Earlier today, NASA’s Tandem Reconnection and Cusp Electrodynamics Reconnaissance Satellites (TRACER) twin satellites were successfully launched from Vandenberg Space Force Station in California.

The TRACER mission’s goal is to study magnetic reconnection and its effects in Earth’s atmosphere. Magnetic reconnection is the interplay between solar winds and the Earth’s magnetic field.

The two satellites, each about the size of a washing machine, will be in orbit over both the North and South poles for the next 12 months taking measurements.

In this interview, David Miles, TRACERS Principal Investigator at the University of Iowa, answers a number of questions about the current mission, including:

  • Can you explain what space weather is?
  • Why was this mission designed to have two spacecraft instead of just one?
  • Why is understanding space weather important for protecting our astronauts as well as technology in space and on the ground?

You can learn even more about the mission from this NASA fact sheet.

It is encouraging to see scientific missions underway to better understand outside influences on our upper atmosphere. Let’s hope we can also maintain and expand on space missions that help us understand man-made influences on our atmosphere. Closing our eyes for political reasons is never a good idea.

Space Quote: The NASA Voyager Declaration

Posted on by onespaceman2000

“We dissent to implementing indiscriminate cuts to NASA science and aeronautics research because this will leave the American people without the unique public good that NASA provides. Basic research in space science, aeronautics, and the stewardship of the Earth are inherently governmental functions that cannot and will not be taken up by the private sector. Furthermore, NASA has a nearly threefold return on investment in economic activity, and supports national security by ensuring the United States maintains its lead in science and technology.”

-Just one of many points in a letter to NASA’s Interim Administrator Sean Duffy from more than 300 current and former NASA employees, labeled as the NASA Voyager Declaration. Probably employees from every federal agency could issue a similar appeal (okay, maybe not the ICE employees) given the unwarranted and poorly-targeted cuts wiping out science-driven programs. We need such statements to remember what is important about these programs, and how petty politics will diminish our nation. It’s been quite a few years since a German priest nailed a statement to a church door highlighting great abuses by Church authorities. Sometimes history rhymes.

Space Stories: Watching a Newborn Planet, Investigating a Cosmic Fossil, and TRACERS to Study Magnetic Fields

Here are some recent space-related stories of interest.

—European Southern Observatory: “Astronomers Witness Newborn Planet Sculpting the Dust Around It“

Astronomers may have caught a still-forming planet in action, carving out an intricate pattern in the gas and dust that surrounds its young host star. Using ESO’s Very Large Telescope (VLT), they observed a planetary disc with prominent spiral arms, finding clear signs of a planet nestled in its inner regions. This is the first time astronomers have detected a planet candidate embedded inside a disc spiral. “We will never witness the formation of Earth, but here, around a young star 440 light-years away, we may be watching a planet come into existence in real time,” says Francesco Maio, a doctoral researcher at the University of Florence, Italy, and lead author of this study, published today in Astronomy & Astrophysics.

—Space.com: “Astronomers Discover a Cosmic ‘Fossil’ at the Edge of Our Solar System. Is this Bad News for ‘Planet 9’?“

Astronomers have discovered a massive new solar system body located beyond the orbit of Pluto. The weird elongated orbit of the object suggests that if “Planet Nine” exists, it is much further from the sun than thought, or it has been ejected from our planetary system altogether. The strange orbit of the object, designated 2023 KQ14 and nicknamed “Ammonite,” classifies it as a “sednoid.” Sednoids are bodies beyond the orbit of the ice giant Neptune, known as trans-Neptunian objects (TNOs), characterized by a highly eccentric (non-circular) orbit and a distant closest approach to the sun or “perihelion.”

—Southwest Research Institute: “TRACERS Mission Prepares for Launch“

NASA’s Tandem Reconnection and Cusp Electrodynamics Reconnaissance Satellites (TRACERS) mission, a collaborative effort led by the University of Iowa (UI) with substantial contributions from Southwest Research Institute (SwRI), has entered its final integration phase. NASA is set to launch TRACERS’ two satellites into low Earth orbit on July 22, 2025, from Vandenberg Space Force Base in California. The TRACERS mission will explore the dynamic interactions between the Sun’s and Earth’s magnetic fields.

A Day in Astronomy: “The Eagle Has Landed”

On this day in 1969, the statement “The Eagle has landed” changed the history of mankind as humans arrived on the surface of the Moon.

Spoken by Apollo 11 astronaut Neil Armstrong, the “Eagle” referred to the Lunar Module Eagle as it touched down on the Moon’s Sea of Tranquility. Four hours later, and almost 110 hours after being launched from Earth, Armstrong stepped onto the Moon, stating “That’s one small step for a man, one giant leap for mankind.”

The crew on Apollo 11 consisted of Neil Armstrong (Commander), Edwin E. “Buzz” Aldrin Jr. (Lunar Module Pilot), and Michael Collins (Command Module Pilot).

Space Quote: The Terra-forming Will Continue, But Don’t Ask for Data

“They simply don’t want the public to see the meticulously assembled and scientifically validated information about what climate change is already doing to our farms, forests, and fisheries, as well as to storms, floods, wildfires, and coast property — and about how all those damages will grow in the absence of concerted remedial action.”

–Statement by climate scientist Katharine Hayhoe, chief scientist at The Nature Conservancy, regarding NASA’s removal of national climate assessments from its website. Of course, the daily news about floods and fires will continue to keep us aware of ongoing terra-forming here on planet Earth. You can also find information about the last National Climate Assessment at this USDA site, for now at least.
