“Why will 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 together with 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 entails collaboration between NASA scientists, medical doctors and researchers, alongside the US federal authorities, all of whom purpose to chop nationwide most cancers charges by a minimum of 50% over the subsequent 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 demise sentence, we stop most cancers earlier than it begins, we catch most cancers early so folks dwell 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 demise worldwide, with nearly 20 million new instances and 9.7 million cancer-related deaths reported in 2022 alone, in line with the Nationwide Most cancers Institute (NCI) — and these numbers are solely anticipated to rise.

Compounding the difficulty is the truth that not all cancers are created equal — solely a handful have well-vetted, early-detection protocols, to not point out therapy choices and promising survival charges. Breast most cancers, for instance, has an nearly 90% 5 yr survival fee whereas lung most cancers, liver most cancers, colon and rectal most cancers (the latter of which is presently on the rise by way of analysis), have poorer outcomes.
NASA scientists are uniquely positioned to assist discover how most cancers cells develop, operate, and reply to therapy, mentioned Nelson. Testing tumors exterior the physique isn’t a brand new idea, however cells behave otherwise in house underneath microgravity. On this surroundings, cells change into extremely harassed, inflicting them to age extra quickly and, when cancerous, progress illness extra shortly than on Earth.
“Cells develop otherwise,” mentioned Nelson. “Tumors develop otherwise. Tissues can kind otherwise, […] and meaning medicines could be examined otherwise.”
Many experiments are carried out on the Worldwide Area Station (ISS), for that matter, which accommodates the world’s most subtle microgravity laboratory. And a few of these experiments are notably centered on most cancers analysis.
“Astronauts and groups on Earth carry out groundbreaking analysis day by day, and since November of 2000, we have had nearly 4,000 totally 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 Area Heart, on the briefing.
In truth, 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 be aware of a selected success involving a widely known anti-cancer drug named Keytruda made attainable by 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 best method — to get it to succeed in a exact goal within the physique,” he defined. “[We] have been in a position to develop strategies of protein crystal development that made it attainable to manage Keytruda [on Earth] in a brand new method, by an IV injection.”
Keytruda beforehand required a number of hours to manage, which places a burden on sufferers and healthcare programs. “However in creating the drug for an IV infusion, [it can now] be administered by a physician in as little as 20 minutes,” he mentioned. In collaboration with the pharmaceutical firm Merck, the group is now awaiting approval of the subsequent step for Keytruda: a fast injection.
NASA scientists are additionally working to develop extra subtle most cancers cell detection strategies, that are being integrated into the astronaut well being surveillance program to identify sure cancers earlier and make these measures extra broadly obtainable.
“What we have realized partially by these centered matter areas and protein crystal development, nanoparticle drug supply, and stem cell analysis, is that these voyages of discovery aren’t 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,” mentioned Michael Roberts, chief scientific officer of the Worldwide Area Station Nationwide Laboratory and vice chairman on the Heart for the Development of Science in Area 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 keep in mind, we’re NASA. We do moonshots.”
