(CAPE CANAVERAL, Fla.) — After two weeks of delays, the ambitious Polaris Dawn space mission, led by billionaire Jared Isaacman and in collaboration with SpaceX, launched early Tuesday morning.
The four-person civilian crew launched from the Kennedy Space Center in Florida on Tuesday at 5:23 a.m. ET in SpaceX’s Falcon 9 rocket, according to a social media post by the aerospace company.
Lift off came after one final two-hour delay due to “unfavorable weather at the launch site,” as reported SpaceX.
Isaacman, the CEO of the payment-processing company Shift4, is joined on the mission by former Air Force pilot Scott “Kidd” Poteet and two SpaceX engineers, Anna Menon and Sarah Gillis.
The highly anticipated program faced a series of delays since the originally planned Aug. 26 launch due to unfavorable weather conditions and a ground system issue at the launch site.
Prepping for another possible delay, SpaceX said ahead of the launch that the weather forecast for Tuesday remained uncertain.
“Weather is currently 40% favorable for liftoff, and conditions at the possible splashdown sites for Dragon’s return to Earth remain a watch item,” the company wrote on X Sunday.
Despite the forecast, Issacman remained hopeful about this week’s launch possibility, writing on X, “This is a big improvement over the last two weeks. We are getting closer to getting this mission to orbit.”
The mission was previously delayed due to a ground-side helium leak on the Quick Disconnect (QD) umbilical, SpaceX said on Aug. 26. Umbilical systems employ QD fluid connectors to transfer fluids into a vehicle, according to NASA.
If successful, the Polaris Dawn mission is poised to make history by launching four private citizens into ultrahigh orbit, ascending to 870 miles above Earth. This would be the highest altitude of any human spaceflight mission since the Apollo program, more than a half century ago.
The program is set to span five days under normal conditions and will see two of the crew members exit the spacecraft in the first commercial spacewalk, at an altitude of 435 miles above Earth.
Due to the absence of an airlock on the SpaceX Dragon capsule, all four crew members will be exposed to the vacuum of space during the ambitious spacewalk.
The spacewalk will also serve as a critical test for SpaceX’s new extravehicular activity (EVA) spacesuits, an evolution of the intravehicular activity (IVA) 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 the wearer to pressurize the suit, don a harness and execute operations as if they were weightless.
The Dragon spacecraft also 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 re-pressurization system has been installed, according to the program.
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 in Earth orbit.

(NEW YORK) — A new storm — which will strengthen into Hurricane Helene — is taking aim at Florida, where it’s forecast to make landfall along the Big Bend area as a hurricane on Thursday.
Here’s how the news is developing:
Tropical storm forecast to ‘rapidly’ intensify into major hurricane
Tropical Storm Helene was expected to “rapidly” strengthen and grow in size as it moved on Wednesday into the Gulf of Mexico, U.S. weather officials said.
The storm as of about 4 a.m. local time had maximum sustained winds of about 65 mph, the National Hurricane Center said. It was expected to intensify into a hurricane on Wednesday, before further strengthening into a “major” hurricane on Thursday, the center said.
Helene early Wednesday was traveling northwest at about 9 mph, the center said.
“On the forecast track, the center of Helene will pass near the northeastern coast of the Yucatan Peninsula this morning, move across the eastern Gulf of Mexico on later today and Thursday, and reach the Big Bend coast of Florida late Thursday,” the center said.
Biden approves Florida emergency declaration ahead of Helene’s landfall
As Florida residents prepare for Tropical Storm Helene to make landfall Thursday, the White House has approved the state’s emergency declaration.
President Biden’s approval allows for federal assistance to supplement state, tribal and local response efforts.
The Department of Homeland Security and the Federal Emergency Management Agency (FEMA) will coordinate all federal disaster relief efforts, according to the White House’s statement.
Biden’s approval Tuesday comes as officials in Sarasota County announced a Level A evacuation order for portions of two neighborhoods beginning Wednesday morning at 7:00 a.m. ET.
Officials encouraged residents in Curry Creek, Hatchett Creek, Venice and those in Forked Creek, Englewood to be aware of the conditions and stay alert for further updates.
