A SpaceX Crew Dragon(a.k.a. Resilience) lifted off atop a SpaceX Falcon 9 rocket on Tuesday(Sept. 10) at 0923 UTC from historic Launch Complex-39A at NASA's Kennedy Space Center (KSC). Aboard the spacecraft are Polaris Dawn mission astronauts headed to about 1,400 kilometers away from Earth, higher than any human has flown since the final Apollo mission in 1972.

Approximately 9.5 minutes after liftoff, the Falcon 9 first stage returned to Earth as expected, landing on SpaceX autonomous droneship Just Read the Instructions(JRTI), stationed off Florida's eastern coast in the Atlantic Ocean. Crew Dragon meanwhile, separated from the Falcon 9's upper stage a little over 12 minutes after liftoff.

"We wouldn't be on this journey without all 14,000 of you back home and everyone else cheering us on," billionaire entrepreneur Jared Isaacman, who commands and funds Polaris Dawn, told SpaceX mission control shortly after Resilience deployed into orbit. "We appreciate it. We're gonna get to work now." Joining him aboard are the first two SpaceX employees to launch to orbit, mission specialists Sarah Gillis and Anna Menon, as well as retired U.S. Air Force Lt. Col. Scott "Kidd" Poteet, who serves as mission pilot.

Resilience settled into an initial elliptical orbit with a maximum altitude (apogee) of about 1,200 km, with the minimum altitude (perigee) holding at about 190 km. Then after a few orbits, the capsule will raise its apogee to about 1,400 km.

Isaacman, who has been to space once before, and his crewmates will spend the next five days in space, completing a wide variety of tests and experiments in the novel space environment that the mission is exploring.

After Polaris Dawn's second day in space, Crew Dragon will lower its apogee to about 700 km, at which altitude the crewmembers will conduct the most critical part of their mission: history's first commercial spacewalk. This is also the altitude where the Dragon will remain until its deorbit burn and return to Earth.

The EVA (extravehicular activity) will take place on the third day of the mission when a SpaceX's new EVA spacesuit, which is visually similar to the company's familiar black-and-white IVA (intravehicular activity) suit, will be tested. Crew Dragon doesn't have an airlock, so the capsule's entire interior will be exposed to the vacuum of space during the EVA. All four crewmembers will therefore suit up during the spacewalk, though only Isaacman and Gillis will venture outside the spacecraft.

Isaacman and Gillis will take turns exiting Crew Dragon to test the functionality and maneuverability of their suits. In total, the Polaris Dawn EVA will last about two hours from the start of Crew Dragon's depressurization until the hatch is closed and the cabin repressurized.

The mission's fourth day includes a Starlink demonstration; the Polaris Dawn crew has teased an exciting surprise message they intend to transmit down to Earth via SpaceX's megaconstellation of internet satellites.

Polaris Dawn crew will also conduct about 40 science experiments during the mission. "Aboard commercial mission Polaris Dawn are @NASA studies that test telemedicine tech, gather data on space-related motion sickness, & better assess crews’ injury risk upon landing," NASA wrote on X.

The crew will spend day five preparing for the return journey home. Resilience is expected to splash down six days after liftoff, off the coast of Florida where a recovery ship will retrieve the spacecraft and crew.

Polaris Dawn was originally scheduled to launch on Aug. 26, but SpaceX stood down from that attempt to perform more preflight checks. Another try the following day was called off after the mission team detected a helium leak in the equipment supporting the Falcon 9. The liftoff was then delayed multiple times by bad weather, before Tuesday's successful launch

SDA T1TL-C: SpaceX Launches 21 US Military Communication Satellites

A SpaceX Falcon 9 rocket launched at 2306 UTC on Oct. 15, from Space Launch Complex 4E at Vandenberg Vandenberg Space Force Base in California, deploying 21 satellites for the U.S. Space Force’s Space Development Agency (SDA) Tranche 1 Transport Layer (T1TL) constellation. This T1TL-C mission marked the second deployment of the T1TL network, with the satellites built by Lockheed Martin and designed to provide global, low-latency military data connectivity through optical inter-satellite links.

The Falcon 9 first stage booster B1093, which completed its seventh flight, successfully landed on the drone ship "Of Course I Still Love You" positioned in the Pacific Ocean, about 8 minutes after liftoff. B1093 also launched SpaceX's first T1TL mission on Sept. 10, as well as five flights carrying the company's Starlink broadband satellites.

