The Air Force Research Laboratory's, or AFRL, newest sensor experiment deployed from the International Space Station Dec. 29, 2022, hosted on NASA's six-unit cube satellite named petitSat, or Plasma Enhancements in the Ionosphere-Thermosphere Satellite. The CubeSat's mission is to study a layer in Earth's upper atmosphere known as the ionosphere to provide insight into space weather distur
IBM (NYSE: IBM) and NASA's Marshall Space Flight Center have announced a collaboration to use IBM's artificial intelligence (AI) technology to discover new insights in NASA's massive trove of Earth and geospatial science data. The joint work will apply AI foundation model technology to NASA's Earth-observing satellite data for the first time. Foundation models are types of AI models that a
Creeping from just a finger's width up to a few feet per year, slow-moving landslides occur naturally throughout the world. They typically are detected inching downslope in rocky areas with high seasonal precipitation and clay-rich soil, and they can take months to years - even centuries - to develop. Yet they can also bring sudden violence. Thousands of landslides are flowing, slipping, topplin
The 'mirrors' exist for only a fragment of time but could help to reduce the size of ultra-high power lasers, which currently occupy buildings the size of aircraft hangars, to university basement sizes. They have potential to be developed into a variety of plasma-based, high damage-threshold optical elements that could lead to small footprint, ultra-high-power, ultra-short pulse laser syst
A collaboration between scientists at Cambridge and UCL has led to the discovery of a new form of ice that more closely resembles liquid water than any other and may hold the key to understanding this most famous of liquids. The new form of ice is amorphous. Unlike ordinary crystalline ice where the molecules arrange themselves in a regular pattern, in amorphous ice the molecules are in a
If she hits just the right pitch, a singer can shatter a wine glass. The reason is resonance. While the glass may vibrate slightly in response to most acoustic tones, a pitch that resonates with the material's own natural frequency can send its vibrations into overdrive, causing the glass to shatter. Resonance also occurs at the much smaller scale of atoms and molecules. When particles che
NASA's Perseverance Mars Rover took an image on December 18th, 2022, during its 650th day of mission that captured the Mars Helicopter Ingenuity near the base of Jezero Crater's river delta, approximately 1,115 feet (340 meters) away from the rover. The image was captured using the left camera of Mastcam-Z with an RGB color filter and the middle of its seven zoom settings, at a focal length of 6
The drive in our last plan took us to an area that appeared somewhat smoother and brighter from orbit (as well as from drive direction imaging) on the so-called "Marker band" that we have been investigating. The Marker band was identified as of interest prior to Curiosity landing within Gale crater owing to its distinct texture and appearance from orbit within the layers of rock that make up Mou
Mars clouds are very much like Earth's cirrus clouds but thinner. While Earth clouds can contain liquid water, the low temperatures and pressures on Mars only allow for water-ice (and CO2 ice) clouds to form. However, these water-ice clouds are optically thin because of the low amounts of water present in the Martian atmosphere; if all the water were on the surface, it would make a layer thinner
A team of astronomers led by MPIA scientist Diana Kossakowski have discovered an Earth-mass exoplanet orbiting in the habitable zone of the red dwarf star Wolf 1069. Although the rotation of this planet, named Wolf 1069 b, is probably tidally locked to its path around the parent star, the team is optimistic it may provide durable habitable conditions across a wide area of its dayside. The absenc
Virgin Orbit (NASDAQ: VORB) and Poland-based satellite manufacturer SatRev announced a follow-on launch services agreement (LSA) for additional launches of SatRev's satellites in 2023 and beyond. This new agreement provides SatRev with the flexibility to launch 500 kg over multiple launches to a variety of different orbital planes from the Mojave Air and Space Port in California, USA and/o
Sidus Space, Inc. (Nasdaq: SIDU), reported Friday the closing of its underwritten public offering of 17,250,000 shares of its Class A common stock (or pre-funded warrants (the "Pre-Funded Warrants") in lieu thereof, which included the full exercise of the underwriters' over-allotment option. Each share of Class A common stock was sold to the public at a price of $0.30 per share. The gross
OneWeb, a company specializing in low Earth orbit satellite communications, has signed a Memorandum of Understanding (MoU) with the Kazakhstan National Railways Company "Kazakhstan Temir Zholy" to investigate providing high-speed, low-latency broadband satellite connectivity to railway stations and rolling stock throughout Kazakhstan. This collaboration aims to enhance the connectivity and
U.S. and Indian officials agreed this week to expand civil space cooperation, including training Indian astronauts and flying payloads on commercial lunar landers.
The White House on Feb. 3 announced the appointment of new members to President Biden’s National Security Telecommunications Advisory Committee.
