Starship’s Booster (and Donald Trump) Make a Splash With Sixth Flight Test

SpaceX’s Starship launch system went through its sixth flight test today, and although the Super Heavy booster missed out on being caught back at its launch pad, the mission checked off a key test objective with President-elect Donald Trump in the audience.

Trump attended the launch at SpaceX’s Starbase complex in the company of SpaceX CEO Elon Musk, who has been serving as a close adviser to the once and future president over the past few months. In a pre-launch posting to his Truth Social media platform, Trump wished good luck to “Elon Musk and the Great Patriots involved in this incredible project.”

The New Mars Landing Approach: How We’ll Land Large Payloads on the Red Planet

Back in 2007, I talked with Rob Manning, engineer extraordinaire at the Jet Propulsion Laboratory, and he told me something shocking. Even though he had successfully led the entry, descent, and landing (EDL) teams for three Mars rover missions, he said the prospect of landing a human mission on the Red Planet might be impossible.

But now, after nearly 20 years of work and research — as well as more successful Mars rover landings — Manning says the outlook has vastly improved.

“We’ve made huge progress since 2007,” Manning told me when we chatted a few weeks ago in 2024. “It’s interesting how its evolved, but the fundamental challenges we had in 2007 haven’t gone away, they’ve just morphed.”

SpaceX’s Mechazilla Catches a Starship Booster on First Try

For the first time ever, SpaceX has followed through on a Starship test launch by bringing back the Super Heavy booster for an on-target catch in the arms of its “Mechazilla” launch-tower cradle in Texas.

“This is a day for the engineering history books,” SpaceX launch commentator Kate Tice said.

Today’s successful catch marks a giant step toward using — and reusing — Starship for missions ranging from satellite deployments to NASA’s moon missions to migrations to Mars.

On June 6th, 2024, the fourth orbital test flight of the Starship successfully lifted off at 07:50 a.m. CT (08:50 a.m. EDT; 06:50 PDT) from SpaceX’s Starbase in Texas. This test was the first time the Starship (SN29) and Super Heavy (BN11) prototypes reentered Earth’s atmosphere and landed successfully. While the SN29 conducted a powered vertical landing before splashing down in the Indian Ocean, the BN11 executed a similar powered landing before splashing down in the Gulf of Mexico. In a recent tweet, Elon Musk shared a photo of the BN11 booster being pulled out of the sea.

On Tuesday, September 10th, at 5:23 a.m. EST (03:23 p.m. PST), the Polaris Dawn mission launched from NASA’s Kennedy Space Center in Florida, carrying a crew of four to Low Earth Orbit (LEO). This mission is the first of three that comprise the Polaris Program, a private spaceflight program organized by entrepreneur and private astronaut Jared Isaacman and financed by SpaceX. Since launching, the Resilience Crew Dragon spacecraft has flown higher than any crewed mission since the Apollo Era and passed through parts of the Van Allen radiation belt.

Earlier today, the crew carried out the first private spacewalk in the history of spaceflight!

Starlink Direct-to-Cell Satellites are Coming. What Will Be Their Impact on Astronomy?

Mention the name Starlink among the astronomy community and you will often be greeted with a shudder. There are now thousands of Starlink satellites orbiting Earth providing internet connectivity to every corner of the Earth. Many believe they are making astronomy difficult but now, SpaceX is launching another service; ‘direct-to-cell’ technology that will allow mobile phones to use satellites to send text messages as early as this year. Voice and data services are likely to follow on quickly next year. With smaller antennae at a lower altitude what is their impact on astronomy?

SpaceX Resumes Falcon 9 Rocket Launches After FAA Go-Ahead

SpaceX is flying again after the Federal Aviation Administration ruled that the company can resume Falcon 9 rocket launches while the investigation into a failed July 11 mission continues.

The FAA’s go-ahead came on July 25 after SpaceX reported that the failure was caused by a crack in a sense line for a pressure sensor attached to the upper stage’s liquid-oxygen system. That resulted in an oxygen leak that degraded the performance of the upper-stage engine. As a near-term fix, SpaceX is removing the sense line and the sensors for upcoming Falcon 9 launches.

It didn’t take long for SpaceX to get back to its flight schedule. The company launched a Falcon 9 rocket from NASA’s Kennedy Space Center in Florida at 1:45 a.m. ET (05:45 GMT) today. Like the July 11 mission, this one sent a batch of SpaceX’s Starlink satellites to low Earth orbit.

The launch appeared to proceed without incident. After stage separation, the first-stage booster descended to a landing on a drone ship in the Atlantic Ocean, while the second stage proceeded to orbit and deployed 23 satellites for the Starlink high-speed internet network.

SpaceX Reveals the Beefed-Up Dragon That Will De-Orbit the ISS

The International Space Station (ISS) has been continuously orbiting Earth for more than 25 years and has been visited by over 270 astronauts, cosmonauts, and commercial astronauts. In January 2031, a special spacecraft designed by SpaceX – aka. The U.S. Deorbit Vehicle – will lower the station’s orbit until it enters our atmosphere and lands in the South Pacific. On July 17th, NASA held a live press conference where it released details about the process, including a first glance at the modified SpaceX Dragon responsible for deorbiting the ISS.

SpaceX’s Rocket Failure Could Cause Delays for Lots of Launches

After going eight years and more than 300 launches without a failure, SpaceX had a Falcon 9 rocket launch go awry, resulting in the expected loss of 20 Starlink satellites.

The Federal Aviation Administration said it would oversee an investigation into the anomaly, raising the prospect that dozens of launches could be delayed until the problem is identified and rectified. Update for July 27: SpaceX was able to resume Falcon 9 launches after the FAA ruled that no public safety issues were involved in the anomaly.

As many as 40 Falcon 9 launches are on tap between now and the end of the year — potentially including missions that would carry astronauts to the International Space Station and send the privately funded Polaris Dawn crew into orbit for the world’s first commercial spacewalk.

Astronauts are Practicing Lunar Operations in New Space Suits

Through the Artemis Program, NASA will send astronauts to the lunar surface for the first time since 1972. While the challenges remain the same, the equipment has evolved, including the rocket, spacecraft, human landing system (HLS), and space suits. In preparation for Artemis III (planned for September 2026), NASA recently conducted a test where astronauts donned the new space suits developed by Axiom Space and practiced interacting with the hardware that will take them to the Moon.
