Should the Senate confirm him, Isaacman will be the first billionaire – but not the first astronaut – to head NASA. Perhaps even more significant, he will be the first NASA administrator with significant ties to the commercial space industry. As a space policy expert, I know that NASA leadership matters. The head of the agency can significantly shape the missions it pursues, the science it undertakes and, ultimately, the outcome of America’s space exploration.Jared Isaacman speaks at a news conference in 2024, before his Polaris Dawn mission.AP Photo/John Raoux, File
An unconventional background
At 16 years old, Isaacman dropped out of high school to start a payment processing company in his basement. The endeavor succeeded and eventually became known as Shift4. Though he found early success in business, Isaacman also had a love for aviation. In 2009, he set a record for flying around the Earth in a light jet, beating the previous record by more than 20 hours. While remaining CEO of Shift4, Isaacman founded another company, Draken International. The company eventually assembled the world’s largest fleet of privately owned fighter jets. It now helps to train U.S. Air Force pilots. In 2019, Isaacman sold his stake in Draken International. In 2020, he took Shift4 public, making him a billionaire. Isaacman continued to branch out into aerospace, working with SpaceX beginning in 2021. He purchased a crewed flight on the Falcon 9 rocket, a mission that eventually was called Inspiration4. The mission, which he led, represented the first private astronaut flight for SpaceX. It sent four civilians with no previous formal space experience into orbit. Following the success of Inspiration4, Isaacman worked with SpaceX to develop the Polaris Program, a series of three missions to help build SpaceX’s human spaceflight capabilities. In fall 2024, the first of these missions, Polaris Dawn, launched. Polaris Dawn added more accomplishments to Isaacman’s resume. Isaacman, along with his crewmate Sarah Gillis, completed the first private spacewalk.

The next adventure: NASA
In December 2024, the incoming Trump administration announced its intention to nominate Isaacman for the post of NASA administrator. As NASA administrator, Isaacman would oversee all NASA activities at a critical moment in its history. The Artemis program, which has been in progress since 2017, has several missions planned for the next few years. This includes 2026’s Artemis II mission, which will send four astronauts to orbit the Moon. Then, in 2027, Artemis III will aim to land on it.If the mission proceeds as planned, the Artemis II crew will fly in an Orion crew capsule, pictured behind them, around the Moon in 2026.Kim Shiflett/NASA via AP, File But, if Isaacman is confirmed, his tenure would come at a time when there are significant questions about the Artemis program, as well as the extent to which NASA should use commercial space companies like SpaceX. The agency is also potentially facing funding cuts. Some in the space industry have proposed scrapping the Artemis program altogether in favor of preparing to go to Mars. Among this group is the founder of SpaceX, Elon Musk. Others have suggested canceling NASA’s Space Launch System, the massive rocket that is being used for Artemis. Instead, they argue that NASA could use commercial systems, like SpaceX’s Starship or Blue Origin’s New Glenn. Isaacman has also dealt with accusations that he is too close to the commercial space industry, and SpaceX in particular, to lead NASA. This has become a larger concern given Musk’s involvement in the Trump administration and its cost-cutting efforts. Some critics are worried that Musk would have an even greater say in NASA if Isaacman is confirmed. Since his nomination, Isaacman has stopped working with SpaceX on the Polaris Program. He has also made several supportive comments toward other commercial companies. But the success of any of NASA’s plans depends on having the money and resources necessary to carry them out. While NASA has been spared major cuts up to this point, it, like many other government agencies, is planning for budget cuts and mass firings. These potential cuts are similar to what other agencies such as the Department of Health and Human Services have recently made. During his confirmation hearing, Isaacman committed to keeping the Artemis program, as well as the Space Launch System, in the short term. He also insisted that NASA could both return to the Moon and prepare for Mars at the same time. Although Isaacman stated that he believed NASA had the resources to do both at the same time, the agency is still in a time of budget uncertainty, so that may not be possible. About his relationship with Musk, Isaacman stated that he had not talked to Musk since his nomination in November, and his relationship with SpaceX would not influence his decisions. Additionally, he committed to carrying out space science missions, specifically to “launch more telescopes, more probes, more rovers.” But since NASA is preparing for significant cuts to its science budget, there is some speculation that the agency may need to end some science programs, like the Hubble space telescope, altogether.
Isaacman’s future
Isaacman has received support from the larger space community. Nearly 30 astronauts signed a letter in support of his nomination. Former NASA administrators, as well as major industry groups, have signaled their desire for Isaacman’s confirmation. He also received the support of Senator Ted Cruz, the committee chair. Barring any major development, Isaacman will likely be confirmed as NASA administrator by the Senate in the coming weeks. The Committee on Commerce, Science, and Transportation could approve his nomination once it returns from a two-week break at the end of April. A full vote from the Senate would follow. If the Senate does confirm him, Isaacman will have several major issues to confront at NASA, all in a very uncertain political environment.Wendy Whitman Cobb, Professor of Strategy and Security Studies, Air University This article is republished from The Conversation under a Creative Commons license.

