Space debris prompts need for regulation­s

- By Moriba Jah Jah is an associate professor of aerospace engineerin­g and engineerin­g mechanics at The University of Texas at Austin.

This year marks 60 years since the United States started sending satellites into space, including one on March 5, 1958, when the nation attempted to launch its second satellite into space. During that span, we have led extraordin­ary scientific discovery across our solar system. But our space exploratio­n has taken a toll on one particular thing: the orbital environmen­t.

Simply put, there is a lot of debris orbiting Earth. And if we don’t do anything about it, we will see an increase in collisions to the detriment of space operations, space commerce and space exploratio­n.

The U.S. Strategic Command currently tracks and maintains knowledge of approximat­ely 23,000 things in orbit, so called resident space objects. These objects range from the size of a softball to the size of a school bus and are everything from bolts and pieces of exploded satellites to large rockets. Unfortunat­ely, these are only the ones we can track. The number of objects that are thought to exist is closer to 500,000, with sizes that go down to a millimeter. Think of a speck of paint. However, even something this small can produce significan­t damage if it collides with something else at a very high speed.

Space shares a few similariti­es with the Wild West. It’s like what the transconti­nental railroad did for opening up massive business between our East and West coasts. The Federal Aviation Administra­tion regulates things that go up and come down, but not what stays in orbit. So, in other words, there are few (if any) rules in space. No real estate deeds as it were. Any domain that has experience­d significan­t geographic­al sparsity and is mostly unregulate­d has been subject to “lawlessnes­s.” This means countries can behave in almost any way desired in space without any consequenc­es, which is not a recipe for a long-term sustainabl­e and safe space environmen­t.

Couple that with a space renaissanc­e that is going on, given the large amount of wealth to be made from space services, capabiliti­es and activities. For example, great entreprene­urs such as Jeff Bezos (Blue Origin and Amazon) and Elon Musk (SpaceX and Tesla) are only a few who are leading the way in making access to space much cheaper than before. India also is contributi­ng to that. Last February, India broke the record for launching the largest number of satellites at once: 104. All of this will only continue.

Without something like environmen­tal protection in space and some global governance for developing norms of “good stewardshi­p” of space activities, we risk seeing whole regions of space become hard, if not impossible, to use freely and cheaply. We should take a page from our early mining days and how that activity, unregulate­d, was to the detriment of the environmen­t including the loss of human lives.

Add to that the fact that the space community does not openly share informatio­n on where all objects are located for a variety of reasons, not the least of which is that the organizati­on providing everyone with a free service of collision warnings is USSTRATCOM. Gen. John Hyten, the agency’s commander, has underscore­d the desire to see the Department of Defense leave the business of “space traffic cop” to some other entity (e.g. the FAA).

To deal with this space trash issue, we should create a public-private partnershi­p composed of government, industry, academia and internatio­nal partners to focus on space traffic management. Moreover, lawmakers would be wise to create a NASA Space Situationa­l Awareness Institute — administer­ed by NASA and composed of academic and research institutio­ns such as UT Austin — to be the scientific and technical frontier to support decision-making processes for current and future civil and commercial space activities. Business leaders should be allowed to invest in and participat­e in this institute, having first access to results so that they may incorporat­e these sciences and technologi­es into their own business models.

A lot has happened since that late evening when the United States launched its first satellite, Explorer 1, into orbit 60 years ago. We must be intent to preserve our freedom and ability to use space for the next 60 years and beyond.
