According to Bill Nye, known to most as "The Science Guy" but who now leads the largest non-government space exploration nonprofit, humanity has always asked two questions: How did we get here and are we alone.

"If you want to answer those two questions, you've got to explore space," Nye, CEO of The Planetary Society, says in his keynote address at Houston's annual SpaceCom.

The conference, which took over downtown Houston's George R. Brown Convention Center for November 20 and 21, welcomed a record number of attendees from all over the world. Throughout the two days, 2,500 space fans, experts, and professionals from around the world engaged with panels and programming as well as the exhibit hall full of dozens of space companies.

In his keynote address, Nye walked through the history of solar space studies and breakthroughs, from Johannes Kepler's 17th century observation of the sun's solar force on comets to Carl Sagan's work to develop a completely solar powered spacecraft. Sagan, who was a mentor to Nye, passed away in 1996 and didn't get to see his dream become reality.

Nye, however, has accomplished Sagan's goals, and the technology he and The Planetary Society has developed is low cost and completely citizen funded, representing a huge step toward democratizing space.

"We built two spacecrafts for $7 million," Nye says of LightSail 1 and 2.

The first iteration didn't last long, but LightSail 2 equipped with CubeSats — small but mighty satellites — became the first controlled solar sail spacecraft completely propelled by the sun. Solar sails use radiation pressure from the sun as an energy source reacting with extremely thin reflective material that makes up the sail.

The device, which is still in space, represents a lot of potential for long-term space missions since no fuel is needed. While there have been light sails launched in the past, LightSail 2 was the first iteration to be able to be steered from earth in a timely manner. (The device can be turned in a matter of minutes.)

"With this technology, we can democratize space," Nye tells the crowd, sharing that just a few hours before, Time magazine named the technology as the most innovative invention in aerospace.

Nye says that while the work he is doing at The Planetary Society came about as a group of engineers trying to solve a specific problem, the results they have found and the feedback they received represent the world's interest in continuing space exploration in a cost-effective and feasible way.

"Space brings people together," Nye says.

Axiom Space-tested cancer drug advances to clinical trials

mission critical

A cancer-fighting drug tested aboard several Axiom Space missions is moving forward to clinical trials.

Rebecsinib, which targets a cancer cloning and immune evasion gene, ADAR1, has received FDA approval to enter clinical trials under active Investigational New Drug (IND) status, according to a news release. The drug was tested aboard Axiom Mission 2 (Ax-2) and Axiom Mission 3 (Ax-3). It was developed by Aspera Biomedicine, led by Dr. Catriona Jamieson, director of the UC San Diego Sanford Stem Cell Institute (SSCI).

The San Diego-based Aspera team and Houston-based Axiom partnered to allow Rebecsinib to be tested in microgravity. Tumors have been shown to grow more rapidly in microgravity and even mimic how aggressive cancers can develop in patients.

“In terms of tumor growth, we see a doubling in growth of these little mini-tumors in just 10 days,” Jamieson explained in the release.

Rebecsinib took part in the patient-derived tumor organoid testing aboard the International Space Station. Similar testing is planned to continue on Axiom Station, the company's commercial space station that's currently under development.

Additionally, the drug will be tested aboard Ax-4 under its active IND status, which was targeted to launch June 25.

“We anticipate that this monumental mission will inform the expanded development of the first ADAR1 inhibitory cancer stem cell targeting drug for a broad array of cancers," Jamieson added.

According to Axiom, the milestone represents the potential for commercial space collaborations.

“We’re proud to work with Aspera Biomedicines and the UC San Diego Sanford Stem Cell Institute, as together we have achieved a historic milestone, and we’re even more excited for what’s to come,” Tejpaul Bhatia, the new CEO of Axiom Space, said in the release. “This is how we crack the code of the space economy – uniting public and private partners to turn microgravity into a launchpad for breakthroughs.”

Chevron enters the lithium market with major Texas land acquisition

to market

Chevron U.S.A., a subsidiary of Houston-based energy company Chevron, has taken its first big step toward establishing a commercial-scale lithium business.

Chevron acquired leaseholds totaling about 125,000 acres in Northeast Texas and southwest Arkansas from TerraVolta Resources and East Texas Natural Resources. The acreage contains a high amount of lithium, which Chevron plans to extract from brines produced from the subsurface.

Lithium-ion batteries are used in an array of technologies, such as smartwatches, e-bikes, pacemakers, and batteries for electric vehicles, according to Chevron. The International Energy Agency estimates lithium demand could grow more than 400 percent by 2040.

“This acquisition represents a strategic investment to support energy manufacturing and expand U.S.-based critical mineral supplies,” Jeff Gustavson, president of Chevron New Energies, said in a news release. “Establishing domestic and resilient lithium supply chains is essential not only to maintaining U.S. energy leadership but also to meeting the growing demand from customers.”

Rania Yacoub, corporate business development manager at Chevron New Energies, said that amid heightening demand, lithium is “one of the world’s most sought-after natural resources.”

“Chevron is looking to help meet that demand and drive U.S. energy competitiveness by sourcing lithium domestically,” Yacoub said.
