(MERRITT ISLAND, Fla.) — Embarking on a new chapter of private space exploration, the Polaris Dawn mission is poised to make history this week by launching four private citizens into ultrahigh orbit and attempting the first civilian spacewalk.
Led by billionaire Jared Isaacman and in collaboration with SpaceX, the crew aims to reach as far as 870 miles above Earth, the highest altitude of any human spaceflight mission in more than a half-century since the Apollo program.
SpaceX announced Monday that the Falcon 9 rocket that will carry the Polaris Dawn crew to orbit could launch as early as Wednesday at 3:38 a.m. ET from NASA’s Kennedy Space Center in Florida. The launch was delayed 24 hours from the planned pre-dawn Tuesday blast-off.
The delay is due to a ground-side helium leak on the Quick Disconnect umbilical, SpaceX said.
Umbilical systems employ fluid connectors known as quick disconnects to transfer fluids into a vehicle, according to NASA.
“Falcon and Dragon remain healthy and the crew continues to be ready for their multi-day mission to low-Earth orbit,” the company added.
There are two additional launch opportunities within the four-hour window on Wednesday at 5:23 a.m. and 7:09 a.m. ET. If needed, backup opportunities are available on Thursday, Aug. 29 at the same times, according to SpaceX.
Isaacman, the CEO of the payment-processing company Shift4, will be joined by former Air Force pilot Scott “Kidd” Poteet and two SpaceX engineers, Anna Menon and Sarah Gillis.
During the historic mission, which is set to span five days under normal conditions, two of the crew members will exit the spacecraft in the first commercial spacewalk at an altitude of 435 miles above Earth.
During a press briefing last week, Isaacman shared details on the ambitious mission, which will see all four crew members exposed to the vacuum of space due to the absence of an airlock on the SpaceX Dragon capsule.
The spacewalk will also serve as a critical test for SpaceX’s new Extravehicular Activity spacesuits, an evolution of the intravehicular activity suit.
This new design includes a heads-up display, helmet camera and enhanced joint mobility. It also features thermal insulation, solar protection and a suspension system that allows you to pressurize the suit, put on a harness and actually go through operations as if you are weightless.
The Dragon spacecraft has undergone significant modifications, including upgrades to the life support systems to supply more oxygen during spacewalks, according to the Polaris Program. Environmental sensing has been improved, and a new nitrogen repressurization system has been installed.
The Polaris Dawn mission will be Isaacman’s second journey to space.
In 2021, he funded his first mission to orbit Earth. The project was billed as a childhood cancer fundraiser, garnering $250 million for St. Jude Children’s Research Hospital, and marked the first all-civilian mission to orbit.
Looking to the future, Isaacman believes the SpaceX vehicles could unlock a new frontier in commercial space travel.
“It could very well be the 737 for human space flight someday,” he said of the company’s Starship vehicle. “But it’ll certainly be the vehicle that will return humans to the moon and then on to Mars and beyond.”
(NEW YORK) — The U.S. wildfire season is continuing on a relentless pace across the West as a new blaze erupted in Southern California, destroying multiple homes and leaving residents little time to evacuate, authorities said.
The Edgehill Fire erupted Monday afternoon in the Little Mountain community and quickly tore up a hillside, destroying at least a half-dozen homes, according to fire officials.
“We were so grateful for this house and I can’t believe it’s gone,” Erika Hernandez, whose home was burned to the ground, told ABC Los Angeles station KABC-TV.
The Edgehill Fire is the latest in a California wildfire season that has already burned nearly 800,000 acres and destroyed more than 1,000 structures, according to the California Department of Forestry and Fire Protection (Cal Fire).
Wildfires have burned more than 4.6 million acres across the United States, including 200,000 acres in just the first five days of August, according to the National Interagency Fire Center.
On Tuesday, nearly 30,000 firefighters were battling 89 large active wildfires across California, Oregon and other Western states.
Capt. Andrew Bonhus said the Edgehill Fire was an example of how fast fires in the West, fueled by an abundance of dried-out vegetation and extremely high temperatures, have spread this year.
“This fire specifically moved extremely rapidly compared to others … on this hilltop,” Bonhus told ABC News.
The Edgehill Fire, east of Los Angeles, was initially reported around 2:30 p.m. local time as a five-acre blaze. But within three hours, the fire ballooned to more than 50 acres, catching multiple homes on fire as it crested a hillside, leaving residents with just minutes to evacuate, officials said.
