New SpaceX Raptor Engine Beats the Chamber Pressure of Russia’s RD-180 Engine, According to Elon Musk

2019 has been shaping up to be an interesting year for SpaceX and its founder, Elon Musk. After completing work on the miniaturized version of the Starship (Starship Alpha or “Starship hopper”) over the holidays, SpaceX moved ahead with the test-firing of its new Raptor engine in late January/early February. In accordance with Musk’s vision, these engines will give the Starship the necessary thrust to reach the Moon and Mars.

The test-firing took place at SpaceX’s Rocket Development and Test Facility, located just outside of McGregor, Texas. As Musk recently tweeted, the tests went very well, achieving the thrust necessary for both the Starship and its first-stage booster, the Super-Heavy. Musk also claimed that the engine broke the previous record for combustion chamber pressure, which was established by the Russian RD-180.

Elon Musk’s New Plan is to Get to the Moon as Fast as Possible

For Elon Musk and SpaceX, the company he founded to reignite space exploration, a great deal hinges on the creation of the Starship. This super-heavy launch vehicle, which was has evolved considerably in the past few years, will eventually replace the Falcon 9 and Falcon Heavy as the mainstay of the SpaceX fleet. Once operational, it will also facilitate missions to the Moon and eventually Mars.

Once again, Elon Musk has used his social media platform of choice to share the latest details about the Starship‘s progress. As he shared in a series of tweets, which began on Thursday, Jan. 31st, the company has commenced test-firing the Raptor engine at their Rocket Development and Test Facility in McGregor, Texas, and is pushing towards the Starship’s first mission.

In an announcement sure to make you quiver with delight, Elon Musk says that SpaceX could begin short-hop test flights of its Starship prototype as early as next Spring. The Starship, which looks like something from a 1950’s sci-fi novel cover (awesome!) is intended to carry people to the Moon and Mars. When the spacecraft design was originally announced in 2016, it was called the Mars Colonial Transporter, and it sent shockwaves through the community.

Now, it’s almost test-flight time.

The SpaceX Starhopper has Three Raptor Engines on the Bottom

This year, SpaceX will test out a miniaturized version of its super-heavy launch vehicle, which is known as the Starship (aka. the Big Falcon Rocket). This test launch will validate the design of the rocket and how it fairs at supersonic speeds and deals with the cryogenic environment of space. It will also serve as an opportunity to conduct the delivery of the next batch of SpaceX’s Starlink satellites.

Recently, Musk tweeted images of sections of the mini-Starship (Starship Alpha, the Starship hopper) being brought out at the company’s South Texas Launch Site in Boca Chica, Texas, for assembly. From the latest images that have been shared by multiple sources, it is clear that SpaceX crews have been working round the clock and through the holidays to get the hopper ready for its test flight later this year.

Prototype Version of the SpaceX Starship with a Stainless Steel Skin is Under Construction

Elon Musk has been a busy man in recent years. In September of 2016, he unveiled his company’s plan for a super-heavy launch vehicle – the Interplanetary Transport System (ITS). The following year, Musk presented the world with an updated design of the vehicle, which had been renamed the Big Falcon Rocket (BFR) and the Big Falcon Spacecraft (BFS). This past November, the launch system was renamed yet again to the Starship.

Musk also recently indicated that his company would be building a smaller version of the Starship to test the design. As the mission architecture has evolved, Musk has kept the public apprised of the progress of the ship’s construction. As usual, the latest update was provided via Twitter, where Musk shared images of the pieces of the mini-Starship ( aka. Starship Alpha) being rolled out in preparation for construction.

Good News: a SpaceX Cargo Resupply is Off to the Space Station. Bad News: Failed Hydraulics in the Grid Fins Caused the First Stage Booster to Crash Into the Ocean

It’s been a busy time for Elon Musk and SpaceX, lately. Earlier this week, the company launched 64 satellites (and a art project known as the Orbital Reflector) in what was the largest rideshare mission in history. The mission was also historic because it involved a booster making its third successful landing. And this was after Musk released more details about his proposed BFR, henceforth known as the “Starship

And earlier today (Wednesday Dec. 5th), SpaceX launched its sixteenth Commercial Resupply Services mission (CRS-16) to the International Space Station (ISS). While the deployment of the Dragon spacecraft was successful, the first stage booster did not make it back to the landing pad. After suffering from an apparent malfunction in one of its grid fins, the booster fell into the sea – but remained intact and will be retrieved.

SpaceX Uses a Thrice-Launched Booster to Send 64 Satellites Into Space.

Earlier today (Monday, Dec. 3rd), private aerospace giant SpaceX launched its Spaceflight SSO-A: SmallSat Express mission. The launch took place from Space Launch Complex 4E (SLC-4E) at Vandenberg Air Force Base in California. Aboard the rocket were 64 spacecraft, consisting of microsatellites, cubesates, technology demonstrators and educational research endeavors.

This mission was a milestones for a number of reasons. For Spaceflight Industries, which arranged for the cargo to be delivered to a Sun-Synchronous Low Earth Orbit (SSO), it was the largest single rideshare to be launched from US soil. For SpaceX, it was the third time that the rocket’s first stage booster had been launched and retrieved, bringing us ever closer to the day when Elon Musk’s vision of completely reusable rockets becomes a reality.

Name Change Alert! SpaceX’s BFR is Now Just Called “Starship”

In September of 2016, Musk treated the world to an early sneak-peak at his proposed super-heavy launch vehicle. Previously known as the Mars Colonial Transporter, the renamed Interplanetary Transport System (ITS) was the centerpiece to Musk’s long-term vision of conducting commercial trips to orbit, to the Moon, and even to Mars. Since that time, the mission architecture and even the name of the system have changed a few times.

For example, in September of 2017 – during a presentation titled “Making Life Interplanetary” – Musk presented the world with an updated design of launch system, which had been renamed the Big Falcon Rocket (BFR) and the Big Falcon Spacecraft (BFS). And just recently, Musk announced the system will henceforth be known as the “Starship”, and its rocket the “Super Heavy“.

SpaceX Gives More Details on how their Starlink Internet Service Will Work. Less Satellites, Lower Orbit, Shorter Transmission times, Shorter Lifespans

For years, Elon Musk has talked about his plans to provide broadband internet access to the world using a constellation of satellites. Known as Starlink, this constellation was originally going to of nearly 12,000 low-cost satellites providing a terabit internet service. The first batch of these satellites is scheduled to launch in June of 2019, with the full constellation being deployed by the mid-2020s.

While the bare bones of this plan have been public knowledge for some time, Musk and the company he founded to reinvigorate space exploration have been somewhat scant on the details. But thanks to a simulation created by Prof. Mark Handley of University College London, the world may finally get an idea of what Starlink might look like.

SpaceX is going to build a mini-BFR to launch on a Falcon 9

In September of 2016, Elon Musk unveiled his vision for a super-heavy launch vehicle, which would be SpaceX’s most ambitious project to date. Known as the Big Falcon Rocket (BFR), this massive launch vehicle is central to Musk’s plan of conducting space tourism with flights into orbit and to the Moon. It is also intrinsic to his vision of sending astronauts and colonists to Mars.

Ever since, the astronomical and aerospace community has been paying close attention to any updates provided by Musk on the BFR’s development. In his latest update, which was made via Twitter, Musk indicated that his company will be building a small, winged version of the massive spaceship component – the Big Falcon Spaceship (BFS) – which will be launch-tested using a Falcon 9 or Falcon Heavy rocket.
