It is clear to everyone that astronomy at all events compels the soul to look upwards, and draws it from the things of this world to the other.

JWST finds spiral galaxy about 5 times more massive than Milky Way — scientists call it 'Big Wheel'

Space.com - 6 hours 47 min ago
Scientists have uncovered a massive galaxy that existed just 2 billion years after the Big Bang. But how did this colossal "Big Wheel" form so early in the universe? The answer could change everything we know about galaxy growth.

Lunar Regolith Could Power a Future Lunar Station

Universe Today - 8 hours 19 min ago

Any advanced civilisation needs power. Don’t know about you but I’ve been camping lots, even wild camping but the experience is a whole lot easier if you have power! It’s the same for a long-term presence on the Moon (not that I’m likening my camping to a trip to the Moon!) but instead of launching a bunch of solar panels, a new paper suggests we can get power from the lunar regolith! Researchers suggest that the fine dusty material on the surface of the Moon could be melted to provide a type of crystals that can produce solar electricity! This would allow solar panels to be built on the Moon with only 1% of components sent from Earth!

NASA's Rover to Explore the Lunar South Pole Is Taking Shape

Universe Today - Thu, 04/03/2025 - 6:03pm

Sometimes, a brief update is all that is needed to keep the public interested in major projects. That's precisely what John Baker and James Keane of NASA's Jet Propulsion Laboratory provided to the 56th annual Lunar and Planetary Science Conference held in Texas last month. Their brief paper showcased the ongoing development of the Endurance autonomous rover, which was more thoroughly fleshed out in a massive 296-page mission concept study back in 2023. But what has the team been up to since then?

NASA Supports Wildland Fire Technology Demonstration

NASA News - Thu, 04/03/2025 - 4:52pm

3 min read

Preparations for Next Moonwalk Simulations Underway (and Underwater) Drones were a key part of testing new technology in support of a prescribed burn in Geneva State Forest, which is about 100 miles south of Montgomery, Alabama. The effort is part of the agency’s multi-year FireSense project, which is aimed at testing technologies that could eventually serve the U.S. Forest Service as well as local, state, and other federal wildland fire agencies.

Advancements in NASA’s airborne technology have made it possible to gather localized wind data and assess its impacts on smoke and fire behavior. This information could improve wildland fire decision making and enable operational agencies to better allocate firefighters and resources. A small team from NASA’s Armstrong Flight Research Center in Edwards, California, is demonstrating how some of these technologies work.

Two instruments from NASA’s Langley Research Center in Hampton, Virginia – a sensor gathering 3D wind data and a radiosonde that measures temperature, barometric pressure, and humidity data – were installed on NASA Armstrong’s Alta X drone for a prescribed burn in Geneva State Forest, which is about 100 miles south of Montgomery, Alabama. The effort is part of the agency’s multi-year FireSense project, which is aimed at testing technologies that could eventually serve the U.S. Forest Service as well as local, state, and other federal wildland fire agencies.

“The objectives for the Alta X portion of the multi-agency prescribed burn include a technical demonstration for wildland fire practitioners, and data collection at various altitudes for the Alabama Forestry Commission operations,” said Jennifer Fowler, FireSense project manager. “Information gathered at the different altitudes is essential to monitor the variables for a prescribed burn.”

Those variables include the mixing height, which is the extent or depth to which smoke will be dispersed, a metric Fowler said is difficult to predict. Humidity must also be above 30% for a prescribed burn. The technology to collect these measurements locally is not readily available in wildland fire operations, making the Alta X and its instruments key in the demonstration of prescribed burn technology.

In addition to the Alta X flights beginning March 25, NASA Armstrong’s B200 King Air will fly over actively burning fires at an altitude of about 6,500 feet. Sensors onboard other aircraft supporting the mission will fly at lower altitudes during the fire, and at higher altitudes before and after the fire for required data collection. The multi-agency mission will provide data to confirm and adjust the prescribed burn forecast model.

Small, uncrewed aircraft system pilots from NASA Armstrong completed final preparations to travel to Alabama and set up for the research flights. The team – including Derek Abramson, chief engineer for the subscale flight research laboratory; Justin Hall, NASA Armstrong chief pilot of small, uncrewed aircraft systems; and Alexander Jaffe, a drone pilot – will set up, fly, observe airborne operations, all while keeping additional aircraft batteries charged. The launch and recovery of the Alta X is manual, the mission profile is flown autonomously to guarantee the same conditions for data collection.

“The flight profile is vertical – straight up and straight back down from the surface to about 3,000 feet altitude,” Abramson said. “We will characterize the mixing height and changes in moisture, mapping out how they both change throughout the day in connection with the burn.”

In August 2024, a team of NASA researchers used the NASA Langley Alta X and weather instruments in Missoula, Montana, for a FireSense project drone technology demonstration. These instruments were used to generate localized forecasting that provides precise and sustainable meteorological data to predict fire behavior and smoke impacts.

Here's How We Could Quickly Raise Temperatures on Mars

Universe Today - Thu, 04/03/2025 - 4:00pm

Mars is a cold, dry desert, but it could be possible to rapidly increase the temperature of the planet by releasing particles into the atmosphere. Researchers investigated two possible chemicals: graphene or aluminum. With just two liters per second of release, we could double the Mars greenhouse effect, raising its temperature by +5 Kelvin in only 1.1 years. Once the chemical release is stopped, the planet would cool back to its normal state.
