How tall is super heavy?

Super Heavy alone stands 230 feet (70 meters) tall and Starship SN4 added another 165 feet (50 m) of height. Together they stood a whopping 395 feet tall (120 m), taller than NASA's massive Saturn V moon rocket, which was 363 feet tall (110 m). "Dream come true," Musk wrote on Twitter of the stacked Starship. space.comSpaceX stacks Starship atop massive booster for 1st time to make the world's tallest rocket

When is Super Heavy launch?

The Space Launch System (SLS) is a US government super heavy-lift expendable launch vehicle, which has been under development by NASA in a well-funded program for nearly a decade, and is currently slated to make its first flight on November 4, 2021. wikipedia.orgSuper heavy-lift launch vehicle

The rocket company posted jabs at SpaceX and NASA online after NASA snubbed its lunar lander.

Blue Origin previously fired shots at Virgin Galactic.

Blue Origin, the rocket company founded by Jeff Bezos in 2000, is being salty online after NASA snubbed it for a contract to land astronauts on the moon.

Instead, NASA chose SpaceX to put the first boots on the lunar surface since 1972. It awarded the company, which Elon Musk founded in 2002, an exclusive contract to turn its Starship vehicle into a lunar lander.

In response, Blue Origin called Starship "immensely complex and high-risk" and said NASA made the "wrong" decision. The company recently updated its website to include a graphic that compares Starship unfavorably to Blue Origin's Blue Moon lunar lander.

Blue Origin appears to be, at minimum, cherry picking its comparisons. The graphic notes that the Starship-Super Heavy system hasn't launched yet. Starship has launched six miles into the air on several occasions, but not with its Super Heavy booster. It also points out that SpaceX's Starship facilities in Boca Chica, Texas have never accommodated an orbital launch. Blue Origin, though has never launched any rocket to orbit from anywhere.

The graphic doesn't, however, note the cost of the Starship lunar lander. SpaceX's proposal estimates that it will cost NASA $2.9 billion, while Blue Origin's gave a price of $5.9 billion.

NASA was originally expected to award contracts to two companies, but cited a lack of funding from Congress in its decision to give SpaceX the sole contract in April. Blue Origin and Dynetics, another competitor for the contract, filed formal protests. Those complaints forced SpaceX to pause work on its Starship lunar lander.

Bezos, who flew to the edge of space aboard Blue Origin's New Shepard rocket last month, even offered to pay for $2 billion of the project if NASA would award his company a contract.

Still, NASA declined. The US Government Accountability Office upheld NASA's decision and turned down the protests on Friday.

Shortly afterwards, Blue Origin published its new graphic. But it wasn't the first time the company has put out infographics criticizing its competitors.

Blue Origin pioneered this new method of promoting itself (and knocking competitors) last month.

A few weeks after Bezos revealed that he planned to fly to the edge of space, Virgin Galactic founder Richard Branson announced that he'd be going aboard his own company's space plane - with liftoff scheduled just nine days before Bezos. Shortly before Branson's flight, Blue Origin posted a chart comparing the two flights on Twitter. The graphic points out that New Shepard has bigger windows and flies higher than Virgin Galactic's space plane.

Still, even though Branson beat Bezos to the edge of space, the Amazon founder has a special rivalry with Elon Musk. The two have similar ambitions - to establish human settlements in space - but have sparred over their competing companies since 2013, when SpaceX tried to get exclusive use of a NASA launchpad and Blue Origin filed a protest. The companies have also battled over patents, and Bezos and Musk have made repeated jabs at one another on Twitter and in media interviews.

Now, SpaceX is becoming a NASA favorite. Its Crew Dragon spaceship is regularly ferrying astronauts to and from the International Space Station. Just three days after Bezos's launch, the agency awarded SpaceX a $178 million contract to launch its mission to Jupiter's ocean moon Europa.

Blue Origin, meanwhile, hasn't yet launched a rocket to orbit. Its vehicles can skim the edge of space for a few minutes before falling back down, but they aren't strong enough to push themselves to orbital heights.

Blue Origin - which Bezos has called his "most important work" - published more than the graphic. On the same webpage, Blue Origin also put up three single-page letters criticizing NASA's decision and pleading with Congress to make the agency pick a second provider for its lunar lander.

The letters say that NASA's process was "flawed," "inconsistent," "unfair," and "ignored the significant risks" of choosing just one provider.

Blue Origin said that for SpaceX's Starship to land on the moon, it would need to perform a range of unprecedented, and therefore risky, processes.

SpaceX has achieved another major milestone in its Starship fully reusable launch system: It stacked the Starship spacecraft itself on top of a prototype of its Super Heavy booster, which itself is loaded up with a full complement of 29 Raptor rocket engines, and the Starship on top has six itself. This stacking, which happened at SpaceX's development site in south Texas, is a significant development because it's the first time the two elements of the full Starship system have been united as one. This is the configuration that will be used for launching the next Starship prototype on its test mission that will hopefully achieve orbit.

It sounds like a plan concocted by a supervillain, if that villain's dastardly end was to provide cheap, clean power all over the world: launch a set of three-kilometer-wide solar arrays that beam the sun's energy to the surface of the Earth. The Space-based Solar Power Project has been underway since at least 2013, when the first donation from Donald and Brigitte Bren came through. Donald Bren is the chairman of Irvine Company and on the Caltech board of trustees, and after hearing about the idea of space-based solar in Popular Science, he proposed to fund a research project at the university — and since then has given more than $100 million for the purpose.
