NASA’s Mars Rover blasts off on ULA rocket for mission to the red planet
The summer of worldwide Mars missions saved the best for last with the successful launch of NASA’s most advanced rover ever. Following on the heels of the successful launches of China’s Tianwen-1 Mars spacecraft and the United Arab Emirates Hope Mars mission, NASA joined the 309 million miles (497 million kilometers) interplanetary journey to the Red Planet with the successful launch of the Mars 2020 Perseverance mission. Safely secured to the top of a mighty United Lunch Alliance Atlas V 541 rocket and Centaur upper stage, NASA’s car-sized Perseverance rover – and accompanying Ingenuity helicopter – left Earth on Thursday morning (July 30) in spectacular fashion. Getting off this planet, however, is only the beginning.
Why go to Mars again?
The Mars 2020 Perseverance mission is perhaps NASA’s most ambitious Mars mission. Formally announced in 2012, the then-unnamed Mars 2020 rover would be tasked with studying the Red Plane in a way that had never been attempted before. It would be collecting samples for eventual return to Earth in search of finding evidence of ancient microbial life.
NASA’s 2012 Curiosity mission uncovered the fact that Mars was rich in material that could have potentially supported microbial life once upon a time. Now, eight years later, the Perseverance mission will hunt for and collect the evidence to back up that claim.
A rover tasked with such an important astrobiological mission required NASA to develop the most technologically advanced range of scientific instruments that had ever been sent to Mars. As described by NASA, Perseverance is outfitted with seven different “state-of-the-art tools for acquiring information about Martian geology, atmosphere, environmental conditions, and potential signs of life (biosignatures).” Perseverance will be the first rover to collect and cache samples of the Martian surface to later be collected and eventually returned to Earth by future joint NASA and European Space Agency missions.

It is also the first rover to travel to Mars with a vast array of high-definition cameras with advanced imaging capability. Perseverance will also carry high-definition microphones with it, allowing, for the first time, the sounds of Mars to be captured. This will include the ability to hear entry, descent, and landing from the point of view of the rover, as well as the sound of what it’s like to drive over the Martian terrain.
Perseverance also carries with it two demonstration missions. Onboard is MOXIE, or the Mars Oxygen ISRU Experiment, designed to test technology that can convert carbon dioxide in the Martian atmosphere into oxygen – an important precursor experiment to one day sending humans to Mars. Also aboard is Ingenuity, the first-ever rotorcraft – or helicopter – designed to fly on another planet. Ingenuity will test the effectiveness of rotorcrafts on other planets with different atmospheric and gravitational makeup than Earth to perhaps one day serve as planetary observational crafts or delivery systems.
Leaving Earth was the easy part, sort of
A major challenge that faced the Mars 2020 mission was completing final integrations during the global Coronavirus pandemic, which required most NASA and JPL personnel to work from home. NASA LSP senior launch director, Omar Baez, stated that “I never would have thought that a launch director would be working from home and I’ve done that for the last five months.” He went on further to state that “It’s humbling to see how our whole team from the range, to our partners at JPL, to our partners at ULA, to our folks at headquarters – how we all had to adjust to work in this environment, to work electronically.” Although challenging, the Mars 2020 mission persevered to overcome the obstacles and meet the targeted launch date.
The Mars 2020 mission initially targeted a July 18th liftoff at the very opening of the available one-month interplanetary launch window. The mission did suffer a few minor setbacks during the integration phase when ULA had to take a few days to address an issue with a crane at the Vertical Integration Facility pushing the launch date to July 22nd. Then, as explained in a statement provided by NASA the launch date suffered another delay, this time eight days to July 30, “due to launch vehicle processing delays in preparation for spacecraft mate operations.”
The ULA Atlas V in its 541 configuration consisting of a common core booster and four solid rocket motors fully stacked with the precious payload stood 197 feet (60 meters) tall. The Atlas V 541 provided 2 million lbs of thrust rocketing the spacecraft east away from Florida over the Atlantic Ocean. After approximately ninety seconds of flight, the solid rocket motors burned out, separating away from the booster followed quickly by stage separation. The Centaur upper-stage was the workhorse of the mission left to deliver the Mars 2020 payload to its Earth parking orbit.
After a coast phase lasting about 30 minutes, the upper-stage Centaur performed another eight-minute long nominal burn delivering the payload to a heliocentric – or solar bound, rather than Earthlocked – orbit for the Trans Mars Injection maneuver lining it up to intercept with Mars in February 2021. Upon spacecraft separation and successfully propelling the Perseverance mission onward to Mars, the Centaur upper-stage performed what is called a blowdown maneuver for planetary protection, ensuring that it would miss Mars. Twenty minutes later, the Perseverance spacecraft initiated its transmitter to communicate with Earth, and a good acquisition of signal was received by NASA’s international array of giant radio antennas, the Deep Space Network.
The Perseverance rover and Ingenuity helicopter are expected to continue on the journey to the Red Planet and attempt entry, descent, and landing on February 18, 2020.

