NASA’s Psyche En Route to Asteroid: Unlocking the Secrets of Planet Formation

On Earth, the planet’s iron core is responsible for the magnetic field that shields our atmosphere and enables life.

Led by Arizona State University on NASA’s behalf, the $1.2 billion mission will use a roundabout route to get to the asteroid. The van-size spacecraft with solar panels big enough to fill a tennis court will swoop past Mars for a gravity boost in 2026. Three years later, it will reach the asteroid and attempt to go into orbit around it, circling as high as 440 miles (700 kilometers) and as close as 47 miles (75 kilometers) until at least 2031.

The spacecraft relies on solar electric propulsion, using xenon gas-fed thrusters and their gentle blue-glowing pulses. An experimental communication system is also along for the ride, using lasers instead of radio waves in an attempt to expand the flow of data from deep space to Earth. NASA expects the test to yield more than 10 times the amount of data, enough to transmit videos from the moon or Mars one day.

The spacecraft should have soared a year ago, but was held up by delays in flight software testing attributed to poor management and other issues. The revised schedule added extra travel time. So instead of arriving at the asteroid in 2026 as originally planned, the spacecraft won’t get there until 2029.

That’s the same year that another NASA spacecraft — the one that just returned asteroid samples to the Utah desert — will arrive at a different space rock as it buzzes Earth.

The Psyche Mission

A Historic Launch:
Amidst great anticipation, Psyche successfully launched from NASA’s Kennedy Space Center in Florida. This momentous event marked the first-ever voyage to a metal-rich asteroid. As the spacecraft soared towards its destination, the fairings detached from the rocket, returning to Earth, and an hour later, Psyche separated from the rocket, preparing for the next phase of its mission.

Unveiling the Mysteries of Psyche:
Psyche promptly entered a planned safe mode, awaiting further commands from mission controllers on Earth. The spacecraft established communication with NASA’s Deep Space Network complex in Canberra, Australia, confirming its good health. With two-way communication established, scientists eagerly anticipate the treasure trove of scientific knowledge that Psyche will unlock.

A Metal World to Explore:
By August 2029, Psyche will begin orbiting the 173-mile-wide asteroid, becoming the first mission to explore a metal-class asteroid. With its high iron-nickel content, Psyche may be the remnant core of a planetesimal, offering valuable insights into the early stages of planet formation. This 26-month science investigation holds immense potential for expanding our understanding of the universe and our place within it.

The Journey and Propulsion System:
Psyche’s journey to the main asteroid belt between Mars and Jupiter spans six years and covers a distance of 2.2 billion miles. Powered by solar electric propulsion, the spacecraft employs charged atoms of xenon gas to create thrust, gently propelling it forward. Along the way, Psyche will utilize Mars’ gravity as a slingshot, further accelerating its journey towards the asteroid.

The Commissioning Phase:
The initial 100 days of the mission comprise a commissioning phase, during which all flight systems undergo thorough checks to ensure their health. Of particular importance is the readiness of the electric thrusters to continuously fire over long stretches of the trajectory. Simultaneously, the science instruments, including a magnetometer, gamma-ray and neutron spectrometer, and multispectral imager, will undergo active checkout.

Advancing Optical Communications:
One of the significant technological advancements accompanying the Psyche mission is NASA’s Deep Space Optical Communications technology demonstration. Approximately three weeks into the mission, when Psyche is approximately 4.7 million miles away from Earth, this technology will be powered on. This marks NASA’s first test beyond the Moon of high-data-rate optical communications, a critical capability for future space exploration.

As Psyche embarks on its mission to unravel the mysteries of the metal-rich asteroid, excitement and anticipation fill the air. The discoveries made during this journey hold the potential to reshape our understanding of planet formation and evolution. Moreover, the technological advancements demonstrated by the Deep Space Optical Communications technology will pave the way for bolder goals and greater achievements in space exploration. NASA’s commitment to exploring the unknown and inspiring the world through discovery has never been stronger.

Mysterious Lights Over Oregon: Pilots Report Unusual Aerial Phenomena

Published

on

Oregon

This past weekend, the skies of Oregon became the backdrop for an extraordinary event that has both puzzled and dazzled observers. At least four commercial pilots reported encountering unexplained bright lights displaying incredible speeds and erratic movements, renewing interest and debate about aerial phenomena.

The Encounter Details

The first report came from a pilot operating an air ambulance who described a startling experience. A bright, red light zoomed towards his Life Flight plane, only to reverse direction and head back towards the Pacific Ocean at bewildering speeds. The event left the pilot and his crew astounded by the light’s velocity and abrupt maneuvers.

Meanwhile, the pilot of a United Airlines flight over Eugene also reported seeing multiple mysterious objects. These unidentified lights moved vertically and horizontally in patterns that defied easy explanation, with no evidence of military activity in the area at the time.

Adding to the intrigue, the Life Flight pilot noted that one of the lights engaged in a corkscrew pattern, an observation that was corroborated by the aircraft’s collision avoidance system. Air traffic control, maintaining a cautious approach, authorized the pilot to maneuver as necessary to maintain safety.

Experts Weigh In: Possible Explanations

In the wake of these mystifying sightings, experts have been quick to offer explanations. Douglas Buettner, a scientist who has researched similar incidents, suggests that these lights could likely be flares from Starlink satellites. Starlink, a constellation designed by SpaceX to provide global broadband coverage, has been known to produce vivid optical flares when its panels reflect sunlight.

