SpaceX

SpaceX managed a record 31 launches in 2021, but its more-than-weekly pace in 2022 including a launch Sunday morning let it match that record less than seven months into the year.

A Falcon 9 rocket carrying 53 more of its Starlink internet satellites to orbit lifted off from Cape Canaveral Space Force Station's Space Launch Complex 40 at 10:20 a.m. Eastern Time.

This is the third time SpaceX used a first-stage booster for a record 13th time, with this booster having previously flown on Crew Dragon's first demonstration mission, the RADARSAT Constellation Mission, SXM-7 and nine Starlink missions. It's notably also been used at all three of SpaceX's launch facilities, having also taken off from Kennedy Space Center and Vandenberg Space Force Base on missions responsible for bringing nearly 600 payloads to .

The majority of this year's launches have been in support of the growing Starlink internet constellation, which is now active in around 40 markets around the world. This marks the 17th Starlink launch of the year and 52nd Starlink launch since the first operational deployment in 2019, with more than 2,800 satellites sent to orbit.

The 570-pound satellites orbit at around 341 miles altitude.

The technical achievements of deploying JWST and the anticipation about its first images have overcome what JWST had been known for: billions of dollars in cost overruns and years of schedule delays.

To get artificial gravity on the moon, you'd need a giant rotating lunar base

Living and working in space for extended periods of time presents a number of challenges. These include radiation, as locations beyond Earth's protective magnetosphere are exposed to greater levels of solar and cosmic rays. There's also the need for self-sufficiency since lunar or Martian bases are too far to rely on regular resupply missions like the International Space Station (ISS). Last, there's the issue of low gravity, which is especially pressing for long-term missions and habitats beyond Earth. If humanity's future truly lies in space, we must devise solutions to this issue in advance.

A popular idea is to create rotating habitats in space that simulate , like the Pinwheel Station or the O'Neill Cylinder. Another proposal by a team of Japanese researchers calls for something bolder: a rotating habitat on the moon. On July 5, representatives from Kyoto University and the Kajima Corporation (one of the oldest and largest construction companies in Japan) announced that they would be partnering to conduct a study on this concept and how it could make humanity's plans for living on the moon and Mars a reality.

How does reduced gravity affect astronauts' muscles and nerve responses?

Among the many functions performed by skeletal muscles, an important one is maintaining our posture. If it weren't for these muscles, Earth's gravitational pull may make it difficult for us to stand and walk around. The group of muscles—mostly present in our limbs, back, and neck—which are responsible for maintaining our posture and allowing us to move against the force of gravity are rightly called "anti-gravity" muscles.

But what happens to these muscles when there is no gravity (or an "unloading" of gravitational force) for them to work against? The question might sound ridiculous to some, but not to an astronaut aboard the International Space Station (ISS). In , where gravity is minimal, our muscles (especially the anti-gravitational ones) are not used as much, which might result in their atrophy and changes to their structure and properties. In fact, human calf muscles are known to reduce in volume during a flight in space.

For years, Paul Meyer's job in the U.S. Air Force was to suppress enemy air defenses. To do that, he had to know where they were and what they were doing. And to do that, he and the pilot of his F-4 Phantom II had to get close enough to show up on their radars. "My job was to play chicken - to put myself in that environment where I have to fire my missile before he fires his," said Meyer,
