SpaceX’s Polaris Dawn mission poised to make history with first civilian spacewalk
(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 ultra-high 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 Sunday the Falcon 9 rocket that will carry the Polaris Dawn crew to orbit could launch as early as Tuesday at 3:38 a.m. ET from NASA’s Kennedy Space Center in Florida.
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,” he added.
(NEW YORK) — Former President Trump is seeking to push back sentencing in his criminal hush money case until after the 2024 presidential election, arguing that the current sentencing date of Sept. 18 advances what his attorneys call prosecutors’ “naked election-interference objectives.”
Judge Juan Merchan has already delayed sentencing once, at Trump’s request, following the U.S. Supreme Court’s recent decision on presidential immunity.
Trump was originally scheduled to be sentenced on July 11. Judge Merchan ruled last month that he would rule on Trump’s immunity claim on Sept. 16 and impose sentencing two days later.
“That timing illustrates just how unreasonable it is to have the potential for only a single day between a decision on first-impression Presidential immunity issues and an unprecedented and unwarranted sentencing,” defense lawyers wrote in a letter to judge on Thursday.
Trump’s lawyers questioned whether sentencing should take place after the start of early voting, arguing that the timing harms the integrity of the proceedings.
“Finally, setting aside naked election-interference objectives, there is no valid countervailing reason for the Court to keep the current sentencing date on the calendar. There is no basis for continuing to rush,” defense lawyers wrote.
Trump’s request for a delay comes one day after Merchan sharply criticized defense lawyers for raising “inaccurate and unsubstantiated claims” in their motion to have Merchan recused from the case based on an alleged conflict of interest involving his daughter and Vice President Kamala Harris. Merchan denied the motion.
Despite Merchan denying their recusal motion, Trump’s lawyers again raised their arguments about “conflicts and appearances of impropriety” in their letter urging a delayed sentencing.
Trump was convicted in May on all 34 counts of falsifying business records connected to a hush payment to adult film actress Stormy Daniels in order to boost his electoral prospects in the 2016 presidential election.
(ST. LOUIS) — A county prosecutor in St. Louis, Missouri, presented DNA evidence Wednesday alleging that a death row inmate convicted of first-degree murder is innocent in a case that has drawn opposition from the state attorney general.
Marcellus Williams, 55, who has maintained his innocence, is scheduled to be executed on Sept. 24 for the 1998 murder of Felicia Gayle, according to court documents. He was charged in 1999 and found guilty in 2001.
The St. Louis County Prosecuting Attorney’s Office, headed by Wesley Bell, told ABC News in a statement Wednesday that the lead prosecutor and investigator who initially tried the case two decades ago handled the knife used to kill Gayle without gloves and their DNA was found on the evidence.
“DNA from two members of the trial team were found on the murder weapon in testing we did for this hearing,” Bell’s office told ABC News in a statement Wednesday. “In open court today, a DNA expert testified that their improper handling of the weapon could have eliminated other DNA evidence. Williams’ DNA was never recovered from the knife.”
Bell’s office did not address whether they are asking the judge to invalidate the knife as evidence because of improper handling.
Williams was set to enter an Alford plea after a circuit court judge, and Bell agreed to it last week. An Alford plea would allow him to accept the consequences of a guilty plea but would not require him to admit specific wrongdoing to get his sentence reduced to life in prison without parole, according to the county prosecutor’s office.
Missouri Attorney General Andrew Bailey argued that the move to vacate Williams’ death sentence should not have been allowed, saying in a statement that the “defense created a false narrative of innocence in order to get a convicted murderer off of death row and fulfill their political ends.”
Wednesday’s hearing came after the Missouri State Supreme Court ruled last Thursday in favor of a request from Bailey for the circuit court to first hold an evidentiary proceeding before considering vacating the death sentence.
“It is in the interest of every Missourian that the rule of law is fought for and upheld – every time, without fail,” according to a statement from Bailey last Thursday. “I am glad the Missouri Supreme Court recognized that. We look forward to putting on evidence in a hearing like we were prepared to do yesterday [when the circuit judge agreed to vacate Williams’ death sentence].”
The State Attorney General’s Office did not respond to ABC News’ request for further comments after the evidentiary hearing.
The county prosecutor’s office submitted the 63-page motion on Jan. 26 to vacate Williams’ conviction.
“Despite the fact that no reliable evidence has ever connected Mr. Williams to the 1998 murder of Felicia Gayle,” The Innocence Project, who is representing Williams, told ABC News in a statement Wednesday. “Attorney General Andrew Bailey has vigorously fought to prevent the court from vacating Mr. Williams’ conviction and to execute him on September 24.”
In the summer of 2024, Bailey has litigated against three wrongful-conviction claims opposing local prosecutors and judges, according to The New York Times, including the Christopher Dunn case, in which the state attorney general did not accept the recanting of testimonies of two witnesses who previously tied Dunn to the murder of a teenager in 1990. Dunn was released from prison after Bailey appealed the ruling of a circuit court judge who vacated Dunn’s conviction.
Williams was convicted on June 15, 2001, of first-degree murder, first-degree burglary, armed criminal action and robbery connected to events at Gayle’s home in suburban St. Louis, according to court documents.