At least 200 firefighters from several agencies, including firefighting helicopter crews, raced to put out the flames, officials said.
“We didn’t even start at the base of the fire. We go straight for the houses and start evacuations and start getting lines out to help protect structures and, most importantly, life,” Bonhus said.
Around 5:45 p.m. local time, the San Bernardino County Fire Department announced that the fire’s forward progress was stopped and that 25% of the blaze was contained.
The cause of the fire is under investigation.
Fortunately, according to Bonhus, many residents in the area had taken steps to create “defensible space” around their homes by clearing dry bush, trees and other potential hazards that can fuel a wildfire.
“Because of the defensible space around the houses, some were savable, some were not,” Bonhus said. “It kind of pushes home how critical having defensible space around your homes is.”
The Park Fire
In Northern California, firefighters continued to battle to Park Fire, which was started by an alleged arsonist on July 24 and as of Tuesday had burned 414,042 acres of wildland in Butte, Plumas, Shasta and Tehama counties, according to Cal Fire. The fire has destroyed 640 structures, including homes and businesses.
The blaze, the largest in the United States this year and the fourth biggest in California history, was 34% contained on Tuesday.
The Nixon Fire
Another large Southern California blaze, dubbed the Nixon Fire, which started on July 29, was 96% contained on Tuesday after burning 5,222 acres near the Riverside County town of Aguanga, according to Cal Fire.
At least 23 structures, including homes and businesses, were destroyed by the Nixon Fire and another three structures were damaged, according to Cal Fire.
Investigators determined the Nixon Fire was sparked by a privately owned electrical panel that caught fire. The agency did not say who owns the electrical panel or specify whether negligence is suspected.
Durkee Fire in Eastern Oregon
More than 1 million acres of wildland have burned in Oregon this year, according to the National Interagency Fire Center. Oregon has seen some of the biggest fires in the nation, including the Durkee Fire in the eastern part of the state that had burned 294,265 acres as of Tuesday, according to the fire center.
The blaze, which started July 17, was 86% contained on Tuesday and state fire officials said they expected to have it completely extinguished by the end of this week.
Alexander Mountain Fire
Colorado firefighters are also getting the upper hand on the Alexander Mountain Fire, which was first reported on July 29, according to the U.S. Forest Service. The fire burning west of the city of Loveland in a remote mountainous area near Roosevelt National Park has charred 9,668 acres, the U.S. Forest Service said Tuesday morning.
The fire was 74% contained, according to the Forest Service. More than 900 homes remained under mandatory evacuation on Tuesday. The fire has destroyed 45 structures, including 25 homes, officials said.
The fire remains under investigation, but fire officials said it appeared to be human-caused.
(NEW YORK) — A 37-year-old backpacker has died after suffering “sudden onset medical complications” while hiking at a national park in Michigan, authorities said.
The currently unnamed 37-year-old female hiker from Battle Creek, Michigan, was with a hiking partner late Monday afternoon near Lake LeSage at Isle Royale National Park in Michigan when authorities say she began to experience “sudden onset medical complications,” according to a statement from the National Park Service detailing the incident.
“As her condition deteriorated, she was eventually unable to walk, lost consciousness, and stopped breathing,” park officials said. “CPR was provided but attempts to resuscitate her were unsuccessful.”
Other backpackers in the area were able contact Michigan State Police who subsequently relayed the message to a National Park Service dispatch center, NPS said.
“Park ranger/EMTs located and stayed with the party Monday evening. Early Tuesday morning a crew of Isle Royale staff responded to transport the party from a remote location,” authorities said.
“The Isle Royale community extends their sincere condolences to the family and friends of the deceased,” NPS continued.
An investigation into the woman’s death is currently ongoing.
(NEW YORK) — Hurricane Debby is roaring across Florida as a Category 1 hurricane after making landfall Monday morning.
A hurricane warning was issued for Florida’s Big Bend area, from near Cedar Key to Apalachicola.
Here’s how the news is developing:
13-year-old boy killed by fallen tree among two confirmed fatalities
A 13-year-old boy was killed when a tree fell on a mobile home Monday morning in Levy County, Florida, which encompasses Cedar Key, according to the Levy County Sheriff’s Office.
“Our thoughts and prayers are with this family as they deal with this tragedy,” the sheriff’s office said in a statement. “We encourage everyone to use extreme caution as they begin to assess and clean up the damage. Downed powerlines and falling trees are among the many hazards.”