Hurricane warnings issued for portions of Florida’s Panhandle, Big Bend and Gulf Coast
On the current track, Tropical Storm Helene is forecast to make landfall late Thursday night, between 8:00 and 10:00 p.m. ET, as a major Category 3 hurricane with winds up to 115 mph in the Florida Big Bend region.
Hurricane warnings have been issued for Florida’s Panhandle, Big Bend and Gulf Coast regions and hurricane watch warnings have extended into southern Georgia.
Officials have issued tropical storm warnings from Naples and Fort Myers to Orlando and tropical storm watch warnings are in place across Florida’s east coast up to Savannah, Georgia.
Helene’s latest forecast
Helene is expected to strengthen to a hurricane on Wednesday as it enters the Gulf of Mexico and strengthen further to a major Category 3 hurricane by Thursday morning.
A hurricane watch is in effect in Florida from Tallahassee to Tampa, where hurricane conditions will be possible late Wednesday night through late Thursday night.
Wednesday night into Thursday morning, Helene’s outer bands will start to lash Florida’s Gulf Coast. The worst of the conditions will be throughout the day on Thursday.
Helene is forecast to make landfall Thursday night along Florida’s Big Bend region as a Category 3 hurricane. Winds could be up to 115 mph during landfall.
Helene is expected to be a large hurricane, which means impacts will extend significantly beyond the center, impacting most of Florida and much of the Southeast.
After landfall, Helene is forecast to quickly move north into Georgia, bringing heavy rain and strong winds to the South.
A significant flash flood risk stretches from the Florida Panhandle to South Carolina — including Tallahassee to Atlanta — Thursday night into early Friday.

Universities, schools close ahead of Helene
Ahead of Helene, Florida A&M University in Tallahassee canceled class from Tuesday afternoon through Friday. The university will be closed Wednesday through Friday.
Florida A&M said this weekend’s home football game and parents’ weekend will be rescheduled.
Florida State University said its Tallahassee campus will be closed from Wednesday morning to Sunday night.
FSU Tallahassee students can stay on campus during the closure, but should plan for possible power outages and be prepared to possibly stay inside all day Thursday, the university warned.
Officials in Florida are also closing public schools in multiple counties, including Pasco, Pinellas, Hernando, Citrus and Sarasota.
Mandatory evacuations have been announced in parts of Charlotte and Franklin counties.
Helene strengthens to tropical storm: Latest forecast
Helene, currently located about 180 miles east southeast of Cozumel, Mexico, strengthened to a tropical storm on Tuesday morning.
The forecast shows Helene moving through the Yucatan Channel Wednesday morning, bringing near hurricane-force wind gusts to Cancun, Mexico.
By Thursday morning, coastal flooding will reach Florida, including Naples and Fort Myers.
On Thursday night, Helene will make landfall near Apalachicola, Florida.
Dangerous wind gusts up to 105 mph are expected and storm surge will be a major threat for the Tampa Bay area.
By Friday morning, the center of Helene will be near Atlanta, bringing strong winds to Georgia, Tennessee, South Carolina and North Carolina.
Downed trees and power lines will be a major danger across the Southeast.
The flash flood threat will continue into the weekend in the Tennessee, Ohio and Mississippi River Valleys.
State of emergency declared in 61 Florida counties
Helene is forecast to be a major hurricane by the time it makes landfall Thursday night, Florida Gov. Ron DeSantis warned Monday.
A state of emergency has been declared in 61 of Florida’s 67 counties, DeSantis said.
“The Big Bend and Panhandle should be especially prepared for a direct impact,” the governor said, and he urged residents to know their evacuation zone.
“You have time to be able to put this place into place,” DeSantis said, noting Helene’s impacts could begin Wednesday.
Latest forecast
Helene will strengthen to a hurricane Tuesday night, and rain is expected to begin in Florida Wednesday afternoon into Thursday morning.
On Thursday evening, Helene will make landfall along Florida’s Big Bend area, located between Tallahassee and Gainesville.
Storm surge could reach up to 15 feet in the Big Bend area.
Heavy rain and strong winds are also major threats.
A hurricane watch is in effect for Florida’s Gulf Coast and a tropical storm watch was issued from Orlando to the Florida Keys.
By Thursday night into Friday, the storm will quickly push into Georgia with very heavy rain, gusty winds and possible flash flooding.
This weekend, the storm will stall over the Mid-South, bringing heavy rain and possible flooding to the Tennessee, Ohio and Mississippi River Valleys.
