The Apollo 11 mission in July 1969 completed the goal set by President John F. Kennedy in 1961 to land a man on the Moon and return him safely to the Earth before the end of the decade. At the time, NASA planned nine more Apollo Moon landing missions of increasing complexity and an Earth orbiting experimental space station. No firm human space flight plans existed once these missions ended in the mid-1970s. After taking office in 1969, President Richard M. Nixon chartered a Space Task Group (STG) to formulate plans for the nation’s space program for the coming decades. The STG’s proposals proved overly ambitious and costly to the fiscally conservative President who chose to take no action on them.

On May 25, 1961, before a Joint Session of Congress, President John F. Kennedy committed the United States to the goal, before the decade was out, of landing a man on the Moon and returning him safely to the Earth. President Kennedy reaffirmed the commitment during an address at Rice University in Houston in September 1962. Vice President Lyndon B. Johnson, who played a leading role in establishing NASA in 1958, under Kennedy served as the Chair of the National Aeronautics and Space Council. Johnson worked with his colleagues in Congress to ensure adequate funding for the next several years to provide NASA with the needed resources to meet that goal.
Following Kennedy’s assassination in November 1963, now President Johnson continued his strong support to ensure that his predecessor’s goal of a Moon landing could be achieved by the stipulated deadline. But with increasing competition for scarce federal resources from the conflict in southeast Asia and from domestic programs, Johnson showed less interest in any space endeavors to follow the Apollo Moon landings. NASA’s annual budget peaked in 1966 and began a steady decline three years before the agency met Kennedy’s goal. From a budgetary standpoint, the prospects of a vibrant, post-Apollo space program didn’t look all that rosy, the triumphs of the Apollo missions of 1968 and 1969 notwithstanding.

Less than a month after assuming the Presidency in January 1969, Richard M. Nixon appointed a Space Task Group (STG), led by Vice President Spiro T. Agnew as the Chair of the National Aeronautics and Space Council, to report back to him on options for the American space program in the post-Apollo years. Members of the STG included NASA Acting Administrator Thomas O. Paine (confirmed by the Senate as administrator on March 20), the Secretary of Defense, and the Director of the Office of Science and Technology. At the time, the only approved human space flight programs included lunar landing missions through Apollo 20 and three long-duration missions to an experimental space station based on Apollo technology that evolved into Skylab.
Beyond a general vague consensus that the United States human space flight program should continue, no approved projects existed once these missions ended by about 1975. With NASA’s intense focus on achieving the Moon landing within President Kennedy’s time frame, long-term planning for what might follow the Apollo Program garnered little attention. During a Jan. 27, 1969, meeting at NASA chaired by Acting Administrator Paine, a general consensus emerged that the next step after the Moon landing should involve the development of a 12-person earth-orbiting space station by 1975, followed by an even larger outpost capable of housing up to 100 people “with a multiplicity of capabilities.” In June, with the goal of the Moon landing almost at hand, NASA’s internal planning added the development of a space shuttle by 1977 to support the space station, the development of a lunar base by 1976, and the highly ambitious idea that the U.S. should prepare for a human mission to Mars as early as the 1980s. NASA presented these proposals to the STG for consideration in early July in a report titled “America’s Next Decades in Space.”

Still bathing in the afterglow of the successful Moon landing, the STG presented its 29-page report “The Post-Apollo Space Program: Directions for the Future” to President Nixon on Sep. 15, 1969, during a meeting at the White House. In its Conclusions and Recommendations section, the report noted that the United States should pursue a balanced robotic and human space program but emphasized the importance of the latter, with a long-term goal of a human mission to Mars before the end of the 20th century. The report proposed that NASA develop new systems and technologies that emphasized commonality, reusability, and economy in its future programs. To accomplish these overall objectives, the report presented three options:
Option I – this option required more than a doubling of NASA’s budget by 1980 to enable a human Mars mission in the 1980s, establishment of a lunar orbiting space station, a 50-person Earth orbiting space station, and a lunar base. The option required a decision by 1971 on development of an Earth-to-orbit transportation system to support the space station. The option maintained a strong robotic scientific and exploration program.
Option II – this option maintained NASA’s budget at then current levels for a few years, then anticipated a gradual increase to support the parallel development of both an earth orbiting space station and an Earth-to-orbit transportation system, but deferred a Mars mission to about 1986. The option maintained a strong robotic scientific and exploration program, but smaller than in Option I.
Option III – essentially the same as Option II but deferred indefinitely the human Mars mission.
In separate letters, both Agnew and Paine recommended to President Nixon to choose Option II.

