Space may be the last frontier, but there’s nothing “final” about developing new and more cost-effective ways to get there. Whether you have your sights on Mars, delivering payloads to the International Space Station (ISS) or sending satellites into geosynchronous orbit, it all starts with the launch system.

You’ll learn a lot about these important systems – including the latest developments and opportunities in the emerging launch market – at TC Sessions: Space 2021 14-15 December. buy your pass now And save $100.

All payloads, such as satellites, spacecraft, astronauts or supplies destined for the ISS, require rockets with sufficient propellant to launch and deliver them safely to their intended destinations. But it’s not that simple: the scale and type of launch system varies depending on the destination (thanks, Captain Obvious).


To achieve orbit, a launch vehicle must hit a minimum velocity of 17,500 mph. Flying to the Moon or Mars requires a top speed of at least 25,000 mph. The enormous amount of propellant needed to accomplish those speeds means that the structural weight of the launch vehicle must be kept to a minimum. And that’s without getting into the reusable launch stages.

Without a launch system there are no payloads – no Earth observation satellites measuring the environment and atmospheric patterns, which inform air traffic control and autonomous land transport or search and rescue capabilities. There is no telecommunications or radio navigation system to provide accurate positioning for satellite constellations.

It’s safe to say that designing more fuel- and weight-efficient launch systems to more cost-effectively deliver payloads is essential to a sustainable space economy and an area of ​​opportunity for early-stage space startups.

Most space people are well aware of the incredible achievements of both SpaceX (it has just successfully launched fourth crew mission for NASA) and Rocket Lab (who plans to launch two commercial Earth-observing satellites on a two-stage Electron rocket). But it also pays to keep an eye on the ups and downs — and you’ll meet them in TC Sessions: Space 2021.

Here is a prime example. Don’t miss a panel discussion with “The New Kids on the Launch Block” Max Hotel (launcher), Benjamin Lyon (Astra) and lauren leone (Firefly Aerospace). These launch leaders will talk about opportunities in the changing launch market and how they are prepared to take advantage of it.