A flood watch has been issued in Florida from Fort Myers to Tampa to Tallahassee, as well as in southern Georgia and Alabama.

(LONDON, Ky.) — Joseph A. Couch, the man authorities have named as a suspect in a Kentucky freeway shooting that left seven people injured, bought the weapon used in the incident legally on the morning of the shooting, authorities said Sunday night.
Laurel County Sheriff’s Commander Richard Dalrymple said at Sunday night’s news briefing that Couch purchased about a thousand rounds of ammunition, most of which has been recovered.
The suspect remains at large despite a massive search in the area of Saturday’s shooting north of London, Kentucky.
The shooting unfolded around 5:30 p.m. local time on Saturday evening, officials said. Arriving deputies initially found nine vehicles had been shot in both the north and southbound lanes of I-75, Laurel County Sheriff John Root said at a news conference late Saturday night. By Sunday night, that number had jumped to 12 vehicles, according to officials.
Root said deputies found five people with serious gunshot wounds, including one who was shot in the face. He said one vehicle contained two people who were shot.
Laurel County Sheriff’s Deputy Gilbert Acciardo said Sunday that none of the victims suffered life-threatening injuries and were all in stable condition.
“A couple of our deputies, because of the severity of the injuries, loaded the people up, the injured persons, and transported them to London Hospital,” Root said.
Two additional people were injured in a car crash that occurred during the shooting, authorities said.
Root said I-75 was immediately shut down in both directions, saying that at the time, deputies didn’t know where the bullets came from.
“We couldn’t risk somebody else being shot,” Root said.
Authorities previously said they found an AR-15 rifle in the woods near the crime scene on Interstate 75, about eight miles north of London, Kentucky. Couch’s vehicle was also found abandoned in the same area Saturday night, officials said Sunday afternoon.
Couch was first named as a person of interest in the incident but upgraded to a suspect on Sunday. Root said the decision to name Couch a suspect was based on evidence collected in the investigation. Asked to elaborate, Root said that the recovery of the weapon and Couch’s vehicle, as well as “some information” he could not share, prompted investigators to elevate Couch to a suspect in the shooting.
The sheriff’s office earlier released a photo of Couch, who allegedly fled the freeway shooting and was believed to still be in the area, Root said.
Root said Couch has an address in Woodbine, Kentucky, and the sheriff’s office described him as about 5-foot-10-inches tall and 154 pounds.
Dalrymple said Sunday night that the suspect allegedly fired from a ledge about 30 feet down from a cliff by Exit 49. To find the location, Dalrymple said he had to hold onto a tree and look down to see the site to find the location.
Earlier, Acciardo described the shooting as “sniper-like” and said it was not the result of road rage. He said investigators do not believe the shooter knew any of the victims or had contact with them before the shooting.
Up to 60 members of law enforcement searched the area of the shooting until 3 a.m. Sunday before halting the search due to safety concerns, saying it was pitch black on the highway and describing the terrain where the search was being conducted as very rugged.
More than 150 individuals were involved in the search for Couch on Sunday, with efforts set to resume on Monday morning, according to Root.
The FBI, the U.S. Marshal’s Service and the federal Bureau of Alcohol, Tobacco, Firearms and Explosives are assisting local authorities in the investigation, officials said.
A motive for the shooting remained under investigation.
Kentucky Gov. Andy Beshear said in a statement on X on Saturday that he was monitoring the situation.
In an interview Sunday on ABC’s Good Morning America, Christina Dinoto said she was driving with a friend southbound on I-75, heading to Tennessee, when the shooting erupted.
“All of a sudden, we just heard this loud, deafening sound,” Dinoto said. “And my ear, my right ear, started ringing, and we didn’t know what the sound was, but we both looked at each other and said, was that a gunshot?”
Dinoto said that when she pulled off the interstate in Knoxville, she discovered damage to her vehicle that she suspects was caused by a bullet that may have ricocheted off another car.
The Kentucky shooting came less than a week after six people were injured in six shootings that occurred on Sept. 2 on Interstate 5 in Washington state between 8:26 p.m. and 11:01 p.m. local time, officials previously said. A suspect whose vehicle was sought in connection with several of the shootings was arrested in the Tacoma area on Sept. 3, police said.