The White House released the report to the public at a press conference on Sep. 17 with Vice President Agnew and Administrator Paine in attendance. Although he publicly supported a strong human spaceflight program, enjoyed the positive press he received when photographed with Apollo astronauts, and initially sounded positive about the STG options, President Nixon ultimately chose not to act on the report’s recommendations. Nixon considered these plans too grandiose and far too expensive and relegated NASA to one America’s domestic programs without the special status it enjoyed during the 1960s. Even some of the already planned remaining Moon landing missions fell victim to the budgetary axe.
On Jan. 4, 1970, NASA had to cancel Apollo 20 since the Skylab program needed its Saturn V rocket to launch the orbital workshop. In 1968, then NASA Administrator James E. Webb had turned off the Saturn V assembly line and none remained beyond the original 15 built under contract. In September 1970, reductions in NASA’s budget forced the cancellation of two more Apollo missions, and in 1971 President Nixon considered cancelling two more. He reversed himself and they flew as Apollo 16 and Apollo 17 in 1972, the final Apollo Moon landing missions.

More than two years after the STG submitted its report, in January 1972 President Nixon directed NASA Administrator James C. Fletcher to develop the Space Transportation System, the formal name for the space shuttle, the only element of the recommendations to survive the budgetary challenges. NASA anticipated the first orbital flight of the program in 1979, with the actual first flight occurring two years later. Twelve years elapsed after Nixon’s shuttle decision when President Ronald W. Reagan approved the development of a space station, the second major component of the STG recommendation. 14 years later, the first element of that program reached orbit. In those intervening years, NASA had redesigned the original American space station, leading to the development of a multinational orbiting laboratory called the International Space Station. Humans have inhabited the space station continuously for the past quarter century, conducting world class and cutting edge scientific and engineering research. Work on the space station helps enable future programs, returning humans to the Moon and later sending them on to Mars and other destinations.

Earlier this month, nine small businesses received 2023 NASA Small Business Innovation Research (SBIR) Ignite Phase II awards to further develop technologies that may be used in the agency’s missions and in the commercial space industry.
The SBIR Ignite Phase II awardees, who will receive up to $850,000 to fund their projects, are developing technology capabilities in the detection of wildfires, support for water management in agriculture, in-space debris detection, mineral mining from lunar regolith, in-space production, and more. These capabilities are vital to supporting deep space exploration, low Earth orbit missions, and preserving life on our home planet for the benefit of all. The businesses initially were selected for Phase I awards in 2023 and provided six months and up to $150,000 to prove their concepts before competing for Phase II.
“We want to support innovators across the aerospace industry because their technologies have the potential to make a big impact in the commercial market. A rich and diverse marketplace creates more opportunity for us all. These Phase II awards illuminate a clear path for a unique range of technologies that we believe will positively influence the lives of all Americans.”
Jason L. Kessler
NASA SBIR/STTR Program Executive
The SBIR Ignite pilot initiative supports product-driven small businesses, startups, and entrepreneurs that have commercialization at the forefront of their innovation strategies and processes but that are not targeting NASA as a primary customer. The pilot initiative provides funding and other support to mitigate risk in technologies that have strong commercial potential by offering lower barriers to entry, a streamlined review and selection process, and accelerated technology development and awards as compared to the NASA SBIR program’s main solicitation. It also focuses on helping make participating companies more appealing to investors, customers, and partners, while fulfilling SBIR’s mission of increasing commercialization of innovations derived from federal research and development.
While the agency’s main Small Business Innovation Research and Small Business Technology Transfer solicitations focus on technologies with potential for infusion in both NASA missions and commercialization in the marketplace, the SBIR Ignite opportunity is less prescriptive and focuses on topics that are relevant to emerging commercial markets in aerospace, such as accelerating in-space production applications in low Earth orbit.
The awarded companies are:
Astral Forge, LLC, Palo Alto, California Astrobotic Technology Inc., Pittsburgh Benchmark Space Systems, Burlington, Vermont Brayton Energy, LLC, Hampton, New Hampshire Channel-Logistics LLC dba Space-Eyes, Miami GeoVisual Analytics, Westminster, Colorado Space Lab Technologies, LLC, Boulder, Colorado Space Tango, Lexington, Kentucky VerdeGo Aero, De Leon Springs, Florida
The third year of NASA Small Business Innovation Research (SBIR) Ignite is underway, as the 2024 SBIR Ignite Phase I solicitation closed on July 30, 2024. Those selections are expected to be announced Fall 2024.
NASA’s Small Business Innovation Research and Small Business Technology Transfer program is part of NASA’s Space Technology Mission Directorate and is managed by NASA’s Ames Research Center in Silicon Valley.