The rocket's second stage meanwhile, flying on a southerly trajectory, placed the 21 satellites into a polar low Earth orbit less than an hour after launch.

The 21 satellites are part of the SDA’s Proliferated Warfighter Space Architecture (PWSA), designed to enable beyond-line-of-sight, secure, real-time communication for military forces worldwide by relaying data through a mesh network. The Transport Layer is intended to expand the range of the U.S. military’s Link 16 tactical data network to virtually any location on Earth.

The satellites were manufactured by Lockheed Martin, which secured a $700 million contract in 2022 to produce 42 satellites for Tranche 1. The spacecraft buses were supplied by Terran Orbital, a Lockheed Martin subsidiary  This mission was the second of six planned T1TL launches for Tranche 1, which will eventually include 126 Transport Layer satellites and 28 Tracking Layer satellites.

The first T1TL mission launched on September 10, 2025, carrying 21 satellites built by York Space Systems. The SDA, established in 2019, aims to reduce reliance on large geostationary satellites by deploying smaller, commercially built spacecraft in low Earth orbit using rapid acquisition methods and mostly Elon Musk SpaceX's efficient rocket and satellite capabilities.

Trump Posthumously Awards Presidential Medal Of Freedom To Charlie Kirk

President Donald Trump posthumously awarded the Presidential Medal of Freedom to conservative activist Charlie Kirk at a White House ceremony on Tuesday, on what would have been Kirk’s 32nd birthday. The event, held in the Rose Garden, featured emotional remarks from Trump and Kirk’s widow, Erika Kirk, who accepted the honor on her husband’s behalf.

Charlie Kirk, co-founder of Turning Point USA, was assassinated on September 10, 2025, during a debate at Utah Valley University as part of his "America Comeback Tour." His organization played a significant role in mobilizing young voters for Trump in the 2024 election, particularly in key battleground states like Arizona. Vice President JD Vance, a close friend, accompanied Kirk’s casket on Air Force Two from Utah to Arizona.

Trump described Kirk as a "martyr for truth and freedom" and a "visionary" who galvanized young voters, while Erika Kirk praised her husband’s faith, fearlessness, and servant’s heart, noting he prayed for his enemies.

Trump called Kirk a "fearless warrior for liberty" and a "champion in every way," and stated he "raced back halfway around the globe" from the Middle East to attend, having just brokered a ceasefire between Hamas and Israel. He credited Kirk with helping him win the 2024 election and mobilizing young voters, joking that without him, Kamala Harris might have been president.

The president also used the occasion to condemn "far-left radicals," claiming they have a "devil’s ideology" and calling for "absolutely no tolerance" for radical left violence, extremism, and terror. He referenced the sounds of sirens from the Rose Garden as "real-deal sirens" and "beautiful," linking them to law enforcement and national security.

Erika Kirk accepted the medal and shared a heartfelt message from her 3-year-old daughter, who wished her father a happy birthday with a stuffed animal, cupcake, and surprise. She also spoke of her husband’s deep faith and his potential to run for president, stating he would have done so only if he believed it was necessary for the country, not out of ambition.

The widow said of Kirk, "Surprisingly enough, he did pray for his enemies, which is very hard, but he did," drawing laughter from the crowd. She also highlighted her son’s early potty training as a "gift" to her and Charlie.

The ceremony was attended by numerous high-profile figures, including Vice President Vance, second lady Usha Vance, Attorney General Pam Bondi, Defense Secretary Pete Hegseth, FBI Director Kash Patel, and prominent conservative media personalities like Tucker Carlson, Sean Hannity, and Laura Ingraham. The Trump administration also revoked visas of six foreign nationals for making negative comments about Kirk.

Flight 11: SpaceX Tests New Starship Landing Burns, Ship Banking Maneuvers, Subsonic Guidance Algorithms

SpaceX launched Starship Flight 11 from Pad 1 at Starbase on October 13, at about 2323 UTC, marking the final flight test for the Version 2 iteration of the megarocket system and the last use of the current Pad 1 configuration.

