n case you haven’t noticed, you may be sleeping better at night.
The cosmic dream state you’re in could include mind-bending thoughts about an impending asteroid impact on Earth. That’s messy business. Moreover, that space rock intrusion here on Earth can, and already has, meant doom and destruction.

But where are we today in dealing with any intruder from afar in our collective air space?
Lindley Johnson has been a pioneer in blueprinting warning and response scenarios to any potential impact of Earth by an asteroid or comet. He led the establishment of the Planetary Defense Coordination Office at NASA in January 2016. Prior to NASA, he served 23 years of Air Force active duty working on a host of national security space systems.

Written testimony of Jared Isaacman at today’s U.S. Senate Committee on Commerce, Science, and Transportation confirmation hearing to become the next NASA administrator:
If confirmed, and with the support and guidance of President Trump and members of Congress, we will reinvigorate a mission-first culture at NASA with the following objectives:
First—American astronauts will lead the way in the ultimate ‘high ground’ of space. As the President stated we will prioritize sending American astronauts to Mars. Along the way, we will inevitably have the capabilities to return to the Moon and determine the scientific, economic, and national security benefits of maintaining a presence on the lunar surface. We will focus our technology development efforts on the world’s greatest engineering challenges, such as the practical application of nuclear propulsion, so that we can truly unlock humankind’s ability to explore among the stars.
Second—We will ignite a thriving space economy in low Earth orbit. By working alongside international partners and industry, we can unlock the true economic potential of space and deliver meaningful benefits to the American people–potentially charting a course for NASA to become a financially self-sustaining agency.
Third—NASA will be a force multiplier for science. We will leverage NASA’s scientific talent and capabilities to enable academic institutions and industry to increase the rate of world-changing discoveries. We will launch more telescopes, more probes, more rovers and endeavor to better understand our planet and the universe beyond.

In Earth orbit since October 2024, China’s Shenzhou-19 crew continues to perform in-orbit mechanical, robotic, medical tests.
China’s Shenzhou-19 space travelers — Cai Xuzhe, Song Lingdong and Wang Haoze – have been at work on the country’s Tiangong space station for more than 150 days.
A newly issued video from China Central Television (CCTV) shows the trio carrying out experiments on equipment withdrawal, sample collection, and component reassembly and reuse.
Pipe inspection robots
CCTV notes the crew has tested pipe inspection robots to help realize self-examinations of the orbital outpost in the future.
Also completed are medical experiments such as blood collection, centrifugal treatment, and cryopreservation, and coordinated an eye tracker and a laptop to record data on their eye movements in the station’s microgravity environment.

Emergency response training
The station’s regenerative life support system is being maintained, with the Sheznhou-19 crew carrying out physical examinations on themselves, including blood routine and blood biochemistry tests, body weight measurement, and intraocular pressure checks. The station’s exercise equipment continues to be utilized to gather data on what effects the micro-gravity environment has on human bodies.
Lastly, reports CCTV, the astronauts performed emergency response training by donning and doffing pressure suits in case there’s need to respond to emergency situations.

Reflect back decades ago to the heady Space Race rivalry between the former Soviet Union and America. For the entire world, it was the Sputnik moment, the orbiting of the first artificial satellite of Earth by the Soviets.
Sputnik 1’s liftoff on October 4, 1957 sparked worries, made all the more vexing by the embarrassing and humiliating failure later that year of America’s first satellite launch. The Navy’s Vanguard rocket went “kaputnik” as the booster toppled over and exploded.
An emotional rescue for America came via the first U.S. artificial satellite. Explorer 1 was boosted into space by the Army on January 31, 1958.
Nevertheless, despite setbacks, Vanguard 1 did reach orbit on March 17, 1958 as the second U.S. satellite.

Still up there
And guess what? While Explorer 1 reentered Earth’s atmosphere in 1970, the Naval Research Laboratory’s (NRL) Vanguard 1 microsatellite is still up there. It just celebrated 67 years of circuiting our planet.
Now there’s interest in recovering the tiny spacecraft and haul it back home from whence it came!

China’s Moon exploration plans are being detailed, a step-by-step program leading to the development of the country’s International Lunar Research Station.
Headed for the Moon around 2026 is the robotic Chang’e-7 mission, built to explore the lunar south pole, specifically to gather data regarding the evidence of water. If confirmed, such deposits could enable future lunar exploration goals by providing drinking water, oxygen and rocket fuel production capabilities.
The subsequent mission in 2028, Chang’e-8, is to test technologies for building habitats using lunar soil.
China is moving forward on lunar soil brick technology to support the International Lunar Research Station, or ILRS, on the Moon. Chang’e-8 is also to spearhead the building of communication systems and energy systems.

Brick by brick
In a China Central Television (CCTV) interview, Wu Weiren, chief designer of the Chinese Lunar Exploration Program said: “Now we have developed the world’s first device that produces bricks made of lunar soil. This system harnesses sunlight, collects solar energy, and transmits it to the Moon using fiber optics.”
Wu added that, by concentrating the sunlight, temperatures between 1400 to 1500 degrees Celsius, can be attained, which is sufficient to melt lunar soil.
“Our device then utilizes 3D printing technology to shape the molten material into bricks of various specifications. This approach allows us to utilize resources found on the Moon, free from transporting water and other materials from the Earth,” Wu told CCTV.
China lunar research station planning underway.

Once verified, the lunar soil brick technology will provide key support for the ILRS, Wu said.
Higher stage
“I hope more countries, more international scientific research institutions and more foreign scientists will participate in the construction of our entire project,” said Wu.
“I think in the next 10 to 20 years,” Wu continued, “we should mainly take the international lunar research station as a starting point or as a guide to push the lunar exploration program to a higher stage.”