6 Min Read NASA Discovers a Long-Sought Global Electric Field on Earth

A rocket team reports the first successful detection of Earth’s ambipolar electric field: a weak, planet-wide electric field as fundamental as Earth’s gravity and magnetic fields. First hypothesized more than 60 years ago, the ambipolar electric field is a key driver of the “polar wind,” a steady outflow of charged particles into space that occurs above Earth’s poles. This electric field lifts charged particles in our upper atmosphere to greater heights than they would otherwise reach and may have shaped our planet’s evolution in ways yet to be explored.
Using observations from a NASA suborbital rocket, an international team of scientists has, for the first time, successfully measured a planet-wide electric field thought to be as fundamental to Earth as its gravity and magnetic fields. Known as the ambipolar electric field, scientists first hypothesized over 60 years ago that it drove how our planet’s atmosphere can escape above Earth’s North and South Poles. Measurements from the rocket, NASA’s Endurance mission, have confirmed the existence of the ambipolar field and quantified its strength, revealing its role in driving atmospheric escape and shaping our ionosphere — a layer of the upper atmosphere — more broadly.
Understanding the complex movements and evolution of our planet’s atmosphere provides clues not only to the history of Earth but also gives us insight into the mysteries of other planets and determining which ones might be hospitable to life. The paper was published Wednesday, Aug. 28, 2024, in the journal Nature.

Since the late 1960s, spacecraft flying over Earth’s poles have detected a stream of particles flowing from our atmosphere into space. Theorists predicted this outflow, which they dubbed the “polar wind,” spurring research to understand its causes.
Some amount of outflow from our atmosphere was expected. Intense, unfiltered sunlight should cause some particles from our air to escape into space, like steam evaporating from a pot of water. But the observed polar wind was more mysterious. Many particles within it were cold, with no signs they had been heated — yet they were traveling at supersonic speeds.
“Something had to be drawing these particles out of the atmosphere,” said Glyn Collinson, principal investigator of Endurance at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, and lead author of the paper. Scientists suspected a yet-to-be-discovered electric field could be at work.
The hypothesized electric field, generated at the subatomic scale, was expected to be incredibly weak, with its effects felt only over hundreds of miles. For decades, detecting it was beyond the limits of existing technology. In 2016, Collinson and his team got to work inventing a new instrument they thought was up to the task of measuring Earth’s ambipolar field.
Launching a Rocket from the Arctic
The team’s instruments and ideas were best suited for a suborbital rocket flight launched from the Arctic. In a nod to the ship that carried Ernest Shackleton on his famous 1914 voyage to Antarctica, the team named their mission Endurance. The scientists set a course for Svalbard, a Norwegian archipelago just a few hundred miles from the North Pole and home to the northernmost rocket range in the world.
“Svalbard is the only rocket range in the world where you can fly through the polar wind and make the measurements we needed,” said Suzie Imber, a space physicist at the University of Leicester, UK, and co-author of the paper.
On May 11, 2022, Endurance launched and reached an altitude of 477.23 miles (768.03 kilometers), splashing down 19 minutes later in the Greenland Sea. Across the 322-mile altitude range where it collected data, Endurance measured a change in electric potential of only 0.55 volts.
“A half a volt is almost nothing — it’s only about as strong as a watch battery,” Collinson said. “But that’s just the right amount to explain the polar wind.”
The Endurance rocket ship launches from Ny-Ålesund, Svalbard. Credit: Andøya Space/Leif Jonny Eilertsen Hydrogen ions, the most abundant type of particle in the polar wind, experience an outward force from this field 10.6 times stronger than gravity. “That’s more than enough to counter gravity — in fact, it’s enough to launch them upwards into space at supersonic speeds,” said Alex Glocer, Endurance project scientist at NASA Goddard and co-author of the paper.
Heavier particles also get a boost. Oxygen ions at that same altitude, immersed in this half-a-volt field, weigh half as much. In general, the team found that the ambipolar field increases what’s known as the “scale height” of the ionosphere by 271%, meaning the ionosphere remains denser to greater heights than it would be without it.
“It’s like this conveyor belt, lifting the atmosphere up into space,” Collinson added.
Endurance’s discovery has opened many new paths for exploration. The ambipolar field, as a fundamental energy field of our planet alongside gravity and magnetism, may have continuously shaped the evolution of our atmosphere in ways we can now begin to explore. Because it’s created by the internal dynamics of an atmosphere, similar electric fields are expected to exist on other planets, including Venus and Mars.
“Any planet with an atmosphere should have an ambipolar field,” Collinson said. “Now that we’ve finally measured it, we can begin learning how it’s shaped our planet as well as others over time.”

Endurance was a NASA-funded mission conducted through the Sounding Rocket Program at NASA’s Wallops Flight Facility in Virginia. The Svalbard Rocket Range is owned and operated by Andøya Space. The European Incoherent Scatter Scientific Association (EISCAT) Svalbard radar, located in Longyearbyen, made ground-based measurements of the ionosphere critical to interpreting the rocket data. The United Kingdom Natural Environment Research Council (NERC) and the Research Council of Norway (RCN) funded the EISCAT radar for the Endurance mission. EISCAT is owned and operated by research institutes and research councils of Norway, Sweden, Finland, Japan, China, and the United Kingdom (the EISCAT Associates). The Endurance mission team encompasses affiliates of the Catholic University of America, Embry-Riddle Aeronautical University, the University of California, Berkeley, the University of Colorado at Boulder, the University of Leicester, U.K., the University of New Hampshire, and Penn State University.
