It's Time for a 2021 Space Flight Round-up

Space is a busy place, with a lot of things going up (most of the time) and coming down (when we want them to). Let’s check in on the latest orbital happenings.

Virgin Galactic

Billionaire Richard Branson’s Virgin Galactic, the spaceflight company that has not conquered the whole “spaceflight” thing just yet, announced the next in line of its fleet: The SpaceShip III Imagine. Imagine doesn’t look much different than its SpaceShip II predecessors, except for the claims by Virgin Galactic that it’s easier to manufacture multiple copies of it. This is supposed to help them reach their goal of 400 suborbital (which means you go up and come down without orbiting the Earth) flights every year. That would be a big step up from its current capacity of their current zero flights per year.

Buckle up! On July 28, Virgin Galactic is showing the world what the inside of their SpaceShipTwo Unity spacecraft looks like via a livestream on their YouTube channel.

Virgin Galactic Failed to Launch because Space is Hard

This is the first test launch from Branson’s Virgin Galactic company since February of 2019, and follows a string of delays, cancellations, and aborts. What’s going on?


What goes up must come down, which SpaceX is learning again and again as it tries to work out the bugs in its newest rocket, the Starship. Elon Musk and team hope that the Starship will be powerful enough to send crews to Mars. Since bugs on a rocket can lead to potential catastrophe, it’s a good thing that they’re testing Starship without anyone on board.

The difficult thing about Starship isn’t the launch itself — which by now for SpaceX is a piece of cake, but the landing. Starship is supposed to be reusable, returning to land safely on the Earth after delivering its cargo beyond the confines of Earth’s gravity. But in order to make it work on such a massive craft before it lands, it has to flip itself from horizontal to vertical right before landing which has proven to be difficult. The last attempt, on March 30, failed because of a methane leak in one of the engines.

SpaceX vs. the Universe

Fans of space are having a tough time picking sides over a recent controversy between SpaceX and astronomers. But what's the big debate all about? Astrophysicist Paul M. Sutter digs into both perspectives.

SpaceX Test Flight Ends in Explosion

An experimental rocket launched by SpaceX on Wednesday, December 9 exploded after launching 8 miles into the air. Elon Musk says that this test was still a success.


It's a good thing that NASA didn't contract to use the Starship yet, and instead stuck to the tried-and-true Falcon 9 for its April 23rd launch of a crew to the International Space Station. This was the second crew launch with SpaceX, following last summer’s historic use of a private company for delivery of humans to the station. Those folks will be hitching a ride back home on a SpaceX capsule and the splashdown is currently scheduled for Sunday, May 2 around 2:53A ET.

In robotic explorer news, “Percy”, the adorable nickname for NASA’s Perseverance rover on Mars, has begun taking data after a successful (if scary) landing on the red planet. As an added bonus, Percy’s little friend, Ingenuity, recently detached from the rover and settled on the surface. Ingenuity is a drone aircraft specifically designed to work in the thin Martian atmosphere, and will begin its first test flight soon. If successful, it will be the first powered flight on another world in the history of humanity. The Wright brothers would be proud.

NASA's long-awaited Artemis 1 uncrewed moon mission and next generation of spacecraft has been delayed for a second time. The rocket was initially scheduled to launch on Aug. 29, 2022, at 8:33 AM ET, but was delayed due to an issue with the engine bleed.

What We Learn from the Lunar Surface

Sure, the Moon is cool to look at, and fun to think about it. And it literally affects us here on the Earth: without the Moon, we’d be missing half our tides, and likely our planet’s rotation wouldn’t be as stable as it is.