That first-ever pole to pole orbital voyage of the Fram2 crew continues to go well.
Entrepreneur Chun Wang, mission commander, is posting video and images and commentary regarding the flight. He is joined by three others, Australian adventurer Eric Philips, filmmaker Jannicke Mikkelsen, and German robotics researcher Rabea Rogge.

In an X posting Wang said the ride to orbit was much smoother than he had anticipated. “Apart from the final minute before SECO, I barely felt any G-forces—it honestly felt like just another flight.”
Wang said he had imagined it would feel like being in an elevator that suddenly drops, but that sensation never came. “If I hadn’t set free Tyler, the polar bear zero-gravity indicator, I might not have realized we were already weightless. I think being tightly strapped into our seat buckets made the transition less noticeable.”

Space motion sickness
The first few hours in microgravity weren’t exactly comfortable for the Fram2 crew.
“Space motion sickness hit all of us—we felt nauseous and ended up vomiting a couple of times. It felt different from motion sickness in a car or at sea. You could still read on your iPad without making it worse. But even a small sip of water could upset your stomach and trigger vomiting,” Wang explains.

Movie night
“Rabea spent some time on the ham radio, making contact with Berlin. No one asked opening the cupola on the first day—we were all focused on managing the motion sickness. We had a movie night watching our own launch and went to sleep a bit earlier than scheduled. We all slept really well.”

Wang added that by the second morning, he felt completely refreshed.
“The trace of motion sickness is all gone. We had breakfast, took a few X-ray images, and opened the cupola three minutes after midnight UTC—right above the South Pole.”

The upcoming crewed flight of the Fram2 mission into polar orbit from Florida is a risky undertaking in many ways.
Riding atop a SpaceX Falcon 9 booster, the Fram2 crew — commander Chun Wang, vehicle commander Jannicke Mikkelsen, vehicle pilot Rabea Rogge, and mission specialist and medical officer Eric Philips — face multiple challenges.
Fram2 is the first human spaceflight over the Earth’s polar regions.

Unique risks
“It’s an exciting mission with lots of important firsts…but of course also with some unique risks,” said Jan Osburg, a RAND senior engineer in the engineering and applied sciences department and a specialist in space safety.
Osburg told Inside Outer Space that risks include dealing with the radiation environment and the unusual orbit.

“If anything goes wrong that would preclude the capsule from reentering, they can’t get to an in-orbit safe haven like the International Space Station, both due to their different orbit and due to the airlock for this flight having been replaced with the Dragon Cupola, like during the Inspiration4 mission a few years ago,” Osburg advised.
Robust design
Not having an airlock, Osburg said, also means the crew would have to transfer to a rescue vehicle via space walks, if that rescue vehicle – another Crew Dragon, for example — could be launched in time. “Not sure if they will carry the new SpaceX EVA suits with them just for such a dire contingency, though,” he said.

On the other hand, the Crew Dragon seems to be a very robust design, Osburg added, “and the crew, while new to spaceflight, are experienced explorers and should be used to extreme environments and high-risk decision-making.”
Dogleg maneuver
Regarding the radiation environment given the polar flight, Osburg said he assumes the Dragon spacecraft, including its avionics, has been extensively tested for its ability to withstand the higher radiation environment. Additionally, the medical implications should be manageable due to the short exposure time of a few days, he said.
At the latitude flown by the Fram2 crew, they are susceptible to high-energy charged particles penetrating the Earth’s magnetosphere.
On departure from Launch Complex 39A at NASA’s Kennedy Space Center in Florida, the trajectory to attain a polar orbit likely requires a “dogleg” maneuver during ascent, said Osburg.
SpaceX has done this maneuver a couple of times with un-crewed missions already, Osburg added, to avoid overflying Florida’s Gold Coast. “This costs fuel, but the Falcon 9 can do it,” and even land the booster’s first stage on a droneship afterwards.”
To avoid overflying Florida’s Gold Coast. Image of how that trajectory could look like, based on a previous Falcon 9 flight. This August 30, 2020 mission marked SpaceX’s first launch to a polar orbit from the East Coast, and the first polar launch from Florida in decades.

High inclination
According to a Fram2 press statement, with the exception of the Apollo lunar missions, the Earth’s North and South Poles have not been fully visible to other astronauts in orbit, including those onboard the International Space Station. To date, the highest inclination achieved by human spaceflight has been the Soviet Vostok 6 mission, at 65-degrees, in 1963.
Vostok 6 was piloted by the first woman into Earth orbit, cosmonaut Valentina Tereshkova.
The Fram2 mission is named after the original Fram ship that first reached the Earth’s polar regions in the 1800s.

Research activities
Throughout the nearly four-day mission, among an array of over 20 research activities, the Fram2 crew will capture data about the polar regions.
In collaboration with the University Center of Svalbard, Fram2 will support the SolarMaX Mission to film aurora-like phenomena to create an open-source database of aurora photographs for researchers and citizen scientists.
The crew has also teamed up with Amateur Radio on the International Space Station (ARISS International), to host Fram2Ham, a polar history focused competition for the ham radio community.
One biomedical experiment has been developed by the Falak for Space Science and Research, a nonprofit organization in Saudi Arabia. The study will examine how microgravity affects the eye’s microbiome, specifically investigating bacterial behavior, antibiotic resistance, and biofilm formation.
SpaceX is targeting Monday, March 31, at 9:46 p.m. Eastern Florida Time for Falcon 9’s launch of the Fram2 crew to a polar orbit from NASA’s Kennedy Space Center.
