“Why can we go to house?” requested NASA administrator Invoice Nelson to a small crowd at NASA headquarters final week. “We go to discover the heavens, however we additionally go to enhance life right here on Earth, and that features attacking this dreaded illness that we all know is most cancers.”
Nelson was talking at an occasion held at the side of the U.S. Division of Well being and Human Companies (HHS) to present an replace on progress that the respective businesses are making towards the White Home’s Most cancers Moonshot initiative, initially launched in 2016.
This system includes collaboration between NASA scientists, docs and researchers, alongside the US federal authorities, all of whom goal to chop nationwide most cancers charges by no less than 50% over the following 25 years. Acknowledged on the White Home web site, “We’re constructing a world the place the phrase ‘most cancers’ loses its energy, a analysis isn’t a loss of life sentence, we stop most cancers earlier than it begins, we catch most cancers early so folks reside longer and more healthy lives, and sufferers and households don’t should navigate their most cancers journey alone.”
That is an formidable purpose. Most cancers is among the many main causes of loss of life worldwide, with nearly 20 million new instances and 9.7 million cancer-related deaths reported in 2022 alone, in accordance with the Nationwide Most cancers Institute (NCI) — and these numbers are solely anticipated to rise.

Compounding the problem is the truth that not all cancers are created equal — solely a handful have well-vetted, early-detection protocols, to not point out remedy choices and promising survival charges. Breast most cancers, for instance, has an nearly 90% 5 yr survival charge whereas lung most cancers, liver most cancers, colon and rectal most cancers (the latter of which is at the moment on the rise when it comes to analysis), have poorer outcomes.
NASA scientists are uniquely positioned to assist discover how most cancers cells develop, perform, and reply to remedy, stated Nelson. Testing tumors exterior the physique isn’t a brand new idea, however cells behave otherwise in house underneath microgravity. On this surroundings, cells turn into extremely burdened, inflicting them to age extra quickly and, when cancerous, progress illness extra shortly than on Earth.
“Cells develop otherwise,” stated Nelson. “Tumors develop otherwise. Tissues can type otherwise, […] and meaning medicines may be examined otherwise.”
Many experiments are performed on the Worldwide House Station (ISS), for that matter, which comprises the world’s most subtle microgravity laboratory. And a few of these experiments are significantly targeted on most cancers analysis.
“Astronauts and groups on Earth carry out groundbreaking analysis every single day, and since November of 2000, we have had nearly 4,000 completely different experiments representing greater than 5,000 researchers from over 100 international locations,” acknowledged Jenny Turner, a consultant of the house station’s analysis Integration Workplace at NASA Johnson House Middle, on the briefing.
The truth is, thrilling progress has just lately been made in areas together with protein crystallization , nanoparticle drug supply, tissue engineering, and stem cell analysis. These discoveries have allowed scientists to check and create higher medication whereas additionally minimizing the necessity for animal testing.
Nelson additionally made word of a specific success involving a well known anti-cancer drug named Keytruda made potential via a gamut of ISS-based discoveries. “It is one factor to develop a drug or therapeutic, nevertheless it’s one other to ensure that [it] is run in the simplest means — to get it to achieve a exact goal within the physique,” he defined. “[We] had been in a position to develop strategies of protein crystal development that made it potential to manage Keytruda [on Earth] in a brand new means, by an IV injection.”
Keytruda beforehand required a number of hours to manage, which places a burden on sufferers and healthcare methods. “However in growing the drug for an IV infusion, [it can now] be administered by a health care provider in as little as 20 minutes,” he stated. In collaboration with the pharmaceutical firm Merck, the staff is now awaiting approval of the following step for Keytruda: a fast injection.
NASA scientists are additionally working to develop extra subtle most cancers cell detection strategies, that are being included into the astronaut well being surveillance program to identify sure cancers earlier and make these measures extra broadly out there.
“What we have discovered partly via these targeted matter areas and protein crystal development, nanoparticle drug supply, and stem cell analysis, is that these voyages of discovery are usually not solely about people trying outward to discover new worlds and new locations exterior of Earth, however actual world enhancements in our understanding of illness right here on Earth,” stated Michael Roberts, chief scientific officer of the Worldwide House Station Nationwide Laboratory and vp on the Middle for the Development of Science in House for instances, which manages the ISS Nationwide Lab.
“If beating most cancers sounds nice, if it sounds daring, if it sounds even not possible,” added Nelson. “Simply bear in mind, we’re NASA. We do moonshots.”
