Former U.S. Air Force Major Evan “Jolly” Rogers worries about space war. “Conflict exists on a continuum that starts with competition and eventually leads to full-scale conflict like you see in Ukraine,” he says. He adds that the US is already  “in active competition with Russia and China for freedom of action and dominance in the space domain. And it’s evolving very rapidly.”, Wired wrote on the subject.

That’s why on January 26 last year, the former US Air Force major registered True Anomaly to “solve the most complex orbital warfare problems for the US Space Force,” he later tweeted.

According to a recent filing with the US Federal Communications Commission (FCC), True Anomaly is already preparing for its first orbital mission. In October, True Anomaly hopes to launch two Jackal “orbital pursuit” spacecraft aboard a SpaceX rocket to low-Earth orbit. The Jackals won’t have weapons, warheads or laser blasters, but they will be able to perform rendezvous proximity operations (RPO) – the ability to maneuver near other satellites and use a battery of sensors.

Rogers’ latest job for the government is to lead teams at U.S. Space Command that plan how and when to deploy defensive and offensive military space systems. He and co-founders Dan Brunski, Tom Nichols and Kyle Zakrzewski, also former Air Force and Space Force officers, “knew the problem better than anyone, faced the limitations of the technology on a daily basis, and were frustrated by those limitations,” Rogers says.

True Anomaly has already raised more than $23 million from investors, according to the U.S. Securities and Exchange Commission. That includes a December investment from Narya, a venture capital firm co-founded by U.S. Sen. J.D. Vance, an Ohio Republican who is a MAGA supporter. (Rogers says True Anomaly itself has no political affiliation.)

Each collision in orbit could result in the formation of thousands of pieces of space junk, each of which could damage other satellites, creating even more debris. Researchers worry that the growth of orbital debris will eventually trigger a catastrophic cascade known as Kessler syndrome.

Rogers himself is no stranger to risk. Prior to founding True Anomaly, he founded and ran a crypto hedge fund called Phobos Capital. And before that, he registered a company called 3720 to 1 – a reference to Han Solo’s chances of successfully navigating an asteroid field in The Empire Strikes Back, according to C-3PO.

Whether Rogers’ quest for a satellite enterprise is more likely to succeed, or is just another piece of fiction, will become much clearer after SpaceX’s rocket launch in October.

A solar telescope has a tough job. Staring at the Sun takes a harsh toll, with a constant bombardment by a never-ending stream of solar particles and intense sunlight. Over time, the sensitive lenses and sensors of solar telescopes begin to degrade. To ensure the data such instruments send back is still accurate, scientists recalibrate periodically to make sure they understand just how the instrument is changing.

Launched in 2010, NASA’s Solar Dynamics Observatory, or SDO, has provided high-definition images of the Sun for over a decade. Its images have given scientists a detailed look at various solar phenomena that can spark space weather and affect our astronauts and technology on Earth and in space. The Atmospheric Imagery Assembly, or AIA, is one of two imaging instruments on SDO and looks constantly at the Sun, taking images across 10 wavelengths of ultraviolet light every 12 seconds. This creates a wealth of information of the Sun like no other, but—like all Sun-staring instruments—AIA degrades over time, and the data needs to be frequently calibrated.

Since SDO’s launch, scientists have used sounding rockets to calibrate AIA. Sounding rockets are smaller rockets that typically only carry a few instruments and take short flights into space—usually only 15 minutes. Crucially, sounding rockets fly above most of Earth’s atmosphere, allowing instruments on board to to see the ultraviolet wavelengths measured by AIA. These wavelengths of light are absorbed by Earth’s atmosphere and can’t be measured from the ground. To calibrate AIA, they would attach an ultraviolet telescope to a sounding rocket and compare that data to the measurements from AIA. Scientists can then make adjustments to account for any changes in AIA’s data.

There are some drawbacks to the sounding rocket method of calibration. Sounding rockets can only launch so often, but AIA is constantly looking at the Sun. That means there’s downtime where the calibration is slightly off in between each sounding rocket calibration. Dr. Luiz Dos Santos, a solar physicist at NASA’s Goddard Space Flight Center in Greenbelt, Maryland said:

“It’s also important for deep space missions, which won’t have the option of sounding rocket calibration. We’re tackling two problems at once.”

Researchers needed to train a machine learning algorithm to recognize solar structures and how to compare them using AIA data. To do this, they give the algorithm images from sounding rocket calibration flights and tell it the correct amount of calibration they need. After enough of these examples, they give the algorithm similar images and see if it would identify the correct calibration needed. With enough data, the algorithm learns to identify how much calibration is needed for each image.

Because AIA looks at the Sun in multiple wavelengths of light, researchers can also use the algorithm to compare specific structures across the wavelengths and strengthen its assessments.

Machine learning beyond the Sun

Researchers have also been using machine learning to better understand conditions closer to home.

As machine learning advances, its scientific applications will expand to more and more missions. For the future, this may mean that deep space missions—which travel to places where calibration rocket flights aren’t possible—can still be calibrated and continue giving accurate data, even when getting out to greater and greater distances from Earth or any stars.