DoorDash Driver Arrested After Claiming Sexual Assault: What Really Happened?
A DoorDash driver who claimed she was sexually assaulted during a delivery is now facing felony charges after police say her viral video showed an unconscious, partially nude customer without consent. Here’s what investigators found and why the case is sparking national debate.
DoorDash delivery driver involved in a viral video controversy after claiming sexual assault; police say no assault occurred, and the driver now faces felony charges.
DoorDash Driver Arrested After Claiming Sexual Assault: What Really Happened?
A Viral Accusation Turns Into a Criminal Case
A routine food drop-off turned into a national controversy this month after a DoorDash delivery driver claimed she was sexually assaulted during a delivery — only to later be arrested herself following a police investigation. The incident, which quickly spread across TikTok and other platforms, has generated fierce debate over privacy, personal safety, and the power of viral video culture.
The driver, identified as Livie Rose Henderson, posted a video on social media in mid-October claiming that when she arrived at a customer’s home in Oswego, New York, she found the front door open and discovered a man “half-naked and unconscious” on his couch. She publicly described the moment as a sexual assault, saying she felt endangered and traumatized.
Her posts went viral almost immediately, drawing attention from millions of viewers and sparking outrage over the safety risks faced by gig workers — particularly women — who make deliveries to unfamiliar homes.
But the narrative took a dramatic turn.
Police: No Sexual Assault Occurred
According to the Oswego Police Department, an investigation found no evidence that Henderson was sexually assaulted. Instead, authorities say that she:
Entered the home without consent
Recorded the unconscious customer, who was partially nude
Posted the footage online, identifying him
Made claims police say were “false and misleading”
Investigators concluded the man was intoxicated and unconscious, not acting with intent or awareness. As a result, Henderson was arrested and charged with:
Second-degree unlawful surveillance (felony)
First-degree dissemination of unlawful surveillance images (felony)
Police emphasized that recording a person who is nude or partially nude inside their home — regardless of context — constitutes a violation of New York’s surveillance and privacy laws if done without permission.
DoorDash Drops the Driver
Henderson also claimed that DoorDash deactivated her account, something she described as retaliation for “exposing her assaulter.” But following her arrest, DoorDash stated that recording customers inside their homes violates company policy and local laws.
DoorDash said it cooperated with investigators but declined to comment further on personnel matters.
A Complicated Public Reaction
Social media reaction has been sharply divided:
Advertisement
Sympathy for the driver
Many viewers initially supported Henderson, arguing that gig workers often deal with unsafe conditions and should not be forced to decide between finishing a delivery or backing away from a potentially threatening situation.
Backlash over privacy violations
Others argue that Henderson crossed legal and ethical boundaries by:
Entering a private residence
Recording a vulnerable, unconscious person
Posting it publicly
Accusing the individual of a crime without evidence
These actions, critics say, show the dangerous consequences of rushing to social media before police or professional investigators evaluate the facts.
The Larger Issue: Safety vs. Responsibility
This case highlights a broader tension in the era of app-based work and viral content:
Gig workers do indeed face unpredictable and sometimes unsafe situations.
Customers have a right to privacy in their homes.
Social media, meanwhile, rewards the fastest and most dramatic version of a story — even before the truth is known.
As the criminal process continues, Henderson’s case may set a new precedent for how privacy laws interact with the realities of delivery work and the instant visibility of online platforms.
Focuses on the legal perspective, privacy violations, and the potential consequences of posting sensitive content online.

How China cleaned up its air pollution – and what that meant for the climate
How China cleaned up its air pollution: Beijing’s air quality went from hazardous to good while Delhi and Lahore still struggle. Discover how China dramatically reduced pollution since 2013—and why cleaner air may have unintended consequences for global warming and climate change.
Delhi: 442. Lahore: 334. Beijing: 16. These are the levels of PM 2.5, one of the principle measures for air pollution, on November 19. As Pakistanis and Indians struggle with hazardous air quality, in Beijing – a city once notorious for its smog – the air quality is currently rated as good. Ahead of the 2008 Beijing Olympics, the Chinese government was so concerned about pollution that it introduced temporary restrictions on cars, shut down factories and stopped work on some construction sites. The measures worked and one study later found that levels of air pollution were down 30% during the period when the temporary Olympic restrictions were in place. It would take a few more years before the Chinese government implemented a clean air action plan in 2013. Since then, China has achieved a dramatic improvement in its air quality. In this episode of The Conversation Weekly podcast, we speak to Laura Wilcox, a professor at the National Centre for Atmospheric Science at the University of Reading in the UK, to understand how China managed to clean up its air pollution. But Wilcox’s recent research uncovered some unintended consequences from this cleaner air for the global climate: the pollution was actually helping to cool the atmosphere and by taking it away, it may have accelerated global warming. Wilcox explains:
What we’re seeing is a removing of cooling that’s revealing warming that’s already there. So the air pollution isn’t the cause of the warming. It’s just letting us see stuff that we’ve already done.

