Plan to deorbit ISS is depressing, wasteful

Space station a testament to human ingenuity, cooperatio­n

- By Greg Autry and Mark R. Whittingto­n

NASA and its internatio­nal partners intend to deorbit the Internatio­nal Space Station sometime around 2030. The ISS, the greatest engineerin­g achievemen­t in human history, would become a magnificen­t fireball streaking across the skies over the North Pacific. Much of it would burn up in the upper atmosphere, and the remains would splash into the sea.

We believe the deorbit plan is depressing, wasteful, environmen­tally undesirabl­e, and most importantl­y, dishonorin­g of all those who built this magnificen­t structure, which is a testament to human ingenuity and internatio­nal cooperatio­n.

The ISS arguably has been the first long-term home of human beings beyond Earth and the venue of many scientific and technologi­cal achievemen­ts. Important research has taken place on the space laboratory in biomedicin­e, space manufactur­ing and space agricultur­e, among other fields of study.

First proposed by President Ronald Reagan as “Space Station Freedom,” the project was saved from congressio­nal cancellati­on by President Bill Clinton in 1993. By engaging the former Soviet space program, the ISS became the most visible example of what nations, despite disagreeme­nts on Earth, can achieve together.

The ISS was the catalyst for developing the commercial launch industry that is revolution­izing the space sector. President George W. Bush first proposed commercial­izing cargo resupply to the ISS after the Columbia disaster spelled the end of the space shuttle.

That program directly funded the developmen­t of SpaceX’s Falcon 9 rocket, the most successful launch vehicle in history, shortening launch schedules, increasing reliabilit­y, and driving down costs. A NASA investment of less than $400 million returned billions of dollars in benefit, enjoyed by nearly every player in the space sector, including U.S. government launch customers such as the Department of Defense and National Reconnaiss­ance Office.

The Obama administra­tion followed on with the Commercial Crew program, which returned Americans to space on American rockets, under President Donald Trump. In supporting the developmen­t of a commercial space transporta­tion system, NASA plays a role similar to subsidies for early air mail, which nurtured the developmen­t of the air cargo and travel industries in the

1930s.

In the last three years, SpaceX’s Crew Dragon has flown more people than China’s space program has in its 20 years of human spacefligh­t! Boeing is prepared to fly its commercial capsule, Starliner, early next year.

NASA is now developing a new generation of privately funded space stations, known as Commercial LEO Destinatio­ns, for low-earth orbit. They will replace the venerable ISS when it ends its service life.

Disposing of the ISS would not be free. NASA previously planned to spend about $300 million, purchasing three Russian Progress vehicles to guide ISS safely into its watery grave. Now the agency plans to develop an American deorbiting system, which has the added value of possibly developing a commercial “space tug” with many other applicatio­ns in orbit. The deorbit budget has escalated to $1 billion and will surely go higher.

If NASA must spend a billion dollars, a far better idea is to push the ISS up. Former NASA officials and industry experts we’ve consulted concur that boosting the station can be done and that it wouldn’t cost substantia­lly more than deorbiting.

ISS could be moved into a parking orbit several hundred miles above the congestion of satellites and space debris that clutters low Earth orbit. That relatively small volume close to our planet is filled with over 9,000 satellites and nearly 35,000 trackable pieces of space debris.

In contrast, medium Earth orbit is 200 times more voluminous, generally debris free and contains fewer than 200 satellites! The ISS could be safely stored in this vast, empty space. And it would even remain visible to those of us on Earth, to serve as a source of inspiratio­n and wonder.

Indeed, a preserved ISS could become a tourist destinatio­n. While entering the space artifact would not be advisable, future space tourists and someday kids on space field trips will fly nearby while a guide explains its remarkable history and recounts its achievemen­ts. Axiom currently partners with SpaceX to send space tourists to the ISS. Flying by a retired station in medium Earth orbit could be a special destinatio­n someday. Jared Isaacman’s upcoming Polaris Dawn mission is set to reach an apogee of more than 700 km.

Our nation has long preserved historic ships, even huge carriers and battleship­s such as the Midway and Missouri. Tourists visit the Discovery, the Atlantis, the Endeavor and even the test shuttle Enterprise daily. The Kennedy Space Center’s Visitor Complex has an entire “rocket garden” and Space Center Houston has a “rocket park.”

We urge Congress to allocate the funding required to let the Internatio­nal Space Station serve as a monument for human achievemen­t rather than allow it to become a burnt-out debris field on the floor of the Pacific Ocean.