In Hillsborough County, Florida, which encompasses Tampa, a driver of a semi was killed when the truck went into a canal off Interstate 275 Monday morning, according to the Hillsborough County Sheriff’s Office.
Deputies recovered the semi and found the driver dead inside the cab, authorities said.
“It’s just heartbreaking,” Tampa Mayor Jane Castor told ABC News Live. “We really ask everyone, one, to be aware of the weather situations in your area, and then heed the warnings. Especially the high wind and the water.”
More than 1,600 flights canceled

Debby approaches landfall with 80 mph winds
Hurricane Debby is “very near” landfall along Florida’s Gulf Coast, the National Hurricane Center said at 5 a.m. ET.
“Expected to bring life-threatening storm surge in portions of Florida and major flooding in the southeastern United States,” the center said in an update.
The Category 1 storm had maximum sustained winds of an about 80 mph as it approached Big Bend, a northern area near the Panhandle, the center said.
Debby strengthens, with maximum sustained winds up to 80 mph
Hurricane Debby continued to strengthen, with maximum sustained winds rising to 80 mph, making it a Category 1 hurricane, according to the National Hurricane Center.
More than 10 inches of rain fell on the west coast of Florida, around the Tampa Bay area, where water rescues have been on going near Clearwater. Significant flooding also has been reported in Fort Myers area.
Storm surge has been rising quickly now along the Big Bend area in Florida, from Cedar Key to Keaton Beach, where up to 10 feet of Gulf water could inundate the coastline. The storm is forecast to make landfall in that area on Monday morning.
Coast Guard rescues two adrift in sailboat off Florida coast
Two people were rescued Sunday from a boat that was adrift in about 20-foot seas off the coast of Boca Grande, Florida, the U.S. Coast Guard said.
The boaters were airlifted from their 34-foot sailboat after the vessel lost its sail about 73 miles off shore, the guard said.
The sailboat had been on course for Tarpon Springs from Key West, officials said. A friend of the boaters contacted the Coast Guard at about 5 p.m. Saturday, telling officials they had missed their check-in.
“We received an updated satellite position from the boaters’ friend, which led to them being successfully located,” Lt. Cmdr. Christopher Hooper, a search and rescue mission coordinator, said in a statement.
The boaters were rescued by a crew on an Air Station Clearwater MH-60 Jayhawk helicopter at about 11 a.m. on Sunday, the Coast Guard said. They had been adrift in seas that were between 15 and 20 feet, with wind speeds at about 50 knots. Visibility was low.
The names of the people on the boat were not released.
Debby strengthens into a hurricane
The National Hurricane Center has upgraded Tropical Storm Debby to a Category 1 hurricane with winds of 75 mph.
The forecast is still on track for more strengthening overnight as Debby feeds off the warm water in the eastern Gulf of Mexico. Water temperatures running 3 to 5 degrees above average are providing plenty of fuel for this storm to intensify before landfall, which will happen around 7 a.m. ET along the Big Bend region of Florida.
Tropical Storm Debby nearing hurricane strength at 70 mph
While still a tropical storm, Debby is nearing hurricane strength, producing maximum sustained wind speeds up to 70 mph.
Debby will continue to intensify rapidly overnight as it travels northward over the Gulf’s warm waters. It is forecast to become a hurricane tonight. It is expected to strengthen to at least a strong Category 1 hurricane before making landfall along Florida’s Big Bend region Monday morning (around 7 a.m. ET), producing sustained wind speeds near 85 mph and wind gusts reaching over 100 mph possible.
Located about 90 miles southwest of Cedar Key, Florida, the storm continues to impact the Florida Gulf Coast with heavy rainfall, storm surge, powerful winds and even spin-up tornadoes.
A reported wind gust of 56 mph was reported in St. Petersburg, with two tornadoes reported in central Florida.
A 60-mph wind gust was also reported near Sarasota, Florida.
Numerous reports of flooding from heavy rainfall and surges have also been submitted up Florida’s Gulf Coast.
The Tornado Watch covering much of northern and central Florida and southern Georgia has been extended until 6 a.m. ET on Monday.
Once Debby moves over land, it will weaken. However, the lack of a steering current will cause the storm to slow down considerably. While its exact track remains questionable, model guidance suggests the storm will drift over the Atlantic or Southeast coastline late Monday night into Tuesday before meandering back over Georgia and the Carolinas. Interaction with the Atlantic could reenergize Debby, but that will greatly depend on the storm’s path.
Even though Debby’s track and timing remain uncertain later this week, there is high confidence that it will bring historic rainfall and significant flooding across portions of the Southeast.
