SAN ANTONIO Feb. 22, 2021 From aboard the Juno spacecraft, a Southwest Research Institute-led instrument observing auroras serendipitously spotted a bright flash above Jupiter s clouds last spring. The Ultraviolet Spectrograph (UVS) team studied the data and determined that they had captured a bolide, an extremely bright meteoroid explosion in the gas giant s upper atmosphere. Jupiter undergoes a huge number of impacts per year, much more than the Earth, so impacts themselves are not rare, said SwRI s Dr. Rohini Giles, lead author of a paper outlining these findings in
German Aerospace Center scientists. The researchers launched these small lifeforms into Earth s stratosphere, which replicates key characteristics of the Martian environment, and found that some microorganisms, in particular spores of black mold, survived the trip. This new way of testing endurance to space travel will be invaluable for understanding the threats and opportunities of microbes in future missions to Mars.

A boost to innovation and competitiveness
The joint project researches how increasing the efficiency of forestry s value chain can benefit from optical measurement technology and satellite data. The partners are researching concrete applications and mapping which actors would be able to utilise the new technologies in their operations.
- We have noticed that companies in many sectors should speed up their digitalisation activities and find new ways of utilising technology that would support this process. Both optical measurement technology and satellite data can offer new solutions that increase the efficiency of various functions and thus drive both innovation and competitiveness, both of which are important particularly in a pandemic situation, says Adopticum s CEO Kenth Johansson.

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.

HANOVER, N.H. - February 12, 2021 - A newly discovered planetary system will provide researchers with the rare chance to study a group of growing planets, according to research co-led by Dartmouth.
The new system, named TOI 451, is made up of at least three neighboring planets that orbit the same sun. The planets range in size between that of Earth and Neptune.
According to the research team, NASA s Hubble Space Telescope and its planned successor, the James Webb Space Telescope, can be used to study the atmosphere of each planet. Such research could lead to information on how planetary systems like our own solar system evolve.