SpaceX just launched its secret Starfall saucer again
SpaceX launched its Starfall capsule again on Bandwagon-5, this time listed openly beside rideshare customers.
SpaceX launched its Starfall reentry capsule for the second time on Tuesday morning, flying it as the payload of the Bandwagon-5 rideshare mission. Falcon 9 lifted off from Space Launch Complex 40 in Florida at 7:04 a.m. ET with 32 payloads, and the first stage booster, on its 19th flight, landed on the droneship A Shortfall of Gravitas about nine minutes later.
Starfall was scheduled to separate last, 2 hours and 48 minutes after liftoff. The final customer satellite on SpaceX’s mission timeline comes off the upper stage about an hour and nine minutes in, which left a long gap before the capsule was due to be released alone. SpaceX later posted that the payload deployment sequence is complete. At liftoff, the company said Starfall “enables affordable, routine access to a microgravity environment, providing unique opportunities for on-orbit manufacturing, scientific research, and testing.”

As Teslarati reported before the first Starfall flight, SpaceX made no public announcement about the vehicle then, and nearly everything known came from FAA and FCC filings. This time Starfall is an item name on the official mission page, listed beside paying rideshare customers. SpaceX has still not said what, if anything, is aboard this Starfall, Spaceflight Now noted.
The FAA’s environmental assessment from May describes a disk about 10.2 feet wide and 2.5 feet tall that weighs roughly 4,600 pounds and can bring 2,200 pounds of payload back to Earth.
Interestingly, the same rocket also carries a competitor’s hardware. Varda Space Industries launched its W-Series 7 capsule on Bandwagon-5, a spacecraft about three times smaller than Starfall that will test whether microgravity can improve the solubility of a cancer drug called Protac. It is Varda’s ninth reentry capsule, and W-8 and W-9 launched earlier this month on Transporter-18. SpaceX has been Varda’s launch provider since the company’s first Falcon 9 rideshare contract in 2021.
SpaceX has not published where or how this Starfall will come down. The preview we ran in June described a recovery from the Pacific Ocean, and the company has not said whether this flight follows the same plan. The launch also arrives hours before SpaceX posts its third quarter results after the market closes, a report we previewed earlier this week.

Elon Musk breaks his silence on the Starlink impact to Ukraine drones
Musk says the US military and president set Starshield limits, not SpaceX, amid Ukraine complaints.
Elon Musk says the speed limit cutting out Ukraine’s military Starlink terminals is not SpaceX’s decision. In a post on X Wednesday, Musk wrote that “Starshield systems are owned and controlled by the US government. Any limits on speed or usage are decided by the US military and ultimately POTUS.” He added that Starlink is a commercial service limited to civilian or defensive activities and “cannot be used for offensive military action, as doing so would be inappropriate for a commercial company.”
He was replying to Mykhailo Fedorov, Ukraine’s former defense minister, who had thanked Musk for restoring connectivity at speeds up to 160 km/h and said removing the Starshield limit entirely is “now critical for Ukraine’s defense.”

