch approximately 1.2 tons of payload. This is the second rocket launch, the first took place in September last year, but the rocket exploded after launch due to the failure of one of the engines. This time everything went smoothly. The mission itself is called Alpha Flight 2: To The Black.

At the same time, the launch was originally planned for the morning of September 30, but the rocket engines turned off almost immediately after they were launched – the automatic abort system worked. The reasons for this were not explained, the company only reported that such behavior was provided for by the security system.

Firefly Aerospace intends to take part of the small satellite launch market. Each launch is valued at $15 million. Thus, the company intends to compete with SpaceX, Rocket Lab, Virgin Orbit and Astra. Firefly Aerospace is a privately held aerospace company headquartered in Austin, Texas.