The Hong Kong high-rise fire shows how difficult it is to evacuate in an emergency
Hong Kong High-Rise Fire: The deadly Hong Kong fire exposes critical challenges in evacuating tall buildings. Learn why stair descent is slower than expected, how human behavior causes delays, and what modern safety features can save lives.
Evacuations of high-rises don’t happen every day, but occur often enough. And when they do, the consequences are almost always severe. The stakes are highest in the buildings that are full at predictable times: residential towers at night, office towers in the day. We’ve seen this in the biggest modern examples, from the World Trade Center in the United States to Grenfell Tower in the United Kingdom. The patterns repeat: once a fire takes hold, getting thousands of people safely down dozens of storeys becomes a race against time. But what actually makes evacuating a high-rise building so challenging? It isn’t just a matter of “getting people out”. It’s a collision between the physical limits of the building and the realities of human behaviour under stress.
It’s a long way down to safety
The biggest barrier is simply vertical distance. Stairwells are the only reliable escape route in most buildings. Stair descent in real evacuations is far slower than most people expect. Under controlled or drill conditions people move down at around 0.4–0.7 metres per second. But in an actual emergency, especially in high-rise fires, this can drop sharply. During 9/11, documented speeds at which survivors went down stairs were often slower than 0.3 m/s. These slow-downs accumulate dramatically over long vertical distances. Fatigue is a major factor. Prolonged walking significantly reduces the speed of descent. Surveys conducted after incidents confirm that a large majority of high-rise evacuees stop at least once. During the 2010 fire of a high-rise in Shanghai, nearly half of older survivors reported slowing down significantly. Long stairwells, landings, and the geometry of high-rise stairs all contribute to congestion, especially when flows from multiple floors merge into a single shaft. Slower movers include older adults, people with physical or mobility issues and groups evacuating together. These reduce the overall pace of descent compared with the speeds typically assumed for able-bodied individuals. This can create bottlenecks. Slow movers are especially relevant in residential buildings, where diverse occupants mean movement speeds vary widely. Visibility matters too. Experimental studies show that reduced lighting significantly slows down people going down stairs. This suggests that when smoke reduces visibility in real events, movement can slow even further as people hesitate, misjudge steps, or adjust their speed.
Human behaviour can lead to delays
Human behaviour is one of the biggest sources of delay in high-rise evacuations. People rarely act immediately when an alarm sounds. They pause, look for confirmation, check conditions, gather belongings, or coordinate with family members. These early minutes are consistently some of the costliest when evacuating from tall buildings. Studies of the World Trade Center evacuations show the more cues people saw – smoke, shaking, noise – the more they sought extra information before moving. That search for meaning adds delay. People talk to colleagues, look outside windows, phone family, or wait for an announcement. Ambiguous cues slow them even further. In residential towers, families, neighbours and friend-groups naturally try to evacuate together. Groups tend to form wider steps, or group together in shapes that reduce overall flow. But our research shows when a group moves in a “snake” formation – one behind the other – they travel faster, occupy less space, and allow others to pass more easily. These patterns matter in high-rise housing, where varied household types and mixed abilities make moving in groups the norm.
Why stairs aren’t enough
As high-rises grow taller and populations age, the old assumption that “everyone can take the stairs” simply no longer holds. A full building evacuation can take too long, and for many residents (older adults, people with mobility limitations, families evacuating together) long stair descents are sometimes impossible. This is why many countries have turned to refuge floors: fire- and smoke-protected levels built into towers as safe staging points. These can reduce bottlenecks and prevent long queues. They give people somewhere safe to rest, transfer across to a clearer stair, or wait for firefighters. Essentially, they make vertical movement more manageable in buildings where continuous descent isn’t realistic. Alongside them are evacuation elevators. These are lifts engineered to operate during a fire with pressurised shafts, protected lobbies and backup power. The most efficient evacuations use a mix of stairs and elevators, with ratios adjusted to the building height, density and demographics. The lesson is clear: high-rise evacuation cannot rely on one tool. Stairs, refuge floors and protected elevators should all be made part of ensuring vertical living is safer.Milad Haghani, Associate Professor and Principal Fellow in Urban Risk and Resilience, The University of Melbourne; Erica Kuligowski, Principal Research Fellow, School of Engineering, RMIT University, and Ruggiero Lovreglio, Professor in Digital Construction and Fire Engineering, Te Kunenga ki Pūrehuroa – Massey University This article is republished from The Conversation under a Creative Commons license.
