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.

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. 15th), 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.

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.

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 20th, 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.

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.

The reason people use the aphorism “it isn’t rocket science” is because rocket science is hard. Virgin Orbit, a spin-off of Virgin Galactic that focuses on small satellite launches, proved that with a recent test of its LauncherOne rocket.

This week, European engineers hot-fire tested a fully 3D-printed thrust chamber that could one day power the upper stages for rockets. The chamber has just three parts, and was constructed using additive layer manufacturing, another name for 3D printing.
This hot-fire test lasted 30 seconds and was carried out on May 26, 2020 at the DLR German Aerospace Center’s Lampoldshausen testing facility. The European Space Agency said that additional tests are planned for next week.

I always remember hearing the comparison of how the Space Shuttle’s main engines would drain an average family swimming pool in under 25 seconds. Or that the Saturn V used the equivalent of 763 elephants of fuel. But just how much fuel does a rocket burn during its ascent to orbit? As you might expect, the amount varies with different rockets.
A great new video provides an incredible visual of how much fuel is burned by four different rockets, from launch to the various stage separations by showing what rocket launches would look like if the rockets were completely transparent.

China’s next-generation crewed spacecraft, which will replace the venerable Shenzou spacecraft in the coming years, recently returned to Earth after spending almost three days in space. The purpose of this mission was to test the deep space capabilities of the spacecraft that will be sending Chinese astronauts (taikonauts) to orbit, to the Moon, and beyond in the coming years.
In addition, this mission also saw China’s new Long March 5B (CZ-5B) heavy-lift rocket launch a payload to space for the first time. This rocket is the latest installment in the Long March family and will be vital to the creation of the third and largest Chinese space station. These two milestones have brought China a step closer to becoming a full-fledged superpower in space.

In the summer of 2017, the company Rocket Lab officially tossed its hat into the commercial aerospace (aka. NewSpace) ring with the first test flights of their two-stage Electron Rocket. Dedicated to providing cost-effective launch services for the small satellite market, the company began conducting commercial launches from their complexes in New Zealand and California using the lightweight Electron.
Looking to cut the costs associated with individual launches further, Rocket Lab has decided to pursue reusability as well. In early March, before the isolation orders were issued, the company achieved a major milestone when it conducted a successful mid-air recovery of the test stage of an Electron Rocket – which involved a helicopter catching the test stage after its parachute deployed.