Buettner’s research, which includes previous pilot reports and observations, supports the idea that this natural reflection of sunlight could explain the phenomena observed. However, he also admits the current data is insufficient to conclusively rule out other possibilities.

Government and Public Response

Following these reports, the Federal Aviation Administration (FAA) confirmed the sighting of unidentified lights by a pilot, although they have not commented further. In a recent Senate hearing, the Pentagon’s director overseeing unidentified anomalous phenomena indicated a spike in such reports since the launch of satellite constellations like Starlink, underscoring the growing interest and concern regarding these observations.

The Broader Implications

While the most likely explanation for these mysterious lights points to satellite flares, the repeated occurrences of such phenomena continue to stir the public’s imagination and scientific curiosity. As we advance in our technological capabilities, the skies above us grow increasingly populated with human-made objects that can sometimes return to us as bewildering spectacles.

Listening for the right radio signals could be an effective way to track small drones

Unidentified drone sightings near sensitive U.S. locations raise public concern. Challenges exist in tracking these drones, necessitating better detection methods and potential regulatory changes for airspace management.

The recent spate of unidentified drone sightings in the U.S., including some near sensitive locations such as airports and military installations, has caused significant public concern.

Some of this recent increase in activity may be related to a September 2023 change in U.S. Federal Aviation Administration regulations that now allow drone operators to fly at night. But most of the sightings are likely airplanes or helicopters rather than drones.

The inability of the U.S. government to definitively identify the aircraft in the recent incidents, however, has some people wondering, why can’t they?

I am an engineer who studies defense systems. I see radio frequency sensors as a promising approach to detecting, tracking and identifying drones, not least because drone detectors based on the technology are already available. But I also see challenges to using the detectors to comprehensively spot drones flying over American communities.

How drones are controlled

Operators communicate with drones from a distance using radio frequency signals. Radio frequency signals are widely used in everyday life such as in garage door openers, car key fobs and, of course, radios. Because the radio spectrum is used for so many different purposes, it is carefully regulated by the Federal Communications Commission.

Drone communications are only allowed in narrow bands around specific frequencies such as at 5 gigahertz. Each make and model of a drone uses unique communication protocols coded within the radio frequency signals to interpret instructions from an operator and to send data back to them. In this way, a drone pilot can instruct the drone to execute a flight maneuver, and the drone can inform the pilot where it is and how fast it is flying.

Identifying drones by radio signals

Radio frequency sensors can listen in to the well-known drone frequencies to detect communication protocols that are specific to each particular drone model. In a sense, these radio frequency signals represent a unique fingerprint of each type of drone.

In the best-case scenario, authorities can use the radio frequency signals to determine the drone’s location, range, speed and flight direction. These radio frequency devices are called passive sensors because they simply listen out for and receive signals without taking any active steps. The typical range limit for detecting signals is about 3 miles (4.8 kilometers) from the source.

These sensors do not represent advanced technology, and they are readily available. So, why haven’t authorities made wider use of them? https://www.youtube.com/embed/9yFzdpEqQCs?wmode=transparent&start=0 Drones were all the buzz in the Northeast at the end of 2024.

Challenges to using radio frequency sensors

While the monitoring of radio frequency signals is a promising approach to detecting and identifying drones, there are several challenges to doing so.

First, it’s only possible for a sensor to obtain detailed information on drones that the sensor knows the communication protocols for. Getting sensors that can detect a wide range of drones will require coordination between all drone manufacturers and some central registration entity.

In the absence of information that makes it possible to decode the radio frequency signals, all that can be inferred about a drone is a rough idea of its location and direction. This situation can be improved by deploying multiple sensors and coordinating their information.

Second, the detection approach works best in “quiet” radio frequency environments where there are no buildings, machinery or people. It’s not easy to confidently attribute the unique source of a radio frequency signal in urban settings and other cluttered environments. Radio frequency signals bounce off all solid surfaces, making it difficult to be sure where the original signal came from. Again, the use of multiple sensors around a particular location, and careful placement of those sensors, can help to alleviate this issue.

Third, a major part of the concern over the inability to detect and identify drones is that they may be operated by criminals or terrorists. If drone operators with malicious intent know that an area targeted for a drone operation is being monitored by radio frequency sensors, they may develop effective countermeasures. For example, they may use signal frequencies that lie outside the FCC-regulated parameters, and communication protocols that have not been registered. An even more effective countermeasure is to preprogram the flight path of a drone to completely avoid the use of any radio frequency communications between the operator and the drone.

Finally, widespread deployment of radio frequency sensors for tracking drones would be logistically complicated and financially expensive. There are likely thousands of locations in the U.S. alone that might require protection from hostile drone attacks. The cost of deploying a fully effective drone detection system would be significant.

There are other means of detecting drones, including radar systems and networks of acoustic sensors, which listen for the unique sounds drones generate. But radar systems are relatively expensive, and acoustic drone detection is a new technology.

The way forward

It was almost guaranteed that at some point the problem of unidentified drones would arise. People are operating drones more and more in regions of the airspace that have previously been very sparsely populated.

Perhaps the recent concerns over drone sightings are a wake-up call. The airspace is only going to become much more congested in the coming years as more consumers buy drones, drones are used for more commercial purposes, and air-taxis come into use. There’s only so much that drone detection technologies can do, and it might become necessary for the FAA to tighten regulation of the nation’s airspace by, for example, requiring drone operators to submit detailed flight plans.

In the meantime, don’t be too quick to assume those blinking lights you see in the night sky are drones.