Rainfall ranging between 6 to 12 inches is possible from Florida’s Big Bend region through southeastern Georgia and into the Carolinas. Parts of coastal Georgia and South Carolina will be in the bullseye for the heaviest rainfall. There, widespread totals between 10 to 20 inches are possible, with some places even seeing up to 30 inches locally. Because of this, significant urban and river flooding is anticipated.
Rainfall aside, hurricane and tropical storm force winds will continue to whip across Florida and will likely intensify Sunday night into Monday as the storm moves closer to the coast — with areas just south and east of the storm’s eyewall seeing the strongest gusts early Monday morning.
Storm surge will also worsen along Florida’s northern and central Gulf coast tonight into Monday morning, with the highest surge expected between Suwannee River and Ochlockonee River (6 to 10 feet).
All tropical alerts remain unchanged from the last update.
Tropical Storm Debby on track to become a hurricane overnight
As of 5 p.m. ET on Sunday, Tropical Storm Debby still has winds of 65 mph and is forecast to undergo rapid intensification into a hurricane overnight, according to the National Hurricane Center.
Debby is expected to make landfall as a hurricane in Florida’s Big Bend region on Monday morning around 7 a.m.
Rain is expected to be the most impactful element from this storm, affecting a wide area over an extended period of time.
“Across portions of southeast Georgia and South Carolina, 10 to 20 inches of rainfall, with local amounts to 30 inches, are expected through Friday morning,” the National Hurricane Center said. “This potentially historic rainfall will likely result in areas of catastrophic flooding.”
Evacuations ordered in Alachua County, Florida, as Debby set to make landfall
An evacuation order was issued Sunday for residents of Alachua County, Florida, residing in mobile homes, manufactured homes and recreational vehicles ahead of the arrival of Debby, which is forecast to be a hurricane when it makes landfall on Monday.
People living in areas close to rivers and lakes, and low-lying areas that tend to flood in Alachua County are also encouraged to evacuate, according to a statement issued by county officials.
Gainesville is the largest city in Alachua County.
“We encourage residents affected to find alternative housing with friends, family or short-term rentals,” according to the county’s statement.
Alachua County is opening three shelters for residents in need.
Tornado watch issued as Debby runs parallel to Florida’s Gulf Coast
A tornado watch was issued Sunday afternoon by the National Weather Service as Tropical Storm Debbie moved northward in the Gulf of Mexico parallel to Florida’s Gulf Coast.
At 2 p.m. Sunday, the National Hurricane Center said Debby was still a tropical storm with winds of 65 mph and forecasted to bring severe weather, including heavy rain, to coastal communities Sunday afternoon.
A tornado watch is in effect for much of Florida through Sunday evening.
Debby is expected to become a hurricane Sunday evening and will likely make landfall sometime between 7 a.m. and 8 a.m. Monday in the Big Bend area of Florida’s Panhandle.
Once Debby makes landfall, the storm is expected to slow down and essentially stall over the Southeast, dropping potentially historic amounts of rainfall as it moves into Georgia and South Carolina.
A hurricane warning is in effect for the west coast of Florida from the Ochlockonee River southwest of Tallahassee to the Suwannee River northwest of Gainesville.
More than 1,600 flights canceled due to Debby and Northeast thunderstorms
Tropical Storm Debby and thunderstorms in the Northeast were causing airlines to cancel or delay flights on Sunday.
American Airlines said it canceled 601 flights, or about 16% of its flights, on Sunday, the most of any airline.
Debby, now a tropical storm in the Gulf of Mexico, is expected to make landfall around the Big Bend area of the Florida Panhandle on Monday morning as a Category 1 hurricane.
Also causing delays and cancellations were severe thunderstorms moving up the East Coast. Parts of the mid-Atlantic states are under a severe thunderstorm watch until 9 p.m. ET Sunday, including the cities of Washington, D.C., Baltimore, Philadelphia, and New York City.
The most flights canceled on Sunday were at Charlotte Douglas International Airport, where 214 flights were canceled and another 172 were delayed, according to FlightAware.
In New York City, LaGuardia and John F. Kennedy international airports reported a combined 363 flights canceled and 258 delayed on Sunday.
Miami International Airport reported 209 canceled flights and 151 delayed fights. Airports in Orlando, Tampa, Philadelphia, Newark, Washington, D.C., and Dallas-Fort Worth all reported more than 100 flight cancellations on Sunday.