The complaint started Tuesday night, when Ukrainian officials said military terminals began losing service above roughly 100 mph. Presidential adviser Serhiy Beskrestnov said the defense forces got no warning and several missions were disrupted, as Teslarati reported earlier Wednesday. The 7th Rapid Reaction Corps told Reuters connections dropped for 10 to 20 seconds at speeds well below the limit, which made drones harder to control. Poland’s foreign minister, Radoslaw Sikorski, asked Musk on X whether he is “playing politics with your products again.”
That is why the Starlink and Starshield distinction matters. SpaceX introduced Starshield in 2022 as the government version of Starlink, with an initial focus on Earth observation, communications and hosted payloads. It won a Space Force contract in 2023 with a $70 million ceiling. In December 2024, the Pentagon moved Ukraine’s terminals onto Starshield, covering about 3,000 units across two contracts. Ukraine’s military connections therefore run through a service that Musk now says sits under Washington’s control.
While Musk’s post describes who holds authority, it does not infer that anyone ordered the limit, and neither SpaceX nor the US government has confirmed who set it. Ukrainian officials have pointed to the timing, which follows President Trump’s push for an energy ceasefire and Musk’s Saturday post that “Zelensky has gone too far.” The BBC noted Trump denied threatening to restrict intelligence sharing with Kyiv, and no evidence has been presented that Washington requested the cap.
The episode also revives a promise from 2025. After Poland accused him of threatening Ukraine’s access, Musk said Starlink “will never turn off its terminals” and would not be used as a bargaining chip. Poland has since supplied more than 29,000 terminals to Ukraine. Teslarati also covered Kyiv’s search for Starlink alternatives in 2025, and the latest dispute gives that search new urgency.

SpaceX brings four astronauts home after 8 months in space, and the return was flawless
SpaceX Crew Dragon Freedom returned four Crew-12 astronauts home after 237 days aboard the station.
Four Crew-12 members are back on Earth after 237 days at the International Space Station. SpaceX’s Crew Dragon Freedom splashed down in the Pacific Ocean about 50 miles west of Los Angeles at 11:34 a.m. ET on Thursday.
NASA astronauts Jessica Meir and Jack Hathaway, ESA astronaut Sophie Adenot, and Roscosmos cosmonaut Andrey Fedyaev landed one day after undocking from the station’s Harmony module at 8:05 a.m. ET on Wednesday. NASA confirmed the splashdown minutes later. SpaceX had flagged the 27.5 hour trip home on X while Dragon was still firing its departure burns away from the station.
The descent ran on schedule when Freedom started a nine minute deorbit burn at 10:46 a.m. ET, then hit the thicker atmosphere about 36 minutes later at nearly five miles per second. Chutes deployed at around 18,000 feet, and four main parachutes brought the capsule down to roughly 15 mph at splashdown.
SpaceX fast boats secured Dragon before the recovery ship Shannon hoisted it onto the deck with the crew still inside. Flight surgeons on board ran initial medical checks. All four crew members will be flown ashore by helicopter and then head to NASA’s Johnson Space Center in Houston for rehabilitation.

Crew-12 launched on February 13 from Space Launch Complex 40 at Cape Canaveral, a flight that also marked the first Falcon 9 booster landing at SpaceX’s new LZ-40 pad. Over the mission, the crew completed 3,792 orbits, covered nearly 101 million miles, and carried out four spacewalks to maintain and upgrade the station.
Meir now has 440 cumulative days in space, which places her in NASA’s top 10. This was the first spaceflight for Hathaway and for Adenot, a French Air Force colonel and former helicopter pilot. Fedyaev, who spent 186 days in orbit on Crew-6 in 2023, has now flown two long duration Dragon missions.
The return closes out a busy stretch of Dragon traffic. Crew-13 arrived on October 1 aboard Crew Dragon Grace, which docked just 7 hours and 55 minutes after liftoff, the fastest launch to docking of any U.S. spacecraft in ISS history. Commander Jessica Watkins, pilot Luke Delaney, Canadian Space Agency astronaut Joshua Kutryk, and cosmonaut Sergey Teteryatnikov remain aboard alongside the three person Soyuz MS-29 crew.
With Crew-12 gone, the port is clear for CRS-35, a cargo Dragon carrying the final pair of ISS Roll-Out Solar Arrays. NASA is holding a post-splashdown teleconference at 1:15 p.m. ET covering both the crew’s return and the upcoming cargo launch.
