The 2026 MLB season has surpassed the quarter mark, and after each team’s first 40 games, there’s plenty of reasons to tune in all summer long.

Chicago White Sox slugger Munetaka Murakami has already proven doubters wrong by launching 17 home runs, Pittsburgh’s Paul Skenes consistently looks like the best version of himself on the mound and Milwaukee ace Jacob Misiorowski is throwing harder than any starter in the majors.

The MLB action continues on Thursday as the Arizona Diamondbacks visit the St. Louis Cardinals.

Here’s everything you need to know to tune in for the first pitch.

First pitch between the St. Louis Cardinals and Arizona Diamondbacks is scheduled for 7:45 p.m. (ET) on Thursday, June 25.

How to watch Arizona Diamondbacks vs St. Louis Cardinals on Thursday

The Swift Observatory has been scanning the cosmos for more than two decades while orbiting Earth. But in recent years, NASA has noticed that the crucial satellite has been unexpectedly getting lower and lower – putting it in danger of burning up in Earth’s atmosphere.

Now, the U.S. space agency is on the cusp of mounting a rescue mission later in June – the likes of which has never before been attempted – that stunningly came together in less than a year.

The daring venture has recently reached the final stages, with the spacecraft that will fly in orbit – manufactured by an Arizona aerospace company – being mated with the rocket and the aircraft that will deploy it to orbit. If all goes to plan, the mission will soon send the spacecraft on a trajectory to intercept NASA’s telescope and reverse its decaying orbit by boosting it to a higher altitude, extending the observatory’s life.

Here’s what to know about the mission, and Arizona’s integral role in ensuring everything came together to save the observatory in time.

What is the Swift Observatory?

Launched in 2004, NASA’s Swift Observatory has spent more than two decades orbiting Earth while studying a variety of cosmic phenomena. The satellite’s primary objective, though, is to observe gamma-ray bursts – events triggered by the catastrophic deaths of massive stars and considered to be the most powerful types of explosions in the universe.

The satellite is equipped with three multiwavelength telescopes that are able to collect data in visible, ultraviolet, X-ray and gamma-ray light.

Swift space telescope falls faster to Earth than expected

NASA to mount rescue mission for vital space telescope named Swift

NASA and commercial partners will launch a spacecraft in June to boost Swift Observatory’s orbit, staving off its destruction and extending its life.

The Swift Observatory is in a region of space known as low-Earth orbit nearer to the atmosphere, which is also where the International Space Station resides.

All spacecraft in that region can expect to fall to lower altitudes if they don’t have propulsion systems to counteract atmospheric drag and maintain their orbits. But the Swift Observatory has fallen faster than NASA has anticipated because of increased solar storms since fall 2024.

NASA plans mission to rescue Swift

NASA could allow the Swift Observatory to fall back to Earth, where it would harmlessly burn up as it careened into the atmosphere.

Instead, the space agency is planning a mission to rescue the telescope and extend its mission for several more years.

A successful mission would mark the first time that a commercial robotic spacecraft captured a government satellite that – unlike other spacecraft like the Hubble Space Telescope – was never meant to be serviced in space. The unprecedented venture, NASA leaders say, would also test a new capability that could be used on other missions while negating the need to spend even more money to replace the observatory.

To accomplish the risky feat, NASA will need a spacecraft designed to capture and raise the orbit of the Swift Observatory, and a rocket to launch it into space, according to the agency. In the meantime, mission teams on the ground are keeping Swift at least 185 miles above Earth, where the boost mission has the best chance of success, NASA said.

Arizona aerospace company races to develop rescue spacecraft

The spacecraft that will attempt to rescue the Swift Observatory was developed by Katalyst Space, an aerospace company based in Flagstaff, Arizona, which was awarded the $30 million contract in September 2025.

With less than a year to help NASA mount a rescue mission, Katalyst developed the LINK robotic servicing spacecraft intended to latch onto a space telescope that was never meant to be captured.

Because Swift has no docking ports or grappling fixtures to grab onto, Katalyst built LINK with a custom robotic capture mechanism that will attach to a feature on the satellite’s main structure. The process is meant to mitigate the chance of any sensitive instruments being damaged, Katalyst said in a press release.

Why such a quick turnaround? Because Swift is falling – and falling fast.

According to Katalyst, the satellite has a 50% chance of making an uncontrolled reentry by mid-2026 without intervention, with those odds increasing to 90% by the end of 2026.

Northrop Grumman to launch LINK spacecraft

LINK will hitch a ride to space with a rocket manufactured by Northrop Grumman, a Virginia-based aerospace and defense company. At about 55 feet tall, Northrop Grumman’s Pegasus XL is classified as a small-lift rocket regarded as the world’s first privately developed orbital launch vehicle.

In mid-June, LINK was securely encapsulated in a payload fairing inside the Pegasus XL rocket at NASA’s Wallops Flight Facility in Virginia, according to Katalyst.

The Pegasus XL was also attached around the same time to the belly of Northrop Grumman’s Stargazer aircraft tasked with deploying the rocket, NASA said in a press release. The Stargazer aircraft then took off June 18 from Wallops bound for the Marshall Islands, where the mission is due to commence.

When, where is launch?

The Pegasus XL rocket is due to launch later in June from the Kwajalein Atoll in the Marshall Islands, located in the South Pacific Ocean between Hawaii and the Philippines, according to NASA.

Rather than get the rocket off the ground vertically on a launch pad, Northrop Grumman deploys an air-launch strategy to send the Pegasus to space. The approach will require the company’s Stargazer L-1011 aircraft to take off and climb to approximately 40,000 feet over the ocean, where Pegasus will be released.

After several seconds in free-fall, the Pegasus XL will then ignite the first of its three-stage rocket motors, delivering LINK into orbit in about 10 minutes, according to Northrop Grumman.