The mission concluded with the Super Heavy booster performing a controlled splashdown in the Gulf of Mexico and the Ship 38 upper stage successfully splashing down in the Indian Ocean about one hour and six minutes after liftoff, following a suborbital trajectory that included a payload deployment demonstration, an in-space engine relight test, and a dynamic banking maneuver during reentry.

Flight 11 also marked this Super Heavy(B15)'s second flight, following a successful catch during Flight 8 in March 2025, and it was the third booster caught by the launch tower at Pad A. For this mission, SpaceX reused 24 of its 33 Raptor 2 engines, with the booster performing a landing burn starting with 13 engines and transitioning to five for added redundancy before splashing down in the Gulf of Mexico.

Following launch, the flight followed a suborbital profile similar to previous tests, with the Super Heavy booster executing a new landing burn engine configuration planned for future Block 3 boosters. The booster performed a boostback burn, followed by a landing burn, and splashed down in the Gulf of Mexico approximately 6.5 minutes after liftoff.

Accorging to SpaceX, "This was the final flight of the second-generation Starship and first generation Super Heavy booster, as well as the final launch from the current configuration of Pad 1. Every major objective of the flight test was achieved, providing valuable data as we prepare the next generation of Starship and Super Heavy.

"The flight test began with Super Heavy igniting all 33 Raptor engines and ascending over the Gulf. The successful first-stage ascent was followed by a hot-staging maneuver, with Starship’s upper stage igniting its six Raptor engines to continue its flight to space.

"Following stage separation, the Super Heavy booster completed its boostback burn to put it on a course to a pre-planned splashdown zone off the coast of Texas using 12 of the 13 planned engines. Under the same angle of attack tested on the previous flight, the booster descended until successfully igniting all 13 planned engines (including one that did not relight during the boostback burn) for the high-thrust portion of the landing burn. The booster successfully executed a unique landing burn planned for use on the next generation booster. Super Heavy hovered above the water before shutting down its engines and splashing down."

Ship 38 mission objectives include, deploying eight Starlink satellites simulators (totaling ~16,000 kg) to simulate payload release; in-space Raptor relight for deorbit maneuvers; and heat shield stress tests by intentionally removing tiles without ablative backups to expose bare steel and assess plasma exposure.

The mission deployed eight Starlink mass simulators into a suborbital trajectory, simulating the deployment of next-generation (V3) Starlink satellites. Another key objective was the demonstration of a single Raptor engine relight in space, occurring approximately 38 minutes into the flight, which validates critical capabilities for deep-space missions. Heat shield modifications were tested by removing tiles lacking an ablative backup section in vulnerable areas to stress-test the thermal protection system during reentry.

Ship 38, the final Block 2 Starship vehicle, completed its mission with a controlled reentry into Earth's atmosphere, passing through transonic and subsonic regimes before initiating its landing burn. It executed a dynamic banking maneuver during descent, testing subsonic guidance algorithms needed for future return-to-launch-site landings. The ship successfully splashed down in the Indian Ocean northwest of Western Australia at approximately 1:06:25 after liftoff.

According to SpaceX, "After completing a full-duration ascent burn, Starship achieved its planned velocity and trajectory. During flight, Starship successfully deployed eight Starlink simulators and executed the third in-space relight of a Raptor engine, demonstrating a critical capability for future deorbit burns.

"Starship re-entered the Earth’s atmosphere and was able to gather extensive data on the performance of its heatshield as it was intentionally stressed to test the limits of the vehicle’s capabilities. In the final minutes of flight, Starship performed a dynamic banking maneuver to mimic the trajectory that future missions returning to Starbase will fly. Starship then guided itself using its four flaps to the pre-planned splashdown zone in the Indian Ocean, successfully executing a landing flip, landing burn, and soft splashdown."

This flight was the eleventh test of the Starship system and the final flight for the Block 2 Starship and Super Heavy vehicles. Booster 15, which previously flew on Flight 8, was reused with 24 flight-proven Raptor engines and was intended to test configurations for the upcoming Block 3 booster.

According to SpaceX, "Focus now turns to the next generation of Starship and Super Heavy, with multiple vehicles currently in active build and preparing for tests. This next iteration will be used for the first Starship orbital flights, operational payload missions, propellant transfer, and more as we iterate to a fully and rapidly reusable vehicle with service to Earth orbit, the Moon, Mars, and beyond"
