If you’ve ever dreamed of becoming an astronaut, the European Space Agency is seeking a new cohort of astronauts for the first time in 13 years.
The genius behind the space probe’s landing on Mars.
As NASA’s Mars 2020 mission gets set to land its package on the surface of the red planet, NASA engineers, including Dr Swati Mohan, who has led the attitude control system of Mars 2020 mission during operations, will be counting some very anxious minutes.
NASA asks the engineers and scientists behind the rover to make this daily change for three months, sometimes working overnight.
Every day space telescopes provide spectacular images of the solar activity. However, their instruments are blind to its main driver: the magnetic field in the outer layers of the solar atmosphere, where the explosive events that occasionally affect the Earth occur. The extraordinary observations of the polarization of the Sun’s ultraviolet light achieved by the CLASP2 mission have made it possible to map the magnetic field throughout the entire solar atmosphere, from the photosphere until the base of the extremely hot corona. This investigation, published today in the journal Science Advances, has been carried out by the international team responsible for this suborbital experiment, which includes several scientists of the POLMAG group of the Instituto de Astrofísica de Canarias (IAC).
The chromosphere is a very important region of the solar atmosphere spanning a few thousand kilometers between the relatively thin and cool photosphere (with temperatures of a few thousand degrees) and the hot and extended corona (with temperatures above a million degrees). Although the temperature of the chromosphere is about one hundred times lower than that of the corona, the chromosphere has a far higher density, and thus much more energy is required to sustain it. Moreover, the mechanical energy necessary to heat the corona needs to traverse the chromosphere, making it a crucial interface region for the solution of many of the key problems in solar and stellar physics. One of the current scientific challenges is to understand the origin of the violent activity of the solar atmosphere, which on some occasions perturb the Earth’s magnetosphere with serious consequences for our present technological world.
When enough anomalies accumulate over time, paradigms change. We may be close to that inflection point right now. At this juncture of technoscientific progress, the boldest of us may admit that we’re overdue for the next post-materialist paradigm: Conventional scientific method is already bankrupt and needs to be supplanted by AI-powered quantum neo-empiricism, computational thinking and the cybernetic approach to reality.

The spacecraft InSight detected tremors from deep underneath the rust-colored surface of Mars indicating, for the first time ever, that the planet is geologically active.
Planetary scientists have revealed some of the Red Planet’s subterranean secrets.
The six-wheeled robot’s latest data since touching down yesterday include a series of images captured as the rover’s “jet pack” lowered it to the ground.
Less than a day after NASA ’s Mars 2020 Perseverance rover successfully landed on the surface of Mars, engineers and scientists at the agency’s Jet Propulsion Laboratory in Southern California were hard at work, awaiting the next transmissions from Perseverance. As data gradually came in, relayed by several spacecraft orbiting the Red Planet, the Perseverance team were relieved to see the rover’s health reports, which showed everything appeared to be working as expected.
NEW: A new photo from NASA rover Perseverance’s “jetpack” shows the surface of Mars just before it touched down on the Red Planet.
