Searching for dark matter through the fifth dimension
Monday, 01 February 2021 08:48
Theoretical physicists of the PRISMA+ Cluster of Excellence at Johannes Gutenberg University Mainz are working on a theory that goes beyond the Standard Model of particle physics and can answer questions where the Standard Model has to pass - for example, with respect to the hierarchies of the masses of elementary particles or the existence of dark matter.

Monday, 01 February 2021 08:48
The Milky Way is surrounded by dozens of dwarf galaxies that are thought to be relics of the very first galaxies in the universe. Among the most primitive of these galactic fossils is Tucana II - an ultrafaint dwarf galaxy that is about 50 kiloparsecs, or 163,000 light years, from Earth.
Now MIT astrophysicists have detected stars at the edge of Tucana II, in a configuration that is surpri Kongsberg Geospatial improves BVLOS drone operations safety with a horizonless air picture

On Nov. 26, seven fishermen aboard a small fishing boat off the coast of Maharashtra in western India were struck with panic when their vessel was damaged and began to sink. The panic was warranted: The boat was too far from shore to radio for help.
Tens of thousands of fishermen find themselves in a similar situation around the world every year. Globally, the vast majority of small, deep- Hawkeye 360 deploys next-generation radio frequency sensing satellites

HawkEye 360 Inc., the first commercial company to use formation-flying satellites to create a new class of radio frequency (RF) data and data analytics, has announced that Cluster 2 - the company's second cluster of satellites - has successfully been deployed into orbit.

A common misconception about astronauts orbiting the earth is that they are in a gravity-free environment. Unfortunately, according to Newtonian physics, gravity is everywhere present in the universe. Generally, the phenomenon of weightlessness is associated with the term, "zero-G" which would apply to situations in which there is an absence of forces on a body.
Weight as we know it is the Earth observation vital in monitoring wetland waters

Celebrated annually on 2 February, World Wetlands Day aims to raise global awareness about the importance of wetlands for our planet. This year’s theme shines a light on wetlands as a source of freshwater and encourages actions to restore them. From their vantage point of 800 km high, Earth-observing satellites provide data and imagery on wetlands that can be used to monitor and manage these precious resources sustainably.

Space tourism: new test flight planned for Virgin Galactic
Sunday, 31 January 2021 19:55
Space tourism company Virgin Galactic said Monday it planned a new test flight for its SpaceShipTwo craft this month after an aborted test in early December.
"The flight window will open on February 13 with opportunities to fly throughout February, pending good weather conditions and technical readiness," Richard Branson's company said.
"Pre-flight preparations are already underway at Spaceport America, New Mexico."
It added the flight would test remedial work completed since the December test when the onboard computer halted ignition of the rocket motor.
SpaceShipTwo had been expected to take its first passengers into space later this year.
So far, 600 people who have paid up to $250,000—Virgin Galactic calls them "future astronauts"—have been waiting for years to take their seat.
SpaceShipTwo's development was delayed by a devastating crash of the first one in 2014 due to a pilot error.
When fully functional, the spacecraft will be taken up by a special plane and released at high altitude.

Apes, robots and men: The life and death of the first space chimp
Sunday, 31 January 2021 15:15
On January 31, 1961, an intrepid chimpanzee called Ham was launched on a rocket from Cape Canaveral in the United States, and returned to Earth alive. In this process, he became the first hominin in space.
In the 1950s, it was unclear whether humans could survive outside Earth—both physically and mentally. The science fiction writer and warfare expert Cordwainer Smith wrote about the psychological pain of being in space.
Plants, insects and animals had been taken to high altitudes in balloons and rockets since the 18th century. The Soviet Union sent the dog Laika into orbit on Sputnik 2 in 1957. She died, but from overheating rather than the effects of space travel itself.
While the USSR focused on dogs, the US turned to chimpanzees as they were the most like humans. The stakes became higher when US President John F. Kennedy promised to land humans on the Moon by the end of the 1960s.
Biography of a non-human astronaut
Ham was born in 1957 in a rainforest in the Central African nation of Cameroon, then a French territory.
