The finest ever map of the cosmic microwave background - the faint evidence of the universe's early form - has yielded precise confirmation of the age of the cosmos and its rate of expansion. But for some scientists, the findings offer a frustrating lack of clues to major cosmological mysteries

The China Space Station Telescope, scheduled for a 2027 launch, will offer astronomers a fresh view on the cosmos. Though somewhat smaller than Hubble, it features a much wider field of view, giving a wide-field surveys that will map gravitational lensing, galaxy clusters, and cosmic voids. Scientists anticipate it will measure dark energy with 1% precision, differentiate between cold and dark matter models, and evaluate gravitational theories.

Media are invited to meet leaders in the space community during the 62nd annual Goddard Space Science Symposium, taking place from Wednesday, March 19, to Friday, March 21, at Martin’s Crosswinds in Greenbelt, Maryland. The symposium will also be streamed online.

Hosted by the American Astronautical Society (AAS) in conjunction with NASA’s Goddard Space Flight Center in Greenbelt, the symposium examines the current state and future of space science and space exploration at large by convening leading minds across NASA, other government agencies, policy, academia, and industry – collectively navigating a path forward by identifying the opportunities and challenges ahead.

This year’s theme, “Pathways and Partnerships for U.S. Leadership in Earth and Space Science,” highlights the evolving collaborative landscape between the public and private sectors, as well as how it is helping the United States remain and grow as a leading space power. 

“Earth and space science are complex by nature, with a growing list of public and private enterprises carving out their space,” said Christa Peters-Lidard, co-chair of the symposium planning committee and Goddard’s director of sciences and exploration. “It’s an exciting time as we work to determine the future trajectory of space exploration in this new era, and the Goddard Space Science Symposium is an instrumental tool for gathering the insights of leading experts across a broad spectrum.”

AAS President Ron Birk and Goddard Deputy Center Director Cynthia Simmons will deliver the symposium’s opening remarks on March 19, followed by panels on enabling science and exploration from the Moon to Mars and navigating space science and exploration policy. Greg Autry, associate provost for space commercialization and strategy at the University of Central Florida, will deliver the keynote address. The first day will conclude with an industry night reception.

The second day of the symposium on Thursday, March 20, will feature panels on enhancing U.S. economic leadership through science, the Habitable Worlds Observatory, and the confluence of public science and the private sector. Gillian Bussey, deputy chief science officer for the U.S. Space Force, will serve as the luncheon speaker.

Panels on the third and final day, March 21, will discuss integrating multi-sector data to advance Earth and space science, the Heliophysics Decadal Survey, and the space weather enterprise. Mark Clampin, acting deputy associate administrator for the NASA Science Mission Directorate, will provide the luncheon address.

Media interested in arranging interviews with NASA speakers should contact Jacob Richmond, Goddard acting news chief.

Skylab 3 astronauts witnessed many spectacular sights during their 858 orbital trips around the Earth in the summer of 1973. One involved watching powerful Hurricane Ellen take shape off the West African coast. “There’s a nice storm down there. She looks pretty big. She’s got a lot of clouds,” said astronaut Alan L. Bean upon viewing the storm from Skylab’s low-Earth orbit.

Knowing they were witnessing something of interest to meteorologists on Earth, Bean and his fellow Skylab crew members captured stereo photographs of the storm using cameras aboard the space station. Meteorologists later used these images, which provided three-dimensional data, to help them understand how the clouds in tropical systems formed and functioned.

This image of Hurricane Ellen was taken by Skylab astronauts in September 1973. Unscheduled weather observations that relied on the judgement and actions of Skylab astronauts captured valuable research data for scientists.NASA

Like the Skylab 3 crew’s photographs of Hurricane Ellen, the lightning observations of Skylab 4 astronaut Edward G. Gibson were also used by meteorologists to understand regional weather phenomena. While gazing down at a storm over South America’s Andes Mountains, Gibson noted that the thunderstorm he observed generated recognizable lightning patterns over a 500-square-mile region.

“A few things impressed me here: one is the fact that they could go off simultaneously or near simultaneously over a large distance—sympathetic lightning bolts, if you will, analogous to sympathetic flares on the sun. And that we do get periods of calm between periods of very high activity. Some sort of collective phenomenon appears to be at work,” Gibson recalled.

This photograph of Edward G. Gibson, Skylab 4 science pilot, was taken at Kennedy Space Center, Florida on November 8, 1973, before his November 16 launch to Skylab. Meteorologists were very interested in the regional lightning patterns he witnessed while aboard the space station.NASA

The photographs of Hurricane Ellen and Gibson’s notes about lightning patterns are just two of many valuable meteorological observations and recordings astronauts made during Skylab’s three crewed missions. All told, astronaut-conducted Earth studies provided important regional, also known as mesoscale, weather data that improved storm forecasting.

Along with providing valuable data to meteorologists, the notable findings of the Skylab astronauts supported the argument of the era’s scientists and mission planners who insisted that there was no adequate replacement for intelligent human observers in space.

Perhaps the authors of Living and Working in Space: A History of Skylab  put it best when they wrote: “Man’s ability to discriminate, to select the important features of a wide vista, and to respond effectively to unexpected events constituted his greatest contribution to orbital investigations.”
