Psyche mission launches as NASA’s first trip to a metal world

(October 13, 2023)

To accomplish the rest of the mission, the van-size spacecraft will rely on its new solar electric propulsion system, powered by Hall-effect thrusters, Oh said. The thrusters will utilize the spacecraft’s large solar arrays and “use electricity to ionize xenon gas and accelerate those charged ions through an electric field to very, very high speeds,” Oh said. (…)

Also along for the ride is the Deep Space Optical Communications technology demonstration, or DSOC. Occurring during the first two years of the journey to Psyche, it will be NASA’s most distant experiment of high-bandwidth laser communications, testing the sending and receiving of data to and from Earth using an invisible near-infrared laser.

ILLUMA-T

NASA wants to update its existing radio communications system on the International Space Station (ISS) with optical communication technology. Optical communication systems, which use laser beams to transmit information through space, promise the ability to transmit data between a spacecraft and Earth at a much higher rate than radio-frequency systems. Our researchers are designing ILLUMA-T*, a laser terminal that will provide an optical communications link from the ISS to NASA‘s Laser Communications Relay Demonstration satellite, which, in turn, will use optical communications to relay the data from the ISS link to a ground terminal at a rate 10 to 100 times faster than current radio frequency communications systems.

NASA’s Laser Communications Relay: A Year of Experimentation

(Jun 28, 2023)

The Laser Communications Relay Demonstration (LCRD) uses infrared light, or invisible lasers, to transmit and receive signals rather than radio wave systems conventionally used on spacecraft. Infrared light’s tight wavelengths allow space missions to pack significantly more data – 10 to 100 times more – into a single transmission. More data means more discoveries.

Now, at the halfway point in its experimentation phase, LCRD has shown laser communications’ significant advantages over traditional radio wave systems.

Magnetic Portals Connect Earth to the Sun

Oct. 30, 2008: During the time it takes you to read this article, something will happen high overhead that until recently many scientists didn‘t believe in. A magnetic portal will open, linking Earth to the sun 93 million miles away. Tons of high-energy particles may flow through the opening before it closes again, around the time you reach the end of the page.

„It‘s called a flux transfer event or ‚FTE,'“ says space physicist David Sibeck of the Goddard Space Flight Center. „Ten years ago I was pretty sure they didn‘t exist, but now the evidence is incontrovertible.“

Indeed, today Sibeck is telling an international assembly of space physicists at the 2008 Plasma Workshop in Huntsville, Alabama, that FTEs are not just common, but possibly twice as common as anyone had ever imagined.

Sun‘s protective ‚bubble‘ is shrinking

(18.10.2008)

New data has revealed that the heliosphere, the protective shield of energy that surrounds our solar system, has weakened by 25 per cent over the past decade and is now at it lowest level since the space race began 50 years ago. (…)

„Around 90 per cent of the galactic cosmic radiation is deflected by our heliosphere, so the boundary protects us from this harsh galactic environment.“

The heliosphere is created by the solar wind, a combination of electrically charged particles and magnetic fields that emanate a more than a million miles an hour from the sun, meet the intergalactic gas that fills the gaps in space between solar systems.

A meteor crashed into Mars on Christmas Eve 2021, and shook the planet so much that NASA‘s InSight lander recorded the rumblings.

Scientists didn‘t know where the quake came from until NASA‘s Mars Reconnaissance Orbiter, a spacecraft circling the red planet, captured images of the new impact crater. NASA revealed the discovery on Thursday.

Studying the Edge of the Sun’s Magnetic Bubble

(Oct 19, 2021)

The space radiation that comes at us from other stars is called galactic cosmic radiation (GCR). Active areas in the galaxy – like supernovae, black holes, and neutron stars – can strip the electrons from atoms and accelerate the nuclei to almost the speed of light, producing GCR.

On Earth, we have three layers of protection from space radiation. The first is the heliosphere, which helps block GCR from reaching the major planets in the solar system. Additionally, Earth’s magnetic field produces a shield called the magnetosphere, which keeps GCR out away from Earth and low-orbiting satellites like the International Space Station. Finally, the gases of Earth’s atmosphere absorb radiation.

With NASA Data, Researchers Find Standing Waves at Edge of Earth’s Magnetic Bubble

(Oct.6, 2021)

The latest work considers the waves that form across the entire surface of the magnetosphere, using a combination of models and observations from NASA’s THEMIS mission, Time History of Events and Macroscale Interactions during Substorms.

The researchers found when solar wind pulses strike, the waves that form not only race back and forth between Earth’s magnetic poles and the front of the magnetosphere, but also travel against the solar wind. Archer likened these two kinds of movement to crossing a river: A boat can go from one riverbank to the other (traveling towards the poles) and upstream (against the solar wind). At the front of the magnetosphere, these waves appear to stand still.

NASA caught “adjusting” Global Temperature Graph — AGAIN

(July 20, 2021)

In what Dr Higgs calls yet another manipulation of the data, in early 2021, NASA discreetly lowered the 2016 global average temperature –previously the highest on record– to make the year 2020 seem like the hottest.

The Thermosphere Responds to a Weaker Than Normal Solar Cycle

(05.04.2019)

The cooling near solar minimum is natural and specific to the thermosphere. The cooling thermosphere does not affect the troposphere, the layer of the atmosphere closest to Earth’s surface where people live. The temperatures we experience on the ground do not get colder because of this solar cycle. NASA and other climate researchers continue to see a warming trend in the troposphere. These two effects are ongoing but unrelated.

Nitric oxide and carbon dioxide play important roles in cooling the thermosphere.
