South Korea Launches its First Rocket. The Third Stage cut off Short.

So far, only six countries have successfully launched more than 1 ton of equipment into space using domestically developed rockets. A seventh, North Korea, has successfully done so with a slightly smaller payload. Recently, their southern neighbor attempted to get into this exclusive club by testing its first-ever three-stage orbital rocket.

Lightweight Carbon Fiber Reinforced Plastic Fuel Tanks Pass a Critical Test, and Could Knock a lot of Weight off a Rocket’s dry Mass

Material science is still the unsung hero of space exploration. Rockets are flashier, and control systems more precise, but they are useless without materials that withstand the immense temperatures of forces required to get people and things off the planet. Now a team from MT Aerospace, working on a grant from ESA, has developed a new type of material that will be immensely useful in one of the most important parts of any rocket engine – the fuel tanks.

Relativity Space Gets a Huge Investment to Take on SpaceX With Reusable Rockets

They say imitation is the sincerest form of flattery, and that competition is a great way to foster progress and innovation. If these truisms are to be believed, then the NewSpace industry is destined to benefit from the presence of Relativity Space, a commercial space company based in Los Angeles. At the same time, SpaceX founder Elon Musk should be flattered that Tim Ellis and Jordan Noone (founders of Relativity Space) are following his example.

Roughly six years ago, Ellis and Noone founded Relativity for the purpose of using new technologies to disrupt the aerospace industry. Earlier this week (Tuesday, June 8th), the company announced that it had raised an additional $650 million in private capital. This money will go towards the development of rockets that are entirely 3D-printed and fully reusable, as well as the creation of a new class of heavy launch vehicles known as the “Terran-R.”

In a Comprehensive new Test, the EmDrive Fails to Generate any Thrust

The EmDrive is a hypothetical rocket that proponents claim can generate thrust with no exhaust. This would violate all known physics. In 2016, a team at NASA’s Eagleworks lab claimed to measure thrust from an EmDrive device, the news of which caused quite a stir. The latest attempt to replicate the shocking results has resulted in a simple answer: the Eagleworks measurement was from heating of the engine mount, not any new physics.

China’s Super-Heavy Lift Rocket Will Carry 100 Tons to the Moon

China’s proposed next-generation rocket reached the final stage of feasibility studies this month. The planned launch vehicle, known as the Long March-9, will be capable of sending 100 tons to the Moon, and could see its first launch as early as 2030.

Announced in 2018, the Long March-9 will play a key role in China’s long-term space ambitions. If all goes as planned, its first payload is likely to be a Martian sample return mission, and it would support China’s Lunar ambitions as well. Another proposed use for the super-heavy lift vehicle is to build an experimental space-based solar power station, although plans for that project are still very tentative.

ESA is Working on its own Reusable Booster Stage

It’s an exciting time for space exploration! All around the world, national space agencies are sending missions to deep-space and preparing to send astronauts to orbit and the Moon. At the same time, the commercial aerospace industry (NewSpace) is expanding to include more launch providers and service new markets. These developments are adding up and making space more cost-effective and accessible.

One such development of the emergence of reusable rockets, which are reducing the cost of individuals launches down considerably. Earlier this month (Dec. 15^th), the European Space Agency (ESA) contracted with aerospace giant ArianeGroup to develop a reusable rocket. As part of the Themis Program, the ESA will use this rocket to evaluate the technologies involved for potential use on future European launch vehicles.

RocketLab Recovers a First-Stage Booster for the First Time: “Return to Sender”

In recent years, one of the most impressive developments for space exploration has been the rise of the commercial space industry (aka. NewSpace). Beyond fulfilling contracts with space agencies like NASA to provide commercial and crewed launch services, private aerospace companies are also fostering innovation that is helping to reduce the cost of sending payloads to space.

Take RocketLab, the US/NZ-based small satellite launch company that has broken new ground with its Electron rocket. In a further bid to reduce the costs of individual launches, RocketLab announced last year that it would begin recovering and reusing the spent boosters of its rockets. Recently, the company took a big step by successfully retrieving the first stage of an Electron after it delivered a payload to orbit.

SpaceX Starship Passes Static Fire Test With Three Raptor Engines, Finally Gets Nose Cone!

It’s beginning to look like SpaceX will attempt to make the 15 km (9.3 mi) hop test before Christmas! After two successful 150 m (~500 ft) hops with the SN5 and SN6 prototypes, engineers at SpaceX’s Boca Chica launch facility in South Texas rolled out the SN8 – the first Starship prototype to have three Raptor engines. But before the SN8 can conduct a high-altitude test flight, the engineers needed to run a static fire test.

This test is crucial to ensuring that the Starship‘s interior plumbing can handle its cryogenic propellants, and is the last milestone before the Starship can conduct a high-altitude flight. On the evening of Tuesday, October 20^th, that’s exactly what they did! At 3:13 AM local time (01:13 AM PDT; 04:13 AM EDT), the SN8 fired up its three Raptor engines and kept firing them for several seconds straight.

Electron Rocket’s 13th Launch Failed, Destroying its Satellite Payload

This past weekend (June 5th), the California and New Zealand-based aerospace company Rocket Lab suffered a terrible accident. During the 13th launch of their Electron rocket, an anomaly caused the second stage of the rocket to explode in midair. Luckily, there were no injuries, but the explosion did claim the mission payload, which consisted of satellites and commercial payloads for three different companies.
