NASA has asked the US aerospace industry how it would go about “maximizing the long-term efficiency and sustainability” of the Space Launch System rocket and its associated ground systems.

The request comes as NASA and its chief contractor for the rocket, Boeing, are nearing the launch pad after a long, arduous, and expensive development process that has lasted more than a decade. The heavy lift SLS rocket, carrying an Orion space capsule, should finally make its debut during the first half of 2022.

In its request NASA says it would like to fly the SLS rocket for “30 years or more” as a national capability. Moreover, the agency wants the rocket to become a “sustainable and affordable system for moving humans and large cargo payloads to cislunar and deep-space destinations.”

Ships From 1,581 Ports May Go to Antarctica, Bringing Unwanted Guests

Right now, the Antarctic and the waters around it are surprisingly free of invasive species. According to new research, however, that situation might change in the not-too-distant future, thanks to a shocking level of connectivity with ports across the world. Ships can accidentally carry a large array of marine life, which can in turn colonize new places (like the world’s polar south), outcompete native life, and generally wreak havoc on an ecosystem. New research has traced the paths of the various research vessels, tourist ships, and fishing boats that chug along through the icy waters of the Antarctic.

According to Arlie McCarthy, a researcher in the University of Cambridge’s Department of Zoology and the British Antarctic Survey, these watercraft all carry with them a risk of unwanted visitors. And the visitors may have more chances to relocate than we once thought.

“We know from other cold areas in the world, including the Arctic, that things growing on the hulls of ships absolutely do get transported from place to place, and it is one of the major sources of marine introductions around the world,” McCarthy told Ars. “We also know that ships going into Antarctica do have things growing on them. What we didn’t know until this point was good detail on where those ships go.”