Ten million people under tropical storm alert on Florida’s Gulf Coast
About 10 million people along Florida’s west coast and up through Georgia and South and North Carolina were under a tropical storm alert Sunday as Debby took aim at the area and is forecast to make landfall in the Panhandle region on Monday.
Debby, now a tropical storm in the Gulf of Mexico about 190 miles southwest of Tampa, is expected to make landfall sometime between 7 and 8 a.m. in Big Bend on the Florida Panhandle as a Category 1 hurricane, state emergency officials said.
Debby is expected to create a storm surge of 4 to 7 feet in Cedar Key and Crystal River on the Florida west coast and a 2- to 5-foot storm surge farther south in Tampa and Sarasota.
The storm is forecast to move into the cities of Tallahassee and Jacksonville, bringing up to 20 inches of rain to some parts, before causing potential flooding in Georgia and the Carolinas on Tuesday, Wednesday and Thursday.
National Guard put on alert for search and rescue: DeSantis
Members of the Florida National Guard have been advised to be prepared to conduct search-and-rescue missions once Tropical Storm Debby makes landfall on Monday, according to Florida Gov. Ron DeSantis.
Widespread flooding is expected for the Florida Panhandle region, particularly in the Big Bend area where Debby is expected to make landfall Monday morning as a category 1 hurricane, DeSantis said during a news conference Sunday morning.
DeSantis said the Florida National Guard and the state’s Emergency Response Team are prepared to conduct search-and-rescue and provide humanitarian assistance.
“The Florida National Guard is standing by with 3,000 service members ready to assist the state Emergency Response Team, which includes search-and-rescue, route clearance, commodity distribution and protection of critical infrastructure,” DeSantis said.
The governor said at least 12 swift boat crews and flat-bottom jon boat crews are also standing by to help with rescues.
He said that more than 30,000 bottles of water, more than 160,000 meals and nearly 14,000 tarps have been pre-staged in parts of Florida that are expected to be hit hard by the storm.
DeSantis said Florida utility companies have notified up to 17,000 linemen to be ready to spring into action once it is safe to repair any damage.
Flooding forecast as Debby expected to bring up to 20 inches of rain
Florida residents in the Big Bend region of the Panhandle were warned Sunday that Debby is going to bring “catastrophic rain to the area” that will cause flooding and power outages.
Kevin Guthrie, director of the Florida Division of Emergency Management, said during a news conference on Sunday that once the Debby makes landfall as a possible Category 1 hurricane on Monday morning, winds will subside quickly, but the slow-moving storm will produce an abundance of rain.
“We’re going to be in a catastrophic rain situation where we have situations in Florida that will receive 15, maybe as high as 20 inches of rain,” Guthrie said.
Florida Gov. Ron DeSantis told residents who are in the path of the storm to expect widespread power outages.
“It’s possible that you could have serious intensification between now and landfall. It could get up to 85, 90 and 95 mph sustained winds. That is absolutely possible, particularly in parts of the state like here in Tallahassee. There’s going to be a lot of trees that are going to fall down and you’re going to have debris. You are going to have power interruptions,” the governor said.
Gov. DeSantis advises residents to make final preparations for Debby
Florida Gov. Ron DeSantis advised residents of the state’s Panhandle region on Sunday that they should be finalizing preparations for when Tropical Storm Debby makes its anticipated landfall Monday morning as a Category 1 hurricane.
“Now this is a storm that is potentially dangerous. Residents should be finalizing all of their preparations now,” DeSantis said during a news conference at the state’s Emergency Operation Center in Tallahassee.
DeSantis said Tropical Storm Debby was in the Gulf of Mexico about 190 miles southwest of Tampa as of Sunday morning with sustained winds of about 50 mph.
“But those are expected to increase,” DeSantis said. “Tropical Storm Debby is likely to become a Category 1 hurricane before making landfall in the Big Bend region of Florida.”
He said the storm was on a similar track taken by Hurricane Idalia in 2023. Idalia made landfall in Big Bend on Aug. 30, 2023, as a Category 3 hurricane and caused a devastating storm surge of 7 to 12 feet across the coastal Big Bend region in Levy, Dixie and Taylor counties.
“This storm is a similar track,” DeSantis said. “It may be a tick to the west of that. It very well may have greater impacts here in the Tallahassee region than Hurricane Idalia did. Once it crosses landfall and enters the Florida Panhandle/Big Bend Region, wherever it does, it’s going to move very slowly across northern Florida and southeast Georgia.”
