NASA chooses a trio of proposals for understanding space weather

NASA has announced that it has selected three proposals for concept studies that aim to help understand the dynamic space weather system driven by the sun near the Earth. The proposals will examine what drives different parts of that system and what will ultimately help us to predict and mitigate the effects on spacecraft and astronauts. Each of the Heliophysics Mission of Opportunity is funded with $400,000.

Caltech study finds internal pressures drop after planetary collisions

Caltech study finds internal pressures drop after planetary collisions

A new study out of Caltech has the potential to change how scientists think internal pressures in planets evolve over time. The study has found that massive impacts of patents hitting each other could significantly change the current model of planetary formation. One major impact with the Earth about 4.5 billion years ago is believed to be what caused the formation of the Moon.

AIDA team-up aims to test asteroid deflection

AIDA team-up aims to test asteroid deflection

Asteroid researchers and spacecraft designers are meeting up in Rome next week to discuss a common goal of a double spacecraft mission to deflect an asteroid in space. The scientists want to prove if their technique is a viable method of planetary defense against asteroids. The mission is known as Asteroid Impact Deflection Assessment or AIDA.

Newly developed Iron-ion battery could be a cheap alternative

Newly developed Iron-ion battery could be a cheap alternative

A team of researchers from the Indian Institute of Technology has announced the development of the world's first iron-ion battery. The new battery tech promises to be a low-cost and stable alternative to existing lithium-ion battery technology. A battery is made of an anode that uses low-carbon steel rather than pure iron along with a cathode of vanadium pentoxide.

ESA satellite had to fire thrusters to avoid a collision in orbit

ESA satellite had to fire thrusters to avoid a collision in orbit

The ESA has announced that its Earth-observing satellite called Aeolus had to fire its thrusters to avoid a potential collision with one of the satellites in the SpaceX Starlink mega constellation. The ESA stated that the avoidance maneuver took place only half an orbit before the collision could have occurred. Space agencies all around the world track satellites and space debris in hopes of avoiding a collision.

Indian moon orbiter releases Vikram lander

Indian moon orbiter releases Vikram lander

Last month the Indian Space Research Organisation (ISRO) successfully put its Chandrayaan-2 orbiter into orbit around the moon. The two halves of the orbiter have now separated in preparation for the Vikram lander portion of the spacecraft touching down on the surface of the Moon. The separation of the two portions of the spacecraft happened yesterday.

MIT created a robotic thread for clearing brain vessel blockages

MIT created a robotic thread for clearing brain vessel blockages

MIT has invented a new robotic thread that is small enough to travel through the blood vessels inside the human brain. The robotic thread is controlled using magnets to actively guide it through the narrow and winding passages inside the vasculature of the brain. The team thinks that the invention could be used in the future to treat people suffering from stroke or aneurysm.

MIT autonomous robot boats gain the ability to change shape

MIT autonomous robot boats gain the ability to change shape

Back in June, we talked about some new autonomous robot boats that had been invented by MIT. These boats were designed to find and attach to each other while floating in the canals of Amsterdam to pick up trash. MIT has announced an improvement to its robotic boats that could make them more efficient at picking up garbage.

International Space Station gets 600 Mbps data rate upgrade

International Space Station gets 600 Mbps data rate upgrade

The International Space Station has received a 600 Mbps data rate upgrade, according to NASA, enabling astronauts and control centers on Earth to communicate at faster rates. The upgrade doubles the ISS's data rate, making it possible to conduct new types of tech demonstrations and scientific experiments that come with more demanding data requirements. This upgrade will also play an important role in communication capabilities for the future Gateway station.

NASA will test quiet supersonic jet using 30-mile-long microphone array

NASA will test quiet supersonic jet using 30-mile-long microphone array

Quiet supersonic jets may one day fly over land to offer faster commercial and passenger flights. Before that can happen, however, the FAA will need to establish new rules regarding these typically noisy flights. To help usher in that era, NASA plans to test Lockheed Martin's X-59 QueSST, an experimental supersonic jet that produces a 'thump' instead of a 'boom,' something the space agency will verify using a microphone array that is 30 miles long.

NASA video shows Hurricane Dorian from the International Space Station

NASA video shows Hurricane Dorian from the International Space Station

NASA has shared a video showing Hurricane Dorian as seen from the International Space Station. The storm was captured as it 'churned over the Atlantic Ocean,' according to the space agency, which caught views of the hurricane during the early afternoon on August 29. In addition to sharing the video on YouTube, NASA is also making the footage available for the public to download.