Gayle was found murdered with more than 43 stab wounds in her home on Aug. 11, 1998, according to the county prosecutor’s motion. The kitchen knife used in the killing was left lodged in Gayle’s body, according to court documents. Blood, hair, fingerprints and shoe prints believed to belong to the perpetrator were found around the home. Gayle’s purse and her husband’s laptop were declared missing after the attack, according to county prosecutor’s motion.
“None of this physical evidence tied Mr. Williams to Ms. Gayle’s murder,” according to the motion filed by Bell’s office. “Mr. Williams was excluded as the source of the footprints, Mr. Williams was excluded by microscopy as the source of the hairs found near Ms. Gayle’s body … and Mr. Williams was not found to be the source of the fingerprints.”
About a year after Gayle’s death, Henry Cole, a man who had been recently released from jail, told authorities that he had been Williams’ cellmate and heard him admit to the murder, according to court documents.
In November 1999, Laura Asaro, Williams’ girlfriend at the time, told police that Williams confessed to her that he killed Gayle, according to Bell’s motion. The prosecution’s case was largely dependent on these two witness accounts, the motion said.
In court documents, Bell’s office claimed there were significant issues with the credibility of Cole and Asaro’s accounts, which they said were inconsistent over time and contained testimony that didn’t line up with physical evidence. Bell’s office also alleged that both witnesses had incentives to testify, including a possible cash reward to find Gayle’s killer and, in Asaro’s case, an offer of help from police with her outstanding warrants.
Williams pawned the laptop stolen from Gayle’s home, but the motion alleges the buyer of the computer told investigators that Williams explained to him that Asaro had given him the laptop to sell for her. The jury who convicted Williams was not allowed to hear testimony that Williams said he received the laptop from Asaro because the testimony would have been hearsay. Williams was convicted in June 2001 and sentenced to death.
In 2017, when Williams was hours away from execution, then-Missouri Gov. Eric Greitens granted him a reprieve so a panel could evaluate his conviction.
Last year, Gov. Mike Parson disbanded the panel, according to court documents. A day after the governor dissolved the panel, Bailey asked the State Supreme Court to schedule an execution date. Parson said that he is open to discussing clemency for Williams, according to a statement on Monday obtained by ABC News.
“One of the defense’s own experts previously testified he could not rule out the possibility that Williams’ DNA was also on the knife. He could only testify to the fact that enough actors had handled the knife throughout the legal process that others’ DNA was present,” read a statement from Bailey last week.
The county prosecuting attorney’s office said the state’s claim that one of their expert witnesses could not rule out Williams’s DNA on the weapon was insignificant.
“The AG (attorney general) is arguing about a motion that was not taken up by the court today and has no bearing on the matter,” read the statement from Bell’s office.
The circuit court has until Sept. 13 to make a ruling on Williams’ case after the evidentiary hearing, according to court documents.
(HILO, Hawaii) — Hawaii’s Kilauea volcano, one of the most active in the world, is erupting again, prompting a volcano watch alert in surrounding areas, according to officials.
The eruption is occurring within a remote area of Hawaii Volcanoes National Park, according to the U.S. Geological Survey’s (USGS) Hawaiian Volcano Observatory.
Lava began flowing from a new fissure vent that opened from east to west within the volcano’s Nāpau Crater early Tuesday morning, the USGS said.
Several lava fountains about 32 feet high and pools of lava on the floor of the crater were observed by helicopters flying over the eruption Tuesday morning.
A separate fissure west of the Nāpau Crater began emitting lava on Monday, stopping after a few hours and then resuming activity later that evening, according to the USGS, which also noted that the eruption was preceded by a sequence of below-ground earthquakes.
About 17 earthquakes were detected beneath the Kilauea summit region between Monday and Tuesday. The earthquakes occurred at depths between .6 and 1.9 miles below the ground surface, the USGS said.
The USGS issued a volcano watch – known as a code orange – which means that an eruption is either likely or occurring but with no, or minor, ash.
There is no immediate threat to life or infrastructure, but residents nearby may experience volcanic gas emissions related to the eruption, the USGS said.
Yet hazards remain around the Kilauea caldera from the instability of the Halemaʻumaʻu crater wall, the USGS said. Ground cracking and rockfalls can be enhanced by earthquakes.
Volcanic smog, known as vog, presents airborne health hazards to people and livestock and has the potential to damage agricultural crops and other plants, according to the USGS.
The USGS further warned that additional ground cracking and outbreaks of lava around the active and inactive fissures in Kilauea are also possible.
Another potential hazard is Pele’s hair, a volcanic glass formation produced from cooled lava that’s stretched into thin strands. The USGS warns that winds could carry lighter particles from the strands downwind. Contact with the particles can cause skin and eye irritation, according to the USGS.
Eruptions at Kilauea have been destructive in the past. In 2018, more than 600 properties were destroyed by heavy lava flow that stretched from the Kilauea summit to the ocean.
Unusual eruptions that were described as being similar to a “stomp-rocket toy,” a children’s toy that involves launching a rocket into the air after stomping on the release mechanism, contributed to the severity of the lava flow and could potentially impact future eruptions, according to a paper published earlier this year in Nature Geosciences.
The area surrounding the rim of Kilauea’s Halemaʻumaʻu crater has been closed to the public since 2008 due to the hazards.
